| Director Jim Hack Testifies on Climate Modeling |
| Oak Ridge LCF director Jim Hack recently testified before the U.S. Senate on the intricacies of climate modeling. Hack spoke at the hearing on "Improving the Capacity of U.S. Climate Modeling for Decision-Makers and Other End-Users" on May 8, before the committee on Commerce, Science, and Transportation. One of the world's foremost experts on computational climate modeling, Hack stressed future investments in computational algorithms to improve the accuracy of future-predicting climate models and a "close and continuing collaboration among the climate, facilities, applied mathematics, and computer science communities." |
Hack is in charge of a new program at Oak Ridge to coordinate the various climate-related research activities taking place at the lab in different organizations. "There is no single pacing item to the advancement of climate change science, but a collection of interrelated science and technology challenges," he said. "Many of the issues discussed in this testimony speak to the need for a balanced investment portfolio in computational infrastructure, climate science, computer science, and applied mathematics. In the short and long term, computational capability remains a significant bottleneck and should remain a high-priority investment."
