Impact of polar ozone depletion on subtropical precipitation

Impact of polar ozone depletion on subtropical precipitation

The ozone hole over Antarctica has been rearranging rainfall patterns throughout the Southern Hemisphere for decades, a new modeling analysis shows. The idea that losing ozone in the cold stratosphere over the South Pole could affect weather in the lower atmosphere…

Arctic Ocean freshwater will cause ‘unpredictable changes on climate’

Arctic Ocean freshwater will cause ‘unpredictable changes on climate’

A vast expanse of freshwater in the midst of the Arctic Ocean is set to wreak unpredictable changes on the climate in Europe and North America, new scientific analysis has shown.The water – comprising meltwater from the ice cap and run off from rivers – is at

Russian boreal forests undergoing vegetation change

Russia’s boreal forest – the largest continuous expanse of forest in the world, found in the country’s cold northern regions – is undergoing an accelerating large-scale shift in vegetation types as a result of globally and regionally warming climate.That in turn is

Arctic ocean show significant increase in freshwater content

Arctic ocean show significant increase in freshwater content

Since the 1900, the freshwater content of the upper Arctic Ocean has increased by about 20 %. This corresponds to a rise of approx. 8,400 cubic kilometres and has the same magnitude as the volume of freshwater annually exported on average from this marine region in

2011 arctic ice extent is down

2011 arctic ice extent is down

The 2011 maximum extent of Arctic sea ice appears to be tied for the lowest amount in area since satellite measurements began 32 year ago.Researchers at the University of Colorado Boulder said the maximum ice extent was 463,000 square miles below the 1979-2000

New deep-sea volcanic vents found in Antarctic’s Southern Ocean

New deep-sea volcanic vents found in Antarctic’s Southern Ocean

British researchers say the discovery of deep-sea volcanic vents in the Antarctic’s Southern Ocean suggests they’re more common than previously thought.

Deep-sea vents are hot springs on the seafloor, where mineral-rich water nourishes colonies of
