Since 1968, Charles has been vocal about the effects of climate change. Since then it has become a mainstream issue. For some, it again becomes a political issue. Charles was one of the supporters of the Paris Climate Agreement in 2015. After Donald Trump took office as the US president, he announced that the US would withdraw from the agreement.
Charles interviewed the CNN journalist during the World Economic Forum in Davos, Switzerland in 2020. He still expressed optimism about the implementation of the Paris Agreement. Charles said, ‘Every month there is a new record of warming. We cannot continue like this. If we give up and allow this situation to continue for a long time, the situation will become more complicated.’
In recent years, Charles has been seen playing a pioneering role in protecting the environment. He urged countries to work with industry to find solutions to combat climate change at the COP 26 conference held in Glasgow in November 2021.
“We know it’s going to cost billions of dollars, not hundreds of millions,” Charles said.
Pointing out that climate change and loss of biodiversity are major threats, Charles said that war-like measures should be taken to deal with them.
