Large Falls in Arctic Sea Ice Thickness over May 2014

Comparing ice thickness (in meters) on May 2, 2014 (left) and May 30, 2014 (right, forecast run May 25, 2014)
Arctic sea ice has shown large falls in thickness in many areas over the course of May 2014, as shown on above image. The animation below also compares the situation between May 2, 2014, and May 30, 2014 (as forecast by Naval Research Laboratory on May 23, 2014). Ice thickness is in meters.


Thickness is an important indicator of the vulnerability of the ice. If only looking at sea ice extent, one might (wrongly) conclude that sea ice retreat was only minor and that everything looked fine. By contrast, when looking at thickness, it becomes evident that large falls have occurred over the course of May 2014.

Falls at the edges of the sea ice can be expected at this time of the year, but the large fall closer to the center is frightening. On the one hand, it appears to reflect cyclonic weather and subsequent drift of the ice. On the other hand, it also indicates how vulnerable the sea ice has become. Last year, a large area showed up at the center of the sea ice where the ice became very thin, as discussed in July 2013 in the post Open Water at North Pole and again in the September 2013 post North Hole.

The appearance of huge weak areas at the center of the sea ice adds to its vulnerability and increases the prospect of total sea ice collapse, in case of one or more large cyclones hitting the Arctic Ocean later this year. To highlight the dangerous situation, the main image from a post earlier this month is again added below.


Adding to the concerns are huge sea surface temperature anomalies, as illustrated by the image below, showing anomalies at May 23, 2014, and created by Harold Hensel with ClimateReanalyzer and Google Earth.

The image below shows sea surface anomalies on May 26, 2014, with an overlay of land temperatures, as created by Harold Hensel and edited by Sam Carana.


The image shows sea surface temperatures on the Northern Hemisphere that are 1.44 degrees Celsius warmer than the baselline temperature, despite large areas with cold water partly resulting from the huge amounts of meltwater flowing down along the edges of Greenland into the North Atlantic Ocean. The graph below shows Northern Hemisphere and Global sea surface temperature anomalies over May 2014.

By comparison, current (May 27, 2014) surface temperature anomalies of 0.64°C globally and 0.84°C for the NH. The image below shows annual temperature anomalies (land and ocean data).



Meanwhile, the development of this year's 'north hole' at the center of the sea ice appears to persist, as illustrated by the image below.

The real budgetary emergency and the myth of "burnable carbon"

by David Spratt


How fast and how profoundly we act to stop climate change caused by human actions, and work to return to a safe climate, is perhaps the greatest challenge our species has ever faced, but are we facing up to what really needs to be done?

We have to come to terms with two key facts: practically speaking, there is no longer a "carbon budget" for burning fossil fuels while still achieving a two-degree Celsius (2°C) future; and the 2°C cap is now known to be dangerously too high.


No Carbon Budget Left - David Spratt from Breakthrough  -  "We have no carbon budget left
for burning of fossils fuels - emergency action is now the only viable path"  - 
David Spratt

For the last two decades, climate policy-making has focused on 2°C of global warming impacts as being manageable, and a target achievable by binding international treaties and incremental, non-disruptive, adjustments to economic incentives and regulations (1).

But former UK government advisor Professor Sir Robert Watson says the idea of a 2°C target "is largely out of the window”, International Energy Agency chief economist Fatih Birol calls it "a nice Utopia", and international negotiations chief Christiana Figueres says we need "a miracle". This is because, in their opinions, emissions will not be reduced sufficiently to keep to the necessary "carbon budget" (2).

The carbon budget has come to public prominence in recent years, including in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report in 2013, as being the difference between the total allowable greenhouse gas emissions for 2°C of warming, and the amount already emitted or spent. The budget varies according to the likelihood of overshooting the target: the higher the risk, the bigger the budget. In the IPCC report, no carbon budget is given for less than a one-in-three chance of failure.

At that one-in-three risk of failure, the IPCC says the total budget is 790 GtC (gigatons, or one billion tons, of carbon), less emissions to 2011 of 515 GtC, leaving a budget of 275 GtC in 2011, or ~245 GtC in 2014 (3).

What is less well understood is that if the risk is low, there is no carbon budget left (4).

Breakthrough National  Climate Restoration
Forum 21-22 June,  Melbourne
Climate change with its non-linear events, tipping points and irreversible events – such as mass extinctions, destruction of ecosystems, the loss of large ice sheets and the triggering of large-scale releases of greenhouse gases from carbon stores such as permafrost and methane clathrates – contains many possibilities for catastrophic failure.

