NOAA, USGS, partners predict an average 'dead zone' for Gulf of Mexico

Scientists forecast that this year's Gulf of Mexico dead zone--an area of low to no oxygen that can kill fish and marine life - will be approximately 5,898 square miles or about the size of Connecticut, the same range as it has averaged over the last several years.

Low ice, low snow, both poles

Daily Arctic sea ice extents for May 2016 tracked two to four weeks ahead of levels seen in 2012, which had the lowest September extent in the satellite record. Current sea ice extent numbers are tentative due to the preliminary nature of the DMSP F-18 satellite data, but are supported by other data sources. An unusually early retreat of sea ice in the Beaufort Sea and pulses of warm air entering the Arctic from eastern Siberia and northernmost Europe are in part driving below-average ice conditions. Snow cover in the Northern Hemisphere was the lowest in fifty years for April and the fourth lowest for May. Antarctic sea ice extent grew slowly during the austral autumn and was below average for most of May.

Is sunscreen bad for coral reefs?

You only use a little bit of sunscreen — a squeeze of the bottle or two or three sprays. Sure, it has some chemical ingredients, but it won’t kill anyone, right? Wrong. Sunscreen is actually one of the culprits of putting over 60 percent of the planet’s coral reefs in critical danger — and bringing a whole lot of other wildlife down with them.

Environmental and health impacts of US health-care system

If the U.S. healthcare system were a country, it would rank 13th in the world for greenhouse gas emissions, according to new research. The study, published June 9 in PLOS ONE, quantified previously unreported environmental and public health impacts of the nation's healthcare sector.

Climate change mitigation: Turning CO2 into rock

An international team of scientists have found a potentially viable way to remove anthropogenic (caused or influenced by humans) carbon dioxide emissions from the atmosphere - turn it into rock.The study, published today in Science, has shown for the first time that the greenhouse gas carbon dioxide (CO2) can be permanently and rapidly locked away from the atmosphere, by injecting it into volcanic bedrock. The CO2 reacts with the surrounding rock, forming environmentally benign minerals.

The role of dam removal in river management in New England

Dam removal in New England is not only an important aspect of river restoration but it also provides an opportunity to enhance the magnitude and rate of river re-connection, and improve watershed resilience in response to human impact on the environment, if a broader strategic removal approach is implemented throughout the region, according to a new Dartmouth-led study published in Elementa: Science of the Anthropocene.The study is the first interdisciplinary, region-wide assessment of the social and biophysical impacts of dam removal and was conducted by researchers at Dartmouth, American Rivers and the USDA Forest Service. 

Using Lake Michigan turtles to measure wetland pollution

Decades of unregulated industrial waste dumping in areas of the Great Lakes have created a host of environmental and wildlife problems. Now it appears that Lake Michigan painted and snapping turtles could be a useful source for measuring the resulting pollution.

Greenland's 2015 melt records consistent with 'Arctic amplification'

Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Arctic amplification.

Renewable Energy Hit Record Levels in 2015

A new report confirms that 2015 was a record-breaking year for renewable energy in which 147 Gigawatts of renewable electricity came online.That figure represents the largest annual increase ever recorded, and is due in part to the $286 billion invested in renewables. In fact, in 2015 almost twice as much money was spent on renewable energy, like solar and wind power, than fossil fuels like gas-fired power stations — only $130 billion.This information comes as part of the Renewables Global Status Report authored by the global renewable energy policy network known as REN21.  

Tropical Depression 1E dissipates

Tropical Depression 1E or TD1E didn't get far from the time it was born to the time it weakened to a remnant low pressure area along the southwestern coast of Mexico. NOAA's GOES-West satellite captured an image of it remnant clouds.
