Well, another analysis of existing data suggests there is nothing unusual about sharp warm periods in climatic history. One of the prime theorems of climate hysteria is that we are in a period of exceptional warming caused by human emissions of CO2. Even assuming there is some warming currently (a proposition which is dubious to due various measurement and analytic tricks and urban heat effects), it appears to be well within historical natural variation. The hysterics claim human activities have caused a rise of 1.1 degrees Centigrade in the industrial era. So some real climate scientists decided to look and see whether, even if such a rise was an accurate statement, was it really unusual during the historical climate. An analysis of an existing Antarctic ice core record going back 800,000 years found that it was not. In fact, there were many, many instances of a 1.1 degree rise over the course of 100 years in that record looking back at our current interglacial period, which has lasted about 20,000 years. In fact 16% of all 100 year periods had such a rise. Interestingly, in earlier periods such a rise was very unusual, but that was during a period when obviously humans weren’t buring fossil fuels. Go figure. (SCE Article)
