- Antarctic sea ice has declined rapidly since 2016, a shift scientists say has triggered a dramatic change in a crucial part of Earth's climate system.
- Southern Ocean: A paper published Wednesday documented a sharp salinity increase in a vast layer extending from 2,300 to 4,000 feet deep.
Why it matters: The finding ties Antarctic sea ice loss since 2016 to a measured salinity increase in a Southern Ocean layer 2,300 to 4,000 feet deep. Scientists describe it as a dramatic shift in a crucial part of Earth's climate system, so the ice decline is already registering as a change in ocean structure far below the surface.
