The latest climate science from WMO and the Intergovernmental Panel on Climate Change informed negotiations at COP25 in Madrid, Spain from 2 to 13 December 2019.
Ahead of COP25, WMO issued its Greenhouse Gas Bulletin, showing that levels of heat-trapping greenhouse gases in the atmosphere have reached yet another new record high. “The latest, just-released data from the World Meteorological Organization show that levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high. Global average levels of carbon dioxide reached 407.8 parts per million in 2018. Not long ago, 400 parts per million was seen as an unthinkable tipping point,” said UN Secretary-General Antonio Guterres.
An inaugural State of Climate Services in 2019 report was also released by the WMO-spearheaded Global Framework for Climate Services (GFCS).
The latest climate science results were also on display at the joint IPCC-WMO Science Pavilion at COP25. A number of side events were hosted at this pavilion throughout COP25, including an IG3IS side-event: WMO Tools for Climate Action.
The side-event showcased IG3IS as a set of innovative measurement-based tools that allow users and stakeholders to improve knowledge of national, sub-national and sectoral emissions, identify large and additional emission reduction opportunities, and provide decision makers with timely guidance on progress towards their emission reductions.
