THE world faces an array of daunting environmental and energy challenges that are not going away any time soon.
Nuclear materials continue to pile up worldwide, posing national security and environmental threats.
Some nuclear materials already released to the environment are continuing to spread. Greenhouse gases accumulating in the atmosphere may threaten the environment and the world economy. The adequacy, security, and reliability of energy sources for personal and industrial needs are uncertain. These knotty issues are too large for any one institution or government to solve. But environmental scientists at Livermore are giving it their best shot, using their long-standing expertise in computer simulation to find new and better ways to address them.
