Quote of the day

Paleoclimatic information supports the interpretation that the warmth of the last half century is unusual in at least the previous 1300 years. The last time the polar regions were significantly warmer than present for an extended period of time (about 125,000 years ago), reductions in polar ice volume led to 4 to 6 metres of sea level rise.
