A frigid blast of Arctic air will bring some of the coldest late February temperatures seen in decades to the eastern 2/3 of the U.S. this week, with temperatures 15 - 30° below normal commonplace. The cold air isn't going anywhere fast, and will stick around through early next week. The cold blast is due to an extreme jet stream pattern we have seen before this winter--a sharp ridge of high pressure over California, and a large trough of low pressure over Eastern North America. This upper air pattern was described by the National Weather Service in Buffalo, New York on Tuesday as one that occurs less than once every 30 years in late February. The intense cold is already affecting the Upper Midwest this Wednesday morning. My vote for worst winter weather of the day goes to Central Minnesota at Alexandria, where a temperature of -8°F this morning combined with winds of 14 mph to make a wind chill of -28°. The winds are expected to increase to 25 - 30 mph Wednesday afternoon with higher gusts, creating blizzard conditions. In Chicago, the intense cold is expected to put the December - February average temperature for this winter below 19°, making the winter of 2013 - 2014 the 3rd coldest winter in the Windy City's history. Only the winters of 1978 - 1979 and 1903 - 1904 were colder.

Ice cover on North America’s Great Lakes reached 88 percent in mid-February 2014—levels not observed since 1994. The average maximum ice extent since 1973 is just over 50 percent. It has surpassed 80 percent just five times in four decades. The lowest average ice extent occurred in 2002, when only 9.5 percent of the lakes froze. Image credit: NASA Earth Observatory.

Rain coming to California
Unlike previous versions of this extreme jet stream pattern, though, the ridge over the Western U.S. will not be very persistent. The ridge of high pressure over California, which brought numerous record high temperatures for the date on Tuesday, will get broken down by a weak low pressure system on Wednesday and Thursday. On Friday and Saturday, a more intense storm system will smash through the ridge, bringing moderate to heavy rain to much of drought-parched California. This storm will then track eastwards, potentially bringing a major snowstorm and destructive ice storm on Monday to Illinois, Kentucky, Indiana, Ohio, West Virginia, and portions of the Mid-Atlantic and Northeast U.S.

A negative phase of the Arctic Oscillation (AO) created a sharp kink in the jet stream (Figure 3), which allowed cold air to spill southwards out of the Arctic over the Eastern U.S. Compensating warm air flowed northwards into the Arctic underneath ridges of high pressure over Alaska and Europe.

Wanted: professionals willing to speak about climate change to local groups
If you are a professional or graduate student with a strong background in climate science, the world needs you to reach out to local audiences at schools, retirement homes, the Chamber of Commerce, etc., and share your expertise. A new initiative by the University Corporation for Atmospheric Research (UCAR) and the United Nations Foundation called climatevoices.org is launching a Science Speakers Network this spring, with the goal of bringing scientists and their local communities together for real dialogue on climate science that speaks to citizens’ current and future well-being and responsibility as members of a community and democracy. Materials for context-setting presentations will be offered as will coaching regarding how to begin conversations about climate change with fellow citizens. If you are interested in volunteering for this network, please go to climatevoices.org and create a profile.  Profiles will “go public” when the full web site is launched in April. Once you create a profile, you will be kept up to date on Climate Voices progress including construction of the full web site, availability of presentation materials, webinar coaching, and plans for project launch. For any questions, please contact: Cindy Schmidt (UCAR), cschmidt@ucar.edu. I have my own set of slides I use for such talks that anyone is welcome to borrow from, available at http://www.wunderground.com/hurricane/2013/climatetalk.ppt.

In the long run, the Earth's water and most of its atmosphere will eventually escape into space. During its life in the main sequence, the Sun is becoming more luminous (about 10% every 1 billion years) and its surface temperature is slowly rising. The Sun used to be fainter in its early past. The increase in solar temperatures is such that in about another billion years the Earth's atmosphere will no longer be cold enough to freeze water vapour at high altitudes.[citation needed] Water molecules will then be able to reach the top of the atmosphere, which will lead to the Earth's water escaping into space, rendering the planet inhospitable to all known terrestrial life.[115][116] The Earth is not expected to survive the Sun's transition into a red giant. At its largest, the Sun will have a maximum radius beyond the Earth's current orbit, 1 AU (1.5×1011 m), 250 times the present radius of the Sun.[115] By the time the Sun has entered the asymptotic red giant branch, the orbits of the planets will have drifted outwards due to a loss of roughly 30% of the Sun's present mass. Most of this mass will be lost as the solar wind increases. Also, tidal acceleration will help boost the Earth to a higher orbit (similar to what the Earth does to the moon). If it were only for this, Earth would probably remain outside the Sun. However, current research suggests that after the Sun becomes a red giant, Earth will be pulled in owing to tidal deceleration.[1

