I recall Rush reading a Time (?) magazine article from the early 70's that quoted several of the same scientists, that are INSISTING we have global warming, INSISTED at that time that the earth was entering a new ice age.
What we have here is a bunch of lemming-like scientists trolling for grant money.
You're right... it all comes down to some scientists (mainly liberals who like feeding at the easy-money trough of forced public support) putting themselves ahead of what is best for America - the TRUTH. Pure and simple greed.
