Like a simple parlor trick, the networks are able to make skeptical scientists vanish, at least from the eyes of their viewers.

In some cases, the broadcast networks have failed to include such scientists for years, while including alarmist scientists within the past six months. ABC, CBS and NBC’s lengthy omission of scientists critical of global warming alarmism propped up the myth of a scientific consensus, despite the fact that many scientists and thousands of peer-reviewed studies disagree.

CNN's Lou Dobbs opened this segment by saying this was a CNN exclusive, something you wouldn't see anywhere else. And unfortunately, he was right for the most.

The Jan. 13 broadcast of CNN's "Lou Dobbs Tonight" explored the possibility that earth isn't warming, but is, in fact, cooling.

Dobbs cited National Oceanic and Atmospheric Administration data dating back to 1880 which showed a spike in mean temperature over land and ocean. However, Joseph D'Aleo, the executive director of International Climate and Environmental Change Assessment Project (ICECAP) questioned that data by comparing it to more modern reliable satellite data, when ask if he "quibbled" with the NOAA data's representation.

"Yes, I do," D'Aleo replied. "In fact, if you look at the satellite data, which is the most reliable data, the best coverage of the globe - 2008 was the 14th coldest in 30 years. That doesn't jive with the tenth warmest in 159 years in the Hadley data set or 113 or 114 years in the NOAA set."
