  3. What is Climate Change?? Change in Air Temperature from the average of the 1950’s-1980’s compared to the 1990’s

  4. Earth Moon Green House Gas % in the Atmos 5 0 Distance from Sun (millions of km) 149 149 Day/Night Temperature Range (oC) 107/-153 26-17 Average Temperature (oC) 21 -23

  5. Mercury Venus Green House Gas % in the Atmos <1 95 Distance from Sun (millions of Km) 58 108 Daily Temperature Range (oC) 420/-150 450/450 Average Temperature (oC) 400 450

  6. Poll Question According to the historical data, is climate change cyclical? √ Yes XNo

  7. 400,000 Years of Antarctic CO2 and Temperature Change Source: Climate Change Impacts on the US, NAST, 2001

  8. Northern Hemisphere Carbon Emissions Source: Climate Change Impacts on the US, NAST, 2000

  9. Atmospheric CO2 Concentrations Source: Climate Change Impacts on the US, NAST, 2000

  10. Northern Hemisphere Surface Temperature Source: Climate Change Impacts on the US, NAST, 2000

  11. “Simulations of the response to natural forcings alone … do not explain the warming in the second half of the century” SPM Stott et al, Science 2000

  12. “..model estimates that take into account both greenhouse gases and sulphate aerosols are consistent with observations over this period” SPM Stott et al, Science 2000

  13. What other Factors could increase or decrease Global Warming in the long and short term? [Type in the chat]

  14. Let’s Pause Two Minutes for Questions from the Audience

  15. Section II How is/will climate change be impacting you? Regional impacts

  16. IPCC world CC map

  17. Alaska and Canada

  18. Poll Question Which of the impacts of climate change might have a positive, short term effect? Forest Production Insects Sea Ice thinning

  19. Change in Forest Productivity from 1982 to 1999 Nemani et al., Science June 6th 2003

  20. Insects

  21. Spring bud-burst dates for Aspen in Edmonton

  22. The increase in growing season length over the last 50 years averaged for eight stations in Alaska having the longest and most consistent temperature records.

  23. Can you think of other potential long and short term impacts of climate change for this region? [Type in the Chat]
