GLOBAL WARMING DEBATE SUMMARY
Paul H. Carr, Ph. D., debated with Prof Laurence I. Gould on Saturday, Nov 19. 2011 at the New England Section of the American Physical Society Meeting at the University of Massachusetts at Amherst.
Dr. Carr's PowerPoint talk was entitled, Data Supporting Anthropogenic Global Warming: Balancing Economics and Ecology It is available on his web page

Prof Laurence I. Gould' talk was Anthropogenic “Global Warming” —
Illuminating some of its Scientific and Methodological Flaws. His web page http://uhaweb.hartford.edu/lgould/ includes "GOULD PRESENTATION," is almost the same PowerPoint he used for the debate.
SUMMARY OF HUMAN INFLUENCE ON GLOBAL WARMING
-Correlation of carbon dioxide, C02, and temperature increases since the beginning of the industrial era.
-Carbon dioxide increase is from burning fossil fuels (Carbon Dating).
-Increased greenhouse gases (C02) blanket and warm the earth’s surface, allowing less heat to reach the stratosphere, which is cooling.
-Solar irradiance has not increased since 1940 (sunspot cycles).
-Present CO2 level of 390 ppm is 31% higher than in the last 800,000yrs.
- Extrapolates to 900 ppm by 2100.
-When CO2 was 900 ppm, 51 Million years ago, earth was ice-free, sea levels 100s of feet higher.
-Present sea levels are projected to increase 2.5 – 6 ft by 2100.
- Without the radiative forcing of noncondensing CO2, the terrestrial greenhouse would collapse, plunging the global climate into an icebound earth state
