Definition of thesis

Did you know.

In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.

What is a thesis | A Complete Guide with Examples

Madalsa

Table of Contents

A thesis is a comprehensive academic paper based on your original research that presents new findings, arguments, and ideas of your study. It’s typically submitted at the end of your master’s degree or as a capstone of your bachelor’s degree.

However, writing a thesis can be laborious, especially for beginners. From the initial challenge of pinpointing a compelling research topic to organizing and presenting findings, the process is filled with potential pitfalls.

Therefore, to help you, this guide talks about what is a thesis. Additionally, it offers revelations and methodologies to transform it from an overwhelming task to a manageable and rewarding academic milestone.

What is a thesis?

A thesis is an in-depth research study that identifies a particular topic of inquiry and presents a clear argument or perspective about that topic using evidence and logic.

Writing a thesis showcases your ability of critical thinking, gathering evidence, and making a compelling argument. Integral to these competencies is thorough research, which not only fortifies your propositions but also confers credibility to your entire study.

Furthermore, there's another phenomenon you might often confuse with the thesis: the ' working thesis .' However, they aren't similar and shouldn't be used interchangeably.

A working thesis, often referred to as a preliminary or tentative thesis, is an initial version of your thesis statement. It serves as a draft or a starting point that guides your research in its early stages.

As you research more and gather more evidence, your initial thesis (aka working thesis) might change. It's like a starting point that can be adjusted as you learn more. It's normal for your main topic to change a few times before you finalize it.

While a thesis identifies and provides an overarching argument, the key to clearly communicating the central point of that argument lies in writing a strong thesis statement.

What is a thesis statement?

A strong thesis statement (aka thesis sentence) is a concise summary of the main argument or claim of the paper. It serves as a critical anchor in any academic work, succinctly encapsulating the primary argument or main idea of the entire paper.

Typically found within the introductory section, a strong thesis statement acts as a roadmap of your thesis, directing readers through your arguments and findings. By delineating the core focus of your investigation, it offers readers an immediate understanding of the context and the gravity of your study.

Furthermore, an effectively crafted thesis statement can set forth the boundaries of your research, helping readers anticipate the specific areas of inquiry you are addressing.

Different types of thesis statements

A good thesis statement is clear, specific, and arguable. Therefore, it is necessary for you to choose the right type of thesis statement for your academic papers.

Thesis statements can be classified based on their purpose and structure. Here are the primary types of thesis statements:

Argumentative (or Persuasive) thesis statement

Purpose : To convince the reader of a particular stance or point of view by presenting evidence and formulating a compelling argument.

Example : Reducing plastic use in daily life is essential for environmental health.

Analytical thesis statement

Purpose : To break down an idea or issue into its components and evaluate it.

Example : By examining the long-term effects, social implications, and economic impact of climate change, it becomes evident that immediate global action is necessary.

Expository (or Descriptive) thesis statement

Purpose : To explain a topic or subject to the reader.

Example : The Great Depression, spanning the 1930s, was a severe worldwide economic downturn triggered by a stock market crash, bank failures, and reduced consumer spending.

Cause and effect thesis statement

Purpose : To demonstrate a cause and its resulting effect.

Example : Overuse of smartphones can lead to impaired sleep patterns, reduced face-to-face social interactions, and increased levels of anxiety.

Compare and contrast thesis statement

Purpose : To highlight similarities and differences between two subjects.

Example : "While both novels '1984' and 'Brave New World' delve into dystopian futures, they differ in their portrayal of individual freedom, societal control, and the role of technology."

When you write a thesis statement , it's important to ensure clarity and precision, so the reader immediately understands the central focus of your work.

What is the difference between a thesis and a thesis statement?

While both terms are frequently used interchangeably, they have distinct meanings.

A thesis refers to the entire research document, encompassing all its chapters and sections. In contrast, a thesis statement is a brief assertion that encapsulates the central argument of the research.

Here’s an in-depth differentiation table of a thesis and a thesis statement.

Now, to craft a compelling thesis, it's crucial to adhere to a specific structure. Let’s break down these essential components that make up a thesis structure

15 components of a thesis structure

Navigating a thesis can be daunting. However, understanding its structure can make the process more manageable.

Here are the key components or different sections of a thesis structure:

Your thesis begins with the title page. It's not just a formality but the gateway to your research.

title-page-of-a-thesis

Here, you'll prominently display the necessary information about you (the author) and your institutional details.

  • Title of your thesis
  • Your full name
  • Your department
  • Your institution and degree program
  • Your submission date
  • Your Supervisor's name (in some cases)
  • Your Department or faculty (in some cases)
  • Your University's logo (in some cases)
  • Your Student ID (in some cases)

In a concise manner, you'll have to summarize the critical aspects of your research in typically no more than 200-300 words.

Abstract-section-of-a-thesis

This includes the problem statement, methodology, key findings, and conclusions. For many, the abstract will determine if they delve deeper into your work, so ensure it's clear and compelling.

