The Cosmogenic Isotope Record and the Role of The Sun in Shaping Earth’s Climate
The defining division between “climate sceptics” and “greenhouse gas warmists” is the role of the Sun in causing Earth’s climate to oscillate. The anecdotal evidence for a significant solar role comes from the observation that during the Little Ice Age (LIA) sunspots were virtually absent from the Sun for a few decades – and in Europe at least it was periodically very cold. The HARD scientific evidence that backs this up comes from cosmogenic isotope variations that provide a record of solar geomagentic activity. It is surprising therefore that The Geological Society of London’s (GSL) 2010 position statement on climate change does not mention the incredible cosmogenic isotope record at all.
The omission was corrected in the 2013 addendum but unfortunately the addendum does not fully represent what the cosmogenic isotope record tells us. This post is a response to the GSL’s addendum, at 3,700 words too long to include as a comment on the original post.

Extensive sea ice and northerly winds must have played a role in the common visits of Inuit to Scottish shores at these times. He was accompanied by ice bergs that drizzled sediment on the ocean floor leaving an amazing record for geologists to study.]
