The United Nations’ World Meteorological Organization (WMO) has validated alarming data revealing that 2023 marked the hottest year ever recorded, cementing the close of the hottest decade on record. The WMO’s annual State of the Climate report, released on Tuesday, underscores the gravity of the situation as heatwaves ravage oceans and glaciers face unprecedented ice loss.
UN Secretary-General Antonio Guterres characterized the report as a distress call from Earth, emphasizing the urgent need for action to combat climate chaos fueled by fossil fuel pollution. The average near-surface temperature in 2023 soared to 1.45 degrees Celsius above pre-industrial levels, perilously close to the critical 1.5-degree threshold outlined in the 2015 Paris climate accords.
“The average near-surface temperature in 2023 was dangerously close to the critical 1.5-degree Celsius threshold outlined in the Paris climate accords.”

WMO Chief Andrea Celeste Saulo issued a stark warning, describing the report as a “red alert to the world.” The organization revealed that numerous records were not only broken but also “smashed,” highlighting the alarming acceleration of climate change.
Beyond rising temperatures, the report underscores other concerning phenomena, including unprecedented ocean warmth, glacier retreat, and Antarctic sea ice loss. Marine heatwaves afflicted nearly a third of the global ocean on average throughout the year, with over 90% experiencing heatwave conditions at some point. These developments pose severe threats to marine ecosystems and coral reefs.
Furthermore, key glaciers worldwide witnessed their largest ice loss since records began in 1950, with alarming declines observed in regions like Western North America and Europe. Antarctic sea ice extent hit a record low, exacerbating rising sea levels.
The report also sheds light on the humanitarian toll of climate change, with extreme weather events exacerbating food insecurity and displacement. Despite these grim findings, the WMO points to a glimmer of hope in the surge of renewable energy generation, which increased by nearly 50% in 2023.
Secretary-General Guterres remains cautiously optimistic, emphasizing that there is still an opportunity to limit long-term temperature rise and mitigate the worst impacts of climate change. However, urgent and decisive action is imperative to safeguard the future of our planet.
