Complex, old-growth forests may protect some bird species in a warming climate

Fri, 15 Dec 2017 13:51:22 EST ~ Old forests that contain large trees and a diversity of tree sizes and species may offer refuge to some types of birds facing threats in a warming climate, scientists have found. Find out more...

How much soil goes down the drain: New data on soil lost due to water

Fri, 15 Dec 2017 12:10:55 EST ~ According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem. Find out more...

Exposure to larger air particles linked to increased risk of asthma in children

Fri, 15 Dec 2017 10:53:10 EST ~ Researchers report statistical evidence that children exposed to airborne coarse particulate matter a mix of dust, sand and non-exhaust tailpipe emissions, such as tire rubber are more likely to develop asthma and need emergency room or hospital treatment for it than unexposed children.

Northeast farmers weigh warming climate, drenched fields

Thu, 14 Dec 2017 15:33:44 EST ~ Farmers in the Northeast are adapting to longer growing seasons and warming climate conditions -- but they may face spring-planting whiplash as they confront fields increasingly saturated with rain, according to a research paper. Find out more...

Conserving the forests

Thu, 14 Dec 2017 15:33:39 EST ~ Certification programs are being reevaluated as options for sustaining tropical forests, explain scientists. Find out more...

NASA researchers share perspective on key elements of ozone layer recovery

Thu, 14 Dec 2017 14:44:36 EST ~ Each year, ozone-depleting compounds in the upper atmosphere destroy the protective ozone layer, and in particular above Antarctica. While different compounds each release either reactive chlorine or bromine, the two active ozone-destroying ingredients, during a series of chemical reactions, the molecules have a range of different lifetimes in the atmosphere that can affect their ultimate impact on the ozone layer and its future recovery.

Clearing the air

Thu, 14 Dec 2017 14:07:15 EST ~ A greater understanding of the dynamics of chemical reactions is leading to better models of atmospheric chemistry. Through this work, scientists are gaining insight into a key chemical able to break down some major air pollutants. Find out more...

Climate scientists study the odds of a U.S. megadrought

Thu, 14 Dec 2017 10:18:43 EST ~ To help untangle fact from speculation, scientists have developed a 'robust null hypothesis' to assess the odds of a megadrought -- one that lasts more than 30 years -- occurring in the western and southwestern United States. Find out more...

Increased air pollution linked to bad teenage behavior

Wed, 13 Dec 2017 14:37:20 EST ~ A new study linking higher levels of air pollution to increased teenage delinquency is a reminder of the importance of clean air and the need for more foliage in urban spaces. The study suggests ambient air pollution may increase delinquent behavior among 9- to 18-year-olds in urban neighborhoods in Greater Los Angeles. The insidious effects are compounded by poor parent-child relationships and parental mental and social distress, researchers report. Find out more...

World e-waste rises 8 percent by weight in 2 years as incomes rise, prices fall: UN-backed report

Wed, 13 Dec 2017 14:37:14 EST ~ The world's e-waste -- discarded products with a battery or plug -- reached a staggering 44.7 million metric tonnes in 2016 -- up 3.3 Mt or 8 percent from 2014. In 2016 world e-waste -- everything from end-of-life refrigerators and television sets to solar panels, mobile phones and computers -- equaled in weight almost nine Great Pyramids of Giza, or 1.23 million fully loaded 18-wheel 40-ton trucks, enough to form a line from New York to Bangkok and back.
