The distributed computing project climateprediction.net is working through a series of regional climate Weather@Home models through the BOINC system that is ran across the world to run their climate models. Currently of the models being distributed is one of the 2013/2014 winter floods across the UK and Europe. (Disclaimer, that model is currently running on my computer right now). They run different ensembles of the time period with known CO2 levels and other hypothetical levels if the CO2 was lower (fewer man-made emissions). The results are still in progress, they should be interesting, but they do have some results out already.
Other areas focused on are the western United States for drought, Australia/New Zealand for Heat/Drought, South Africa on human interaction, Southwest Asia for the Indian Monsoon, and a continental model for Africa which is not well known in modeling circles.
These models could be huge in helping with insurance/reinsurance catastrophic finance models, the greater economic development of the areas, and mitigation of current problems where you would start with a given meteorological model based on many repeat runs and plan around it into the GIS/Geomatics arenas. Some people will only see profit, which there will be some but the greater common good is helped by understanding the climate better.
