Scientists from the International Thwaites Glacier Collaboration warn of a "grim outlook" for the Thwaites Glacier, also known as the "Doomsday Glacier."

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

The research team, using ice-breaking ships and underwater robots, determined the iceberg is melting at an accelerating rate.

If the Thwaites Glacier melted entirely, experts said it would raise sea levels by 3.3 metres, enough to put Westminster, Battersea and Canary Wharf underwater.

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,

A glacier known as ‘the doomsday glacier’ that has the potential to cause sea levels to rise across the planet could be on the verge of collapse, scientists have warned. Researchers from the British Antarctic Survey (BAS) used underwater robots to take new measurements of the Thwaites Glacier,

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.
