Centuries of impacts seen from greenhouse emissions
The UN World Meteorological Organization (WMO) warned that atmospheric levels of carbon dioxide (CO2) and other greenhouse gases reached record highs in 2025—another portent of global warming, which increases the frequency of extreme weather events and associated risks to societies and economies. WMO deputy secretary-general Ko Barrett stated: “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.” (Photo: Janak Bhatta via Wikimedia Commons)
