19 May 2017 - Climate change, associated extreme weather and demographic shifts means that record numbers of people are exposed to floods, heatwaves and other hazards. Improved early warning systems and more coordinated disaster risk reduction are therefore more important than ever before. To meet the growing challenges, an international conference will launch a concerted drive to improve warnings for an interlocking range of hazards and to translate these warnings into effective action on the ground.

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.

WMO report highlights impacts on human safety, well-being and environment 6 November 2017 (WMO) - It is very likely that 2017 will be one of the three hottest years on record, with many high-impact events including catastrophic hurricanes and floods, debilitating heatwaves and drought. Long-term indicators of climate change such as increasing carbon dioxide concentrations, sea level rise and ocean acidification continue unabated. Arctic sea ice coverage remains below average and previously stable Antarctic sea ice extent was at or near a record low.
