Is Water Vapor in the Stratosphere Slowing Global Warming?

A mysterious drop in water vapor in the lower stratosphere might be slowing climate change

STRATOSPHERIC DRYING: Less water vapor in the stratosphere may have slowed global warming in recent years. Image: ©iStockphoto.com

Earth's stratosphere is a cold, dry place, above the troposphere—the bottom layer of the atmosphere we breathe on a daily basis. Ruled by winds and hosting everything from bacteria to long-distance jet travel, about the only way that water gets into this high-altitude layer 10 kilometers above the Earth's surface is when it billows up from the humid tropics, rising from the troposphere via the atmospheric interface known as the tropopause. But since 2001 there has been less water vapor in a narrow, lower band of the stratosphere thanks to cooler temperatures in the tropopause, and that may just be holding back global warming at ground level, according to new research published online in Science on January 28.

"We found that there was a surface temperature impact due to changes in water vapor in a fairly narrow region of the stratosphere," explains research meteorologist Karen Rosenlof of the National Oceanic and Atmospheric Administration's (NOAA) Aeronomy Laboratory, one of the authors of the study. "The reason for the water vapor change is the temperature drop at the interface between the troposphere and the stratosphere over the tropics. What we don't know is why the temperature dropped."

That temperature does seem to correlate, however, to sea-surface temperatures in the Pacific that, of course, follow El Niño–La Niña cycles, along with other trends. A new El Niño cycle—warmer surface waters—began last summer, which may mean that stratospheric water levels could change again. So this effect could either be the result of natural variability in Earth's climate, or yet another effect of carbon dioxide and other greenhouse gases like water vapor trapping more heat and thus warming sea-surface temperatures.

All told, stratospheric water vapor declined by 10 percent since 2000, based on satellite and balloon measurements, yet that was enough to appreciably affect temperatures at ground level according to climate models. "Reduce the water vapor and you have less long-wave radiation coming back down to warm the troposphere," Rosenlof says. Conversely, an apparent increase in water vapor in this region in the 1980s and 1990s exacerbated global warming.

Of course, the amount of water vapor in the atmosphere is also affected by another potent greenhouse gas—methane—which has unexpectedly failed to increase in recent years. "The other influence is methane, which breaks down into two water molecules and CO2 in the stratosphere," explains climate scientist Drew Shindell of NASA's Goddard Institute for Space Studies (GISS). "Methane's growth rate has dropped, so it'll have become a weaker source of stratospheric water, but we don't fully understand why its concentrations have not increased as rapidly in recent years as they did for the previous several decades."

In fact, the more than 100 percent increase in overall methane since the 18th century has made the stratosphere a wetter place, notes GISS climate modeler Gavin Schmidt. "What might have caused this effect? I can think of two factors: The 1997–98 El Niño might have moistened the lower stratosphere more than usual, and thus there has been a trend toward drying since then," he says. "A second idea might be related to changes in aerosol emissions from Asia, which have affected temperature profiles in the tropics and the properties of clouds."

And there remains little doubt that average temperatures are getting warmer at ground level; data from NOAA's National Climatic Data Center reveals that the last decade was the warmest since record-keeping began. More monitoring of the entire atmosphere as well as the whole panoply of greenhouse gases over the long term will be required to determine what's behind the lower stratospheric dry out—a set of observations imperiled by the current dearth of Earth observation satellites operated by the U.S. space program.

But one thing remains clear: More greenhouse gases in the atmosphere equals more warming. "It doesn't say that CO2 warming isn't going on," Rosenlof adds. A drier lower stratosphere may simply have slowed the warming caused by the thickening greenhouse gas blanket.

    Of course, we deniers have been saying forever that water vapor is overwhelmingly the biggest and most significant greenhouse gas. Methane can probably trump all other climate factors when enough of it gets loose.

    Just shut up already about the carbon footprint of my old full size Ford pickup. Such vehicles are a miniscule component of any change going on, as in tiny, tiny, tiny.

