The president's recently formed grass-roots campaign operation revealed Thursday that it plans to attack Republicans who question radical global warming hype, dubbing them "crazy" purveyors of "far-fetched conspiracy theories."

In a fundraising memo from President Obama's re-election campaign manager, Organizing for Action slammed "climate deniers" and their doubts, which Jim Messina compared to the nutty things a crazy uncle would say at Thanksgiving dinner.

After listing some of the arguments critics make against the president's drive to use regulations and taxes to curb carbon dioxide emissions he believes are contributing to global warming, Messina wrote: "Sounds like things your crazy uncle would say at Thanksgiving dinner, right? You'd be wrong. These are all statements made by current elected officials in Congress, folks whose votes have the power to make an actual difference on this issue. These climate deniers need to be called out ?-- and you're the only ones who can do it."

Friend ?--

Take a look at these statements on climate change -- give 'em a good read through and see what you think:

"Global warming has become a religion for many back here in Washington. To this crowd, there are no greater or more urgent problems anywhere. They worship at the alter [sic] of carbon generation and reduction."

"Nobody really knows the cause ... the earth cools, the earth warms ... It could be caused by carbon dioxide or methane. Maybe we should kill the cows to stop the methane, or stop breathing to stop the CO2 ... Thousands of people die every year of cold, so if we had global warming it would save lives ... We ought to look out for people. The earth can take care of itself."

"I'm also old enough to remember when the same left-wing part of our society was creating a global cooling scare in order to generate funds for their pet projects. So 30-some years ago the big scare was global cooling, and once they drained that [topic], they shifted to global warming."

"[Scientists] are making up their facts to fit their conclusions. They've already caught them doing this."

Sounds like things your crazy uncle would say at Thanksgiving dinner, right?

You'd be wrong. These are all statements made by current elected officials in Congress, folks whose votes have the power to make an actual difference on this issue. These climate deniers need to be called out -- and you're the only ones who can do it.

Add your name to join the team that's going to hold these deniers accountable.

OFA will be out there making sure that the people saying these things are called out -- and the people who sidestep the facts are forced to step up and say what they actually believe is going on with our climate.

Look, our crazy uncles aren't the problem. But these members of Congress are using these far-fetched conspiracy theories as an excuse for not taking action on an issue that affects our environment, our economy, and yes, the planet our children and grandchildren inherit.

Climate change is real, and we're not going to get anywhere on the issue until these guys admit that.

If you and I don't say anything, nothing will change in Washington.

Help climate deniers in Congress see the light and take a step toward progress. Say you'll help hold them accountable:
