In an effort to save their funding and reputations, climate scientists are currently trying to blame jet stream dips on global warming. But in 1975 scientists knew that they were caused by global cooling.

During cooler climatic periods, however, 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. If global temperatures should fall even further, the effects could be considerably more drastic. According to the academy (National Academy Of Sciences) report on climate, we may be approaching the end of a major interglacial cycle, with the approach of a full-blown 10,000-year ice age, a real possibility