    And having pronounced all that, the true direction of climate appears to be towards a New Little Ice Age (NLIA). Those much-predicted solar sun spots simply aren't showing up yet and even if they do the big climate driver forcing NLIA may be something else entirely that none of the global warming have considered.

    My God... it never ends.. every time a global warming theory is debunked, or is found to be made up by "scientists" to support this theory, they come up with another "cause".

    Instead of printing every possibility or postulating on the next gotcha.. perhaps some real scientific research should be done and not some 1 year study. How about 50,000 year trending coupled with sun activity?

    If the scientific community could see just how stupid and lame they look with this constant reaching for why we aren't heating up and actually challenged their own data and theories perhaps they could win an argument. Right now it stands I have more faith in meteorologists who are global warming skeptics. They have been more correct lately and actually back their skepticism with raw data.

    The science community has diminished their standing in the wake of junk science reporting. Perhaps a "reboot" is in order, with (real) scientists who are skeptics, challenging the data and coming up with a more concise result.

    Well I can say that the pan evaporative rate around the world is slowing. This is a simple measurement that farmers have been doing for about 100 years. They just fill a pan of water up and measure how much evaporated that day.
    It's not easy to ignore 100+ years of that data pointing to slower and slower rates.

    Global warming, Global Dimming, Atmospheric water vapor levels, and fine particle pollution may all be playing a very complex game together. That would make one theory to explain all of the data very open to holes.

    I think one thing that everyone can agree on is something is happening, be it natural or man made or a combination, something is definitely changing in our environment.

    Every graph I have seen related to global warming/greenhouse gases has been filled with dips and spikes, but there is usually an overall trend to the measurements. Understanding what causes an unexpected dip or spike helps us improve our models. But it is not the dip or the spike that causes greatest concern, it is the overall trend. And the trend is toward more greenhouse gases in the atmosphere than we presetly have, localized dips notwithstanding.

    Instead of attacking one another, we need to support the process of refining the picture and developing models, critique the models based on available data and simulation, and set goals toward the benefits to humanity, not just to the benefit of ideology, clan, political party, national origin, or race.

    Actually for the past 10 years the trend has been down, hence the NLIA that is being touted in some circles. The fact of the matter is the "Concensus" was wrong and is being perpetuated for political and (in the case of people like Al Gore) monetary gain. Scientists are still pressured to support Climate change (Nice shift in billing from Global Warming eh?)

    Water vapor is a green house gas, i.e. it reflects and absorbs infrared radiation. If there is less water vapor in tropopause, then maybe this is why it is colder? It there any reason to believe that this is not the cause and effect going on, as opposed to the cooler temperatures drying the water vapor out of the tropopause?

    Mike Cook,

    Water vapor is a greenhouse gas, but it is not as long lived in the atmosphere as CO2. Methane-CH4 also does not last as long in the atmosphere as Co2. Co2 overwhelmingly trumps all other greenhouse gases, becasue it lasts for centuries in the atmosphere. Also, a NLIA would be considered climate change.

    Obviously if a planet raises it's input energy or energy release, the water should start to rise, absorbing some of this energy and appearing to cool the planet along certain levels. But more disturbing is the question, "Is this a precursor to the loss of water into space? Will the earth become a comet and spiral away from the sun?"

    I would expect this phenomenon to lag behind the dangerous rise in temperature, however. Once we reach such a level the outcome would be catastrophic and probably unpredictable.

    Somebody mentioned particulate pollution and I really think that dust and soot should get a lot more scrutiny as the major cause of Arctic Ice meltback and the recession of some Northern Hemisphere glaciers.

    In fact, if you look at the extremities of the summer Arctic ice cap meltback, you see that the vast majority of it occurs in the drop zone of the prevailing winds that carry dust from the Gobi, dust from the drought-stressed agricultural areas of Mongolia and NW China, and dust and soot from the accelerating industrial activities of China, South Korea, and Japan. All this airborne material head to the Arctic where it makes the Bering Sea one of the world's richest fisheries through fertilizing plankton.

