(Phys.org) —Flying low and slow above the wild, pristine terrain of Alaska's North Slope in a specially instrumented NASA plane, research scientist Charles Miller of NASA's Jet Propulsion Laboratory, Pasadena, Calif., surveys the endless whiteness of tundra and frozen permafrost below. On the horizon, a long, dark line appears. The plane draws nearer, and the mysterious object reveals itself to be a massive herd of migrating caribou, stretching for miles. It's a sight Miller won't soon forget.

"Seeing those caribou marching single-file across the tundra puts what we're doing here in the into perspective," said Miller, principal investigator of the in Arctic Reservoirs Vulnerability Experiment (CARVE), a five-year NASA-led field campaign studying how climate change is affecting the Arctic's carbon cycle.

"The Arctic is critical to understanding ," he said. "Climate change is already happening in the Arctic, faster than its ecosystems can adapt. Looking at the Arctic is like looking at the canary in the for the entire Earth system."

Aboard the NASA C-23 Sherpa aircraft from NASA's Wallops Flight Facility, Wallops Island, Va., Miller, CARVE Project Manager Steve Dinardo of JPL and the CARVE science team are probing deep into the frozen lands above the Arctic Circle. The team is measuring emissions of the carbon dioxide and methane from thawing permafrost—signals that may hold a key to Earth's climate future.

What lies beneath

Permafrost (perennially frozen) soils underlie much of the Arctic. Each summer, the top layers of these soils thaw. The thawed layer varies in depth from about 4 inches (10 centimeters) in the coldest tundra regions to several yards, or meters, in the southern boreal forests. This active soil layer at the surface provides the precarious foothold on which Arctic vegetation survives. The Arctic's extremely cold, wet conditions prevent dead plants and animals from decomposing, so each year another layer gets added to the reservoirs of organic carbon sequestered just beneath the topsoil.

Over hundreds of millennia, Arctic permafrost soils have accumulated vast stores of organic carbon - an estimated 1,400 to 1,850 petagrams of it (a petagram is 2.2 trillion pounds, or 1 billion metric tons). That's about half of all the estimated organic carbon stored in Earth's soils. In comparison, about 350 petagrams of carbon have been emitted from all fossil-fuel combustion and human activities since 1850. Most of this carbon is located in thaw-vulnerable topsoils within 10 feet (3 meters) of the surface.

But, as scientists are learning, permafrost - and its stored carbon - may not be as permanent as its name implies. And that has them concerned.

"Permafrost soils are warming even faster than Arctic air temperatures - as much as 2.7 to 4.5 degrees Fahrenheit (1.5 to 2.5 degrees Celsius) in just the past 30 years," Miller said. "As heat from Earth's surface penetrates into permafrost, it threatens to mobilize these organic carbon reservoirs and release them into the atmosphere as carbon dioxide and methane, upsetting the Arctic's carbon balance and greatly exacerbating global warming."

Current climate models do not adequately account for the impact of climate change on permafrost and how its degradation may affect regional and global climate. Scientists want to know how much permafrost carbon may be vulnerable to release as Earth's climate warms, and how fast it may be released.

CARVing out a better understanding of arctic carbon

Enter CARVE. Now in its third year, this NASA Earth Ventures program investigation is expanding our understanding of how the Arctic's water and carbon cycles are linked to climate, as well as what effects fires and thawing permafrost are having on Arctic carbon emissions. CARVE is testing hypotheses that Arctic carbon reservoirs are vulnerable to climate warming, while delivering the first direct measurements and detailed regional maps of Arctic carbon dioxide and methane sources and demonstrating new remote sensing and modeling capabilities. About two dozen scientists from 12 institutions are participating.

The CARVE scientists observed episodic, localized bursts of methane being emitted from the tundra as the spring thaw progressed northward over Alaska's North Slope in May and June 2012. Reds and yellows represent the highest concentrations of methane, and blues the lowest. The methane is released from the topsoil as it thaws. Credit: NASA/JPL-Caltech

"The Arctic is warming dramatically - two to three times faster than mid-latitude regions - yet we lack sustained observations and accurate climate models to know with confidence how the balance of carbon among living things will respond to climate change and related phenomena in the 21st century," said Miller. "Changes in climate may trigger transformations that are simply not reversible within our lifetimes, potentially causing rapid changes in the Earth system that will require adaptations by people and ecosystems."

The CARVE team flew test flights in 2011 and science flights in 2012. This April and May, they completed the first two of seven planned monthly campaigns in 2013, and they are currently flying their June campaign.

Each two-week flight campaign across the Alaskan Arctic is designed to capture seasonal variations in the Arctic carbon cycle: spring thaw in April/May, the peak of the summer growing season in June/July, and the annual fall refreeze and first snow in September/October. From a base in Fairbanks, Alaska, the C-23 flies up to eight hours a day to sites on Alaska's , interior and Yukon River Valley over tundra, permafrost, boreal forests, peatlands and wetlands.

