Climate Plan

What we're witnessing is more than a climate crisis, we're facing climate catastrophe and the outlook is grim. We're already in the Sixth Mass Extinction event and we're facing a potential global temperature rise of 18°C or 32.4°F by 2026. Merely declaring a climate emergency is not enough.

[ from earlier post ]

The Climate Plan advocates measures that can be taken in efforts to improve the situation regarding the climate, as well as regarding the health, prospects and wellbeing of people and life in general. These measures can and should be implemented immediately, in line with the current climate crisis.

Seventeen measures for immediate implementation

1. FOSSIL FUEL - Ban the use of coal and natural gas for heating, cooking and generating electricity. Stop supplying natural gas from utilities over pipelines. Ban sales of natural gas bottles. Use rationing of electricity supply from the grid to overcome bottlenecks in supply, until sufficient clean, renewable electricity can fully supply demand over the grid.

2. NUCLEAR POWER - Stop nuclear power plants from continuing to operate and start decommissioning existing plants. Study options for treating and storing waste from such plants.

3. WOOD AND BIOFUEL - Progressively ban the use of wood and other biomass for generating power, for driving vehicles or for other energy-related purposes. Impose fees on sales of biofuel, while using revenues to fund pyrolysis of biowaste and on return of the resulting biochar to the soil locally. Ban sales and installation of new woodburners. Ban sales or supply of firewood, woodchips, briquets, charcoal, etc. Impose annual fees through local rates on real estate that contain existing woodburners, open fireplaces, and traditional ovens and furnaces that use wood, while using revenues to fund rebates on local sales of clean electric alternatives such as heat pumps.

4. ROAD AND RAIL VEHICLES - Progressively electrify all trains and rail traffic, by imposing fees on trains that run on fossil fuel, while using revenues to fund conversion to or purchase of new electric trains. Progressively ban the use of vehicles with internal combustion in cities, first for one day in the week, then for two days a week, etc. Add fees to annual registration of vehicles with internal combustion engines, and use the revenues to fund rebates on registration of electric vehicles. Progressively close petrol stations and ban sales of products such as gas, diesel, petrol and further fossil fuel. Add fees to sales of fossil fuel and use revenues to fund rebates on clean public transport locally. Ensure there is public access to financial records. Set standards to reduce unnecessary vehicle noise, while ensuring sufficient sound is generated to warn people and wildlife.

5. AVIATION - Progressively ban aviation where flights are powered by jet fuel and other fossil fuel and biofuel. Impose fees on sales of such fuel and use revenues to fund rebates on electric airplanes that can take off and land on rooftops. Similarly, add fees to flights entering and leaving airports by airplanes using fossil fuel, while using revenues to fund electric airplanes that can take off and land on rooftops.

6. SHIPPING - Progressively prohibit use of bunker fuel and other fossil fuel in shipping. Impose fees on sales of bunker fuel, with revenues used to fund batteries and hydrogen fuel cells to replace traditional engines in ships. Impose fees on shipping of fossil fuel, with revenues used to clean up waterways and support wildlife conservation.

7. URBAN WASTE - Progressively make that zero % waste leaves each city, neither by road or boat transport nor through the sky, soil or waterways. Make that waste will be processed within each city, preferably pyrolyzed with biochar and nutrients returned to soils. Add sensors to rubbish bins and garbage collection trucks to ensure that no toxic products are disposed off, unless through collection points that ensure proper processing.

8. PLASTIC - Ensure that no plastic (or plastic parts) will be sold without permit and without fees high enough to ensure return of such items to approved collection points for safe disposal and processing. Ban single-use plastic, such as for packaging, containers, bags, etc.

9. DIET - Progressively ban sales of livestock products, unless supplied for medical purposes if no alternatives are available. Add fees to sales of livestock products, with revenues used to fund rebates on soil and water supplements that contain biochar and olivine sand in rural areas. In coastal areas, use revenues to assist enhanced weathering in waterways. Stop using antibiotics and hormones to stimulate growth in animals. Stop using crop to feed animals, unless for sales of petfood to pets held with a permit. Add fees on sales of products that have carbon dioxide, sugar, salt, flavors or coloring added, with revenues used to promote vegan-organic diet.

10. AGRICULTURE - Add fees on sales of nitrogen fertilizers and use revenues to fund rebates on biochar and enhanced weathering in oceans.

11. WILDLIFE CONSERVATION - Ban chemical pesticides. Remove walls and fences that stop wildlife. Provide ways for wildlife to cross roads and highways. Set aside progressively increasing areas where no urban, agricultural, industrial development is allowed. Move existing buildings, agriculture and industries from such areas. Fund progress through annual fees imposed on real estate in areas zones for industrial, urban and agricultural development.

12. CONSTRUCTION - Add fees on sales of Portland cement, with revenues used to fund carbon-negative construction material used locally. Fees must be high enough to progressively phase out use of Portland cement.

13. AGRICULTURE AND FORESTRY - Prohibit dumping of agricultural and other waste in landfalls, prohibit burning of waste in open fires. Prohibit cutting down large trees without permits. Where permits are supplied, add fees to minimize deforestation, while using revenues to support reforestation and afforestation. Ensure that biowaste gets pyrolyzed, with the biochar returned to the soil locally. Add fees on local rates where soil loses carbon content, with revenues used to fund rebates where soil carbon content increases, such as when biochar and olivine sand are added or when new trees are planted.

14. COOLING - Ban sales of new air-conditioners, fridges and freezers that work with gases. Impose annually rising fees on existing items, while using the revenues from the annual fees to fund rebates on solid state products, including heat pumps.

