The sun is shining, the birds are singing, the air quality meter is red due to wildfire smoke and alerting me that the air outside is dangerous to breathe, the people are choosing to breathe in wildfire smoke instead of masking because others might think they look weird, the grass is growing, etc.

To drive the point home, ICE is not/not the military—despite all the absurd operator cosplay. ICE agents are not going to be prosecuted for desertion if they simply walk away. There is no ICE UCMJ.

The event over #Kazachstan at ~17 UTC today was NOT a Russian #missile, but likely the Chinese Zhuque-2E upper stage (2025-103G) which was expected to reenter today. It did pass over Kazachstan around 17:10 UTC which would be ~10 pm local time.

Confirmed: the May average of atmospheric CO2 at Mauna Loa was 430.5 ppm, first time above 430 ppm in 15 million years, and a big jump from a year ago, again: +3.6 ppm! Overall, we're still speeding in the wrong direction.
