Cutting Methane, Soot Not Enough to Tackle Warming

2014-11-04 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: If the race to warm the planet were a children's allegory, carbon dioxide would be considered the tortoise, while soot and methane would play the role of the hare. In reality, as in fairy tales, the tortoise is going to win. Recent focus on targeting methane, soot and other short-term pollutants to combat climate change is not going to keep global warming in check if CO2 is not also slashed to stop its long-term impact, a new study says. The research, published this week in the Proceedings...

Methane emissions may swell from behind dams

2014-10-30 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: Imagine nearly 6,000 dairy cows doing what cows do, belching and being flatulent for a full year. That's how much methane was emitted from one Ohio reservoir in 2012. Reservoirs and hydropower are often thought of as climate friendly because they don't burn fossil fuels to produce electricity. But what if reservoirs that store water and produce electricity were among some of the world's largest contributors of greenhouse gas emissions? Harsha Lake, a large reservoir near Cincinnati, Ohio, emitted...

Space-based methane maps find largest U.S. signal in Southwest

2014-10-11 18:32:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: An unexpectedly high amount of the climate-changing gas methane, the main component of natural gas, is escaping from the Four Corners region in the U.S. Southwest, according to a new study by the University of Michigan and NASA. The researchers mapped satellite data to uncover the nation's largest methane signal seen from space. They measured levels of the gas emitted from all sources, and found more than half a teragram per year coming from the area where Arizona, New Mexico, Colorado and Utah...

How scientists overlooked 2,500-square-mile cloud of methane over Southwest

2014-10-11 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Christian Science Monitor: Scientists have identified the largest hotspot of methane gas in the United States hovering over the Four Corners region of the Southwest, and the find could have big implications for how the country tracks its emissions in the future. Scientists first noticed the data years ago amid satellite measurements collected by the European Space Agency's Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) instrument. The SCIAMACHY instrument collected atmospheric data over...
