Anthropogenic Nitrogen Plays a Double Role in Climate Change

According to a new paper by researchers around the team of Sönke Zaehl from the Max Planck Institute for Biogeochemistry, nitrogen's detrimental effects on the climate roughly correspond to its climactic benefits. In fact, the scientists' findings suggest that the negative impacts of nitrogen may even slighty prevail.

Food Transportation Moves Carbon from Farms to Markets

New research published in the journal Biogeosciences provides a detailed account of how carbon naturally flows into and out of crops themselves as they grow, are harvested and are then eaten far from where they're grown. The paper shows how regions that depend on others to grow their food end up releasing the carbon that comes with those crops into the atmosphere.

CO2-Caused Ocean Acidification Will Reduce Mollusk Harvests

Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more intensely than others, according to a study by scientists at Woods Hole Oceanographic Institution (WHOI, USA).

High Mold Air Alert Issued For Midwest

Residents in the Midwest awoke to the highest mold count for the season after a night of torrential rain and lightening strikes. An official air alert was issued by Joseph Leija, MD, allergist who performs the official allergy count for the Midwest for the National Allergy Bureau.

IEA Examines Whether Carbon Pricing Makes Energy-Efficiency Policies Redundant

To date, many academics and government officials have argued that putting a price on carbon – most commonly through taxes or emissions trading – is all that is needed to overcome every possible barrier to delivering cost-effective energy efficiency improvements.

Tiny, Symbiotic Fungi May Hold the Key to Adapting Plants to Climate Change

Rice – which provides nearly half the daily calories for the world’s population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, U.S. Geological Survey-led research shows.

Calcifying Microalgae Are Witnesses of Increasing Ocean Acidification

Coccolithophores, a certain group of algae, form thinner calcite skeletons when the pH value in the ocean drops. In marine ecosystems, changes in the degree of calcification are much more pronounced than presumed to date based on laboratory tests. These changes have an impact on the global carbon balance since the examined microalgae influence the carbon dioxide exchange between ocean and atmosphere.

Slowing Climate Change by Targeting Gases Other Than Carbon Dioxide

Carbon dioxide still plays a major role in climate change, but other greenhouse gases contribute to the problem.



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.

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.

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.

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.
