• The World Meteorological Organization (WMO) has reported record-high concentrations of greenhouse gases in the atmosphere for
• Carbon dioxide levels reached 426.8 ppm, methane 1948 ppb, and nitrous oxide 339.1 ppb, marking significant increases from pre-industrial levels. The WMO bulletin highlights the role of these gases in trapping heat and driving extreme weather events. Additionally, the report warns of rising levels of molecular hydrogen and sulphur hexafluoride, which have potent warming effects. These findings come ahead of the COP31 climate conference in Turkey, where global climate strategies will be discussed. Source time: Tue, 27 Oct 2026 09:00:00 GMT.
Impact & Risks
The rising greenhouse gas concentrations are expected to exacerbate global warming, with the UN projecting a temperature increase of up to 2.8°C by the end of the century. This could lead to more frequent and severe weather events, impacting economies, societies, and ecosystems worldwide. Vulnerable regions, including India, may face heightened risks such as heatwaves, flooding, and agricultural disruptions.
