Bomb the glaciers huh.. interesting...
I stay out of the global warming debate alot because as a scientist I dont study it, I am a geologist by trade, and get paid to do geology. I have theories on almost anything else, but they are basically my opinions and SWAGS (Scientific wild ass guesses) None of this is cited, I'm just pulling stuff I;ve read out my head, so dont quote me.
Spence is on the right track for once
There is more evidence that global warming is occuring than evidence to the contrary, much more.. To put politics aside and go past the US, the IPCC (Intergovernmental panel on climate change) has published numerous reports. their models and data change, the ultimate results change in scope, but the end result is the same; the earth is warming, sea level is rising etc.. This is 100's of scientists of varying affiliations coming to similar conclusions, thats a pretty strong piece of evidence in my book.
Are having an inpact on the earth as a species? I believe so. How much is just us amplifying an existing natural signal, and how much is just us? I have no clue.
Remember that yeah theories are theories, but I tend to believe the weight of evidence approach. I truly beleive that this administration is trying to bury and hide global warming as an issue.
Also remember that a few cold winters does not mean global warming is BS, in a lot of models some areas get colder with global warming. It's the average Temp of the earth, not just the north east....
