Climate change is slipping down the international agenda, raising the risk governments will slow their pace in reducing greenhouse gas emissions, the head of a global energy watchdog has told Sky News.
Speaking on the fringes of the World Economic Forum in Davos, Fatih Birol, executive director of the International Energy Agency, said the mood at the Swiss resort seemed to lack the urgency needed to keep global warming to 1.5C.
The organisation he leads works with countries around the world to shape energy policies for a secure and sustainable future.
But Mr Birol said: "I have the feeling that climate change and its urgency is sliding down the agenda.
"The energy crisis is very important - it's crucial.
"The food crisis is very important.
"But the climate crisis is very important as well.
"I don't see the commitment and engagement from people that I have seen in the last few years… It is not something that we can forget and it is a real issue."
Roberta Metsola, president of the European Parliament, argued it was now incumbent on her fellow politicians to address the challenge.
She told Sky News: "We are the last generation of politicians that can address this.
"Previous ones didn't. It's either now or never. Our voters want it from us. Our younger generations want it from us. If we don't decide, we can't leave it to them."
The four-day conference came to an end on Friday.
While it was less well-attended than in previous years, it nonetheless drew in political leaders from around the world.
A notable exception was the UK, which did not send either its prime minister or chancellor for the first time in nearly two decades.
