A new World Meteorological Organization (WMO) public science lecture series starts on 8 May with a presentation from Thomas Stocker, Professor of Climate and Environmental Physics at the University of Bern and former Co-chair of Working Group I of the Intergovernmental Panel on Climate Change (IPCC). The presentation is entitled The Climate of Tomorrow: Building the Knowledge for Earth Stewardship

WMO’s Global Atmosphere Watch (GAW) Programme is marking its 30th anniversary this year. The programme, which embraces about 100 countries, aims at forging an integrated global understanding of atmospheric composition and change. It coordinates observations across local to global scales, driving high quality and high-impact science while co-producing society relevant products and services.

Recent developments in the climate change arena, including the Paris Agreement in 2015 and the publication of the IPCC Special Report on Global Warming of 1.5 °C, have noted the potential need for negative emission technologies to remove carbon dioxide from the atmosphere in order to limit temperature increase.

Increasing levels of airborne pollutants deposited either through gravity (i.e. free-falling) or washed out by rain can result in detrimental effects to crops, human health and vulnerable ecosystems by altering critical and delicate chemical balances. Identifying areas most at risk and which would most benefit from measures to control excessive pollutant load is crucial.

The full Scientific Assessment of Ozone Depletion is now available. It shows that actions taken under the Montreal Protocol have led to decreases in the atmospheric abundance of controlled ozone-depleting substances (ODSs) and the start of the recovery of stratospheric ozone.

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....

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.