15. INDUSTRY - Progressively ban the use of fossil fuel in industrial processes by replacing them with clean electricity (i.e. generated by wind turbines or solar panels), or with hydrogen made with such clean electricity. Ban the use of solvents, cleaning substances, propellants and other products that result in further addition of greenhouse gases to the atmosphere. Ensure that manufacturers label products indicating the heating impact.

16. UNIVERSITIES - Encourage further study in the effectiveness of measures in all above areas. Compare what happens locally with what in other areas, to ensure the most effective policy tools are used locally to facilitate the necessary transitions. Government grants are to be given to studies that sufficiently care about above points.

17. FURTHER ACTION - Further lines of action will be needed to hold back the temperature rise. Some action requires further research and U.N. supervision. Some other action has low risk and, due to the urgency to keep temperatures down, testing and R&D should commence immediately. This applies in particular to ways to reduce overheating of the Arctic.

Examples of such measures are Marine Cloud Brightening off the east coast of North America, in efforts to cool the waters entering the Arctic Ocean. Proposals that need further study are the use of icebreakers during the northern Fall and Winter, to enable more heat to escape from the Arctic Ocean, thus reducing the risk of ocean heat destabilizing methane hydrates at the seafloor of the Arctic Ocean. That risk is high from late September when the sea ice starts closing off the Arctic Ocean, thus making it difficult for ocean heat to escape, while warm water is still being carried into the Arctic Ocean from the Atlantic Ocean. Denis Bonnelle has proposed to use icebreakers that travel in parallel and are interconnected to also clear the ice in between them.

While implementation of some of these lines of action requires U.N. supervision, much of the proposed action can readily be implemented locally without delay and the Climate Plan prefers speedy local implementation, with communities deciding what works best locally, provided that a community does take sufficient action to achieve the necessary dramatic reductions in each type of pollution, in line with the Paris Agreement to avoid a large temperature rise. Examples of implementation of some of these lines of action are depicted in the image below, showing examples of how progress can be achieved through local feebates.

[ from earlier post ]

The overview below also includes further possible action that could be considered. Importantly, the situation is that dire that even if all possible action as described is taken, this constitutes no guarantee that any humans will survive the coming decades.

The image below depicts how the above-mentioned measures line up in response to the threat.

In conclusion, the technologies and policy instruments are ready for implementation, so let's stop delaying what's needed so desperately, now is the time for comprehensive and effective action!

Action must be taken now

Some of the world's most preeminent climate scientists, all experts with many decades of experience in their respective field, are warning that effective action must be taken now to avoid catastrophe.

These scientists, and many others, have made valuable and much-appreciated contributions to the Arctic-news blog over the years [note: contributors each express their own views in posts and may or may not endorse other content of this blog].

Sam Carana, editor of this blog, has for years supported the calls of these scientists, also discussing and sharing their calls at facebook groups such as Arctic-News, Electric Transport, Renewables and Climate Alert.

Furthermore, Sam Carana has called for specific action for years, including support for biochar, preferably through feebates. More specifically, Sam Carana recommends that revenues raised from fees imposed on sales of livestock products, nitrogen fertilizers and Portland cement are used to fund support for soil supplements, as illustrated by above image. For more on biochar, see this blog and this facebook group.

For years, Sam Carana has also called for more R&D in specific areas of geo-engineering. For more on this, see this blog and this facebook group.

More generally, Sam Carana advocates the Climate Plan, which calls for a global commitment to parallel lines of action while seeking to delegate implementation to local communities, preferably through effective policies such as local feebates.

This blog has had some success in spreading this message. To date, Sam Carana has received 82,327,368 views at Google plus (see screenshot on the right), while this blog has received 3,255,445 views (see update of views in the panel further on the right).

Regarding the urgency to act, the images below give an update on the terrifying situation in the Arctic, where the sea ice is disappearing fast.

The decline of the snow and ice cover in the Arctic goes hand in hand with rising sea surface temperatures that contribute to sea ice getting ever thinner.

The image on the right show Arctic sea ice on September 1, 2016, with thickness in meters.

The warming of the oceans is illustrated by the images below.

The image directly below shows sea surface temperature (left) and anomalies compared to 1981-2011 (right).

The image below also shows sea surface temperature anomalies, this time compared to 1971-2000.

Global warming has hit the Arctic particularly hard over the past 365 days, with anomalies exceeding the top end of the scale over most of the Arctic Ocean, as illustrated by the image below.

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

Why America should lead on climate

There are many reasons why America should take the lead in action on climate change.

It's fair and in everyone's interest that America takes the lead

It's fair that those who pollute most, do most to clean things up. America's current and historic emissions are huge, while a lot of what has been produced elsewhere is also consumed in America. Moreover, it's in everyone's interest if America takes the lead. That is confirmed by studies such as this one, showing that there are no technical or economic barriers against cleaning things up. Doing so has many benefits, including job and investment opportunities, and scope for exports. In order for American industries, such as car manufacture, to remain competitive with products from overseas, they must clean up their act. In addition, there are many health and the environmental benefits, while shifting to clean energy will remove perceived needs for America to send military forces across the world to protect global supply lines of fossil fuel.

Legal obligations to act

There are also legal obligations for America to act. Back in 2007, the Supreme Court ruled in Mass. v. EPA that the EPA must act on any air pollutant that endangers public health or welfare. The EPA subsequently found this to be the case for six greenhouse gases and took action, including by issuing plans to limit carbon emissions from power plants. More recently, the United States Court of Appeals for the DC Circuit ruled in favor of the EPA plans.

