Today on Volts: for years, I've wanted to do a podcast on indoor air quality, and I finally found the perfect guest! Dr. Lagoudas & I discuss indoor air pollutants, the policies and technologies that can control them, and the growing need to frame indoor air quality as a basic human right.

Now that the Sept and Oct data are (belatedly) in, it looks like 2025 will be the second warmest year in the record (~80% probability). The last three years are in a class of their own.

Congratulations to John Mak and all of GOTHAAM. The NSF-NCAR video summary really captures the magic of atmospheric chemistry

We have a new PhD project to study ozone formation from fires. If interested in atmospheric chemistry, fires, living in Zurich, and studying at ETH, consider applying here: jobs.ethz.ch/job/view/JOP...

LA is building a new $1.5 billion freeway into LAX. The very same airport where we just spent $2 billion on the people mover — actually, more like $3 billion, plus another $900 million if you count Metro's investment in the LAX station; so let's just say $4 billion — to make cars go away

When and how will quantum computing broadly benefit humanity? Despite exhilarating recent progress, we still don’t know. Here my friend Jens Eisert and I assess the current status and the challenges ahead. arxiv.org/abs/2510.19928

5. Solar modules now cost 8.9 US cents per Watt (higher in US, India due to trade barriers). Solar panels are cheaper than ordinary fencing materials. For rooftop installs, non-module cost is still $0.50-3.00 per Watt, so further module price declines make little difference.

Was wondering where the first game of the world series will be so I asked google whether BJs or Dodgers have a better regular season record which is determinative: AI Overview The Dodgers have a better regular season record than the Blue Jays with a record of 93-69 compared to the Blue Jays' 94-68.

Caltech researchers have now developed technology to freeze and preserve stem cells from birds that can then be reconstituted to help propagate populations. www.caltech.edu/about/news/s...

Deep dive into the surge in US pedestrian deaths: "It’s not that more pedestrians are getting hit by vehicles; it’s that the ones that are getting hit are more likely to die." "[That] seems like fairly strong evidence for the theory that the rise in large SUVs is behind the uptick in ped deaths."

Sometimes science is field work, sometimes it is lab work, computer work, discussions, presentations... and sometimes it is executing plan B and driving a highly sensitive and sophisticated scientific instrument across four countries and over 1500 kilometers! www.ionicon.com/blog/2025/a-...

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....

Congratulations @chriskenseth.bsky.social !

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. 💕🪶

Just watched the powerful new PBS documentary “Clearing the Air: the War on Smog”. My colleague Ellie Browne acted as Science Advisor. Very proud of her! www.pbs.org/wgbh/america...
