1. Global Warming POV’s An Inconvenient Truth vs. The Great Global Warming Swindle

2. Is Global Warming Happening?  AIT –yes –a lot  GGWS –yes –½ degree so far

3. Cause of Global Warming  AIT –anthropogenic CO 2  GGWS –sun

4. Evidence for Global Warming  AIT –Glaciers are melting –Permafrost is thawing –Hotter years, drought –More storms –Increased extinctions, coral reefs  GGWS –Just natural fluctuations –Has happened MANY times in Earth’s history –We’re coming out of the Little Ice Age

5. Evidence for Greenhouse Effect  AIT –Ice core data  CO 2 – Temp graph  GGWS –Greenhouse effect should warm upper atmosphere first, not happening –Temp increase happens before CO 2 –Sunspots are a better predictor of climate

6. Evidence about CO 2  AIT –as CO 2 increase, temp increases (monster graph)  GGWS –temp increase preceded CO 2 increase by 800 years –ocean regulates CO 2 –CO 2 is only.05% of atmosphere –Water is 95% of all greenhouse gases
