COP21: Arnold Schwarzenegger says leaders 'must act now on climate change'

World leaders should focus on ways to use new technology to deal with climate change, former California Governor Arnold Schwarzenegger has said.

Speaking to the BBC's Roger Harrabin at the COP21 climate summit in Paris, the Hollywood star urged politicians not to defer action on global warming.

"It's not 20 years from now. Right now, seven million people are dying every year. Nineteen thousand a day...that is alarming. And everyone in government has a responsibility to protect the people....they have to do something about it."
