So in fresh smoke the ozone gets titrated out by all the VOCs but its more complicated as the smoke moves and ages- this paper is a great look into the chemistry! www.science.org/doi/full/10....

Celebrating Richard Flagan's 50 years of service to @caltech.edu! Rick arrived in 1975 intending to study combustion chemistry and ended up playing an enormously influential role in developing new instrumentation to quantify atmospheric aerosol and helping to mitigate air pollution in LA and beyond.

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

Indeed. Remarkable how quickly batteries went from irrelevant to a major component of the California grid. Has also enabled renewed growth in solar which had tapped out at ~100% of noontime supply.

I wrote about how Calcarea's Pierre Forin is working on a way of trapping the greenhouse emissions that giant shipping vessels produce as they crisscross our oceans.

David Baltimore, Nobel-Winning Molecular Biologist, was president of @caltech when I joined the faculty. Inspirational leader and remarkably impactful scientist who was also kind. May his memory be a blessing www.nytimes.com/2025/09/07/s...

⭐️⭐️⭐️⭐️⭐️ “Earthquake Insights” by @judithgeology.bsky.social and Dr. Kyle Bradley is consistently well-written, well-researched, and accessible to everyone from experts to the scientifically interested public (no small feat)! Worth subscribing.

Out as preprint, we have some very interesting results looking at the radiative forcing impacts of the 2022 Hunga eruption. Based on the outcomes of the related OMIP, with many models from all over the world participating in this effort, we find a robust cooling signal from the Hunga volcanic plume.

Simply spectacular imagery of Hurricane Kiko's stunning eye.

I will probably never have an experience like this again in my lifetime, so I will always treasure my summer with this family of burrowing owls. 💕🪶

Hey @vfmcneill.bsky.social! Look at the BlueSky message from Science about the paper!

NEW: The first evidence of a solar take-off in Africa☀️✈️ x33 rise in Algeria solar panel imports in the 12 mths to June 2025, compared to previous 12 mths. x8 in Zambia x7 in Botswana x6 in Sudan x3 in each of Liberia, DRC, Benin, Angola, Ethiopia 🧵

Solar panel imports will reduce OVERALL imports - because the value of diesel imports eclipses the value of solar panel impors. A solar panel in Nigeria now costs just $60, and can repay the cost of diesel for a generator within 6 months - and even less in other countries.
