  1. You are expected to submit a summary of a current climate / environmental-related article from the mainstream press, along with your personal evaluation/reflection. Using a recent news article from a reliable source, please feel encouraged to explore topics that include extreme weather (e.g. winter storms, drought), climate change, energy (e.g. decreases in crude oil price, fracking, coal mining, nuclear power plants, alternative energy, etc), adaptation of animal behavior to recent climate change (including mammals, insects, fish, etc), policy related topics (international climate change conferences), and more. Due by January 28.
    Guidelines of this assignment are:

    • Article summary: Your own summary – do not copy from an original source (1 page).
    • Reflection: Your own discussion about the topic(s) of the article. Please apply your knowledge from this course and incorporate it into your discussion (1 page)
    • Maximum pages: 2
    • Font type and size: Times New Roman/Times, 12-point size, double spaced
    • Data (optional): include source data

Lecture 2
4 Fundamental Questions &

Weather versus Climate

1. Rank your sense of alarm about global warming, where 1 is
“not too worried, much less important than other problems”
and 5 is “very worried, about the most important problem
we face.”

6 Questions about Global Warming
Here are fundamental questions associated with recent changes in our earth’s
climate. Please take a moment to write down your answers and think about
them.

2. Is the greenhouse effect considered an established
scientific theory?

6 Questions about Global Warming
You may or may not have heard some of these critical terminologies used
by climate scientists. They will be further discussed in this course.

3. What is Climate Sensitivity?
4. What is Radiative Forcing?
5. What is the pre-industrial atmospheric concentration of CO2?

280ppm

6. What percentage of the world’s energy comes from
renewables?
About 11% of the world’s marketed energy consumption is from renewable
energy sources (biofuels, biomass, geothermal, hydropower, solar, and
wind) with a projection for 15% by 2040 (U.S. Energy Information
Administration (EIA)

�Global temperatures are rising due to human emissions of
greenhouse gases and their resultant accumulation in the

atmosphere�

Is this true?
What are the fundamental questions that we have to ask
ourselves to test this notion? (5 min group discussion).

1.  Are global temperatures rising?

2.  Is the atmospheric concentration of greenhouse gases increasing?

3.  Is the concentration of greenhouse gases increasing because of us?

4.  Is global warming due to increasing emissions of greenhouse gases?

Under the current administration, we have witnessed the Environmental Protection
Agency (EPA) remove the climate change section from its website. Also, the White
House’s website has removed the entire climate change section that ties climate
change to anthropogenic cause (e.g. The Reuters, January 25, 2017,
http://www.reuters.com/article/us-usa-trump-epa-climatechange-idUSKBN15906G,
The Gardians, May 14, 2017, https://www.theguardian.com/us-
news/2017/may/14/donald-trump-climate-change-mentions-government-websites).
As a result, It is even more important for you to learn about the scientific mechanisms
of climate change and develop an understanding of what the scientific data implies.

Let’s think like a scientist! Assume that you encounter someone who asks you “Is this
true?” to the above mentioned statement which was deleted from the White House’s
and EPA’s website. To answer this question, what fundamental questions come to
mind?

Here are four fundamental questions that need to be addressed. The answers will be
covered throughout this course, and you should be able to address these questions
scientifically.
