Climate Change Accelerating

Methane levels as high as 2562 ppb were recorded on October 9, 2014, as illustrated by the image below.

Many grey areas show up in the image where QC (quality control) failed, as it was too hard to read methane levels in the respective area, apparently due to high moisture levels (i.e. snow, rain or water vapor) in the atmosphere.

As above image illustrates, cloud cover is high over the Arctic, while there is also precipatation in the form of snowfall.

In other words, high levels of methane (above 1950 ppb, colored yellow) could be present over a much larger part of the Arctic Ocean, while methane in these grey areas could be even higher than the measured peak level of 2456 ppb.

This appears to be confirmed by persistent high methane levels over vast areas across the Arctic Ocean both in the morning (top part of the image further above) and in the afternoon (bottom part of image) on 9 October 2014.

Methane levels are this high over the Arctic Ocean for the number of reasons, including:

• The Gulf Stream keeps pushing warm water into the Arctic Ocean.
• The resulting eruptions of methane from the seafloor of the Arctic Ocean constitute a feedback that accelerates warming in the Arctic. 
• As the Arctic warms up more rapidly than the rest of Earth, the Arctic's ice and snow cover will decline, further accelerating warming in the Arctic.
• As the Arctic warms up more rapidly than the rest of Earth, the speed at which jet streams circumnavigates the Northern Hemisphere will weaken, making it meander more, resulting in a greater frequency and intensity of extreme weather events, such as heat waves, droughts and wildfires. 

Here's an example of intense warming. Look at what is currently happening on Greenland.

As the image above right shows, sea surface temperature anomalies as high as +1.89°C hit the North Atlantic (on October 8, 2014). 

Furthermore, high cloud cover over the Arctic (image further above) makes it hard for the heat there to radiate out into space, further contributing to high temperature anomalies.

The image on the right shows high temperature anomalies over Greenland and parts of the Arctic Ocean on October 11, 2014. Note that anomalies are averaged out over the course of the day (and night).

The image below (right) shows anomalies at the top end of the scale hitting large parts of Greenland at a specific time during this day. The left part of the image below shows how this could happen, i.e. jet streams curling around Greenland trapping warm air inflow from the North Atlantic.

As said, as the Arctic warms up more rapidly than the rest of Earth, the speed at which jet streams circumnavigate the Northern Hemisphere will weaken, making the jets meander more and creating patterns that can trap heat (or cold) for a number of days over a given area. Due to the height of its mountains, Greenland is particularly prone to be increasingly hit by heatwaves resulting from such blocking patterns. Warming changes the texture of snow and ice, making it more slushy and darker, which also makes that it absorbs more of the sunlight's heat, further accelerating melting.

As Paul Beckwith warns in an earlier post, melt rates on Greenland have doubled in the last 4 to 5 years, and melt rates on the Antarctica Peninsula have increased even faster. Based on the last several decades, melt rates have had a doubling period of around 7 years or so. If this trend continues, we can expect a sea level rise approaching 7 meters by 2070.

From: More than 2.5 m sea level rise by 2040

These are all indications that the pace of climate change is accelerating in many ways, the most dangerous one being ever larger methane eruptions from the Arctic Ocean's seafloor. As the image below shows, sea surface temperature anomalies are very high in the Arctic Ocean, indicating very high temperatures under the surface.

U.S. Secretary of State John Kerry recently said: “There are now – right now – serious food shortages taking place in places like Central America because regions are battling the worst droughts in decades, not 100-year events in terms of floods, in terms of fires, in terms of droughts – 500-year events, something unheard of in our measurement of weather.” Warning about looming catastrophe, Kerry adds: “Life as you know it on Earth ends. Seven degrees increase Fahrenheit (3.9°C), and we can't sustain crops, water, life under those circumstances.”

The situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog.

How many deaths could result from failure to act on climate change?

A recent OECD study concludes that outdoor air pollution is killing more than 3.5 million people a year globally. The OECD estimates that people in its 34 Member countries would be willing to pay USD 1.7 trillion to avoid deaths caused by air pollution. Road transport is likely responsible for about half.

A 2012 report by DARA calculated that 5 million people were dying each year from climate change and carbon economies, mostly from indoor smoke and (outdoor) air pollution.

