UN chief: Climate change is our defining threat

The head of the United Nations says climate change is “the defining threat of our time” and requires concerted action by the international community.

UN Secretary-General Antonio Guterres says the world may have only five years to take measures needed to meet the most ambitious target of keeping global warming at 1.5 degrees Celsius.

Guterres told leaders, ministers and negotiators at global climate talks in Bonn, Germany, on Wednesday that although this will require sharp cuts in greenhouse gas emissions, the steps are achievable.

He cited data showing major developing countries such as China and India surpassing their emissions reduction goals as evidence that economic growth is possible even while cutting down on fossil fuel use.

Guterres urged leaders to “show courage in combating entrenched interests” in fighting climate change.
