Greenhouse Gases into Gold

November 6, 2013 | Tags: Hopper, NERSC

Environmentalists have long lamented the destructive effects of greenhouse gases, with carbon dioxide (CO2) often accused of being the primary instigator of global climate change. As a result, numerous efforts are under way to find ways to prevent, capture and sequester—perhaps even bury—CO2 emissions and reduce their negative effects. But some researchers say CO2 is getting a bad rap. Read More »

Thriving Tundra Bushes Add Fuel to Northern Thaw

Carbon-gobbling plants are normally allies in the fight to slow climate change, but in the frozen north, the effects of thriving vegetation may actually push temperatures higher. In a series of climate simulations performed at NERSC, a group of researchers found that the spread of bushes, taller ones especially, could exacerbate warming in northern latitudes by anywhere from 0.6°C to 1.8°C per year. What’s more, taller species have the potential to warm tundra soil more deeply, threatening… Read More »
