The Holdren 'cherry blossom vortex', Information Quality Act, and U.S. weather history

CEI is taking John Holdren to task over his “polar vortex” video.

In a post today at we have this:Post image for Will Cherry Blossoms Get Sucked into the Polar Vortex?

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.)

White House Science adviser John Holdren made some ridiculous and baseless claims about the “polar vortex” being tied to climate change in a hastily produced “never let a good crisis go to waste” style video on YouTube. Readers may recall our January 8th WUWT story:


The White House gets into the ‘polar vortex’ climate change blame business

So as the post at posits:

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.

I get word from our friends at the Competitive Enterprise Institute (CEI) that they are taking the claims made by Holdren in that January video to task. CEI is targeting two claims made in WH videos and blog posts:

“A growing body of evidence suggests that the kind of

extreme cold being experienced by much of the United States as we speak is a pattern that we can expect to see with increasing frequency as global warming continues.”

We also seek to correct a January 8th OSTP blog post by OSTP Senior Communications Advisor and Web Editor Becky Fried that features the above Polar Vortex Explained video.

We request a correction of its claim that “we also know that this week’s cold spell is of a type there’s reason to believe may become more frequent in a world that’s getting warmer, on average, because of greenhouse-gas pollution.”

Despite the widespread criticism that this claim has received, the video and a related claim are still up on OSTP’s website. The CEI petition uses OSTP’s own regulations (and the Information Quality Act) to request that this misinformation be corrected.

The late onset of cherry blossoms in DC made CEI wonder whether Holdren would soon be releasing a video attributing that to global warming as well.

CEI has a short blog post on this at

The blog post links to the OSTP correction request, which can also be found at:

We expect OSTP to shortly post the request on its website.

Just a reminder, we’ve experienced all this before:

In 1977, a nearly identical pattern set up with warmth in Alaska, drought in California, and cold in Florida. Arctic sea ice was near a peak at the time. (h/t Steve Goddard)

And then there’s the winter of 1963, the most “savage winter of the century” according to Life Magazine on February 8th, 1963:


And this illustration is from that Life Magazine article on page 33. Gee, that pattern looks familiar.

Those who do not study weather history are condemned to bloviate it as yet another effect of “global warming”.

“Global warming” was also responsible for a much-delayed maple sugar season here in NH. I believe it had a negative effect on overall production. The sap just didn’t seem to want to flow, and when it finally did, it was already getting too late. They’ve been warning about a negative effect on the maple industry due to “global warming” too, so I guess they were right.

Nice to see the h/t to Steve Goddard. His site is one of my favourites, as it so successfully counters the constant re-writing of climate history we see every day. Nice one, Steve!

As the last people who lived through the Dust Bowl pass on we can expect Alarmists to try to tell us current heat waves are “unprecedented.” Nothing we have experienced recently is even close to the heat of the Dust Bowl. However rather than learning from history Alarmists seek to “adjust” the historical record.
I think it is high time to take them to task for their “adjustments.” Is not that “falsifying public documents,” and a crime?

Slightly off topic but maybe every time a FOIA request is made, it should be a press release and/or forwarded to members of Congress followed by the results of the FOIA request? Maybe someone will start to ask “why”.
Back to this this story, is it just me or are “they” are beginning to acknowledge that nothing new is happening but “the nothing new” is now being caused by Man?

April 17, 2014 12:11 pm

Has anybody bothered to interrogate the cherry trees concerning how they decide upon which day they will blossom? That would seem to be the domain of botanists, who are also ‘scientists’ (IIRC).
It should come down to the air temperatures, pressures, moisture and precipitation, winds, and insolation between the thaw and blossoming.
I just hope they won’t require a FOIA request to access the meteorological history of Washington D.C.

April 17, 2014 12:16 pm

What about Canada in this discussion of winter? Ah yes, it is the tradition of policy types in DC to include or exclude Canada from the discussion in order to make a biased point for U.S. audiences. It just depends on whether it fits or not.–

April 17, 2014 12:22 pm

I’m so tired of reading about how the big ridge in the western U.S. and trough in the eastern U.S. this past year was “unprecedented”. People have such short memories. I was in California during the 1976-1977 drought (the year it snowed in Florida). Same kind of pattern. Big ridges in the west and troughs in the east are very common. Depending on what time of year they set up, they can easily become self-perpetuating. There’s nothing new about this.

