[Sust-mar] Loaded dice in the climate change casino

[Christopher Majka]

In June of this year over 4,000 daily high temperature records were  
broken in the United States. There were 159 record high temperatures  
for the month, and 42 all-time temperature highs. July has been even  
worse, the hottest month ever recorded in the United States since  
comprehensive weather recording began in 1895. July 2012 was the 328th  
consecutive month that global temperature exceeded the 20th century  
average. In Canada record-setting temperatures were recorded in July  
in many parts of the country. Is there a way we can determine if the  
extreme weather events we have been witnessing are indicative of a  
changing climate, or are we simply witnessing variable weather?

That's precisely what NASA's James Hansen and his colleagues have done  
in a strikingly elegant publication entitled Perception of climate  
change. Anyone who was alive and paying attention before 1981 can  
perceive the difference in climate that has occurred, and the analysis  
of large datasets of environmental information clearly and  
unequivocally confirm this change. To read more see my recent article
