Huge climate change worries -- see this thing written by a Woods Hole Oceanographic Institution scientist (not some freeze-dried food, gold, and guns kind of guy).

Excerpts :
********************************
Global warming could actually lead to a big chill in some parts of the
world. If the atmosphere continues to warm, it could soon trigger a
dramatic and abrupt cooling throughout the North Atlantic
region—where, not incidentally, some 60 percent of the world’s
economy is based.
**************************
And when I say “abrupt,” I mean: These changes could happen within
a decade, and they could persist for hundreds of years. You could
see the changes in your lifetime, and your grandchildren’s
grandchildren will still be confronting them.
*************************************
These shifts almost certainly involved changes in the ocean’s
circulation. There were shutdowns and restartings of the Ocean
Conveyor. These warm-to-cold transitions happen in about 3 to 10
years. The cold periods lasted for 500 to 1,000 years. Such
oscillations in temperature and ocean circulation have occurred on a
regular basis.
About 1,000 years ago, during a period of unusually warm
temperatures in the North Atlantic, the Norse established settlements
and vineyards in Greenland that would not be possible today. Those
settlements were abandoned about 500 years ago, when we believe
the most recent shutdown of the North Atlantic Ocean circulation
system occurred.
