In the spot, McCain tells voters he believes climate change is real – but suggests that doesn't mean "high taxes and crippling regulation" are the answer to the problem.
"Our environment in peril, oil and food prices out of control, climate change wreaks havoc with deadly weather," an announcer says as the spot opens. "One extreme thinks high taxes and crippling regulation is the solution. Another denies the problem even exists. There's a better way."
McCain then begins to speak. "I believe that climate change is real," he says. "It's not just a greenhouse gas issue. It's a national security issue. We have an obligation to future generations to take action and fix it."
