How Long Will the Cold-Snap Last?

The following sample of stories from the past year show that much of the world has been experiencing a cold spell:

  • Across the South, Midwest, and Eastern seaboard [of the United States], a stubborn “arctic outbreak," tacked onto an already cold return to work for many Americans, augurs what meteorologist at are calling “the coldest winter in many people’s memory.”

Highs Versus Lows

On the other hand, the National Center for Atmospheric Research in Boulder argues that - while there have been numerous record lows - there have been more record highs than lows in the past decade, and that the ratio of record highs to record lows has actually increased. See this, this, this and this.

Short-Term Aberration, Or Change in Climate Trend?

Are the current spate of record lows just a short-term aberration, or a change in climate trends?

Those defending the C02 global warming theory argue, of course, that short-term weather fluctuations are irrelevant, and that the long-term trend is runaway warming.

But on Tuesday, the New York Times' Andrew Revkin presented a less simplistic yet still mainstream view of the issue:

A big driver of the outbreaks of record cold and snow in many spots around the Northern Hemisphere is ... the Arctic Oscillation, a pattern of atmospheric pressure that has two phases, positive and negative (somewhat like the more familiar cycle of El Niño and La Niña in the Pacific). A strong negative or positive condition can powerfully influence weather around the northern half of the globe and the behavior of sea ice on the Arctic Ocean.

The blue dot shows an extraordinary negative plunge of the index in December, taking it below any such reading since at least 1950 ...

The head of the Beijing Meteorological Bureau asserted that global warming was behind unusual atmospheric patterns (a heap of climate scientists I queried saw no such link). Blogs of those variously called climate realists/skeptics/deniers are hammering on the chilly conditions, presumably in hopes of fending off a new push to close out the climate bill in the Senate.

John Michael Wallace of the University of Washington, one of the climate scientists who first identified the seesaw patterns of pressure around the North Pole and northern mid-latitudes, told me that the steep drop at the moment is likely to be transitory rather than a sign of a new trend in the Northern Hemisphere pressure cycle.

Overall, federal forecasters have said that the warming influence of a persistent El Niño warming of the tropical Pacific Ocean is likely to be a bigger driver of conditions through the full course of this winter ...

Michelle L’Heureux, a meteorologist at the National Oceanic and Atmospheric Administration’s Climate Prediction Center, told me there’s simply no explanation for what drives such extremes in the Arctic Oscillation, which she described as both a potent driver of northern latitude conditions and one of the least predictable, and understood, patterns in the atmosphere.

In other words, the mainstream view is that the Arctic Oscillation is driving the cold whether, no one knows what causes the Arctic Oscillation to switch on or off, but it will likely be short-term.

Top Climate Scientists Disagree

One of the leading climate modelers in the world - Professor Mojib Latif of Germany's Leibniz Institute - disagrees. Professor Latif is the recipient of several international climate-study prizes and a lead author for the United Nations Intergovernmental Panel on Climate Change (IPCC) who has contributed significantly to the IPCC's last two five-year reports that have stated unequivocally that man-made greenhouse emissions are causing the planet to warm dangerously.

Specifically, Latif thinks that the cold temperatures could last a decade or two.

In case you didn't catch it, Latif made a presentation in September which addressed the cooling trend:

Yet last week in Geneva, at the UN's World Climate Conference--an annual gathering of the so-called "scientific consensus" on man-made climate change --Latif conceded the Earth has not warmed for nearly a decade and that we are likely entering "one or even two decades during which temperatures cool."

The global warming theory has been based all along on the idea that the Atlantic and Pacific Oceans would absorb much of the greenhouse warming caused by a rise in man-made carbon dioxide, then they would let off that heat and warm the atmosphere and the land.

But as Latif pointed out, the Atlantic, and particularly the North Atlantic, has been cooling instead. And it looks set to continue a cooling phase for 10 to 20 more years.

"How much?" he wondered before the assembled delegates. "The jury is still out."

And see this.

Latif believes that after several decades of cooling, then global warming will kick in.

Other climate scientists predict longer periods of cooling. For example, Professor Don Easterbrook from Western Washington University says:

The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us of about 30 years of global cooling.
And professor Qing-Bin Lu University of Waterloo argues in a peer-reviewed paper that we will have 50 years of cooling.

