And as we now know, such effects are not strictly local. As far back as the 1920s, British scientist Sir Gilbert Walker was already puzzling over the fact that monsoons in India had a direct effect on everything from droughts in Africa to the severity of winters in western Canada.
While the rest of the world has not seen the same increase in precipitation as the tropics, earlier computer models generated by the National Center for Atmospheric Research (NCAR) show that individual rainstorms worldwide will be heavier and more severe as global warming continues. This increase in “precipitation intensity” will be felt in the northern United States, northern Europe, and northern Asia, according to a study published in Geophysical Research Letters, a publication of the American Geophysical Union. All of these locales will experience “more intense precipitation for a given storm during this century,” researchers concluded.
