Slashdot reader [1]JustAnotherOldGuy shared [2]this report from the Guardian :
> Chronic ocean heating is fuelling a "staggering and deeply concerning" loss of marine life, [3]a study has found , with fish levels falling by 7.2% from as little as 0.1C of warming per decade. Researchers examined the year-to-year change of 33,000 populations in the northern hemisphere between 1993 and 2021, and isolated the effect of the decadal rate of seabed warming from short shifts such as marine heatwaves. They found the drop in biomass from chronic heating to be as high as 19.8% in a single year.

> "To put it simply, the faster the ocean floor warms, the faster we lose fish," said Shahar Chaikin, a marine ecologist at the National Museum of Natural Sciences in Spain and the study's lead author. "A 7.2% decline for every tenth of a degree per decade might sound small," he added. "But compounded over time, across entire ocean basins, it represents a staggering and deeply concerning loss of marine life."

I fear that we are not capable of taking action based on the results of scientific studies - even a scientific consensus. We are not convinced until it hits us directly, and even then we refuse to believe until it gets serious.
If this is true, then we'll take action when either:
(a) McDonalds takes the fillet o' fish off its menu, or
(b) we move into more enlightened political times
Someone have a presser about how this isn't true! (Score:2)

Someone needs to get their press secretary or some other trusted person in front of a microphone to say that this isn't true, and we don't have to do anything, and it would cost business too much to fix. Think of the poor stock market!
aerosole cooling (Score:1)
we need aerosole based sun ray reflection and thus cooling to be done immediately, this is way beyond CO2 content in the atmosphere, which we will not get rid of even if we stop producing any and all new CO2 right now. It will take thousands of years for the existing CO2 to be reduced and burried by natural processes. There won't be any natural processes if we don't cool down the planet asap.
