Instability of the East Antarctic Ice Sheet signals increased risk of rising sea levels.
Authors of a new study that combine a well-established sea-level rise projection framework plus a model of Antarctic ice-sheet instability suggest in a paper released today that scientists won't be able to determine until the 2060s which of two different sea-level rise scenarios is most likely to occur. Coastal communities should therefore have flexible contingency plans for a range of outcomes by the year 2100, say Robert DeConto of UMass Amherst and Robert Kopp of Rutgers.
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.
Fish cannot see ultraviolet B rays but still change their behavior when they grow up under increased UVB intensity. According to studies by biologists at the University of Bonn on three-spined sticklebacks (Gasterosteus aculeatus), increased UVB leads to a smaller body size and more risk-seeking behavior when faced with predators. Climate change is likely to increase UVB intensity, possibly with consequences for ecosystems and fish farming.
New research shows human-induced climate change increased the amount and intensity of Hurricane Harvey's unprecedented rainfall. The new findings are being published in two separate studies and being presented in a press conference today at the 2017 American Geophysical Union Fall Meeting, along with additional new findings about recent Atlantic Ocean hurricanes.
In a paper in the scientific journal Laser and Particle Beams today, lead author Heinrich Hora from the University of New South Wales in Sydney and international colleagues argue that the path to hydrogen-boron fusion is now viable, and may be closer to realization than other approaches, such as the deuterium-tritium fusion approach being pursued by US National Ignition Facility and the International Thermonuclear Experimental Reactor under construction in France.
Mintek pyrometallurgy engineer Lina Hockaday is trying a highly focused solar reactor to replace the fossil energy used as part of the steelmaking process.
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 published on Dec. 14 in Nature and led by the University of Texas at Austin and the University of South Florida found that the East Antarctic Ice Sheet may not be as stable as it seems.
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 Rutgers University-New Brunswick-led 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.
