SCIENTIFIC DISCOVERYNew Climate Report Shows Regional ImpactsEvan Mills and Michael Wehner, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, contributed to the analysis of the effects of climate change on all regions of the United States, described in a major report released June 16, 2009 by the multi-agency U.S. Global Change Research Program. For the southwest region of the United States the report forecasts a hotter, drier climate with significant effects on the environment, agriculture and health. Global Climate Change Impacts in the United States covers such effects as changes in rainfall patterns, drought, wildfire, Atlantic hurricanes, and effects on food production, fish stocks and other wildlife, energy, agriculture, water supplies, and coastal communities. The report addresses nine zones of the United States (Southwest, Northwest, Great Plains, Midwest, Southeast, Northeast, Alaska, U.S. islands, and coasts), and describes potential climate change effects in each. Some states may fall in more than one zone; California is part of the southwest zone, but also the coastal zone. The precipitation map shown is one of the projections developed by Wehner. It shows, among other things, a substantial reduction in springtime rains in California, and summertime rains in the Pacific Northwest. “Even in areas where precipitation is projected to increase, higher temperatures will cause greater evaporation leading to a future where drought conditions are the normal state. In the southwest United States, water resource issues will become a major issue,” says Wehner. more

Witold Nazarewicz received an honorary doctorate from University of the West of Scotland at its gradation ceremony on July 8 in Paisley, Scotland. Witek, who is joint faculty with the University of Tennessee and scientific director of the Holifield Radioactive Ion Beam Facility, was also recently appointed a visiting professor at UWS following a three-month Carnegie Centenary Professorship that he held last year. Witek is co-PI of the SciDAC UNEDF project.
Researcher Cecilia Aragon was among the 100 researchers named last week by President Barack Obama to receive the prestigious Presidential Early Career for Scientists and Engineers (PECASE) Award, the highest honor bestowed by the United States government on early-career researchers. Together with two other young scientists from LBNL, Cecilia will receive her award in the fall at a White House ceremony.
The award recognized Aragon's groundbreaking research in data-intensive scientific workflow management, and pioneering development of innovative methods for visualization, analysis, and organization of massive scientific data sets, which will be critical to the success of the Department of Energy (DOE) mission.
Speeding up Data Transfers: Bigger Pipes between NERSC and NCCSNetwork systems engineers from the Department of Energy’s (DOE) Energy Sciences Network (ESnet), National Energy Research Scientific Computing Center (NERSC) and National Center for Computational Science (NCCS) are teaming up to optimize wide-area network (WAN) data transfers. NCCS, located at Oak Ridge National Laboratory in Tennessee and host to the Oak Ridge Leadership Computing Facility (OLCF), and NERSC, located at Lawrence Berkeley National Laboratory in California, are home to some of the fastest supercomputers in the world. A number of research groups use resources at both centers. ESnet, DOE’s high-speed network, connects the two centers, as well as other national labs and universities around the country. With the installation and deployment of new dedicated data transfer nodes at NERSC and NCCS linked by ESnet, researchers are now able to move large data sets between each facility’s mass storage systems at a rate of 200 megabytes per second (MB/sec). At this rate, 74 terabytes of information in the U.S. Library of Congress’ digital collection could be transferred in approximately four days. more |