    All this grime from the sky falls on the ice cap where when the sun returns in the summer it will greatly aid solar energy in melting the ice more efficiently. I think the effect of the trace gas carbon dioxide has been getting all the blame for something it didn't do. The greenhouse gases undoubtedly add something, but if we are amazed in coming years because the ice melt in the north continues but Arctic cold keeps on being amazingly cold in the winter, it is because dust and soot are much more significant as climate drivers than CO2.

    The Chinese will continue promising much more than they actually do in relation to Copenhagen deals, no doubt because China and Mongolia have been really cold this winter.

    All this brings up another subtle point. A New Little Ice Age (NLIA) is likely to make much of the world a drier place, which will really confuse the public because global warmers have been touting drought as a major threat on a hotter world. The NLIA is going to force news media to actually do serious homework before just amplifying far and wide whatever ridiculous study some warmer looking for a political promotion has put out there.

    Something IS happening. The trend now is "up" since 1650, but not as a straight line. We have an oscillation up: 31 years and then down 31 yerars. IPCC uses the latest up 1975-2001 as a"proof" for global warming. What shall they do during the "down" period 2002-2033? Well, we already hav an idea.

    CO2-fans avoid the (statistical) true but come up wiht more and more explanations on why whether does not behave as they predict. I would be easier (and more honest) to find out why their PREDICTIONS does not work. Because dogma does not work in science.

    There is one problem envolved in your thinking. You are right, CO2 stays in the atmosphere for a longer time than watervapour. But it does not matter at all if one molecule H2O goes out and is replaced of one other (or two). The amount is the same. That is many many many times more than CO2. So what you tell is plain and pure bullshit.

    Only AGW advocates say the debate is over. That's crap. They don't know what they're talking about. Read 'Climate of Belief' by Dr. Patrick Frank in Skeptic magazine (skeptic.com) The errors in climate models are 2,000% to 4,000%. It's hilarous the Warmers talk of AGW with certainty.

    You can look at global temp. data 1900-1999 in the NOAA website. I have analyzed these data. There's warming and cooling, not straightforward warming. But here's the catch and Warmers do not say this (or maybe they don't even know it), the margin of error in the data is bigger than the warming effect. In other words, the data are inconclusive. We cannot even say with certainty if the world warmed or cooled at least until 1990. I have the scientific paper on the uncertainty in temp. records if you want to read it.

    I propose that we also measure the quantity of Stupid Hysterical Imbecile Text (S.H.I.T) on the web versus, say, factual based discussions that apply logic to problems. My hypothesis is that homes that allow to much S.H.I.T. to come on their screens may corrupt the minds of young children leading them to fail in school and do drugs.

    Viewers of Pat Robertson or listeners of Rush Limbaugh can be tested against a population of ordinary people to see how S.H.I.T, once it enters the brain and mind of the victim, effects them.

    The real problem is that there's too many scientists doing too many studies. The more people involved and the more research done, the more flawed studies will be produced, it's inevitable. The skeptics don't care that the number of studies found to be flawed are disproportionate tiny compared to the studies still thought to be sound. Once it gets to the press, if there were a total of 5 studies done and 2 of them were flawed, people would be more likely to believe the research than if it was 5 flawed studies out of 1,000.

    As usual the earth's ecosystem's complex diverisity is staging various control measures and reactive responces to the ever changing status of our atmospheric mixture of chemicals dumped by nature and man. Earth is a very big place for such tiny critters like mankind. While our contributions to this planet over the last 6 or so millanias is barely dectictable overall when compared with the age of this rock it would be wise to be more earth friendly and monitor how the chemicals are having influance in the way earth responds to interactive effects with our presence.

    Sure.

    You are right, the debate is completely over regarding the driver of the currently observed change in temp being CO2, and the rate of currently observed warming.

    What will always be debated at the fringes of the science is what causes each little squigglie diversion from the warming trend.

    In asking for an explanation you have shown yourself incapable of distinguishing between first, second and third order effects.

    There is no debate on the first order drivers. Co2, Methane, Solar etc.

    There is less and less debate over what are the second order drivers, Volcanism, biological feedbacks, deep ocean currents etc.

