NSF issues solicitation for decadal and regional climate prediction using Earth Systems Models

Green Car Congress

NSF anticipates funding of $35,000,000 to $39,000,000 in FY 2012 and FY 2013, pending availability of funds, to be awarded to an estimated 7 to 12 projects. NSF said that is chose a time span of several decades because within this timeframe modeled climate change responses appear to be insensitive to CO 2 forcing scenarios.
