Last January, a study in Nature Climate Change showed the world's glaciers are the smallest they've been in human history, revealing radiocarbon material that hasn't been exposed for 40,000 years. Now, new research published in Nature quantifies how much the world's lost glaciers have contributed to rising sea levels. From …
Helping developing nations to adapt to climate change such as floods or heatwaves can give bigger economic benefits than a focus on deep cuts in greenhouse gas emissions, a study indicated on Friday. A total of $10 trillion spent on adaptation, ranging from research into drought-resistant crops to measures to …
health Side-effects stay Chemicals called contrast agents used during cardiac angiography can seriously damage kidneys which, in turn, increases chances of heart attacks. Side-effects were earlier thought to be temporary. A team tracked 294 patients exposed to contrast agents for a year. 31 per cent of the patients were found …
With their focus on greenhouse gases, atmospheric scientists have largely overlooked lowly soot particles. But black carbon is now a hot topic among researchers and politicians. Jeff Tollefson investigates.
Pacific islands are trying low-cost ways to protect crops and coasts from cyclones that are a bigger threat -- for now -- than rising sea levels that could wipe low-lying nations off the map. Pacific island delegates at June 1-12 talks in Bonn working on a new U.N. climate treaty …
In the debate over global warming, one thing is clear: as the planet gets warmer, sea levels will rise. But how much, where and how soon? Those questions are notoriously hard to answer. Scientists at the National Center for Atmospheric Research, in Boulder, Colo., are now adding to the complexity …
New York, Boston and other cities on North America's northeast coast could face a rise in sea level this century that would exceed forecasts for the rest of the planet if Greenland's ice sheet keeps melting as fast as it is now, researchers said on Wednesday. Sea levels off the …
Global warming conjures images of rising seas that threaten coastal areas. But in Juneau, as almost nowhere else in the world, climate change is having the opposite effect: As the glaciers here melt, the land is rising, causing the sea to retreat. The geology is complex, but it boils down …
Coastal states have now made their bids for vast new areas of continental shelf You never know what may come in handy. That is the principle behind the rush for the seabed that reached a climax of sorts this week with the deadline on May 13th for lodging claims to …
Sea levels are rising twice as fast as had been thought SCIENCE and politics are inextricably linked. At a scientific conference on climate change held this week in Copenhagen, four environmental experts announced that sea levels appear to be rising almost twice as rapidly as had been forecast by the …
Mathematical modelling and time series analysis techniques are important tools for extracting information from complex geotime series. These techniques also facilitate a fair degree of prediction, which is one of the prime goals of science. The data analysis strategy for such a purpose mainly involves spectral analysis and pattern classification. …
Surface meltwater that reaches the base of an ice sheet creates a mechanism for the rapid response of ice flow to climate change. The process whereby such a pathway is created through thick, cold ice has not, however, been previously observed. We describe the rapid (<2 hours) drainage …
Sea-level rise (SLR) due to climate change is a serious global threat: The scientific evidence is now overwhelming. The rate of global sea level rise was faster from 1993 to 2003, about 3.1 mm per year, as compared to the average rate of 1.8 mm per year from 1961 to …

A fast melt of ice from the Andes to the Arctic should be a wake-up call for governments to work out a strong new United Nations treaty this year to fight climate change, Norway said on Tuesday. Foreign Minister Jonas Gahr Stoere, starting two-day talks of the eight Arctic nations …
A study of Greenland's icesheet has revealed that a vast store of planet-warming methane appears to be more stable than thought, easing fears of a rapid rise in temperatures, a scientist said on Friday. Methane is about 25 times more powerful at trapping heat in the atmosphere than carbon dioxide …
The UN Climate Panel says seas could rise by 18-59 cms (7-24 inches) by 2100, without taking account the possible acceleration of a melt of ice sheets in Antarctica or Greenland. Even a small thaw of Antarctica and Greenland would affect sea levels since together they lock up enough ice …
Some Scientific Models Go A Step Further, Predict Large Portion Of Ice Could Disappear In 11 Years Washington: Some 80% of Arctic ice may disappear in 30 years, not 90 as scientists had previously estimated, according to a new study on the impact of global warming.
