The Big Picture
Polar ice, ocean heat, sea ice, circulation systems, and sea-level dynamics are showing signs of accelerating change and possible threshold behavior. This issue covers the linked risks from Antarctic and Greenland ice loss, AMOC weakening, ocean warming, and coastal sea-level exposure.
Ocean and cryosphere instability drives long-term sea-level rise, coastal retreat, extreme flooding, global circulation changes, carbon-cycle feedbacks, and security risks. These systems are slow to reverse and high-consequence, making them central to long-term climate intelligence.
