A chemical element so visually striking it was named for a goddess shows a "Goldilocks" level of reactivity—neither too much nor too little—that makes it a strong candidate as a carbon scrubbing tool.

Global CO2 emissions for 2022 reached 36.1 gigatons, and this consumed 13–36% of the remaining carbon budget to limit warming to 1.5°C, which means our permissible emissions could be depleted within two years.
Direct air capture may be key to saving Earth from the effects of climate change, but there's a catch: It's really hard to do.