Furthermore, as Michael Burger points out, Section 115 of the Clean Air Act also authorizes the EPA to act on emissions that contribute to air pollution that endangers public health or welfare in other countries, the more so where the other countries provide the U.S. with reciprocal protections. At the Paris Agreement, such reciprocity was affirmed by some 190 nations (accounting for over 93% of current GHG emissions) pledging to hold the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels.

In other words, no new laws are needed and action can and should be taken now, as this blog has pointed out for years, e.g. in this 2014 post that featured the image below.



The threat of methane eruptions from the Arctic Ocean seafloor calls for urgent action

This blog has repeatedly pointed at another reason why especially America must act, and must do so rapidly, comprehensively and effectively. In October 2015, oceans reached record high temperatures, especially on the Northern Hemisphere, as illustrated by the image below.

Northern Hemisphere October ocean temperatures based on NOAA 1880-2015 data - plot area goes from 1900 to 2050 and from -1 to 4 degrees Celsius above baseline, i.e. compared to the period 1901-2000, the 20th century average.

Above image features a trendline showing that oceans on the Northern Hemisphere could, by the year 2043, be 4°C or 7.2°F warmer than the 20th century average. Increasingly, methane levels over the Arctic Ocean are showing strong increases from October onward, as huge amounts of ocean heat are reaching the seafloor of the Arctic Ocean from that month onward.

North America contributes strongly to accelerating warming of the Arctic Ocean. The Coriolis Effect makes that high levels of emissions originating from North America are extending over the Atlantic Ocean, and are warming up waters off the east coast of North America, as illustrated by the image below.

Top left: CO2 414 ppb green circle, up to 433 ppm in New Jersey. Top right: CO 274 ppb green circle, up to 890 ppb in New Jersey. Bottom left: Jet Stream 250 hPa. Bottom right: Sea surface temperature anomaly 8.5°C/15.3°F green circle.

2015 maximum nightly sea surface temperature anomaly

Carbon dioxide emissions are important, but also relevant are other emissions such as carbon monoxide that depletes hydroxyl, making it harder for methane to be oxidized.

As emissions keep rising, the Gulf Stream will carry ever warmer water into the Arctic Ocean, resulting in greater melting of the sea ice and associated albedo changes that in turn accelerate warming in the Arctic.

Surface temperature anomaly Jan 21, 2015 - Jan 20, 2016
 

This is further illustrated by the images on the right. The top image shows 2015 maximum nightly sea surface temperature anomalies, with anomalies of 5°C off the North American east coast as well as in the Arctic Ocean.

The second image on the right illustrate the extent at which warming in the Arctic Ocean is accelerating, compared to the rest of the world. The image also shows the cold freshwater lid over the North Atlantic.

Temperature anomaly forecast for January 28, 2016
 

As the temperature difference between the Arctic and the equator decreases, the jet stream gets more elongated, at times moving all across the Arctic Ocean. This is one of a multitude of feedbacks that contribute to accelerating warming of the Arctic Ocean. The result is illustrated by the third image on the right, showing strong warming over most of the Arctic Ocean, while at the same time some places on land at higher latitudes north are experiencing extremely cold conditions.

descending cold freshwater on January 25, 2016

Another one of such feedbacks is that warmer water off the coast of North America will result in stronger winds moving over the North Atlantic toward the Arctic Ocean. This can also speed up ocean currents, so it can result in more heat being carried toward the Arctic Ocean both in the atmosphere and the water.

Meltwater from glaciers and sea ice can descend along the edges of Greenland into the North Atlantic, forming a cold freshwater lid on the North Atlantic, where it accumulates at the surface over the years, as illustrated by the image on the right that points at a -4°C or -7.1°F anomaly compared to 1981-2011.

In addition, precipitation (rain, snow, hail, fog, etc.) can further contribute to expansion of this cold
freshwater lid over the North Atlantic, as illustrated by the images on the right.

cold freshwater lid over the North Atlantic

While this cold freshwater may constitute a barrier that slows the flow of warm water toward the Arctic Ocean at the surface, the danger is that it prevents heat transfer to the atmosphere from warm water flowing below the sea surface, with the net result of more heat arriving in the Arctic Ocean.

Furthermore, if this cold freshwater lid also prevents water from sinking deeper in the North Atlantic, this may also contribute to more warm water arriving in the Arctic ocean, as illustrated by the bottom image on the right.

Such feedbacks can dramatically accelerate warming of Arctic Ocean, resulting in heat destabilizing sediments that can contain huge amounts of methane.

In conclusion, America must take the lead in action on climate change. It's fair to do so, it will benefit everyone, there are legal obligations to do so and there is great urgency to act in the light of looming methane eruptions from the seafloor of the Arctic Ocean.

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

Save the Arctic sea ice while we still can!

The Arctic Ocean is coming close to complete summer meltdown, writes John Nissen - indeed it could happen as soon as September, triggering a severe deterioration in climate across the northern hemisphere. With fast-rising temperatures predicted in the coming decade, we must act now to save the Arctic, before it's too late.

---

By John Nissen

John Nissen: "Nothing has been said by the
IPCC. Nothing has been said in the
mainstream media. Nothing has been said
by the scientific community at large. This
is a terrible omission. It is quite scandalous."

Fossil fuel companies, and their supporters in government, seem blissfully unaware of the dangers ahead, threatening everybody on this planet.

The sea ice is declining far more rapidly than anyone expected. It is declining towards disappearance in summer months, yet the colossal negative impact of a low albedo Arctic has hardly been discussed. This is tragic because the whole situation could have been avoided with good leadership at negligible economic cost.

