Ed: Keith a couple question about that last chart; A. How is a Major Heat Wave event defined? B. What percentage of the globe is involved in each? C. And what human activity is supposedly responsible for the sharp inclines in 1970 1980 and 1995? or D. the plateaus starting 1975 and 1990? and the slight decline starting in 2000 and becoming more precipitously downward in 2005? BTW, while you criticize David's sources, why do you provide none for this chart?
