Feel free to cite the actual scientific papers predicting global cooling, as opposed to media hype about some speculation at the time. [david_thornley]
... the National Academy of Sciences itself was convinced enough of the "Global Cooling" scare to actually publish a call for immediate action (Science News, Jan. 25 1975, p. 52).
... [Jane Q. Public, 2014-12-16]
As for the mentioned announcement it is in THIS issue of Science News, in the article "NAS Warning On Climate Changes". Exactly as mentioned in the "Chilling Possibilities" article that is linked to in the page that I originally linked to, and EXACTLY as I stated it. The "NAS Warning On Climate Changes" article itself is behind a paywall. If it weren't, I would have linked to it directly. [Jane Q. Public, 2014-12-16]
Okay, so you read a blog which linked to an article which mentioned an announcement by the NAS. Then you responded to David Thornley's request for actual scientific papers predicting global cooling by saying "the NAS was convinced enough of the "Global Cooling" scare to actually publish a call for immediate action."
Did you ever think it might be educational to actually read that NAS report first-hand rather than relying on third-hand interpretations of interpretations? If you did, you'd discover that the 1975 NAS report (PDF) "Understanding Climate Change: A Program for Action" doesn't predict global cooling. Quite the opposite! Read their words:
"Of the two forms of pollution, the carbon dioxide increase is probably the more influential at the present time in changing temperatures near the earth's surface (Mitchell, 1973a)."
"The corresponding changes of mean atmospheric temperature due to CO2 [as calculated by Manabe (1971) on the assumption of constant relative humidity and fixed cloudiness] are about 0.3C per 10 percent change of CO2 and appear capable of accounting for only a fraction of the observed warming of the earth between 1880 and 1940. They could, however, conceivably aggregate to a further warming of about 0.5C between now and the end of the century."
How ironic! Instead of predicting global cooling, the NAS actually predicted "about 0.5C" of CO2-based warming between 1975 and 2000. To see how their prediction fared, let's plot HadCRUT4 over that timespan. The raw data shows warming of 0.47C from 1975 to 2000, which rounds up to 0.5C.
So that 1975 NAS report wasn't predicting global cooling! Its warming prediction was actually fairly accurate, and was certainly within the statistical uncertainties.
Again, that's probably why the National Academy of Science’s 1979 Charney report estimated climate sensitivity as 1.5C to 4.5C and said “If carbon dioxide continues to increase, [we] find no reason to doubt that climate changes will result, and no reason to believe that these changes will be negligible.”
While Jane tries to explain why that NAS report predicting about 0.5C of CO2-based warming by 2000 was actually predicting global cooling, he should also consider addressing this issue with his basic thermodynamics:
But net radiative power out of a boundary around the source = "radiative power out" minus "radiative power in", so the equation Jane just described also says:
NO!!!!! As I have explained to you innumerable times now, you can also consider your heat source, by itself, that "sphere". The only NET radiative power out comes from the electrical power in. Further, the cooler walls do not contribute any of that NET power out. That's what net means. [Jane Q. Public, 2014-12-16]
As I suspected, Jane disputes the definition of the word "net". Jane didn't get his nonsensical definition from any of his textbooks, because in physics, net radiative power through a boundary around the source = "radiative power out" minus "radiative power in".
That's what net means. But after it became clear that Jane is hopelessly confused about the very term "NET" which he keeps capitalizing, I explained conservation of energy in a way that didn't require using that troublesome word. Draw a boundary around the heat source:
power in = electrical heating power + radiative power in from the chamber walls
power out = radiative power out from the heat source
Since power in = power out through any boundary where nothing inside is changing:
electrical heating power + radiative power in from the chamber walls = radiative power out from the heat source
Notice that this equation is equivalent to the equation Jane just described, but only if Jane uses the physics definition of the word "net". And in order to derive it, I didn't even have to use that word which has Jane hopelessly confused. All I had to use was conservation of energy.
