USGS Survey Says Fallen Leaves and Rain Both Add Same Amount of Mercury to the Environment

Fallen autumn leaves transfer as much, if not more, hazardous mercury from the atmosphere to the environment as does precipitation each year, according to recent U.S. Geological Survey research.

New Research Suggests Radioactive Decay is Key Ingredient Behind Earth's Heat

New research suggests that nearly half the Earth's heat comes from the radioactive decay of materials beneath the surface, according to a large international research collaboration that includes a Kansas State University physicist.

Some Replacements for CFC-Containing Refrigerants Much More Potent GHGs than CO2

While international climate talks remain deadlocked, the Montreal Protocol has been methodically eliminating some of the worst chemicals contributing to global warming.

Automakers Will Have to Meet 54.5 MPG Fuel Efficiency Standard By 2025

Building on the agreement for model year 2012-2016 vehicles, which will raise fuel efficiency to 35.5 mpg, the next round of standards will require performance equivalent to 54.5 mpg or 163 grams/ mile of CO2 for cars and light-duty trucks by model year 2025.

Caving for Climate

A group of scientists from the University of Alabama are exploring caves in the South Pacific to gain insight on ancient weather patterns.

Researchers: Energy Balance Is Key to Disparity Between Climate Models And Observed Temperatures

The previously unexplained differences between model-based forecasts of rapid global warming and meteorological data showing a slower rate of warming have been the source of often contentious debate and controversy for more than two decades.

Proposed Natural Gas Act Hits Washington

Senior energy executive Karl W. Miller is a major supporter in establishing a comprehensive energy plan for the U.S.

A Geological View of Global Erosion

Erosion happens. But for the modern geologist a vexing question remains: how fast does this erosion happen? For more than a century, scientists have looked for ways to measure and compare erosion rates across differing landscapes around the globe—but with limited success.



Arctic Tundra Fires Could Accelerate Climate Warming

After a 10,000-year absence, wildfires have returned to the Arctic tundra, and a University of Florida (UF) study shows that their impact could extend far beyond the areas blackened by flames.

Novel Gene Could Hold Key to Increasing Biofuel Production Efficiency

If researchers can coax yeast into processing more of the sugars found in biofuel feedstocks, they can improve the efficiency of producing renewable fuels from biomass crops like corn stover or switchgrass.

How 12 U.S. Cities are Dealing with Water-related Climate Change

As the nation grapples with a record year for storms, drought and weather-related devastation, a new report claims climate change is leaving American cities open to a range of water-related vulnerabilities –- from drought to sea level rise and increased rainfall –- regardless of region or size. The report looks at how communities facing these new extremes are trying to protect their water supplies and waterways.

Mexico City Reduces GHG Emissions by 5.7 Million Metric Tonnes

Greenhouse gas (GHG) emissions have been reduced by an accumulated 5.7 million metric tonnes (mt) in Mexico City since it began implementing its Green Plan in 2008, the Mexico City government recently announced.

Climate Change to Potentially Increase Yellowstone Wildfires

An increase in wildfires due to climate change could rapidly and profoundly alter the Greater Yellowstone Ecosystem, according to a new study authored by environmental engineering and geography Professor Anthony Westerling of the University of California, Merced.

Researchers Float Framework for Relocating Species Threatened by Climate Change

In a paper published in the journal Nature Climate Change, researchers from CSIRO, University of Queensland and United States Geological Survey present a pragmatic decision framework for determining when, if ever, to move species in the face of climate change.

Study: Increase in Aerosols Has Offset Some Recent Climate Warming

A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of carbon dioxide (CO2) change during the past decade, according to a new study led by NOAA and published today in the online edition of Science.

How Dairy Farms Contribute to Greenhouse Gas Emissions

U.S. Department of Agriculture scientists have produced the first detailed data on how large-scale dairy facilities contribute to the emission of greenhouse gases.

EPA to Protect Water Quality in Appalachian Communities from Mountaintop Mining

The U.S. Environmental Protection Agency (EPA) recently released final guidance on Appalachian surface coal mining, designed to ensure more consistent, effective, and timely review of surface coal mining permits under the Clean Water Act and other statutes.

Farms of the Future: Bio-Oil, Biochar from Biomass

Rural landscapes of the future might have pyrolysis plants instead of grain elevators on every horizon —processing centers where farmers would bring bulky crops such as switchgrass to be made into crude oil.

NASA's Aura Satellite Measures Pollution 'Butterfly' from Fires in Central Africa

Fires raging in central Africa are generating a high amount of pollution that is showing up in data from NASA's Aura Satellite, with the ominous shape of a dark red butterfly in the skies over southern part of the Democratic Republic of the Congo and northern Angola.

The Coast Guard's Arctic Agenda Heats Up

If regions were given hospitality rankings, the Arctic would fall somewhere between zero and below zero. Temperatures can plunge to −60 degrees Farenheit, and winds can exceed 75 mph. Half the year, skies are black, making icebergs dangerous obstacles.
