DC’s cherry trees hit their official peak blossom date last Thursday, April 10th. That’s the latest in the year that the Capital has experienced peak blossoming in over two decades. (For you botanical historians, the last time that peak blossoming occurred this late or later was in 1993, when the event fell on April 11.)
In 2013 the blossoms were almost as late, hitting their peak on April 9. That was a pretty dramatic change from 2012, when the date fell on March 20. This change was most disconcerting to two groups: tourists trying to plan their trips to DC in advance, and global warming alarmists who trumpeted every earlier-than-expected cherry blossom as yet further proof of global warming. In fact, in a sizzling multi-part blog post series last year, followed by dozens of readers, we charted peak blossom dates against global warming data. We even had graphs. (See Adam Sandberg, Peak Bloom Is Here – DC’s Global Warming Canary Lands with Frost on its Feet, April 15, 2013.)
The past two years of unusually late blooms largely resulted from unusually cold weather. But unusually cold weather, in the view of White House Science Advisor John Holdren, is actually yet another sign of global warming. Holdren explained this to a freezing yet grateful nation in a two-minute video last January entitled The Polar Vortex Explained in 2 Minutes.
We suspect that Holdren’s agency, the Office of Science and Technology Policy (OSTP), may now have a second video in the works in this Blame-Everything-On-Global-Warming series. Perhaps they’ll call it Delayed Peak Blossoming Explained in 2 Minutes.
Regardless, we think Holdren’s first video is scientifically bogus, and so today we’re filing a formal Information Quality Act Correction Request with OSTP on that very issue. Who knows—we may yet nip this video series in the bud.
