This week, with great fanfare, NASA scientist James Hansen and associates released a paper "
The Perception of Climate Change" in the journal PNAS that claims that recent heat waves and droughts were caused by human-induced climate change. To quote their abstract:
" It follows that we can state, with a high degree of confidence, that extreme anomalies such as those in Texas and Oklahoma in 2011 and Moscow in 2010 were a consequence of global warming because their likelihood in the absence of global warming was exceedingly small."
This paper (found
here) has been quoted in hundreds, if not thousands, of media outlets and newspapers and has garnered the praise of many environmental advocacy groups.
The problem?
Their conclusions are demonstrably false and their characterization of the science and statistics are deceptive at best.
