The World Meteorological Congress has made a groundbreaking decision to approve a newgreenhouse gas (GHG) monitoring initiative, according to the World Meteorological Organization (WMO). This initiative aims to support urgent action in reducing heat-trapping gases that contribute to rising global temperatures. The newly establishedGlobal Greenhouse GasWatch will address critical information gaps, integrating various observing systems, modeling capabilities, and data assimilation under one comprehensive framework. The unanimous support from WMOs 193 members highlights the growing importance of greenhouse gas monitoring and the need to strengthen the scientific foundation for climate change mitigation efforts.
