US EditionOcean and River Heat Waves Intensify, Threatening Aquatic Life
River heat waves in the U.S. increased by 1.8 events per year since 1980, rising two to four times faster than air heat waves, threatening aquatic ecosystems.
- An unprecedented and extensive marine heat wave is currently affecting the Pacific Ocean, spanning roughly 5,000 miles from the region near Japan across to the U.S. West Coast.
- Oceanographer Art Miller attributes this heat wave and its associated blobs to persistent anomalous wind patterns linked to global warming from fossil fuel emissions.
- This phenomenon is identified as the fourth most extensive marine heat anomaly in the Northeast Pacific and has been linked to several instances of mass mortality among marine mammals, seabirds, and small fish species in Alaska’s coastal regions during the summer months.
- Michael McPhaden stated the North Pacific warmed fastest globally over the past decade, and wildlife biologist Heather Renner reported an uptick in public calls about sick and dead birds.
- Researchers warn that repetitive marine heat waves and increasing ocean warming threaten coastal ecosystems and could significantly affect regional weather and marine life if trends continue.

Oceans could reach a dangerous tipping point by 2050
UC Santa Barbara researchers project that human impacts on oceans will double by 2050, with warming seas and fisheries collapse leading the charge. The tropics and poles face the fastest changes, and coastal regions will be hardest hit, threatening food and livelihoods worldwide.
As the Zaragozans, orensans, know to a lesser extent the Sevillians and everyone who has one nearby, when the heat tightens, the river remains a climate refuge. However, this begins to change. By studying the impact of the heat waves since 1980 on more than 1,400 river courses, American researchers have discovered that these extreme events are increasing at a rate that quadruples that of the atmospheric ones. The work, published in the magazine …
