What factors determine this potential?522How do volcanoes change the earth’s temperature?522-23Describe 3 natural sources of methane523How do nitrous oxide and water vapor get into the atmosphere naturally?524Compared to coal, what % of CO2 do oil and natural gas produce?524Why does burning fossil fuel upset the CO2 balance?524How does black soot cause a global warming positive feedback loop?524How does agriculture release methane and nitrous oxide?524How does deforestation influence global warming?524What greenhouse gases do landfills produce?525What does the IPCC do?525MAJOR CONTRIBUTORS OF METHANE N2O CO2526 Why does concentration of CO2 drop in the spring and rise in the fall?526What does Keeling’s CO2 data show?526DO THE MATH and show the work for Your Turn527Compare CO2 emissions in developed vs developing world528Describe the evidence that the earth has been warming since 1880.528What happened in 1880?529Describe how forams give indirect temperature measurements529How do ice cores give indirect evidence of global warming?530For over 400,000 years, CO2 levels never exceeded _________ ppm. The current concentration of CO2 is _________ ppm.531How have concentrations of methane and N2O changed since 1800?530How do shifts in Earth’s orbit cause global temperature changes?532Compare our avg temp with the average temp for the last 2000 years532What evidence shows that the earth’s increase in temp is due to greenhouse gases and not an increase in the Sun’s radiation?533Why are there different predictions for global temperatures in 2100?534By 2100, how much hotter is the world going to be?534-35Describe some of the feedback systems that affect global warming535Describe predicted effects of global warming on polar ice caps, glaciers and permafrost536Describe predicted effects of global warming on sea level537Describe predicted effects of global warming on heat waves, cold spells, precipitation patterns and storm intensity538Describe predicted effects of global warming on ocean currents538Describe predicted effects of global warming on wild plants and animals539Describe predicted effects of global warming on humans539Why is global warming controversial?540-41Explain what the Kyoto Protocol, 1997, did.541Carbon sequestration =543Arnold Schwarzenegger’s environmental claim to fame = ................
