We are in hot water, thanks Trump!

A new study, published today in the journal Nature, finds that marine heat wave days have doubled between 1982 and 2016, which cannot be explained by natural variability alone. What's new and significant, though, is what the study projects for the future.

Why it matters: Marine species that already live close to the upper end of their heat tolerance could perish in prolonged and more severe marine heatwaves in the near future — much as portions of the Great Barrier Reef did during the 2014 to 2017 global coral bleaching event.

Recent studies have shown that the frequency of marine heat waves has increased in the past several decades, but a lot has remained unknown about these events, until now.
How they did it: The new study uses satellite observations of ocean temperatures during the period from 1982 to 2016, combined with a suite of Earth system computer models to provide more insight into the likelihood and severity of such phenomena. The researchers identified an event as a marine heat wave when the sea surface temperature exceeded its local 99th percentile.

What they found: The study's findings are grim, as they indicate that global warming is already sharply raising the risk of marine heat waves, and this is likely to get significantly worse.

According to Thomas Frölicher, lead author of the study and a researcher at the University of Bern in Switzerland, if greenhouse gas emissions continue on their present course and temperatures were to rise by 6.3°F (3.5°C) by 2100, "the number of marine heatwave days will be 41 times higher than in preindustrial times," he told Axios.

Nature is a prestigious high impact scientific scholarly journal with the highest rep there is, maybe after Cell or Science.

Poor Tom.

Inshore waters are warming up. In my neck of the woods that is evidenced by the lobsters going farther offshore to colder waters, the increase of blue crabs up here from years ago, the decrease in certain needed sea grasses etc. This is something I can attest to. There are some benefits to it though. Oysters are increasing naturally, and a few others. Just my view.

It can be explained, however, by the fact that most of the earlier data is modeled off very limited actual readings

Sea water temps in the 70s off Nauset Cap.
Seem to remember the 50s were normal when I was a youngster.

And sharks are attacking! Thanks Trump.

No that doesn't explain it, or it would not have been published in peer review scholarship in the flagship science journal, it would have instead
been in some blog frequented by...poor Tom.

LOL peer reviewed journals.

Strange because when I read an article about measurements of ocean temperatures being taken by a British Antarctica expedition, their conclusion was precisely along the lines of what I just stated. The ability to take these things is only recent, particularly at depth, and said team also indicated they weren't sure if the warming they noted was due to global warming or the fact that the winds had been pushing warm water in their direction for a sustained period.

Overall though don't you think that the disruption and death of species will move on up the marine food chain -- eventually to us?

They were definitely much cooler Cap. Good memory!
