As received from Paul Tullis:
@Roger, Hansen is a physicist. “Climatologist” is more of a construct than a scientific discipline in itself; chemists, physicists, hyrdologists and more can all be qualified “climatologists.” As for Hansen, has been publishing peer-reviewed papers about Earth’s atmosphere for more than 40 years. Anyone qualified to speak knowledgeably about the climate would know that already.
@Johnnyreb, if you read Hansen’s paper or looked at any of the data on global temperature trends over the past century or two, it would be clear to you that the overwhelming trend is toward warmer temperatures. Extreme heat events such as those discussed by Hansen are more frequent, which causes the average to go up. There continue to be colder than average readings, but not enough of them, and not cold enough, to pull down the upward trend.
@Allen Brooks, regardless of what you may have to say about how the media reports temperature anomalies, if you would look at the entirety of temperature records, as Hansen has spent several years doing, you would see that the last decade was the hottest on record. This is just a pure, unassailable fact which is unaffected by perspective or opinion. To take just a small sampling, in the 1950′s the number of record temperatures in the US were composed of 52% highs and 48% lows. In the 2000s, it was 67% highs and 33% lows. In 2011, 73% of record temperatures were highs and 27% were lows. So far in 2012–probably skewed by the midwestern heat wave in March, and the fact that the year is barely 1/2 way done–it’s 90% highs and 10% lows. Still, the first 6 months of 2012 was the hottest first half-year on record. Again, these are unedited facts, not opinions, drawn from whole data sets and not samples.
Feel free to educate Paul on Hansen’s math.
