Pakistan is home to more than 7,000 glaciers, more than anywhere else on Earth outside the poles.

Rising global temperatures linked to climate change are causing the glaciers to rapidly melt, creating thousands of glacial lakes.

The government has warned that 33 of these lakes -– all located in the spectacular Himalaya, Hindu Kush and Karakoram mountain ranges that intersect in Pakistan –- are at risk of bursting and releasing millions of cubic metres of water and debris in just a few hours, like in Hassanabad.
