1 Bolt says that I claim that climate has been stable for the past 10,000 years. This is not so. In my book I reprint the graph that documents northern hemisphere climate variability over the past 1000 years, and enter into an extended discussion of well-known variations such as the Medieval Warm Period. Either Bolt has not read the book he is critiquing, or he is lying through his teeth.
