For more than a decade, nations have strived to limit global warming to 1.5°C above pre-industrial levels — a threshold widely seen as critical to averting the worst impacts of climate change. That ambition is now impossible to achieve, according to the latest assessment from the United Nations.
The report finds the world is on track to cross 1.5°C in 2030. Current warming stands at about 1.4°C, and climate-boosted disasters — from historic droughts in the United Kingdom to wildfires in France and Spain, melting glaciers and record ocean temperatures — are already escalating.
Palau's President Surangel Whipps Jr. said in response: "It is hard to overstate the depth of emotion for those of us living on the frontline after having fought so hard to put the 1.5 degree limit at the heart of the Paris Agreement… calls for greater ambition are no longer enough — we need to see an urgent and unprecedented increase in political will and investment in a climate safe future."
The report offers a narrow path: if nations redouble efforts to phase out fossil fuels and reduce other emissions, peak warming could be capped at 1.8°C. Carbon removal methods could then gradually bring temperatures back to 1.5°C or below. The New York Times noted the UN has proposed a new framework focused on limiting the "overshoot" and eventually reversing temperature gains — a highly uncertain and unproven approach.
The emerging El Niño event in the Pacific is expected to cause further disruption and could push warming even higher in the near term. Every fraction of a degree, the report stresses, worsens the risks of irreversible damage.
