Arctic Cruise Explores Changing Ocean Acidification

Scientists from the U.S. Geological Survey will embark on a research cruise to the Arctic Ocean beginning today to collect water samples and other data to determine trends in ocean acidification from the least explored ocean in the world.

Study: Late-’90s Arctic Ice Melt Caused Half by GHGs, Half by Normal Climate Conditions

These findings point to climate change and variability working together equally to accelerate the observed sea ice loss during the late 20th century.

Reversing E. Coli's Metabolism Produces Biofuels, Chemicals at Rapid Clip

Rice University engineering researchers unveiled a new method for rapidly converting simple glucose into biofuels and petrochemical substitutes

Ecologist: Young Forests Will Remain Important Carbon Sinks

The Ohio State researchers argue that in this case, as forests age, they get rejuvenated with younger individuals of different species – a more-complex and -diverse community will be replacing the old guard.

Americans of All Political Persuasions Pessimistic About Oil Prospects

While geologists and economists debate the specifics, American University School of Communication professor Matthew Nisbet believes peak petroleum and the associated risks to public health may provide an opportunity to bring conservatives and liberals together in the move toward alternative forms of energy.

White House Announces Fuel-Efficiency Standards for Heavy Duty Trucks, Buses

Under the comprehensive new national program, trucks and buses built in 2014 through 2018 will reduce oil consumption by a projected 530 million barrels and greenhouse gas (GHG) pollution by approximately 270 million metric tons.

Early Suntan Helps Lettuce Crops Bulk Up

New Zealand’s intense ultraviolet light may be bad for the skin, but it could provide a boost for vegetable production, according to new research by a Massey University crop scientist.

New NRDC Web Tool Analyzes Climate Change State by State

A new Web tool unveiled by NRDC lets users read how their state might be impacted by climate change.



Research Evaluates Emissions-Reduction Scenario

New computer modeling work shows that by 2100, if society wants to limit carbon dioxide in the atmosphere to less than 40 percent higher than it is today, the lowest cost option is to use every available means of reducing emissions.

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).

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.

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.

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.

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.

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.
