ABOUT WMO

he annually published WMO Statements on the status of the World Climate provides details of global, regional and national temperatures and extreme weather events. It also provides information on long-term climate change indicators including atmospheric concentrations of greenhouse gases, sea level rise, and sea ice extent. The year 2016 was the hottest year on record, with many weather and climate extremes, according to the most recent WMO report.

World Meteorological Day-

The World Meteorological Day is held annually on 23 March.
