Incidentally, the score for aluminum smelters built since 1990 would be ~50-60 for China, 0 for the US. www.nytimes.com/interactive/...

- 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. www.nytimes.com/2025/08/08/c...
- Reposted by Harry StevensBased 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.

- Reposted by Harry StevensSince the IRA passed, companies have made plans to invest over $843 billion in clean energy projects. But just one-third of that has actually been invested, new data shows.

- Reposted by Harry StevensRebecca Dzombak, Max Bearak & @harrystevens.bsky.social look at the possible long-term consequences from seabed mining. “Part of the challenge in understanding potential effects is that the pace of life is slow on the seafloor. Deep-sea fish can live hundreds of years. Corals can live thousands.”
- 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. As seen in www.nytimes.com/2025/04/25/c...
- A cylindrical or pseudocylindrical (in this case Patterson's Natural Earth) projection will start looking real scrunchy at around 600 pixels, but the stacked Lamberts work great down to 300 pixels — as narrow as you'll ever need.
- I first saw this last year in a map by @bananafish.bsky.social. Not sure if he invented it or saw it somewhere else. www.washingtonpost.com/climate-envi...
- The azimuthal equal-area projects the sphere onto a disk and preserves area across the projection. You can display the whole planet, but latitudes far from the center get very distorted. The clipped two-hemisphere approach avoids the distortion and fits nicely on a phone.

- 🦋 The study didn't investigate causes, but habitat disruption and pesticides likely contributed to declines. Climate change may have played a role: species saw larger drops in the south of their ranges, suggesting northward migration w/ temp. increase. www.nytimes.com/interactive/... 3/3

- At this rate we'll bend the aerosol cooling curve back up to 0 long before we bend the greenhouse warming curve back down.

- Most Americans say they prefer a bigger house in the suburbs vs. a smaller place in a walkable neighborhood. Yet sprawl is objectively bad in many ways, and there is an undersupply of walkable neighborhoods relative to demand. More analysis and walkability data in Climate Lab: wapo.st/41lOtkO
- Many U.S. cities were built for cars. Zoomed out, car-oriented cities all look about the same on the map: dense downtowns surrounded by sprawl with arterial highways dissecting areas where walkable neighborhoods might otherwise be built. Gift link for more: wapo.st/41lOtkO
