What does the “snowpocalypse” tell us about the likelihood of climate change? Nothing. As Roger Pielke Jr. explains:
What happens in the weather this week or next tells us absolutely nothing about the role of humans in influencing the climate system. It is unjustifiable to claim that a cold snap or heavy snow disproves or even casts doubts predictions of long-term climate change. It is equally unjustifiable to say that a cold snap or heavy snow in any way offers empirical support for predictions of long-term climate change. This goes for all weather events.
Further, it is professionally irresponsible for scientists to claim that some observed weather is “consistent with” long-term predictions of climate change. Any and all weather fits this criteria. Similarly, any and all weather is also “consistent with” failing predictions of long-term climate change. The “consistent with” canard is purposely misleading.
Knowledge of climate requires long-term records — on the time scale of a decade and longer. Don’t look to the weather to learn about climate, unless you have a long time to watch. Using the weather to score cheap political points in the climate debate appears to be a tactical area of agreement among those who otherwise disagree about climate change.
