Human activity has increased the direct warming effect of carbon dioxide (CO₂) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index . In 2015, the global average CO₂ concentration reached 399 parts per million, increasing by a record amount of almost 3 ppm. From the end of the Ice Age to the beginning of the industrial era, atmospheric carbon dioxide remained remarkably stable at 278 ppm.

Recognizing that expanded and improved observations now make possible a broader assessment of global atmospheric chemistry, the WMO Global Atmosphere Watch programme has published a new report on global and regional trends in reactive gases. This group of gases includes such chemicals as surface ozone, nitrogen oxides, carbon monoxide, sulfur dioxide, and volatile organic compounds, many of which are considered to be harmful pollutants. The first issue of the Reactive Gases Bulletin reviews long-term observation data on volatile organic compounds (VOCs) and discusses past and recent trends....

The science community is concerned: many established researchers plan to retire in the coming decade and there is a dearth of early and mid-career researchers ready to take their place and contribute in a meaningful way. Unless young scientists are encouraged, trained and mentored in various scientific fields knowledge gaps will occur.

Since the year 2000, both average and peak surface ozone concentrations have levelled off and even started to fall at some locations after increasing throughout the twentieth century, according to a new report from the World Meteorological Organization.
