Reduced Canadian wheat-growing potential after small drops in average temperatureThe global changes in average surface temperatures caused by the detonation of 100 Hiroshima-size weapons in the cities of India and Pakistan (50 weapons in each nation) would act to decrease the length of growing seasons in the Northern Hemisphere. In some places like Canada (see map below) the decreases in average temperature would have drastic effects upon the ability to grow the annual wheat crop. It is predicted that wheat exports would cease for three or more years; the global decreases in grain production would be severe and would likely lead to a global nuclear famine affecting hundreds of millions of already hungry people (see the article by Dr. Ira Helfand, "An Assessment of the Extent of Projected Global Famine Resulting from Limited, Regional Nuclear War") |
