ISLAMABAD: Prime Minister Imran Khan on Thursday warned the world that as ice at poles melted fast and temperatures rose globally, any negligence towards the climate change could put the future generations in danger.

"If the world does not take notice now, I am afraid we will be endangering our future generations," the prime minister said in a video statement at the fourth Austrian World Summit held in capital Vienna.

The prime minister, on the invitation of Arnold Schwarzenegger, former California governor and actor, shared his vision about conserving biodiversity and the steps taken by Pakistan to fight the climate change.

Imran Khan said some 20 years ago, the topic of climate change was taken with skepticism, however, today it had become a harsh reality.

He mentioned the 'cruel face' of climate change for the world in shape of record temperatures in Siberia, ice-melting on poles, rising temperatures in Europe, unprecedented fires ravaging Australia, cyclones and hurricanes.
