🦋 In 20 years, the contiguous U.S. lost 22 percent of its butterflies, according to a groundbreaking new study published today.
We got the data, and I made a tool that lets you find out what's happening with butterfly species in your town.

"In America, the lack of government support is one reason so many fusion researchers are joining start-ups, Dr. Liu said.
Chinese officials, by contrast, are putting significant resources into a possible “ultimate solution” to humankind’s energy needs"

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.

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.

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.

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.
