If school enrollment keeps declining and local income remains anemic, school closures and teacher layoffs in California could soon be inevitable. Building more infill is the only way to avoid this.

Climate targets can be useful tools, but they ultimately represent targets rather than thresholds. Every tenth of a degree warming is associated with more severe climate impacts, but there is no global climate tipping point.

Weakening growth in demand for oil and gas is already having geopolitical consequences. When oil goes ex-growth, all hell will break loose - and all heaven too. Expect some highly non-linear decades.

I finally read the op ed. Matt Yglesias is right. (98% right at least, which is an A+ for a NYT op ed). Don't @ me. It's the holidays and I don't have the appetite. But Matty's position is pragmatic, substantively sound, and the only way we have a chance of making progress on climate in this moment.

The Father Coughlin story is interesting because of parallels to the modern era. Wildly popular charismatic figure (30M listeners at peak when US had ~120M ppl). Private broadcasters tried to fact-check, pre-clear speeches, ban him while fans protested the censorship. FDR tried to stay out of it.
There’s no daylight between what Candace says here about “the Jews” & what Nazi propagandists & Father Coughlin said about the Jews in the 1930s. Her show is one of the top 5 “conservative” podcasts in the US. She has 5.5 million subscribers on YouTube and 7.3 million followers on X.

I always learn from Jenny’s annual discussion of solar. She leaves out the most important point IMHO: $0.09/w panels at TW/year are a global prosperity engine if used to produce goods and services. It’s worth taking a minute to wrap your head around this unprecedented abundance. 🧵
13. By 2030 most countries will have spot power prices of zero in sunny hours. This will be passed on to end consumers, to encourage them to shift power demand to sunny periods by electric vehicle and battery charging, preheating, precooling, etc.

I would also note that nobody really knows, when they install a residential solar and battery system, what the economics are going to be. In the days of feed-in tariffs you had a good idea, but nowadays it really does depend on future power price structures.

Both solar and lithium batteries are on exponential growth curves of about 30%, but most of the batteries are going into cars, with reduced availability for charging at solar peak. We need new ways to soak up TWh of solar, such as synfuels or thermal storage, ASAP.
Fascinating! I foresee that battery storage will strongly increase (which combined with strong battery price decreases means ~100x more batteries in the coming 10 years) and this will support solar+wind and reduce grid investments.