Bruce Cobb, you write about maple syrup “They’ve been warning about a negative effect on the maple industry due to “global warming” too, so I guess they were right.”
I have kept a close watch on maple syrup production here in Lanark County, Ontario, and from what I can gather, it has been a good season. It may have been late, but when it came, production was good. I have not seen the final report. I suspect they have been so busy making syrup, that they have not had time to update their web site since 12th April

Question regarding plotting these dates based on calendar.
Since our calendar doesn’t match perfectly w/ respect to the Earth’s orbit of the sun, the seasons change at different dates. Specifically, the first day of spring officially a day later than a few decades ago.
Given this fact, wouldn’t it make more sense to plot when these annual events occur relative to the change in season? If so, then this year’s DC cherry blossoms may actually be tied for latest recorded.
Anyway, I had this thought a few weeks back when a post here discussed a site where they were a melting ice event had been recorded for the past ~150 years, and some catastrophists said the median date had shifted in that time frame.

April 17, 2014 12:34 pm

“A growing body of evidence suggests that the kind of
extreme cold being experienced by much of the United States as we speak is a pattern that we can expect to see with increasing frequency as global warming continues.”
That has to be one of the stupidest statements I have ever read in all my life.
“extreme cold … pattern … we can expect to see with increasing frequency as global warming continutes.” Eat your heart out The Onion.

If there was man-made global warming, the blossoms would be moving more into winter months towards January. However, we are is a solar sunspot minimum and winters are longer and will get even longer and nastier. Might lose the trees in the end but they are hardwoods. Wait and see.

For those that want to see those weather maps from that bitter cold Winter of 76/77, go to this link, to get reananalysis data/weather maps that go back to 1948. It’s actually a useful link to review previous extreme weather events and patterns.
For the CURRENT DATE, type in 1976 for the YEAR. For the MONTH: 12, for the day 25-(Christmas) then advance the day(+) one frame at a time and watch through the entire month of January 1977.
If you want to run a loop, then you must put in and END DATE also.
Note: Huge upper level ridge at high latitudes, Polar Vortex dropping very far south, similar to this past Winter.
I think going back a month earlier, to late November, allows you to see the evolution of this pattern while it was just starting to gain atmospheric traction. There was a severe drought in California during that Winter also and not by coincidence.
My point the last 4 months has been that it’s absurd to say that increasing CO2 caused this to happen in January 2014 because it matches up with a belief system but the same thing happening 37 years ago was from natural causes.
January 1977 is just one month to use as an example, there were many other instances of this happening in the past.
The same can be said about other weather extremes in the last decade……………give me the extreme event/pattern and most of the time, I can show you something similar or even more extreme happening in the past.

“…the last time that peak blossoming occurred this late or later was in 1993”

You mean that some things caused by global warming are not irreversible? It seems that life on this planet is highly adaptable to changes in the climate, and does so rather quickly. Who knew?
On the other hand, if global warming can cause both heat and cold, flooding and drought, ice loss and ice gain, then why can’t it cause trees to blossom both earlier and later in the year? Carbon dioxide is an intelligent but evil molecule that loves to play tricks on climate scientists. I can’t wait to see what new tricks it has up its sleeves. The entertainment is almost worth the cost of admission. Almost.

April 17, 2014 1:55 pm

Isn’t it a subjective decision as to when peak blossoms has occured. Maybe we should check the bias of whomever made that decision.

I just heard a discussion on CNN about how the Koch brothers are paying the cherry trees to bloom later and thus embarrassing all of the true scientists and their acolytes. SARC (Just in case.)

April 17, 2014 3:13 pm

For months I have been comparing this Winter to that of 1977, which I remember vividly as a high school classmate of Bill McKibben, in Lexington, MA. That season was capped with 10″ of very heavy, wet snow on May 9-10, when the leaves were already out on the trees. The extra load of the snow on leaves brought down limbs and trees in large numbers, leaving thousands without power for nearly a week.

