Argument: If the earth was following natural trends, we should be experiencing a cooling trend now
- "How to Talk to a Climate Sceptic guide, How to Talk to a Climate Sceptic guide". February 23, 2006 - "There is a fine historical example of a very dramatic and very regular climate cycle that can be read in the ice core records taken both in Greenland and in the Antarctic. A naive reading of this cycle indicates we should be experiencing a cooling trend now, and indeed we were very gradually cooling over the length of the preindustrial Holocene, something around .5C averaged over 8000 years. It is informative to compare those fluctuations to today's changes."
