Two-thirds of Americans want the United States to join an international agreement to fight climate change, a new poll found.

The survey, from the New York Times and CBS, could provide a tailwind to the United Nations talks that launched Monday in Paris, where world leaders plan on finalizing such a global pact.

{mosads}A majority of Republicans in the poll do not want the U.S. to join an international agreement.

But overall, 63 percent of Americans said they support domestic policies to reduce greenhouse gas emissions, including most Republicans.

The poll and others like it have found support among people in the U.S. for policies to cut the amount of carbon dioxide and similar gasses being released into the atmosphere, and Monday’s findings show that that support extends even to international policy.

It stands in contrast to congressional Republicans, who are nearly united in their attempts to stop President Obama’s climate policies.

“It would obviously be irresponsible for an outgoing president to purport to sign the American people up to international commitments based on a domestic energy plan that is likely illegal, that half the states have sued to halt, that Congress has voted to reject and that his successor could do away with in a few months’ time,” Senate Majority Leader Mitch McConnell (R-Ky.) wrote in a recent Washington Post piece.

In another poll out Monday, the Washington Post and CBS found a majority of Americans agree that climate change is a serious problem, but the numbers are declining.

Sixty-three percent of that poll’s respondents said climate change is serious, down from 69 percent in June.

At 81 percent, Democrats were far more likely in the Post poll to say that climate change is serious, compared with 43 percent of Republicans.

A slim majority of respondents, 51 percent, said there is “a lot of disagreement among scientists” about the existence climate change, down 11 points from 2009.
