This article sounds like a press release for oil and ethanol producers. Big oil, still basically selling out the rest of humanity so they don’t lose all those profits.
I wonder what happens when the first countries go into wet bulbs. I can imagine state sponsored assassin teams avenging those afflicted societies by attacking every oil exec and their descendants. Or threatening hosting states with nuclear arms to dispose of them and redistribute the wealth to energy grid transition or else.. We humans tend to be very emotional towards the end.
This is part of the plot of Kim Stanley Robinson's "The Ministry for the Future". Worth a read.
