National Geographic : 1967 Feb, Page 194 - 'These records show that Alaska's ice masses advance and retreat in direct correlation with cyclic changes in sunspot numbers. Sunspots coincide with strong electrical energy discharges from the sun.'
New York Times - July 12, 1976 - 'Climatologists Forecast Stormy Economic Future' - 'They believe that the earth's climate has moved into a cooling cycle, which means highly erratic weather for decades to come. And that, they say, has profound implications -- most of them bad -- for world food production, economic stability and social order. With the world's population now so high, the results in even minor year-to-year shifts in climate, could be catastrophic, they say"
'Skeptical Scientists': "Some scientists think all that is nonsense, mainly because climatologists can offer no scientific proof to back up their theories. If meteorologists, using sophisticated computers, can forecast weather only a day or two in advance, they ask, how can climatologists project climate years ahead? "It's interesting," said one skeptical scientist. "But some of their stuff is right out of fantasy land."
