Carl Sagan was one of the greats of science communication. Often remembered for his epic Cosmos (well worth revisiting, available on You Tube) he was also the instigator of the Pioneer 10 plaque which carries humanity's message across the galaxy. Thus long after you and I have turned to dust Carl Sagan's work will still be on it's interstelllar voyage .
Vloggers have divided up much of Carl Sagan's work into bite sized chunks like 'pale blue dot' which gives an astrophyscist's perspective on our environment . Tear to the eye stuff.
Hat tip to Climate Crocks for finding this film which directly addresses the question of anthropogenic global warming .
Sagan died in 1996 at the age of 62.
2012 and a guest blogger on the Bishop Hill blog lifts a passage from chapter IV of Dr Sagan's book Cosmos and posits that Sagan would have opposed the AGW consensus and the IPCC. A staggeringly cynical use of a widely respected dead scientist to attack the IPCC and make a partisan point. Does make one wonder what next for the Bishop Hill blog , Charles Darwin blogs on Dark Matter perhaps or Euclid's thoughts on the PIP implant scandal?
