Burning fossil fuels Green house gas CO2 Mining coal and oil Slide 5: Population More food, more methane, more burning of fossil fuels Manure Transportation Slide 6: Effects of Global Warming Rise in sea level Increase of ocean temperature Decrease of snow cover Slide 7: Impact on Animals Birds laying eggs earlier Plants are flowering earlier Mammals are getting out of hibernation sooner Slide 8: Melting of ice in Greenland and Antarctica Increase in agriculture Water reservoirs drying up In humans, heat-related illnesses and increased breathing problems Chance of Malaria Extreme weather Slide 9: Personal Contribution to Global Warming I contribute to global warming by driving a car daily around campus and also driving home every other weekend.
