Why Southeast Greenland's glaciers have slown down since 2005

I'm in San Francisco for the annual meeting of the American Geophysical Union, the world's largest gathering of climate scientists. I saw ten or so great talks yesterday (and five really boring ones!) Here's a summary of the the most interesting talk I heard yesterday:

If you plan on owning ocean front property after the year 2050, you should pay close attention to the glaciers In Greenland. Greenland holds enough ice to raise global sea level by over 20 feet (6.5 meters), should its ice cap completely disintegrate--though such an event would likely take centuries to occur. Still, should the climate warm 2°C or more this century, partial melting of the Greenland Ice Sheet could readily raise global sea level by a meter or more by 2100. That's why scientists reacted with concern during 2003 - 2005, when all of the glaciers in southeastern Greenland accelerated in synchrony to speeds 30% to 210% faster than they had flowed in 1996. As they sped up, the glaciers began dumping huge amounts of ice into the ocean off the coast of southeast Greenland, more than doubling Greenland's contribution to global sea rise, to .57 mm/year. Would the glaciers keep accelerating, bringing about an increasing disintegration of the Greenland Ice Sheet? Nobody knew, since computer models of glacial dynamics were (and still are) in a primitive state.


Figure 1. Helheim Glacier in southeast Greenland, in three images captured in 2004, 2005, and 2006. The glacier accelerated significantly in 2005, and the face of the glacier retreated 5 km inland (middle frame) compared to 2004. However, by the summer of 2006, the acceleration ceased, the the glacier returned back to its 2004 position. Image credit: Ian Howat, University of Washington.

Well, it turned out that 2005 was the peak of the glacial acceleration event. The glaciers in southeast Greenland have returned to where they were eight or nine years ago--still causing a net loss of mass that is raising global sea level, but not as fast as in 2003 - 2005. In a talk titled, "Ocean regulation of glacier dynamics in south-east Greenland and implication for ice sheet mass changes", Tavi Murray and colleagues from the UK's Swansea University presented a plausible theory for why this strange synchronous speed-up and slow-down occurred. Using satellite, aircraft, and surface observations, the researchers found that air temperatures in the region did not vary much over 2003 - 2005 (Figure 2). Thus, a major increase in temperature could be ruled out as the cause of the glacier surge. However, study of the ocean temperatures near the coast revealed strong clues that ocean currents were responsible for the surge.

Figure 2. Ocean currents off the east coast of Greenland feature the cold East Greenland Coastal Current flowing north to south (white arrows) and the warm Irminger Current flowing south to north (red arrows). Image credit: Arctic Climate Impact Assessment.

Ordinarily, the southeast coast of Greenland features a cold water current flowing north to south, called the East Greenland Coastal Current (EGCC). Much of the cold water for this current is supplied by melting of the 14 glaciers in southeast Greenland that empty into the sea (two of these glaciers, Kangerdlugssuaq and Helheim, represent 35% of east Greenland's total glacial discharge). A few hundred kilometers offshore, a warm water current called the Irminger Current flows the opposite direction, bringing warm water from the North Atlantic northward. In 2003, it happened that weather conditions over Greenland brought an unusually low amount of run-off of precipitation. With little new mass pushing the glaciers seaward, the glaciers responded by greatly reducing the amount of ice they dumped into the ocean by the shore. As a result, the East Greenland Coastal Current slowed down and warmed, which allowed the warm Irminger Current to advance towards the coast, warming the coastal waters even more. All that warm water near the coast began melting the glaciers where they reached the sea, causing the glaciers all along the southeast coast of Greenland to accelerate and rapidly thin between 2003 - 2005. By 2006, the thinning glaciers had dumped so much new ice into the ocean near the coast that the waters cooled and the East Greenland Coastal Current re-established itself. This cooled the glaciers at their marine termination points and slowed down the glacial surge, putting the glaciers back where they had been before 2003. This is a classic example of a negative feedback process--a change in weather conditions which generates a response, but the response creates conditions that tend to dampen the response.


Figure 3. Average temperatures for the only station in southeast Greenland with a century-long temperature record, Angmagssalik (called Ammassalik on the map in Figure 2). Temperatures in southeast Greenland during the 1930s and 1940s were similar to today's temperatures, suggesting that glacial surges like we witnessed in 2005 may have also occurred in the 1930s and 1940s, before we had monitoring capability. Image credit: NASA Goddard.

Commentary
As I commented in my previous post, Arctic sea ice loss appears to have created a new atmospheric circulation pattern that brings more warm air in the Arctic, creating a positive feedback loop that causes even more sea ice loss. This positive feedback loop was a bad news surprise that our climate models did not predict. Now we have evidence of a good news surprise that no model predicted--a negative feedback loop that acts to keep the southeast portion of Greenland's Ice Sheet from runaway glacial acceleration. We can expect many more surprises--good and bad--over the coming decades, as our climate responds to the huge shove human activities are giving it.