Ian Dunlop, a former senior risk manager and oil and coal industry executive, says the management of catastrophic risk has to be very different from current processes. As serious, irreversible outcomes are likely, this demands very low probabilities of failure: management of catastrophic risk "must centre around contingency planning for high-impact and what were regarded as low-probability events, which unfortunately are now becoming more probable… Major, high-risk industrial operations, such as offshore oil exploration, provide a model, with detailed contingency planning and sequential barriers being put in place to prevent worst-case outcomes" (5).

If a risk-averse (pro-safety) approach is applied – say, of less than 10% probability of exceeding the 2°C target – to carbon budgeting, there is simply no budget available, because it has already been used up. A study from The Centre for Australian Weather and Climate Research shows that "the combination of a 2°C warming target with high probability of success is now unreachable" using the current suite of policy measures, because the budget has expired (6).

This is illustrated in Figure 1 where, as we move to the right (greater probability of meeting target) along the blue line which is the 2°C carbon budget, we reach a point around 90% probability (blue circle) where the total budget intersects with what we have already emitted.



As well, on-going greenhouse emissions associated with food production and deforestation are often conveniently pushed to one side in discussing carbon budgets. UK scientists have shown that if some reasonably optimistic assumptions are made about deforestation and food-related emissions for the rest of the century, then most emission reduction scenarios are incompatible with holding warming to +2ºC, even with a high 50% probability of exceeding the target. In other words, food and deforestation has taken up the remaining budget, leaving no space for fossil fuel emissions (7).

In addition, the carbon budget analysis makes optimistic and risky assumptions about the stability of Arctic, and of polar and other carbon stores such as permafrost. As one example, the modelling discussed in the IPCC report projects an area of summer Arctic sea-ice cover in the year 2100 higher that actually exists at the moment, yet there is a great deal more warming and sea-ice loss to come this century! In fact, many Arctic specialists think the Arctic will be sea-ice free in summer within the next decade, with consequences for global warming that the carbon budget calculations have significantly underestimated. (8)

Australian Climate Council member Prof. Will Steffen says the IPCC carbon budget may "be rather generous". The IPCC report says the modelling used does not include explicit representation of permafrost soil carbon decomposition in response to future warming, and does not consider slow feedbacks associated associated with vegetation changes and ice sheets. Recent research suggests these events could happen well below 2°C of warming, so they should be taken into account, but they are not.

Accounting for the possible release of methane from melting permafrost and ocean sediment implies a substantially lower budget (9). This reinforces the need to take a pro-safety, risk-averse approach to the carbon budget, especially since some research suggests that Arctic permafrost may be vulnerable at less than 2°C or warming (10).

For all these reasons – that is, prudent catastrophic risk management, accounting for food production and deforestation emissions, and for Arctic sea ice and carbon store instability – the idea of "burnable carbon" – that is, how much more coal, gas and oil we can burn and still keep under 2°C – is a dangerous illusion, based on unrealistic, high-risk, assumptions.

A second consideration is that 2°C of warming is not a safe target. Instead, it's the boundary between dangerous and very dangerous (11), and 1°C higher than experienced during the whole period of human civilisation (12), illustrated in Figure 2. The last time greenhouse gas levels were as high as they are today, modern humans did not exist (13), so we are conducting an experiment for which we have no direct observable evidence from our own history, and for which we do not know the full result.



However, we do understand that many major ecosystems will be lost, a 2°C sea-level rise will eventually be measured in the tens of metres (14), and much of human civilisation and large, productive river delta systems will be swamped. There is now evidence to suggest that the current conditions affecting the West Antarctic ice sheet are sufficient to drive between 1.2 and 4 metres of sea rise (15), and evidence that Greenland will contribute more quickly (16), and they are just two contributors to rising sea levels.

It is now clear that the incremental-adjustment 2°C strategy has run out of time, if for no other reason than the "budget" for burning more fossil fuels is now zero, yet the global economy is still deeply committed to their continuing widespread use.

We all wish the incremental-adjustment 2°C strategy had worked, but it hasn't. It has now expired as a practical plan.

We now have a choice to make: accept much higher levels of warming of 3–5°C that will destroy most species, most people and most of the world's ecosystems; a set of impacts some more forthright scientists say are incompatible with the maintenance of human civilisation.

Or we can conceive of a safe-climate emergency-action approach which would aim to reduce global warming back to the range of conditions experienced during the last 10,000 years, the period of human civilisation and fixed settlement. This would involve fast and large emissions reduction through radical energy demand reductions, whilst a vast scaling-up of clean energy production was organised, together with the remaking of many of our essential systems such as transport and food production, with the target being zero net emissions. In addition, there would need to be a major commitment to atmospheric carbon dioxide drawdown measures. This would need to be done at a speed and scale more akin to the "war economy", where social and economic priority is given to what is perceived to be an overwhelming existential threat.

After 30 years of climate policy and action failure, we are in deep trouble and now have to throw everything we can muster at the climate challenge. This will be demanding and disruptive, because there are no longer any non-radical, incremental paths available.

