With President Obama on his way to Copenhagen to address the climate conference, some politicians have decided the President needs company.

When President Barack Obama takes part in the high-level talks of the UN conference on climate change next week, his political opponents will be there too, showing the world why the President has had trouble making a stronger commitment to reduce greenhouse gas emissions.

On Tuesday, a group of House Republicans said they will travel to Copenhagen as part of a congressional delegation of about 20 members led by House Speaker Nancy Pelosi, a Democrat who supports strong action to limit greenhouse gases.

Republican Congressman James Sensenbrenner Jr., of Wisconsin said Tuesday that he was tasked with choosing the Republican lawmakers to go to the climate summit with the Pelosi delegation.

His choices include Representatives Joe Barton of Texas, Darrell Issa of California and Marsha Blackburn of Tennessee, all climate skeptics and deniers.

Republican climate skeptics such as Senator James Inhofe of Oklahoma and Wyoming Republican Senator John Barrasso also are on their way to the climate summit.

Sensenbrenner, the ranking Republican on the House Select Committee for Energy Independence and Global Warming, said he will tell world leaders that despite promises made by President Obama, no new laws will be passed in the United States until “scientific fascism” ends.

There was a time when it was said that partisan politics should end at the nation’s borders. Of course, there was a Republican president then, and that’s different. Imagine the fury, though, if, on an international trip, President Bush had been accompanied by Democratic politicians who denounced his policies and pledged to never let them happen.

Beyond that, the use of scary, meaningless buzz words like “scientific fascism” is a pretty good example of the level of the climate change deniers and their Republican allies’ rhetoric. Lacking facts, they resort to distortions and histrionics intended to confuse the issues. The scary part is that to a large extent they are achieving their goal. Having the nerve to follow a president and denounce his policies in foreign countries is a measure of how confident they feel in their ability to follow their tactics and achieve their goal; the prevention of any meaningful climate legislation in the United States, and by extension, internationally.
