March 20 (Reuters) – U.N. Secretary General Antonio Guterres warned that the “climate time bomb is ticking” as he urged rich nations on Monday to slash emissions sooner after a new assessment from scientists said there was little time to lose in tackling climate change.
“The rate of temperature rise in the last half century is the highest in 2,000 years,” he said. “Concentrations of carbon dioxide are at their highest in at least 2 million years. The climate time-bomb is ticking.”
In a recorded address, Guterres described the sixth “synthesis report” from the U.N.’s Intergovernmental Panel on Climate Change (IPCC) as “a survival guide for humanity” and urged developed countries to commit to reaching net zero emissions by the earlier date of around 2040.
The synthesis report summarised findings from three expert assessments published between 2021 and 2022 that looked at the physical science, impacts, and mitigation of climate change. The summary report is designed to provide clarity for policymakers as they consider further action to slash emissions.
“We have the tools to stave off and reduce the risks of the worst impacts of the climate crisis, but we must take advantage of this moment to act now,” said U.S. climate envoy John Kerry.
