Earth's atmosphere more chemically reactive in cold climates

Earth's atmosphere more chemically reactive in cold climates 05/25/2017 07:03 PM EDT 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.
