Answer 2

There was an article in Scientific American in ( I think) 1993. It talked about 2 cycles for ice ages. one of 100,000 years and the other of 25,000 years. The 25,000 cycle was like out seasons. One major, one minor and the other two in between. I think the 25,000 was due to the earths axis.

Radiation cooling comes when you do not have many clouds. cooling leads to snow. snow reflects light. Temperature stability would be when incoming energy matches outgoing energy. too much reflection leads to cooling.

Is man causing global warming? Get the crooked politicians and junk scientists out of the way and let the scientist battle it out. What percentage of the greenhouse gases are man made? Has the temperature of the sun varied?
