The review of the book "An appeal to reason:  a cool look at global warming"----  sounds interesting.  Perhaps there is more heat generated discussing global warming making the issue look more scary than real.  The book comes heavily on the establishment for  presenting an exaggerated  picture of a phenomenon which is as natural as anything. The author finds the arguments  not well founded. But a rebuttal to his statements is equally interesting saying" he dosen't have much gunpowder to mount a serious   onslaught".  The truth lies somewhere in between.  The politics shrouded in science is more complex than the science of politics.
