Victor, your 2nd link referred more specifically to man-made global warming. It included strong references to the IPCC.

I'm not a scientist. But I'm enough of a budding historian that I remember things. Like the IPCC and the admission by doctors on the panel of data fraud. (They used untested/unreviewed data to try to include policy makers/politicians, and they knew they were doing it at the time)

Additionally, many reports from the "man-made" global warming camp have tried to downplay (or ignore) the margin of error in their studies.
