Marine heatwaves are prolonged periods of extreme ocean temperatures driven by anthropogenic global warming and phenomena like El Niño. They threaten marine biodiversity, supercharge tropical cyclones, disrupt global food security, and demand urgent climate adaptation and mitigation strategies.

This creates stratification that traps heat, blocks nutrients, harms fisheries, may weaken AMOC, and heighten cyclones and marine heatwaves.

Antarctic meltwater creates a freshwater lid that traps carbon below. This temporary climate buffer exposes model flaws and risks a sudden reversal into a carbon source.
