A strong El Niño event during 2019 appears unlikely, according to a new World Meteorological Organization Update, which is based on forecast models and expert opinion from around the globe. Sea surface temperatures in the tropical Pacific Ocean have been at borderline to weak El Niño levels in April and early May 2019. Some El Niño-like atmospheric patterns have also been present.

Climate change, population increase, urbanization and environmental degradation are amplifying the impact of extreme weather, water and climate events such as tropical cyclones, floods and extreme heat on growing numbers of people. Improved early warning systems and more coordinated disaster risk reduction are more important than ever before.

The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures towards increasingly dangerous levels, according to a new report from the World Meteorological Organization. The WMO Statement on the State of the Global Climate in 2018, its 25 th anniversary edition, highlights record sea level rise, as well as exceptionally high land and ocean temperatures over the past four years. This warming trend has lasted since the start of this century and is expected to continue.

There is a 50-60% chance of El Niño developing by May 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures in the tropical Pacific were at or slightly below El Niño thresholds in January and early February 2019. Some El Niño-like atmospheric patterns also emerged around late January.

There is a 75-80% chance of an El Niño developing by February 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures are already at weak El Niño levels in part of the tropical Pacific, although the corresponding atmospheric patterns have not yet materialized.

The powerful 2015-2016 El Niño has passed its peak but remains strong and will continue to influence the global climate, according to the latest update from the World Meteorological Organization. It is expected to weaken in the coming months and fade away during the second quarter of 2016. Eastern and central tropical Pacific Ocean surface temperatures were more than 2 degrees Celsius above average in late 2015, providing evidence that the 2015-16 El Niño is one of the strongest on record, comparable with the 1997-98 and 1982-83 events. It is too early to establish conclusively whether it was...

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...
