of course...the Earths temp has NEVER been or will EVER be a "Constant", who ever came up with that silly idea...?
a globe, internally heated ( lava),with 'vents'( volcanoes) whirling around Universe at a high rate of speed, and going around a very hot globe (the sun) ,which has out bursts of heat in all directions at different times...some at known cycles of +_ 40 yrs, is to have a constant avg temperature?
