Who says past politicians can't bring about change and new ideas?

California Governor Jerry Brown has made history after being sworn in for a record-breaking fourth term.

In his inaugural speech, Democrat Mr Brown, 76, outlined ambitious targets for climate change in the most populous US state.

Jerry Brown first served as governor in the 1970s and 80s and returned for another term in 2011.

Since then, he has been widely credited with turning around California's finances.

Mr Brown told the audience at the state Capitol in Sacramento that California was at a crossroads.

"With big and important new programmes now launched and the budget carefully balanced, the challenge is to build for the future, not steal from it," he said.

Jerry Brown defeated Republican challenger Neel Kashkari in November in a landslide re-election victory.
