New 📄! We inter-compare satellite-based NASA TEMPO column NO2 with ground monitor surface NO2. Correlation is very good; best in the mid-AM and worst in the late-PM. The work highlights when and where satellite data best represents surface air quality. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Found this somewhat positive news: Maryland & DC have 50% less CO2 emissions than 20 years ago (www.eia.gov/todayinenerg...) A portion of this decrease is because coal plants closed in-state and out-of-state coal plants took some of the load. Nonetheless, don't lose sight of the progress we've made!

Almost 2 years of TEMPO NO2 data now available. NO2 air pollution cannot hide!
While this NO2 map looks 🤩, NO2 pollution declines have stagnated over the past 10 years or so. The plot should be more blue by now...

You know what pisses me off the most? NASA's budget is a meager 0.48% of the annual federal budget. The "savings" of cutting its $23b budget in half is less than a penny on the dollar (~$0.0024/dollar). It's hardly a drop in the ocean, but the science and progress we'd lose would be immeasurable.
Cuts to #science of >50% at NASA and >75% at NOAA would end US climate and space science research.

A tricky thing about modern society is that no one has any idea when they don’t die.
Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.
