Coastal cities from Miami to Mumbai sit on land that would vanish beneath the ocean if Earth’s two largest ice sheets, Greenland and Antarctica, surrendered all their frozen mass. The combined result, ...

If the ice blanketing Antarctica were to vanish, the world’s shorelines would be redrawn so radically that some countries would simply cease to exist. Entire coastal megacities would be abandoned, new ...

Melting glaciers and ice sheets are raising sea levels while the Arctic is poised to log one of its worst winters on record. Here are some key points about the planet's ice as human-induced global ...

An ice dome in northern Greenland once melted completely at temperatures the region could experience again this century, a finding that will begin to paint a more accurate picture of how fast the ...

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 ...

Antarctic ice-shelf melt constitutes a major source of epistemic uncertainty in future sea level rise, yet the interplay between melt and ocean circulation is not captured in climate model projections ...

Scientists drilling deep beneath Greenland’s ice have uncovered a startling clue about its past—and future. Evidence shows that the Prudhoe Dome, a major high point of the ice sheet, completely melted ...

The Arctic landscape is changing at an unprecedented rate. In addition to rising temperatures, climate change is causing episodes of extreme melting, which occurs when ice losses that previously took ...
