NRP just ran a story on why Hurricane Patricia can’t be blamed on climate change—because it is just one event and single events can’t be definitively pinned on a trend.
Yeah, yeah, yeah, we’ve heard that before. And it’s entirely correct. Yes, this record-breaking storm is clearly related to a powerful El Niño, and no, we don’t know what the relationship between El Niño and climate change is. I’ve addressed all of that before, and probably so has every other climate change writer on the planet.
But that isn’t what people mean when they ask if this is climate change.
They’re not asking for a lecture about the difference between climate and weather or the definition of “trend” or any of that, they’re asking is climate change real? and is this the sort of thing we can expect more of? And the answer to both of those questions is unequivocally YES.
No, we don’t know if there has been a statistically significant change in hurricane behavior yet because we have no good baseline data to compare against. So while we can say Patricia was startling, we can’t really get a handle on how unusual the storm was. It had the highest winds of any storm measured, but we haven’t been measuring storms very well for very long. Yes, El Niño is a complicating factor. It’s important for anyone interested in seriously discussing climate change to understand these details so that we won’t be caught hanging when some climate denier twists them up for use as semi-true window-dressing for propaganda.
But all of that is a footnote to the story. The story is that unusually warm water produces unusually powerful hurricanes. Global warming includes the waters of the globe. This is what climate change looks like, among other things–monster hurricanes.
No single events will ever be pinnable to any trend because trends are only visible in multiple events. That isn’t going to change. It isn’t news. So, to NPR and every other journalist working on the topic, please stop misframing public questions in a way that allows you to answer “no” when the true answer to the real question is “yes.”
