I noticed Joe Bastardi had recently put the above chart (4,500 years of Global Temperatures) out as a Tweet. I have posted this chart before at CR and thought It was worth another display. This time I have highlighted the main message and also expanded the last couple of decades.
Piers Corbyn's take on this, is that.... Whenever Solar Radiation has Decreased Volcanic Activity has Increased
The original analysis or I should say observation stated in the RED BOX area...."Whenever Solar Radiation has Decreased and Volcanic Activity has Increased, Global Temperatures Suddenly Plummet, often within Weeks or Months."..the trouble with that statement is that it makes it look as if the Volcanic Activity on Earth Changes the level of Solar Radiation on the Sun!!....click source for bigger image
