For more than 25 years, the annual State of the Global Climate Report, published by the World Meteorological Organization (WMO), has informed us on significant weather and climate trends. It provides authoritative evidence of global temperature increase, including sea-level rise, shrinking sea ice, glacier mass loss and extreme climate events. This week, the WMO presents key findings for 2019, a year that concludes the warmest decade on record. 2019 not only had high-impact weather, it also averaged 1.1 degrees Celsius above the pre-industrial period.
The year 2019 was the second warmest year on record after 2016, according to the World Meteorological Organization’s consolidated analysis of leading international datasets. Average temperatures for the five-year (2015-2019) and ten-year (2010-2019) periods were the highest on record. Since the 1980s each decade has been warmer than the previous one. This trend is expected to continue, because of record levels of heat-trapping greenhouse gases in the atmosphere. This confirms WMO's preliminary assessment that 2019 was one of the three warmest years on record.
Twelve international organizations providing assistance to developing countries came together at the UN Climate Change Conference 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.
