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.

The studies are designed to minimize the effects of extraneous factors and focus on the relationship between the experimental exposure conditions and the biologic response being measured, for example, a temporary change in lung function. The goal is to observe temporary and reversible responses without causing clinical effects.

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The open access study is published in the journal Scientific Reports. —Can Li.

These were shown to be ozone-depleting, however, and were targeted for phasing out under the 1987 Montreal Protocol. However, HFC-134a, while having zero ozone-depletion potential, has a very high global warming potential—more than 1,500 times as much warming as an equivalent amount of CO 2.

Seven billion people, more than 95% of the world’s population, lived in areas exceeding the WHO Guideline for healthy air in 2016, according to a new global study. Ozone, another important component of outdoor air pollution, whose levels are on the rise around the world, contributed to 234,000 deaths from chronic lung disease.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below.
