Atmospheric Carbon Dioxide Soars to 424PPM, Marking Biggest Yearly Jump Ever

The WMO reports Earth’s atmospheric CO₂ reached 422.8 ppm in 2024 — the biggest annual rise ever recorded. Driven by fossil-fuel emissions, wildfires, and weakening carbon sinks, the surge intensifies global warming. Scientists warn that delayed emission cuts could entrench irreversible changes in weather, ecosystems, and sea levels.
