"No one has denied the existence of natural cycles. Quite the contrary. The point is that what is known of natural cycles cannot explain the warming trends and other climate anomalies of the 20th and 21st centuries."

Genius, explain why these centuries are any different from earlier centuries in terms of climate anomalies? And please do not drag out the Industrial Revolution as the answer why the weather/climate has "changed." It has always changed and is in a constant state of change.

At some point you need to reexamine your arguement and your blind faith in all the global warming garbage. There are entire books that debunk it and all the rest of the Green garbage that hides an eco-fascist agenda.