Acknowledgments

Research is rarely a solitary endeavor. In the acknowledgments section, you have the chance to express gratitude to those who've supported your journey.

Acknowledgement-section-of-a-thesis

This might include advisors, peers, institutions, or even personal sources of inspiration and support. It's a personal touch, reflecting the humanity behind the academic rigor.

Table of contents

A roadmap for your readers, the table of contents lists the chapters, sections, and subsections of your thesis.

Table-of-contents-of-a-thesis

By providing page numbers, you allow readers to navigate your work easily, jumping to sections that pique their interest.

List of figures and tables

Research often involves data, and presenting this data visually can enhance understanding. This section provides an organized listing of all figures and tables in your thesis.

List-of-tables-and-figures-in-a-thesis

It's a visual index, ensuring that readers can quickly locate and reference your graphical data.

Introduction

Here's where you introduce your research topic, articulate the research question or objective, and outline the significance of your study.

Introduction-section-of-a-thesis

  • Present the research topic : Clearly articulate the central theme or subject of your research.
  • Background information : Ground your research topic, providing any necessary context or background information your readers might need to understand the significance of your study.
  • Define the scope : Clearly delineate the boundaries of your research, indicating what will and won't be covered.
  • Literature review : Introduce any relevant existing research on your topic, situating your work within the broader academic conversation and highlighting where your research fits in.
  • State the research Question(s) or objective(s) : Clearly articulate the primary questions or objectives your research aims to address.
  • Outline the study's structure : Give a brief overview of how the subsequent sections of your work will unfold, guiding your readers through the journey ahead.

The introduction should captivate your readers, making them eager to delve deeper into your research journey.

Literature review section

Your study correlates with existing research. Therefore, in the literature review section, you'll engage in a dialogue with existing knowledge, highlighting relevant studies, theories, and findings.

Literature-review-section-thesis

It's here that you identify gaps in the current knowledge, positioning your research as a bridge to new insights.

To streamline this process, consider leveraging AI tools. For example, the SciSpace literature review tool enables you to efficiently explore and delve into research papers, simplifying your literature review journey.

Methodology

In the research methodology section, you’ll detail the tools, techniques, and processes you employed to gather and analyze data. This section will inform the readers about how you approached your research questions and ensures the reproducibility of your study.

Methodology-section-thesis

Here's a breakdown of what it should encompass:

  • Research Design : Describe the overall structure and approach of your research. Are you conducting a qualitative study with in-depth interviews? Or is it a quantitative study using statistical analysis? Perhaps it's a mixed-methods approach?
  • Data Collection : Detail the methods you used to gather data. This could include surveys, experiments, observations, interviews, archival research, etc. Mention where you sourced your data, the duration of data collection, and any tools or instruments used.
  • Sampling : If applicable, explain how you selected participants or data sources for your study. Discuss the size of your sample and the rationale behind choosing it.
  • Data Analysis : Describe the techniques and tools you used to process and analyze the data. This could range from statistical tests in quantitative research to thematic analysis in qualitative research.
  • Validity and Reliability : Address the steps you took to ensure the validity and reliability of your findings to ensure that your results are both accurate and consistent.
  • Ethical Considerations : Highlight any ethical issues related to your research and the measures you took to address them, including — informed consent, confidentiality, and data storage and protection measures.

Moreover, different research questions necessitate different types of methodologies. For instance:

  • Experimental methodology : Often used in sciences, this involves a controlled experiment to discern causality.
  • Qualitative methodology : Employed when exploring patterns or phenomena without numerical data. Methods can include interviews, focus groups, or content analysis.
  • Quantitative methodology : Concerned with measurable data and often involves statistical analysis. Surveys and structured observations are common tools here.
  • Mixed methods : As the name implies, this combines both qualitative and quantitative methodologies.

The Methodology section isn’t just about detailing the methods but also justifying why they were chosen. The appropriateness of the methods in addressing your research question can significantly impact the credibility of your findings.

Results (or Findings)

This section presents the outcomes of your research. It's crucial to note that the nature of your results may vary; they could be quantitative, qualitative, or a mix of both.

Results-section-thesis

Quantitative results often present statistical data, showcasing measurable outcomes, and they benefit from tables, graphs, and figures to depict these data points.

Qualitative results , on the other hand, might delve into patterns, themes, or narratives derived from non-numerical data, such as interviews or observations.

Regardless of the nature of your results, clarity is essential. This section is purely about presenting the data without offering interpretations — that comes later in the discussion.

In the discussion section, the raw data transforms into valuable insights.

Start by revisiting your research question and contrast it with the findings. How do your results expand, constrict, or challenge current academic conversations?

Dive into the intricacies of the data, guiding the reader through its implications. Detail potential limitations transparently, signaling your awareness of the research's boundaries. This is where your academic voice should be resonant and confident.

Practical implications (Recommendation) section

Based on the insights derived from your research, this section provides actionable suggestions or proposed solutions.

