Tackling Human-Relevant Climate Change. (March 23, 2010)
Here is a quote in its entirety from the March 22, 2010 ScienceNow:
Three
federal agencies
announced the launch Monday of a joint program to predict
climate change and its impacts on local scales over a few decades, information
that decision makers will need to adapt to the inevitable. Obtaining such detail
is an ambitious goal; computer models today yield seemingly reliable predictions
of temperature and precipitation on continent-spanning scales at best. Under the
Decadal and Regional Climate Prediction Using Earth System Models (EaSM)
program, the National Science Foundation and the U.S. Departments of Agriculture
and Energy will kick in a total of $50 million a year for 5 years.
"People live in regions, not on the global mean," said NSF Director Arden Bement in announcing the initiative. "Our experience of climate change is always local." To move from the continent- and century-scale to the Midwest- or Northwest-scale and decade-scale, scientists from computer specialists to geoscientists to biologists will draw on the "petaflop" calculating power of current supercomputers, said Bement. At the same time, understanding of climate change, especially the chronic problem of the role of clouds and aerosols, must be improved as well, he conceded.
