The Sun drives climate, not CO2

In a recent blog I referred to Fritz Vahrenholt’s book “The Neglected Sun”.  I’ve been aware of this book for some time, and I’ve met the author a couple of times in Brussels.  It was first published in the original German as “Die Kalte Sonne” (The Cold Sun), but its English title emphasises its key premise: that the IPCC, in attributing climate change primarily to CO2, has ignored the Sun, which Vahrenholt argues has both a larger and a better-proven impact on climate.
