Benefits and risks for marine life from CO2 removal approaches
University of Tasmania Institute for Marine and Antarctic Studies (IMAS)
Published: 20 January 2026
IMAS researchers analyzed how different marine climate engineering methods -- from ocean alkalinity enhancement to iron fertilization -- could alter ocean chemistry and reshape marine ecosystems, finding that no approach is free of ecological consequences.

Weak self-induced cooling of tropical cyclones amid fast sea surface warming
Ocean University of China
Published: 8 January 2026
Using global drifter data, OUC researchers found that tropical cyclone inner-core cooling is far weaker than satellite estimates suggest, while storm-local SSTs are rising at twice the regional average -- implying future TC intensity may be underestimated.

Why the eutrophicated Baltic Sea struggles with recovery
Leibniz Institute for Baltic Sea Research (IOW)
Published: 19 February 2026
A comprehensive IOW review reveals how internal phosphorus recycling from anoxic sediments nearly offsets decades of nutrient load reductions, explaining why algal blooms and oxygen depletion persist despite 50% cuts in phosphorus inputs.
