Tidal action on the underside of the Thwaites Glacier in the Antarctic will "inexorably" accelerate melting this century, according to new research by British and American scientists. The researchers warn the faster melting could destabilize the entire West Antarctic Ice sheet,

"Thwaites has been retreating for more than 80 years, accelerating considerably over the past 30 years, and our findings indicate it is set to retreat further and faster," Rob Larter, science coordinator of ITGC and a marine geophysicist at the British Antarctic Survey (BAS), said in a statement.

The Doomsday Glacier has been melting at an increasing rate as global temperatures continue to rise, but a new analysis suggests Thwaites could be in for even faster melting than previously believed.

Tidal action pumping warmer sea water on the underside of the massive Thwaites Glacier will “inexorably” accelerate its melting this century, which could lead to the collapse of the entire West Antarctic ice sheet and seriously impact global sea levels,

New study reveals Thwaites Glacier melting much faster than expected. Collapse could trigger devastating sea level rise.

After years of research, scientists studying the massive Thwaites Glacier have found little reason for optimism.

A new science briefing has revealed there is a "grim outlook" for Thwaites Glacier in Antarctica, also known as the 'Doomsday Glacier', which if it melts could plunge parts of the world underwater. Thwaites Glacier is a vast area of the West Antarctic Ice Sheet and is the same size as Great Britain or the US state of Florida.