Back in 2012, a Reuters report calculated that this could add up to a total number of 100 million deaths over the coming two decades. This suggests, however, that failure to act on climate change will not cause even more deaths due to other causes.

Indeed, failure to act on climate change could result in many more deaths due to other causes, in particular food shortages. As temperatures rise, ever more extreme weather events can be expected, such as flooding, heatwaves, wildfires, droughts, and subsequent crop loss, famine, disease, heat-stroke, etc.

So, while currently most deaths are caused by indoor smoke and outdoor air pollution, in case of a failure to act on climate change the number of deaths can be expected to rise most rapidly among people hit by famine, fresh water shortages, as well as wars over food, water, etc.

How high could figures rise? Below is an update of an image from the earlier post Arctic Methane Impact with a scale in both Celsius and Fahrenheit added on the right, illustrating the danger that temperature will rise to intolerable levels if little or no action is taken on climate change. The inset shows projected global number of annual climate-related deaths for these two scenarios, i.e. no action and little action, and also shows a third scenario of comprehensive and effective action that would instead bring temperature rise under control.

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.

Near-Term Human Extinction

Global Warming and Feedbacks

Is there a mechanism that could make humanity go extinct in the not-too-distant future, i.e. within a handful of decades?

Most people will be aware that emissions due to human activity are causing global warming, as illustrated by the arrow marked 1 in the image on the left. Global warming can cause changes to the land, to vegetation and to the weather. This can result in wildfires that can in turn cause emissions, thus closing the loop and forming a self-reinforcing cycle that progressively makes things worse.

Furthermore, less forests and soil carbon also constitute a decrease in carbon sinks, resulting in carbon that would otherwise have been absorbed by such sinks to instead remain in the atmosphere, thus causing more global warming, as illustrated by the additional downward arrow in the image on the right. In conclusion, there are a number of processes at work that can all reinforce the impact of global warming.

Emissions can also contribute more directly to land degradation, to changes in vegetation and to more extreme weather, as indicated by the additional arrow pointing upward in the image on the right. A recent study by Yuan Wang et al. found that aerosols formed by human activities from fast-growing Asian economies can cause more extreme weather, making storms along the Pacific storm track deeper, stronger, and more intense, while increasing precipitation and poleward heat transport.

Accelerated Warming in the Arctic

Similar developments appear to be taking place over the North Atlantic. Huge pollution clouds from North America are moving over the North Atlantic as the Earth spins. In addition, the Gulf Stream carries ever warmer water into the Arctic Ocean. As the image below shows, sea surface temperature anomalies at the highest end of the scale (8 degrees Celsius) are visible off the coast of North America, streching out all the way into the Arctic Ocean.

As said, feedbacks as are making the situation progressively worse. Feedback loops are causing warming in the Arctic to accelerate. Warming in the Arctic is accelerating with the demise of the snow and ice cover in the Arctic, and this is only feedback #1 out out many feedbacks that are hitting the Arctic, as described in an earlier post. As the temperature difference between the equator and the Arctic decreases, the Jet Stream is changing, making it easier for cold air to move out of the Arctic and for warm air from lower latitudes to move in (feedback #10).

Abrupt Climate Change leading to Extinction at Massive Scale

The danger is that, as temperatures over the Arctic Ocean warm up further and as the Gulf Stream carries ever warmer water into the Arctic Ocean, large quantitities of methane will erupt abruptly from the seafloor of the Arctic Ocean, adding a third kind of warming, runaway warming resulting in abrupt climate change, and leading to mass death, destruction and extiction of species including humans.

Persistence of such a progression makes it inevitable that the rest of Earth will follow the huge temperature rises in the Arctic. Massive wildfires will first ignite across higher latitudes, adding further greenhouse gas emissions and causing large deposits of soot on the remaining snow and ice on Earth, with a huge veil of methane eventually spreading around the globe. The poster below, from an earlier post, illustrates the danger.

Views by Contributors

How likely is it that the above mechanism will cause human extinction within the next few decades? What views do the various contributors to the Arctic-news blog have on this?

Guy McPherson has long argued that, given the strengths of the combined feedbacks and given the lack of political will to take action, near-term human extinction is virtually inevitable.

In the video below, Paul Beckwith responds to the question: Can climate change cause human extinction?

