New data released by the UN on Monday showing that greenhouse gases have surged to new highs clearly show once again that urgent action and not words is needed from the world's major polluting nations to protect us all from climate change, the World Meteorological Organization (WMO) insisted.
The appeal comes as global leaders prepare to gather for the UN's Climate Change Conference in Baku next month, amid repeated dire warnings about the human cost of ignoring the existential crisis from UN Secretary-General António Guterres .
Echoing the UN chief's longstanding appeals, WMO Deputy Secretary-General Ko Barrett told journalists that carbon dioxide (CO2) - one of the three main greenhouse gases, along with methane and nitrous oxide - is now accumulating in the atmosphere "faster than at any time experienced during human existence". Because of the extremely long lifetime of CO2 in the atmosphere, "we are committed to rising temperatures for many, many years to come," she added.
WMO's 2024 Greenhouse Gas Bulletin offers a stark, scientific reminder that rising CO2 levels need to be slowed. In 2004, the concentration of carbon dioxide in the atmosphere was 377.1 parts per million (ppm), while in 2023, this reached 420 ppm, according to WMO's Global Atmosphere Watch Network. "This is an increase of 42.9 parts per million, or 11.4 per cent in just 20 years," Ms. Barrett explained.
