Study Suggests Switching from Coal to Natural Gas Would do Little for Global Climate

Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears this week in the Springer journal Climatic Change Letters.

Exceptional Drought Hits Record Levels in Three More U.S. States

The percent of land area experiencing exceptional drought reached record levels in August in three U.S. states – Texas, Oklahoma and Kansas – amid new concerns about how long the conditions may persist, an official with the National Drought Mitigation Center at the University of Nebraska-Lincoln said.

Pennsylvania DCNR Warns Heavy, Rain Flooding Boost Risk of Landslides

Recent heavy rain and flooding has increased the danger of landslides on moderate to steep slopes, according to scientists in the Bureau of Topographic and Geologic Survey in the Department of Conservation and Natural Resources (DCNR).

First Global Portrait of Greenhouse Gases Emerges from Pole-to-Pole Flights

The far-reaching field project, known as HIPPO, is enabling researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth’s climate.

Texas A&M Study Shows Clouds Don't Cause Climate Change

Clouds only amplify climate change, says a Texas A&M University professor in a study that rebuts recent claims that clouds are actually the root cause of climate change.

Crop Performance Matters When Evaluating Greenhouse Gas Emissions

Measuring the emission of greenhouse gases from croplands should take into account the crops themselves, according to new research.

Were the East Coast Hurricane and Earthquake Related?

An earthquake and a hurricane, all in the same week, on the same coast. Are they related?

Climate Change Seems Unfavorable for Toxic Blue Algae

The earth is warming up due to rising carbon dioxide concentrations in the atmosphere. NWO-funded researchers have discovered that the increase in carbon dioxide can reduce the nuisance caused by toxic blue algae, a bacterium commonly found in swimming water throughout the Netherlands in the summer



Feeding Cows Natural Plant Extracts Can Reduce Ammonia Emissions, Feeding Costs

With citizens’ groups seeking government regulation of foul-smelling ammonia emissions from large dairy farms, scientists reported that adding natural plant extracts to cow feed can reduce levels of the gas by one-third while reducing the need to fortify cow feed with expensive protein supplements.

Even Low Doses of Pesticides Can Put Honeybees at Risk

Scientists in France have discovered that honeybees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides

Up From the Depths: How Bacteria Capture Carbon in the Twilight Zone

Details are now emerging about a microbial metabolic pathway that helps solve the mystery of how certain bacteria capture carbon in the dark ocean, enabling a better understanding of what happens to the carbon that is fixed in the oceans every year.

Scientist Puts Forth a 'Fast, Cheap' Way to Slow Global Warming

A new study of dust-like particles of soot in the air provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported.

Wastewater Recycling Can Multiply Greenhouse Gas Emissions

New research shows that wastewater recycling processes may generate more greenhouse gases than traditional water-treatment processes. Despite this finding, there are good reasons to continue keep wastewater recycling among the water-resource tools for urban areas

Scientist Floats New Hypothesis on Ocean Acidification

A researcher at the Hawai'i Institute of Marine Biology, an organized research unit in the University of Hawai'i at Manoa's School of Ocean and Earth Science and Technology has come up with a new explanation for the effects of ocean acidification on coral reefs.

Greenhouse Effect Could Extend Habitable Zone

The distant region beyond Saturn is too cold for liquid water, a necessity for life as we know it. New research indicates that rocky planets far from their parent star could generate enough heat to keep water flowing - if their atmospheres were made up primarily of hydrogen.

Scientists Call for Better Deep Sea Management

A recent study has found that it's being damaged by human activities, and that this is only likely to get worse. Scientists are now calling for better management and conservation of entire deep-sea ecosystems.

As Droughts Decrease Water for Irrigation, Less-Productive Crops Consume Less Carbon

Water shortages - already forecasted to be a big problem as the world warms - could contribute to yet more warming through a positive feedback loop.

Irrigation Impacts on Global Carbon Uptake

Globally, irrigation increases agricultural productivity by an amount roughly equivalent to the entire agricultural output of the U.S., according to a new University of Wisconsin-Madison study.

Study Casts Doubt on Drought-Driven Declines in Plant Productivity, Global Food Security

A new study published in the current issue of Science rebuts earlier claims that drought has induced a decline in global plant productivity during the past decade and poses a threat to global food security.

Study Shows Climate Cycles May Be Driving Wars

The arrival of El Niño, which every three to seven years boosts temperatures and cuts rainfall, doubles the risk of civil wars across 90 affected tropical countries, and may help account for a fifth of worldwide conflicts during the past half-century, say the authors.
