Other Tink posted a talk a while back by Nobel laureate Freeman Dyson, questioning global warming...which I had accepted as proven. However, I had a difficult time finding the corroborating science that to me was convincing.
Well, I finally DID locate that convincing science, but still had questions about the data; because I know from experience you can misuse data (often unwittingly) to fit an agenda.
THEN I found a source saying that of the 97% of scientists who agree on global warming, their unanimity is not as complete as it seems...that thousands of e-mails were coming in to IPCC*, questioning how the data was processed.
THAT was enough for me; I now have doubts we can consider global warming as proven.
I am not even sure our scientific methodology is capable of addressing such a question. I still have ONLY A HUNCH that global warming IS truly happening, but now doubt we should focus on that so intensively.
It does seem clear that we ARE capable of rendering the planet unfit for human habitation, and imo, reversing that is where our efforts should go...a subtle tweak, but more realistic?
