Fox News has tackled one of the most complex ecoviergy issues—climate change and what should be done about it. The REP Index recognizes that carbon emissions may be causing some global warming. It recognizes, however, that: there are as yet significant uncertainties; that policy must be rigorously market-oriented; and that polices must be effective, not wishful thinking. caem! largely adopts the positions of Bjorn Lomborg in his books Cool It (2007) and Climate Solutions (2010) that monies proposed for climate change policies must be measured against other positive things for which that money could be used. When such a rigorous calculation is made, immediate radical carbon mitigation is a very poor investment and harmful to economic growth and third world aspirations.
