All life depends on a healthy planet, but the interwoven systems of atmosphere, oceans, watercourses, land, ice cover and biosphere, which form the natural environment, are threatened by human activities. The Global Atmosphere Watch (GAW) programme provides reliable scientific data and information on aerosols, greenhouse gases, selected reactive gases, ozone, ultraviolet radiation and precipitation chemistry (or atmospheric deposition).

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.

In pitch dark at 40 below, a research expedition set out to the icy Arctic Ocean in January 2015.Their goal: to better understand ongoing changes in the Arctic due to a shift from an older and thicker ice cover that would survive the summer melt to a younger and thinner one that, to a larger degree, melts away in the summer.

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.

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...

A concerted international campaign to improve predictions of weather, climate and ice conditions in the Arctic and Antarctic has been launched to minimize the environmental risks and maximize the opportunities associated with rapid climate change in polar regions and to close the current gaps in polar forecasting capacity. The Year of Polar Prediction takes place from mid-2017 to mid-2019 in order to cover an entire year in both the Arctic and Antarctic and involves the World Meteorological Organization (WMO), Germany’s Alfred Wegener Institute (AWI) and a wide array of partners around the...
