Earth's atmosphere more chemically reactive in cold climates
A Greenland ice core providing a first glimpse at the history of
reactive oxidants shows that for big temperature swings in the past
100,000 years, reactive oxidants are actually higher in cold climates.
This means that new mechanisms -- not just water vapor, plant and soil
emissions -- must affect the concentration of ozone and other oxidants
in the atmosphere.
