I just wonder how anyone can say that this period of 4.5 billion years of weather history is the way it is supposed to be. It is arrogant to me that anyone alive is smart enough to know how the weather is just right since the globe is in constant state of change. Remember the great lakes? they are there because of global warming. Chicago and New york city were under a mile of ice not long ago, good thing things warmed up. In the 70's the same people where telling us that global cooling was upon us.
