New clues as to how the Earth's remote ecosystems have been influenced by the Industrial Revolution are frozen in glaciers, according to a paper in the March issue of Nature Geoscience. "Remote regions are often perceived as being pristine and devoid of human influence," said Aron Stubbins, the study's lead author and an assistant professor at the Skidaway Institute of Oceanography. "Glaciers show us that burning fuels has an impact upon the natural functioning of ecosystems far removed...

The past decade has witnessed a significant growth in Asian air pollution, causing a great concern for air quality and climate. If government policy makers hope to contain the problem, they will need increased research and better computer models of black carbon and other aerosol pollutants, also known as atmospheric brown cloud (ABC), according to University of Iowa engineering professor Gregory Carmichael. Carmichael made the case for more research and better-informed policy makers when...

Fossil fuel signature found in Alaskan ice New clues as to how the Earth's remote ecosystems have been influenced by the industrial revolution are locked, frozen in the ice of glaciers. That is the finding of a group of scientists, including Robert Spencer of the Woods Hole Research Center. The research will be published in the March 2012 issue of Nature Geoscience. Globally, glacier ice loss is accelerating, driven in part by the deposition of carbon in the form of soot or "black...

Countries Join Forces To Reduce Short-Lived Climate Change Pollutants

U.S. Secretary of State Hillary Rodham Clinton and representatives from several other nations joined forces on Thursday to announce the formation of a new international coalition focused on reducing "short-lived" climate pollutant levels. According to John M. Broder of the New York Times, the nations are looking to curb emissions of soot (also known as black carbon), methane, and hydrofluorocarbons (which are used as refrigerants). Broder reports that these substances "contribute to...

New wall-to-wall carbon storage map can help developing nations track deforestation and report on emissions A study published in Nature Climate Change today finds that tropical vegetation contains 21 percent more carbon than previous studies had suggested. Using a combination of remote sensing and field data, scientists from Woods Hole Research Center (WHRC), Boston University, and the University of Maryland were able to produce the first "wall-to-wall" map (with a spatial resolution...

NASA Study Shows Health, Food Security Benefits From Climate Change Actions

A new study led by a NASA scientist highlights 14 key air pollution control measures that, if implemented, could slow the pace of global warming, improve health and boost agricultural production. The research, led by Drew Shindell of NASA's Goddard Institute for Space Studies (GISS) in New York City, finds that focusing on these measures could slow mean global warming 0.9 ºF (0.5ºC) by 2050, increase global crop yields by up to 135 million metric tons per season and prevent...

Shifting a fraction of truck-borne freight onto trains would have an outsized impact on air quality in the Midwest, according to researchers at the University of Wisconsin—Madison. Much of that impact boils down to simple efficiency, according to Erica Bickford, a graduate student in UW—Madison's Nelson Institute for Environmental Studies. For each ton they carry, long-distance trucks go about 150 miles on a gallon of diesel fuel. Trains can move a ton more than 400 miles per...

For many people in the developing world getting enough food to eat is a persistent challenge. However the challenge does not stop there. A new issue of the international journal Energy Policy details the human and environmental cost of cooking food using the only energy source available to many people, woody biomass.  The Special Issue explores the type of decision frameworks that are needed to guide policy development for clean cooking fuels and to ensure that the provision of clean...

A recent report provides new ideas regarding carbon and energy benefits forests and forest products provide. The report, Managing Forests Because Carbon Matters: Integrating Energy, Products, and Land Management Policy, summarizes and analyzes the most recent science regarding forests and carbon accounting, biomass use, and forest carbon offsets. A team of researchers from the U.S. Forest Service, several universities, and natural resource and environmental organizations coauthored the...
