Latest Global dimming Stories
Thick smog clouds that loom over Asia threaten the livelihood of crops and contain particles that actually reflect the sunâ€™s rays away from the earth, the UN reported on Thursday.
BELTSVILLE, Md. _ NASA plans to launch a new satellite next year that will help scientists fill in a gap in their understanding of global warming: the role of clouds and airborne particles.
Using sophisticated unmanned aircraft, research scientists at Scripps Institution of Oceanography, UC San Diego hope to assess Southern California's potential for climate change and better understand the sources of air pollution.
Black carbon, the stuff that gives soot its dirty color, could be the second most important contributor to climate change after carbon dioxide and a key to preventing warming, at least in the short-run, a new study suggests. Black carbon is a type of aerosol - a small particle suspended in the atmosphere - that is produced in diesel exhaust and when wood, coal or other types of solid fuel are burned. Like other aerosols, soot particles absorb and scatter the sun's radiation; black...
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists.
Scientists at the University of Liverpool have found that natural variability in the earthâ€™s atmosphere could be masking the overall effect of global warming in the North Atlantic Ocean.
A new NASA study estimates that most ground-level particulate pollution in the United States stems from regional sources in North America and only a small amount is brought to the country from other parts of the world.
Scientists using the nation's newest and most capable aircraft for environmental research are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America.
Less sunlight reaching the Earth's surface has not translated into cooler temperatures, according to a team of solar physicists at New Jersey Institute of Technology (NJIT).
Summers are getting sunnier in Oregon, according to evidence presented today by University of Oregon physicists during the 2005 Solar World Congress in Orlando. The study is a first step toward testing and refining regional climate models for the Pacific Northwest that will help track global warming.
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
