Read here. Climate models are purported to be able to predict the climate and major climate components. These climate model claims are made mostly by government sponsored scientists who are attempting to sustain or increase their government funding. Their research grant greed and personal financial security cause these "scientists" to make false claims about climate model capabilities.
The most recent example of this gross misinformation campaign is the bogus claim that climate models can predict the ocean oscillation climate pattern known as ENSO. If these models had an iota of successful prediction capability, they would have predicted the significant La Niña condition that currently exists. Instead, as the image below indicates, all the climate models failed to accurately predict this last November (2009). (click on image to enlarge; image source)
