Global Warming Models

13 Apr 2011

Some people say that C02 does not cause warming - recent rising temperatures are due to natural factors such as solar cycles. Others think there is a lot less global warming than the propaganda proclaims - the data has been massaged  by various means to create an 'illusion' of rising temperatures. Still others accept C02 as a greenhouse gas and that as such it warms the planet - but the models labour under a false assumption and that is the idea of feedback. C02 causes greater warmth which causes more water to evaporate from the oceans - and adds to the warmth. At http://wattsupwiththat.com/2011/04/10/climate-models-go-cold/ is a post by scientist David Evans, a warmist who became alarmed at how the debate had developed - splitting hairs and sticking rigidly to certain assumptions. He says that global warming theory revolves around the idea that for each piece of global warming arising from increased levels of C02 three more pieces of warming kick in due to the extra moisture in the atmosphere. Hence, C02 warming is amplified by a factor of three in every climate model - but the models are not predicting what is actually happening in the real world.
