It was cold last week, wasn’t it? And it’s gonna be a cold winter.
How do we know?
Well, we don’t know, in the sense of being certain beyond a scintilla of doubt. But we do have some pretty good info telling us it might be a good idea to make sure we have enough long-johns and sweaters for the coming months.
And no, this info does not come from the Farmers Almanac, which claims to be “known for its traditionally 80 percent accurate forecasts,” but does not reveal by whom it is so known.
Kind of fun, the Farmer’s Almanac, but even if it no longer uses the “pig spleen method” or the “ol’ goose bone method” of weather forecasting, its reliance on “a secret formula that was devised by (founder) Robert B. Thomas” in 1872 does not inspire confidence in its results, especially when its proprietors sum up their approach by proclaiming that they “believe that nothing in the universe happens haphazardly.”
Oh, sure it does.
Instead of secret formulas, this projection that a cold winter lies ahead comes from scientists both public and private, who project colder than usual weather for the entire Northeast, and who, being scientists, acknowledge a certain margin of error in their projections.
As AccuWeather.com’s Chief Meteorologist and Expert Long Range Forecaster (yes, all those capital letters are AccuWeather’s idea) Joe Bastardi, put it, this winter’s likely “fading El Niño results in the stormiest and coldest pattern in recent years.”
But don’t panic. First of all, the National Weather Service agrees about the cold, but not the storms. And even Bastardi thinks that most of those storms will be south of Boston, and therefore safely south of Vermont. Boston and northward, he said, should see “normal snowfall with temperatures slightly below normal this winter.”
That possible “fading El Nino” will make it colder because the stronger and longer-lasting the El Nino (“A change in the surface water temperature in the Pacific Ocean that produces a warm current”), the warmer it is all over the United States, even this far from the Pacific.
This far, though, the meteorological impact will be small, hence the projection of temperatures “slightly below normal.” No one is predicting a deep freeze.
The economic and political impacts are harder to predict. If winter precipitation is normal, the snow-plowing budgets should follow suit. On the other hand, colder weather is likely to prompt Vermonters to spend more money and/or split more logs to heat their homes. (Of course, the more logs one splits, the less fuel one needs, the act of splitting itself providing ample warmth).
The political prediction should be more qualified than the long-range weather forecast, but a cold winter is likely to energize the global warming denier crowd, even though a cold winter provides exactly zero evidence to refute the scientific consensus that human activity is warming the earth.
Alas, evidence or lack thereof seems no hindrance to the climate change deniers, who are inspired by impulses from within, not data from without. Consider the blogger calling himself “NORTHERNVT” who complained in Sunday’s Burlington Free Press that “global warming is a load of crappp,” his “evidence’ being that it was chilly out. This is not an argument based on evidence; it is a blurt based on resentment, specifically, in this case, of Al Gore and his movie An Inconvenient Truth.
Not that Gore et al don’t sometimes overstate their case. In the movie (reportedly; the News Guy did not see it) Gore makes much of the melting of the “Snows of Kilimanjaro,” famous because Ernest Hemingway made those words the title of one of his brilliant short stories.
The snow and ice on the mountain are melting, but not, according to some scientists, because of global warming. Significantly, though, these very scientists think the ice atop many other African mountains is melting because of global warming.
Aside from the occasional bleat, global warming denial has been an insignificant force in Vermont, where no major elected official seems to deny the overwhelming evidence of anthropogenic (the fancy term for “human-caused”) warming. The only deniers hereabouts are a commentator or two whom few take seriously to begin with.
But a bit of a counter-attack — on the face of it a most ineffectual counter-attack — is coming nationally, so if this winter is colder than usual, one might expect a little more noise from the local deniers.
The counter-attack comes in an about-to-be-published book by Steven Levitt and Stephen Dubner, a sequel to their much praised best-seller, Freakonomics. The sequel is Superfreakonomics: Global Cooling, Patriotic Prostitutes, and Why Suicide Bombers Should Purchase Life Insurance (Harperluxe), which is a funny title, but the book seems to say (according to several discussions on line) that the earth has actually been getting cooler “over the past several years.”
Uhhh, no. The last two months were the second hottest August and Septembers on record. This year is likely to be the fifth hottest year on record, meaning that all ten hottest years will have occurred in the past 15 years.
There are more than enough other outrageous errors in the climate change chapter to prevent any reasonable person from taking it seriously.
Which is not to say that reasonable people shouldn’t keep an open mind. Like all other scientific conclusions, the anthropogenic global warming consensus is tentative. The first time a dissenter puts his or her doubts into scientific form, submits the product to the climatologists (peer review), and the climatologists can’t immediately dismiss it, then the rest of us will have to go back to square one.
So far, no such paper has been submitted.
