From this article , titled " Greenland's Ice Sheet Is Slip-Sliding Away":
"From cores of ancient Greenland ice extracted by the National Science Foundation, researchers have identified at least 20 sudden climate changes in the last 110,000 years, in which average temperatures fluctuated as much as 15 degrees in a single decade."
Sudden temperature changes have happened scores of times before, without humans to blame.
That's a truth that's inconvenient for Gore and the in-liars he represents. (He kept referring to any dissenters as "out-liers" on a TV interview "There will always be outliers that refuse to learn the truth, the issue has been decided in the scientific community"....that term really bugged me because of its "liar" connotation. A-hole.) The thing is, I agree the planet shows signs of warming over the past 100 years. But I think it's not all bad news....only 1 degree despite burning half the planet's fossil fuel? Great! Would it be better for humans for the planet to be cooling? No. We've been fortunate with the climate for the past 10,000 years, but there are no guarantees for what the future will hold, no matter what we do.
