Diseases caused by pollution were responsible in 2015 for an estimated 9 million premature deaths -- 16 percent of all deaths worldwide, according to a report.
Life goes on for marine ecosystems after cataclysmic mass extinction
Fri, 20 Oct 2017 09:22:26 EDT
One of the largest global mass extinctions did not fundamentally change marine ecosystems, scientists have found.
Danger to Air Quality from Forest Fires
Thu, 19 Oct 2017 10:08:05 EDT
A report on forest fires confirms a trend towards longer and more intense fire seasons in Europe and neighboring regions, with wildfires now occurring throughout the year. The report coincides with an international study which finds that global wildfire trends could have significant health implications due to rising harmful emissions.
Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report
Wed, 18 Oct 2017 12:17:06 EDT
Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.
Study shows how water could have flowed on 'cold and icy' ancient Mars
Tue, 17 Oct 2017 11:43:41 EDT
Research by planetary scientists finds that periodic melting of ice sheets on a cold early Mars would have created enough water to carve the ancient valleys and lakebeds seen on the planet today.
A new way to harness wasted methane
Tue, 17 Oct 2017 11:43:28 EDT
Scientists have identified a process that could be used to harness methane that is now wasted by being burned off at wellheads.
Rivers carry plastic debris into the sea
Tue, 17 Oct 2017 11:00:28 EDT
Every year, millions of tons of plastic debris ends up in the sea. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers.
Link between forest fire smoke and pollution events discovered
Mon, 16 Oct 2017 14:48:48 EDT
Smoke from forest fires might contribute to more than half of certain gritty air pollution events in the continental U.S. during the summer, and as much as 20 percent of those events throughout the year, according to new research.
Cocktail tests on toxic waste called for
Mon, 16 Oct 2017 09:27:15 EDT
Surprisingly low concentrations of toxic chemicals -- from fungicides to antidepressants -- can change the way some aquatic creatures swim and feed, according to new research. In addition, depending on the cocktail of toxins they can produce unexpected results.
Combination of El Niño and 2016 Ecuador earthquake likely worsened Zika outbreak
Thu, 12 Oct 2017 20:02:02 EDT
A Zika virus outbreak in coastal Ecuador in 2016 was likely worsened by a strong El Niño and a magnitude 7.8 earthquake that struck the region in April, according to a new study.
Even modest oil exposure can harm coastal and marine birds
Thu, 12 Oct 2017 15:18:09 EDT
Many birds and other wildlife die following an oil spill, but there are also other potential long-terms effects of oil exposure on animals.
Carbon dioxide levels lower than thought during super greenhouse period
Thu, 12 Oct 2017 10:37:37 EDT
Researchers adds to the understanding of Earth's historic hyperthermal events to help explain the planet's current warming trend.
New threat to the ozone layer
Thu, 12 Oct 2017 09:10:09 EDT
'Ozone depletion is a well-known phenomenon and, thanks to the success of the Montreal Protocol, is widely perceived as a problem solved,' say some. But an international team of researchers, has now found an unexpected, growing danger to the ozone layer from substances not regulated by the treaty.
Bio-methane transforms from landfill waste to energy source
Wed, 11 Oct 2017 18:00:48 EDT
Most manure just sits around. Anaerobic digesters take those piles and place them in large covered tanks and convert waste into an energy source. Chemical engineers examined the carbon footprint of anaerobic digestion.
Doubt cast on warming implications of brown carbon aerosol from wildfires
Wed, 11 Oct 2017 15:13:50 EDT
As devastating wildfires rage in California wine country, a team of environmental engineers have made a new discovery about wildfire smoke, and its effect on the atmosphere.
