NASA Graphic Shows Severity of Rainstorm That Caused Louisiana Flooding
August 17, 2016 03:34 PM - Yale Environment 360

A new graphic created by NASA and the Japan Aerospace Exploration Agency illustrates the severity of a recent rainstorm that caused widespread flooding in Louisiana this week, killing 11 people and forcing tens of thousands of residents from their homes. 

Flowering meadows benefit humankind
August 17, 2016 03:16 PM - Technical University of Munich (TUM) via EurekAlert!

The more it swarms, crawls and flies the better it is for humans. This is the finding of a study published in "Nature". More than 60 researchers from a number of universities were involved, including the Technical University of Munich, the Institute of Plant Sciences at the University of Bern and the Senckenberg Biodiversity and Climate Research Centre in Frankfurt. A diverse ecosystem populated by many species from all levels of the food chain provides higher levels of ecosystem services, the team reports. Even rather unpopular insects and invisible soil-dwelling organisms are important in maintaining a wide range of ecosystem services. The results underline the necessity of maintaining species-rich ecosystems for the good of humanity.

Sea ice strongly linked to climate change in past 90,000 years

"The Arctic sea ice responded very rapidly to past climate changes. During the coldest periods of the past 90,000 years the sea ice edge spread relatively quickly to the Greenland-Scotland Ridge, and probably far into the Atlantic Ocean." says first author Ulrike Hoff, a researcher at Centre for Arctic Gas Hydrate, Environment and Climate (CAGE).

Sea ice amplifies the climate changes that are occurring at any given time. Its growth and melting has profound effects on climate, the marine environment and ocean circulation.

Slower snowmelt affects downstream water availability in western mountains
August 17, 2016 09:32 AM - UNIVERSITY OF NEVADA, RENO via EurekAlert!

Western communities are facing effects of a warming climate with slower and earlier snowmelt reducing streamflows and possibly the amount of water reaching reservoirs used for drinking water and agriculture, according to a study published in July.

"As the climate warms, there is actually a slower snowmelt - both in timing and rates, which makes for a less efficient streamflow," Adrian Harpold, ecohydrologist at the University of Nevada, Reno said. Harpold, who initiated the study two years ago at the University of Colorado Boulder, is a co-author of the paper published in AGU publications Geophysical Research Letters.

Solid batteries improve safety
August 16, 2016 05:03 PM - ETH ZURICH via EurekAlert!

Lithium-ion batteries store a lot of energy in a small space, making them the energy source of choice for mobile electronic devices. Today, mobile phones, laptops, e-bikes and electric cars are all powered by such batteries. Researchers at ETH Zurich have now developed a type of battery that, unlike conventional ones, consists entirely of solid chemical compounds and is non-flammable.

Conventional lithium-ion batteries are not without their dangers: mobile phone batteries have exploded several times in the past, resulting in injuries, and only six months ago an entire row of houses burned down in the old town of Steckborn on Lake Constance. The blaze was caused by a model-making battery that allegedly caught fire due to being charged improperly.

Offshore Wind Moves a Step Closer for North Carolina
August 16, 2016 03:39 PM - Sami Grover, Care2

While we’re a long way behind countries like the UK, there seems to be a growing momentum behind US offshore wind development—suggesting we might finally get serious about the incredible potential for this increasingly competitive technology. The latest such signal is an announcement from the Department of Interior proposing a lease sale for the 122,405-Acre Kitty Hawk Wind Energy Area.

Overfishing on Coral Reefs Reduces Nutrients Healthy Ecosystems Need
August 16, 2016 03:16 PM - Center for Biological Diversity

Overfishing of large and top predatory fishes on Caribbean coral reefs substantially reduces the amount of nutrients stored and recycled within the ecosystem by fishes, new interdisciplinary research published today in Nature Communications concludes.

The study, by scientists at the University of Washington, the Center for Biological Diversity, the Smithsonian Institution and North Carolina State University, suggests that while avoiding local extinction of fish species is a conservation priority, management actions that preserve large fish groups such as sharks, groupers, snappers and jacks are needed to maintain an adequate flow of nutrients within ecosystems.

Mapping the health threat of wildfires under climate change in US West
August 16, 2016 03:08 PM - Yale School of Forestry & Environmental Studies via ScienceDaily

A surge in major wildfire events in the U.S. West as a consequence of climate change will expose tens of millions of Americans to high levels of air pollution in the coming decades, according to a new Yale-led study conducted with collaborators from Harvard.

The researchers estimated air pollution from past and projected future wildfires in 561 western counties, and found that by mid-century more than 82 million people will experience "smoke waves," or consecutive days with high air pollution related to fires.

The regions likely to receive the highest exposure to wildfire smoke in the future include northern California, western Oregon, and the Great Plains.

Today's electric vehicles can make a dent in climate change
August 16, 2016 02:51 PM - Massachusetts Institute of Technology via ScienceDaily

Electric cars that exist today could be widely adopted despite range constraints, replacing about 90 percent of existing cars, and could make a major dent in the nation's carbon emissions, new research indicates.

The study, which found that a wholesale replacement of conventional vehicles with electric ones is possible today and could play a significant role in meeting climate change mitigation goals, was published today in the journal Nature Energy by Jessika Trancik, the Atlantic Richfield Career Development Associate Professor in Energy Studies at MIT's Institute for Data, Systems, and Society (IDSS), along with graduate student Zachary Needell, postdoc James McNerney, and recent graduate Michael Chang SM '15.

Methane leaks: A new way to find and fix in real time
August 16, 2016 10:07 AM - University of Michigan via ScienceDaily

Researchers have flown aircraft over an oil and gas field and pinpointed -- with unprecedented precision -- sources of the greenhouse gas methane in real time. The technique led to the detection and immediate repair of two leaks in natural gas pipelines in the Four Corners region of the U.S. Southwest.

The technique led to the detection and immediate repair of two leaks in natural gas pipelines in the Four Corners region of the U.S. Southwest. The approach could inform strategies for meeting new federal limits on methane emissions from the oil and gas industry. Methane emissions have spiked in recent decades along with the boom in natural gas drilling.
