Bulletin nº Vol 64 (1) - 2015
Theme: Environmental challenges

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.
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 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.

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...

Haiti’s National Meteorological and Hydrological Service (UHM) has a new headquarters – an important milestone in the drive to improve weather forecasts and warnings, and build resilience to tropical cyclones, floods and other hazards. The new building was inaugurated at a high-level ceremony on 26 May. It is constructed to withstand earthquakes and hurricanes, enabling operations to continue during extreme events when services are most needed. Solar panels will power daily activities and will provide a back-up against electricity outages.

African leaders are coming together this week for action on modernizing weather and climate services, which inextricably link the Continent’s development, climate, and resilience agendas. Weather and climate drive nine out of ten disasters in Africa, threatening Africa’s hard-won development gains. Floods, droughts, tropical cyclones, and landslides continue to cause heavy damage and losses to livelihoods. Over the last two decades, these disasters have cost the continent US$10 billion dollars. Given the increasing climate variability, these disasters are projected to increase in frequency...
