Sen. John Kerry (D-Mass.) said last night that the U.S. was moving too slowly to confront climate change.

The Massachusetts Democrat also said he expected the climate conference in Copenhagen, Denmark, to result in a political agreement with binding emissions reductions.

"We're making decisions too slowly," Kerry told PBS's Charlie Rose. "We are not grappling with the big choices that we face."

"We have to decide what Americans are going to produce and how we're going to create the jobs of the future. And if we approach it the way we've been approaching climate change and these other issues, we are going to be way behind these other countries," he continued.

Speaking of the international climate change conference in Copenhagen next week, Kerry said he expects countries to reach binding conclusions.

"I believe that Copenhagen will come out with a political agreement that will have binding mandatory reductions that people will agree to," Kerry said. "I believe it will come up with a prompt start to those reductions at the beginning of next year or so."

That political agreement would have to be translated into treaty language in the months following the conference.

Meanwhile, Kerry also acknowledged that he would have liked to be secretary of State under President  Barack Obama.

Kerry was reportedly considered for the position, which of course was finally handed to Hillary Rodham Clinton.

"Did you want to be secretary of State?" Rose asked.

Kerry responded: "I think you would be a liar if you sat here and played a game, and said, 'Gee, Charlie, no.' I think it is a great position. But I didn’t sit around and worry about it. That is a very personal decision."
