1971 Stunner : NASA And NCAR Knew That Catastrophic Global Warming Was A Farce

Real Science

In 1971, NASA and NCAR’s top climatologists knew that even a massive increase in atmospheric CO2 would produce less than 2 degrees warming. The entire basis of the catastrophic global warming scam has been known to be a fraud from day one.

This is consistent with what radiative transfer models and satellite temperatures show. Without NASA and NOAA data tampering, the entire scam would have collapsed a decade ago.

  1. there’s more . Abstract. Effects on the global temperature of large increases in carbon dioxide and aerosol densities in the atmosphere of Earth have been computed. It is found that, although the addition of carbon dioxide in the atmosphere does increase the surface temperature, the rate of temperature increase diminishes with increasing carbon dioxide in the atmosphere. For aerosols, however, the net effect of increase in density is to reduce the surface temperature of Earth. Becuase of the exponential dependence of the backscattering, the rate of temperature decrease is augmented with increasing aerosol content. An increase by only a factor of 4 in global aerosol background concentration may be sufficient to reduce the surface temperature by as much as 3.5 deg.K. If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age.

    The rate at which human activities may be inadvertently modifying the climate of Earth has become a problem of serious concern 1 . In the last few decades the concentration of CO2 in the atmosphere appears to have increased by 7 percent 2 . During the same period, the aerosol content of the lower atmosphere may have been augmented by as much as 100 percent 3 .

    How have these changes in the composition of the atmosphere affected the climate of the globe? More importantly, is it possible that a continued increase in the CO2 and dust content of the atmosphere at the present rate will produce such large-scale effects on the global temperature that the process may run away, with the planet Earth eventually becoming as hot as Venus (700 deg. K.) or as cold as Mars (230 deg. K.)?

    We report here on the first results of a calculation in which separate estimates were made of the effects on global temperature of large increases in the amount of CO2 and dust in the atmosphere. It is found that even an increase by a factor of 8 in the amount of CO2, which is highly unlikely in the next several thousand years, will produce an increase in the surface temperature of less than 2 deg. K.

    However, the effect on surface temperature of an increase in the aerosol content of the atmosphere is found to be quite significant. An increase by a factor of 4 in the equilibrium dust concentration in the global atmosphere, which cannot be ruled out as a possibility within the next century, could decrease the mean surface temperature by as much as 3.5 deg. K. If sustained over a period of several years, such a temperature decrease could be sufficient to trigger an ice age!
    It was clearly not enough to merely warn of an impending Ice Age, but he also blamed it’s potential onset on human activities causing aerosol discharge into the atmosphere. After all, every disaster must have a scapegoat. In fact, aerosol discharge into the global atmosphere has not lessened in any way. It has, if anything, increased. This means that Schneider’s conclusions would be just as valid today.

    Note how he also discounted the countervailing effect of carbon dioxide, claiming that even an 8-fold, or 800%, increase in CO2 would give very little warming and would, of itself, raise temperature less than 2 deg. In view of the fact that CO2 has so far risen only 25% since the Industrial Revolution, this would suggest that Schneider saw little warming potential in CO2 at all – in 1971. This makes his later conversion to the gospel of CO2-induced Global Warming all the more inexplicable, given that atmospheric radiation physics are the same today as then.

    In 1971, Schneider claimed that an 800% increase in CO2 would be needed to raise global temperature by +2 deg. By the late 1980s, he promoted the UN view that a mere 100% increase in CO2 would be enough to raise temperature by +1.5 to +4 deg.

    In 1971, Schneider promoted the idea that the next Ice Age was imminent. By the mid-1980’s and into the 1990s, he equally vigorously promoted the idea that world was about to suffer a catastrophe caused by Global Warming.

    In both cases, Schneider was publicly active in promoting both views, wheras other scientists who may have had a change of view due to new information, did so in the relative privacy of the scientific community, avoiding unnecessary publicity. Not so with Schneider. He revelled in publicity, and promoted both viewpoints at different points in time with equal enthusiasm.
