Global Warming (Page 2)
Arctic sea ice levels to reach record low within daysGuardian Unlimited | 23 Aug 2012
Arctic sea ice is set to reach its lowest ever recorded extent as early as this weekend, in "dramatic changes" signalling that man-made global warming is having a major impact on the polar region.
Marine species at risk unless drastic protection policies put in placeEurekAlert | 22 Aug 2012
Many marine species will be harmed or won't survive if the levels of carbon dioxide continue to increase. Current protection policies and management practices are unlikely to be enough to save them. Unconventional, non-passive methods to conserve marine ecosystems need to be considered if various marine species are to survive.
Improving water quality can help save coral reefsEurekAlert | 20 Aug 2012
Research from the University of Southampton and the National Oceanography Centre, Southampton has found that an imbalance of nutrients in reef waters can increase the bleaching susceptibility of reef corals.
Studying Evolution With an Eye on the FutureNew York Times | 30 Jul 2012
Sinead Collins is creating evolution in her laboratory at the University of Edinburgh to work on solutions to environmental problems like global warming and marine acidification.
Significant sea-level rise in a 2-degree warming worldEurekAlert | 26 Jun 2012
Even if global warming is limited to two degrees Celsius, global-mean sea level could continue to rise, reaching between 1.5 and four meters above present-day levels by the year 2300, with the best estimate being at 2.7 meters, according to a study just published in Nature Climate Change. However, emissions reductions that allow warming to drop below 1.5 degrees Celsius could limit the rise strongly.
Increasing levels of carbon dioxide in Arctic coastal seasScienceDaily.com | 26 Jun 2012
The Arctic coastal seas absorb the greenhouse gas carbon dioxide to an ever-decreasing extent. This leads to an increase in the level in the atmosphere and an increase in the rate of warming in the Arctic.
May 2012 global temperatures second warmest on recordScienceDaily.com | 20 Jun 2012
The globally-averaged temperature for May 2012 marked the second warmest May since record keeping began in 1880. May 2012 also marks the 36th consecutive May and 327th consecutive month with a global temperature above the 20th century average.
Research shows humans are primary cause of global ocean warming over past 50 yearsEurekAlert | 12 Jun 2012
New research by a team of Lawrence Livermore National Laboratory scientists and international collaborators shows that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century.
Biorock giving new life to coral reefsGuardian Unlimited | 08 Jun 2012
Coral reefs are the rainforests of the world's oceans. Like their terrestrial counterparts, they occur in tropical and sub tropical environments, support a bewildering variety of species and are diminishing at an alarming rate. Marine biologists across the world are desperately trying to protect our remaining reefs from the impacts of global warming and destructive fishing.
Arctic melt releasing ancient gasBBC | 20 May 2012
Scientists identify thousands of sites in the Arctic where methane stored for millennia is bubbling out, potentially accelerating global warming.
Arctic seabirds adapt to climate changeScienceDaily.com | 16 May 2012
The planet is warming up, especially at the poles. How do organisms react to this rise in temperatures? Biologists have now shown that little auks, the most common seabirds in the Arctic, are adapting their fishing behavior to warming surface waters in the Greenland Sea. So far, their reproductive and survival rates have not been affected. However, further warming could threaten the species.
Study Indicates a Greater Threat of Extreme WeatherNew York Times | 27 Apr 2012
New research suggests that global warming is causing the cycle of evaporation and rainfall over the oceans to intensify more than scientists had expected, an ominous finding that may indicate a higher potential for extreme weather in coming decades.
Study finds surprising Arctic methane emission sourceScienceDaily.com | 26 Apr 2012
The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study has uncovered a surprising and potentially important new source of Arctic methane: the ocean itself.
Sea change in salinity heralds shift in rainfallReuters | 26 Apr 2012
SINGAPORE (Reuters) - Scientists have detected a clear change in salinity of the world's oceans and have found that the cycle that drives rainfall and evaporation has intensified more than thought because of global warming.
