I disagree.

two facts that are not "junk science"

-- CO2 is a greenhouse gas
-- CO2 levels, as skipdog points out, are at their highest level in hundreds of thousands of years.

Is human-generated CO2 contributing to global warming? Absolutely. Is human-generated CO2 the primary factor in global warming? That is debatable.

Although I can understand people still arguing the causes of global warming, the fact that it is occurring is grounded in a lot of observational evidence. Even the Bush administration is finally coming around to this point of view.
