Even a change of 1 C in the average temperature results increases the probability of 5 C and higher days by hundreds of times

MacDougal, et al, strongly disagrees with this
"In all simulations atmospheric CO2 concentration declines after emissions cease, with a rapid decline in the first few decades followed by a slower decline thereafter"

![What amateurs lack as a group is perspective, an understanding of how everything fits together and a sense of proportion. Graduate training is designed to pass lore from advisors to students. You learn much about things that didn't work and therefore were never published [hey Prof. I have a great idea!...Well actually son, we did that back in 06 and wasted two years on it], whose papers to trust, and which to be suspicious of [Hey Prof. here's a great new paper!... Son, don't trust that clown.] In short the kind of local knowledge that allows one to cut through the published literature thicket.
But this lack makes amateurs prone to get caught in the traps that entangled the professionals' grandfathers, and it can be difficult to disabuse them of their discoveries. Especially problematical are those who want science to validate preconceived political notions, and those willing to believe they are Einstein and the professionals are fools. Put these two types together and you get a witches brew of ignorance and attitude.
Unfortuantely climate science is as sugar to flies for those types.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:6cq67q2ijx7oulnvqjg55htr/bafkreichasvjoytpwlaqd56opqavmncpakkak2wgjfkevmssxcrwmiq66q@jpeg)

Been saying for over a decade that Africa does not need telephone poles. Grid extension costs are the killer. Once you have to put up a long line to reach a small village small solar with batteries is the way to go in Africa
