Cyclonic Activity persists in Arctic

Above image, edited from Naval Research Laboratory, shows that a large area has developed at the center of the Arctic Ocean with very thin ice, at some places down to virtually zero, i.e. open water.

This development is to a large extent caused by persistent cyclonic activity in the Arctic. The Arctic is warming up faster than anywhere else, and this is reducing the temperature difference between the Arctic and lower latitudes. As a result, the polar vortex and jet stream get distorted, resulting in extreme weather. This is graphically illustrated by the animation below, from the California Regional Weather Server.

The Threat of Wildfires in the North

NASA/NOAA image based on Suomi NPP satellite data from April 2012 to April 2013, with grid added

A new map has been issued by NOAA/NASA. The map shows that most vegetation grows in two bands, i.e. the Tropical Band (between latitudes 15°N and 15°S) and the Northern Band in between 45°N and 75°N, i.e. in North America, Europe and Siberia. On above image, the map is roughly overlayed with a grid to indicate latitude and longitude co-ordinates.

Vegetation in the Northern Band extends beyond the Arctic Circle (latitude 66° 33′ 44″ or 66.5622°, in blue on above image from Arcticsystem.no) into the Arctic, covering sparsely-populated areas such in Siberia, Alaska and the northern parts of Canada and Scandinavia. Further into the Arctic, there are huge areas with bush and shrubland that have taken thousands of years to develop, and once burnt, it can take a long time for vegetation to return, due to the short growing season and harsh conditions in the Arctic.

Above map with soil carbon content further shows that the top 100 cm of soil in the northern circumpolar region furthermore contains huge amounts of carbon.

May 16 2013 Drought 90 days Arctic

Global warming increases the risk of wildfires. This is especially applicable to the Arctic, where temperatures have been rising faster than anywhere else on Earth. Anomalies can be very high in specific cases, as illustrated by the temperature map below. High temperatures and drought combine to increase the threat of wildfires (see above image showing drought severity).

June 25, 2013 from Wunderground.com - Moscow broke its more than 100-year-old record for the hottest June 27

Zyryanka, Siberia, recently recorded a high of 37.4°C (99.3°F), against normal high temperatures of 20°C to 21°C for this time of year. Heat wave conditions were also recorded in Alaska recently, with temperatures as high as 96°F (36°C).

On June 19, 2013, NASA captured this image of smoke from wildfires burning in western Alaska. The smoke was moving west over Norton Sound. (The center of the image is roughly 163° West and 62° North.) Red outlines indicate hot spots with unusually warm surface temperatures associated with fire.

Siberian wildfires June 21, from RobertScribbler 

from methanetracker.org

Wildfires raged in Russia in 2010. Flames ravaged 1.25 million hectares (4,826 mi²) of land including 2,092 hectares of peat moor. Damage from the fires is estimated to be $15 billion, in a report in the Guardian. Cost of fire-fighting efforts and agricultural losses alone are estimated at over $2bn, reports Munich Re, adding that Moscow's inhabitants suffered under a dense cloud of smoke which enveloped the city. In addition to toxic gases, it also contained considerable amounts of particulate matter. Mortality increased significantly: the number of deaths in July and August was 56,000 higher than in the same months in 2009.  [From: Abrupt Local Warming, May 16, 2012]

Wildfires in the North threaten to cause large emissions of greenhouse gases and soot, which can settle on snow and ice in the Arctic and the Himalayan Plateau, with the resulting albedo changes causing a lot more sunlight to be absorbed, instead of reflected as was the case earlier. This in turn adds to the problem. Additionally, rising temperatures in the Arctic threaten to cause release of huge amounts of methane from sediments below the Arctic Ocean. This situation threatens to escalate into runway global warming in a matter of years, as illustrated by the image below.

How much will temperatures rise?

In conclusion, the risk is unacceptable and calls for a comprehensive and effective action plan that executes multiple lines of action in parallel, such as the 3-part Climate Action Plan below. Part 1 calls for a sustainable economy, i.e. dramatic reductions of pollutants on land, in oceans and in the atmosphere. Part 2 calls for heat management. Part 3 calls for methane management and further measures.

