The Blob Is Back—5,000-Mile Heatwave Hits North Pacific
• A massive marine heatwave, 'the Blob,' has returned, stretching 5,000 miles across the North Pacific.
• The Blob's warm waters threaten marine ecosystems, fisheries, and weather patterns in the Pacific Northwest.
• This heatwave could intensify atmospheric rivers and reduce mountain snowfall, leading to potential flooding and water scarcity.
Massive marine heatwave returns to North Pacific
The Blob, a significant marine heatwave, has resurfaced in 2025, extending nearly 5,000 miles across the North Pacific from Japan to the U.S. West Coast. This resurgence marks the fourth-largest instance of the Blob observed in the Northeast Pacific, raising considerable alarm among scientists and environmentalists. The unusually warm waters are poised to influence weather patterns, intensify atmospheric rivers, and reduce mountain snowfall, potentially leading to significant disruptions across the Pacific Northwest.
