The World Meteorological Organization Statement on the State of the Global Climate in 2018 (44 page pdf) was published today. Read informative press release HERE.

This publication marks the twenty-fifth anniversary of the WMO Statement on the State of the Global Climate, which was first issued in 1994. The 2019 edition treating data for 2018 marks sustained international efforts dedicated to reporting on, analysing and understanding the year-to-year variations and long-term trends of a changing climate.

The WMO climate statement includes input from national meteorological and hydrological services, an extensive community of scientific experts, and United Nations agencies. It details climate related risks and impacts on human health and welfare, migration and displacement, food security, the environment and ocean and land-based ecosystems. It also catalogues extreme weather around the world.

It complements the Intergovernmental Panel on Climate Change (IPCC) five-to-seven year reporting cycle in producing updated information for the United Nations Framework Convention for Climate Change and other climate-related policy frameworks.


Key findings of this Statement include the striking consecutive record warming recorded from 2015 through 2018, the continuous upward trend in the atmospheric
concentration of the major greenhouse gases, the increasing rate of sea-level rise and the loss of sea ice in both northern and southern polar regions.
