Question
1. Regarding carbon emissions (CO2), as discovered by the U.S. Air Force, which of the following is true (MARK ALL THAT APPLY):
A.
adding CO2 to the atmosphere, turns up the planet’s thermostat
B.
removing CO2 from the atmosphere, cools things down
C.
whether CO2 is increased or decreased, there isn’t much of an impact on the planet either way
2. How does energy use in the United States (“North America”) compare to the rest of the world?
A.
the U.S. uses less watts per person than any other nation in the world
B.
the U.S. uses over twice as many watts per person as Europeans (the second highest group featured in the graph shown in the video)
C.
the U.S. uses a lot of watts per person as compared to some other nations, but has not yet reached the world's top ten emitters list
3. Using fossils fuels such as coal and oil is an effective way to keep carbon dioxide emissions (CO2) down.
True
False
4. How do we know the rise in atmospheric CO2 is due to human activity, rather than natural sources such as volcanoes?
A.
evidence clearly shows that the increase comes from burning the type of carbon found in ancient plant matter (= fossil fuels)
B.
because humans have only been on earth about 200,000 years and there’s no evidence of increases in atmospheric CO2 prior to this time
C.
both a and b are correct
D.
actually, there is no way of knowing why or how CO2 increases so it’s impossible to say whether this change is the result of human action
5. Which of the following is, or are, happening today? MARK ALL THAT APPLY:
A.
atmospheric CO2 is increasing
B.
the earth’s average temperatures are rising
C.
glaciers and ice sheets are melting
D.
the earth's average temperatures are decreasing
6. Which of the following U.S. government and military branches were identified in the videos as being involved in research on climate change and/or developing and implementing strategies to reduce carbon emissions (MARK ALL THAT APPLY)?
A.
U.S. Department of Defense
B.
U.S. Navy
C.
U.S. Air Force
D.
U.S. Marine Corps
7. Which of the following “renewables” (alternatives to fossil fuels) were addressed in the video and/or are already being successfully used in Texas and some other parts of the U.S. (MARK ALL THAT APPLY)?
A.
solar power
B.
wind power
C.
hydropower
8. If CO2 emissions are not reduced, within several decades the Los Angeles area could warm by 5 degrees on average. There are various negative consequences to public health that could occur as a result of more smog due to higher average temperatures in this region, including (MARK ALL THAT APPLY):
A.
more cases of diabetes
B.
more cases of asthma
C.
an increase in cardiovascular disease, including heart attacks
D.
illness due to a decline in water quality
9. Identify at least TWO changes you can make to your habits and lifestyle that will help reduce carbon emissions over time.
Your examples can come from the “Little Things You Can Do…” video, other online or textbook sources that discuss this topic and/or Prof. Holliday’s recent climate change talk (if you attended it). If you use sources other than this video, be sure to cite (or at least mention) your source. And if you’ve already been doing some things to make a difference, try to identify what else you might be able to do to make some changes that can help reduce your carbon footprint! J
A.
adding CO2 to the atmosphere, turns up the planet’s thermostat
B.
removing CO2 from the atmosphere, cools things down
C.
whether CO2 is increased or decreased, there isn’t much of an impact on the planet either way
Explanation / Answer
1) option c, even if US cut down its emissions to zero, it will not impact much as China is emmiting far greater.However its per capita emissions is less due to huge population.
2) option b is correct. US emmit more than double of EU per capita.
3) False
