Early in the afternoon of Dec. 30, 2021, the Marshall Fire erupted in the grasslands outside two Denver suburbs. High-speed winds sent the blaze ripping through neighborhoods. Firefighters could ...

Low atmospheric carbon dioxide concentrations during glacial periods must have been accompanied by changes in surface-ocean carbonate chemistry. But it is unclear whether concurrent changes in the ...

The results showed that the hydrogen would deplete a chemical species that atmospheric chemists call the "detergent of the atmosphere," explains Candice Chen, a Ph.D. candidate in MIT's Department ...
