Enhanced warming subtropical ocean is expanding the tropics

Published: 23 September 2020
AWI researchers show that warming subtropical oceans—not atmospheric changes—are driving the expansion of the tropics. Ocean gyres amplify surface warming, shifting tropical boundaries and increasing drought risk in regions like California and Australia.

The future of krill

Published: 15 October 2020
Krill is vital to the Antarctic ecosystem and increasingly targeted by fisheries. AWI researchers warn current catch limits may not protect krill populations. New data, tech, and international coordination are key to sustainable management.

Depths of the Weddell Sea are warming five times faster than elsewhere

Published: 19 October 2020
Deep waters of the Weddell Sea have warmed five times faster than the global ocean average over 30 years, driven by shifting winds and currents—threatening Antarctic Bottom Water formation and global ocean circulation.
