Antarctica's Meltdown May Be Worsening Due to Shifting Wind Patterns

Changing winds at one end of the continent, themselves linked to warming, could be setting off changes that push warm water below the ice at the other end, thousands of miles away.

This image shows the path of the Kelvin waves that interact with the Antarctic Circumpolar Current and push warmer waters under the ice shelves of the West Antarctic Peninsula. Ryan Holmes/NCI
