the graph shows far more dramatic warming and cooling in the past....much larger swings and almost straight up and down compared to the last 70 years, being born in 1951 i have been alive for most all of this time period and have not seen any dramatic warming at all, the largest single snowfall i have seen was in 1993 in pelham alabama.....biggest hurricane i experienced was Camille in 1969, biggest tornado outbreak i saw was in the early 70's that reached from bama way up into ohio
