More from the Arch bedwetter. About coral bleaching, whether it can recover from mass bleachings and then a curious graphic. Conflating SST increase with marine heatwaves, two entirely different things.
I will even resize it for him.

And then of course notice the 'y' axis, in zettajoules to scare the
unwary muppets.
And why?
The graphic talks about Ocean Heat Content, not even surface temperature or close to, where corals live.
It takes about 2600 Zj to raise the top TWO km of ocean by 1ºC, so that would make 300Zjor about 0.115ºC. Scary huh?

And then of course we know that they didn't have global coverage before Argo, about year 2000, so the knowledge in 1960 was rather less. And even now with 4000 Argo floats, the data points are still scarce.
Just colour me shocked that a person who claims to be a scientist doesn't know that.
Of course AIMS has their scary prediction attached to the 23-24 report after saying how good '24 was.

degrees Celsius, ocean heat content can be measured as energy, in gigajoules (GJ) or watts (W)."
https://climate.copernicus.eu/esotc/2023/ocean-heat-contentEdit 2: "he temperatures in the Argo profiles are accurate to ± 0.002°C and pressures are accurate to ± 2.4dbar."
