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 &...

Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot, a new study has found.Like a black car on a bright summer day, soot absorbs solar energy. Recent atmospheric models have ranked soot, also called black carbon, second only to carbon dioxide in potential for atmospheric warming. But particles, or aerosols, such as soot mix with other chemicals in the atmosphere, complicating estimates of their...

Researchers from the United States and around the world have determined springtime agricultural fires have a significant impact on the melting of arctic ice. The scientists are to meet at the University of New Hampshire next week to discuss findings from the most ambitious effort ever undertaken to measure short-lived airborne pollutants in the Arctic Circle. The two-year international project known as Polarcat focused on the transport of pollutants into the arctic from lower latitudes. Among...

Former Vice President Al Gore called for fast action to avert the potentially irreversible melting of the Earth's ice. Speaking at the first conference to exclusive discuss the planet's melting ice, the Nobel prize winning climate champion warned that the situation is worse than previous worst-case scenarios projected by experts just a few years ago. The Tromsoe, Norway, conference comes just months ahead of a U.N. climate summit set for December in Copenhagen. "This conference is a global...
