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 Ice Sheet is likely to tumble into the ocean. Limiting greenhouse gas emissions now can also help control the melting of other ice sheets, including the larger East Antarctic ice sheet, which has the potential to cause 10 times as much sea level rise.

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 …