Further contributors are invited to have their views added to this post as well. While many contributors may largely share Paul Beckwith's comments, it's important to highlight that contributors each have their own views, and this extends to their preference for a specific plan of action.

Geo-engineering

One of the more controversial issues is the use of geo-engineering. Guy McPherson doesn't believe geo-engineering will be successful. In the video below, Paul Beckwith gives his (more positive) views on this.

I must admit that the lack of political will to act is rather depressing, especially given the huge challenges ahead. So, I can understand that this can make some of us pessimistic at times. Nonetheless, I am an optimist at heart and I am convinced that we can get it right by giving more support to a Climate Plan that is both comprehensive and effective, as discussed at ClimatePlan.blogspot.com

Locating sources of the world's highest methane levels

Above image shows IASI methane readings end October 2013 on the Northern Hemisphere. Clearly, high methane levels are very prominent over the Arctic. Over this period, the following peak methane readings have been recorded:
- October 28 - 2369 ppb
- October 29 - 2303 ppb
- October 30 - 2480 ppb
- October 31 - 2332 ppb

[ click on image to enlarge ]

Above image shows methane readings of 1950 ppb and higher in yellow, but only on October 31, 2013, pm.

This image is easier to analyze, since there are only a few areas where high methane readings show up, such as:

• The Gobi Desert, on the border of China and Mongolia. This is an area of concern, as discussed in the post Is Global Warming breaking up the Integrity of the Permafrost?

• Areas along the bounderies of the Okhotsk Plate; seismic activity appears to be contributing to methane releases here, as earlier discussed in the post Earthquake hits waters off Japan. Zoom in at methanetracker.org for details on earthquakes. 

• Last but not least, there's a huge area with high methane readings over the Arctic Ocean.

The image below again shows methane readings of 1950 ppb and higher in yellow on October 31, 2013, pm, but this time only for 3 altitudes, i.e. 451 mb, 469 mb and 487 mb. These levels were selected for their proximity to the altitude of 469 mb, where typically the highest mean global methane levels are recorded, i.e. from 1809 ppb to 1812 ppb for the period from October 28 to 31, 2013. Not surprisingly, the image below looks much the same as above image.

Things look rather different, though, when 3 altitudes are selected closer to sea level. The image below again shows methane readings of 1950 ppb and higher in yellow on October 31, 2013, pm, but this time only at 718 mb, 742 mb and 766 mb. These altitudes showed the highest methane readings that day, of 2322 ppb, 2332 ppb and 2316 ppb, respectively.

Ominously, high methane readings at these lower altitudes show up mostly in the Laptev Sea. In conclusion, some of the world's highest methane levels show up over the Laptev Sea, a huge area most prone to abrupt release of huge amounts of methane from the seabed.

This is further evidence in support of the looming threat of Abrupt Climate Change leading to extinction of many if not all species (i.e. including humans) within decades. It disproves the efforts of the IPCC, as discussed in the post Just do NOT tell them the monster exists, and further organizations to downplay the threat by spreading myths.

How Do We Act in the Face of Climate Chaos?

Guy McPherson

Guy R. McPherson is Professor Emeritus of Natural Resources
and Ecology & Evolutionary Biology at University of Arizona.
Below are some (slighly edited) extracts from a post at Guy
McPherson's website: summary and update on climate change.

The Warning

As described by the United Nations Advisory Group on Greenhouse Gases in 1990, temperature rise “beyond 1 degree C may elicit rapid, unpredictable and non-linear responses that could lead to extensive ecosystem damage”.

We’ve clearly triggered the types of positive feedbacks the United Nations warned about in 1990. Yet my colleagues and acquaintances think we can and will work our way out of this horrific mess with permaculture (which is not to denigrate permaculture, the principles of which are implemented at the mud hut). Reforestation doesn’t come close to overcoming combustion of fossil fuels, as pointed out in the 30 May 2013 issue of Nature Climate Change. Furthermore, forested ecosystems do not sequester additional carbon dioxide as it increases in the atmosphere, as disappointingly explained in the 6 August 2013 issue of New Phytologist.

Here’s the bottom line: On a planet 4 C hotter than baseline, all we can prepare for is human extinction (from Oliver Tickell’s 2008 synthesis in the Guardian).

