  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 CO2 • 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  CO2 – Temp graph • GGWS • Greenhouse effect should warm upper atmosphere first, not happening • Temp increase happens before CO2 • Sunspots are a better predictor of climate

  6. Evidence about CO2 • AIT • as CO2 increase, temp increases (monster graph) • GGWS • temp increase preceded CO2 by 800 years • ocean regulates CO2 • CO2 is only .05% of atmosphere • Water is 95% of greenhouse gases
