Mr Gore is in the United Kingdom for the premiere of his new documentary An Inconvenient Sequel: Truth To Power.
The former USA vice president said this was because Mr Trump's decision to pull the U.S. out of an global agreement to tackle climate change resulted in the rest of the world and individual U.S. states and cities redoubling their commitments.
"It looks like the US will meet its commitments under the Paris Agreement regardless of Trump", says Gore.
Tensions were ratcheted up this week when the US president responded to news that Pyongyang had developed miniaturised nuclear warheads with a drastic warning that he would meet their continued threats with "fire and fury like the world has never seen".
"When he made his statement, I was anxious that other countries might follow his lead and pull out using that as an excuse, but to the contrary the rest of the world - the very next day - redoubled their commitments to stay in the Paris Agreement, as if to say, 'We'll show you Mr. Trump!'"
Donald Trump deserves to be given credit for his handling of the North Korea crisis. On Tuesday the president promised to unleash "fire and fury" on the country if it continued to threaten the US, and doubled down on the remarks Thursday, when he said the military was "locked and loaded". "The previous three presidents were not able to find an adequate solution, so he can't be blamed for all of this".
Gore told Newsweek that Trump's "intemperate comments on North Korea were really unwise".
"As the Secretary-General said in a statement on 1 June 2017, the decision by the United States to withdraw from the Paris Agreement is a major disappointment for global efforts to reduce greenhouse gas emissions and promote global security", said UN Spokesman Stéphane Dujarric.
Gore said he hoped Trump's senior advisers stressed caution.
"I think his intemperate comments the other day did not help the situation", said Gore, "but it's a very hard challenge". "I hope he will listen to them, and I hope their cooler heads will prevail". "But I do think he's an immensely positive force for the environment".
"In my country, so many of our governors - the ones from our larger states included - and so many mayors and business leaders stepped up to fill the gap and said we're still in the Paris Agreement", he told the Thomson Reuters Foundation.
A decade after An Inconvenient Truth brought climate change into the heart of popular culture, comes the riveting and rousing follow-up that shows just how close we are to a real energy revolution.

We certainly need to add one more forward as Diafra Sakho and Andy Carroll can not be relied on to keep fit for much of the season.