John Davies concludes: “The world is probably at the start of a runaway Greenhouse Event which will end most human life on Earth before 2040.” He considers only atmospheric carbon dioxide concentration, not the many self-reinforcing feedback loops described below. 

Positive feedbacks

Positive feedbacks

Methane hydrates are bubbling out the Arctic Ocean (Science, March 2010). According to NASA’s CARVE project, these plumes were up to 150 kilometers across as of mid-July 2013. Whereas Malcolm Light’s 9 February 2012 forecast of extinction of all life on Earth by the middle of this century appears premature because his conclusion of exponential methane release during summer 2011 was based on data subsequently revised and smoothed by U.S. government agencies, subsequent information — most notably from NASA’s CARVE project — indicates the grave potential for catastrophic release of methane. Catastrophically rapid release of methane in the Arctic is further supported by Nafeez Ahmed’s thorough analysis in the 5 August 2013 issue of the Guardian as well as Natalia Shakhova’s 29 July 2013 interview with Nick Breeze (note the look of abject despair at the eight-minute mark).

Warm Atlantic water is defrosting the Arctic as it shoots through the Fram Strait (Science, January 2011).

Siberian methane vents have increased in size from less than a meter across in the summer of 2010 to about a kilometer across in 2011 (Tellus, February 2011)

Drought in the Amazon triggered the release of more carbon than the United States in 2010 (Science, February 2011). In addition, ongoing deforestation in the region is driving declines in precipitation at a rate much faster than long thought, as reported in the 19 July 2013 issue of Geophysical Research Letters.

Peat in the world’s boreal forests is decomposing at an astonishing rate (Nature Communications, November 2011)

Invasion of tall shrubs warms the soil, hence destabilizes the permafrost (Environmental Research Letters, March 2012)

Greenland ice is darkening (The Cryosphere, June 2012)

Methane is being released from the Antarctic, too (Nature, August 2012). According to a paper in the 24 July 2013 issue of Scientific Reports, melt rate in the Antarctic has caught up to the Arctic.

Russian forest and bog fires are growing (NASA, August 2012), a phenomenon consequently apparent throughout the northern hemisphere (Nature Communications, July 2013). The New York Times reports hotter, drier conditions leading to huge fires in western North America as the “new normal” in their 1 July 2013 issue. A paper in the 22 July 2013 issue of the Proceedings of the National Academy of Sciences indicates boreal forests are burning at a rate exceeding that of the last 10,000 years.

Cracking of glaciers accelerates in the presence of increased carbon dioxide(Journal of Physics D: Applied Physics, October 2012)

The Beaufort Gyre apparently has reversed course (U.S. National Snow and Ice Data Center, October 2012)

Exposure to sunlight increases bacterial conversion of exposed soil carbon, thus accelerating thawing of the permafrost (Proceedings of the National Academy of Sciences, February 2013)

The microbes have joined the party, too, according to a paper in the 23 February 2013 issue of New Scientist

Summer ice melt in Antarctica is at its highest level in a thousand years: Summer ice in the Antarctic is melting 10 times quicker than it was 600 years ago, with the most rapid melt occurring in the last 50 years (Nature Geoscience, April 2013). Although scientists have long expressed concern about the instability of the West Atlantic Ice Sheet (WAIS), a research paper published in the 28 August 2013 of Nature indicates the East Atlantic Ice Sheet (EAIS) has undergone rapid changes in the past five decades. The latter is the world’s largest ice sheet and was previously thought to be at little risk from climate change. But it has undergone rapid changes in the past five decades, signaling a potential threat to global sea levels. The EAIS holds enough water to raise sea levels more than 50 meters.

