There has been something of a flurry of posts around the sceptic blogosphere about climate models and I wonder if this may continue to be a theme in coming weeks after James Hansen's recent admission that climate models are getting ocean heat uptake and the mixing of heat in the ocean wildly wrong.
This story is covered in layman's terms here by Anthony Cox and David Stockwell:
The Earth’s energy balance is the most important measure of anthropogenic global warming [AGW] because it shows whether energy is leaving or accumulating.
Among 52 dense pages of science, Hansen reports on two experiments from the last eight years that call for major revisions to the GCMs.
This is definitely a "read the whole thing" kind of article.
Put alongside the poor performance of the models against observations in recent years do we really have a watertight scientific case that demands a policy response?
