Bizarre North Pole temperatures cap off year of record-setting warmth
Hmmm.. if you look at their chart we were in a negative (cold) period, right up until 1940 or so, then a rapid rise in temperature changes. I wonder if anyone has ever looked at the fact that that is essentially the same window as high altitude jet airplane use? It is hard to believe we went on a CO2 making bonanza in the last 60 years or so...