The Climate Action Plan set out in above diagram can be initiated immediately in any country, without the need for an international agreement to be reached first. This can avoid delays associated with complicated negotiations and on-going verification of implementation and progress in other nations.

In nations with both federal and state governments, such as the United States of America, the Climate Action Plan could be implemented as follows:

• The President directs federal departments and agencies to reduce their emissions for each type of pollutant annually by a set percentage, say, CO2 and CH4 by 10%, and HFCs, N2O and soot by higher percentages.
• The President demands states to each make the same cuts. 
• The President directs the federal Environmental Protection Agency (EPA) to monitor implementation of states and to act step in where a state looks set to fail to miss one or more targets, by imposing (federal) fees on applicable polluting products sold in the respective state, with revenues used for federal benefits.

Such federal benefits could include building interstate High-Speed Rail tracks, adaptation and conservation measures, management of national parks, R&D into batteries, ways to vegetate deserts and other land use measurements, all at the discretion of the EPA. The fees can be roughly calculated as the average of fees that other states impose in successful efforts to meet their targets.

This way, the decision how to reduce targets is largely delegated to state level, while states can similarly delegate decisions to local communities. While feebates, preferably implemented locally, are recommended as the most effective way to reach targets, each state and even each local community can largely decide how to implement things, provided that each of the targets are reached.

Similar targets could be adopted elsewhere in the world, and each nation could similarly delegate responsibilities to local communities. Additionally, it makes sense to agree internationally to impose extra fees on international commercial aviation, with revenues used to develop ways to cool the Arctic.

First IAF C-17 Arrives At Indian Base

The Indian Air Force (IAF) has contracted for ten C-17 airlifters for $4.12 billion, which will make the IAF the largest C-17 operator other than the US Air Force which operates 224 of these airlifters. Boeing is required to deliver the first five C-17s this year, and the remaining five in 2014.

The IAF is pushing for an additional six C-17s, which would provide a lifeline to the C-17 production line at Long Beach, California, which creates some 5000 jobs at Long Beach and another 17,000 elsewhere in the US. According to current plans that line will be shut down by end-2014 after building India’s ten C-17s and the US Air Force’s last seven aircraft.

Open Water In Areas Around North Pole

In some areas around the North Pole, thickness of the sea ice has declined to virtually zero, i.e. open water.

What could have caused this open water? Let's go through some of the background.

North Hemisphere snow cover has been low for some time. Snow cover in May 2013 was the lowest on record for Eurasia. There now is very little snow left, as shown on the image right, adapted from the National Ice Center.

Low snow cover is causing more sunlight to be absorbed, rather than reflected back into space. As can be expected, there now are high surface temperatures in many areas, as illustrated by the NOAA image below. Anomalies can be very high in specific cases. Zyryanka, Siberia, recently recorded a high of 37.4 C, against normal high temperatures of 20 C to 21 C for this time of year. Heat wave conditions were also recorded in Alaska recently (satellite image of Alaska below).

NASA image June 17, 2013, credit: NASA/Jeff Schmaltz, LANCE MODIS Rapid Response Team, NASA GSFC - from caption by Adam Voiland: "Talkeetna, a town about 100 miles north of Anchorage, saw temperatures reach 96°F (36°C) on June 17. Other towns in southern Alaska set all-time record highs, including Cordova, Valez, and Seward. The high temperatures also helped fuel wildfires and hastened the breakup of sea ice in the Chukchi Sea."

Accordingly, a large amount of relatively warm water from rivers has flowed into the Arctic Ocean, in addition to warm water from the Atlantic and Pacific Oceans.

Sea surface temperatures have been anomalously high in many places around the edges of the sea ice, as also shown on the NOAA image below.

Nonetheless, as the above images also make clear, sea surface temperatures closer to the North Pole have until now remained at or below zero degrees Celsius, with sea ice cover appearing to remain in place. The webcam below from the North Pole Environmental Observatory shows that there still is a lot of ice, at least in some parts around the North Pole.

So, what could have caused the sea ice to experience such a dramatic thickness decline in some areas close to the North Pole?