Who Is Right?

So who's right?

I have no idea. But - for now - I'm freezing my tail off.

Note: New evidence shows that ice ages can start faster than scientists previously believed - perhaps in a matter of months. See this and this.

That raises an interesting question: even if we are projected to have C02-induced global warming in the future, will the current cold snap - if it continues for another year or so - change the long-term climate trend?


  1. It's nice and toasty here in Phoenix. Low to mid 70's last week, and the same all next week. Man has no business living where water freezes. Global warming, global ice age, Phoenix is looking pretty good.

  2. All you need to do to get a handle on this is go back 50 years & read any of the science journals. See all the quaint things they believed to be scientific. The best way to understand new science is go back & read old science. It's shot full of junk. Speculation. Wild guesses. Always has been. Always will be. Always dressed up as Ultimate Truth.

    The earth gets warmer sometimes, it gets cooler sometimes. The process is not well-understood, but long-term historical records, documenting temperature swings, are clear. Two years ago we had a global warming bandwagon. Now a global cooling bandwagon is starting to take shape.

    The term, "ice age" is a misnomer. More than 50 years ago, the wrong man demonstrated that "ice ages", ie, times when massive sheets of ice spread out from the polar regions over the lower land masses, to be an impossibility. How would the ice get to, say, New York? There would first have to be a lot of heat to evaporate a lot of water so that it could be moved north where it could fall from the sky & freeze. But how could it stay frozen if heat was required to move ever more of it? In fact, the greatest snowfalls come when warm moist air meets up with cold dry air & snowfall is the result. When all the air is cold, there is no snow. If there is no snow, there is no ice & spring will eventually come. Warm moist air will sweep over the land, rain will fall, and life will return.

    While Science may be a philosophical ideal, the science we actually have, dominated by petty egos, is increasingly a false god. We should realize that ideals are unrealistic & unobtainable, stop being bullied & instead, pick & choose among competing dogmas. But, I hear you cry, whatever would we do without the bedrock of Scientific Truth?

    Well, for one thing, maybe we would start to think for ourselves again. If blogs can blow mainstream media out of the water, blogs can blow down fake science, too. There's nothing special about Ph.D's.

  3. This is my theory. People who don't believe in the power of collective consciousness will, of course, not believe it. One has to believe in the metaphysical power of will in "mind over matter". My perspective is that God gave Adam rule over all the earth in dominion and power. So, my perspective is that the power of human will is incredible in truly "controlling" the earth more than what we realize. The power of "group will" is very much akin to the power of prayer - in a different form of will.

    So.... many people today believe global warming is real - that they are willing cooler temperatures. Just like a person can recover inexplicably from an illness by force of will and "mind over matter", so too, I believe there is a power in group collective consciousness all willing away the perceived threat of "global warming" (which was a hoax anyway).

    I believe people are willing the earth to cool - and they should be careful what they wish for.

    Just a point of view - and no one who doesn't believe in the power of collective consciousness really needs to debate it. I won't be moved by them - nor will they by me.

  4. There may have been many lows, but there have been many more highs as shown on the graph here from the National Center for Atmospheric Research.

  5. There's "Global Warming"! Today 9th January in Melbourne Australia temp max 34degres centigrade!! In January!! So there's a "Global Warming"!!!!

  6. I think the hype is ridiculous. I grew up in the midwest, and I recall winters such as this and worst in the 70's and early 80's.

  7. Haven't followed all your links, but will note that the NYT article about freezing canals in the Netherlands dates to January 2009, when the canals did indeed freeze for the first time in 12 years. It does not refer to the current cold snap.

  8. Global warming or not the Sun determines that totally. The CO2 has nothing to do with this issue. Here is the proof with math and graph. The result is not the reason for the result except in economics:

  9. 34 celsius in Melbourne "in January!!!". It is summer in the southern hemisphere. Jan is often the warmest month.

  10. Everyone has their favorite way of using the internet. Many of us search to find what we want, click in to a specific website, read what’s available and click out. That’s not necessarily a bad thing because it’s efficient. We learn to tune out things we don’t need and go straight for what’s essential.