Floods in Canada are sending pulses of silty water out through the Mackenzie Delta and into the Beaufort Sea, thus painting brown a wide section of the Arctic Ocean near the Mackenzie Delta brown (NASA, June 2013)

Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a study accepted for publication in the Journal of Geophysical Research: Earth Surface (July 2013). It appears a Heinrich Event has been triggered in Greenland. Consider the description of such an event as provided by Robert Scribbler on 8 August 2013:

In a Heinrich Event, the melt forces eventually reach a tipping point. The warmer water has greatly softened the ice sheet. Floods of water flow out beneath the ice. Ice ponds grow into great lakes that may spill out both over top of the ice and underneath it. Large ice damns (sic) may or may not start to form. All through this time ice motion and melt is accelerating. Finally, a major tipping point is reached and in a single large event or ongoing series of such events, a massive surge of water and ice flush outward as the ice sheet enters an entirely chaotic state. Tsunamis of melt water rush out bearing their vast floatillas (sic) of ice burgs (sic), greatly contributing to sea level rise. And that’s when the weather really starts to get nasty. In the case of Greenland, the firing line for such events is the entire North Atlantic and, ultimately the Northern Hemisphere.

Breakdown of the thermohaline conveyor belt is happening in the Antarctic as well as the Arctic, thus leading to melting of Antarctic permafrost (Scientific Reports, July 2013)

Loss of Arctic sea ice is reducing the temperature gradient between the poles and the equator, thus causing the jet stream to slow and meander. One result is the creation of weather blocks such as the recent very high temperatures in Alaska. As aresult, boreal peat dries and catches fire like a coal seam. The resulting soot enters the atmosphere to fall again, coating the ice surface elsewhere, thus reducing albedo and hastening the melting of ice. Each of these individual phenomena has been reported, albeit rarely, but to my knowledge the dots have not been connected beyond this space. The inability or unwillingness of the media to connect two dots is not surprising, and has been routinely reported (recently including here with respect to climate change and wildfires) (July 2013)

Arctic ice is growing darker, hence less reflective (Nature Climate Change, August 2013)

Extreme weather events drive climate change, as reported in the 15 August 2013 issue of Nature (Nature, August 2013)

Ocean acidification leads to release of less dimethyl sulphide (DMS) by plankton. DMS shields Earth from radiation. (Nature Climate Change, online 25 August 2013)

Sea-level rise causes slope collapse, tsunamis, and release of methane, as reported in the September 2013 issue of Geology

Rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorus, hence reducing plankton (Nature Climate Change, September 2013)

Earthquakes trigger methane release, and consequent warming of the planet triggers earthquakes, as reported by Sam Carana at Arctic-news (October 2013)

Arctic drilling was fast-tracked by the Obama administration during the summer of 2012

Supertankers are taking advantage of the slushy Arctic, demonstrating that every catastrophe represents a business opportunity, as pointed out by Professor of journalism Michael I. Niman and picked up by Truthout (ArtVoice, September 2013)

As nearly as I can distinguish, only the latter feedback process is reversible at a temporal scale relevant to our species. Once you pull the tab on the can of beer, there’s no keeping the carbon dioxide from bubbling up and out. These feedbacks are not additive, they are multiplicative. Now that we’ve entered the era of expensive oil, I can’t imagine we’ll voluntarily terminate the process of drilling for oil and gas in the Arctic (or anywhere else). Nor will we willingly forgo a few dollars by failing to take advantage of the long-sought Northwest Passage.

Robin Westenra provides an assessment of these positive feedbacks at Seemorerocks on 14 July 2013. It’s worth a look.

Where we’re going

An increasing number of scientists agree that warming of 4 to 6 C causes a dead planet. And, they go on to say, we’ll be there by 2060. 

Earth-system scientist Clive Hamilton concludes in his April 2013 book Earthmasters that “without [atmospheric sulphates associated with industrial activity] … Earth would be an extra 1.1 C warmer.” In other words, collapse takes us directly to 2 C within a matter of weeks. 

Several other academic scientists have concluded, in the refereed journal literature no less, that the 2 C mark is essentially impossible (for example, see the review paper by Mark New and colleagues published in the 29 November 2010 issue of the Philosophical Transactions of the Royal Society A). 

The German Institute for International and Security Affairs concluded 2 June 2013 that a 2 C rise in global-average temperature is no longer feasible (and Spiegel agrees, finally, in their 7 June 2013 issue), while the ultra-conservative International Energy Agency concludes that, “coal will nearly overtake oil as the dominant energy source by 2017 … without a major shift away from coal, average global temperatures could rise by 6 degrees Celsius by 2050, leading to devastating climate change.”

At the 11:20 mark of this video, climate scientist Paul Beckwith indicates Earth could warm by 6 C within a decade. 

