As the last threads have devolved into misinformation, I have had trouble keeping up with all the garbage thrown about. So, here goes another thread on Global Warming, based on my watching 2 hours of C-SPAN coverage of the IPCC testimonials (working group 1) in front of the House science committee. First, I encourage anyone still unclear about what the concensus is on climate change to go here . Its obvious that many here are still misinformed. I admit, I was less convinced of the warming argument until recently, but like many of the other skeptics in the room (mostly R), I am fully convinced now. What a coincidence that many of the skeptics claims were clearly and concisely debunked by the scientific panel on the very day we were bantering it about here. The conclusions, in summary are: http://democrats.science.house.gov/Media/File/Commdocs/hearings/2007/full/08feb/hearing_charter.pdf This was by far the most informative hearing I've ever witnessed our Congress holding! Personally, I also found the answers to several questions I posed to skeptics here, over the past few weeks of this debate. Specifically: 1) the US per capita CO2 output is 10 times that of China 2) the "hockey stick" analogy applies well to CO2; that is, current CO2 concentrations are unprecedented in 650,000 years of earths history 3) CO2 is the #1 greenhouse gas; oddly, no mention of 'water vapor' as a greenhouse gas 4) Methane is a huge contributor and New Zealand is a major culprit (with their sheep) and they are working on feedstocks that reduce methane output 5) There was no scientific consensus in the 70s that the earth was, in fact, cooling, in spite of what some here have claimed. It was in the press, but the scientific community never came to this conclusion as evidenced by the NAS(This was pointed out by a Republican, FWIW) But the most interesting finding yesterday was this: Republican Dana Rorhabacher (sp.?) from CA is an absolute nutjob, looked like he spent the night before binge drinking, and threw all the same flimsy arguments at these scientists as many here do. I wonder what % of contributions he takes from petro lobby. Sensenbrenner is going to die soon as is obvious from his apparent high blood pressure- his head almost exploded as he was witness to scientific facts. He almost lost it...then, simply left. (Good boy, get out of the way and let the adults handle this) ..and finally, those many Republicans that stayed for the entire hearing all said they came away with the same opinion- they were convinced. They made their opinions clear and were open to bipartisanship. They were great. My takeaway was very encouraging. Now, any misinformed skeptics still want to debate this? Fire away.
