The ad is running in Oregon ahead of the state's primary and was released ahead of a speech McCain will give on climate change today in Portland. The McCain camp is highlighting the Arizona Senator's stance on global warming as it kicks off its general election campaign.

The issue is thought to be a winner for McCain as the campaign moves to attract independents and siphon off younger voters from Barack ObamaBarack ObamaOvernight Finance: GOP divided over welfare cuts in budget | Lawmaker loses M on pharma stock he pitched | Yellen says another financial crisis unlikely in our lifetimes Why UK millennials voting for socialism could happen here, too Overnight Regulation: EPA moves to repeal Obama water rule | Labor chief to review overtime rule | Record fine for Google MORE.

McCain is careful in the ad though to make clear that he does not think "high taxes and crippling regulation is the solution."

Here is the transcript:

Oil and food prices out of control,
Climate change wreaks havoc with deadly weather.

Another denies the problem even exists.
There's a better way.
