Bulletin nº Vol 69 (1) - 2020
Publish Date: 23 March 2020
The Earth’s atmosphere's main cleansing mechanism removes chemicals from the air and deposits them onto land and water surfaces. While the effects of these removal processes are mostly beneficial, some can have negative impacts on human health, ecosystems and food security. For example, acid rain – the acidification of rainwater due to nitrogen and sulfur emissions – damages forests, kills insects, corrodes industrial metal structures, etc. Such adverse impacts of deposition are of great interest to society as a whole and more particularly to policymakers, thus, WMO decided to undertake the...

Twelve international organizations providing assistance to developing countries came together at the UN Climate Change Conference today to launch the Alliance for Hydromet Development. The members of the Alliance have committed collectively to ramp up action that strengthens the capacity of developing countries to deliver high-quality weather forecasts, early warning systems, water, hydrological and climate services. Known for short as “hydromet” services, these underpin resilient development by protecting lives, property and livelihoods.
Small Island Developing States and Member Island Territories are low-lying island nations that are highly vulnerable and often affected by weather extremes and climate change, including the increased severity of cyclones, storm surges, heavy rains, droughts, sea-level rise and ocean acidification. Investments in disaster risk reduction, including early warning systems and adaptation measures for critical sectors, are essential for building resilient communities and facilitating sustainable development.
Start date1 June 2013
Assisting in the capacity development of National Meteorological and Hydrological Services (NMHSs) by improving human, technical and institutional capacities and infrastructure, particularly in developing, least developed and small island developing states and territories in order to enable them to deliver weather, climate and water-related services.
Start date27 January 2016
South-East Europe has experienced a significant number of severe meteorological and hydrological events in recent years. Heavy precipitation has caused floods and landslides. Droughts have increased the incidence of forest...

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.