Firstly, as discussed in earlier posts, there has been strong cyclonic activity over the Arctic Ocean (see also Arctic Sea Ice blog post). This has made the sea ice more prone and vulnerable to the rapid decline that is now taking place in many areas.

Furthermore, Arctic sea ice thickness is very low, as illustrated by the image below.

Arctic sea ice volume/extent ratio, adapted by Sam Carana from an image by Neven (click to enlarge)

Finally, there has been a lot of sunshine at the North Pole. At this time of year, insolation in the Arctic is at its highest. Solstice (June 20 or June 21, 2013, depending on time zone) is the day when the Arctic receives the most hours of sunlight, as Earth reaches its maximum axial tilt toward the sun of 23° 26'. In fact, insolation during the months June and July is higher in the Arctic than anywhere else on Earth, as shown on the image below.

Monthly insolation for selected latitudes -  adapted from Pidwirny, M. (2006), in "Earth-Sun Relationships and Insolation",  Fundamentals of Physical Geography, 2nd Edition. 

In conclusion, the current rapid sea ice thickness decline close to the North Pole is mostly due to a combination of earlier cyclonic activity and lots of sunlight, while the sea ice was already very thin to start with. The cyclone broke up the sea ice at the center of the Arctic Ocean, which is turn made it more prone to melting rapidly. The cyclone did more, though, as contributor to the Arctic-news blog Veli Albert Kallio explains:

"The ocean surface freezes if the temperature falls below -2.5C. The reason for the negative melting point is the presence of 4-5% of sea salt. Only in the polar regions does the sea surface cool sufficiently for sea ice to form during winters.

The sea ice cover is currently thinning near the North Pole between 80-90 degrees north. This part of the ocean is very deep. It receives heat of the Gulf Stream from the south: as the warm water vapourises, its salt content to water increases. This densifies the Gulf Stream which then falls onto the sea floor where it dissipates its heat to the overlying water column. The deep basin of the Arctic Ocean is now getting sufficiently warmed for the thin sea ice cover to thin on top of it. The transportation of heat to the icy surface is combined with the winds that push cold surface water down while rising heat to surface."

Indeed, vertical mixing of the water column was enhanced due to cyclonic activity, and this occurred especially in the parts of the Arctic Ocean that also are the deepest, as illustrated by the animation below.

The compilation of images below shows how the decline of sea ice has taken place in a matter of weeks.

This spells bad news for the future. It confirms earlier analyses (see links below) that the sea ice will disappear altogether within years. It shows that the sea ice is capable of breaking up abruptly, not only at the outer edges, but also at the center of the Arctic Ocean. As the Arctic sea ice keeps declining in thickness, it does indeed look set to break up and disappear abruptly across most of the Arctic Ocean within a few years. Models that are based on sea ice merely shrinking slowly from the outer edges inward should reconsider their projections accordingly.

Extreme weather becomes the norm - what can you do?

. . a sky that has turned red due to greenhouse gases, while the land is flooded. The handful of
people who survived are standing by helplessly on higher grounds, in despair and without hope,
while one figure turns to me in panic and pain, uttering nothing but a silent scream . . .
(comment by Sam Carana, March 8, 2012, on auction of the Scream, by Edvard Munch)

Symptoms

Torrential rains in some regions are causing massive floods while in other locales record droughts are occurring with higher frequency and severity and areal extent around the globe. Global food production is being hit hard, leading to large price increases and political instability. Areas under drought are experiencing numerous massive forest fires of incredible ferocity.

Causes

The statistics of extreme weather events have changed for the worst due to changes in the location, speed, and waviness of the jet streams which guide weather patterns and separate cold and dry northern air from warm and moist southern air. The jet streams have changed since the equator to north-pole temperature difference has decreased due to the huge temperature rise in the Arctic.

The huge temperature rise in the Arctic is due to a collapse in the area of highly reflective snow and ice, which is caused by melting. The melting is from warming from the increase of greenhouse gases from fossil fuel burning. The Arctic sea ice and spring snow cover will vanish within a few years and the weather extremes will increase at least 10x.

What can you do?

