Most forecasts of worldwide food production have been based on the assumption that global weather will stay “Many climatologists have associated this drought and other recent weather anomalies with a global cooling trend and changes in atmospheric circulation which, if prolonged, pose serious threats to major food-producing regions of the world”
“In India, for example, before the global warming trend of 1890-1940. severe drought struck about once every four years. With the warming, however, and more abundant monsoon rains, drought came only once every 18 years or so, greatly increasing India’s grain production.””Annual average temperatures over the Northern Hemisphere increased rather dramatically from about 1890 through 1940, but have been falling ever since. The total change has averaged about one-half degree Centigrade”
“a study of the past reveals that the Earth’s climate is highly variable—indeed, that variability is one of its fundamental characteristics”
