Media Matters has uncovered an internal Fox News memo put out last year that proves the network deliberately manufacturers doubt about climate change.

At the same time Fox News was helping gin up the "Climategate" controversy last year, managing editor Bill Sammon wrote to his staff:  "...we should refrain from asserting that the planet has warmed (or cooled) in any given period without IMMEDIATELY pointing out that such theories are based upon data that critics have called into question."

With this proof on record, Fox News should fire managing editor Bill Sammon for spinning "unfair and unbalanced" mistruths about climate change.

Fox should also publicly correct its erroneous reporting on Climategate, the pseudo-scandal that broke at the height of key global climate negotiations last year. The scientists involved have been exonerated of wrongdoing several times in independent investigations.

A recent survey found that daily Fox News viewers were “significantly” more likely than non-viewers to believe that most scientists do not believe climate change is occurring. It doesn’t matter what your personal opinion is, this is flat-out wrong. 

Tell Fox News to fire Bill Sammon and set the record straight.