Ricky Rood in Copenhagen
Our Climate Change expert, Dr. Ricky Rood, is in Copenhagen for the COP15 climate change treaty negotiations. His latest post, called Have you no sense of decency, sir, at long last? makes for very interesting reading on how the U.S. is "wasting its intellect and time on disruptions designed to play to people at home".

Next post
I'll have another post from the AGU meeting Thursday or Friday this week.

Now for the ultimate blog killer (although it is late), string theory anyone?

Hi knothead. ;>) long time no talk.
String theory? No thanks. Not a big fan of Berkley Astro Physics.
And no thanks on "bubble neucleation" being the vehicle to travel to their parallel universes.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
431 AM CST THU DEC 17 2009

.SHORT TERM...TODAY THROUGH TONIGHT...MORE RAINFALL...LOCALLY
HEAVY...WILL BE SPREADING INTO THE REGION LATE TODAY AND ESPECIALLY
TONIGHT AND INTO THE MORNING HOURS ON FRIDAY. UNFORTUNATELY...THE
AREAS THAT WE EXPECT THE HEAVIER RAINFALL TONIGHT AND FRIDAY MORNING
WILL BE THE SAME AREAS THAT RECEIVED THE VERY HEAVY RAINFALL EARLIER
THIS WEEK. SOME LOCATIONS IN NORTHERN BALDWIN AND ESCAMBIA COUNTIES
OF ALABAMA SAW UP TO LOCALLY 10 INCHES OF RAIN...WITH A LARGE AREA
GENERALLY ALONG AND SOUTH OF A WIGGINS...LUCEDALE...CITRONELLE...
MONROEVILLE...GREENVILLE LINE RECEIVING AT LEAST 4 INCHES AND IN
SOME INSTANCES 4 TO 6 INCHES OF RAINFALL. THIS EARLIER RAINFALL
RESULTED IN WIDESPREAD AREAL AND RIVER FLOODING...SOME OF WHICH
STILL CONTINUES. AS A RESULT...WE WILL ISSUE A FLASH FLOOD WATCH
VALID FOR TONIGHT AND EARLY FRIDAY FROM STONE AND GEORGE COUNTIES OF
MISSISSIPPI...NORTHEASTWARD INTO ALABAMA ROUGHLY ALONG AND SOUTH OF
I-65...AND FOR ALL OF THE WESTERN FLORIDA PANHANDLE. WE EXPECT AN
ADDITIONAL 2 TO 3 INCHES OF RAINFALL OVER THAT AREA...WITH THE
REMAINDER OF THE FCST AREA LIKELY RECEIVING 1 TO 2 INCHES OF RAIN.
AS IS USUALLY THE CASE...LOCALIZED HIGHER AMOUNTS WILL BE POSSIBLE.

ALL OF THIS ADDITIONAL RAIN WILL DEVELOP IN ASSOCIATION WITH A
DEVELOPING LOW PRESSURE AREA OVER THE FAR WESTERN GULF OF MEXICO
EARLY THIS MORNING THAT IS EXPECTED TO MOVE EAST-NORTHEAST ACROSS
THE GULF...AND BE APPROACHING THE EASTERN FLORIDA PANHANDLE
COASTLINE BY AROUND MIDDAY FRIDAY. MODELS ARE IN GOOD AGREEMENT WITH
THIS SCENARIO...WITH ALL SOLUTIONS SPREADING RAINFALL INTO THE FCST
AREA BY THIS EVENING AS THE LOW APPROACHES. THE TRACK OF THE LOW IS
EXPECTED TO REMAIN SOUTH OF THE AREA OVER THE GULF...AND AS A RESULT
RAINS SHOULD BE MORE OF A STEADY STRATIFORM VARIETY AS ISENTROPIC
LIFTING MATERIALIZES NORTH OF THE LOW. BUT SOME ISOLATED EMBEDDED
HEAVIER SHOWERS AND THUNDERSTORMS CAN BE EXPECTED...ESPECIALLY FOR
THE COASTAL COUNTIES. ONE SAVING GRACE WITH THIS SYSTEM VERSUS THE
ONE WE HAD EARLIER IN THE WEEK IS THAT THIS ONE WILL BE MOVING MUCH
MORE QUICKLY ACROSS THE FCST AREA. THIS FASTER MOVEMENT SHOULD
RESULT IN LESS RAINFALL THAN WHAT WAS EXPERIENCED EARLIER IN THE
WEEK...BUT STILL WILL BE ENOUGH TO CAUSE AT LEAST SOME ADDITIONAL
FLOODING CONCERNS. STAY TUNED.

Have any of you bothered to calculate how much the combustion of natural gas and other hydrogen containing fossil fuels have raised sea levels? Each gram of natural gas that burns produces 2.25 grams of water vapor. that water vapor eventually falls to the ground as rain and then flows into the oceans.

GFS brings in more moisture than some of the other models. However, as of tonight even the drier models are starting to bring in a little bit more moisture now. Another disturbance is expected to cross NC Sunday night and even that may bring a chance of snow here after the bigger one leaves.



