Ice Age Temperatures

The Kyoto Protocol states that we should spend billions of dollars to lower global temperatures by 0.02 to 0.28ºC. But just what is less than half a degree in terms of recent geological history? Let's look at the recent Ice Ages (there were four of them, separated by warming up periods). We know from evidence on the ground that ice sheets covered most of Britain, with the southern edge of the ice sheet running across southern England at its zenith. That would place southern England (represented by London) in the same position as the capitol of Greenland, Nuuk (used to be called Gothab). Nuuk enjoys a very different climate from London. The July maximum for London is 21ºC, for Nuuk it is 8ºC. That's a colossal 13ºC difference. If we simply say that, from the coldest period of a recent Ice Age to the Present Day the July maximum temperature could have risen as much as 13ºC, then the aims of the Kyoto Protocol do seem rather unimportant!

Greenland is, in itself, an interesting case history for studying global warming over the short term (in other words, over the time frame most doom-and-gloom climatologists consider to offer valid data). Do read this article for a succinct presentation on Greenland's recent history of cooling. Much of the published research referred to in this article was made by fanatic anthropogenic global warming advocates. I am sure that, if their results had indicated Greenland is warming rather than cooling, the media would have been very busy telling the world about it. As it is, the findings of this research work have gone largely unnoticed.
