TapeCutter writes: In 1958 the US National Academies of Science (NAS) warned the US government that they had detected a robust AGW signal, they have not change their mind on that claim for 57yrs. Like the modern day Al Gore, Frank Capra publicized the possible effects in a popular documentary. Today we have news of a study from Melbourne University claiming the effects of AGW first became evident in the mid 20th century.
In other words the NAS could not have picked up the signal much earlier than they actually did. The fact that the last serious scientific objection to AGW (as a theory) was overcome in the mid 20th century by improving spectrometers in heat seeking missile was a remarkable coincidence, NAS took full advantage of that opportunity.
TapeCutter writes: Gavin Schmidt from realclimate has published an excellent opinion piece on the narrative of the scientific heretic and it's appeal to journalists and the general public.
Quoth TFA — "This idea of knowledge sitting on a knife edge ready to flip whenever some new observation or insight arrives, is the reason why science is so exciting and fascinating. That is the reason why science deserves to be the story, and why journalists should be continuously searching for the 'front page' thought that will allow this story to be told to a wide audience. But all too often the real story is neglected in favour of a familiar well-worn, but inappropriate, trope."
TapeCutter writes: In a paper soon to be published in the Astrophisical journal Australian researchers have estimated the entrophy of the universe is about 30 times higher than current estimates. For those of us who like their science in the form of a car analogy Dr. Lineweaver compared their results to a car's gas tank. He states, "It's a bit like looking at your gas gauge and saying `I thought I had half a gas tank, but I only have a quarter of a tank."
