Former Vice President Al Gore is pessimistic President Trump will come around on climate issues.

During an appearance on the "Late Show" on Monday night, Gore told host Stephen Colbert he "thought there was a chance" Trump would "come to his senses" on climate issues.

"But I was wrong," Gore said, citing Trump's decision to withdraw from the Paris climate agreement.

"I worried that it would be a disastrous move. But immediately after that all the other countries in the world doubled down and said we're going to do even more," he added.

Other U.S. leaders promising to stick to the commitments of the Paris agreement also gave Gore hope.

Gore visited Trump Tower after the election to meet with Trump and his daughter Ivanka to discuss climate change. Ivanka Trump reportedly pushed her father to stay in the climate agreement, but he announced in June that America would exit the pact.

Gore is currently on tour promoting his latest documentary, "An Inconvenient Sequel: Truth to Power."
