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...

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 10 th 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.

There is a 50-60% chance of an El Niño event forming in middle to late 2017, according to a new Update from the World Meteorological Organization. The El Niño/Southern Oscillation (ENSO) is a naturally occurring phenomenon involving fluctuating ocean temperatures in the central and eastern equatorial Pacific, coupled with changes in the atmosphere. It has a major influence on weather patterns in many parts of the world and has a warming impact on global air temperatures.

Recognizing that Africa is particularly vulnerable to the impacts of climate change, the World Meteorological Organization has launched the Training Programme on Climate Change Adaptation and Disaster Risk Reduction in Agriculture t o improve the capacity of national technical services in West African countries. The programme seeks to reduce the impacts of natural disasters and climate change on the agricultural sector and to support sustainable development. “Climate change is threatening food security in many parts of the world,” said WMO Secretary-General Petteri Taalas. “This new training...

Heavy rainfall has caused devastating flood and landslides in Colombia and Peru, with heavy casualties, damage to property and infrastructure and economic disruption. The landslides that began in the early morning of April 1 in the Amazonian region of Colombia were caused by unusually intense rains and by the overflow of the Mocoa, Mulato and Sangoyaco rivers. The town of Mocoa has been almost completely buried, thousands of people have been affected in different municipalities and find themselves without drinking water or electricity, hundreds of homes have been destroyed and the Colombian...

A nightmare scenario for any community is to be taken by surprise in the middle of the night by a sudden disaster such as the mudslide that swept away hundreds of lives earlier this month in the Amazonian town of Mocoa in Putamayo, Colombia. Heavy rain over a three-hour period combined with deforestation and unstable soils to reveal once more that human decisions often interact with extreme weather events to create disasters.

Significant progress has been made over the past decade in improving understanding of droughts and their impacts. However, several questions remain, including the real costs to a country’s economy, and whether the price of preparing for droughts is worth it. A new study released by the World Meteorological Organization and Global Water Partnership seeks to answer these questions.

A new report from the Arctic Monitoring and Assessment Programme (AMAP) on Snow, Water, Ice and Permafrost in the Arctic highlights the rapid and widespread changes in the Arctic’s sensitive climate systems mostly due to rising concentrations of greenhouse gases. One of the key findings of the report by AMAP, which is one of the six working groups of the Arctic Council, is that “the Arctic’s climate is shifting to a new state.”

Normal rainfall is most likely during the 2017 Southwest monsoon season (June – September) over much of South Asia, according to the South Asian Climate Outlook Forum held in Bhutan 24-26 April. The outlook was developed through an expert assessment of various observed and emerging climatic features that influence the monsoon, including the El Niño~Southern Oscillation (ENSO). The Southwest monsoon accounts for 70-80 percent of annual rainfall in most countries of South Asia. It is a key driver of socio-economic development and well-being in the world’s most densely-populated region which is...
