Unprecedented May heat in Greenland; update on 2011 Greenland ice melt
The record books for Greenland's climate were re-written on Tuesday, when the mercury hit 24.8°C (76.6°F) at Narsarsuaq, Greenland, on the southern coast. According to weather records researcher Maximiliano Herrera, this is the hottest temperature on record in Greenland for May, and is just 0.7°C (1.3°F) below the hottest temperature ever measured in Greenland. The previous May record was 22.4°C (72.3°F) at Kangerlussuaq (called Sondre Stormfjord in Danish) on May 31, 1991. The 25.2°C at Narsarsuaq on June 22, 1957 is the only June temperature measured in Greenland warmer than yesterday's 24.8°C reading. Wunderground's extremes page shows that the all-time warmest temperature record for Greenland is 25.5°C (77.9°F) set on July 26, 1990. The exceptional warmth this week was caused by the combination of an intense ridge of high pressure and a local foehn wind, said the Danish Meteorological Institute. The unusual May heat has extended to Scotland, which had its hottest May temperature on record on May 25 at Achnagart: 29.3°C (85°F). Greenland's Narsarsuaq has seen a string of 3 consecutive days over 70°F this week--the 3rd, 7th, and 12th warmest days there since record keeping began in 1941. The ridge of high pressure responsible is expected to stay in place several more days, bringing additional 70° days over Southern Greenland. The warm May temperatures could be setting the stage for a big Greenland melt season this summer--the International Research Institute for Climate and Society (IRI) is predicting a 50 - 60% that the southern 2/3 of Greenland will experience above-average temperatures this summer. They forecast just a 10 - 15% chance of below-average temperatures.

Why Greenland is important
If the massive icecap on Greenland were to melt, global sea level would rise 7 meters (23 ft). Temperatures in Greenland are predicted to rise 3°C by 2100, to levels similar to those present during that warm period 120,000 years ago. During that period, roughly half of the Greenland ice sheet melted, increasing sea level by 2.2 - 3.4 meters (7.2 - 11.2 ft.) However, the 2007 IPCC report expects melting of the Greenland ice sheet to occur over about a 1,000 year period, delaying much of the expected sea level rise for many centuries. While Greenland's ice isn't going to be melting completely and catastrophically flooding low-lying areas of the earth in the next few decades (sea level is only rising about 3 mm per year or 1.2 inches per decade at present), the risk later this century needs to be taken seriously. Higher sea levels will cause increased erosion, salt water intrusion, and storm surge damage in coastal areas, in addition to a loss of barrier formations such as islands, sand bars, and reefs that would normally protect coastal zones from battering by waves and wind. Additionally, coastal zones are sites of incredible economic and agricultural activity, which would also be negatively affected by higher sea levels. Currently, melting ice from Greenland is thought to cause about 0.7 mm/year of global sea level rise, which is about 20 - 25% of the global total, according to an international research group led by the GFZ German Research Centre for Geosciences, in an article published the latest issue of Earth and Planetary Science Letters, 1 June 2012. In 2007, the IPCC estimated that Greenland ice melt was responsible for only 10 - 15% of the total global sea level rise. Ice loss in Greenland is accelerating, and if current ice loss trends continue for the next ten years, Greenland's contribution to sea level rise will double to 1.4 mm/yr by 2022. The increased ice loss in Greenland is being driven by a combination of warmer air temperatures, warmer ocean temperatures, and loss of Arctic sea ice. Ocean temperatures surrounding Southern Greenland have increased by 1 - 2°C since 1990 (figure at right.)

Each small + symbol is a monthly value. Between 2003 - 2009, Greenland lost an average of 250 gigatons of ice per year. In 2011, the loss was 70% greater than that. Image credit: Arctic Report Card
Update on the 2011 Greenland melt season
According to the 2011 Arctic Report Card, it was another very warm year in Greenland in 2011, which led to substantial melting of the ice. Here are some of the highlights from the report:
1) The area and duration of melting at the surface of the Greenland ice sheet in summer 2011 were the third highest since 1979.
