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.

High quality data underpins scientists’ growing understanding of our climate. The World Meteorological Organization has therefore created a WMO Catalogue for Climate Data as a trustworthy source of internationally recognized datasets. It has also reinforced its support for historical weather stations which contain records which are vital for monitoring long-term climate change.

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.

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.
