Climate Prediction modeling! (Score 1)

I'm pretty sure these guys - http://boinc.berkeley.edu/ - are using the CPU for their modeling, but why not the GPU? I think the way the Climate Prediction project (http://climateprediction.net/) works is the software crunches numbers for a while (e.g. how did the weather progress on the morning of June 3, 1811) and then takes a snapshot of the result at periodic intervals. Seems just right for a graphics card, given its modeling strengths and download/upload constraints.
