The Pacific Ocean is the hottest it’s been in a century. A vast marine heat wave – nicknamed “the blob” – is back, and it’s bigger than ever. Once confined to the northeast Pacific, this year’s blob now spans the entire ocean basin, stretching nearly 5,000 miles (8,000 km) from Japan to California. The water is so abnormally hot that Japan experienced its highest temperature on record – 107.2°F (41.8°C). And on the U.S. West Coast, that heat is fueling humidity, disrupting winds, and threatening to reshape the coming winter’s weather. This isn’t just a warm patch. It's the most expansive marine heat wave ever recorded in the North Pacific for August, with sea surface temperatures smashing century-old records. And scientists are worried. Repeated events like this suggest something deeper: the North Pacific is warming faster than any other ocean on Earth, supercharged by greenhouse gases and shifting wind patterns that suppress the natural upwelling of cooler water from below. That’s bad news for marine life. In 2015, a similar blob led to massive die-offs of seabirds, sea lions, and fish in Alaska. This year, smaller but widespread deaths are already being reported. Many species, like the common murre, still haven’t recovered from past heat waves. If this one sticks around, the damage could deepen.
