'Weedy' fish species to take over our future oceans

2017-07-06 06:00:00| LifeSciencesWorld

[NEWS] University of Adelaide researchers have for the first time demonstrated that the ocean acidification expected in the future will reduce fish diversity significantly, with small 'weedy' species dominating marine environments. Published today in Current Biology, the researchers studied species interactions in natural marine environments at underwater volcanic vents, where concentrations o…

Oceans act as 'heat sink'

2016-11-22 13:00:00| LifeSciencesWorld

[NEWS] A new multi-institutional study of the so-called global warming “hiatus” phenomenon — the possible temporary slowdown of the global mean surface temperature (GMST) trend said to have occurred from 1998 to 2013 — concludes the hiatus simply represents a redistribution of energy within the Earth system, which includes the land, atmosphere and the ocean. In a paper published today in Earth's Future, a journal of the American Geophysical Union, lea…

Known types of viruses in worlds oceans tripled

2016-09-22 07:28:00| Climate Ark Climate Change & Global Warming Newsfeed

Financial Express: Scientists have tripled the known types of viruses -- identifying over 15,000 distinct ones -- living in the world`s oceans, an advance that may be key to the efforts to protect the planet from global warming. Greenhouse gases threatening the environment could be mediated by these viruses through manipulation by scientists -- something that is at least a couple decades off, but will likely be necessary to manage climate change, researchers said. The study, led by Ohio State University in the...
