Extreme weather and climate events
Weather and climate extremes have been recorded across the world since January 2007. It is likely that global land surface temperatures in January and April were the warmest since records began in 1880 by +1.89°C and +1.37°C, respectively. Several regions have experienced extremely heavy precipitation, leading to severe floods.
The Fourth Assessment Report of the WMO/UNEP Intergovernmental Panel on Climate Change (IPCC) notes an increasing trend in extreme events observed during the last 50 years. Furthermore, according to the IPCC it is “very likely” that hot extremes, heat waves and heavy precipitation events will continue to become more frequent.
WMO and the National Meteorological and Hydrological Services of its 188 Members are working with other UN agencies and partners towards the establishment of a multi-hazard early warning system. They are also putting in place sustainable observation systems which are needed for monitoring and assessing the impacts of climate change and determining the adaptation priorities for the most vulnerable countries.
