In an interview with Science News in 1975, C C Wallen, Head of the Special Environmental Applications Division of the World Meteorological Organization, had this to say about the consequences of the cooling trend since 1940:-

 

The principal weather change likely to accompany the cooling trend is increased variability-alternating extremes of temperature and precipitation in any given area-which would almost certainly lower average crop yields.

 

During cooler climatic periods the high-altitude winds are broken up into irregular cells by weaker and more plentiful pressure centers, causing formation of a "meridional circulation" pattern. These small, weak cells may stagnate over vast areas for many months, bringing unseasonably cold weather on one side and unseasonably warm weather on the other. Droughts and floods become more frequent and may alternate season to season, as they did last year in India. Thus, while the hemisphere as a whole is cooler, individual areas may alternately break temperature and precipitation records at both extremes.

So why are we now being lied to and told the opposite?

    So sad when you realise we have wasted and hidden nearly 40 years of research. Brilliant find Paul. Thanks.

    I have been thinking that the changes we have seen in the jet stream were tied to the PDO atmospheric pressure changes and now this paper makes a direct reference to the cool mode of the PDO (since 1940) and a meridional flow. Thanks, just what I was looking for.
