Murray's talk at Middleburry's

Murray's account of the event.
Video of the students shouting down his lecture. 
Murray's "The Bell Curve" was the first "large" book that I read in English - that was 1995. I really doubt anybody from those shouting youngsters read it.

Climate change

 Just realized that over the time span I have been researching climate change impacts the atmospheric CO2 concentration increased by 20%.
