The Duke of Cambridge has warned that the world risks losing "many of the precious things we care about" if it fails to take action on climate change, as he visits a melting glacier in Pakistan.

The Duke, who travelled to the north of Pakistan on the third day of their tour, said the couple hoped to "use our voice and lend our position" to talk about the environment and climate change.

Praising young people across the world who are "getting very engaged in what's going on", he said: "If we take too long about this we will lose many of the precious things we care about."

He went on to call for “more education, more awareness and political action”.

The Duke and Duchess have spent the day in a remote location in the Hindu Kush mountain range in northern Pakistan, beginning at the Chiatibo Glacier in Broghil National Park.

They were shown how the ice has retreated rapidly in recent years due to global warming in their first opportunity to see a melting glacier in real life.
