For polar bears, it's survival of the fattest
One of the most southerly populations of polar bears in the world – and the best studied – is struggling to cope with climate-induced changes to sea ice, new research reveals. Based on over 10 years' ...
Significant contribution of Greenland's peripheral glaciers to sea-level rise
The scientists looked at glaciers which behave independently from the ice sheet, despite having some physical connection to it, and those which are not connected at all.
Warmer climate boosts northern crops but the bad soon outweighs the good
Climate change is creating warmer growing conditions in parts of the Earth's northern regions, a new study has found, but experts warn that drought and heat wil soon cancel out the agricultural benefits.
What can 'ring species' teach us about evolution?
Ten thousand years ago, at the end of the last ice age, a species of greenish warblers lived in a forest south of the Tibetan Plateau. As the ice receded, the forest grew to form a ring around the plateau—and so did the ...
Tracers reveal hidden rivers beneath ice-sheet
Artificial gas tracers pumped into water at the surface of the Greenland ice sheet have revealed a hidden network of rivers flowing beneath it.
Bedmap2 gives scientists a more detailed view of Antarctica's landmass
Scientists at the British Antarctic Survey have been working with a host of international collaborators to present the most detailed map yet of Antarctica's landmass. Bedmap2 reveals a landscape of mountain ...
Earth is warmer today than during 70 to 80 percent of the past 11,300 years
Using data from 73 sites around the world, scientists have been able to reconstruct Earth's temperature history back to the end of the last Ice Age, revealing that the planet today is warmer than it has been ...
Glaciers will melt faster than ever and loss could be irreversible, warn scientists
Canada's Arctic Archipelago glaciers will melt faster than ever in the next few centuries. Research by European funded scientists has shown that 20 per cent of the Canadian Arctic glaciers may have disappeared by the end ...
The making of Antarctica's hidden fjords
Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists.
Study finds evidence of bacteria spread throughout the global ocean
Arctic ice loss amplified Superstorm Sandy violence
(Phys.org) —If you believe that last October's Superstorm Sandy was a freak of nature—the confluence of unusual meteorological, atmospheric and celestial events—think again.
Astronomers open window into Europa's ocean
(Phys.org) —With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown—known as the Pluto killer for discovering a Kuiper-belt object ...
NASA Goddard lab works at extreme edge of cosmic ice
(Phys.org) —Behind locked doors, in a lab built like a bomb shelter, Perry Gerakines makes something ordinary yet truly alien: ice. This isn't the ice of snowflakes or ice cubes. No, this ice needs such ...
