Statistician Dr. Matt Briggs: Mooney shows a graph from their paper which is so silly that I refuse to picture it. He presents this graph, as do the authors, as if it were data. Which it is not. It is the output from a preposterously complex regression model (they “control” for 13 things!). Baseball fans: when do more beanballs, and hence more retaliations take place, in chilly April when the season has just begun and all are of good cheer, or late in hot August when tempers are up and when games start to feel a lot more crucial? Is the observed discrepancy therefore caused by climate change? Good grief, what a rotten paper, what a rotten theory.
'For 1 degree Celsius of warming, he'd expect about a 1 percent increase in interpersonal conflicts, a category that includes crimes like assault and robbery but also road rage and fights at baseball games.'
Mooney: 'For instance, one of the studies cited in the new meta-analysis is a 2011 paper published in Psychological Science (discussed in more depth here) showing a relationship between hot temperature days and the number of retaliatory beanballs thrown by Major League Baseball pitchers. The figure below shows their results in more detail:

The study's lead author Richard Larrick, a professor at Duke's Fuqua School of Business, explained in an e-mail the psychological research linking heat with shows of aggression.
Steve Milloy: Today’s elevation is not all that different from the low points of 1956 and 1965 (about 1,090 feet, shown in first graph), especially when you consider the increases in water use and human management of reservoir levels over time. No doubt that drought is affecting Lake Mead. But Western drought is natural (the region is a desert, after all), and Lake Mead was comparably low more than 100 ppm CO2 ago.
Bill Gates, Sir Richard Branson, Hollywood actors, venture capitalists — they’re all pushing lab-grown meat as the solution to world hunger and environmental sustainability, but scientists last week told a panel of experts they have serious concerns about the product’s safety.
