Prince Charles of England argues that climate change is responsible for the four-year civil war in Syria, terrorism and the ongoing European refugee crisis that began as a result.

Charles, well known as an environment campaigner, is scheduled to give a keynote speech at the opening of the United Nations summit on climate change in Paris next week, according to The Times Of India.

He expresses concern that disaster would follow if global warming isn't addressed more urgently, in an interview with Sky News, which is due to be aired Monday.

"We're seeing a classic case of not dealing with the problem, because, I mean, it sounds awful to say, but some of us were saying 20 years ago that if we didn't tackle these issues, you would see ever greater conflict over scarce resources and ever greater difficulties over drought, and the accumulating effect of climate change, which means that people have to move," Charles said.

"And, in fact, there's very good evidence indeed that one of the major reasons for this horror in Syria, funnily enough, was a drought that lasted for about five or six years, which meant that huge numbers of people in the end had to leave the land," he added.

Asked if there is a link between climate change and the ongoing conflict in the Middle East, he said: "It's only in the last few years that the Pentagon has actually started to pay attention to this. I mean, it has a huge impact on what is happening."

He also expressed doubt on whether the 118 world leaders who will attend the Paris talks will be able to reach to reach a consensus on limiting greenhouse gas emissions, according to USA Today.

"There's been so many of these conferences that have happened over the years and I think I go back quite a long way on all this," he said. "I haven't been to all of them, but I went to Copenhagen in 2009 and that really ended in disaster, frankly, which is a total tragedy because we've lost all those years in between. There's a lot to catch up on."