Whether aimed at industry professionals or the general public, recommendations translate your academic findings into potential real-world actions. They help readers understand the practical implications of your work and how it can be applied to effect change or improvement in a given field.

When crafting recommendations, it's essential to ensure they're feasible and rooted in the evidence provided by your research. They shouldn't merely be aspirational but should offer a clear path forward, grounded in your findings.

The conclusion provides closure to your research narrative.

It's not merely a recap but a synthesis of your main findings and their broader implications. Reconnect with the research questions or hypotheses posited at the beginning, offering clear answers based on your findings.

Conclusion-section-thesis

Reflect on the broader contributions of your study, considering its impact on the academic community and potential real-world applications.

Lastly, the conclusion should leave your readers with a clear understanding of the value and impact of your study.

References (or Bibliography)

Every theory you've expounded upon, every data point you've cited, and every methodological precedent you've followed finds its acknowledgment here.

References-section-thesis

In references, it's crucial to ensure meticulous consistency in formatting, mirroring the specific guidelines of the chosen citation style .

Proper referencing helps to avoid plagiarism , gives credit to original ideas, and allows readers to explore topics of interest. Moreover, it situates your work within the continuum of academic knowledge.

To properly cite the sources used in the study, you can rely on online citation generator tools  to generate accurate citations!

Here’s more on how you can cite your sources.

Often, the depth of research produces a wealth of material that, while crucial, can make the core content of the thesis cumbersome. The appendix is where you mention extra information that supports your research but isn't central to the main text.

Appendices-section-thesis

Whether it's raw datasets, detailed procedural methodologies, extended case studies, or any other ancillary material, the appendices ensure that these elements are archived for reference without breaking the main narrative's flow.

For thorough researchers and readers keen on meticulous details, the appendices provide a treasure trove of insights.

Glossary (optional)

In academics, specialized terminologies, and jargon are inevitable. However, not every reader is versed in every term.

The glossary, while optional, is a critical tool for accessibility. It's a bridge ensuring that even readers from outside the discipline can access, understand, and appreciate your work.

Glossary-section-of-a-thesis

By defining complex terms and providing context, you're inviting a wider audience to engage with your research, enhancing its reach and impact.

Remember, while these components provide a structured framework, the essence of your thesis lies in the originality of your ideas, the rigor of your research, and the clarity of your presentation.

As you craft each section, keep your readers in mind, ensuring that your passion and dedication shine through every page.

Thesis examples

To further elucidate the concept of a thesis, here are illustrative examples from various fields:

Example 1 (History): Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807 by Suchait Kahlon.
Example 2 (Climate Dynamics): Influence of external forcings on abrupt millennial-scale climate changes: a statistical modelling study by Takahito Mitsui · Michel Crucifix

  • Would the thesis be understandable and valuable to someone in your field?

Ensure to use this checklist to leave no ground for doubt or missed information in your thesis.

After writing your thesis, the next step is to discuss and defend your findings verbally in front of a knowledgeable panel. You’ve to be well prepared as your professors may grade your presentation abilities.

Preparing your thesis defense

A thesis defense, also known as "defending the thesis," is the culmination of a scholar's research journey. It's the final frontier, where you’ll present their findings and face scrutiny from a panel of experts.

Typically, the defense involves a public presentation where you’ll have to outline your study, followed by a question-and-answer session with a committee of experts. This committee assesses the validity, originality, and significance of the research.

The defense serves as a rite of passage for scholars. It's an opportunity to showcase expertise, address criticisms, and refine arguments. A successful defense not only validates the research but also establishes your authority as a researcher in your field.

Here’s how you can effectively prepare for your thesis defense .

Now, having touched upon the process of defending a thesis, it's worth noting that scholarly work can take various forms, depending on academic and regional practices.

One such form, often paralleled with the thesis, is the 'dissertation.' But what differentiates the two?

Dissertation vs. Thesis

Often used interchangeably in casual discourse, they refer to distinct research projects undertaken at different levels of higher education.

To the uninitiated, understanding their meaning might be elusive. So, let's demystify these terms and delve into their core differences.

Here's a table differentiating between the two.

Wrapping up

From understanding the foundational concept of a thesis to navigating its various components, differentiating it from a dissertation, and recognizing the importance of proper citation — this guide covers it all.

As scholars and readers, understanding these nuances not only aids in academic pursuits but also fosters a deeper appreciation for the relentless quest for knowledge that drives academia.

It’s important to remember that every thesis is a testament to curiosity, dedication, and the indomitable spirit of discovery.

Good luck with your thesis writing!

Frequently Asked Questions

A thesis typically ranges between 40-80 pages, but its length can vary based on the research topic, institution guidelines, and level of study.

A PhD thesis usually spans 200-300 pages, though this can vary based on the discipline, complexity of the research, and institutional requirements.

To identify a thesis topic, consider current trends in your field, gaps in existing literature, personal interests, and discussions with advisors or mentors. Additionally, reviewing related journals and conference proceedings can provide insights into potential areas of exploration.

