myfriend,
No lies. The earth got a lot warmer between 1880 and 1940. It then cooled a bit between 1940 and 1980 hence the concern about cooling. (And that was 30-40 years ago, not 25.) 1980 to 2000 saw the most rapid increase in global temperatures ever seen; that rise may have leveled off since then. Global warming is a fact, not a lie, and there is no dispute whatsoever among scientists or anyone else who has looked at the data (and you can find some with a quick internet search); the disputes are as to the degree to which human activity is responsible and what should be done about it. And anyone who rejects scientific facts has nothing to add to scientific discussions.
