Prince William thinks the time has come to "take action on climate change"

Speaking to Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson on the 'Outrage + Optimism' podcast, Prince William explained: "The science is out there and is irrefutable. We have the data. So let's stop talking about it and let's actually provide the action.

"I think that's what's going to be really needed over these next ten years."

The inaugural winners of the Earthshot Prize - which is geared towards helping to combat climate change - will be announced at an awards ceremony in London next year.

Meanwhile, Prince William previously hailed Prince Charles' efforts to shine a light on the issue.

He reflected : "He's talked about this for a long time and long before people sort of cottoned on to climate change. So, I've always listened to and learnt and believed in what he was saying.

"But I knew it's a very hard sell, you know, 40 years ago to kind of predict and see some of the sort of slow-moving catastrophes that we were headed towards.'"

Despite some of the pessimism surrounding the issue, Prince William insisted it's not too late to avert a potential disaster.

The British royal - who has Prince George, seven, Princess Charlotte, five, and Prince Louis, two, with the Duchess of Cambridge - said: "I do feel you have to have the urgency and the importance of what's going to happen and the seriousness of what's coming along.

"There are plenty of people talking about that. But I personally feel we must have some hope and some optimism. It's all very apocalyptic about things."