The conceptual framework is often situated in the literature review or theoretical framework section of a thesis. It helps set the stage by providing the context, defining key concepts, and explaining the relationships between variables.

A thesis statement should be concise, clear, and specific. It should state the main argument or point of your research. Start by pinpointing the central question or issue your research addresses, then condense that into a single statement, ensuring it reflects the essence of your paper.

  • Literary Terms
  • Definition & Examples
  • When & How to Write a Thesis

I. What is a Thesis?

The thesis (pronounced thee -seez), also known as a thesis statement, is the sentence that introduces the main argument or point of view of a composition (formal essay, nonfiction piece, or narrative). It is the main claim that the author is making about that topic and serves to summarize and introduce that writing that will be discussed throughout the entire piece. For this reason, the thesis is typically found within the first introduction paragraph.

II. Examples of Theses

Here are a few examples of theses which may be found in the introductions of a variety of essays :

In “The Mending Wall,” Robert Frost uses imagery, metaphor, and dialogue to argue against the use of fences between neighbors.

In this example, the thesis introduces the main subject (Frost’s poem “The Mending Wall”), aspects of the subject which will be examined (imagery, metaphor, and dialogue) and the writer’s argument (fences should not be used).

While Facebook connects some, overall, the social networking site is negative in that it isolates users, causes jealousy, and becomes an addiction.

This thesis introduces an argumentative essay which argues against the use of Facebook due to three of its negative effects.

During the college application process, I discovered my willingness to work hard to achieve my dreams and just what those dreams were.

In this more personal example, the thesis statement introduces a narrative essay which will focus on personal development in realizing one’s goals and how to achieve them.

III. The Importance of Using a Thesis

Theses are absolutely necessary components in essays because they introduce what an essay will be about. Without a thesis, the essay lacks clear organization and direction. Theses allow writers to organize their ideas by clearly stating them, and they allow readers to be aware from the beginning of a composition’s subject, argument, and course. Thesis statements must precisely express an argument within the introductory paragraph of the piece in order to guide the reader from the very beginning.

IV. Examples of Theses in Literature

For examples of theses in literature, consider these thesis statements from essays about topics in literature:

In William Shakespeare’s “ Sonnet 46,” both physicality and emotion together form powerful romantic love.

This thesis statement clearly states the work and its author as well as the main argument: physicality and emotion create romantic love.

In The Scarlet Letter, Nathaniel Hawthorne symbolically shows Hester Prynne’s developing identity through the use of the letter A: she moves from adulteress to able community member to angel.

In this example, the work and author are introduced as well as the main argument and supporting points: Prynne’s identity is shown through the letter A in three ways: adulteress, able community member, and angel.

John Keats’ poem “To Autumn” utilizes rhythm, rhyme, and imagery to examine autumn’s simultaneous birth and decay.

This thesis statement introduces the poem and its author along with an argument about the nature of autumn. This argument will be supported by an examination of rhythm, rhyme, and imagery.

V. Examples of Theses in Pop Culture

Sometimes, pop culture attempts to make arguments similar to those of research papers and essays. Here are a few examples of theses in pop culture:

FOOD INC TEASER TRAILER - "More than a terrific movie -- it's an important movie." - Ent Weekly

America’s food industry is making a killing and it’s making us sick, but you have the power to turn the tables.

The documentary Food Inc. examines this thesis with evidence throughout the film including video evidence, interviews with experts, and scientific research.

Blackfish Official Trailer #1 (2013) - Documentary Movie HD

Orca whales should not be kept in captivity, as it is psychologically traumatizing and has caused them to kill their own trainers.

Blackfish uses footage, interviews, and history to argue for the thesis that orca whales should not be held in captivity.

VI. Related Terms

Just as a thesis is introduced in the beginning of a composition, the hypothesis is considered a starting point as well. Whereas a thesis introduces the main point of an essay, the hypothesis introduces a proposed explanation which is being investigated through scientific or mathematical research. Thesis statements present arguments based on evidence which is presented throughout the paper, whereas hypotheses are being tested by scientists and mathematicians who may disprove or prove them through experimentation. Here is an example of a hypothesis versus a thesis:

Hypothesis:

Students skip school more often as summer vacation approaches.

This hypothesis could be tested by examining attendance records and interviewing students. It may or may not be true.

Students skip school due to sickness, boredom with classes, and the urge to rebel.

This thesis presents an argument which will be examined and supported in the paper with detailed evidence and research.

Introduction

A paper’s introduction is its first paragraph which is used to introduce the paper’s main aim and points used to support that aim throughout the paper. The thesis statement is the most important part of the introduction which states all of this information in one concise statement. Typically, introduction paragraphs require a thesis statement which ties together the entire introduction and introduces the rest of the paper.