If you think his view is extreme, consider: 

1. the 5 C rise in global-average temperature 55 million years ago during a span of 13 years (reported in the 1 October 2013 issue of Proceedings of the National Academy of Sciences); and also 
2. the reconstruction of regional and global temperature for the past 11,300 years published in Science in March 2013. One result is shown in the above figure.

How Do We Act in the Face of Climate Chaos?

Below is a video of a recent presentation by Guy McPherson. 

Presentation by Guy McPherson in Boulder, Colorado on October 16, 2013.

Below are some extracts from the video, again slightly edited.

Malcolm Light in 2012 concluded, based on data from NOAA and NASA, that methane release had gone exponential and was leading to the demise of all life on Earth, not just human extinction, by the middle of the century.

So 3.5 C to 4 C is almost certainly a death sentence for all human beings on the planet, not because it'll be a warmer planet, but because the warming of the planet will remove all habitat for human beings. Ultimately we're human animals like other animals, we need habitat to survive.

Changes we see in three or four decades happen as a result of what we do today. There's a huge lag between our actions today in the consequences down the road in terms of the Earth's planetary systems.

Without plankton in the ocean, there goes roughly half the global food supply. The ability to lose land plants is growing rapidly and there goes the other half for the food supply for human beings. If we have up to 5 C by 2050, that'll certainly do the trick.

Why is this happening? It's civilization that drove us into population overshoot. We cannot go back anymore since 1939, since we invented nuclear armageddon. There's no going back. If we ceased the set of living arrangements at this point, the world's 400 or so nuclear power plants melt down catastrophically and we're all dead in a month. We cannot terminate industrial civilization until we decommission all nuclear power plants. It takes at least 20 years to decommission a nuclear power plant.

The bad news is that means that the world's four hundred or so nuclear power plants meltdown catastrophically in a short period of time. Fukushima represent a major threat to humanity. If they fail in moving the spent fuel rods next month, according to nuclear researcher Christina Consola, if one of those MOX fuel rods is exposed to the air, one of the 1565, it will kill 2.89 billion people on the planet in a matter of weeks, so nuclear catastrophe is right there on the horizon. 

People ask me: Why are you presenting this horrible information?

Action is the antidote to despair even if the action is hopeless. When a medical doctor knows that somebody has cancer, it's malpractice if they don't tell that. So I'm doing that. I think Bill McKibben and James Hansen and a whole bunch of climate scientists are guilty of malpractice. Because they know what I know. Almost every politician in the country knows what I know. All the leaders of the big banks know what I know. And they're lying to us.

I'm just presenting the information from other scientists here. I'm trying to the widest extent possible not to infuse my opinion in the situation. It's John Davies who on September 20, 2013, taking into account only carbon dioxide, says there will be few people left on the planet by 2040. It's Malcolm Light, writing in February 2012, who assesses the methane situation. And so on.

Yes, I agree with them, and that agreement is illustrated by me showing you that information.

I promote resistance against this omnicidal culture, not in the hope that it will save our species, but in the hope that it will save other species. Because as E.O. Wilson, biologist at Harvard, points out, it only takes 10 million years after a great extinction event, before you have a blossoming full rich planet again. That's what we're working toward. We're saving habitat for other species at this point.

Are Alberta’s Tar Sands prepared for a torrential rain event?

by Paul Beckwith

In recent months we have endured incredible tropical-equatorial-like torrential rain events occurring at mid-latitudes across the planet. For example, in North America we experienced intense rainfall in the Banff region of the Rockies from June 19th to 24th and the enormous volume of water moved downhill through the river systems taking out small towns and running into the heart of Calgary where it caused $5.3 billion dollars of infrastructure damage; the largest in Canadian history.

Next, it was Toronto’s turn, with 75 mm of rain falling from 5 to 6pm on July 8 (with up to 150 mm overall in some regions) leading to widespread flooding and $1.45 billion dollars in damages. As bad as these events were, they were dwarfed by the intense rainfalls hitting the state of Colorado from Sept 9th to 15th.

