The problem that is often ignored is that the earth cooled from 1940 to the late 1970's. This has never been adequately explained by the models. -----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 Chuck Hards Sent: Wednesday, November 08, 2006 11:11 AM To: Utah Astronomy Subject: RE: [Utah-astronomy] Climate chaos? Nobody disputes prehistoric climate change or the increasing solar output over time. I feel that introducing these facts misses the point. What the debate is about, as I understand it, is that the current warming trend has happened far faster and to a greater degree than any historical or pre-historic change for a given amount of time, and it clearly coincides with the huge spike in greenhouse gas emissions of 20th-century industrial growth. ________________________________________________________________________ ____________ Want to start your own business?
