Using climatological salinities (World Ocean Atlas available from NOAA NODC at http://www.nodc.noaa.gov) and NOAA SSTOI, we extended this approach to model fields back through 1988 (Figure 2b), revealing regionally averaged Ωar values declining at a rate of about 3% per decade amid considerable seasonal variability. These values are consistent with in situ measurements obtained at […]
By 2050, ocean acidity could increase by 150 percent. This increase is 100 times faster than any change in acidity experienced in the marine environment over the last 20 million years. By Nanet Poulsen 14/12/2009 06:10 The secretariat of the Convention on Biological Diversity (CBD) released Monday a major study in collaboration with the UNEP […]
By Daniel Whitten Jeremy Brown, a fisherman from the Pacific Northwest, is pulling things from the ocean he says are so disturbing that he came to Washington to warn U.S. lawmakers about it. “This is not overfishing, this is something far larger,” said Brown, one of 10 people who met with lawmakers and legislative aides […]
By David Fogarty, Climate Change Correspondent, AsiaCOPENHAGENSat Dec 12, 2009 3:48pm EST COPENHAGEN (Reuters) – More than 250 million people risk losing their livelihoods because of dying tropical coral reefs in what a senior U.N. environmental economist said on Saturday was part of a double climate crisis facing the world. “We forget that there are […]
Report launched from leading marine scientists at Copenhagen summit shows seas absorbing dangerous levels of CO2 By Severin Carrellwww.guardian.co.uk, Thursday 10 December 2009 10.52 GMT The world’s oceans are becoming acidic at a faster rate than at any time in the last 55m years, threatening disaster for marine life and food supplies across the globe, […]
IANS 1 December 2009, 10:20am IST NEW DELHI: In the Sundarbans, surface water temperature has been rising at the rate of 0.5 degree Celsius per decade over the past three decades, eight times the rate of global warming, says a new study. That makes the Sundarbans one of the worst climate change hotspots on the […]
This graph shows the uptake history over the industrial era (ad 1765 to ad 2008) computed from the time-varying inventory. (The corresponding space- and time-varying change in surface disequilibrium of CO2 driving this uptake is also estimated by our inversion method.) There has been a sharp increase in ocean uptake since the 1950s in response […]
Greenhouse gas emissions from vehicles, power stations and industries far to the south are putting shellfish in the Arctic Ocean at risk, an international team reports in the Nov. 20 edition of the journal Science. Acidification may put “some species at risk,” the researchers said, saying this could have a major impact on the entire […]
Fish reared in water acidified by CO2 may become “fatally attracted” to the smell of their predators, say scientists. A team studying the effects of acidification – caused by dissolved CO2 – on ocean reefs found that it leaves fish unable to “smell danger”. Young clownfish that were reared in the acidified water became attracted […]
This graph shows the evolution of the various sources and sinks of anthropogenic CO2 between ad 1765 and ad 2005. Our results indicate that the terrestrial biosphere was a source of Cant until the 1940s, roughly in line with previous model-based estimates3, 18, after which it turned into a sink of anthropogenic CO2. Taken over […]
