Average rate of warming per decade makes for easy mental arithmetic. Accelaration by tipping points suggest it is still rising, so for future projections I use 0.4 C. I also derive roughly that from a linear regression on past ~11years on gisstemp-v4. Global diesel fuel supply looks likely to decline permanently from about now, and industrial systems will collapse quickly wellbefore 2050, regardless of climate, without a full green transition , which is a kind of marketing canpaign to cover the end of overconsuming developed nations. This is so Good as only industrial collapse below net-zero can mitigate a runaway heating, even as all want to prevent economic collapse. Population collapse likely to be at least below 5% from current gross overshoot, if humans get lucky.
