I can prove the end is near.... I agree with most of what Hortlund wrote.
Shuckins, good points too sir. Did you both note that you agreed on the human effect on global warming, that is that THERE IS a human effect. The only differentiation is the degree.
OTOH Shuckins you wrote: Man-made pollutants are undoubtedly playing a part in global warming. These reports suggest that climatologists do not, yet, know exactly how significant that part is.
soon after writing this: the ability to quantify the human influence on global climate was limited... Nevertheless, the report also concluded that the balance of evidence suggest a discernible human influence on global climate.
Does anybody else find the last two statements in that summary to be contradictory?
First you say it is contradictory, then you say it is undoubtably true. Go figure.
