It's also worth note that this is mostly caused by the ban on sulfur emissions a couple of years ago. The commission that banned sulfur emissions from ships basically decided that they were going to do a big geo engineering experiment and they were going to do it not in favor of humanity against global warming, but in favor of global warming against humanity.

And they decided to cut off emissions really quickly so that we get this massive incredible hilariously bad spike instead of slowly tapering off over time.
