This story is huge. America’s prestigious National Academy of Sciences (NAS) and related government bodies found no greenhouse effect in Earth’s atmosphere. Evidence shows the U.S. government held the smoking gun all along – a fresh examination of an overlooked science report proves America’s brightest and best had shown the White House that the greenhouse gas effect was not real and of no scientific significance since 1979 or earlier.*

Unwittingly, the U.S. National Academy of Sciences (NAS), the National Academy of Engineering, the Institute of Medicine, and the National Research Council have all dealt climate alarm it’s biggest ever blow. Their killer evidence had been hidden in plain sight for 33 years until uncovered by a team of maverick climate researchers.

All those global warming skeptic Christmas wishes have come at once wrapped in the NAS document, ‘Carbon Dioxide and Climate: A Scientific Assessment,‘ a joint publication from 1979 commissioned on behalf of the U.S. government. This amazing story ties in perfectly with all the big climate news chatter this past week about the revelations from the leaked draft report (AR5) of the UN’s International Panel on Climate Change (IPCC).

The leaked IPCC draft admits it has had to ratchet down yet again the climate sensitivity it expects to find from carbon dioxide (CO2). No wonder the IPCC is today having to retreat over CO2 sensitivity – the trace gas can’t be any factor in our climate if there is no greenhouse gas effect to begin with!

Readers can browse for themselves online the 13,000-word 33-year-old U.S. government report that details the role of carbon dioxide and how it might impact climate. You will see that while CO2 is mentioned no less than 112 times, as you’d expect, nowhere in those 13,000 words will you find ANY mention of the greenhouse gas effect/theory. Scientists at PSI who have carefully studied the document assert this to be the most compelling physical evidence ever found proving the GHE as nothing more than a modern (post-1979) political construct – a veritable sky dragon now well and truly slain. After studying the report PSI expert Hans Schreuder adroitly characterizes the tone of it’s authors: “the main theme that jumps out at me is “we don’t know enough.””

The NAS study was commissioned by the U.S. government to address the best science of the day on the role of carbon dioxide in atmospheric physics and is the perfect seasonal accompaniment to the leaked IPCC admission that climate sensitivity to carbon dioxide (CO2) is once again lower than all the experts predicted – now we know why!

Because of it’s total omission from this key report, any rational human being will be forced to infer that America’s brightest and best in climate science knew as far back as 1979 there was no greenhouse gas effect for CO2 to impact. The report was the distillation of the best climate science from that era. It examined all aspects of how CO2 might alter the temperature of the atmosphere. Popular Canadian skeptic climatologist, Dr. Tim Ball and climate researcher, Derek Alker, both of Principia Scientific International (PSI) recognized the significance of the NAS publication straight away. Acting on their suggestion this author obtained a download copy from the NAS website and ran it through a full word search to confirm the numbers. Readers can check for themselves. There is ZERO mention of any greenhouse gas effect as a factor on our climate.

Now let’s be clear on this. No governmental scientific body entrusted to present the best available evidence on the impacts of CO2 on Earth’s atmosphere would omit to make any mention of the so-called ‘greenhouse gas’ effect unless they did not consider it a factor – however small. But omit it they did.

So, if climatologists are to be accorded the prestige of being the best arbiters of what mechanisms are most likely driving our climate why is there such a huge discrepancy between what science knew 30 years ago and what we are being told today?

One crucial factor here is credibility. What we can be sure of is that the cream of U.S. climate science in the 1970’s had no political axe to grind. Back then the political hullabaloo about man-made global warming took another decade to gather momentum. As such this pristine and untainted evidence provides skeptics the world over with an unequivocal smoking gun to challenge the man-made global warming scam.

We can now say with great confidence that no serious mainstream climate scientist (up to the current generation of rent seekers) gave the GHE the time of day. This new revelation vindicates what experts like Tim Ball have been saying all along: the GHE was already debunked by Professor H. W.Woods in 1909.

I asked senior members of the 200-strong Principia Scientific International who had worked in meteorology or climate science to recall when they first saw the ‘science’ of the GHE emerge onto the radar in universities, schools and national science academies.

PSI co-founder, Dr. Martin Hertzberg recalls:

“I was trained and served as a forecasting and research meteorologist for the U.S. Navy from 1953-1956. The term “greenhouse gas” never appeared in any of the texts or articles I studied during that period, nor did I or any of my fellow meteorologists ever use the concept in either short term or long term weather prediction.”

While Dr. Tim Ball confirms:

“As I recall the original greenhouse effect concept was created as a teaching analogy that was adopted and adapted into the hypothesis. Carl Sagan and Hansen were messing around with the aerosol issue because of the alarmist threat of nuclear winter. This proposed that with a global nuclear war so much dust would be put into the atmosphere sunlight would be blocked driving the world into a snowball earth. The idea was later shown to be theoretically incorrect and disappeared but not without leaving residue such as Hansen’s focus on aerosols and soot. This created his pathological hatred of coal that is the broad theme running through his career. He came to world attention because Gore and Senator Wirth heard about him and brought him to testify before Gore’s Committee in 1988.”

PSI is appealing for more anecdotal evidence from other professionals and scientists the world over who studied in, or were connected to, climate and meteorology studies before the 1980’s. PSI’s aim is to forensically compile a trace line back to where national science bodies and universities went over to the ‘dark side’ to sound the alarm over bogus greenhouse gas ‘science.’

Sane minds will now put all the telling pieces of evidence together and understand why the most modern of science instruments shows little if any climate sensitivity to CO2; while climatologists knew in 1979 the greenhouse gas effect wasn’t even a consideration. If there was to be found killer evidence to expose this scam this surely must be it.

—— UPDATE ——-

John Cook (Skepticalscience.com) and other GHE fanatics have rushed here to post a swath of comments to berate me that I’ve been misleading in my article (above). It is they who are being misleading. Settled science requires settled nomenclature.

The very fact no mainstream science body dared tout the greenhouse gas theory by name in 1979 is because: (a) they lacked the confidence in the science to call it as such (b) they well understood that the greenhouse gas ‘theory’ had already been refuted by RW Woods (1909) and affirmed as such by the American Meteorological Society (1951) in its Compendium of Meteorology (Brooks, C.E.P. “Geological and Historical Aspects of Climatic Change.” pp. 1004-18 (at 1016)).

The AMS was adamant that the very idea that CO2 could alter the climate “was never widely accepted and was abandoned when it was found that all the long-wave radiation [that would be] absorbed by CO2 is [already] absorbed by water vapor.”

The cold, hard facts are in black and white and the revisionists of science history have failed to bury the truth despite billions of dollars in resources and virtual ownership of the media.