Prof. Kevin Anderson and Dr Alice Bows, writing in the journal Nature, say that "any contextual interpretation of the science demonstrates that the threshold of 2°C is no longer viable, at least within orthodox political and economic constraints" and that "catastrophic and ongoing failure of market economics and the laissez-faire rhetoric accompanying it (unfettered choice, deregulation and so on) could provide an opportunity to think differently about climate change" (17).

Anderson says there is no longer a non-radical option, and for developed economies to play an equitable role in holding warming to 2°C (with 66% probability), emissions compared to 1990 levels would require at least a 40% reduction by 2018, 70% reduction by 2024, and 90% by 2030. This would require "in effect a Marshall plan for energy supply". As well low-carbon supply technologies cannot deliver the necessary rate of emission reductions and they need to be complemented with rapid, deep and early reductions in energy consumption, what he calls a radical emission reduction strategy (18). All this suggests that even holding warming to a too-high 2°C limit now requires an emergency approach.

Emergency action has proven fair and necessary for great social and economic challenges we have faced before. Call it the great disruption, the war economy, emergency mode, or what you like; the story is still the same, and it is now the only remaining viable path.

The Art of Climate Change

by Dorsi Lynn Diaz

Help be a part of the solution! The Art of Climate Change on Kickstarter - an interactive social media & art show/exhibit this summer.

Climate change is HERE and climate change is happening NOW. It is not a figment of your imagination and the weather outside indeed is "frightening."

As I write this, the UK is getting battered by unprecedented storms and in California where I live, we are facing the possibility of a MEGA drought. As a long-time artist, writer and educator, I have been sounding the alarm bell for years. The question loomed large for me: How are we, as a collective society, going to tackle a huge problem?

That was when I had a light-bulb moment.

The idea came to me last year when I realized we need to have a multi-modal approach to addressing climate change. A hands-on, interactive dialogue with great visuals. In order to tackle the problem we needed to look at all the different aspects of climate change. And thus, the "The Art of Climate Change" was born - and the idea for a project: an art show and exhibit. But not your typical art show!

This show would be interactive and get people thinking about SOLUTIONS to climate change, challenge them to think out of the box, and most importantly, educate them about the how and wheres of climate change plus why places like the Arctic matter. This show could travel to cities and communities all over, and be a blue-print for teaching people about climate change and engage their own local artists, inventors and community in learning about "the problem."



But first I needed a venue to do the first show, and that would be one of the biggest hurdles. I connected with a local gallery, pitched the idea to them and they were impressed. In fact, they really liked my idea because it was "different" because it talked about solutions, not just doom and gloom. So now that I've been approved by their Board of Directors, I've got my venue and the show has taken on a life it its own.

The Art of Climate Change has its venue! Whoooppee!! The show is on the datebook - and it will be in run from June 19 - July 27, 2014 at The Sun Gallery in Hayward, Ca. (located in the Silicon Valley area)

I need help and support however to pull this off. This is a huge endeavor and the show has many different facets to it. I have many costs involved: Marketing, advertising, sign production, printing for the science graphics, some travel, equipment rentals (laptops and TV screens), art supplies, website hosting and building and other production costs... and this is why I am asking for your help. Not only will there be "art" on the walls but there will also be a series of artwork by children on endangered species that I have been teaching for the last several months.

The sections of the exhibit have been broken down into the following areas:

1. A section where we talk about "The Problem". This is where we talk turkey and explain the problem and take a good look at it.

2. There will be a section of the exhibit dedicated to extreme weather photos and art. Like they say, a picture can tell a thousand words, right?

3. Next we need to talk about "The Arctic and why it matters". Those record cold snaps happening in the US? Those are one of the strongest symptoms of our melting Arctic. That's due to our now meandering jet stream.

4. The Methane Monster. Yes there are monsters and this is probably one of the biggest ones we need to be worried about. Remember the dinosaur extinction? Well, scientists say that methane was their undoing. And we certainly don't want to go the way of the dinosaurs, right? So yes, we need to talk about the elephant in the room - that pesky methane monster. Which, by the way, is being released in some pretty scary amounts right now from underneath that warming Arctic water. No, it's not good. Not good at all.

5. A section just for THE CHILDREN and EDUCATION. This is the biggest reason I am doing this project. I want to be part of the solution to securing their future. One of the big parts of this project is teaching the kids. Right now I am doing a series of projects with them on endangered animal species. The way I look at it is if we can "teach the children we can touch the world." Their artwork will be prominently displayed in the art/show exhibit. So far they have done done art of endangered Polar Bear cubs, the Monarch Butterfly, Bees, Barn Owls and the Maui Dolphin.

6. A section with a "CALL TO ACTION"....this is where attendees are encouraged to engage with the problem so they can BE PART of the solution...which btw is the next big part of the art show/exhibit....

