Assignment 4: Climate Science – Critical Analysis of Arguments

In this assignment, you will be using the website to discuss one of the most used arguments against human-caused global warming. Your task is to choose ONE of the most used climate myths, explain what the argument says in your own words, and thoroughly explain why this argument does not hold up against the scientific evidence.

Only the top ten myths are listed, but you can view a list of 173 myths. Make sure you understand one thoroughly before selecting it as your topic. You will have to cite and discuss at least one data set that debunks the climate myth you choose.

1. Which Most Used Climate Myth did you choose to discuss? Please list the title as seen on the website (e.g., #23 “It’s freaking cold!” or #20 “Al Gore got it wrong” or #8 “Animals and plants can adapt.”) (1 point)

2. Click on the climate myth you chose and explain in your own words what the skeptic argument is (i.e., summarize the myth in your own words) (3 points)

3. List of three additional sources, and brief 1-2 sentence summaries of what those sources say about the myth (do they support or refute the myth and why): (2 pts each = 6 pts total)

4. List and describe TWO arguments that are based on scientific evidence that disprove your chosen climate myth. For each scientific argument, explain what it says or demonstrates, and reference the data the scientists cite. Scientific argument 1 (1 point): What it says/demonstrates (3 points): Data cited (2 points): Scientific argument 2 (1 point): What it says/demonstrates (3 points): Data cited (2 points):

5. After exploring the website and other websites, what do you think is one way you can, as an informed citizen, be confident in data or information presented to the public? (2 pts)

Introduction

Climate change has become one of the most debatable topics in contemporary discourse, often clouded by myths and misconceptions. In this analysis, I will examine the popular climate myth titled "#3 'Climate has changed before',” which argues that climate change is a natural phenomenon that has occurred throughout Earth's history. However, this perspective neglects the overwhelming evidence demonstrating that current climate change is significantly driven by human activities. This paper will explore the assertions behind this myth and provide scientific evidence that contradicts it.

Understanding the Climate Myth

The climate myth "#3 'Climate has changed before'" suggests that the Earth’s climate is always fluctuating due to natural processes, and therefore, the current shifts could merely be part of a long-standing cycle. Advocates of this myth imply that because the planet has experienced changing climates over millennia, the present warming trend, attributed to human activities such as burning fossil fuels and deforestation, is inconsequential. This argument often oversimplifies the complex interactions between natural factors (like volcanic eruptions and solar influences) and anthropogenic influences on climate.

Supporting Literature

To better understand this myth, I researched three external sources that discuss its veracity:

  • Source 1: National Oceanic and Atmospheric Administration (NOAA) - This source emphasizes that while climate variability has existed, current changes are unprecedented in the context of recent geological history, primarily driven by greenhouse gas emissions.
  • Source 2: Intergovernmental Panel on Climate Change (IPCC) - The IPCC report explicitly states that the rate of warming since the late 20th century is alarming and far exceeds natural variability, affirming that human actions are the primary cause.
  • Source 3: American Association for the Advancement of Science (AAAS) - This organization notes that while climate has fluctuated, the rapid alterations observed today correlate directly with human activities, revealing critical signals of anthropogenic climate change.

Scientific Arguments Against the Myth

The first scientific argument against the myth that climate has changed before lies in the geological data indicating the current rate of change. According to a 2013 study published in “Nature” by Foster et al., temperature increases over the last century are primarily attributed to human influence, with the atmospheric carbon dioxide levels surpassing natural variation (Foster et al., 2013). The data shows that the current rate of temperature rise is approximately 10 times faster than the average rate of warming observed in the past, dispelling the notion that we are simply experiencing cyclical fluctuations.

The second argument comes from the analysis of ice cores detailed by researchers in a 2008 study that examines historical climate patterns. These ice cores reveal that while there have been periods of warming and cooling, the composition of atmospheric gases has significantly shifted with human industrialization. According to the findings published in “Science,” the concentrations of carbon dioxide and methane are higher than they have been for at least 800,000 years, underscoring the pivotal role of human activity in current climate dynamics (Lüthi et al., 2008).

Being an Informed Citizen

As an informed citizen, a strategy I can employ to critically analyze information presented to the public is to seek out reputable scientific studies and consensus reports from established organizations like the IPCC or NOAA. Evaluating the methodologies and data behind claims is crucial. Scrutinizing the qualifications of the authors and the transparency of data sources can also help ensure the reliability of the information I consume. Utilizing critical thinking skills to differentiate between peer-reviewed studies and unverified claims can significantly aid in understanding the nature of climate change.

Conclusion

The climate myth "#3 'Climate has changed before'" oversimplifies the complex nature of climate variability and disregards the substantial body of scientific evidence demonstrating human-induced climate change. Through analyzing credible studies and reports, it becomes evident that current climate alterations cannot be reduced to mere historical patterns. By fostering critical thinking and seeking credible sources, individuals can better understand the intricacies of global climate challenges we face today.