What's most amazing is that, once it was a settled science fact, the earth as we know it would end in some time span measured in billions of years, that one more dime was spent on this when we have some pretty pressing issue that aren't that far away.

"Throughout the history of the Earth, the planet's climate has been fluctuating between two dominant states: the greenhouse earth and the icehouse earth...."

"With so much attention focused on global warming, this chilly prospect has been all but forgotten. Given how catastrophic another ice age could be, one might be tempted to ask whether a human-caused increase in atmospheric and ocean temperatures will actually be a boon."

Actually, the cycle of Ice Ages hasn't been forgotten, but has been the subject of considerable effort to define past climate. It appears that there was a fundamental change in the Earth's climate around 3.0 to 3.3 million years ago, with the Earth entering a repeated cycle of glacier growth over some 100k years, then melt during short Interglacial periods of perhaps 10k years. That cycle may have been the result of the closure of the Isthmus of Panama, which blocked surface flow between the Atlantic and the Pacific, which then caused the Atlantic to become more saline as moisture was lifted over the land between the two oceans.

Human civilization developed during the present warm period of about 10k years as the result of the invention of agriculture. Therein lies the problem of AGW, which is, our agricultural production is tied to the climate we have experienced and some projected changes will reduce agricultural output just as the population grows from 7 Billion to around 10 Billion by the end of this century.

One of these problems might be a reduction in the thermohaline circulation in the North Atlantic, which moves warm waters from the sub polar gyre to higher latitudes and thus influences weather over the higher latitudes around the North Atlantic. Note that this flow is not the Gulf Stream as often referred to in the media, but a northward branch of a fraction of the larger flow. A recent paper presents measurements which indicate that this process is exhibiting a slowing over the brief period of measurements, which could well be influencing present weather. And, this is just beginning if the climate scientists have it right...

When you look upon a global warming denialist, you are not seeing a person who is deluded, wrong, misinformed, or misguided. You are seeing a person who is intent on killing your grandchildren.

Talk about a grumpy old man! Maybe he was a little short on caffeine when he wrote this. I sure hope he realizes that how you talk on the internet is different than what you say to people face to face. He is a good example of one of the perils of unedited open source blogging.

...I saw no predictions, not even this fall, consistent with this [cold US] outcome.
But there were many such predictions, including right here in this forum. Perhaps not specifics: "February will be one of the coldest on record for Chicago". But some spoke of the possibility that Dr. Jennifer Francis' theory of wonky jet stream behavior due to the relatively sudden disappearance of the Arctic ice might possibly induce more-or-less persistent cold in some NH locations, and more-or-less persistent warmth in others.

That, of course, is precisely what has happened.

Why is Anthropogenic Global Warming Denialism Important?

Posted by Greg Laden on June 28, 2011

And what do we do about it?


Global warming is for real, and it is important. Just as important is the fact that global warming is largely anthropogenic. Global warming is important because conditions for life on the planet are changing due to warming as well as other changes caused by the release of fossil carbon into the atmosphere, in ways that will have, on balance, negative impacts; That it is anthropogenic is important because this means we have identified a cause of an important negative effect and thus could potentially curtail it. The anthropogenic nature of global warming is also important for another reason: It provides a test case. Can humanity handle a problem of this magnitude, that it has created for itself, with sufficient speed to curtail the worse consequences? Or not?

It has been said that global warming is a mixed bag: For some it will be bad, for others it will be good. This is a myth. Global warming is on balance bad, and it is mostly bad. Never mind the extra CO2 in the atmosphere that plants like, and which would increase agricultural productivity. Plants do not produce more tissue, fruit, grain, or what have you in direct proportion to the CO2 in the atmosphere. A little, yes, but after a small increase in productivity more CO2 does not increase productivity. The small amount of productivity is offset by the negative consequences of global warming.

