Record greenhouse gas concentrations mean further warming The tell-tale signs and impacts of climate change – such as sea level rise, ice loss and extreme weather – increased during 2015-2019, which is set to be the warmest five-year period on record, according to the World Meteorological Organization (WMO). Greenhouse gas concentrations in the atmosphere have also increased to record levels, locking in the warming trend for generations to come.

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.

Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization (WMO). There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather.

Geneva 12 April 2017 (WMO) - The World Meteorological Organization has issued its first annual Airborne Dust Bulletin, giving an overview of atmospheric dust levels and geographical distribution in 2016. The report is part of efforts to improve observations and warnings of sand and dust storms, which pose serious risks to the environment, human health and economy in arid and semi-Arid regions. The global average Aerosol Optical Depth – a measure of the dust burden - for 2016 was similar to previous years, according to the report, which highlighted particularly severe sand and dust storms in...
