Justin Webb put it to the environmentalist and former US vice president that he was “joining the dots” and making claims that were “going further” than scientists would.
Mr Gore has hit out at Donald Trump claiming the president has isolated himself over his decision to withdraw the US from the Paris agreement, a pact by 159 nations to deal with greenhouse gas emissions.
Speaking on the Today programme on BBC Radio 4, Mr Gore said looking at current weather conditions was enough to convince work needed to be done.
The Nobel Peace Prize winner said: “Mother nature is the chief advocate for fighting the climate crisis right now.”
But Webb hit back and suggested the former vice president’s second film on tackling climate change, An Inconvenient Sequel, exaggerated facts.
He said: “But that’s the problem isn’t it, you make the case that they’re climate related.
“If I said to you, it’s a cold day in London right now, so there’s no such thing as climate change, you’d say you’re a moron, it’s an idiotic thing to say.
“Yet in your film, you have repeated shots of storms and you, as you put it, join the dots and suggest that they have to be because of man-made climate change.
“You’re going a little bit further than all the scientists would.”
But Al Gore tried to defend his position and said there was “clear evidence”.
He said: “Oh no. Of course the Royal Academy of Science here in the United Kingdom and all of the academies of science throughout the world are virtually unanimous on this and have been for decades.
“You’ve had clear evidence here in the UK, just in the last couple of years, the all-time record downpours and the high temperatures and just this past week in southern Europe, the record high temperatures and fires.
“All of these things are consistent with what the scientific community has been saying for decades.
“But again, mother nature is a more persuasive advocate.”
Mr Gore, who served under Bill Clinton, lashed out at Mr Trump claiming the US would continue to meet its obligations under the landmark Paris agreement despite the US President pulling out of the deal.
The 2000 presidential candidate, awarded for his work on climate change, said the only option was to “work around” Donald Trump.
Mr Trump controversially pulled the US out of the Paris climate change deal, signed in 2015 by 195 countries, in June.
Formally announcing the decision, he said: “We don’t want other countries and other leaders laughing at us anymore.
“This agreement is less about the climate and more about other countries gaining a financial advantage over the United States.”
