Greenland’s inland ice is melting far faster than anyone thought
Inland melting of the Northeast Greenland Ice Stream is accelerating — and may contribute far more to sea level rise than earlier estimates suggested.

One 2022 tsunami may have been as tall as the Statue of Liberty
A massive volcanic eruption in the South Pacific, earlier this year, appears to have triggered one tsunami that was initially 90 meters (nearly 300 feet) tall.

Uplifting Antarctic shores point to accelerating loss of glaciers
It appears the Pine Island and “Doomsday” Thwaites glaciers are losing ice — and shrinking faster — than at any time in the past 5,500 years.

Volcanic avalanches may be more destructive than previously thought
Pressures within these pyroclastic flows may be as much as three times as high as observations had suggested.

The ‘Doomsday’ glacier may soon trigger a dramatic sea-level rise
The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.

From icebergs to smoke, forecasting where dangers will drift
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.

Scientists Say: Avalanche
The word avalanche usually refers to a huge snowslide down a mountain, but it can also be used to describe any large mass of material tumbling downhill.