2) Increased surface melting and below average summer snowfall in recent years has made the icecap steadily darker. In 2011, the icecap had the lowest reflectivity (albedo) of any year since satellite measurements of reflectivity began in 2000.
3) The area of glaciers that empty into the sea continued to decrease, though at less than half the rate of the previous 10 years.
4) Total ice sheet mass loss in 2011 was 70% larger than the 2003 - 2009 average annual loss rate of -250 gigatons per year. According to satellite gravity data obtained since 2002, ice sheet mass loss is accelerating.

Don't ruin our fun. We want it to be perpetual. :(
136 PlazaRed: Adding trees is good.
Replanting them may not be good!
I am all in favour of planting new trees where there are none at the moment.
The reason for my comment using a quoted reference was to emphasize the possible error of going headlong into replanting.
Managed planting and replanting of trees often leads to the destruction of most if not all of the other ground plants which in themselves take up large amounts of CO2. This has been shown to have happened in parts of the Amazon rainforest. Pine plantations are another example.
A return to natural vegetation of areas would seem a more useful long term approach.
The end results of some tree planting and replanting may be less CO2 being taken up by the trees than allready is by the present vegetation.
Yep, old growth forests are over twice as efficient as tree plantations at converting CO2 and sunlight into biomass. And even more so because organic debris produced in old forests is converted with high efficiency into detrivores including saprophytic plants that have low need for sunlight as well as fungi such as mushrooms that store the main of their bodies underground or within rotting trunks.
Even a natural meadow is more efficient than tree plantations or other agricultural uses.
It's nice to talk about planting ornamental trees, but for most of the time of their existence, nearly-all-to-most of the available sunlight is hitting the ground. Ornamental trees are unlikely to ever have anywhere near the sunlight&CO2 biomass-production efficiency as even an old orchard.
And again, the ground beneath ornamental trees is unlikely to have even half the sunlight&CO2-to-biomass production efficiency as a natural meadow, or near that of old orchards for that matter, let alone the natural undergrowth of old forests.
Yes, your highness
They might have to be severe systems just in order to bring some rain.
Moisture is getting really high so expect high rainfall rates 2 inches an hour with average cells and 3 to 5 inch per hour with strong cores, just like we expect heading into June.
Lol
Watch the radar, its looking pretty good, I'm not ensuring anything till it really starts pouring around here, but it looks good overnight.
Looks somewhat impressive, but to be honest I prefer the big daytime heating thunderstorms.
...and who had this?
Lol
Something that I don't see addressed is the amount of carbon sequestered by root systems. Some trees have as much mass underneath the ground as above it.
If you're farming a fast growing species which might be harvested in 20 years then you might be sticking a lot more carbon underground than would happen by letting a forest 'go old'. Each generation is going to create a new set of carbon-bearing roots.
Thank you very much for the compliment. It makes it seem like making them is worthwhile. I love making them and appreciate the feedback. I just try to add more useful info to the blog. In fact, last year somebody mentioned that they were showing the graphics to their students to explain what was going on in the tropics (maybe during Irene?). I don't remember who it was, though.
Keeper....
Yer killin' me. Don't know if you'll see this post, but...
I've watched the countdown to today and now I'll watch the next countdown....
Lindy
Congrats. That's quite an accolade.
Have a great night!
Sequestering carbon ten feet underground is not really productive, in my humble opinion. You don't happen to work for the timber industry do you?
Why do you ask?
No, the (what are now multiple) continents were closer to the equator. The mostly floating ice-sheets at the poles would have experienced strong yearly melting from below; severely limiting their maximum semi-permanent size.
And no again...
...even the highest CO2 level on the chart you provided is only ~17 of times that of presentday levels. And the margin of error is HUGE at that point: coulda been closer to 8times that of today.
1) CO2 levels do not have a 1-to-1 correspondence with the amount of greenhousing. Every doubling of CO2-level increases the temperature by ~3degreesCelsius. The Cambrian Greenhouse effect of 8-to-17 times the presentday CO2 level would produce a maximum* 9degreesC to (a wee-bit-over) 12degreesC of increase.
