How to misconstrue statistics in your favor: an example arguing against SB 32


statebystatechangeinco2emissionrateThis blog post on Fox & Hounds is an example of how to take statistics of one cause-and-effect relationship and misapply them to another situation. In this case, this graphic above shows how GHG emissions have dropped dramatically in states that used to burn coal to generate electricity, but now rely much more on natural gas. The decline in coal emissions has occurred over the last half-decade due to the fall in gas prices and the increased stringency in air quality regulations. But more importantly, those states had higher emissions that California to start with because they have been laggards in protecting their environments. The chart shows that these states are finally starting to catch up! If anything, this supports adopting SB 32 as a follow on to AB 32!

Yet the blog post misconstrues this situation to argue that it’s the “free market” that somehow is generating these greater reductions, implying that California and Mississippi had started from the same place–which of course if far from the truth. Yes, the market push from natural gas fracking explains some of this, but California was already so far ahead due to its own efforts that it has less room to improve.

Watch for these types of misrepresentations. Understand the initial premises by the authors. Ask hard questions before you accept their conclusions.
