Dig and CF,
Once again you've caught my attention with your interest in the "threat" of "global warming" and mankind's role in either "creating it" or "moderating it."
As a professional engaged in "energy efficiency," i.e., energy conservation in buidings for over forty years, and as a NIMBY living as a "near hermit" on a 40 acre tract of land high in the Appalachian Mountains for over 40 years, I have become appalled at the preponderance of greed and associated politicization of the debate over "global warming."
To begin with, government forums are not the appropriate arena to engage in such debates. In fact, the only reason for public debate over such issues can only be atributed to personal gain and should not be assumed as for the benefit of mankind.
Considering the geometric progression of our energy consumption over the past several decades, energy condensation and storage should be the quest of our brightest scientific minds while the general population focuses upon conservation.
