Zoltan, Global warming and ice ages are not as far apart as you think. An average increase in global temperatures evaporates a lot more ocean water. If this excess precipitation occurs as snow, an ice age could be triggered as more sunlight is reflected back into space, creating a domino effect where there is not enough warmth in the Summer to melt all of the snow. What we are seeing is extreme swings in temperature and precipitation. What is causing it is not certain, but the consensus among scientists its that we are causing at least some of it. It is important to know the answer, and we need to study the issue further, but I think that it would be wise to start doing something now.

Greenland was not green when the Vikings settled there. The ice sheets are very thick and hundreds of thousands of years old.
