We are losing the race' on climate change: UN chief

The UN secretary-general said the commitments made under the Paris climate accord were already "not enough"

The world is "losing the race" against climate change, UN chief Antonio Guterres warned Thursday at the elite Davos forum, demanding bolder action from governments to arrest catastrophic warming.

"Climate change is the defining issue of our time. We are losing the race," he said on the margins of the World Economic Forum in Davos, which has featured much hand-wringing on the crisis this week.
