It has also been the coolest May here in Missouri (sniff, it reminded me of home, further North in Iowa...)
Anyway, here is a story related to me by the head of the computer department at the college I graduated from in 97.
"Back when I was a little boy of 5 (he was 56 at the time) my grandma had a bannana tree growing in her backyard. She lived in Louisiana. Before I turned 10, it got sick and died. She never was able to get another one to grow. Years later I asked a tropical plant specalist about that. He told me that it was too cold for banana trees to thrive in Lousiana." With that, he gave us our weather related assignments and dismissed the class.
Mine was to study the last one hundred years of High temperatures for the city where the college resided. Later I got to look at all the data.
Here is what I found.
The 1930's where the hottest, with a record temp of 114 Farenheit.
The 1920's were the coldest, with a record low of -26 Farenheit.
Even throwing out the above temps, those decades were the extremes for the 100 years of data.
After extensively looking at the data, I couldn't find a significant increase or decrease in the data (the variance was less than 1 degree).
So, given those results, I concluded that we were not in the middle of Global Warming, or Cooling. We haven't lived long enough to keep detailed records long enough to actually KNOW what we think we KNOW!
And to prove that point, look at this video...
