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.

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.
