A new poll shows that Gov. Jerry Brown has a record high 54 percent approval rating with California voters before he heads into a likely re-election campaign next year.

But the poll by the Public Policy Institute of California finds there is less support for the Democratic governor when it comes to climate change. Only 44 percent of likely voters say they approve of how Brown has handled the issue.

The governor has not announced that he's running for re-election next year, but he filed campaign finance reports Wednesday showing he has more than $10 million in his campaign account, and another $3 million in a ballot measure committee account.

The Public Policy Institute's survey is based on interviews with 1,273 likely voters by landline and cellphone from July 9-13. It has a sampling error margin of plus or minus 3.9 percentage points for likely voters.
