Um, I'm afraid the Climate Debate Daily site has a problem -- like much of the media, it does the public a disservice by presenting a "debate" about global warming as if there were equal arguments on each side. Pretty much all scientists now accept that climate change is real and caused to some extent by human activity, except those paid by the oil industry and its friends. According to the Union of Concerned Scientists, "ExxonMobil has funneled nearly $16 million between 1998 and 2005 to a network of 43 advocacy organizations that seek to confuse the public on global warming science."
