"It is premature to conclude that human activities–and particularly greenhouse gas emissions that cause global warming–have already had a detectable impact on Atlantic hurricane or global tropical cyclone activity."  Republican denier propaganda?  No.  That is lifted from a NOAA (our experts on weather) publication which was updated just 16-days ago.  How you come down on the politization of global warming depends on which scientists you listen to.  A group at MIT has concluded that the limitations of technology that reduce solar energy's viability will be overcome in a couple of decades.  Scientists also tell us that natural gas (NG) should replace coal in generation of electricity.  It is not only cleaner, but about one third more efficient.  Green energy activists fear that NG use would make us complacent as the air became cleaner and greenhouse gases were produced at a greatly reduced rate.  So, we are told to not listen to the scientists who say convert.  Denial is universal.
