McKibben mockingly chastises well, the world, apparently. He directs his accusatory screed at “you” (as in, not him) for taking a hear-no-evil-see-no-evil position when it comes to potential connections between extreme weather and manmade climate change:
Caution: It is vitally important not to make connections. When you see pictures of rubble like this week’s shots from Joplin, Mo., you should not wonder: Is this somehow related to the tornado outbreak three weeks ago in Tuscaloosa, Ala., or the enormous outbreak a couple of weeks before that (which, together, comprised the most active April for tornadoes in U.S. history). No, that doesn’t mean a thing
It’s far smarter to repeat to yourself the comforting mantra that no single weather event can ever be directly tied to climate change.
When it comes to the media, at least, McKibben is off his rocker. Many journalists, at news outlets large and small, are asking questions about tornado-climate connections. They’re just not making the kind of overwrought assertions he seems to expect. In fact, they’re doing a fairly good job explaining the relationship between tornadoes and climate change, just as they did during the Russian heat wave and Pakistani floods last summer. Evidence abounds that journalists are getting better at covering the nuances involved in the relationships between climate change and various types of extreme weather.
Even Climate Progress’s Joseph Romm, a fierce critic who routinely flogs reporters for not explaining the threat of climate change more assertively, was fairly complimentary in a nice roundup; he even wrote that, “Today weatherman Al Roker appears to have gone beyond the data with his suggestion that “climate change” is bringing tornadoes to urban areas, although, admittedly, it is a brief clip and it’s not exactly clear what he is saying.” (Romm compliments McKibben’s op-ed, but they’re brothers-in-activism where climate is concerned, and well within their rights to express their opinions about the need to act.)
So what are the data and scientists saying? Let’s go back to coverage of the tornadoes that tore through the southeast and south in mid- to late April (see this 2011 tornado information fact sheet for details). Andrew Freedman quickly kicked out pieces for The Washington Post and Climate Central describing the immediate meteorological conditions (involving a southerly position of the of the jet stream and warm sea surface temperatures in the Gulf of Mexico, which abetted the convergence of a hot, humid air mass close to the ground and a cold, dry one higher up, which got all twisted up and formed funnel clouds—see this primer from the National Severe Storm Laboratory)—that created the tornadoes. He also dutifully explored the climate connection, explaining that, contrary to McKibben’s assertion in the Post:
Those of us who write about climate change are often accused of attempting to link every unusual weather event to climate change, as if increasing air and ocean temperatures can explain everything from hurricanes to snowstorms. In this case, with the second-deadliest tornado outbreak in US history, and with the most tornadoes for any April since records began in the early 1950s, it’s important to understand that the scientific evidence indicates that climate change probably played a very small role, if any, in stirring up this violent weather. This might disappoint some advocates who are already using this to highlight the risks of climate change-related extreme weather.
