Alarming Decline in Antarctic Ocean Circulation and Oxygen Levels Detected.

Observations show that deep ocean currents around Antarctica are slowing down and deep ocean oxygen levels are declining, happening even earlier than climate models predicted. Melting of Antarctic ice is disrupting the formation of Antarctic bottom water, which drives a global network of ocean currents crucial to keeping Earth's climate stable. The slowdown has the potential to disrupt the connection between the Antarctic coasts and the deep ocean, with profound consequences for Earth's climate, sea level, and marine life. This provides yet another reason to work harder and faster to reduce greenhouse gas emissions.
