news.un.orgRecord carbon dioxide levels will impact us for centuries, says UN weather agencyThe agency’s latest Greenhouse Gas Bulletin indicates an average global concentration of CO2 at 426.8 parts per million (ppm) last year, or 153 per cent of the 1750 pre-industrial baseline. “Every additional part per million matters because it traps additional heat. In effect, we are supercharging the ocean and the atmosphere. That means that heat waves, tropical cyclones, and rainstorms are intensifying faster than our historical baselines prepared us for,” WMO Deputy Secretary-General Ko Barrett told journalists in Geneva. Equally worrying, levels of methane and nitrous oxide – the second and third most important long-lived greenhouse gases caused by human activities – also hit a new peak in 2025. “Another year, another new record. Greenhouse gases are trapping an unprecedented amount of heat in the atmosphere, providing energy for more extreme weather and associated risks to our economies and societies,” Ms. Barrett stressed. “The past 11 years have been the warmest on record and this trend is set to continue. CO2 has a very long lifetime and so will affect the global climate not just for years but for decades and even centuries.” When the Bulletin was first published in 2004, the annual average level of CO2 measured by WMO’s...