Rainfall amounts that would normally fall over 6 months to a year were experienced in less than a week. Widespread flash floods, landslides, and torrents of water ripped apart roads, fracking equipment and pipelines on (at least) hundreds of fossil fuel sites (mostly ignored by mainstream media) (http://www.desmogblog.com/2013/09/19/media-ignores-damaged-oil-and-gas-tanks-colorado-floods). The level of destruction was simply horrifying, as captured by a man with a plane and a camera. But we have no grounds for complaint, since the widespread flooding in central Europe from May 30th to June 6th caused a much larger $22 billion in damages.

So what is happening? Why are we experiencing so many of these severe weather flooding events that are supposed to only occur every 1000 years or so? Will they keep occurring? What city will be hit next? Can the Alberta tar sands be hit by such an event? What would be the implications?

Abrupt Climate Change In Real-Time

Humans have benefited greatly from a stable climate for the last 11,000 years - roughly 400 generations. Not anymore. We now face an angry climate. One that we have poked in the eye with our fossil fuel stick and awakened. Now we must deal with the consequences. We must set aside our differences and prepare for what we can no longer avoid. And that is massive disruption to our civilizations.

In a nutshell, the logical chain of events occurring is as follows:

1. Greenhouse gases that humans are putting into the atmosphere from burning fossil fuels are trappingextra heat in the earth system (distributed between the oceans (93%), the cryosphere (glaciers, ice sheets, sea ice for 3%), the earth surface (rocks, vegetation, etc. for 3%) and the atmosphere (only an amazingly low 1%). The oceans clearly get the lions share of the energy, and if that 1% heating the atmosphere varies there can be decades of higher or lower warming, as we have seen recently. This water vapor rises and cools condensing into clouds and releasing its stored latent heat which is increasing storm intensity.
   
2. (i)Rapidly declining Arctic sea ice (losing about 12% of volume per decade) and (ii)snow cover (losing about 22% of coverage in June per decade) and (iii)darkening of Greenland all cause more solar absorption on the surface and thus amplified Arctic warming (global temperatures have increased (on average) about 0.17^oC per decade, the Arctic has increased > 1^oC per decade, or about 6x faster)
   
3. Equator-to-Arctic temperature difference is thus decreasing rapidly
   
4. Less heat transfer occurs from equator to pole (via atmosphere, and thus jet streams become streakier and wavier and slower in west-to-east direction, and via ocean currents (like Gulf Stream, which slows and overruns continental shelf on Eastern seaboard of U.S.)
   
5. Storms (guided by jet streams) are slower and sticking and with more water content are dumping huge torrential rain quantities on cities and widespread regions at higher latitudes than is “normal”.
   
6. A relatively rare meteorological event called an “atmospheric river” is now much more common, and injects huge quantities of water over several days to specific regions, such as Banff (with water running downhill to Calgary) and Toronto and Colorado events.

It is well past the time that politicians and governments need to act to address these issues. This breakdown of the global atmospheric circulation pattern is well underway now, with a global average temperature only 0.8^oC above the pre-industrial revolution levels. With extreme weather events this terrible now, it is highly irrational, in fact reckless, to continue to have global meetings and discussions about whether or not 2^oC is safe. Only 0.8^oC is wreaking havoc on global infrastructure today. As climate change proceeds and accelerates and we move further from the stable state that we are familiar with (“old climate”) to a much warmer world (“new climate”) we will experience worsening weather extremes and a huge “whiplashing” of events (throughout our present “transition period”).

For a notion of whiplashing, consider the Mississippi River. There were record river flow rates from high river basin rainfall in 2011, followed by record drought and record low river water levels in December, 2012 making it necessary for the U.S. Army Corp of Engineers to hydraulically break apart rock on the riverbed to keep the countries vital economic transportation link open to barge traffic. Then, 6 months later, the river was back up to record levels. Incredible swings of fortune.

Mitigation at a global level is dysfunctional and inadequate

Adaption has not worked out too well for Calgary, or Toronto, or Colorado, or numerous other places. Let us not be surprised when a similar torrential rain event hits Ottawa, or Vancouver, or even the Alberta tar sand tailing ponds. In Alberta, tailings ponds would be breached and the toxic waters would overflow the Athabasca River and carry the pollutants up into the north to exit into the Arctic Ocean. Such an event would be catastrophic to the environment and economy of Canada.

How can this risk be ignored? Will the latest IPCC (Intergovernmental Panel on Climate Change) report AR5 released on September 27th once again be ignored by society?
