Note: Original peer reviewed paper ref given below: Extremely interesting "new" theory that can explain the last 100 years' or so climate change events in terms of "synchronised chaos" rather than "anthropogenic" causes. http://www.dailytech.com/Major+New+Theory+Proposed+to+Explain+Global+Warming/article8450.htm Especially useful are the readers' comments following the article, with a number of apparently well qualified people making detailed comment. The main point of this to me is NOT that someone has come up with a "new explanation for Global Warming" (and they probably haven't in isolation, and they probably don't claim to have) but that it further demonstrates the vast number of factors which are and may be involved and demonstrates how complex the subject is and how dangerous it is to try and cut and dry the arguments and subject. (That said, my original "5 short sentences" were an attempt to make this point and this further demonstrates the points, along with the truly vast body of information available on the web.
