Melting sea ice in Antarctica causes ocean storms, scientists say

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 …