And as reported this week on The Ecologist, new scientific research indicates that the apparent 'pause' in global warming has, in fact, been no such thing. Instead the surplus heat - two Hiroshima bombs-worth a second - has simply been 'buried'
deep in the Pacific Ocean.

That's because of two important climate cycles, the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation, whose operation has masked the warming. But soon they will tip the other way and the 'Big Heat' is set to begin - a five to ten year burst of rapid warming that will be most severe in the Arctic.

Commercial advantages for some ...

If you read the mainstream media, only the positive impact of a melting Arctic is mentioned: an Arctic ripe for exploitation.

Through not grasping the huge negative impact of a low albedo Arctic, the fossil fuel companies still appear entirely happy for the sea ice to disappear as quickly as possible - the sooner the better. Therefore they naturally resist any action to save the sea ice. In particular they don't want geoengineering deployed to cool the Arctic, because it might succeed in saving it!

Certain fossil fuel companies have already invested heavily in exploiting the vast store of oil and gas in the Arctic. These companies, and the governments who support them, are preparing for a bonanza when the sea ice disappears in summer: it will be so much easier and safer to extract the fossil fuel when the sea ice and freezing conditions have gone during summer months.

Furthermore, the disappearance of the sea ice will open up the Northwest Passage and the Northern Sea Route (formerly known as the Northeast Passage) to trade through summer months. So China and nations bordering the Atlantic (including the UK) are expecting to benefit enormously. Russia is investing heavily in ports and infrastructure to support the anticipated heavy traffic.

Various environment groups and the UK Environment Audit Committee have argued against drilling in the Arctic because they are concerned about oil spills and gas blow-outs which could ruin the local environment. They also seek to protect the wild life and Arctic ecosystem. But their arguing will be futile once the sea ice has gone in summer. It will be too late to protect the environment.

Environmentists have less concern about the opening up of the trade routes, because this will reduce CO2 emissions from transport of goods which at present have much longer journeys.

The Arctic bombshell is waiting to go off

While there is all this talk of exploiting the Arctic, little or nothing is said about the adverse effects of having an Arctic free of sea ice during summer months.

Nothing has been said by the IPCC. Nothing has been said in the mainstream media. Nothing has been said by the scientific community at large. This is a terrible omission. It is quite scandalous.

While most experts agree that there will come a time when the Arctic Ocean will be free of ice during summer months, there is no such agreement on the time-scale. Models suggest that it will take decades.

But observations of an exponential trend of sea ice decline suggest that this time could be within a decade. Scientific reports of especially rapid temperature rise in Alaska have also emerged. For example Barrow, Alaska, has experienced a 7°C temperature rise over 34 years, attributed to the decline in sea ice.

So what are the effects? During summer months, a vast area of reflective ice will have been replaced by open water, absorbing 90% of sunshine and warming the Arctic air above. It is clear that the Arctic will be warming much faster than at present - likely at over 2°C per decade.

As heat dissipates around the planet, there will be a huge contribution to global warming in the long term. Estimates put this at equivalent of 3.3 W/m2 (Flanner, 2011) or about twice the current warming from CO2.

But what are the immediate consequences of this super-rapid warming in the Arctic? At present we have an acceleration of three particular processes, affected by Arctic warming to date:

• Firstly, we have a dramatic rise in Northern Hemisphere weather extremes, as the jet stream behaviour is disrupted.
• Secondly we have an exponential increase in meltwater from the Greenland Ice Sheet, flowing through moulins on the surface of the ice into the sea and raising the sea level.
• And thirdly we have a dramatic increase in methane emissions from the Arctic Ocean seabed.

As the temperature in the Arctic continues to increase, these processes will continue almost indefinitely. We can expect worsening Northern Hemisphere climate causing widespread crop failures; faster sea level rise causing progressive flooding of low-lying regions; and growing methane emissions leading to even more catastrophic global warming.

These are three immediate results of the switching on of heat as the Arctic Ocean enters the low sea-ice state. The combination will be devastating for all mankind - with mass starvation and mass migration liable to trigger a world war.

This is the terrifying bombshell. The bonanza will be short-lived, as the effects of a seasonally ice free Arctic Ocean begin to bite.

For a few billion dollars a year, we can save the Arctic

Something must be done to prevent the ocean entering this low-ice state. Therefore the Arctic must be cooled enough to save the sea ice.

The first moment at the end of summer that the sea ice finally disappears from the ocean is called the 'blue ocean event'. It is significant because it could mark the entry of the ocean into a permanent low-ice state for subsequent years - the point of no return. The point of no return could be a soon as next September.

By any ordinary standards, we have left it too late to cool the Arctic. But any reduction in the risk of passing the point of no return is worthwhile, when all our futures are at stake.

Fortunately researchers are increasingly confident that a stratospheric aerosol haze, produced from sulphur dioxide, SO2, could provide significant cooling of the Arctic for modest expenditure of the order of a few billion dollars per year.

This type of cooling could be replaced by cloud brightening using ultra-fine seawater droplets when the technology is ready for large-scale deployment within a year or two.

There should be no significant negative economic impact from this action, except that the resources in the Arctic become frozen assets. But they should be frozen assets in any case if global warming is to be kept below 2°C, according to a recent paper.

There should be positive political impact, because governments will be working together in a common cause to protect their own citizens and all the citizens of the world. The fossil fuel industry has to be persuaded that preserving the Arctic sea ice is essential for the future of themselves and their stakeholders.

Objections from the anti-geoengineering lobby have to be overcome, because we have no other realistic option to reduce the colossal risk of passing a point of no return this September.