April 17, 2014 3:36 pm

Yeah, so what? This also out of DC… Read it a weep. As far as the executive branch is concerned Climate Change is a huge problem now. They have no interest in cherry blossoms. They “know” that “carbon pollution” is a toxin like mercury and arsenic and say as much. Could they be thinking of CO. Can’t be CO2, it’s not a poison and not toxic. Wonder if B.O. has ever heard of WUWT?

April 17, 2014 3:41 pm

I still find it shocking that after telling us that the weather is not the same as the climate – they are now doing the same. It is a sign of desperations.
They told us global warming would lead to warmer winters, early springs, cherry ‘picking’ blossom bloom etc. Now they insist that ONE COLD OR HOT WINTER is positive proof of global warming OR climate change OR disruptive, naughty, badly behaved weather fronts. This is getting silly now.

I checked that LIFE magazine from 1963. The article ends with this statement: “But last week at least one U.S. Weather Bureau spokesman dropped a chilling thought. The whole world is generally beginning to get a little bit colder, he said, and this winter might be the frigid forebear of worse ones to come.” Plus ça change…

Japanese cherry blossom blooms were confused by climate chage caused by something or other.

Clarifying springtime temperature reconstructions of the medieval period by gap-filling the cherry blossom phenological data series at Kyoto, Japan
……………..The reconstructed tenth century March mean temperatures were around 7°C, indicating warmer conditions than at present. Temperatures then fell until the 1180s, recovered gradually until the 1310s, and then declined again in the mid-fourteenth century.

April 17, 2014 4:34 pm

The question that needs to be asked is:
Why didn’t the warmist climate modelers warn us?
They can see the future! I hear the regional climate forecasts are really good now!
Forecasting a Polar Vortex in 2014 should be much easier than forecasting the climate in 2100; due to inevitable error accumulation in an iterative model.
It’s quite maddening that the corrupt press lets them get away with their preposterous pseudoscience for so long now.

While the southern part of Japan is covered with cherry blossoms, Kushiro, a city to the southeast of Hokkaido, is still boasting a blanket of pure white snow.

All this in one relatively small country. Whoever choses to cherry pick cherry blossom bloom dates to show global warming is mad. I have picked the best cherries by using ‘reductio ad absurdum’.

April 17, 2014 4:43 pm

Funny that when cherry trees bloomed later in the spring a few years ago some claimed that was proof of global warming, yet deny that a global MWP was confirmed by studies of historical cherry blossoming dates in Japan:
Studies of cherry blooming dates in Japan also confirm cooling occurred there during LIA.

Interesting because we are still experiencing summer weather patterns in Western Australia.

April 17, 2014 4:49 pm

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.

Plus the Great Lakes freezing late, Arctic sea ice extent Sept 2013 growth on 2012, general colder winters in the NH, Antarctica sea ice extent not normal, global sea ice kinda normal etc. This is climate change or the weather. I don’t really care as long as Warmists are forced to face their demons.
I find it so odd that all this is happening just after the HOTTEST DECADE ON THE ‘RECORD’. Mmmmm.

Medieval Climatic Optimum
Michael E Mann – University of Virginia, Charlottesville, VA, USA
It is evident that Europe experienced, on the whole, relatively mild climate conditions during the earliest centuries of the second millennium (i.e., the early Medieval period). Agriculture was possible at higher latitudes (and higher elevations in the mountains) than is currently possible in many regions, and there are numerous anecdotal reports of especially bountiful harvests (e.g., documented yields of grain) throughout Europe during this interval of time. Grapes were grown in England several hundred kilometers north of their current limits of growth, and subtropical flora such as fig trees and olive trees grew in regions of Europe (northern Italy and parts of Germany) well north of their current range. Geological evidence indicates that mountain glaciers throughout Europe retreated substantially at this time, relative to the glacial advances of later centuries (Grove and Switsur, 1994). A host of historical documentary proxy information such as records of frost dates, freezing of water bodies, duration of snowcover, and phenological evidence (e.g., the dates of flowering of plants) indicates that severe winters were less frequent and less extreme at times during the period from about 900 – 1300 AD in central Europe……………………
Some of the most dramatic evidence for Medieval warmth has been argued to come from Iceland and Greenland (see Ogilvie, 1991). In Greenland, the Norse settlers, arriving around AD 1000, maintained a settlement, raising dairy cattle and sheep. Greenland existed, in effect, as a thriving European colony for several centuries. While a deteriorating climate and the onset of the Little Ice Age are broadly blamed for the demise of these settlements around AD 1400,