Go talk to you politicians and friends about climate change and the need to slash fossil fuel emissions. Immediately. Cut and paste my comments above and post them on facebook, send them to newspapers, and educate yourself on the science behind all the above linkages. Leave my name on or take it off and plagiarize all you want, just get this knowledge out there...

Mean Methane Levels reach 1800 ppb

On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. This is 120 ppm higher than pre-industrial peak levels. This unfortunate milestone was widely reported in the media.

There's another milestone that looks even more threatening than the above one. On the morning of June 16, 2013, methane levels reached an average mean of 1800 parts per billion (ppb). This is more than 1100 ppb higher than levels reached in pre-industrial times (see graph further below).

NOAA image

Vostok ice core analysis shows that temperatures and levels of carbon dioxide and methane have all moved within narrow bands while remaining in sync with each other over the past 400,000 years. Carbon dioxide moved within a band with lower and upper boundaries of respectively 200 and 280 ppm. Methane moved within lower and upper boundaries of respectively 400 and 800 ppb.
Temperatures moved within lower and upper boundaries of respectively -8 and 2 degrees Celsius.

From a historic perspective, greenhouse gas levels have risen abruptly to unprecedented levels. While already at a historic peak, humans have caused emissions of additional greenhouse gases. There's no doubt that such greenhouse gas levels will lead to huge rises in temperatures. The question is how long it will take for temperatures to catch up and rise.

Below is another way of looking at the hockey stick. And of course, further emissions could be added as well, such as nitrous oxide and soot.

Large releases of methane must have taken place numerous times in history, as evidenced by numerous pockmarks, as large as 11 km (6.8 mi) wide.

Importantly, large methane releases in the past did not result in runaway global warming for a number of reasons:

• methane release typically took place gradually over many years, each time allowing a large release of methane to be broken down naturally over the years before another one occurred. 
• Where high levels of methane in the atmosphere persisted and caused a lot of heat to be trapped, this heat could still be coped with due to greater presence of ice acting as a buffer and consuming the heat before it could escalate into runaway temperature rises.

Wikipedia image

Veli Albert Kallio comments:

The problem with ice cores is that if there is too sudden methane surge, then the climate warms very rapidly. This then results the glacier surfaces melting away and the ice core begins to loose regressively surface data if there is too much methane in the air.

Because of this, there has been previous occurrences of high methane, and these were instrumental to bring the ice ages ice sheets to end (Euan Nisbet's Royal Society paper). The key to this is to look at some key anomalies and devise the right experiments to test the hypothesis for methane eruptions as the period to ice ages.

Thus, the current methane melting and 1800 ppm rise is nothing new except that there are no huge Pleistocene glaciers to cool the Arctic Ocean if methane goes to overdrive this time. In fact methane may have been many times higher than that but all surface ice kept melting away and staying regressive until cold water and ice from destabilised ice sheets stopped the supply of methane (it decays fast if supply is cut and temperatures fall back rapidly when seas rose).

The Laurentide Ice Sheet alone was equivalent of 25 Greenland Ice Sheets and the Weischelian and other sheets on top of that. So, the glaciers do not act the same way as fireman to extinguish methane. Runaway global warming is now possibility if the Arctic loses its methane holding capability due to warming.

Further discussion is invited on the following points:

• The large carbon-12 emission anomalies in East Asian historical objects that are dateable by historical knowledge. Discussion about the explanations concocted and why methane emission from permafrost soils and sea beds must be the answer; 

• the much overlooked fact that if there were ever very highly elevated concentrations of air in the Arctic, this would induce strong melting of glaciers which then lack those surface depositions where the air were most CH4 and CO2 laden. Even moderate levels of temperature rise damaged Larsen A, Larsen B, Petermann and Ellesmere glaciers. If huge runaway outgassing came out when Beringia flipped into soil warming, then methane came out really large amounts with CO2.

• Discussion of the experiments how to compensate for the possible lack of "time" in methane elevated periods in the ice cores by alternative experiments to obtain daily, weekly, monthly and yearly emission rates of CH4 and CO2 from the Last Glacial Maximum to the Holocene Thermal Maximum (as daily, weekly, monthly, and yearly sampling of air).

