Document Summary
Final exam: monday, december 11th, 9:40-11:40 no math equations. Carbon dioxide (82%: 16 17 tons of carbon dioxide are being released per person each year. Climate is weather averaged over time over broader geographic areas: usually averaged over 30-yr periods. Weather is the state of the atmosphere at a particular time and place. Nearly all of the air is made of oxygen (o2) and nitrogen (n2) in which two atoms of the same element share electrons. Doubling co2 would add 4 watts to every square meter of the earth, 24/7. Direct measurements of the output of human activities: fossil fuel usage, forest fires, land use changes. Ratio of carbon isotopes in plants and fossil fuels are different than in the atmosphere. Keep track of energy and its movement in land, oceans, and atmosphere. Coupled with socio-economic predictions about how nations will use fossil fuels in the coming century.
