This is a guest post by Greenpeace USA's Kevin Grandia, former DeSmog Managing Editor.
Christopher Monckton,  well known for his wacky behavior  attempting to deny the scientific realities of climate change, has now moved on to look into the conspiracy theory around whether US president Barack Obama was actually born in the United States!
Monckton, decked out in an American flag shirt, fire arm on his hip and a cowboy hat, tells the interviewer that:
My purpose in being here [in Arizona] is to have a further look into whether the president of the United States is the president of the United States. Now you might say, what has this got to do with someone from Britain… I am here because I am curious. As a peer of the realm I am allowed to stick my long aristocratic nose into anything I want to stick it in.
Seriously, you can't make this stuff up. Here is the video:

Monckton recently spoke at the Heartland Institute's climate denier conference. As part of that conference, an outrageous ad campaign ran by Heartland  just prior to the conference equated anyone who believed in climate change to Osama Bin Laden, the Unabomber and the mass-murderer Charles Manson.
TAKE ACTION!  Nucor, one of the largest steel producers in the US, funds the Heartland Institute and we are calling Nucor's CEO to end funding to the Heartland Institute.