Editor's update: Methane levels go up and down with the seasons, and differ by altitude. As above post shows, mean levels reached 1800 ppb in May 2013 at 586 mb, according to MetOp-2 data. Note that IPCC AR5 gives levels of 1798 ppb in 2010 and 1803 ppb in 2011, as further discussed in later posts such as this one. Also, see historic data as supplied by NOAA below.

Arctic Sea Ice September 2013 Projections

What will the Arctic Sea Ice look like in September 2013?

Several projections for Arctic sea ice extent are being discussed at places such as ARCUS (Arctic Research Consortium of the United States) and the Arctic Sea Ice Blog. The image below, from ARCUS, shows various projections of September 2013 arctic sea extent (defined as the monthly average for September) with a median value of 4.1 million square kilometers, with quartiles of 3.8 and 4.4 million square kilometers.

Note that sea ice extent in the above projections is defined as area of ocean with at least 15% ice, in line with the way the NSIDC calculates extent. By contrast, the Danish Meteorological Institute includes areas with ice concentration higher than 30% to calculate ice extent.

Rather than looking at the projected average for September, one could also project the minimum value for September 2013. And rather than looking at sea ice extent, one could also look at sea ice area, which differs from sea ice extent as the NSIDC FAQ page describes:

A simplified way to think of extent versus area is to imagine a slice of Swiss cheese. Extent would be a measure of the edges of the slice of cheese and all of the space inside it. Area would be the measure of where there is cheese only, not including the holes. That is why if you compare extent and area in the same time period, extent is always bigger.

Above image shows Sam Carana's projected minimum area of 2 million square km for 2013, based on data by Cryosphere Today and on numerous factors, such as continued warming of the water underneath the ice, stronger cyclones, etc.

Roughly in line with above image, by Wipneus, Sam Carana's projection for Arctic sea ice minimum volume is 2,000 cubic km in September 2013.

Readers are invited to submit comments below with further projections.

Arctic sea ice thickness falls by 2m in 21 days in some areas

For years, warnings have been raised about the dramatic decline of Arctic sea ice. Various posts at this blog have also analyzed the exponential nature of the decline in summer sea ice volume and the many feedbacks that fuel this decline. And for years, the conclusion has been that - without action - the sea ice looks set to disappear altogether within years.

Yet, many are still ignoring this warning, often with remarks such as "some of the ice is 5 meters thick; it would take decades for all that ice to melt!" Thick ice does indeed pile up along the northern coast of Greenland and Ellesmere Island, due to the way the ice drifts. This has lead some to argue that an S-shaped curve (sigmoid or gompertz trendline) was more appropriate, with the decline in sea ice volume slowing down as it approaches zero.

However, this argument doesn't seem make much sense, since such a S-shaped trendline would only apply to a relatively small area with very thick sea ice. Exponential curves would still remain the best fit to predict the decline of the sea ice in the Arctic Ocean at large.

Moreover, is it really more appropriate to say that summer sea ice looks set to virtually disappear within years, with just a tiny sliver of ice remaining north of Greenland and Ellesmere Island, instead of saying that the sea ice looks set to disappear altogether within years? How persistent will such a sliver really be?

One of the feedbacks of sea ice decline is that, as the decline progresses, cyclones can be expected to hit the remaining sea ice ever harder. How much damage can such cyclones and further feedbacks do? A previous post describes thin spots developing in the sea ice under the influence of a cyclone. The image below shows areas at the center of the Arctic Ocean (large circle) where thickness of the sea ice fell from 2 meters to 1 meters over a period of 21 days. Furthermore, the image below also shows that, over this period, 5m-thick ice was reduced to 3-meters thickness (top small circle), while 2m-thick ice was reduced to zero (bottom small circle).

2m falls in thickness in 21 days - click on image to enlarge

In conclusion, without action the Arctic sea ice looks set to continue to decline exponentially, while strong feedbacks such as cyclones developing when there is more open water, look set to add to the decline and cause the Arctic sea ice to disappear completely within years. For an overview of lines of action, see this post at the methane hydrates blog.

