Findings published in the journal Science in September, 2000, reinforced previous projections of increasingly destructive weather as climate change progresses.
That study follows two previous studies by Karl et al. which had established the connection between greenhouse warming and extreme weather events: "Trends in U.S. Climate during the Twentieth Century, Consequences, Spring, 1995, Vol. 1, No. 1, Thomas Karl et al. Also: "The Coming Climate," by Thomas R. Karl, Neville Nicholls and Jonathan Gregory, Scientific American, May, 1997.
A 2003 report by the World Water Council noted a steady increase in extreme weather events over the past 40 years -- with "major flood disasters" rising from 7 in the 1970s, to 18 in the 1980s to 26 in the 1990s.
