The World Meteorological Organization (WMO) has reported that planet-heating pollutants in the atmosphere have reached record levels in 2023. Carbon dioxide concentration has increased by over 10% in just two decades, with concentrations reaching 420 parts per million. The WMO warns that this surge is driven by humanity's "stubbornly high" burning of fossil fuels and could lead to climate feedbacks like stronger wildfires and hotter oceans.
