The sun sets in the high Arctic

It is a beautiful late September and in the high arctic the sun is setting. The great freeze has begun and we can all put this subject back into hibernation until the spring. Unbelievably, we have all lived through the unthinkable. The legendary Northwest Passage was open for weeks this year for the first time. The North East passage almost opened for one short week also.

I am also told that South Atlantic sea ice reached a record breaking maximum. This suggests a disturbing hypothesis. That the deep sea circulation system is able to pulsate surplus heat or lack thereof between the poler regions through the Atlantic on a centuries long cycle. The five century long little ice age we are now exiting is only one example. It certainly explains the origins of the little ice age as I suggested in an earlier post.

If such a long cycle exists, and the little ice age is the best evidence, then our attempts to link global temperatures to CO2 content are even more spacious than I thought. Mother Earth has one hell of a correction device.

Have a good weekend.
