Climate Change vs. Global Warming

Global Warming Long-term rise in Earth’s

temperature (a few degrees)

Increase in greenhouse effect

Anthropogenic= caused by people & their activities

Climate Change Overall change due to GW Melting ice caps, glaciers Tundra thawing Sea level rise Biomes changing

Greenhouse Gases H20 Water vapor CO2 Carbon dioxide CH4 Methane N2O Nitrous oxide O3 Ozone CFC’s Chlorofluorocarbons (man-made) Without them, Earth’s temperature would be

an average of 59 degrees F colder

Burning fossil fuels Deforestation

CFC’s Refrigerants Propellants

UN Climate Change Conference Occurring 12/7-12/18, 2009 in Copenhagen,

Denmark Essentials for an international agreement:1. How much are industrialized countries

willing to reduce GHG emissions?2. How much are major developing countries

like China and India willing to do to limit the growth of their GHG emissions?

3. How is the help for developing countries going to be financed?

4. How will that money be managed?
