Climate time-bomb: The world is running out of time to avoid catastrophe, new UN report warns.

According to a new UN-backed report, the world is rapidly approaching catastrophic levels of heating with international climate goals set to slip out of reach unless immediate and radical action is taken.

“The climate time bomb is ticking,” said António Guterres, Secretary-General of the United Nations, in a statement to mark the launch of the Intergovernmental Panel on Climate Change’s synthesis report on Monday. “Humanity is on thin ice – and that ice is melting fast,” he added.
