Here's how Republicans spun it:

One Senate GOP aide questioned why Democrats were “trying to embarrass Republicans on climate” rather than offering substantive proposals, such as Whitehouse’s proposed carbon tax or a version of their party’s failed cap-and-trade emissions legislation.
“Democrats are stuck in messaging mode,” the aide said.

Still, even Schatz’s language and the inclusion of phrasing that humans were “significantly” responsible for climate change drew some Republican votes, despite the plea from Alaska Republican Sen. Lisa Murkowski that the inclusion of that word merited voting the measure down. Those five Republicans were Sens. Kelly Ayotte (N.H.), Lamar Alexander (Tenn.), Susan Collins (Maine), Lindsey Graham (S.C.) and Mark Kirk (Ill.).

“It’s okay with me if they do messaging if it makes them feel better,” Sen. John McCain (R-Ariz.), who voted for the GOP proposal that humans affect the climate, said in an interview before the votes. As for global warming, he added: “I don’t think anybody disputes that it’s real. The question is what you do about it.”

No one is trying to embarrass anyone. We're just getting the record clear on who believes in science and who believes in Koch. Now we know.