Some of these snow total maps I find very inaccurate based on the amount of moisture with the low confidence and other models saying showing different totals. Snow totals here in look about right but when you head east of Winston Salem, NC to Raleigh it may be more of a mix and cold rain east of there changing to snow as the moisture leaves. We will see later Thursday for sure if not Friday morning as the models change. GFS wants to bring in so much moisture so it cools faster from top down to allow for more accumulation. The drier models are now leaning to this but not as much yet to allow for light accumulation around south-eastern Greensboro, Asheboro and Raleigh NC.

Quoting CatastrophicDL:

ROFL! You know while I understand and feel it is only logical that humans somehow impact the weather patterns of the earth, all this arguing makes me think of the evolution/creation argument. I'm thinking that when scientists can make primordial sludge evolve into a human then I'll be on board. In every case, I don't feel science has proved it's point.


Hi DL. Nice to see you around.

You have inspired me. I might create a blog entry to discuss just that (I'm pretty lazy when it comes to that). I'm a math/logic guy if anyone hasn't noticed.

Just as a hint, remember the old claim that if you have enough monkeys typing they would write a novel? Don't hear it so much anymore for a reason. Key is it is always qualified with "write every word of," which is valid but the penultimate example of propaganda, imo. Why? Someone would have to pull all those words together to make them coherent.

Math is math. Probability is probability (my actuarial textbook was 50 years old when I studied and is now... well... I'll just say a lot older and still in use).

Now for the ultimate blog killer (although it is late), string theory anyone?

Still excited about the new smasher. Looks like they've got it on the right track and we'll get some interesting insights within the next year. :)

Goodnight. Nice read tonight. Thanks all.

Looks like im going to get hammered this this weekend in north-west North Carolina.

Wilkes County schools already dismissing at 1pm Friday for Christmas break. I hope we get to go Friday so they don't cut off one day of our Christmas break next Monday. < With the snow totals looking like this I doubt we will even be going back then for a makeup day...


Winter Storm watches already issued for south-western NC so sometime later today the NWS in Blacksburg and the one in Raleigh will be issuing what they need. Expect a swath of watches to go up 24hours in advance.

I might post some pics here if this half a foot snow verifies from the GFS.

interesting


Recent GFS models (the last 4) for 12-28-09 places precip and/or a L pressure over the SW GOM. It had N Central TX in the "bulls-eye" with the 12Z run. Here with the 00Z run, N TX just misses out.

At least there is some type of consistency here. We are also about 11 1/2 days out. The general rule is long range models past 7 days are unreliable. The NCEP, the people who generate these reports actually stated that It probably will not be until 12-24-09 until the L that moves into CA approaches. If it gets squeezed to the South, cold/possible frozen precip. If it takes the Northern route (which is possible, however looks unlikely) temps would moderate to near normal. The last run supresses the moisture to the S TX, but keeps the cold air entrenched.

Possibility of snow in the Hill Country, south to near Corpus Christi, across to near Houston (again) and into LA.

if the gfs output ends up verifying, those numbers WILL be underdone, IMO.

There is going to be 10:1 to 15:1 snow fall ratios from central virginia to philly at the height of the storm. So, if there is 0.80 inches of precipitation in Philly, that's at least 8 inches. If there is 1.5 inches of precip somewhere north of richmond on I-95, you are talking about possibly 18 inches.

Let's just say I'm very happy about the GFS output considering that I'll arrive in Philly just before the fun begins, and I suspect, the results will just get even better.


I agree with those snow ratio. The mid level dynamics appear the greatest in Appalachians and work its way northeastward towards eastern Virginia.

He certainly gave the Romans a run for their money. If I recall there is a winery named Vercingetorix. I forget the region, but do remember that I was unfamiliar with the name at the time. I learned soon enough. Still a certain pride there.

drak how confident should we be in these model runs? 0z are the most reliable right?


The 00z and 12z runs are the best runs with the new data input in the models. There probably will be some fluctuations over the days to come, but the GFS 00z and the NAM 00z look good as far as track and handling the jet stream. The models trends are definitely in favor of a major east coast storm.

Assuming that much of this, especially north of central virginia, is all snow, there looks to be some nice totals from richmond to philly.

Sorry NYC and Boston.

Drak, looks like you nailed the jet stream not allowing the storm to complete the trek up the east coast. Good call at this point.

Been lurking again -- jeez people, please read all the data/info and stop cherry picking. Dr. M. posts an interesting snippet on the Greenland glacier slow down and the AGW crowd yells "SEE, TOLD YA", but not two days before this, he posted perhaps the single most sobering data set and graph I have ever seen on Artic ice levels -- not only model runs showing the Arctic ice free by 2100, but real world observation showing the models WAY OFF in a bad way (possibly ice free in less than 15 years!) How can people be SO certain they are right on either side? We need to watch, read, learn and probably ACT starting now, even if there is a chance science isn't "100% right" quite yet (is it really possible they are 100% wrong?) Trying my best to resist the flat earth folks right now. I think Columbus is sailing.