7. SOLUTIONS. This is where I have things planned that are definitely out of the box. Like inventions to slow down climate change by friends of mine that happen to be very creative too.

So that is my Kickstarter project in a very big nutshell. The really exciting thing though is how this blooming project has just sort of "vacuumed people" up...all kinds of people...from all around the world! Here are some of them that are going to be part of my project:
  • Climate Change Professor Paul Beckwith from the University of Ottawa, who will do a live Skype Q & A session with us. Attendees can sit down face to face with a leading climate change educator and ask questions about climate change from inside the show.
  • A life size mural of a Polar Bear with an Arctic scene, painted in the show/exhibit hall by muralist Lisa Hamblett-Montagnese.
  • Photographer Rose Gold will make the day even more special for kids by taking photos of them with the Polar bear.
  • A display of children and families climate change (endangered species) artwork from students of the Sun Gallery, A Joyful Noise Learning Center, Green Forest Art Studio, The Community Church of Hayward and Young Rembrandt's of the East Bay
  • A live viewing of Andy Lee Robinsons video on a flat screen TV which will be available for viewing all during the exhibits 5 1/2 weeks. Andy's video shows the decline of the Arctic ice accompanied by a musical composition by Andy called "Ice Dreams"
  • A graphic of "The Arctic Death Spiral" by Andy Lee Robinson, to be displayed in the Arctic section of the show.
  • A full size poster by Sam Carana (who set up the Arctic Methane Emergency Group on FB and edits the Arctic-News blog) on the effects of runaway climate change, designed by Sam and displayed in the Arctic section.
  • Original cartoons by Sam Carana, also an adviser on this project, displayed in the Methane section of the show.
  • Quotes with ideas by Harold Hensel, contributor to the Arctic-news blog and advisor on this project.
  • A full size poster of a tunnel invention as a possible solution to our warming waters by Patrick McNulty. Posted in Solutions.
  • A display of alternative fuel named "Bio-Fuel" with information by inventor Jay Toups. Posted in Solutions.
  • A live aquaponics display by Michael and Natalie Elola of Lucky Garden Hydroponics on how to grow vegetables and fruit indoors without using soil. Posted in Solutions.
  • A full size Polar bear costume mascot to be used for outreach. Designed and sewn by Nancy Martinez
  • A call for art by The Sun Gallery for extreme weather photos, climate change art and recycled and re-purposed art
  • A display of childrens books about climate change. Joe Santiago's books will also be featured. Displayed under Education.
  • The original video for the project will be displayed on a flat-screen video at the show for 5 1/2 weeks. Video editing and production by Mead Rose at Web Design by Mead.
  • Artistically designed Climate change confections by pastry chef Cori Diaz for the Artists reception
  • A local rock/punk band that sings songs about climate change. They will sing at the Artists reception.
  • Educational tables set up by the City of Hayward with information about the cities climate change plan along with other entities like the EPA, Water Conservation Board, EBMUD and Waste Management.
  • Deagon B. Williams, friend and adviser on this project.
  • Advertising help with the project by Trish McDermott of Avatar Tech Pubs.

Risks and challenges

I have been working on this project already for over 4 months, successfully pulling people together to either create art for the exhibit, or to contribute educational material. The biggest obstacle for the show was of course the venue but I have the venue for the art show/exhibit set in stone from June 19 - July 27 of this year. A solid foundation has been made, the main thing I need help with now is the financial expenses that the show will cost me - like the rental of equipment to do the live Skyping session with Professor Paul Beckwith, and the special art projects I plan to do within our community. I also have plans to do more community outreach to reach more local public agencies and I plan to have more events centered around the show (how much I can do will be determined by how much funding I get)

How will I deal with any special surprises or costs that I might not have possibly factored in? I will do what I always did in business, I will work with the issue and either adjust or downsize that particular part, - possibly even bartering for services, or ask for donations to help with a particular cost.

What unique challenges might I have after the project is funded? Well I don't foresee any emergencies but if there are any, I have a network of people that will help and advise me through any major problems. The only thing I see is that I may not be able to accommodate all the art that may come in, but that's a good problem to have! Better to have more than not enough - and director Liesa Lietzke and Jacqueline Cooper at The Sun Gallery where the show is will be able to help walk me through any major hiccups if there are any.

More extreme weather can be expected



The heaviest rains and floods in 120 years have hit Serbia and Bosnia this week, Reuters and Deutsche Welle report.

The animation below shows the Jet Stream's impact on the weather. Cold temperatures have descended from the Arctic to Serbia and Bosnia in Europe and all the way down to the Gulf of Mexico in North America, while Alaska, California, and America's East Coast are hit by warm temperatures. In California, 'unprecedented' wildfires and fierce winds lead to 'firenadoes', reports CNN.
