Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease. —Guy Brasseur.

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.,

JANUARY 23, 2020

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.