It may be that the most significant impact of “global warming” will actually be not in atmospheric temperature change, but rather, in the change of ocean chemistry caused by absorption of extra CO2. If ocean chemistry changes in a way that some models predict, it will become difficult for several kinds of small marine organisms to build their shells. Many of these organisms reside at or near the base of the marine food chain. Some also serve, collectively, as one of the primary means by which atmospheric CO2 is broken down to produce atmospheric oxygen. Collectively, they are one (and an important one) of several “lungs of the, planet.” In the worse case, which may or may not happen, oxygen may become noticeably depleted in our atmosphere, and food supplies may be negativelhy affected.

The situation will probably eventually resolve itself. A widespread oxygen-breathing organism causes the oxygen-producing system to fail and disrupts its own food chain. The oxygen-breathing organism then goes extinct (taking numerous other species with it). Eventually, oxygen-producing systems re-develop, food chains adjust, and something like present-day conditions return, and since the oxygen-breathing organism that caused the problem to begin with has gone extinct, things would be back to something that passes for normal for a while.

If you are an anthropogenic global warming denialist, you can count yourself as partly responsible for such a calamity. You probably won’t live to see the worst consequences because you are old (most AGW denialists are grumpy old men). You may want to write a letter to your grandchildren, who will suffer these consequences, explaining your role in creating their misery. Just sayin’

What does AGW denialism look like?

It looks like a lot of things.

It looks like anonymous Internet cranks shouting at other people for not being real scientists.

It looks like people shouting about alarmism.

It looks like faux journalists seeking a “balanced view” that gives “both sides” of “the debate.”

It looks like web sites pretending to be valid science-oriented resources faking data and making stuff up, and Internet trolls dropping links to those sites wherever possible to (mis)direct people to them.

How do we address it?

Call them on it, every time they open their mouths. Demand explanations for their motives (which is something to think about, by the way). If you are a blogger and they comment on your blog, you need not be intimidated by screechy references to the “First Amendment” … just delete their blaterhing or change their links to point to the web site of the Spam Museum, a major Minnesota Attraction. Or whatever.

When you have friends or colleagues who seem to show leanings towards AGW denialism, show them clearly that you do not take them seriously, indicate subtly that their credibility is at stake, politely give them links to sites like Real Climate where actual climate scientists talk about actual climate science. Do not vote for, and always vote against, politicians who are denialists. Yes, yes, I’m suggesting that Anthropogenic Climate Change is a “litmus test” issue, because it is. And the litmus test is not only a political one … it is also a test of ocean acidity, which has increased by an average of 30% with the release of fossil carbon to date, and which is expected to reach 150% by 2100, which, in turn, is probably beyond one or more thresholds of disaster.

When you look upon a global warming denialist, you are not seeing a person who is deluded, wrong, misinformed, or misguided. You are seeing a person who is intent on killing your grandchildren. You may want to treat them politely, you may want to be a dick to them. Do whatever works. But don’t let them think for a second that you do not know what the consequences of their actions are. Don’t let them get away with it.

"The lobby opposing climate-change science is fundamentally political. A political tactic is the deliberate, distorted misrepresentation of information and its implications. It is effectively disruptive. It is not a threat to the science-based knowledge we have of our climate. It is, however, a much deeper threat to us all."

The CO2 we have emitted into the atmosphere will and has overwhelmed any Natural forcing toward a cooler climate, where we were headed until we began terra forming a Warmer globe.

Which we have done very well the last 150 odd years.

So hang on, itsa gonna get much warmer downstream in time.

from an MIT review..................Global warming is an inescapable issue for our age. But 180 years ago, most scientists believed that Earth had been steadily cooling since it was formed. When Louis Agassiz presented the concept of a Great Ice Age to the Swiss Society of Natural Sciences in 1837, his suggestion that the planet had turned colder and then warmed up again was met with skepticism and even hostility, triggering years of fierce scientific debate before the idea was accepted.

