How confident are you in the accuracy of climate models?
Do you think they’re generally accurate? Worthless? On what do you base this conclusion?
Here is one scientist’s take:
Many of the comments to previous blogs have stated that models are “just” a set of assumptions, and that the processes in the Earth’s climate are so complex that they defy our attempts to model them with any rigor. There are assumptions that are made when models are built, but those assumptions are not simply pulled out of a bag of magic tricks. In fact, arbitrary, unjustified assumptions are generally repelled from the modeling community because, first and foremost, the models need to describe some set of observations and the evolution of those observations, i.e. prediction. Most components of models are, just like my original modeling efforts, a representation of mathematical equations that rigorously describe the motion of the atmosphere. The idea that I and my colleagues would work from some potpourri of unjustified assumptions is, in fact, a bit offensive.

Today most of Greenland is a white land of permafrost put simply a white desert therefore how can the climate be warmer now as we know the Vikings named the land greenland because it was green and they could grow wine and food there?
Yet again the famous hockey stick chart link below doesn’t make any sense??
