There's another reason that the Bass campaign definitely wants to discredit this "outlier" poll. Crosstabs are out and "fixing streets, sidewalks, streetlights and other city infrastructure" is listed first across the board as the top priority for LA voters. Even above homelessness and crime!

Next up is a report from Office of Major Events on Kick It in the Park activations that drew 45,000 people to 100 watch parties. Hard to see that middle panel: 84% of surveyed attendees said they’d come back to their local park more often if the temporary shade structure was made permanent

Getting cars off the road and greening the streets is easily the most effective way to cool a city and an obvious outgrowth (pun) of traffic calming that's already underway. Instead of dithering on an urban forest “plan” Mamdani should make like Paris and get this done in a comprehensive way now

Urban heat island effects are bad enough. Clustering data centers in cities, each of which can produce the heat of 54,000 houses, will make it exponentially worse, especially in already hot places like Phoenix Gift link to this great @bloomberg.com infographic: www.bloomberg.com/graphics/202...

Since it’s always a scandal when politicians fabricate stories about their past, Trump making up where he was on 9/11 like this will definitely be a scandal, I’m sure — and a bigger headline than whether or not Mayor Mamdani will attend memorial services at ground zero on Friday. Right?

Terrific @lloydalter.bsky.social column today about 78°F * It’s a metric invented by the air conditioning industry as a limit of effectiveness for their machines * 78°F is not hot and is perfectly comfortable in light clothing * People can tolerate up to 95°F and still feel comfortable

No, 78°F is not communism. It's not even hot.
Those commies at ASHRAE set 78° at the high end of "comfortable." Now, a nation at war can't make the smallest sacrifice to reduce demand or help stabilize the grid.

This is why cities need old tenements and rusty awnings. Hard surfaces can reach extreme temperatures when exposed to the sun, while shaded hard surfaces stay dramatically cooler. This is the effect of sun and shade in one image. Hard surfaces absorb and radiate heat, while shade reduces it.
