The model considered circumstances not fully included in previous models, such as snow which reflects energy from the sun back into space, and mountain peaks, which can stand in the way of travelling weather fronts.

But they still haven't modelled the effects of increased cloud cover that they expect. Oh yeah, I forgot, that little factor would cause cooling so we don't want to model that....

Why is it always a "climate model."

You never see the global warming guys say "based on the actual climate of the last 50 years ..." They point to a rise of 1 deg F in the average temperature of the earth (like that can actually be measured) but that still depends on where you start from.

Start the record in 1893, just after Krakatoa blew up and there is a large increase. Start in 1934 at the height of the depression and drought and you get a different result.
