Of course business firms would pay to deny the truth.

However, we have nothing to replace fossil fuels on a permanent basis--yet Obama and Hilary want to shut down coal plants putting many people out of work.  I also have difficulty believing Obama's concern about the environment when he flew in air-force one to a climate change summit.  How much carbon did air-force one dump into the atmosphere?  Oh, that's right--I forgot--liberalism isn't for the liberal, it is for everyone else.  

Any "scientific discoveries"' with regard to climate change need to be balanced against present needs.  We cannot just throw out fossil fuels without another viable alternative.  Wind, solar, etc are helping but they aren't there yet.
