Kenneth Richard is talking about a massive cover-up of a global cooling consensus in the 60s-80s over at Pierre Gosselin’s NoTricksZone – chief culprit the infamous Wiki climate change revisionist William Connolley. Coincidentally, I was talking about the global cooling scare on here just a few days ago. I mentioned Schneider in particular who, in a paper co-authored with S. I. Rasool published in 1972 says:
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 . . . . . . 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 ° 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.
Kenneth Richard cites a 1974 paper by Schneider as one of 285 scientific studies which he believes clearly demonstrates an 83% scientific global cooling consensus at that time. Two years on from his earlier study, Schneider still seems convinced that it is the cooling influence of anthropogenic aerosols, not warming CO2, which is the serious threat to global climate. He changed his mind, as is his scientific perogative, as the weight of evidence swung firmly in favour of an overwhelming warming anthropogenic influence (less generously, one might say he noticed that the wind was blowing in the opposite direction, hopped off the cooling bandwagon and swiftly jumped on the global warming bus). Whatever, he was in no doubt in the early 1970s that the earth had cooled considerably during the 1940s-60s:
So, the earth cooled by 0.3C during the 1940s-60s, the Arctic cooled even more dramatically by 1C in just a decade and “some scientists” felt that anthropogenic aerosols might be responsible. ‘Some scientists’ were clearly warning that man’s activities might tip us into a new ‘catastrophic’ ice age, Schneider included.
Fast forward 42 years and we have not just “some scientists” but 97% apparently, warning us that man’s activities might tip us into an unstoppable Thermageddon Age. 30 years of cooling, 42 years of warming. Both blamed on industrial emissions. What’s the difference? The coolists didn’t get their act together in time to capitalise upon a trend which turned out to be temporary. The warmists most definitely did, to the tune of a cool $1.5 trillion. The ‘Pause’ rattled their bandwagon somewhat. Further warming will keep it rolling along very nicely thank you, despite the best efforts of us deniers. Only a 1940s-60s type downturn – or worse – in global temperatures will derail the global warming industry. It’s due in the next decade, starting as early as 2017/18. If it doesn’t happen, book yourself into your nearest cave or prepare for the era of £92.50/MWh carbon free Chinese/French nuclear energy. Because mega-expensive FrogChink nuke, windmills and solar power will be our only salvation on a Greenhouse Earth of which we were warned but which many of us failed to take heed.
