West Coast, it could also raise the wildfire danger in California this autumn at the peak of the stateвЂ™s wildfire season. If the marine heat wave continues to expand toward the U.S. вЂњIf these ocean temperatures persist into the fall longer than the atmospheric forcing, I worry that these conditions could intensify any possible tropical storms that might develop in this region.вЂќ вЂњHawaii is literally sitting in the middle of the southern limb of this marine heat wave,вЂќ said University of Washington marine heat wave researcher Hillary Scannell. In the warmest areas, sea surface temperatures have reached about 5.4 degrees Fahrenheit above average.ДЄround Hawaii, the overheated ocean has also contributed to a string of high temperature records on land, including the warmest summer on record for Hawaii. It extends from the Gulf of Alaska down the coast of Western North America and westward to Hawaii. The current marine heat wave covers a horseshoe-shaped area about the size of Alaska. He said the baseline ocean temperatures are warming so fast that scientists are scrambling to keep up with measuring and classifying the events. вЂњWeвЂ™re seeing more intensity in the marine heat waves, higher high temperatures, and that would be more of a function of climate change,вЂќ said Andy Leising, a research scientist at NOAA FisheriesвЂ™ Southwest Fisheries Science Center in La Jolla, California. The halt to crab fishing cost the industry an estimated $100 million. Young salmon had less to eat as they entered the ocean, and thousands of sea lions and seal pups ended up stranded on California beaches. The impacts rippled through ocean ecosystems, with mass die-offs of marine mammals and birds, the closure of crab and clam fisheries and warnings for sardine and anchovy fisheries because of poisoning concerns. The last time the region saw such a widespread and intense вЂњwarm blob,вЂќ in 2014-2015, the unusually warm ocean water boosted the growth of toxin-producing algae and suppressed the growth of small organisms at the base of the ocean food chain. West Coast, and itвЂ™s raising concerns about hurricane risks to the Hawaiian islands and wildfire risks in California. An intensifying marine heat wave in the northeastern Pacific Ocean has triggered government warnings about harm to salmon and other fisheries along the U.S.
