UN Secretary-General Antonio Guterres says it is now clear that efforts to cap global warming at 1.5C above pre-industrial levels will fail in the short term. AFP: Before next month’s COP30 climate summit in Brazil, Guterres said going beyond 1.5C would result in “devastating” yet predictable impacts. “One thing is already clear: we will not be able to contain the global warming below 1.5C in the next few years,” Guterres said at the UN’s World Meteorological Organisation (WMO) weather and climate agency in Geneva.

“Overshooting is now inevitable. Which means that we’re going to have a period, bigger or smaller, with higher or lower intensity, above 1.5C in the years to come.” However, if leaders start taking the problem seriously by driving towards net zero greenhouse gas emissions, “the 1.5 still remains — according to all the scientists I met — possible before the end of the century.”