VII. Conclusion

Theses are necessary components of well-organized and convincing essays, nonfiction pieces, narratives , and documentaries. They allow writers to organize and support arguments to be developed throughout a composition, and they allow readers to understand from the beginning what the aim of the composition is.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

  • tells the reader how you will interpret the significance of the subject matter under discussion.
  • is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
  • directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
  • makes a claim that others might dispute.
  • is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

  • Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
  • Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
  • Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
  • Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
  • Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
  • Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

  • Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
  • Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
  • Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
  • Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
  • Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

  • Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.
  • Do I answer the question? Yes!
  • Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
  • Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
  • Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
  • Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

Make a Gift

Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."

An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)

A good thesis has two parts. It should tell what you plan to argue, and it should "telegraph" how you plan to argue—that is, what particular support for your claim is going where in your essay.

Steps in Constructing a Thesis

First, analyze your primary sources.  Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)

Once you have a working thesis, write it down.  There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.

Keep your thesis prominent in your introduction.  A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.

Anticipate the counterarguments.  Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)

This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.

Some Caveats and Some Examples

A thesis is never a question.  Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.

A thesis is never a list.  "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.

A thesis should never be vague, combative or confrontational.  An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.

An effective thesis has a definable, arguable claim.  "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."

A thesis should be as clear and specific as possible.  Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."

Writing Explained

What is a Thesis? Definition, Examples of Theses in Literature

Home » The Writer’s Dictionary » What is a Thesis? Definition, Examples of Theses in Literature

Thesis definition: A thesis is a statement in which the writer conveys his position regarding a topic.

What is a Thesis?

A thesis statement refers to part of an essay where the writer establishes his position regarding a topic. This is the position that the writer will further explore throughout his paper.

Example of Thesis

  • Topic : religious freedom.
  • Thesis : All citizens of the United States should be allowed to exercise the religion of their choice freely without interference from government.
  • Explanation : In this thesis statement, the writer has taken the position that all citizens should be free to worship and practice their religion as they see fit. The government should not pressure citizens into any religion, and it should not persecute members of any faith community.

The Importance of a Thesis Statement

Thesis statements are important in order to establish the writer’s position regarding a topic or idea. They help to introduce the essay and set a focus for the reader.

Narrative thesis statements are found in narrative essays or in literature. They set the scene for the lesson that will be explored or taught through the piece.

Famous opening lines that exemplify a narrative thesis:

  • The following narrative thesis is found in A Tale of Two Cities by Charles Dickens:

“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair.”

The Function of Thesis in Literature

Narrative thesis statements are important in literature in order to establish the purpose for the work or introduce the lesson that the novel will attempt to teach. This allows the reader to have a focus when beginning the novel in order to effectively engage them into the story.

Examples of Theses in Literature

In the memoir, I am Malala by Malala Yousafzai, a thesis statement can be found in the beginning pages of her story.

  • “One year ago I left my home for school and never returned. I was shot by a Taliban bullet and was flown out of Pakistan unconscious. Some people say I will never return home, but I believe firmly in my heart that I will. To be torn from the country that you love is not something to wish on anyone.”

In this thesis statement, Yousafzai establishes the basis of her memoir, which is to tell the story of how she was forced to leave her home.

In Vladmir Nabokov’s Lolita , a thesis can be seen in the line, “Lolita, light of my life, the fire of my loins”.

Here the narrator establishes the identity of the young nymph that he is unhealthily obsessed with in the story. Lolita is a young child while he is a grown man; therefore, this statement creates the uneasy feeling about him that continues throughout the novel.

Summary: What Are Theses?

Define thesis in literature: In summation, a thesis statement establishes a purpose in the piece of writing. It may establish the lesson or story to be told, or in an essay it may establish the position the writer assumes when exploring a topic.

Either way, it is important for the thesis to be clear in order to effectively convey the writer’s message.

Final Example:

In Edgar Allan Poe’s “The Cask of Amontillado,” the thesis statement can be found in the first line of the short story. Montresor immediately states his purpose, “the thousand injuries of Fortunato I had borne as best I could, but when he ventured upon insult I vowed revenge.”

In this statement, Montresor states that he will be seeking revenge after being treated wrongly by Fortunato. By beginning the story with the narrative thesis establishes the purpose for the remainder of the piece.

OASIS: Writing Center

Writing a paper: thesis statements, basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

  • In this essay, I argue ____, using ______ to assert _____.
  • While scholars have often argued ______, I argue______, because_______.
  • Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

Thesis Definition

The thesis is one of the most important concepts in college expository writing. A thesis sentence focuses your ideas for the paper; it's your argument or insight or viewpoint crystallized into a single sentence that gives the reader your main idea. It's not only useful for the reading audience to understand the purpose of the essay; this purpose is also useful for you as a writer, as it indicates the type of support that will follow in the paper and may indicate a logical structure or order for that support. Thus, you need to have a good grasp of the concept of thesis in order to proceed.

The thesis identifies two basics:

  • what your ideas are about, and
  • what your ideas are (i.e. what you will be trying to prove).

There are two parts to a thesis sentence that reflect these basics.

  • The topic in the thesis tells what you are writing about.
  • The angle in the thesis tells what your ideas are about the topic (again, what you are trying to prove).

