I did polish it up a bit Tuesday evening.}
Though I don't have enough free-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, 2015At 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.
As for Mann et al. original papers, their data, it's interpretation and graph itself have all stood the test of time, though you'd never know it listening to a Republican.
