Effects of climate change could accelerate by mid-century

Thu, 14 Dec 2017 14:45:22 EST ~ Environmental models are showing that the effects of climate change could be much stronger by the middle of the 21st century, and a number of ecosystem and weather conditions could consistently decline even more in the future. 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.

East Antarctic Ice Sheet has history of instability

Wed, 13 Dec 2017 14:36:50 EST ~ The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet). It's also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink. New research has found that the East Antarctic Ice Sheet may not be as stable as it seems. Find out more...

High-resolution climate models present alarming new projections for US

Wed, 13 Dec 2017 14:36:08 EST ~ Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs will increase the demand on already-strained natural resources like water and energy. Find out more...

Tiny globetrotters: Bacteria which live in the Arctic and the Antarctic

Wed, 13 Dec 2017 12:57:38 EST ~ Geoscientists have compared micro-organisms in the polar regions, noting that some bacteria can be found in both regions of Earth. Find out more...

Human-caused warming likely intensified Hurricane Harvey's rains

Wed, 13 Dec 2017 10:49:58 EST ~ New research shows human-induced climate change increased the amount and intensity of Hurricane Harvey's unprecedented rainfall. Find out more...

Oldest ice core ever drilled outside the polar regions

Wed, 13 Dec 2017 10:46:07 EST ~ The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age -- more than 600,000 years ago, long before modern humans appeared. Find out more...

Sea-level rise projections made hazy by Antarctic instability

Wed, 13 Dec 2017 09:55:45 EST ~ It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new analysis. The study is the first to link global and local sea-level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet. Find out more...

North Sea water and recycled metal combined to help reduce global warming

Wed, 13 Dec 2017 09:55:13 EST ~ Scientists have used sea water collected from Whitby in North Yorkshire, and scrap metal to develop a technology that could help capture more than 850 million tons of unwanted carbon dioxide in the atmosphere. Find out more...