Ocean Temperature Rise

Ocean Temperatures

Of all excess heat resulting from people's emissions, 93.4% goes into oceans. Accordingly, the temperature of oceans has risen substantially.

Globally, the average September ocean temperature marked a record high for that month in 2014, at 0.66°C (1.19°F) above the 20th century average, breaking the previous record that was set just one month earlier. On the Northern Hemisphere, the temperature of the ocean in September 2014 was 0.83 °C (or 1.49 °F) above the 20th century, 

The anomaly was 0.84 °C in August 2014, as illustrated by the image below.

On specific days, anomalies were much higher. On August 19, 2014, the Northern Hemisphere showed a sea surface temperature anomaly of 1.78 °C, while the North Atlantic sea surface temperature was 1.82 °C above average (CFSR 1979-2000 Baseline) on October 16, 2014, as illustrated by the image below.

Sea surface temperature anomalies are at the top end of the scale in many places in the Arctic, as well as off the coast of North America. The danger is that the Gulf Stream will keep carrying ever warmer water from the North Atlantic into the Arctic Ocean, threatening to unleash huge methane eruptions from the Arctic Ocean's seafloor, in turn causing even higher temperatures and more extreme weather events, wildfires, etc.

Above image shows methane levels as high as 2666 ppb, as measured by the MetOp-2 Satellite at 14,385 ft (~4.4 km) altitude on October 26, 2014 am.

Is 2666 ppb as high as it will get?

Sadly, methane releases from the seafloor of the Arctic Ocean are becoming increasingly larger around this time of year and they look set to get even larger than this. Note that the amount of methane actually erupting from the seafloor of the Arctic Ocean is even larger than what is visible on above image, for the following three reasons.

1. No data were available for some areas, as the IASI (Infrared Atmospheric Sounding Interferometer) instrument measuring methane only covers a certain width. The white shapes showing up on above images are areas where no measurements were taken, resulting from the way the polar-orbiting satellite circum-navigates the globe, as pictured on the image on the right.
   
   Furthermore, quality control failed in the grey areas on above images, indicating reading difficulties due to high moisture levels (i.e. snow, rain or water vapor), as also discussed in an earlier post. Accordingly, high methane levels (above 1950 ppb) as show up in the yellow areas could also be present in the many grey areas over the Arctic Ocean.
   
   When also looking at methane levels on days following the high 2666 ppb reading, methane is persistently present over most of the Arctic Ocean, as illustrated by the above October 29, 2014, combination image, confirming that high methane levels were likely present in areas where no data were available on October 6, 2014.
      
   
2. Much of the methane that is released from the Arctic Ocean's seafloor is broken down by microbes as it rises up in the water. The SWERUS-3 research team recently found methane in the waters of the East Siberian Sea at levels that equate to atmospheric levels of  3188 ppb.
      
   
3. Much methane is broken down in the atmosphere by hydroxyl, as illustrated by the image below, showing carbon dioxde levels on October 27, 2014, that indicate that large amounts of methane are broken down at higher latitudes on the Northern Hemisphere.

The latter point could explain the sudden recent rise in carbon dioxide levels, as also detected at Mauna Loa, Hawaii, as illustrated by the image below.

In conclusion, the amount of methane that is erupting from the seafloor of the Arctic Ocean is larger than what is visible on satellite images, and the water will be highly saturated with methane at locations where the methane is escaping from the seafloor, highlighting the danger that, in case of large abrupt releases from the Arctic Ocean's seafloor, microbes and hydroxyl will quickly get depleted locally, resulting in little of the methane being broken down, as discussed at an earlier post.

Why are such huge amounts of methane starting to get released from the Arctic Ocean's seafloor now?  

As the image below shows, temperature at 2 meters was below 0°C (32°F, i.e. the temperature at which water freezes) over most of the Arctic Ocean on October 26, 2014. The Arctic was over 6°F (3.34°C) warmer than average, and at places was up to 20°C (36°F) warmer than average.

Above image illustrates the enormous amount of heat that has until now been transferred from the waters of the Arctic Ocean to the atmosphere. Underneath the surface, water temperatures are much higher than they used to be and, as around this time of year the Arctic Ocean freezes over, less heat will from now on be able to escape to the atmosphere. Sealed off from the atmosphere by sea ice, greater mixing of heat in the water will occur down to the seafloor of the Arctic Ocean.

As land around the Arctic Ocean freezes over, less fresh water will flow from rivers into the Arctic Ocean. As a result, the salt content of the Arctic Ocean increases, making it easier for ice in cracks and passages in sediments at the seafloor of the Arctic Ocean to melt, allowing methane contained in the sediment to escape. Furthermore, the sea ice makes that less moisture evaporates from the water, which together with the change of seasons results in lower hydroxyl levels at the higher latitudes of the Northern Hemisphere, in turn resulting in less methane being broken down in the atmosphere over the Arctic.

This situation will continue for months to come. Salty and warm water (i.e. warmer than water that is present in the Arctic Ocean) will continue to be carried by the Gulf Stream into the Arctic Ocean, while less heat and moisture will be able to be transferred to the atmosphere.

In conclusion, high methane levels threaten to further accelerate warming in the Arctic, in a vicious cycle escalating into runaway warming and resulting in death, destruction and extinction at massive scale.

So, what can be done to reduce the risk?

Climate Plan

- Emission Cuts

It is imperative that large emissions cuts are made quickly. The Climate Plan calls for 80% emission cuts by 2020, as one of multiple lines of action that need to be implemented in parallel.

- Greenhouse Gas Removal and Storage

The IPCC points at the need for carbon dioxide removal and also warns about ocean warming continuing for centuries (text below).