2) The Sun does evolve noticeably in half a billion years. eg It'll be so much hotter in 500million years that Earth's presentday multicellular life could no longer exist... except for some thermophiles.
The Sun was cooler -- producing less light energy -- 500million years ago than it is now. Meaning that the natural blackbody temperature of an object orbiting at Earth's distance would have been colder.
3) So that extra 9-to-12degreesC from greenhousing would have been added to an Earth that would have been colder from that lower amount of direct sunlight alone.
* Actually less: the higher the concentration of any particular greenhouse gas, the closer to spectrum saturation it is inregard to reflecting the particular InfraRed(heat)frequencies that the gas interacts with.
Kinda like silvered glass. The thicker the silver layer, the more sunlight it reflects and the less it allows into the building. (Think two-way mirrors.) Thick enough, and (close enough to) 100% of the visible sunlight is reflected and no visible sunlight enters the building.
Increasing the thickness past that point doesn't increase the reflectivity. Similarly, increasing the CO2 concentration past a certain level fails to produce any noticeable greenhousing increase.

FORECASTER BERG
Root rot. The evolutionary advantage goes to the species that allows its roots to decay into nutrients that'll feed the next generation.
Consider caribou/reindeer. The males drop their antlers, while the females do not. The primary limiting factor to growth in most tundra, grassland, and forest environments is calcium.
Dropping the antlers makes the male more vulnerable to predation. BUT it also makes it possible for vegetation and smaller animals to gain the calcium needed to achieve their own reproductive success.
Predators want the least hassle possible in obtaining their next meal: hunting injuries are expensive both metabolicly and reproductively. Even a mountain lion tends to choose mice and other small critters over big game.
So becoming more vulnerable while ensuring reproductive success of smaller mammals (and birds and lizards and etc) also ensures the successful reproduction of the caribou gene line by the still antlered (and pregnant) female caribou AND later survival of their offspring by providing "easy pickin's" for predators.
I couldn't agree more.
Though it is highly likely that it won't, it sure looks like it bodes watching when i gets over water.
I've got to admit that your comment makes no sense to me.
Are you saying that after the first generation of trees subsequent generations use that root-stored carbon rather than CO2 from the atmosphere?

Nope. Though the increased CO2 level from rotting might also have a small effect on growth rate, the amount of CO2 already in the air is more than enough.
The limiting factors to growth&reproduction are other minerals and nutrients. And trees store a lot of those minerals and nutrients in their roots. Rotting releases those nutrients in a highly digestible form.
To new trees, the cellulose decay into (mostly) CO2 and methane is just a not-particularly useful side-effect of the nutrient release process. Following rotted rootlines is probably easier and might be "smarter" than driving a new rootline through fresh soil and rock.
What might work sequestration-wise is harvesting the lumber, air-drying it, then turning it into charcoal. Use the flamable volatile gases produced during charcoal-production to heat the lumber to turn it into charcoal. Then stuff the charcoal into coal-mines/etc.
Of course it'd make a lot more sense to not mine the fossil-fuels in the first place -- coal and tar-sands/shale are especially dirty energy producers -- and use the charcoal*gases for energy production (along with charcoal-to-coke directly for industrial processes that need coke).
Foreseeable problem is that the remnant charcoal would also contain elements necessary for life such as sodium, magnesium, potassium, calcium, phosphorus, etc. And I think that the coking process (that'd release those life elements) uses too much energy to allow justification of coke burial.
* LOTs of other organic volatiles in charcoal-gas than the hydrogen, methane, and carbon monoxide produced by the coal-gas process.
Up in the land of cariboo there is scant soil, just a sponge of moss on top of rock usually; it's a hole different world of nutrient storage.
It's late, I'm tired, let me take a quick shot at this...
Trees can have 40% to 50% of their total mass below ground. Those roots are mostly carbon which is pulled out of the atmosphere in the form of CO2.
If you let a tree reach some decent size, cut it down, replant another, then you will sequester another "40%" worth of carbon. Cut and replant - another "40%".