For example:

  • All successful college students have certain basic characteristics. [The main topic is about college students, while the idea or angle about the topic is that successful students share certain characteristics. The thesis indicates the type of support needed--discussion of those characteristics that contribute to college success.]
  • For most adult students returning to college, the problems that they face along the way are outweighed by their achievements. [The main topic is about adult college students, while the idea or angle about the topic is that problems are outweighed by achievements. The thesis indicates the type of support needed and the order of that support--an explanation of the problems first and then an explanation of achievements second.]
  • Adult students returning to college make up a higher percentage of entering students than they did twenty years ago because of a number of statistical, economic, and social reasons. [The main topic is about adult students returning to college, while the idea or angle about the topic is that there are reasons for the higher percentage of adults returning to college. The thesis indicates the type of support needed and the order of that support--an explanation of the statistical reasons first, economic reasons second, and social reasons third.]

Do you understand the basic topic and angle concept? If so, then there are a few more things to consider about the thesis. (And if not, now's the time to start asking a learning coach for assistance, so Email [email protected] ). It's important to investigate additional thesis characteristics at this point to make sure that you'll be creating a working thesis sentence that is workable and appropriate for college essays.  In addition to knowing what a thesis is, you need to know what a thesis is not. A thesis sentence's angle should NOT be:

  • Too broad. For example, the following thesis really doesn't pinpoint a specific insight about the topic:  Adult students returning to college have a hard time. In what ways do adult students have a hard time? You'd need to identify a more specific insight in this angle.
  • Too narrow a statement of fact. For example, the following thesis really cannot be developed into a full essay because the angle doesn't contain the writer's own thoughts or insights about the subject:  Adult students returning to college read an average of 7.5 books per term. A reader may respond by saying, "So what?" A narrow statement of fact does not contain your own personal analysis, argument, or interpretation of the topic--that all-important angle which a thesis must have.
  • An announcement. For example, the following really is not a thesis at all because it lacks an angle that gives the writer's own insight into the topic: My topic is the adult student returning to college. Again, "So what?" What's the reader's idea here?

Once you create a working thesis, you should assess it to make sure that it fulfills thesis characteristics.  Make sure it has a clear topic (indication of what the thesis is about) and angle (what your own ideas are about the topic, i.e. what you are trying to prove). Make sure that the angle is not too broad, too narrow, a statement of fact, or an announcement. Work with the angle to make it indicate the order of your support, if you choose to do that for yourself or for your reading audience. And realize that the thesis is a working thesis until you finalize the essay (it's okay to revise the thesis as you go along, just as long as you retain important thesis characteristics.)

A thesis ( THEE-ses ) is the main (or controlling) idea of an essay , report , speech , or research paper , sometimes written as a single declarative sentence known as a thesis statement . A thesis may be implied rather than stated directly. Plural: theses . It's also known as a thesis statement, thesis sentence, controlling idea.

In the classical rhetorical exercises known as the  progymnasmata , the  thesis is an exercise that requires a student to argue a case for one side or the other.

  • Drafting and Revising a Thesis "It's a good idea to formulate a thesis early in the writing process , perhaps by jotting it on scratch paper, by putting it at the head of a rough outline , or by attempting to write an introductory paragraph that includes the thesis. Your tentative thesis will probably be less graceful than the thesis you include in the final version of your essay. Here, for example, is one student's early effort: Although they both play percussion instruments, drummers and percussionists are very different. The thesis that appeared in the final draft of the student's paper was more polished: Two types of musicians play percussion instruments--drummers and percussionists--and they are as different as Quiet Riot and the New York Philharmonic.

A woman in a VR headset looking up, mouth agape in 3 Body Problem

With Netflix’s 3 Body Problem imminent, you might naturally be intrigued by The Three-Body Problem , the science fiction novel by Cixin Liu.

First of all: I cannot explain why the show is 3 Body Problem and the book is The Three-Body Problem . Frankly, this decision drives me bananas. But it does make distinguishing the two in articles like this one easier, and as you’ll soon see, things are going to get complicated enough as is.

What is The Three-Body Problem about?

The simple version is that it’s a story about humanity’s first contact with an alien species. What makes it special is that it’s a very odd first contact story, centering on a wildly immersive VR video game and how it may be connected to the mysterious deaths of the world’s leading scientists. First contact is the light at the end of the story’s tunnel: read the back of the book and you know it’s coming, but how it happens is something you discover by reading.

Why is it such a big deal?

First serialized in China in 2006, The Three-Body Problem quickly racked up accolades upon its 2014 English debut, becoming the first Asian novel to win the Hugo Award for Best Novel. But unusually for such a hard sci-fi novel, The Three-Body Problem quickly escaped the orbit of speculative fiction circles and received glowing write-ups in mainstream press outlets like The New York Times , NPR , and, famously, a shoutout from President Barack Obama . Bob’s Burgers even did a Three-Body Problem episode . It was a big thing!

It’s also a work that some would call unadaptable: The Three-Body Problem has some weird shit going on in its VR game and eventually sets up a conflict that may or may not span centuries.