Indeed, even if all emissions by people could somehow be brought to an abrupt end, this alone will not stop the rise of ocean temperatures, at least not for a long time. For starters, air temperatures would start rising within days, in response to the disappearance of aerosols that now mask the full wrath of global warming. Furthermore, such a temperature rise would further accelerate feedbacks such as snow and ice decline, methane hydrate destabilization, etc., in turn feeding further temperature rises.

The Climate Plan therefore calls for carbon dioxide removal, as well as for active removal of other greenhouse gases from the atmosphere, and for further lines of action.

- Further Action

Again, merely implementing the above lines of action will not suffice to quickly bring down ocean temperatures. Paleo-climate records show that falls in temperature go hand in hand with falls of carbon dioxide in the atmosphere to levels under 280 ppm, as opposed to current carbon dioxide levels that are around 400 ppm.

Raising Funding for Further Action

The Climate Plan calls for comprehensive and effective action that includes additional lines of action. Such additional action will require U.N. supervision, which may make it hard for the necessary action to obtain sufficient funding.

In earlier posts, it was suggested that, besides having fees imposed on facilities that burn fossil fuel and on sales of fossil fuel itself, additional fees could be imposed on commercial international flights. As long as it seems too hard to substantially reduce emissions associated with such flights, it seems appropriate to explore further ways to minimize such flights, e.g. by imposing additional fees that could help fund further action.

There are a number of ways such fees could be implemented. Such fees could be calculated based on the distance traveled or as a percentage of the fare.

Fees could also be calculated on the basis of the traveler's flying history, e.g. in the form of frequent flyer fees. Such fees could be collected either by the respective airline or airport.

In the box on the right, Ekta Kalra gives further details about how the latter idea could be implemented.

What do you think?

Climate Accord New York September 2014

Under the Obama administration, the U.S. has made some (small) progress limiting the amounts of greenhouse gases that states emit, e.g. through Environmental Protection Agency limits on carbon dioxide emitted by power plants.

Given that greenhouse gases do spread all over the globe, the U.S. must also support action abroad to reduce levels of greenhouse gases.

At the upcoming Climate Summit in New York, September 23, President Obama will have a good opportunity to do so.

President Obama can and should support an accord for nations to jointly commit to bold action, including the imposition of fees on fossil fuel exported to nations that fail to commit to such action.

Where necessary, World Trade Organization rules should be agreed to be adjusted in order to accommodate such fees.

An accord on export fees can help U.S. exporters remain competitive and avoid repercussions. Such fees will also help make importing nations impose fees domestically, as they will not want to miss out on the revenues from such fees.

Revenues from such fees are best held in a trust fund and they are best used exclusively to finance international projects, such as efforts to save the sea ice in the Arctic and R&D into ways to decompose methane. As more nations impose fees domestically and accept responsibility to participate in international projects, such export fees can phase themselves out.

The People's Climate March will take place on September 21, starting 11:30 am from Central Park West (between 65th and 86th streets). Whether or not you're taking part in the march, consider supporting the Climate Plan. If you print out above image, you could make a cardboard sign. Over the coming days, photos of people holding up such a sign can be posted and shared at facebook and, if you add some lines saying you like the idea, they will be considered for display at the Arctic-news blog. You can also make it your profile picture on facebook during the remainder of the month to get a chance to be mentioned as a supporter.  Thanks in advance.

No new laws needed for President Obama to act

For anyone attending the September 23, 2014, Climate Summit in New York, it is important to bring the message that, while Congress may seek to deny the physical and legal realities, President Obama can and should act on climate change.

As you know, Sam Carana advocates comprehensive and effective action as discussed at the Climate Plan blog. You can share the message on facebook by clicking on the image below.

Act now on methane

by Malcolm Light

This is an extract. The full paper including figures and tables is at:   https://sites.google.com/site/runawayglobalwarming

Methane concentrations in the Arctic are higher than elsewhere in the world, as shown on figure 1. below (NASA image).

Methane is entering the atmosphere at high latitudes and spreading across the globe from there.

What is causing methane to be released in large quantities in the Arctic?

The Gulf Stream, pictured on figure 3. below, is warming up more than usual due to global warming. Specifically, pollution clouds pouring eastwards from the coast of Canada and the United States are the main culprit in heating up the Gulf Stream.

Figure 3. The Gulf Stream

In July 2013, water off the coast of North America reached 'Record Warmest' temperatures and proceeded to travel along the Gulf Stream to the Arctic Ocean, where it is now warming up the seabed. Figure 4. below further shows that above-average temperatures were recorded in July 2013 along the entire path of the Gulf Stream into the Arctic Ocean. 

Figure 4. NOAA: part of the Atlantic Ocean off the coast of North America reached record warmest temperatures in July 2013

The mean speed of the Gulf Stream is 4 miles per hour (6.4 km/hour or 1.78 metres/second), but the water slows down as it travels north. In the much wider North Atlantic Current, which is its north eastern extension, the current flows 3.5 times slower (about 0.51 metres/second), while the West Spitzbergen Current (WSC on figure 5. below) flows at about 0.35 metres/second (5 times slower).

The West Spitzbergen Current dives under the Arctic ice pack west of Svalbard, continuing as the Yermak Branch (YB on above map) into the Nansen Basin, while the Norwegian Current runs along the southern continental shelf of the Arctic Ocean, its hottest core zone at 300 metres depth destabilizing the methane hydrates en route to where the Eurasian Basin meets the Laptev Sea, a region of extreme methane hydrate destabilization and methane emissions. Figure 6. below, from an earlier post by Malcolm Light, shows how warm water flows into the Arctic Ocean and warms up methane hydrates and free gas held in sediments under the Arctic Ocean.

