I did polish it up a bit Tuesday evening.}
Though I don't have enough spare time for working on Ridley's folly, I needed to take the time to share this because it's both a good assessment of the state of understanding and because it underscores What A Scientist Sounds Like.
I'm talking about Peter Sinclair's recent post featuring an excellent talk by Professor Richard Alley PhD.

The Weekend Wonk: Richard Alley on Climate History and CO2
Peter Sinclair | Weekend Wonk | August 1, 2015
http://climatecrocks.com/2015/08/01/the-weekend-wonk-richard-alley-on-climate-history-and-co2/At 3:50 a graph caught my eye because it dawned on me that in a way I was basically looking at "Mann's Hockey Stick" 15 years later. That is, after 15 years of accumulating data from all sorts of teams studying all sorts of proxies. This graph includes additional important information, such as solar irradiance, volcanic forcing, other 'forcings' among other information.
Recall the story? Back in the late 1990s a group of researchers lead by Michael Mann, Raymond Bradley and Malcolm Hughes were studying tree rings and glacial ice cores and using them as a proxy for establishing a paleo-temperature record for the past couple thousand years.
