CSIRO study finds ozone uptake in oceans much lower than previously thought

Green Car Congress

JULY 31, 2019

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,

Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem.
