Canberra, Australia (SPX) Aug 13, 2009 – Tasmania’s east coast is recording its highest-ever winter water temperatures of more than 13 degrees C – up to 1.5 degrees C above normal – due to a strengthening of an ocean current originating north of Australia. Satellites have given oceanographers an insight into a remarkable phenomenon – […]
Warming water and melting land ice have raised global mean sea level 4.5 centimeters (1.7 inches) from 1993 to 2008. But the rise is by no means uniform. This image, created with sea surface height data from the Topex/Poseidon and Jason-1 satellites, shows exactly where sea level has changed during this time and how quickly […]
WASHINGTON, DC, July 29, 2009 (ENS) – Polluted water at American beaches jeopardized the health of swimmers last year and climate change is making conditions worse, according to the 19th annual beachwater quality report released today by the Natural Resources Defense Council. Climate change is expected to further increase the presence of pathogens that cause […]
By Gloria MaenderOctober 2003 The rapid removal of at least half a million great whales from the North Pacific Ocean by intensive industrial whaling more than 50 years ago may have unleashed a complex ecological chain reaction that has since rippled resoundingly from ocean to coastal ecosystems, according to a team of eight scientists, including […]
From Climate Progress: The best evidence is that the climate is now being driven by amplifying feedbacks (see Study: Water-vapor feedback is “strong and positive,” so we face “warming of several degrees Celsius”), most notably: The defrosting of the permafrost The drying of the Northern peatlands (bogs, moors, and mires). The destruction of the […]
‘On left: microscopic photo of the spring diatom bloom with large organisms dominating. On right: warming of six degrees with smaller flagellates dominating.’ Image credit:IFM-GEOMAR, via PhysOrg.com I want to be careful not to exaggerate the significance of this work. That said, I find it disturbing to learn that a warming ocean selects for […]
The Sea Around Us Project investigates the impact of fisheries on the world’s marine ecosystems. This is achieved by using a Geographic Information System (GIS) to map global fisheries catches from 1950 to the present, under explicit consideration of major critical habitats of fish, marine invertebrates, marine mammals and other components of marine biodiversity. North […]
Global ocean temperatures rose to the warmest on record, according to data released last week by the National Oceanic and Atmospheric Administration (NOAA). The combined average global land and ocean surface temperature for June was second-warmest since global recording-keeping began in 1880. NOAA reports that both the Northern and Southern Hemispheres experienced record sea surface […]
By Noreen Parks In addition to weakening Earth’s natural shield against excessive radiation levels, ozone depletion above Antarctica has significantly dampened the Southern Ocean’s ability to absorb atmospheric CO2 and has accelerated acidification of southern polar waters, according to new research reported online June 20 in Geophysical Research Letters (2009, DOI 10.1029/2009GL038227). Of the atmospheric […]
Jane Kay, Chronicle Environment Writer Fluctuating ocean conditions may be depleting the food supply of young sea lions that are turning up skinny and ill on California beaches, mirroring the fate of Brandt’s cormorants earlier this spring. The animal strandings are so numerous that the newly expanded Marine Mammal Center in Sausalito can’t keep up. […]