Exactly why our planet occasionally cools down has taken more than a century to work out. Now we know that cyclic gravitational tugs from Jupiter and Saturn periodically elongate Earth’s orbit, and this effect combines from time to time with slow changes in the direction and degree of Earth’s tilt that are caused by the gravity of our large moon. Consequently, summer sunlight around the poles is reduced, and high-­latitude regions such as Alaska, northern Canada, and Siberia turn cold enough to preserve snow year-round. This constant snow cover reflects a great deal of sunlight, cooling things down even more, and a new ice age begins. Naturally, this process does not occur with anything like the speed portrayed in the movie The Day After Tomorrow, but geological and other evidence shows that it’s happened at least four times.





With so much attention focused on global warming, this chilly prospect has been all but forgotten. Given how catastrophic another ice age could be, one might be tempted to ask whether a human-caused increase in atmospheric and ocean temperatures will actually be a boon.

Throughout the history of the Earth, the planet's climate has been fluctuating between two dominant states: the greenhouse earth and the icehouse earth.These two climate states last for millions of years and should not be confused with glacial and interglacial periods, which occur only during an icehouse period and tend to last less than 1 million years. The Earth's climate is on a continuing, uneven cycle between the two states; the main factors involved in these changes in paleoclimate are believed to be the concentration of atmospheric carbon dioxide, changes in the Earth's orbit, and oceanic and orogenic changes due to tectonic plate dynamics. Greenhouse and icehouse periods have profoundly shaped the evolution of life on Earth.

this is one of those seemingly contradictory things. Global warming is making North America cold just has a funny ring to it. I'm of the opinion that that is exactly the case though so no need to argue that point. However, even though it makes sense in hindsight I saw no predictions, not even this fall, consistent with this outcome. That leads me to my next question/comments. I am curious about what progress has been made in measuring oceanic heat content.

Will these Kelvin waves tell us anything about heat content at depth? Do we really know how much heat content is at depth? Would bringing warmer water to the surface compound problems with global warming or mitigate them?

I see arguments along the lines of "most heat is stored in the ocean and warmer waters will trap more carbon and produce more carbon consuming organisms and bla bla bla" I don't buy it, but on the other hand, what evidence is there that the current state of the ocean will have predictable effects? Do those arguments deserve more consideration?


This is why it is necessary to call it climate change. While it is secondary to global warming, it is more than just warming but a major change in the overall climate.

P.S.
I knew Hurricanes like that pass between Jamaica and Cuba, but I never knew there was a deeper E-W "trench" between there and South Yucatan.

That's where the asteroid that wiped out the dinosaurs struck.

Edit: it was a bit further west, virtually on the Yucatan coast. Teach me to google, first.

i can see luv coming to a meeting....arrives in his '76 gas guzzling eldorado....puffing on a stoagie....clothes all from man made oil products i/e polyester....chops down a tree and burns it to light his stoagie...he starts off his lecture..."climate change....what climate change?"


LMAO that is hilarious! Can we all just agree Global Warming is real and call it truce, so there is no more ridiculous fighting like what took place on here yesterday?

Thanks Dr. M for the cool slides!

Other news, if you are interested in studying changes to carbon production in the upper ocean with Remote sensing...chime in about the study plans for EXPORT study that NASA is taking comments on now - April.

For other ocean junkies, OKEANOS is back in action and heading south to Florida and the GOM. NOAA is streaming some of their live ocean bottom data now.

Exciting events are afoot.

Awesome! Exactly what I was looking for =)


Fantastic! If you have more questions, don't hesitate to come on over to Dr. Rood's blog. There are many more knowledgeable folks than myself over there and we are always happy to help and/or answer questions.

Have a good one.

Global warming isn't making N. America colder over time. A below average temperature is not something that is out of the question, there is still regional variability within the climate. Link

As for ocean heat content measurement, Levitus et al 2012 (Link) really nailed it. They have created the standard for oceanic heat content measurement that produced:



and



When all that warm water comes up, especially in the Pacific in the case of an El-Nino world temperatures just skyrocket, see: 1998.

As for the mechanism by which the ocean stores heat energy, Trenberth Link Link started the discussion, and the newest research Link expands on that idea.

I hope this helps.
