Have you come across Piers Corbyn? He is reputed to be more accurate at long term weather forecasting than meteorologists, and accurately predicted the very cold weather in Europe at the end of 2010. For his forecasting he uses activity and cycles of the sun and moon, which he says dominate our weather patterns.
He claims that the famous “hockey stick” graph that “shows” that temperatures are increasing fast because of increases in carbon dioxide levels ignores temperatures in the middle ages that were higher than now. It also ignores the fact that despite rising carbon dioxide levels temperatures have been dropping over the last ten years.
There was a mini ice age a few hundred years ago when temperatures dropped by a few degrees Celsius and he predicts that the same will happen in 2035. There is some risk that this could trigger a full ice age, as we are overdue for one.
Interesting stuff! Why would (other) scientists falsify data? Take a look at Piers' Corbyn's Weatheraction website, his page on climate change which has some informative links, and an article summarising this from the Daily Telegraph of 19th December 2010.
