A decade-old marine heat wave offered a chilling preview of ocean changes to come
Ten years after a marine heat wave decimated ecosystems off California’s coast, researchers warn that such events, exacerbated by climate change, are becoming the new norm.
Delger Erdenesanaa reports for The New York Times.
In short:
- A 2014 marine heat wave called "the Blob" disrupted ecosystems along the California coast, wiping out 90% of kelp forests and starving millions of seabirds and marine species.
- Scientists now see the Blob as a harbinger of extreme ocean warming, with similar "super-marine heat waves" becoming more frequent and globally widespread in recent years.
- Restoration efforts, like kelp reseeding and habitat monitoring, aim to repair damaged ecosystems, but challenges from ongoing warming and species loss persist.

Why this matters:
With rising global temperatures, marine heat waves like this are no longer rare disruptions; they’re becoming frighteningly common. Ocean waters are heating faster than scientists predicted, destabilizing ecosystems already struggling under the weight of overfishing, pollution, and acidification. Read more: Surprise! Unexpected ocean heat waves are becoming the norm.
