Extra Arctic observations can improve predictability of tropical cyclones

Fri, 21 Sep 2018 09:24:27 EDT ~ Scientists have found that additional weather observations in the Arctic can help predict the track and intensity of tropical and mid-latitude cyclones more accurately, improving weather forecasting of extreme weather events. Find out more...

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...

NASA balloon mission captures electric blue clouds

Thu, 20 Sep 2018 16:08:45 EDT ~ Scientists share mesmerizing new images of electric blue clouds from NASA's PMC Turbo balloon mission that flew in over the Arctic in July 2018. 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...

Climate change modifies the composition of reefs

Thu, 20 Sep 2018 10:11:10 EDT ~ Corals devastated by climate change are being replaced naturally by other species such as gorgonians, which are less efficient in acting as a carbon sink. A study has analyzes for the first time why gorgonians are more resistant than corals to human impacts and global climate change. 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...

Scientists identify three causes of Earth's spin axis drift

Wed, 19 Sep 2018 19:59:06 EDT ~ Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin axis drift -- contemporary mass loss primarily in Greenland, glacial rebound, and mantle convection.

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.
