A study of intertidal ecosystems across North and South America found that trematode parasites are more abundant in cooler temperate waters than near the equator, challenging the latitudinal diversity gradient.

Ocean warming drives melting of Antarctic sea ice

Published: 18 March 2026
A Nature Climate Change study reveals Antarctic sea ice loss since 2015 is driven by ocean warming that thinned a cold protective water layer, allowing warm deep water to accelerate melting after strong 2015 storms.

Scientists reveal the surprising origins of Earth's largest oceanic engine
Imperial College London
Published: 7 April 2026
Climate simulations show the Antarctic Circumpolar Current formed through glaciation and wind changes rather than ocean gateway openings alone, fundamentally changing our understanding of how Antarctica's ice sheet and this giant current co-evolved.