    As to the third order drivers, they will always be essentially random due to their relationship to weather.

    The observation that CO2 has a longer lifetime in the atmosphere relates not to the speed with which molecules are exhanged, but with the rate at which the bulk of the gas can be removed.

    Cool the atmosphere and you will get rain nearly immediately. Warm it and there will be more evaporation.

    The atmosphere's water content is in near equilibrium for any given temperature.

    On the other hand, there time needed to reach equilibrium for CO2 is on the order of hundreds of years.

    And that is what puts CO2 in the drivers seat. Once it's up there, you can't readly remove it. Hence you can't readily remove it's warming effect.

    A warming effect that is enhanced by the increase in the water vapour content of the atmosphere.

    Good article.
    The Earth and its atmosphere are a very complex system. Many factors affect the climate. I am truly grateful to the many scientists who devote their lives to studying this difficult subject. Global warming is a fact. ascertaining the various causes and counter influences is difficult. Certainly the increase in Carbon dioxide and methane in the atmosphere contribute. And yes, even a gallon of extra petroleum burned adds to the problem.

    Those of us who care about the future of this fragile planet do our best to minimize our footprint. But with 6+ billion people, most of whom don't care, it is difficult.

    It is a shame that ignorant people make silly critical comments about this serious problem.

    Jack, what vendicar9 won't tell you is that water vapor and clouds aren't understood by catastrophic AGW GCM'ers, and they just assume they'll respond as a positive feedback loop. He'd prefer to play the chicken little card to ensure his funding rather than show the least bit of modesty or humility. GCM's don't make "predictions", the create "climate scenarios". This allows them infinite upside and zero downside. You should read some from Dr. Roy Spencer, Richard Lindzen, and Dr. Roger Pielke SR. They give unbiased views on climate science. Forget about Scientific? American when it comes to this subject.

    Yes AGW theory is sensible and entirely plausible. But look at the hard data to test how good it is in explaining global temperature trend. Temperature records prior to 1940s have a margin of error 0.1-0.2 C so they are not very reliable. Look at the temperature data 1940-1999 and compare it with atmospheric CO2 concentration for the same period. I have done a statistical analysis on this and determine their correlation (R^2).

    CO2 can explain about half of the observed variability in global temperature. The other half may be attributed to unknown variables, confounding variables or inherent variability. This does not debunk AGW but it also shows that there are other factors influencing global temperature that cannot be ignored. We cannot say with certainty that CO2, especially anthropogenic CO2 which is a small part of atmospheric CO2, is the main driver of global temperature. Yes it may have a significant influence, though correlation is not causation, but that is not the whole story.

    And there's a problem here. The margin of error in global temperature records makes statistical analyses for or against AGW theory inconclusive. The laws of physics support the atmospheric greenhouse effect which is the physical mechanism of AGW. But this only means AGW is possible, it does not establish a cause and effect relationship between CO2 and global temperature because the laws of physics also support other man-made and natural phenomena that influence global temperature. Climate science is far from settled.

    It has been known for a long time that high level stratospheric clouds cause warming and those in the troposphere and low-level stratiform clouds, cooling, and for the last deacde the global climate models have been doing a reasonable job of simulating both.

    However one need not rely on computer models, but rely on direct observations of what is going on, and direct obsrevation shows that clouds in the low-level stratophere are disappating - thus adding to the increase in the earth's temperature.

    That's a very good lecture by Richard Alley. CO2 drives temperature throughout earth's 4.6 billion yr history. Man started contributing atmospheric CO2 only in the last 100 yrs. Nature is perfectly capable of changing the climate without man's help. But of course we should not make it worse. Curiously he did not mention water vapor which is a more significant greenhouse gas. There 30 times more H2O molecules in the air than CO2.

    There's an obvious reason why CO2 should track temperature closely. There are more CO2 in the oceans than in the atmosphere. Rising temp. releases the CO2 from the oceans into the atmosphere and starts a positive feedback loop. And this correlation between CO2 and temp. will show whether or not other factors have more significant impact on climate.

