For decades, no one worried much about the air quality inside people’s homes unless there was secondhand smoke or radon present. Then scientists at Lawrence Berkeley National Laboratory made the discovery that the aggregate health consequences of poor indoor air quality are as significant as those from all traffic accidents or infectious diseases in the United States. They are now working on turning those research findings into science-based solutions, including better standards for residential buildings and easier ways to test for the hazardous pollutants.
If you think it’s been unusually hot lately, just wait—by the end of the century, temperatures in California are expected to rise significantly. Looking at a range of future climate scenarios, Larry Dale, an economist at Berkeley Lab, found that California may need as much as 30 to 40 percent more generation and transmission capacity per capita by the end of the century because of the negative effect of higher temperatures on equipment performance.
More Potent than Carbon Dioxide, Nitrous Oxide Levels in California May be Nearly Three Times Higher Than Previously Thought
Using a new method for estimating greenhouse gases that combines atmospheric measurements with model predictions, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found that the level of nitrous oxide, a potent greenhouse gas, in California may be 2.5 to 3 times greater than the current inventory. At that level, total N2O emissions—which are believed to come primarily from nitrogen fertilizers used in agricultural production—would account for about 8 percent of California’s total greenhouse gas emissions.
A multi-institutional team led by scientists at Berkeley Lab have directly observed electron hopping in iron oxide particles, a phenomonon that holds huge significance for a broad range of environment- and energy-related applications.
New research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found that levels of methane—a potent greenhouse gas emitted from many man-made sources, such as coal mines, landfills and livestock ranches—are at least one-and-a-half times higher in California than previously estimated.