The C-23 won't win any beauty contests - its pilots refer to it as "a UPS truck with a bad nose job." Inside, it's extremely noisy - the pilots and crew wear noise-cancelling headphones to communicate. "When you take the headphones off, it's like being at a NASCAR race," Miller quipped.

But what the C-23 lacks in beauty and quiet, it makes up for in reliability and its ability to fly "down in the mud," so to speak. Most of the time, it flies about 500 feet (152 meters) above ground level, with periodic ascents to higher altitudes to collect background data. Most airborne missions measuring atmospheric carbon dioxide and methane do not fly as low. "CARVE shows you need to fly very close to the surface in the Arctic to capture the interesting exchanges of carbon taking place between Earth's surface and atmosphere," Miller said.

Onboard the plane, sophisticated instruments "sniff" the atmosphere for greenhouse gases. They include a very sensitive spectrometer that analyzes sunlight reflected from Earth's surface to measure atmospheric carbon dioxide, methane and carbon monoxide. This instrument is an airborne simulator for NASA's Orbiting Carbon Observatory-2 (OCO-2) mission to be launched in 2014. Other instruments analyze air samples from outside the plane for the same chemicals. Aircraft navigation data and basic weather data are also collected. Initial data are delivered to scientists within 12 hours. Air samples are shipped to the University of Colorado's Institute for Arctic and Alpine Research Stable Isotope Laboratory and Radiocarbon Laboratory in Boulder for analyses to determine the carbon's sources and whether it came from thawing permafrost.

The CARVE campaign flights are conducted aboard a specially instrumented NASA C-23 Sherpa aircraft from NASA's Wallops Flight Facility, Wallops Island, Va. Most of the time, the CARVE scientists fly the plane "down in the mud," at about 500 feet (152 meters) above the ground. The low altitude above the Arctic surface allows the scientists to measure interesting exchanges of carbon taking place between Earth's surface and atmosphere. Credit: NASA/JPL-Caltech

Much of CARVE's science will come from flying at least three years, Miller says. "We are showing the power of using dependable, low-cost prop planes to make frequent, repeat measurements over time to look for changes from month to month and year to year."

Ground observations complement the aircraft data and are used to calibrate and validate them. The ground sites serve as anchor points for CARVE's flight tracks. Ground data include air samples from tall towers and measurements of soil moisture and temperature to determine whether soil is frozen, thawed or flooded.

A tale of two greenhouse gases

It's important to accurately characterize the soils and state of the land surfaces. There's a strong correlation between soil characteristics and release of carbon dioxide and methane. Historically, the cold, wet soils of Arctic ecosystems have stored more carbon than they have released. If climate change causes the Arctic to get warmer and drier, scientists expect most of the carbon to be released as carbon dioxide. If it gets warmer and wetter, most will be in the form of methane.

The distinction is critical. Molecule per molecule, methane is 22 times more potent as a greenhouse gas than carbon dioxide on a 100-year timescale, and 105 times more potent on a 20-year timescale. If just one percent of the permafrost carbon released over a short time period is methane, it will have the same greenhouse impact as the 99 percent that is released as carbon dioxide. Characterizing this methane to carbon dioxide ratio is a major CARVE objective.

There are other correlations between Arctic soil characteristics and the release of carbon dioxide and methane. Variations in the timing of spring thaw and the length of the growing season have a major impact on vegetation productivity and whether high northern latitude regions generate or store carbon.

CARVE is also studying wildfire impacts on the Arctic's carbon cycle. Fires in boreal forests or tundra accelerate the thawing of permafrost and carbon release. Detailed fire observation records since 1942 show the average annual number of Alaska wildfires has increased, and fires with burn areas larger than 100,000 acres are occurring more frequently, trends scientists expect to accelerate in a warming Arctic. CARVE's simultaneous measurements of greenhouse gases will help quantify how much carbon is released to the atmosphere from fires in Alaska - a crucial and uncertain element of its carbon budget.

Early results

The CARVE science team is busy analyzing data from its first full year of science flights. What they're finding, Miller said, is both amazing and potentially troubling.

"Some of the methane and carbon dioxide concentrations we've measured have been large, and we're seeing very different patterns from what models suggest," Miller said. "We saw large, regional-scale episodic bursts of higher-than-normal and methane in interior Alaska and across the North Slope during the spring thaw, and they lasted until after the fall refreeze. To cite another example, in July 2012 we saw methane levels over swamps in the Innoko Wilderness that were 650 parts per billion higher than normal background levels. That's similar to what you might find in a large city."

Ultimately, the scientists hope their observations will indicate whether an irreversible permafrost tipping point may be near at hand. While scientists don't yet believe the Arctic has reached that tipping point, no one knows for sure. "We hope CARVE may be able to find that 'smoking gun,' if one exists," Miller said.