Jimbo, your references to Cherry blossoming dates in Japan posted while I was writing my post, so mine were not intended as thunder theft nor reply to your posts. I do think, though that I should note that the studies by Aono used blooming dates from many, many years, garnered mainly from the dates of the annual cherry blossom festival in Tokyo, Japan.

Global warming used to be about global SURFACE temperature warming. It was easy to understand.
Global Warming became Climate Change TM.
Climate Change became Climate Disruption.
Climate Change became weired weather.
Climate Change became cold, warm or average weather events.
Today Climate Change means anything they want it to mean. This is no longer science but a cult.

Warmists cherry pick to death and it is ironic that they used to pick the cherry blossom bloom dates to prove their weak case. I too can cherry pick cold events to ‘disprove’ their hypothesis.

Almost one month into spring, and the U.S. Coast Guard is still breaking up ice around the Great Lakes.
According to the National Oceanic and Atmospheric Administration, more than 64 percent of Lake Superior was covered in ice as of Wednesday. Lake Michigan was 21 percent covered, Lake Huron was 31 percent covered, Lake Erie was 14 percent covered, and Lake Ontario was 2 percent covered. The entire Great Lakes system was 37 percent covered in ice…
The ice was preventing the delivery of coal to the area, needed to power local mining operations…
Ice in Marquette harbor was reported to be up to 24 inches thick.

17 April: North-West Indiana Times: Deborah Laverty: Students hear two sides of global warming debate
VALPARAISO | Hebron High School junior Kasie Sass said Thursday’s World Affairs Conference held at Ivy Tech Community College was the first time she had heard both sides of the heated global warming issue.
“It was pretty interesting and I definitely heard a different perspective. I am so used to hearing all the propaganda from the other side,” Sass said.
Chesterton High School junior Alyssa Bowker agreed.
“I learned a lot of facts that I’d never been told,” she said.
Sass and Bowker were among about 150 area students who took part in the Rotary District 6540 sponsored conference to discuss the Storm Over Climate Change.
The two keynote speakers, Steve Goreham and Jorge Ortiz, gave opposing sides of the issue at a gathering of other students in Manchester University in North Manchester…
Goreham, a policy adviser to the conservative Chicago-based the Heartland Institute, said those who believe in the claims of looming global warming are all wet.
Even on the heels of what he termed a “good old-fashioned northern winter,” some people are still saying the snow is disappearing and will stop unless global warming is stopped, Goreham said…
Ortiz, regional director for U.S. Senator Joe Donnelly, D-Ind., spoke on the senator’s behalf.
In his speech, Ortiz provided definition of climate change and updates on how it is being handled in this country and throughout the world.
Ortiz said the Environmental Protection Agency defines climate change as temperature changes that have increased by 1.4 degrees.
***”More and more agree that the temperature is rising but there is no consensus on why,” Ortiz said.

When the US had the polar vortex in winter 1963 we in the UK had our worse winter of any since 1947 in terms of ice, snow and cold. This winter when the US had the polar vortex we had a relatively warm and extremely wet winter. If the “highly sophisticated” medium range weather forecasting we have today was available in 1962 would it have predicted the US and UK winters correctly then and now? I think not.
Will medium range weather forecasting ever become good enough to make a useful distinction in the 2 scenarios of 1963 and 2014 in the UK? I also think not.

No – that was why Julius Caesar invented leap years (and Pope Gregory refined the system in 1582). The beginning of spring is always within the same (roughly) 18-hour period
