A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; ...

Rising temperatures of the world's oceans threaten to accelerate the melting and splintering of glaciers—thereby potentially increasing the number of icebergs and, with it, the need to better ...

Now a recent study in the journal Nature Geoscience reveals that such a tipping point may indeed exist. As it turns out, scientists have misunderstood a key aspect of the physical process behind the ...

In 1842, the famous British researcher Michael Faraday made an amazing observation by chance: A thin layer of water forms on the surface of ice, even though it is well below zero degrees. So the ...

As glaciers and ice sheets retreat, they are exposing objects, organisms, and landscapes that have been locked away for ...