SOCOM Wants Iron-Man Suits for the A Teams

The US Special Operations Command is looking for revolutionary new gear assisting troops in exceeding human performance in combat. The idea sounds similar to a science fiction tale, but if the command will be successful in its quest – this time it may be real. The command has posted a request for information (RFI) to government research centers, academy and industry, to provide information that could contribute to the evolution of the Tactical Assault Light Operator Suit, or TALOS.

 The kit will be applied as part of a futuristic uniform suit, using powered exoskeleton providing the wearer superhuman strength or ultra protection with full-body ballistic armor. Using wide-area networking, wearable computers and antennae, operators will have more situational awareness, through bionic visual and aural sensing. Other technologies that could be implemented include non-visual means of information display, including the utilization of cognitive thoughts and immersive displays depicting personalized information over the surrounding environment. health and medical monitoring features could employ embedded monitoring, oxygen supply systems, wound stasis and electromechanical compensation. Thermal and Energy generation and management are also likely to be explored.


SOCOM issued the RFI on the US Government Federal Opportunity Bulletin board, and is expecting submissions by June 15. The command expects submissions of technologies already in development (TRL 5 or higher) that could be demonstrated in a short term. As much as this vision seems futuristic, SOCOM is looking for practical, near-term capabilities. typical of the command’s no nonsense attitude, the technologies selected for demonstrations should be integrated to form an initial capability within twelve months. A secondary goal is to determine the feasibility of fielding objective capabilities within three years. Such technologies could be submitted by research and development organizations, private industry, government labs and academia as well as individuals.
One of the responders is the U.S. Army Research, Development and Engineering Command (RDECOM), is one of the government establishments that have responded to the call. “There is no one industry that can build it,” said SOCOM Senior Enlisted Advisor Command Sgt. Maj. Chris Faris during a panel discussion at a conference at MacDill Air Force Base, Fla. The demonstrations of relevant technologies would take place a month later, on July 8-10, in Florida.

TALOS will have a physiological subsystem that lies against the skin that is embedded with sensors to monitor core body temperature, skin temperature, heart rate, body position and hydration levels. The body armor could consist of magnetorheological fluids – also known as ‘liquid body armor’ – that transforms from liquid to solid in milliseconds when a magnetic field or electrical current is applied. Though still in development, this technology will likely be submitted to support TALOS.
“[The] requirement is a comprehensive family of systems in a combat armor suit where we bring together an exoskeleton with innovative armor, displays for power monitoring, health monitoring, and integrating a weapon into that – a whole bunch of stuff that RDECOM is playing heavily in,” said. Lt. Col. Karl Borjes, an RDECOM science advisor assigned to SOCOM. “RDECOM cuts across every aspect making up this combat armor suit,” Borjes said “It’s advanced armor. It’s communications, antennas. It’s cognitive performance. It’s sensors, miniature-type circuits. That’s all going to fit in here, too.”

One of the programs that could be considered for this quest is ‘Warrior Web’, an exoskeleton capability currently managed by the Defense Advanced Research Agency (DARPA) and the U.S. Army, exploring a new kit enabling soldiers to reduce fatigue and potential injuries caused by excessive loads they carry on dismounted operations. DARPA’s Warrior Web is a soft, lightweight under-suit that will augment the work of the Soldiers’ own muscles, to significantly boosting endurance, carrying capacity and overall warfighter effectiveness–all while using no more than 100 Watts of electrical power.

The Warrior Web program consists of two related program tasks – the first task currently underway aims to develop a mix of core ‘critical technologies’, deemed criticalCurrently underway, Task A seeks to develop a mix of core technologies deemed critical for the program’s success. On the second phase, scheduled to commence in fall 2013 researchers will develop and fabricate an integrated suit that would eventually undergo real-world testing to evaluate its performance.
A prototype suit is already undergoing testing at the U.S. Army Research Laboratory Human Research and Engineering Directorate (ARL HRED), evaluating various prototype devices. The testing evaluates how each prototype incorporates different technologies and approaches to reduce forces on the body, decrease fatigue, stabilize joints and help Soldiers to maintain a natural gait under a heavy load. The testing uses a multi-camera motion-capture system to determine any changes in gait or balance, a cardio-pulmonary exercise testing device to measure oxygen consumption and a variety of sensors to collect force, acceleration and muscle activity data.
