How the ice ages ended
A study of sediment cores collected from the deep ocean supports a new explanation for how glacier melting at the end of the ice ages led to the release of carbon dioxide from the ocean.

Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French ...

The three largest glaciers in Greenland—which hold enough frozen water to lift global sea levels some 1.3 metres—could melt faster than even the worst-case warming predictions, research published Tuesday showed.

(Phys.org) -- Over the past several years, additive manufacturing has become the golden child of process engineering. This is because it allows parts to be made faster, more cheaply and in some cases to be made at all. Now ...
A record start to summer ice melt in Greenland this year has drawn attention to the northern ice sheet. We will have to wait to see if 2019 continues to break ice-melt records, but in the rapidly warming Arctic the long-term ...
