The history of global warming is a fact that global warming alarmists can't really explain. Warmer climate conditions than we now have existed during the Medieval Warming Period and during the Greek, Persian and the early Roman era. These temperature records are validated both by Sargasso Sea data and Greenland ice cores. Any theory of global warming that attributes most of the current warming to man-made causes must explain why the earth was warmer during these periods. I think variability of the sun is the main factor controlling global warming with man made influences mainly in the noise of the data. In fact particulate emissions may actually have a cooling effect as seen briefly after 9/11 when flights were grounded and the temperature rose. This may have been a coincidence. The Clear Sky Clock predicts clear weather in Salt Lake until this evening for the transit of Mercury. -----Original Message----- From: utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com [mailto:utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com] On Behalf Of slas@2nerds.com Sent: Tuesday, November 07, 2006 12:55 AM To: utah-astronomy@lists.xmission.com Subject: [Utah-astronomy] Climate chaos?