    Btw, Dr. Alley is also the one who proposed the Big Freeze theory. He observed that in the geologic past, there were drastic climate changes 10C or more drop in temp. in 10-20 yr periods. (I'm not sure this is caused by CO2) He proposed that rising temp. could melt the natural glacial dams and bring fresh water into the oceans and shut down the "ocean thermal conveyor." This will bring the next ice age very soon.

    We should be concentrating on how to mitigate whatever climate changes are occurring rather than attempting to prevent any changes (a, currently, impossible dream).

    If we are in a cooling trend, how do we ascertain that enough foods will be produced to prevent massive starvation, and how can me make inexpensive but reliable sources of heating available to those who may not have needed them before, etc.? If we are in a warming trend, we need to mitigate any potentially dangerous results of that warming. There are better uses of our money and science than trying to alter the inevitable.

    If you perterb a chaotic system it becomes more chaotic. In a climate system that means that weather changes more dramatically. And this means a less stable climate for growing crops. More harsh temperatures, more drouts, more heavy rains, etc.

    Finally, there is also a moral obligation to protect more than just ourselves from the ongoing effects of warming, and biosphere degredation in general.

    And that is why Denialists are pure filth. They lack the balls, the brainpower, and the morality to take responsibility for thier own actions.

    Dr. Strangelove,

    "Curiously he did not mention water vapor which is a more significant greenhouse gas."

    Water vapor is usually considered a feedback. Carbon dioxide is usually considered a forcing.

    "This will bring the next ice age very soon."

    Very few of the climate change scenarios include an ice age.

    Hey mikey....better take a look at head denialist, roy spencer's page, where after a couple of "global cooling" rants, he has finally posted the temperature anomaly of 0.72 degrees C for January 2010 on his graph, about equal to the el Nino spike year of 1998.

    NASA Aqua Sea Surface Temperatures Support a Very Warm January, 2010
    February 4th, 2010
    When I saw the record warmth of our UAH global-average lower tropospheric temperature (LT) product (warmest January in the 32-year satellite record), I figured I was in for a flurry of e-mails.

    Oooh...and don't look now, but solar cycle 24 is finally showing some sunspots and our sun is awakening, and solar irradiance is surely to increase over the next few years!

    State of the Climate, Global Analysis by NOAA
    Annual 2009


    Global Highlights

    Global land and ocean annual surface temperatures through December tied with 2006 as the fifth warmest on record, at 0.56°C (1.01°F) above the 20th century average.

    The 2000-2009 decade is the warmest on record, with an average global surface temperature of 0.54°C (0.96°F) above the 20th century average. This shattered the 1990s value of 0.36°C (0.65°F).

    Ocean surface temperatures (through December) tied with 2002 and 2004 as the fourth warmest on record, at 0.48°C (0.86°F) above the 20th century average.

    Land surface temperatures through December tied with 2003 as the seventh warmest on record, at 0.77°C (1.39°F) above the 20th century average.

    Or better yet mikey, check this out by lead denialist roy spencer, and his "latest global temperature graph."

    http://www.drroyspencer.com/latest-global-temperatures/


    WOW!....2010 is already starting out with an el Nino warming and now sunspots appearing as Cycle 24 gets rolling!

    I wouldn't bet on that "global cooling" nonsense!

    As El Nino warms the sea, it will gas off dissolved CO2, causing an enhanced greenhouse effect in a closed vicious cycle, causing El Nino to grow still stronger. Only when dissolved CO2 reaches a minimum will the phenomenon recede.

    David Biello makes a error when he writes: "...about the only way that water gets into this high-altitude layer 10 kilometers above the Earth's surface is when it billows up from the humid tropics...", and he does so right after naming a very significant contributor to stratospheric h2o - high flying jets. In general, for every thirteen molecules of co2 in jet exhaust, there are 14 molecules of h2o. Hence, jet exhaust, in both the stratosphere and troposphere, contributes NEW water to the hydrologic cycle and may well act as a forcing, and may be altering the cycle such that h20 accumulates and persists in new volumes and rythyms.