Each growth cycle sequesters more carbon.
Additionally, growing trees absorb more CO2 than do mature trees.
The rotting cellulose of old trees which releases carbon back into the cycle is mainly the portion of the tree/plant which is above ground. Not the root structure.
The rotting structure below ground releases nutrients but (I think) little if any carbon is taken in by roots.
Point is, biomass is likely a carbon negative fuel. Growing trees (or switchgrass, for example) pulls CO2 from the atmosphere and returns less when burned for fuel.
Unless I've got my biology wrong....

I could be wrong
Oh, and I do know that trees store their extra minerals&nutrients in their root systems. eg Before leaf fall, most of a leaf's crucial minerals&nutrients are transfered to the root system: that transfer being what (near)kills the leaf and weakens its connection to its supporting twig, allowing the leaves to fall.
Anyways ladies and gents, without further ado, let's get right down to the nitty gritty:
------------------------------------------------- ----
Tropical Storm Alberto
AL012012
19 May - 22 May
Alberto was an out of season tropical storm, the first of two, that developed in the month of May in the north Atlantic. Alberto did not affect land.
a. Storm history
Alberto's origins appear to have begun as early as 10 May. During this time, satellite and water vapor imagery images showed that a well-defined upper-tropospheric cold low, accompanied by a well-marked cold front, entered west Texas. The front entered the Gulf of Mexico early on 12 May. Although the front gradually decayed, it became quasi-stationary over the central Gulf of Mexico, possibly in response to being sandwiched between two high pressure areas. During this time, the front produced intermittent clusters of showers and thunderstorms. The preexisting large-scale cyclonic flow was reinforced in this area by the passage of several shortwave perturbations in the semipermanent mid-latitude pressure belt. The associated cloudiness moved across the Florida peninsula, and entered the western Atlantic on 16 May. The activity moved steadily northeastward and soon became entangled with an approaching trough.
The southern portion of this activity became stationary over the western Atlantic waters, while the northern portion of the trough continued moving northward. Around 1200 UTC 17 May, satellite and radar animations showed that a cloud mass formed over central South Carolina, possibly associated with a weak mesoscale convective system (MCS). This system moved offshore shortly after 0000 UTC 18 May, and later ASCAT data indicated the presence of a small surface circulation. The small low continued to become better organized, and it is estimated that a tropical depression formed from it around 1200 UTC 18 May, while centered about 100 miles south of Cape Fear, North Carolina. The "best track" of the cyclone (listed below) begins at this time. Other coordinates, including six-hourly position, pressure, and intensity estimates, respectively, are also given.
The depression became a tropical storm about 6 hr later. Initially, Alberto was embedded in a region of weak steering currents, and drifted slowly southwest. Based on a nearby ship report, the cyclone reached its estimated peak intensity of 50 kt around 2100 UTC. Soon thereafter, the tropical storm began to weaken under increasing southwesterly shear. In addition, water vapor imagery during this time suggests that Alberto was ingesting a very dry airmass over the southeastern United States, which likely counteracted the otherwise favorable sea surface temperature regime of the Gulf Stream. Synoptic steering currents gradually became more defined as a weak upper-level trough moved through the Ohio Valley, and Alberto responded with a gradual turn to the south and southeast, on a track well offshore the southeastern United States coast.
Continuously battered by marginal atmospheric and thermodynamic parameters -- namely dry air and wind shear, Alberto weakened to a tropical depression near 0000 UTC 22 May. At that time, the center became almost completely exposed to the west of a diminishing area of showers. Convection subsequently increased, but this activity was disorganized, and is not assumed to have been sufficient to bring Alberto back to a tropical storm. Later that day, around 1200 UTC, the cyclone became a remnant low while located approximately 160 miles southeast of Cape Hatteras, North Carolina. Moving northeastward, the remnant low lost its identity within a broad and nearly-stationary trough that extended from the northwestern Caribbean Sea to Bermuda. This same trough would soon assist in the formation of Tropical Storm Beryl.
