Maybe this will help you...over the last 800,000 yrs Milankovitch Cycles have caused the Earth to

Heat Up, thus releasing CO2 into the atmosphere, which subsequently decreases as the Cycle proceeds toward Cooling...right now, we are in the very beginning of another Cooling Cycle...yet the range of CO2 concentration has Doubled in the last ~150 yrs, thus increasing global atmospheric and ocean temperatures...the ONLY explanation is Mankind's burning of Fossil Fuels. If you don't believe me, do a Google search on my comments...assuming you want to find the truth about this important issue that affects every single person on this planet...now and for the future.
