How is global warming different from natural climate cycles? - John



Posted on 27 February 2009  | 
Why is it that all the “climate change” or “global warming” blamed on people instead of the earths natural cycles?

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.