Remind me what you mean by ‘hard’ sci-fi.

The Three-Body Problem is a brainy book that is very committed to elaborating on the work of a lot of smart characters solving very opaque mysteries. This does not mean it’s impenetrable to people uninterested in becoming conversant in astrophysics, but it does mean there’s quite a bit of what I call “process porn,” focused primarily (but not exclusively) on existing and/or plausible technology. For the most satisfying version of that, consider films like Arrival or even Spotlight (a great movie for making spreadsheets thrilling). How well The Three-Body Problem ’s take on it works for you will depend on how much you connect with translator (and very good novelist in his own right ) Ken Liu’s interpretation of Cixin Liu’s prose.

It helps that the book begins vividly in the past, during China’s Cultural Revolution in the 1960s — telling a small, personal tragedy that reverberates throughout the first novel as it reaches into the present day and beyond. With that human core in place, it’s easier to get lost in The Three-Body Problem ’s trippy mysteries, and grasp their shocking consequences.

I’m looking up characters from the book and can’t find many in the show. What’s up with that?

Part of what the Netflix adaptation does is relocate a big chunk of the action from China to London, which means lots of changes that ripple outward. Characters are race- and genderbent or reworked and given different names, which makes finding one-to-one analogues for some characters very difficult. But there are very practical concerns that also needed to be addressed, according to the showrunners, and these changes account for that.

“The characters in the book are all spread out in a way, but they don’t know each other, and they don’t connect with each other. Which works really well in a novel, [where] you get inside someone’s head,” co-creator D.B. Weiss told Polygon at a recent press event. “And in television — it’s hard to think of a television show about people who don’t know each other and never meet. Television is about people who know each other, who have strong feelings about each other, interacting with other people about whom they have strong feelings. So we kind of needed to make that happen.”

How much of The Three-Body Problem will 3 Body Problem season 1 adapt?

Pardon? But what if there’s another season?

Oh, there are more books. The Three-Body Problem is the first in a trilogy, known as Remembrance of Earth’s Past. Netflix’s 3 Body Problem is actually an adaptation of the entire trilogy, folding in the novel’s two sequels — The Dark Forest and Death’s End — into its narrative. The first season of the show will cover The Three-Body Problem but will also introduce threads from later books. It’s a comprehensive adaptation, not a piecemeal one.

So you mean it’s done? There’s an end?

Yes, I do mean that. Don’t worry; while David Benioff and D.B. Weiss are most notorious for what happened when the former Game of Thrones showrunners ran out of track laid by their source material, that problem is not present here. They’re also not the only ones in charge, thanks to co-creator Alexander Woo, who has previously worked on excellent series like Manhattan and Wonderfalls . 3 Body Problem will live or die by the adaptation choices made, not for lack of material.

3 Body Problem will premiere on Netflix on March 22.

The Effects of Climate Change

The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

what is meaning of thesis

  • We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
  • Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.

Earth Will Continue to Warm and the Effects Will Be Profound

Effects_page_triptych

Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner.

Effects that scientists had long predicted would result from global climate change are now occurring, such as sea ice loss, accelerated sea level rise, and longer, more intense heat waves.

The magnitude and rate of climate change and associated risks depend strongly on near-term mitigation and adaptation actions, and projected adverse impacts and related losses and damages escalate with every increment of global warming.

what is meaning of thesis

Intergovernmental Panel on Climate Change

Some changes (such as droughts, wildfires, and extreme rainfall) are happening faster than scientists previously assessed. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.

Scientists have high confidence that global temperatures will continue to rise for many decades, mainly due to greenhouse gases produced by human activities.

The IPCC’s Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900. 1 The global average temperature is expected to reach or exceed 1.5 degrees C (about 3 degrees F) within the next few decades. These changes will affect all regions of Earth.

The severity of effects caused by climate change will depend on the path of future human activities. More greenhouse gas emissions will lead to more climate extremes and widespread damaging effects across our planet. However, those future effects depend on the total amount of carbon dioxide we emit. So, if we can reduce emissions, we may avoid some of the worst effects.

The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss the brief, rapidly closing window to secure a liveable future.

Here are some of the expected effects of global climate change on the United States, according to the Third and Fourth National Climate Assessment Reports:

Future effects of global climate change in the United States:

sea level rise

U.S. Sea Level Likely to Rise 1 to 6.6 Feet by 2100

Global sea level has risen about 8 inches (0.2 meters) since reliable record-keeping began in 1880. By 2100, scientists project that it will rise at least another foot (0.3 meters), but possibly as high as 6.6 feet (2 meters) in a high-emissions scenario. Sea level is rising because of added water from melting land ice and the expansion of seawater as it warms. Image credit: Creative Commons Attribution-Share Alike 4.0

Longer Wildfire Season

Warming temperatures have extended and intensified wildfire season in the West, where long-term drought in the region has heightened the risk of fires. Scientists estimate that human-caused climate change has already doubled the area of forest burned in recent decades. By around 2050, the amount of land consumed by wildfires in Western states is projected to further increase by two to six times. Even in traditionally rainy regions like the Southeast, wildfires are projected to increase by about 30%.

