Scientists find a human “fingerprint” in the upper troposphere’s increasing ozone

Knowing where to look for this signal will help researchers identify specific sources of the potent greenhouse gas

09-Aug-2024 - Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun’s harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant that can trigger chronic health problems ...
