Land-based bird populations are at risk of local extinction

Thu, 20 Sep 2018 20:32:41 EDT ~ A new report finds that land-based bird populations are becoming confined to nature reserves in some parts of the world -- raising the risk of global extinction -- due to the loss of suitable habitat. Find out more...

Commitment to democratic values predict climate change concern, study finds

Thu, 20 Sep 2018 16:10:57 EDT ~ In a new study comparing climate change attitudes across 36 countries, including the United States, commitment to democratic values is the strongest predictor of climate change concern globally. Find out more...

Glacial engineering could limit sea-level rise, if we get our emissions under control

Thu, 20 Sep 2018 10:21:38 EDT ~ Targeted engineering projects to hold off glacier melting could slow down ice-sheet collapse and limit sea-level rise, according to a new study. While an intervention similar in size to existing large civil engineering projects could only have a 30 percent chance of success, a larger project would have better odds of holding off ice-sheet collapse. But the researchers caution that reducing emissions still remains key to stopping climate change and its dramatic effects. Find out more...

Flood frequency of Amazon River has increased fivefold

Thu, 20 Sep 2018 07:58:57 EDT ~ A recent study of more than 100 years of river level records from the Amazon shows a significant increase in frequency and severity of floods. Find out more...

From crystals to climate: 'Gold standard' timeline links flood basalts to climate change

Wed, 19 Sep 2018 14:49:20 EDT ~ Princeton geologists used tiny zircon crystals found in volcanic ash to rewrite the timeline for the eruptions of the Columbia River flood basalts, a series of massive lava flows that coincided with an ancient global warming period 16 million years ago.

Unprecedented ice loss in Russian ice cap

Wed, 19 Sep 2018 14:49:10 EDT ~ In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study. That dwarfs the ice's previous average speed of about 2 inches per day and has challenged scientists' assumptions about the stability of the cold ice caps dotting Earth's high latitudes.

Moderate warming could melt East Antarctic Ice Sheet

Wed, 19 Sep 2018 13:30:41 EDT ~ Parts of the world's largest ice sheet would melt if Antarctic warming of just 2C is sustained for millennia, according to international research. Scientists used evidence from warm periods in Earth's history to see how the East Antarctic Ice Sheet might react to a warming climate. Find out more...

Mineral weathering from thawing permafrost can release substantial CO2

Wed, 19 Sep 2018 11:58:53 EDT ~ The amount of carbon dioxide released from thawing permafrost might be greater than previously thought, according to a new study by ecologists. The research is the first to document the potential for substantial contributions of CO2 from thawing permafrost to the atmosphere through an inorganic process called mineral weathering.

Origami inspires highly efficient solar steam generator

Wed, 19 Sep 2018 11:14:59 EDT ~ Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. Now, inspired by origami, the Japanese art of paper folding, researchers have devised a solar steam generator that approaches 100 percent efficiency for the production of clean water.

Green space near home during childhood linked to fewer respiratory problems in adulthood

Tue, 18 Sep 2018 18:05:04 EDT ~ Children who have access to green spaces close to their homes have fewer respiratory problems, such as asthma and wheezing, in adulthood, according to new research. In contrast, children who are exposed to air pollution are more likely to experience respiratory problems as young adults. Find out more...
