The new warming trend started in mid-June.
Sea surface temperatures in the Gulf of Alaska are averaging four degrees Fahrenheit warmer than normal. That isn’t as hot or doesn’t extend quite as deep as the original Blob. At least not yet.
If the forecast is accurate, 2019 would be the lowest odd-year pink harvest since 1987. The Department of Fish and Game says the return of warm water temperatures to the North Pacific may have a negative impact on the future survival of pink salmon.
This November has not been promising for snow so far. In general, NOAA data and models call for warmer and wetter conditions this winter in Southeast Alaska.
The blob is gone now, but warm water remains to the north in the Bering Sea. Scientists are pondering potential effects on fish like pollock, which are processed into things like fish sticks and McDonald’s Filet-O-Fish sandwiches.
About 21,000 sockeye were expected back at the Situk River by this time. But only 2,300 fish have made it so far.
The relationship between extreme weather events and climate change is complicated. But scientists are getting closer to figuring out how the two are linked.
Scientists say warm winter weather around the circumpolar north has led to another record-setting year of decreasing sea-ice coverage of the Arctic Ocean. The extent of sea ice formed over this past winter fell short of the previous record-low extent set last year.
Latest surveys indicate that new, young pollock may not have survived warmer ocean temperatures around Kodiak Island.
Biologists and marine researchers are investigating whether warm ocean water is contributing to whale and seabird mortality, marine mammal strandings, sea star wasting disease, paralytic shellfish poisoning and demoic acid.
