The point is we have had dozens of ice ages over millions of years.... and then it warmed up each time over the millennia.  The questions is, who had "SUV's" that warmed up the planet each time in the last 100,000,000 years?  This is natural, not man-made!  BOTTOM LINE:  don't believe anybody that says "it is YOUR fault, so you owe "us" more taxes, so we can "fix it"!
