First simulation of 'abrupt climate change'

Oak Ridge National Laboratory today announced the lab's supercomputers, including Jaguar (the second-fastest machine in the world) were used to simulate abrupt climate change and provide valuable insights "on an enigmatic period of natural global warming in Earth's relatively recent history." The results are published in the July 17 issue of Science.

The project was headed by Zhengyu Liu, a University of Wisconsin professor, and Bette Otto-Bliesner, a climate modeler from the National Center for Atmospheric Research. Their team simulated the natural global warming event, known as the Bolling-Allerod warming, that began taking place about 19,000 years ago. The climate-change researchers used two Cray supercomputing systems at ORNL, Jaguar and Phoenix, to do the simulations in 2008, and the work reportedly adds valuable data to the scientific understanding of causes and effects of global climate change,.
