Oak Ridge Supercomputers Provide First Simulation of Abrupt Climate Change

Here's a great article about accomplishments regarding climate simulation with a Supercomputer where I work (though I am not involved in this particular activity).

OAK RIDGE, Tenn., July 16, 2009 — At the Department of Energy's Oak Ridge National Laboratory (ORNL), the world's fastest supercomputer for unclassified research is simulating abrupt climate change and shedding light on an enigmatic period of natural global warming in Earth's relatively recent history. The work, led by scientists at the University of Wisconsin and the National Center for Atmospheric Research (NCAR), is featured in the July 17 issue of the journal Science and provides valuable new data about the causes and effects of global climate change....
