Great @bradplumer.bsky.social @harrystevens.bsky.social piece on China's nuclear ambition. I'm biased but I think a good satellite comparison is worth 1000 words.
Incidentally, the score for aluminum smelters built since 1990 would be ~50-60 for China, 0 for the US.

The EPA said it will stop updating a database that companies use to calculate the greenhouse gas emissions from their supply chains. In July, EPA suspended the database's lead scientist because he signed a letter criticizing the Trump administration.

Based on fossil fuel growth rates from the IEA Coal Mid-Year Update, July Oil Market Report, & Gas Market Report Q3, fossil CO2 emissions would grow around 0.8% in 2025, reaching another record high...
We are only half way through the year, but don't build too much expectation for peak emissions.

A trick for fitting world maps on phones:
Stack two azimuthal equal-area projections, clipped at 90° longitude, each one rotated 180° from the other.
The bottom map covers the top's Antarctica, which reduces the total height and looks nice.
