this is one of several "failure modes" connected to climate change that are bieng dissmissed out of hand and in spite of all the blither blather about humans determining our own future as seperate from anything as trivial as the "weather", we exist as the prime exploiter of what can be summed up as the carbohydrate production of nature, a single number of X millions of tons per anum, which our breathable atmosphere, is a byproduct of.
OgsyedIE•3h ago
There is no candidate for the prime exploiter of NPP at this time, since any numeric measure of chemical throughput has us almost tied with marine protists.

Furthermore, the majority of calories consumed by humans are derived from the Haber-Bosch process, which entails exploiting ancient reserves of stored sunlight instead of the present-day supply of sunlight.

(2010) should be in the title, presumably?

> "Today, there are not enough organics in the oceans to go anoxic," says Kump. "But in the Permian,"

The editorialized HN title misrepresents what the article says.

DrierCycle•1h ago
Have you talked with an oceans specialist recently? Anoxic events are difficult to predict. Not all specialists agree with that Permian isolation.

That's interesting, but the title still misrepresents the article. Flagged.

As the issue now includes a deepening of recent radical shift potential in equator-to-pole gradient, the chances for this are now measurably distinct.

The question is left open, particularly in the recent data on gulfstream collapse, which may be imminent.

I'm not sure anyone is qualified to claim 100% anoxic events are limited to the Permian condition.

and

are in conflict.

My main concern is the acidification of the ocean due to the carbon dioxide equilibrium between the atmosphere and the sea. There is a threshold level threshold at wich the shell of plankton just dissolves. After that happens I think the whole ocean ecosystem will collapse (maybe no more fishes?) Also the deep ocean has an inertia of thousands years meaning that we are going to stick with industrial coal revolution levels of co2 in the atmosphere for a lot of time even if we emit nothing.

People wasn't seeing immediate effects because it was hidden in saturating the ocean and now there's no way back in my opinion
