The people who push these models are liars. We have busted them lying on countless other 'scientific' endeavors. Why would these liars start telling the truth now?
Global warming is a means to a political end. The left wing anti-American folks use global warming to push anti-capitalist policies. Just look at the idiots who support the pseudoscience of global warming.
So CO2 is NOT a greenhouse gas? You better tell NOAA and every climate scientist on earth. You must have found something they have not.

American Meteorological Society
"It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide." (2012)7
American Physical Society
"The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now." (2007)8
The Geological Society of America
"The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s."
