Black Carbon More Powerful Contributor to Climate Change Than Previously Thought: New Study
2013-01-17 21:34:00| Climate Ark Climate Change & Global Warming Newsfeed
Huffington Post: Black carbon -- that nasty air pollution that causes major health problems -- also happens to be a very powerful contributor to climate change. In fact, a new multi-year international study has just found that it's the second most powerful contributor to climate change -- behind carbon dioxide emissions. Emissions from dirty diesel, residential cooking and heating and forest fires from deforestation are major contributors to black carbon pollution (see figure). Addressing black carbon emissions from...

Black carbon is worse for global warming than previously thought

Yale Environment 360: It rises from the chimneys of mansions and from simple hut stoves. It rises from forest fires and the tail pipes of diesel-fueled trucks rolling down the highway, and from brick kilns and ocean liners and gas flares. Every day, from every occupied continent, a curtain of soot rises into the sky. What soot does once it reaches the atmosphere has long been a hard question to answer. It's not that scientists don't know anything about the physics and chemistry of atmospheric soot. Just the opposite:...

Burning Fuel Particles Do More Damage to Climate Than Thought, Study Says
2013-01-16 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: The tiny black particles released into the atmosphere by burning fuels are far more powerful agents of global warming than had previously been estimated, some of the worlds most prominent atmospheric scientists reported in a study issued on Tuesday. These particles, which are known as black carbon and are the major component of soot, are the second most important contributor to global warming, behind only carbon dioxide, wrote the 31 authors of the study, published online by The Journal of Geophysical...

Black carbon causes twice as much global warming than previously thought
2013-01-15 18:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Soot from burned wood and diesel exhausts may have twice the impact on global warming than previously thought, according to a new study published on Tuesday. The "black carbon" is said to be the second most important man-made agent of climate change. The findings, published in the Journal of Geophysical Research Atmospheres, suggest there may be untapped potential to curb global warming by reducing soot emissions. Huge quantities of man-made soot enter the atmosphere every year. Around 7.5m...

Biofuels cause pollution, not as green as thought - study
2013-01-07 03:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Green schemes to fight climate change by producing more bio-fuels could actually worsen a little-known type of air pollution and cause almost 1,400 premature deaths a year in Europe by 2020, a study showed on Sunday. The report said trees grown to produce wood fuel - seen as a cleaner alternative to oil and coal - released a chemical into the air that, when mixed with other pollutants, could also reduce farmers' crop yields. "Growing biofuels is thought to be a good thing because it reduces...
