Good to hear from you again Bob!
I did not mean to stir up an off topic debate, just to point out that politics
and science and journalism have turned into a strange brew. There is no such
thing as settled science - history proves this time and again. The scientific
method abhors this kind of closed minded attitude.
I would also add, that in terms of reproducible scientific proof, the
supposedly settled science of the climate models that the man made climate
change movement relies upon for these claims, have proven to be even less
reliable than a five day weather forecast.
We can disagree about political motivation on both sides of this issue, but I
am not aware of any Republicans suggesting that we should stifle the debate.
Yet the LA Times has announced they will no longer publish opposing views, and
the Washington Post received a petition signed by 110,000 people, saying that
the Post should no longer publish anything that challenges the settled science
of Global Warming. This not only runs contrary to the First Amendment, but
reeks of totalitarianism.
