Korallenriffe in der Klimakrise

Coral reefs cover less than 0.2% of the ocean but house 30% of all marine species.

That's like cramming the population of New York into a single neighborhood. Here's the problem.

When water temps rise just half a degree above 28°C, corals kick out their colorful algae

partners and turn ghostly white. This bleaching isn't just cosmetic. It's a breakup that

kills the coral within weeks. These algae provide up to 95% of the coral's food through

photosynthesis. Without them, corals starve. Think of it like your stomach suddenly

rejecting all food. The ocean absorbs excess CO2, making water more acidic,

which weakens coral skeletons like dissolving chalk in vinegar. Since the 1980s, 19% of reefs have
