  14. US Cost of energy($ = US dollars; ¢ = 0.01 US dollar) Plug-in Hybrid: more expensive than $15/gallon gasoline! (but less carbon dioxide)

  15. Greenhouse Gases

  16. Are the fears all based on complicated computer calculations? 1896 Arhennius 1958 Revelle 1979 MacDonald 2007 IPCC

  17. Greenhouse effect(car in the parking lot effect)

  18. This is global warming: Warming last 158 years + arctic sea ice & sea level

  19. In last 100 yrs, sea level rose 8 inches

  21. Antarctica losing ice mass Antarctic Ice Sheet Losing Mass, According to CU-Boulder Study March 2, 2006 University of Colorado at Boulder researchers have used data from a pair of NASA satellites orbiting Earth in tandem to determine that the Antarctic ice sheet, which harbors 90 percent of Earth's ice, has lost significant mass in recent years. The team used measurements taken with the Gravity Recovery and Climate Experiment, or GRACE, to conclude the Antarctic ice sheet is losing up to 36 cubic miles of ice, or 152 cubic kilometers, annually. By comparison, the city of Los Angeles uses about 1 cubic mile of fresh water annually. "This is the first study to indicate the total mass balance of the Antarctic ice sheet is in significant decline," said Isabella Velicogna of CU-Boulder's Cooperative Institute for Research in Environmental Sciences, chief author of the new study that appears in the March 2 online issue of Science Express. The study was co-authored by CU-Boulder physics Professor John Wahr of CIRES, a joint campus institute of CU-Boulder and the National Oceanic and Atmospheric Administration. The estimated ice mass in Antarctica is equivalent to 0.4 millimeters of global sea rise annually, with a margin of error of 0.2 millimeters, according to the study. There are about 25 millimeters in an inch. The most recent Intergovernmental Panel on Climate Change assessment, completed in 2001, predicted the Antarctic ice sheet would gain mass in the 21st century due to increased precipitation in a warming climate. But the new study signals a reduction in the continent's total ice mass, with the bulk of loss occurring in the West Antarctic ice sheet, said Velicogna. Researchers used GRACE data to calculate the total ice mass in Antarctica between April 2002 and August 2005 for the study, said Velicogna, who also is affiliated with the Jet Propulsion Laboratory in Pasadena.
