Right now millions on the East Coast are getting a preview of what breathing bad air feels like. A new study looks at who breathes it by design. Net-zero pathways with more carbon removal leave ~30,000 more Americans dying from PM2.5 in 2050, concentrated in lower-income places.

Rangelands including prairies & savannas support 500 million people worldwide, feeding herds of sheep, goats, and other animals. New research could help agribusinesses and countries choose grazing practices on these lands that will cut emissions targets and move them closer to their climate goals.

Less grazing, more feed for livestock in some regions may benefit climate
Altering livestock grazing could allow soils to store billions more tons of carbon each year, depending on the region. But net climate benefits depend heavily on where supplemental feed comes from.

The Global Carbon Project has just published the most comprehensive Global Hydrogen Budget to date. H2, although not a GHG, has an indirect Global Warming Potential 37 times more potent than CO2. Carbon Brief: www.carbonbrief.org/hydrogen-emi... Research paper: www.nature.com/articles/s41...

Hydrogen emissions are ‘supercharging’ the warming impact of methane - Carbon Brief
The warming impact of hydrogen has been “overlooked” in projections of climate change, authors of the latest “global hydrogen budget” say.

An update of the Global Hydrogen Budget. The biggest source of H2 into the atmosphere is oxidation of CH4 and NMVOCs. So if you care about the climate effects of H2, reduce your CH4 emissions... www.nature.com/articles/s41... 1/

@science.org confirms that yesterday the Trump admin wiped out the technical staff of the U.S. National Climate Assessment and the Global Change Research Program. When USGCRP's acting director, who is on a time-limited contract, leaves, it will leave the congressionally mandated office empty.

Replacing conventional building materials with materials modified to store carbon dioxide could move the planet closer to net-zero greenhouse gas emissions, according to a new study in Science.
scim.ag
Building materials could store more than 16 billion tonnes of CO2 annually
Achieving net-zero greenhouse gas emissions likely entails not only lowering emissions but also deploying carbon dioxide (CO2) removal technologies. We explored the annual potential to store CO2 in building materials. We found that fully replacing ...

Our analysis out today in @science.org and led by Elisabeth Van Roijen (of NREL and formerly @ucdavis.bsky.social) shows that building materials--and especially concrete--are an enormous potential reservoir to store carbon (we think >16 Gt CO2 / yr). www.science.org/doi/10.1126/...
