This morning, American Thinker has an article titled "There’s Only One Greenhouse Gas—And It Isn’t CO2". Hint: it's water vapor. Something that climatologist Dr. Roy Spencer stated many times. Some of us might remember him as Rush titled him: "The official climatologist of the EIB Network".
This whole issue is emblematic of the dumbing down of our society. How many people have actually stood on the shoreline of say Lake Superior and realize that a glacier (Laurentide ice sheet) was a mile thick above you only 150 great-grandmothers ago.
