To Virgin's Richard Branson - A Challenge to Debate Natural Climate Change

 Richard Branson, founder of Virgin this-and-that, wrote on the website: " And climate deniers need to be called out, debated and rallied against; the science is clear enough now." 

So I put the following into his comments section: 

Hi Richard. I have had a standing public offer to debate in the affirmative that "present climate change is natural" for over five years, and no one has accepted my offer. I have exposed all of my arguments to potential opponents - that this is the coolest warm period of the five warming periods since the end of the Ice Age a bit over 10,000 years ago, and Greenland ice cores that show that 90% of the past 10,000 years were warmer than any of the past 100. At the current warming rate we have a long way to go just to get back up to the average temperature since the end of the Ice Age. That would still leave us much cooler than the Eemian interglacial (warmest period) 125,000 years ago, which was followed by a 100,000-year glacial period (our last Ice Age). All of these are proven facts, none are controversial or conjectural, and all are (apparently) not known by you and others, who I label "natural climate change deniers." Will you debate me?
