Climate change is having a dramatic effect on Antarctic sea ice. For years, ice around the continent seemed oddly consistent, while sea ice in the Arctic has declined dramatically. But that is no longer the case. Over the last few years, the seasonal sea ice coverage in Antarctica has declined precipitously. In 2023, we had the smallest sea ice maximum on record and warming ocean waters are likely to continue this trend.
A new short documentary by John Weller at Only One, PAL Co-PI Sharon Stammerjohn explains how the sea ice coverage around Antarctica has changed over the years, and how warming ocean waters are likely to impact sea ice and local ecosystems in the future.
