A comprehensive look at global warming, delivered to the University of Wisconsin's School of Forestry

1. Global Warming: Science, Economics, Ethics Iain Murray UW-Madison Hamilton Roddis Lecture Kemp Natural Resources Station August 18, 2009

3. The Science What is the evidence telling us?

4. The Temperature Record

7. Isn’t There Less Arctic Sea-ice?

8. 2008 + 700,000 sq km > 2007

9. So What About Those Polar Bears?

10. Warmer than it was in 1880

11. But colder than it was in 1934

13. What’s Happening Globally?

14. Is This Unusual? What do we know about previous temperature variations?

16. Glaciers melting ...NOT since SUVs , but since the end of the LIA ! See e.g., Frtiz Range, since 1865 Or, Glacier Bay, since 1860

21. Symbolism 16th century: Breughel Winter Scene with Bird Trap

24. The Hockey Stick IPCC 2001

25. The Data Re-analyzed Burger & Cubasch 2005

28. Sea-level Rise?

29. Ocean Temperature?

30. Sea-ice Extent in Antarctic?

31. Hurricanes and Cyclones?

33. Scientific Understanding is Lower than You Might Think

34. So now we’re told of “faster than predicted” warming…even as it cools CO2 rising but global temps falling (forget sun, clouds, oceans)

35. Isn’t CO2 Increasing Faster Than Anticipated?

36. How much more warming can we expect? Probably less than they tell us

37. IPCC projections – NOT predictions

38. The Models Are Essentially Linear

39. Data – the Modeler’s Burden

40. Models vs Data

42. So What Do We Hear?

47. The Economics What will emissions reduction cost the US and the world?

50. Changes in Net GHG Emissions 1 2000-2006 from 17 Major Economies 1 Includes emissions of carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, and perfluorocarbons, as well as emissions and removals of carbon dioxide, methane, and nitrous oxide from land-use, land-use change and forestry activities. ** No UNFCCC data available for time period; 2001 through 2005 IEA data used.

52. How Expensive is the Gore Plan?

54. Massive Effort Needed to Meet Emissions Goals Source: Clarke, L. et al. 2006. Climate Change Mitigation: An Analysis of Advanced Technology Scenarios . Richland, WA: Pacific Northwest National Laboratory. Cumulative global emissions reductions ranging from about 1,100 to 3,700 gigatons of CO 2 equivalent would be need over the course of the century to meet a range of atmospheric concentration goals (450 to 750 ppm). 1st GtC Avoided CO 2 Emissions (GtCO 2 /yr) Cumulative Emissions Cumulative Avoided Emissions Unconstrained Emissions Scenario CO 2 Stabilization Scenario ≈ 1,100 to 3,700 gigatons of cumulative CO 2 emission reductions will be needed to meet a range of stabilization scenarios (≈750 ppm to 450 ppm).

55. How Big is One Gigaton* of CO 2 ? *Gigaton = 10 9 Metric Tons Install 1,000 sequestration sites like Norway’s Sleipner project (1 MtCO2/year)—Only 3 sequestration projects of this scale exist today. Geologic Sequestration Build 273 “zero-emission” 500 MW coal-fired power plants—Equivalent to about 7% of current global installed coal-fired generating capacity of 2 million MW. Coal-Fired Power Plants Convert a barren area of about 4,800,000 km 2 —Equivalent to about 2 times the size of the United Kingdom. Biomass Fuels from Plantations Install capacity to produce 273 times the current global solar PV generation instead of new coal-fired power plants without CCS. Solar Photovoltaics Actions that Provide One Gigaton CO 2 / Year of Mitigation or Offsets Technology Convert a barren area of about 900,000 km 2 —Equivalent to more that the size of Germany and France combined. CO 2 Storage in New Forest Install capacity to produce 14 times the current global wind generation capacity (about 74 GW) instead of new coal-fired power plants without CCS—Equivalent to more than 1 million 1 MW wind turbines. Wind Energy Deploy 273 million new cars at 40 miles per gallon (mpg) instead of 20 mpg (or at 14 km/L instead of 7 km/L). Efficiency Build 136 new nuclear power plants of 1 GW each instead of new coal-fired power plants without CCS—Equivalent to about one third of existing worldwide nuclear capacity of 375 GW. Nuclear
