How is global warming different from natural climate cycles? - John
Not to mention I have heard very accurate sources say that the polar ice caps melting is due to a shift in the upper atmosphere what do you say about that? If the ice caps were melting than wouldn’t that increase the amount of fresh water on the earth? And wouldn’t that evaprate much faster and turn into clowds causing more cooling in the future? Why is it that when a volcano erupts it emits so much pollution however that is ok?

Natural climate cycles have a time scale of 100,000 years for the glacial period, or 20,000 for the interglacial. The warming we are now inside has a time scale of 200 years. The only explanation for such an unnaturally fast warming is the very fast increase in CO2 concentration in the atmosphere to levels not experienced in the last 2 million years. This fast increase in CO2 concentration is produced by a massive burning of carbon based fossil fuels: Coal, oil and natural gas.