Other institutions participating in CARVE include City College of New York; the joint University of Colorado/National Oceanic and Atmospheric Administration's Cooperative Institute for Research in Environmental Sciences, Boulder, Colo.; San Diego State University; University of California, Irvine; California Institute of Technology, Pasadena; Harvard University, Cambridge, Mass.; University of California, Berkeley; Lawrence Berkeley National Laboratory, Berkeley, Calif.; University of California, Santa Barbara; NOAA's Earth System Research Laboratory, Boulder, Colo.; and University of Melbourne, Victoria, Australia.

28 years of climate blame crisis fear mongering and needless CO2 panic was a wet dream come true for you lazy copy and paste news editors and a war crime committed by believers and pandering politicians for condemning billions of helpless children to the greenhouse gas ovens of an exaggerated crisis. This was another Iraq War!
PROOF of exaggeration is the fact that science could if they wanted to end this costy debate instantly:
Stop cursing neocons and oil execs because it's the world of science you remaining believers should be venting frustration at for they refuse to say anything beyond "could be" a crisis and it's been 28 years! All science has to do to end this costly debate is say their crisis WILL happen and is unavoidable, eventual and or ultimately an actual crisis of climate from Human CO2, otherwise 28 years of "maybe" proves it "won't be".
Science needs to step up to the plate and say it WILL happen or admit exaggeration because the ultimate crisis needs the ultimate warning and proof. This isn't a theory any longer; it's about the Earth's survival the scientists are telling us.

This particular feedback loop is one of the top two we are facing (the other being rising oceans). If it is true that permafrost in the artic is beginning to melt, and if the melting stimulates the release of the carbon stored there as either methane or carbon dioxide, then there is nothing man can do to stop the warming that will follow.

People are waking up, as is evidenced every night on the news. Even in China. I just hope for the sake of my children and grandchildren that it's not too late. I suspect, however, that my hope might be forlorn.

For the first time in my life I actually hope there is a god. If there is, maybe it will step in and stop this stupidly short-sighted race from annihilating itself.

Err, No - since the LIA was a dip in temp below the norm and the MWP was a rise above the norm ( if it was global ) then there existed a stasis where temps were more stable ... which is where your plants likely came from.

Truth is increasing CO2 or Methane does not increase their warming potential, much like pouring 10 gal of water into a 5 gal container, or putting one mirror on top of another one.

Here's something that's new! Anonymous cowards will not get to walk in and shout their illogic without consequence anymore, Ed Beauregard. You talk about shouting "fire" but you go around trolling every climate story you can find without ever giving your name or that all you do is parrot what the Catholic Church says. Typical for Cincinnati, really. Or do you still claim to live in Greenland?

Hey, people. There aren't many like this. They're a social disease. When you come across one, find an excuse to go to an out of the way place and deal with at least one source of CO2. In fact I think that local shit-for-brains Jim Karlock is going to be showing Mr. Beauregard a lot of interest. When your kids are living in hell, are you going to be proud that you let people like this shout over any rational debate? What are you going to tell them is the reason you didn't?


"Shit for brains" - that is my expression.

These two quotes say it all about the phony global warming scenario.

"No matter if the science is all phony, there are collateral environmental benefits... [C]limate change [provides] the greatest chance to bring about justice and equality in the world."
—Christine Stewart, Canadian Environment Minister.

You were on the right track -- until you used a Harper-appointed Conservative for credibility. Remember, for accuracy, credibility and Conservative must be combined in the same sentence with a negative.

..."Will increased CO2 promote higher agricultural yields for the starving people's of the world?" hmmmm.


No dumdum, for a myriad of reasons. ...


A myriad of reasons? Like what? Plants don't use up CO2? Many plants are edible? Increases in atmospheric CO2 could increase the plants as food supply?

Planting more orchards in Africa to soak up that increasing CO2 is not a good idea?

No solutions for it, really? That seems to be the theme from the warm-mongers.

Never in the history of mankind has increasing taxes changed the weather … or the CO2 balance in the atmosphere.

Quite a pile of gish gallop there. There have been a lot of studies done to see how plants, especially food plants, will react to an atmosphere with a higher CO2 content and the higher temperatures associated with that. Take a few minutes and learn about them.

No one said no solutions, the problems relates to expense and political will.

You are just parroting the mantra you've heard somewhere else. Very typical of the bulk of people arguing against AGW.

Hey look Uba Dumdum, another one of those headlines that some whoever is putting out to trick you and your deluded mindless rabble. Or whatever.

So why didn't you comment on this one? How do the physics work in this case?

UTuba lacks the humour to be entertaining, the knowledge to be informative, and has all the charm and attraction of a deceased rat which suffered from leprosy and incontinence.
