Antarctic sea ice growth doesn't negate climate change, scientists say

LA Times: In the blue half-light of the Antarctic autumn, a thin film spreads across the continent's coastal waters. It's an embryonic form of sea ice: a mush of microscopic crystals that floats on the dense, salty water of the Southern Ocean. As winter takes root, this proto-sea ice grows thicker and stronger until it encircles Antarctica in a vast frozen ring. The ice spans nearly 7 million square miles at its peak, an area roughly twice the size of the United States. This year, Antarctic sea ice has expanded...
Study Finds Methane Leaks Negate Climate Benefits of Natural Gas

New York Times: The sign is ubiquitous on city buses around the country: "This bus runs on clean burning natural gas." But a surprising new report, to be published Friday in the journal Science, concludes that switching buses and trucks from traditional diesel fuel to natural gas could actually harm the planet's climate. Although burning natural gas as a transportation fuel produces 30 percent less planet-warming carbon dioxide emissions than burning diesel, the drilling and production of natural gas lead...

Methane leaks 'could negate climate benefits'

Guardian: Methane leaks could undo the climate change benefits of America's natural gas boom, a new report said on Tuesday. The report, produced by the Centre for Climate and Energy Solutions (C2ES), said America's shift from coal to gas had produced important climate gains. Carbon dioxide emissions fell last year to their lowest point since 1994, according to the Department of Energy. Energy-related carbon dioxide emissions were 12% below 2005 levels. But the report said those reductions were not...
