I live in a city that likes to call itself progressive, near an major arterial. There have been no significant changes to the way its traffic moves in 20 years. During the first couple months of Covid, with a lot of businesses shut down, there was a noticeable traffic reduction. But since mid-summer there's been as much traffic on Saturdays as there is on weekdays. And most of the newer cars are no smaller (every 10th one is quieter).

Short of putting Greening on a wartime-footing - massive incentives for change, including gas-rationing - I don't see the end of the tunnel-vision. The home-heating elephant in the room gets no press.

The earth’s climate will not become incompatible with human life in the next 500+ years in the worst case climate models. Where did you even get that idea?

Something tells me humans will let those 500 years pass without doing anything.
