William highlighted the visit to the glacier and the challenge of climate change, a major theme of their five-day trip, in a speech the previous evening at a reception hosted by the British High Commission at Pakistan's national monument in the capital, Islamabad.

The Duke and Duchess of Cambridge flew by helicopter to the northern tip of the Chiatibo glacier, where a climate change expert explained how it was retreating.

Pakistan's northern glaciers and those throughout the Hindu Kush and Himalaya region, are an important water store for 250 million people, and another 1.6 billion rely on rivers originating in the mountains, putting many communities at risk as global temperatures rise.

Kate and William later observed damage and emergency response drills in a village in Chitral that had been hit by floods due to glaciers melting. They also vistaed a settlement of the Kalash people, a small indigenous group living in the Chitral region where they met young people and wore colourful local scarves.

Chitabo is one of the around 7,000 of Pakistan's 7,200 glaciers that meteorological officials say show signs of melting, citing data gathered over the last 50 years.
