McCain, who has led congressional efforts to fight global warming in the past, says he has listened to New Hampshire voters on the issue.

"Not everyone heard you, but I did," McCain says in the ad. McCain emphasizes global warming as a national security issue as well as an environmental one in the 60-second radio spot.

In January McCain reintroduced climate legislation with Sen. Joe Lieberman (I-Conn.), with Democratic presidential hopeful Sen. Barack Obama (Ill.) as an initial cosponsor.
