Antarctica's ice shelves could be melting up to 40% FASTER than we thought

Daily Mail  

Antarctica's ice shelves could be melting up to 40 per cent faster than we thought due to coastal ocean currents, a new study warns. The researchers say this narrow current causes warm water to melt Antarctica's ice shelves – floating platforms of ice around the Antarctic coastline. Antarctica's ice shelves could be melting up to 40 per cent faster than we thought thanks to coastal ocean currents, according to results of a new climate model. Essentially, increased meltwater at the West Antarctic Peninsula can generate climate warming via the Antarctic Coastal Current, which in turn can also escalate melting even at ice shelves thousands of kilometers away from the peninsula.

Melting sea ice in Antarctica causes ocean storms, scientists say

Raw Story  

The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according to a study published Wednesday. Scientists know that the loss of Antarctic sea ice can diminish penguin numbers, cause ice shelves to melt in warmer waters, and impede the Southern Ocean from absorbing carbon dioxide. Using …

Faster melting of West Antarctic ice sheet 'unavoidable’ even if emissions cut

Hindustan Times  

The West Antarctic ice sheet is set to melt faster even if the world rapidly cuts emissions, according to a new study. But an increasing body of research shows that hotter oceans are likely causing the ice shelves around West Antarctica to destabilize, raising the specter of massive sea level rise. Without the shelves’ protection, more of the West Antarctic …