Changes in Precipitation Patterns

Climate change is having an uneven effect on precipitation (rain and snow) in the United States, with some locations experiencing increased precipitation and flooding, while others suffer from drought. On average, more winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. Image credit: Marvin Nauman/FEMA

Frost-Free Season (and Growing Season) will Lengthen

The length of the frost-free season, and the corresponding growing season, has been increasing since the 1980s, with the largest increases occurring in the western United States. Across the United States, the growing season is projected to continue to lengthen, which will affect ecosystems and agriculture.

Global Temperatures Will Continue to Rise

Summer of 2023 was Earth's hottest summer on record, 0.41 degrees Fahrenheit (F) (0.23 degrees Celsius (C)) warmer than any other summer in NASA’s record and 2.1 degrees F (1.2 C) warmer than the average summer between 1951 and 1980. Image credit: NASA

Arctic Is Very Likely to Become Ice-Free

Sea ice cover in the Arctic Ocean is expected to continue decreasing, and the Arctic Ocean will very likely become essentially ice-free in late summer if current projections hold. This change is expected to occur before mid-century.

U.S. Regional Effects

Climate change is bringing different types of challenges to each region of the country. Some of the current and future impacts are summarized below. These findings are from the Third 3 and Fourth 4 National Climate Assessment Reports, released by the U.S. Global Change Research Program .

  • Northeast. Heat waves, heavy downpours, and sea level rise pose increasing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries, and ecosystems will be increasingly compromised. Farmers can explore new crop options, but these adaptations are not cost- or risk-free. Moreover, adaptive capacity , which varies throughout the region, could be overwhelmed by a changing climate. Many states and cities are beginning to incorporate climate change into their planning.
  • Northwest. Changes in the timing of peak flows in rivers and streams are reducing water supplies and worsening competing demands for water. Sea level rise, erosion, flooding, risks to infrastructure, and increasing ocean acidity pose major threats. Increasing wildfire incidence and severity, heat waves, insect outbreaks, and tree diseases are causing widespread forest die-off.
  • Southeast. Sea level rise poses widespread and continuing threats to the region’s economy and environment. Extreme heat will affect health, energy, agriculture, and more. Decreased water availability will have economic and environmental impacts.
  • Midwest. Extreme heat, heavy downpours, and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also worsen a range of risks to the Great Lakes.
  • Southwest. Climate change has caused increased heat, drought, and insect outbreaks. In turn, these changes have made wildfires more numerous and severe. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities. In coastal areas, flooding and erosion are additional concerns.

What’s the difference between climate change and global warming?

“Global warming” refers to the long-term warming of the planet. “Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet, including rising sea levels; shrinking mountain glaciers; accelerating ice melt in Greenland, Antarctica and the Arctic; and shifts in flower/plant blooming times.

Is it too late to prevent climate change?

Humans have caused major climate changes to happen already, and we have set in motion more changes still. However, if we stopped emitting greenhouse gases today, the rise in global temperatures would begin to flatten within a few years. Temperatures would then plateau but remain well-elevated for many, many centuries.

Efficient Decentralized Learning Methods for Deep Neural Networks

Decentralized learning is the key to training deep neural networks (DNNs) over large distributed datasets generated at different devices and locations, without the need for a central server. They enable next-generation applications that require DNNs to interact and learn from their environment continuously. The practical implementation of decentralized algorithms brings about its unique set of challenges. In particular, these algorithms should be (a) compatible with time-varying graph structures, (b) compute and communication efficient, and (c) resilient to heterogeneous data distributions. The objective of this thesis is to enable efficient decentralized learning in deep neural networks addressing the abovementioned challenges. Towards this, firstly a communication-efficient decentralized algorithm (Sparse-Push) that supports directed and time-varying graphs with error-compensated communication compression is proposed. Second, a low-precision decentralized training that aims to reduce memory requirements and computational complexity is proposed. Here, we design ”Range-EvoNorm” as the normalization activation layer which is better suited for low-precision decentralized training. Finally, addressing the problem of data heterogeneity, three impactful advancements namely Neighborhood Gradient Mean (NGM), Global Update Tracking (GUT), and Cross-feature Contrastive Loss (CCL) are proposed. NGM utilizes extra communication rounds to obtain cross-agent gradient information whereas GUT tracks global update information with no communication overhead, improving the performance on heterogeneous data. CCL explores an orthogonal direction of using a data-free knowledge distillation approach to handle heterogeneous data in decentralized setups. All the algorithms are evaluated on computer vision tasks using standard image-classification datasets. We conclude this dissertation by presenting a summary of the proposed decentralized methods and their trade-offs for heterogeneous data distributions. Overall, the methods proposed in this thesis address the critical limitations of training deep neural networks in a decentralized setup and advance the state-of-the-art in this domain.
