Category 5 Hurricane Irma was the most powerful Atlantic Ocean hurricane ever, with winds that reached 185 miles per hour.
The Foreign Office is advising against all travel to the Virgin Islands, and all but essential travel to Montserrat, Turks and Caicos, and Anguilla.
And while the Virgin founder noted that the islands and the people may have been physically damaged, "their spirit is as strong as ever".
Still, with another storm, Maria, barreling toward the British Virgin Islands, where a hurricane warning is in effect, Branson said the first priority was to "deal with immediate aftermath of that and just making sure everybody is all right". The cost, Branson believes, is all thanks to climate change.
British billionaire Richard Branson said on Tuesday he is in talks to set up a fund to help Caribbean nations recently ravaged by Hurricane Irma replace wrecked fossil fuel-dependent utilities with low-carbon renewable energy sources. "Even as the world faces increasingly shocking climate change-related catastrophes, now is our opportunity to get on top of the problem before it's too late". "Or else we're going to find that year after year these events become worse and worse'".
Last week, Trump was pressed on whether Harvey and Irma, which happened back-to-back, had changed his view on climate change.
The businessman and philanthropist added plainly, "Climate change is real. The whole world knows it's real except for maybe one person in the White House", Branson said. It is the fourth major hurricane of the 2017 season, which still has weeks left to go.
"I've seen first-hand the impact climate change is having", Branson said.
