The ocean has shielded us from the worst of climate change. Now it is running a fever |

The ocean has been absorbing much of the heat from climate change, but it's now facing severe stress as marine heatwaves have tripled since the 1990s. This surge is wreaking havoc on marine ecosystems, bleaching coral reefs and damaging kelp forests vital for fish populations. While the ocean has acted as a buffer against the worst impacts of climate change, its capacity is being overwhelmed, signaling a critical turning point that demands urgent action to prevent further environmental degradation.
