Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities. Temperatures on the Tibetan Plateau -- sometimes called Earth's "third pole" -- have warmed by 0.3°C (0.5°F) per decade over the past 30 years, about...

GREENBELT, Md., Dec. 14 /PRNewswire-USNewswire/ -- A NASA-led study has found new evidence that a "heat pump" effect, driven by emissions of soot, or black carbon, contributes as much (or more) to atmospheric warming in the Himalayas as greenhouse gases. This warming fuels the melting of glaciers and could threaten fresh water resources in a region that is home to more than a billion people.

Soot, ozone and methane need attention to deal with near term impacts on climate When world leaders meet in Copenhagen in December to hash out a treaty limiting carbon dioxide emissions, they should begin planning a future summit to address other pollutants "“ from soot to ozone "“ that don't remain in the atmosphere as long as carbon dioxide, but nevertheless are major contributors to global warming. That is the view of University of California, Berkeley, researcher Stacy C....

WASHINGTON, Oct. 12 /PRNewswire-USNewswire/ -- Reducing non-CO2 climate change agents such as black carbon soot, tropospheric ozone, and hydrofluorocarbons (HFCs), as well as expanding bio-sequestration through biochar production, can forestall fast approaching abrupt climate changes, according to Nobel Laureate Dr. Mario Molina and co-authors in a paper published today in the Proceedings of the National Academy of Sciences (PNAS).

SAN FRANCISCO, Oct. 1 /PRNewswire/ -- The South Australian state of Victoria has become the first in the world to effectively inventory the amount of carbon stored in its public forests, parks and reserves using a carbon accounting system proposed by the Australian government's cap-and-trade system. "This new information will help Victorian landowners to enter the carbon market, identify reforestation sites and measure carbon on their own land," said Victoria Environment and Climate...

The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study.Led by Max Zhang, assistant professor of mechanical and aerospace engineering, the study indicates that such measures as regulating traffic density and encouraging public transportation can have a significant impact on local air...

Smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012, U.S. researchers said. James Winebrake of the Rochester Institute of Technology and colleagues note that the current finding is almost one-third higher than previously believed. Winebrake said most oceangoing ships burn fuels with a high sulfur content. The smokestacks emit sulfur-containing particles linked to increased risk of lung and heart disease. A 2007 study by the researchers...

Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 "” almost one-third higher than previously believed, according to the second major study on that topic. The study says that government action to reduce sulfur emissions from shipping fuel (the source of air pollution linked to an increased risk of illness and death) could reduce that toll. The study is in the current issue of ACS' Environmental Science &...
