How China’s Massive Fishing Fleet Is Transforming the World’s Oceans
https://slate.com/news-and-politics/2020/09/beijing-fishing-fleet-subsidies-north-korea.html

The tragedy of the commons seems alive and well and one of the factors preventing us from powering down.

Too much wealth (even if most of it is in the form of trickets, mostly made in China, but designed in the USA.)

The Coronavirus is teaching us what it's like to power down, but will we learn?

Anyone see any learning we are getting from that experience? I don't see any.

The vast majority of humans will never make any sacrifices if they are not forced to do so. For now, the world can delude itself that resources will be there as needed and that the toilet for pollution and waste consisting of the atmosphere, the oceans and land is infinite. But in the coming few decades this bubble of delusion will be ruthlessly burst by reality. Then we will have most likely some insane scramble that will achieve nothing. I expect lots of scapegoating and pass the buck posturing. Not that many choices will be available then to deal with the problem. Even if by some magic we could stop current entropy maximizing economic activity, we have already dug a hole deep enough to screw us over in the coming centuries. But we will keep on digging until it is well beyond too late.

The economy is a combustion process. Regardless of the political system. I doubt some solution will be found to have the sustainable system that people are calling for. Humans only had something like it when they were just another animal species surviving with very primitive tools. Looks like that is what some survivors of modern civilization will be forced to go back to.

The ocean is the chief reservoir of heat on Earth just as the polar ice is the chief reservoir of cold on Earth.

La Nina is here, threatening even bigger blazes and storms

Yes, it's been soaking up 90 some percent of the heat from gw, and about a quarter of the CO2.

We will eventually, one way or the other, stop dumping vast extra quantities of waste CO2 into the atmosphere, iirc.

And if (very big if indeed) other CO2/methane feedbacks haven't powerfully kicked in by then, and atmospheric CO2 and heat begins to stabilize, the ocean will become a source of both heat and CO2, extending our global warming forcings far far into the future after we are (likely) long gone

“With global warming, marine heatwaves like 'The Blob' could be commonplace”

“Sept. 24 (UPI) -- In 2015, a marine heatwave dubbed "The Blob" expanded across the Northern Pacific. At its peak, the mass of warm water extended more than 2,000 miles in length, measured 1,000 miles wide and extended several hundred feet beneath the ocean surface. According to a new study, anthropogenic climate change has made extreme heatwaves like the Blob more likely. In fact, the study's authors claim human-caused global warming is directly to blame for the Blob. The Blob would not have occurred in a world without climate change," lead study author Charlotte Laufkötter, a marine scientist at the University of Bern in Switzerland, told UPI in an email. The Blob was the largest and longest heatwave in the last half-century, covering a few million square miles of ocean and lasting more than 350 days.”
