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 Iran and China/Mongolia. It said there was no clearly-defined trend from 2003 through 2016, partly because of modelling capacity constraints and the relatively short time period since systematic observations began in 2003.

Top ozone experts from around the world highlighted the need for increased research and observations to inform policy on ozone and climate at a meeting sponsored by UN Environment and the World Meteorological Organization in Geneva, 28 – 30 March.

The 10th Ozone Research Managers (ORM) meeting concluded that integrated earth science observation systems are essential to ensure that action to protect the ozone layer also benefits the climate, given the complex and evolving interaction between the ozone layer and the climate system.

The World Meteorological Organization (WMO) Regional Association for North America, Central America and the Caribbean (RAIV) has held its four-yearly session with a focus on how to improve early warnings, disaster risk reduction and climate resilience.

Many countries in the region, which extends from Canada to the Caribbean, saw extreme or unusual weather including heatwaves and intense precipitation. Many are vulnerable to coastal inundation and storm surges, which are being exacerbated by climate change and associated sea level rise. There is increasing evidence that melting Arctic sea ice is affecting weather and ocean circulation in mid-latitudes

The World Meteorological Organization (WMO) has released its new, long-awaited, digitized International Cloud Atlas – the global reference for observing and identifying clouds, which are an essential part of weather, the climate system and the water cycle. It was released for World Meteorological Day on 23rd March.

The year 2016 made history, with a record global temperature, exceptionally low sea ice, and unabated sea level rise and ocean heat, according to the World Meteorological Organization (WMO). Extreme weather and climate conditions have continued into 2017.

WMO issued its annual statement on the State of the Global Climate ahead of World Meteorological Day on 23 March. It is based on multiple international datasets maintained independently by global climate analysis centres and information submitted by dozens of WMO Members National Meteorological and Hydrological Services and Research Institutes and is an authoritative source of reference. Because the social and economic impacts of climate change have become so important, WMO partnered with other United Nations organizations for the first time this year to include information on these impacts.
