Weblog On The Resilient Earth Titled “Seven Climate Models, Seven Different Answers” By Doug J. Hoffman

There is a very informative summary of a number of the issues raised on my website in a post on weblog The Resilient Earth by  Doug L. Hoffman on june 16 2009.  The post is titled

Seven Climate Models, Seven Different Answers 

The post is worth reading and their website should be bookmarked. The conclusion of their weblog states

“Earth’s climate system is amazingly complex and modeling is fraught with pitfalls and danger for even the most experienced computer scientists. No climate model predicted the current downturn in global temperatures, though many are now scrambling to predict possible decades of unchanging or cooling climate “within the general warming trend.” Still, climate science remains enthralled by its computerized playthings. I have to echo Professor Pielke’s question, how many years of wrong results are necessary before we reject the IPCC reports and the models they are based on?”

The plan to regulate CO2 by the EPA, and the intent of Congress and the President to introduce a “cap and trade” program for carbon emissions, in order to regulate climate, should require that the basis for these policy decisions be scientifcially robust.  It is essential to include all human climate forcings on climate (including land use/land change effects) in assessing the ability of their plans to actually alter climate.  They clearly have ignored doing this, and we will have a costly yet ineffective climate policy as a result.
