HW 7 Carbon Footprint & Global Climate Change Part 1. Carbon Footprint Calcula2on Most scien*sts believe that global warming has already begun and it is increasing. It can be dated back to the industrial revolu*on, which began during the mid-1700's. Since this period of *me, humans have contributed to climate change by expelling carbon dioxide into the atmosphere, most commonly by driving vehicles. There are a number of really significant and severe consequences that have been exacerbated by these addi*onal greenhouse gases in the atmosphere, include warming temperatures, glacial ice mel*ng, sea level rise, and ocean acidifica*on, to name a few. We will discuss these consequences in class. For this assignment, I would like you to calculate your carbon footprint by going to the following website: hJp://www.nature.org/greenliving/carboncalculator/ The website will ask you to input informa*on about the things that you use every day. From there, it will calculate your es*mated greenhouse gas emissions and compare you to the average person. Sample: e l p S m a HW 7 Carbon Footprint & Global Climate Change Carbon Footprint Conclusions: 1. Answer the ques*ons in the Home Energy, Driving & Flying, Food & Diet, and Recycling & Waste tabs. Calculate your carbon footprint in tons of CO2 eq/year and write the value below: 2. Which of the tabs/categories represents your largest contribu*on of carbon? 3. Where can you reduce your carbon input the most? Name the category and a specific ac*on or strategy you can take. Carbon dioxide (CO2) can remain in the atmosphere for hundreds to thousands of years once it is released into the atmosphere. It has been es*mated that 20-30% of human CO2 emissions is absorbed by the world’s oceans. 4. Calculate (in tons of CO2 eq/year) how much of your carbon contribu*on is absorbed by the ocean, assuming 25% of the carbon you contribute to the atmosphere is absorbed by the ocean. HW 7 Carbon Footprint & Global Climate Change Part 2. Learning about Global Climate Change Next, we’re going to explore some current climate data. I’ve selected some data from the following website: hJps://www.ncdc.noaa.gov/temp-and-precip/state-temps/ to help you answer the ques*ons and create your graphs. 5. The above graph is for California from 1895-2018. How would you describe the trend of this graph? 6. In 1895 what what was the average temperature for California? In 2017? 7. How much has the average temperature risen in California between 1895 - 2017? HW 7 Carbon Footprint & Global Climate Change Next, let’s explore the temperature trends in the US over the last few years. Below I’ve included a map that shows how temperatures have changed annually in the US. 8. Which areas of the US have warmed up the most? HW 7 Carbon Footprint & Global Climate Change Last year I recorded some numbers based on maps from the NOAA (Na*onal Oceanic and Atmospheric Administra*on) website, so that we can use it for this assignment. I’ve included the results below. Use the data provided to graph the results. Decade # of US States # of Contiguous US States with Higher than Average Temperatures 50 14 1901-1910 2 45 1911-1920 2 40 1921-1930 20 35 1931-1940 42 1941-1950 34 1951-1960 41 1961-1970 5 1971-1980 10 1981-1990 42 1991-2000 50 2001-2010 50 2011-2014 # of US States (contiguous) 1895-1900 30 25 20 15 10 5 50 0 1895-1900 1911-1920 1931-1940 1951-1960 1971-1980 1991-2000 Time 9. In the space below, please summarize what you’ve found by graphing this data. In the US, what has happened to the overall temperature? Have any states been lee unaffected by this? 2011-2014 ...

1. Answer the questions in the Home Energy, Driving & Flying, Food & Diet, and
Recycling & Waste tabs. Calculate your carbon footprint in tons of CO2 eq/year
and write the value below:
10
4

= 2.5K CO2

2. Which of the tabs/categories represents your largest contributed*on of carbon?
Driving & Flying
3. Where can you reduce your carbon input the most? Name the category and a specific
ac*on or strategy you can take?
Concentration of carbon dioxide in the atmosphere can be easily changed in the
category of home energy through change of diet. This includes consuming foods that does
not require a lot of energy when cooking hence producing less carbon dioxide from
combustion. Therefore, the strategy of changing the diet can be easily applied to reduce
carbon dioxide accumulation in atmosphere.
4. Calculate (in tons of CO2 eq/year) how much of your carbon contributed*on is
absorbed by the ocean, assuming 25% of the carbon you contribute to the atmosphere
is absorbed by the ocean.
