First evidence of surprising ocean warming around Galápagos corals

Wed, 21 Feb 2018 00:00:00 EST

(University of Arizona) A new analysis of the natural temperature archives stored in coral reefs shows the ocean around the Galápagos Islands has been warming since the 1970s. The finding surprised the research team, because the sparse instrumental records for sea surface temperature for that part of the eastern tropical Pacific Ocean did not show warming. Scientists thought strong upwelling of colder deep waters spared the region from the warming seen in other parts of the Pacific.



'Chameleon' ocean bacteria can shift their colors

Wed, 21 Feb 2018 00:00:00 EST

(University of Warwick) Cyanobacteria -- which propel the ocean engine and help sustain marine life -- can shift their color like chameleons to match different colored light across the world's seas, according to research by an international collaboration including the University of Warwick.



Under projected rates of sea level rise, a bleak future for Pacific coast tidal wetlands

Wed, 21 Feb 2018 00:00:00 EST

(American Association for the Advancement of Science) Pacific coast marshes, particularly those in California and Oregon, are highly vulnerable to climate change, according to a new modeling analysis. Under higher-range sea level rise scenarios estimated to impact this region by the end of the century, all high- and mid-marsh habitats are projected to be lost. Only the low marsh habitat is likely to survive under such



Sea urchins erode rock reefs, excavate pits for themselves

Wed, 21 Feb 2018 00:00:00 EST

(PLOS) Through their grazing activity, sea urchins excavate rock and form the pits they occupy. This activity may cause significant bioerosion of temperate reefs, according to a study published Feb. 21, 2018 in the open-access journal PLOS ONE by Michael Russell from Villanova University, US, and colleagues.

Sea-level legacy: more rise for each delay in peaking emissions

Tue, 20 Feb 2018 00:00:00 EST

(Potsdam Institute for Climate Impact Research (PIK)) Peaking global CO2 emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2 degrees C. A study now published in the journal Nature Communications analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement.

Don't blame hurricanes for most big storm surges in northeast

Thu, 15 Feb 2018 00:00:00 EST

(Rutgers University) Hurricanes spawn most of the largest storm surges in the northeastern US, right? Wrong, according to a study by Rutgers University-New Brunswick scientists. Extratropical cyclones , including nor'easters and other non-tropical storms, generate most of the large storm surges in the Northeast, according to the study in the Journal of Applied Meteorology and Climatology. They include a freak November 1950 storm and devastating nor'easters in March 1962 and December 1992.