Sediments underneath the Arctic Ocean hold vast amounts of methane. Just one part of the Arctic Ocean alone, the East Siberian Arctic Shelf (ESAS, see figure 7. below), holds up to 1700 Gt of methane. A sudden release of just 3% of this amount could add over 50 Gt of methane to the atmosphere, and experts consider such an amount to be ready for release at any time.

Figure 7.

As above figure 7. shows, the total methane burden in the atmosphere now is 5 Gt. The 3 Gt that has been added since the 1750s accounts for almost half of all global warming. The amount of carbon stored in hydrates globally was in 1992 estimated to be 10,000 Gt (USGS), while a more recent estimate gives a figure of 63,400 Gt (Klauda & Sandler, 2005). The ESAS alone holds up to 1700 Gt of methane in the form of methane hydrates and free gas contained in sediments, of which 50 Gt is ready for abrupt release at any time, and Whiteman et al. calculate that an extra 50 Gt of methane would cause $60 trillion in damage. By comparison, the size of the world economy in 2012 was about $70 trillion. 

Smaller releases of methane in the Arctic come with the same risk; their huge local warming impact threatens to further destabilize sediments under the Arctic Ocean and trigger further methane releases, as illustrated by figure 8. below.

Figure 8.

Figure 9. below, from an earlier post by Malcolm Light, shows that, besides the shallow methane hydrate regions in the ESAS, the Arctic Ocean slope and deep water regions contain giant volumes of methane hydrate deposits (methane frozen within the ice).

If only a few percent of this methane hydrate becomes destabilized, it will release enough methane into the atmosphere to cause a Permian Age-type massive extinction event. Recent methane emission maps show that, besides the emissions from the ESAS, huge amounts of methane are being released from other parts of the Arctic Ocean.

We now know that the subsea methane hydrate is destabilizing at a fast-increasing pace and the pattern of destabilization indicates that it is mainly caused by the increasingly hot "Gulf Stream" waters entering the Arctic west of Svalbard and through the Barents Sea. These "Gulf Stream" waters do a complete circuit in the Arctic, even under a complete floating ice cover, and will destabilize the methane hydrates they come in contact with before making an exit along the edges of Greenland. Methane is now also emerging from the waters of the Greenland coastline, where the southward-bound "Gulf Stream" waters exit the Arctic Ocean along the edges of Greenland.

Historically, methane has caused delayed temperature anomalies of some 20°C, according to ice core analysis data, i.e. much higher than anomalies caused by carbon dioxide. Methane has a very high warming potential compared to carbon dioxide. Over a decade, methane's global warming potential is more than 100 times as much as carbon dioxide, while methane's local warming potential can be more than 1000 times as much. As a result, giant zones of circulating warm air in the Arctic have temperature anomalies in excess of 20°C.

Figure 10. [ click on image to enlarge ]

These hot clouds, resulting from many feedbacks including this Arctic atmospheric methane build-up, show that methane's delayed temperature anomaly of 20°C has already caught up in the Arctic and is going to progressively spread around the world resulting in runaway global warming.

Figure 11. [ click on image to enlarge ]

Above figure 11. (by Sam Carana) and figure 12. below (by Malcolm Light) indicate that the critical mean atmospheric temperature anomaly of 8°C will be reached between 2035 and 2050. At this temperature we can expect total deglaciation and extinction, according IPCC AR4 (2007).

By 2012, the mean atmospheric temperature had increased by some 0.8°C by human induced global warming. This year however Australia has seen an anomalous 0.22°C temperature increase. The new Australian temperature gradient implies that in ten years the atmosphere will be 2.2°C hotter and in 30 to 40 years, 6.6 to 8.8°C hotter which is consistent with the Arctic methane emission temperature increase curves of Carana and Light.

The reason for this sudden temperature increase in Australia this year is due to the fast building pall of methane in the Northern Hemisphere caused by global warming and destabilization of the subsea Arctic methane hydrates and the Arctic surface methane hydrate permafrosts.

At the moment, the entire Arctic is covered by a widespread methane cloud, but it is very concentrated (> 1950 ppb) over the Eurasian Basin and Laptev Sea where the subsea methane hydrates are being destabilized at increasing rates by heated Atlantic (Gulf Stream) waters. The area of the Eurasian Basin is similar to that of the East Siberian Arctic Shelf (ESAS) where Shakova et al. (1999) have shown that some 50 billion tons of methane could be released at any moment during the next 50 years from destabilization of subsea ESAS methane hydrates.

Figure 13.  Methane over the Arctic Ocean on December 3, 2013        [ click on image to enlarge ]

At the moment, water saturated with methane is traveling underneath the ice carried by exit currents and emerging at locations where the sea ice is still less than one meter thick, such as in Baffin Bay and in Hudson Bay, as also shown on the animation below.

This massive volume of methane entering the atmosphere will produce catastrophic consequences for the global climate system. Furthermore global warming is now destabilizing methane hydrates in the Eurasian Basin even more than on the ESAS. The release of an additional 50 billion tons of methane or more from the Eurasian Basin over the next 50 years will further compound the catastrophe represented by the destabilization of methane hydrates on the ESAS. Essentially we have passed the methane hydrate tipping point and are now accelerating into extinction as the methane hydrate "Clathrate Gun" has begun firing increasingly large volleys of methane into the Arctic atmosphere.

