As far as anyone can tell, China, the United States, India, Russia, and Japan (the five biggest polluters, in order) have not, and are unlikely to, agree on anything to permanently reverse climate change.
Since there is no negotiated agreement what is everyoneâs best alternative?
In each country there are corporate interests and the game of politics, payoffs. and tradeoffs. Â Thatâs the big one. *Can skip to my summary at the end if wanting to avoid the next essay. Â Phoenix AZ is putting in its second light rail and other US cities are expanding theirs (Houston TX and I read maybe Atlanta, GA?). On the other side, many public transit options are increasingly less appealing despite some promotion (Los Angeles and even the Dallas TX area) due to lack of enforcement. The second biggest US city, Los Angeles, has ever more drivers than mass transit takers since before COVID. Â Why? Â Actually neighborhoods adapted. Â Many find it quicker to just drive to, say, a grocery store. Â So think the focus as some âclean upâ starts will be poorer workers and tourist safety for the Olympics (of course when Rams games are on, the trains are packed with fans and their rapidly emptying beverage coolers .. hey, gotta roll with the flow).
However now the next best is the 15-minute city, town, and /or neighborhood. Â Based more on Paris than Los Angeles, the idea is residents have everything needed during the week within a 15 minute walk/bike ride. Â May be easier said than done on existing infrastructure but who knows .. especially as big boxes close down leaving a hole in communities (note: communities were warned). Â It makes sense and consumers still have the option to drive. Â They can just drive less if they want to.
Of course the same pro-pollution/pro-sprawl interests are fighting this, .. but itâs fairly easy to implement with a relaxation of local zoning laws.
Still with more concentration, that leaves more geographic area available for wildlife, ecosystem services (like wetlands and forests that can absorb flooding waters), and of course recreation – though honestly think much will go to mountain biking and other more âurbanyâ outdoor activities. Â Like the new mountain bike routes NW of Portland OR (membership required as itâs on timber company land and they donât want lawsuits).
Summary: think building vertically for a number of reasons for most folk, especially singles, will be the best we can do.
