NASA mission prepares for study of arctic glaciers
Washington, March 19 (ANI): NASA’’s Operation IceBridge mission, the largest airborne survey ever flown of Earth’’s polar ice, is all set to kick off its second year of study of arctic glaciers when NASA aircraft arrive in Greenland on March 22.
The IceBridge mission allows scientists to track changes in the extent and thickness of polar [...]
95 per cent chance that Man is to blame for global warming
London, March 5 (ANI): A new study has found that there is a 95 per cent chance that human activity is to blame for global warming, and only 5 percent chance that the climate change is due to natural factors.
According to a report in the Times, the study was carried out by senior scientists from [...]
Arctic sea ice cover reaches minimum extent for 2009
Washington, September 18 (ANI): A new study has found that the Arctic sea ice cover appears to have reached its minimum extent for this year, the third-lowest recorded since satellites began measuring sea ice extent in 1979.
The study was carried out by researchers from to the University [...]
Arctic could teem with life by 2030 due to global warming
London, July 9 (ANI): In a new study, scientists have said that as global warming removes the Arctic’s icy lid, the region is expected to teem with life by the year 2030.
According to a report in New Scientist, the study of what the Arctic looked like just before dinosaurs were wiped off the planet [...]
NASA spacecraft reveals dramatic thinning of Arctic sea ice
Washington, July 8 (ANI): Data from a NASA Earth-orbiting spacecraft has revealed a dramatic thinning of Arctic sea ice between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record.
The new results provide further evidence for the rapid, ongoing transformation [...]
Scientists see dramatic increase in amount of fresh water in Arctic Ocean
Washington, July 5 (ANI): A new study by scientists has shown a dramatic increase in the amount of fresh water in the Arctic Ocean.
Fresh water flowing into or out of the Arctic Ocean plays an important role in ocean circulation and may be a factor in the response of the world ocean to climate change.
To [...]
Gruelling Arctic mission to study impacts of global warming ends
London, May 14 (ANI): The Catlin Arctic Survey, a gruelling 10-week expedition to measure the thickness of sea-ice that will help study the impacts of global warming in the region, has ended.
According to a report by BBC News, two planes landed [...]
Ozone hole caused increased growth in Antarctic sea ice
Washington, April 22 (ANI): A new research has determined that increased growth in Antarctic sea ice during the past 30 years is a result of changing weather patterns caused by the ozone hole.
The research, done by scientists from British Antarctic Survey (BAS) and NASA, indicates that while there has been a dramatic loss of Arctic [...]
Global warming might reduce if nations cut greenhouse gas emissions by 70 percent
Washington, April 15 (ANI): A new analysis has determined that the threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century.
The analysis was done by scientists at the National Center for Atmospheric Research (NCAR).
While global temperatures would rise, the most dangerous potential aspects [...]
Arctic literally on thin ice, points out new evidence
Washington, April 7 (ANI): New evidence from NASA and satellite observations has shown that the decade-long trend of shrinking sea ice cover in the Arctic is continuing, with the ice cap thinning as well.
In recent years, Arctic sea ice has been declining at a surprising rate.
Scientists who track Arctic sea ice cover from space [...]
Climate change replaces hunting as biggest threat to polar bears
Oslo – Climate change poses the main threat to the world’s polar bear population, the world’s five biggest polar bear nations said Thursday.
Norway, Denmark/Greenland, Russia, the US and Canada all agreed in 1973 to sign an agreement protecting polar bears and their habitat.
But back then, hunting was regarded as the biggest threat to the bears.
However, [...]
Part of Alaska’s coast drifting into sea at twice the rate it has in past
Washington, Feb 21 (ANI): A new study has indicated that part of Alaska’s coast is drifting into the sea at twice the rate it has in the past, reshaping the Arctic shoreline.
The study of the 40-mile (64-kilometer) stretch of coast was published this week in the journal Geophysical Research Letters.
According to a report in National [...]
Arctic sea ice hits second lowest extent during 2008 melt season
Washington, Oct 3: Arctic sea ice extent during the 2008 melt season dropped to the second-lowest level since satellite measurements began in 1979, reaching the lowest point in its annual cycle of melt and growth on September 14.
Preliminary data also indicate 2008 may represent the lowest volume of Arctic sea ice on record.
The declining Arctic [...]
