New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean — one of Earth’s main cooling systems.
Ozone is a gas composed of three oxygen atoms. Many studies have described ozone in the stratosphere, and its role in shielding people from the sun’s harmful ultraviolet radiation. Closer to ground level, in the troposphere, ozone is harmful to humans.
New research led by UC Riverside scientists reveals this lower level ozone is adding a great deal of heat to the Southern Ocean — more than scientists previously understood.
This finding has now been published in the journal Nature Climate Change.
“People haven’t paid much attention in the past to tropospheric ozone in terms of ocean heat uptake. Based on our models, they should be,” said Wei Liu, UCR climate scientist and lead author of the new study.
