Springtime for Santa

Went on a fine bike ride yesterday. Temperature in the low 50s, no wind, plenty of sun low on the horizon. Saw some deer, swans, ducks, thrushes. It's a great year for winter wheat.
I've written how we have just had the warmest September, October and November ever since the invention of the thermometer, and December is way above average-- the only part of Sweden with snow on the ground is Lapland. I have started to think of this winter of a preview of the coming climate. We have had a lot of mist and fog lately, caused by an elevated ocean surface temperature.

It has been warm and dry here too.
I thought Europe would enter into a deep freeze due to global warming... when the ice sheets melt and disable the gulf stream?

Oh don't I know it-- Europe gets 1/3 of its heat from the gulf stream. There is a guy named Andrew Marshall who initiated the Star Wars program at the Pentagon. In 2003 he commissioned a study of the implications to national security of the collapse of the gulf stream. The study predicts a drop in temperature of 5F for Europe and N. America, and a 3.6F increase for Australia, S. America and S. Africa. That's how much heat the gulf stream carries north from the equator. The gulf stream has stopped in the past-- 12,000 years ago when an ice dam broke and a lot of N. America started to drain through the St. Lawrence River instead of the Mississippi. Then 8000 years ago when Lake Agassiz drained into Hudson's bay. The Greenland ice cap has enough water to do the job, and it is melting. Just as important, rainfall is increasing at high latitudes as a consequence of global warming. All this freshwater, rain and meltwater, is bad. The climate system is chaotic.