The growth of the mean atmospheric temperature using the curves on figure 12 indicate that the mean atmospheric temperature anomaly will exceed 1.5°C in 15 years and 2°C in 20 years, at which time storm systems will be very extreme with droughts, flooding, sea level rise and the loss of Pacific islands. When the mean atmospheric temperature anomaly reaches 8°C some 39 years in the future, there will be total deglaciation and a major extinction event that will culminate in a Permian-type extinction of all life on Earth.

If we do not stop the massive increases of Arctic methane emissions into the atmosphere the oceans will begin to boil off by 2080, when the mean temperature anomaly exceeds 115 to 120°C and the temperatures will be like those on Venus by 2100 (see figure 12).

The present end of the financial crisis and recovery of the U.S. economy will take us down the same fossil fuel driven road to catastrophe that the U.S. has followed before, when they refused to sign the original Kyoto Protocols. Unless the United States and Canada reduce their extreme carbon footprints (per unit population), they will end up being found guilty of ecocide and genocide, as the number of countries destroyed by the catastrophic weather systems continues to increase.

The United States and Canada seek to expand their economies by increasingly frenetic extraction of fossil fuels, using the most environmentally destructive methods possible (fracking and shale oil), while the population's total addiction to inefficient gas transport is leading our planet into suicide. We are like maniacal lemmings leaping to their deaths over a global warming cliff. What a final and futile legacy it will be for the leader of the free world to be remembered only in the log of some passing alien ship recording the loss of the Earth’s atmosphere and hydrosphere after 2080 due to human greed and absolute energy ineptitude.

The U.S. Government and Canada must ban all environmentally destructive methods of fossil fuel extraction such as fracking, extracting shale oil and coal and widespread construction of the now found to be faulty hydrocarbon pipeline systems. All Federal Government subsidies to fossil fuel corporations, for fossil fuel discovery and extraction must be immediately eliminated and the money spent solely on renewable energy development, which will provide many jobs to the unemployed. All long and short range (high consumption) fossil fuel-powered transport must be electrified or converted to hydrogen and where the range is too large, electric vehicles (including electric trains and ships) must be used instead of fossil fuel-powered trucks or aviation means of transport. All the major work for this conversion (including railway construction) can provide a new and growing set of jobs for the unemployed. Nuclear power stations must continue to be used and should be converted to the safe thorium energy system until the transition is complete.

The U.S. has to put itself on a war footing, but rather than fighting other military forces, it should recall its military forces from various places across the world and set them to work on the massive shift to renewable energy that the country needs to undertake if it wishes to survive the fast approaching catastrophe. The threat now comes from Mother Nature, who has infinite power at her disposal and intends to take no prisoners when she will strike back hard over a very short, absolutely brutal, 30-to-40-year period which has already begun. I cannot emphasise more, how serious humanity’s predicament is and what we should try to do to prevent our certain final destruction and extinction in 30 to 40 years if we continue down the present path we are following.

Figure 14. 

Above action plan (figure 14.) includes efforts to move to a sustainable economy (part 1.) and efforts to reflect and divert heat away from the Arctic (part 2.). Furthermore, it includes action on methane escaping from hydrates in the Arctic (part 3.), as described at the Arctic methane management page. Two types of methane management are further discussed below.

Arctic Methane Permanent Storage

In the ANGELS Proposal, subsea Arctic methane is extracted, stored and sold as LNG for distribution as fuel, to produce fertilizer, etc. Permanent storage underground, however, is more preferable.

Figure 15. 

As described by Sam Carana in an earlier post, Prof. Kenneth Yanda, at the University of California, Irvine, has shown that methane can be stored in propane - methane hydrates that are stable at temperatures of ca 15°C and low pressure (25 pounds per square inch - 1.66 atmospheres), very close to the ambient temperature and pressure conditions.

uptake. Each site is connected to three other sites (yellow

Hydrates can be produced that contain larger cages for other gases and smaller cages for methane.

Methane can be converted into propane and other gases with UV light and the final goal would be long-term storage of these gases in the form of hydrates in deep waters such as those north of Alaska, suggests Sam Carana, adding that carbon dioxide can also then be sequestered in the hydrates, after its removal from the atmosphere.

Unlike carbon dioxide, methane is completely non-polar and reacts very weakly with most materials.

Three zeolite types (SBN, ZON and FER) have been found to absorb methane at high to moderate rates (Figure 17, from Lawrence Livermore National Laboratory (LLNL) and UC Berkley, 2013).

These materials can help limit escape of fugutive gases from extraction, transport and distribution of methane.

Lucy and Alamo Projects

The Lucy project seeks to decompose methane in the atmosphere.

In a new modified version of the Lucy Project, hydroxyls can also be generated by a polarized 13.56 MHZ beam intersecting the sea surface over the region where a massive methane torch (plume) is entering the atmosphere, so that the additional hydroxyl will react with the rising methane breaking a large part of it down. The polarized 13.56 MHZ radio waves will decompose atmospheric humidity, mist, fog, ocean spray, and the surface of the waves themselves in the Arctic Ocean into nascent hydrogen and hydroxyl (figure 18).

The newly determined atmospheric temperature gradient indicates that the mean global atmospheric temperature will reach 1.5°C in 15 years and 2°C in 20 years (Figure 14). Consequently we only have 15 years to get an efficient methane destruction radio - laser system designed, tested and installed (Lucy and Alamo (HAARP) Projects, figure 18) before the accelerating methane eruptions take us into uncontrollable runaway global warming. This will give a leeway of 5 years before the critical 2°C temperature anomaly will have been exceeded and we will be looking at catastrophic storm systems, a fast rate of sea level rise and coastal zone flooding with its extremely deleterious effects on world populations and global stability.
