Britain's Prince Charles, who is to give a speech at the start of the UN climate summit in Paris next week, said in an interview out on Monday that the war in Syria could be linked to global warming.
Charles also said there was "a real possibility of nature's bank going bust" - just as financial giants did in the 2008 crisis - and warned a deal on cutting emissions would be "very difficult."
"After the conference, it's going to be very difficult I think to get agreement on the necessary reductions and the necessary actions that need to be taken to keep global warming at two degrees, or ideally below.
Still reeling from the worst terrorist attacks in French history, Paris will host nearly 140 world leaders gathering next week to spearhead a climate pact tasked with keeping Earth livable for humanity.
