Layers of soot from coal burning melted Alpine glaciers even in cooler climate

Independent: Sooty air from coal burning triggered the initial melting of the mountain glaciers in the European Alps in the second half of the 19th Century when it caused the snow to turn grey and so reflect less sunlight back into space, scientists said. The soot, known as black carbon, caused the glaciers to absorb more heat than usual, causing the ice to recede year by year even though the regional temperatures were colder than today, the researchers found. Alpine glaciers have receded significantly over...

Scientists look for climate change clues in wildfire soot

KUOW: You may know that on a hot, sunny day its better to be sitting in a white car than a black one. White reflects sunlight, while black absorbs more of it. The same concept applies to researchers trying to figure out what effect wildfires have on climate change. And part of the answer is whether the smoke particles are dark or reflective. Outside of a white, paint-peeling hanger in Pasco, sits a glossy, small science plane. It looks like some kind of fancy jet airliner for executives. But onboard,...

No Clear Sign That Less Soot, Methane Reduces Global Warming
2013-08-14 16:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Reducing emissions of only soot and methane won`t do as much to reduce global warming as some previous research has suggested, according to a new study published Monday in the Proceedings of the National Academy of Sciences (PNAS). "Cutting back only on soot and methane emissions will help the climate, but not as much as previously thought," said study author Steve Smith, a climate researcher at the Department of Energy`s Pacific Northwest National Laboratory (PNL). The researchers advise focusing...

Curbing Methane and Soot Not as Helpful as Previously Thought, Study Suggests
2013-08-13 20:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Reducing the amount of short-lived, climate-warming emissions such as soot and methane may be as effective in limiting global warming as previously thought, a new analysis led by the Department of Energy's Pacific Northwest National Laboratory (PNNL) suggests. Soot, also known as black carbon, is largely given off by vehicles and wood stoves while methane, a component of natural gas, is released from a wide range of sources, including coal mines, oil wells, cattle, rice paddies and landfills....
