Global Warming is real, get over it.
"Temperatures after ice-ages will rise, but they do not normally rise by almost a degree in 150 years! It is an incredible rate of change (on a global scale) and points to something much more servere than 'only a little temperature rise'." 1/3 of degree in 150 years actually. And you know why? Krakatoa, that big volcano in the Pacific, exploded in the 1600s, and this spewed ash into the air. Soon afterwords, global temperatures plummeted, drastically. (History Channel) Obviously a drastic rise is needed to counteract that sudden drop. "I've got no idea what GISS is, but i'm not sure there entirely accurate. The British Antarctic Survey has found the antarctic peninsula to be "one of the fastest warming parts of the planet". http://www.antarctica.ac.uk...; GISS is probably the most accurate temperature collection agency in the world. They monitor the southernmost temperature collection system in the world, at least that has been keeping records for more than 100 years, and the average rate of change at that temperature station has been -.1 degrees Centigrade. The data that most proponents of GW cite is simply the rate of change between the first point of data, and the most recent. However, that is a statistically incorrect method of analyzing data. Go to NASA if you want to find GISS, or read State of Fear, by Michael Crichton, he has the link in the appendix. "The temperature is rising...this is the only way to begin a shift in the way the climate works." http://en.wikipedia.org... Graph of global temperatures since 450000 years ago. Notice the current temperatures are by no means anomalous. "I will leave you to suppose that, hyperthetically, you had to imagine a world where climate change was happening... what would you look for? A sudden rise of temperatures? Yearly 'hottest year ever' awards? Polar ice caps beginning to melt? Hmm the reality isnt that far away is it." Anomalies in long term temperature changes, upper atmosphere temperature shifts, need I say more? My opponent dropped my points that the upper atmosphere has stayed constant in temperature, contrary to what the greenhouse effect would produce if it were causing warming, the fact that greenhouse gases have not increased significantly enough to change temperatures, and that current temperatures are not anomalous.
