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. This would have been a big win for climate. —co-author Dr Matt Rigby.

Scientists from the US, Norway, Russia, Germany, Italy and China are participating in a study examining the potential role of black carbon, or soot, on the rapidly changing Arctic climate. The Arctic climate is changing faster than some scientists expected. Black carbon is contributing to this warming.

Freight transportation is a pillar of the US national economy, but while long-haul trucks account for less than 6% of the vehicle miles traveled over US highways, they account for about 40% of the emissions of air polluting particulate matter and about 55% of nitrogen oxides, the precursor to ozone in the atmosphere, the study said.
