Exceptional rise in ancient sea levels revealedScienceDaily.com | 06 Jun 2012
Since the end of the last ice age 21,000 years ago, our planet has seen ocean levels rise by 120 meters to reach their current levels. This increase has not been constant, rather punctuated by rapid accelerations, linked to massive outburst floods from the ice caps. The largest increase, known by paleoclimatologists as 'Melt-Water Pulse 1A', proved to be enigmatic in many respects.
Australian project simulates climate changeGuardian Unlimited | 14 May 2012
Multimillion-dollar study subjects bushland to heightened CO2 levels and altered rainfall patternsAn Australian university has embarked upon an ambitious project - hailed as the first of its kind in the world – to simulate how the environment would cope with runaway climate change.The decade-long...
New weak point discovered in the Antarctic ice sheetScienceDaily.com | 11 May 2012
The Filchner-Ronne Ice Shelf fringing the Weddell Sea, Antarctica, may start to melt rapidly in this century and no longer act as a barrier for ice streams draining the Antarctic Ice Sheet, new research shows.
Gaseous emissions from dinosaurs may have warmed prehistoric EarthScienceDaily.com | 10 May 2012
Sauropod dinosaurs could in principle have produced enough of the greenhouse gas methane to warm the climate many millions of years ago, at a time when the Earth was warm and wet. That's according to calculations reported in the May 8 issue of Current Biology, a Cell Press publication.
Effect of groundwater use: Using water from wells leads to sea level rise, cancels out effect of dam...ScienceDaily.com | 10 May 2012
As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn't just seep back into the ground -- it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world's oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year.
Club of Rome sees 2 degree Celsius rise in 40 yearsReuters | 08 May 2012
LONDON (Reuters) - Rising carbon dioxide emissions will cause a global average temperature rise of 2 degrees Celsius by 2052 and a 2.8 degree rise by 2080, as governments and markets are unlikely to do enough against climate change, the Club of Rome think tank said.
European slump leads utilities to burn more coalReuters | 08 May 2012
LONDON (Reuters) - Europe's economic slump is allowing utilities in some countries to burn increasing amounts of cheap, highly polluting coal for electricity generation and still meet legally binding targets to cut carbon dioxide emissions, Reuters research shows.
Stalagmite research suggests Earth has two modes of responding to changeScienceDaily.com | 04 May 2012
By analyzing stalagmites, a team of researchers has determined that the climate signature in the tropics through four glacial cycles looks different in some ways and similar in others when compared to the climate signature at high latitudes. The results suggest that Earth's climate system might have two modes of responding to significant changes.
Greenland glaciers speed up, swelling rising seas: reportsReuters | 03 May 2012
WASHINGTON (Reuters) - Some of Greenland's glaciers are moving about 30 percent faster than they did 10 years ago, contributing to rising global sea levels, but that still may not be enough to reach the most extreme projections for 2100, scientists reported on Thursday.
Sea-level rises 'may not be as high as worst-case scenarios have predicted'Guardian Unlimited | 03 May 2012
Sea-level rises are unlikely to be as high as worst-case scenarios have forecasted, suggests new research which shows that Greenland's glaciers are slipping into the sea more slowly than was previously thought. But the scientists warned that ice loss still sped up by 30% and is driving rises in sea levels that endanger low-lying coasts around the world.
'Warming hole' delayed climate change over eastern United StatesScienceDaily.com | 27 Apr 2012
Climate scientists have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United States -- that is, a cold patch where the effects of global warming were temporarily obscured. The findings have implications for industrial nations (like China) that have not yet tightened air quality regulations.
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.
Northern Canada feels the heat: Climate change impact on permafrost zonesScienceDaily.com | 26 Apr 2012
As climate change in the near future is likely to bring raised temperatures at northern latitudes, the characteristics of permafrost could greatly change. Changes to permafrost could have serious impact on existing and future northern infrastructures such as pipelines and could significantly affect...
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.
Carbon dioxide was hidden in the ocean during last Ice AgeScienceDaily.com | 30 Mar 2012
Why did the atmosphere contain so little carbon dioxide during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study based on newly developed isotope measurements.
Scientists pin down historic sea level riseReuters | 28 Mar 2012
LONDON (Reuters) - The collapse of an ice sheet in Antarctica up to 14,650 years ago might have caused sea levels to rise between 14 and 18 metres (46-60 feet), a study showed on Wednesday, data which could help make more accurate climate change predictions.
