Earth's 'catastrophic' ice melt problem is worse than previously thought, study says The world's two gigantic ice sheets are in greater peril from global warming than previously thought, a study ...

Ice sheet melting is the dominant contributor to rising seas and the rate of annual sea level rise has doubled over the past 30 years. It’s set to get worse.

Beneath the icy façade of the 760,000-square-mile West Antarctic Ice Sheet (WAIS) bubbles a hotbed of 100 active volcanoes is kept restrained by the thick layer of ice. But as the icy blanket melts ...

The West Antarctic Ice Sheet is in a vulnerable position, but the situation may be less dire than initially believed. Scientists have been eyeing the West Antarctic Ice Sheet, or WAIS, for some time ...

Greenland ice sheet retreat across temperature thresholds, with ice loss beyond the 3.4°C tipping point. Grey shading represents areas experiencing glacial isostatic adjustment.

For example, if an ice sheet 1-kilometer thick (0.6 miles) melts in 300 years rather than 3,000, an extra 50 million tons of material escapes, the models suggest.

Why does any of this matter? Scientists report that human activity has so far raised global temperatures by 1.2C relative to late 1700s benchmarks. Experts warn that the West Antarctic Ice Sheet (WAIS ...

The West Antarctic Ice Sheet (WAIS), which is experiencing rapid ice loss, is a major contributor to rising sea levels. Wahlin said the WAIS is "a massive amount of ice - it would be dramatic if ...

They examined sediment from the bottom of an ice core — dubbed GISP2 — extracted from two miles below the surface at the center of the ice sheet nearly 30 years ago.

“This is missing physics, which isn’t in our ice sheet models. They don’t have the ability to simulate melting beneath grounded ice, which we think is happening," Bradley said.

Collapse of the WAIS represents over 5 meters of potential global sea level rise, so understanding the melting of the ice sheet is critical for forecasting how much and how fast seas will rise ...

The West Antarctic Ice Sheet is considered particularly vulnerable to warming temperatures and may be headed towards irreversible collapse under future climate change trajectories. The ice sheet’s ...
