Wildfires in Russia's Far East

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
Wildfires can add huge amounts of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), nitrous oxide (N2O) and black carbon (BC or soot) into the atmosphere.

While CO and soot are not included as greenhouse gases by the IPCC, they can have strong warming impact. CO acts as a scavanger of hydroxyl, thus extending the lifetime of methane. BC results from biomass burning, which a study by Mark Jacobson found to cause 20 year global warming of ~0.4 K. Moreover, BC has a darkening effect when settling on snow and ice, making that less sunlight gets reflected back into space, which accelerates warming. This hits the Arctic particularly hard during the Northern Summer, given the high insolation at high latitudes at that time of year.

The image below shows fires around the globe on August 12, 2016.


Visible in the top right corner of above image are wildfires in Russia's Far East. The image below zooms in on these wildfires.


The image below shows carbon dioxide levels as high as 713 ppm and carbon monoxide levels as high as 32,757 ppb on August 12, 2016, at the location marked by the green circle, i.e. the location of the wildfires in Russia's Far East.


As said, wildfires can also emit huge amounts of methane. The image below shows methane levels as high as 2230 ppb at 766 mb.


The magenta-colored areas on above image and the image below indicate that these high methane levels are caused by these wildfires in Russia's Far East. The image below shows methane levels as high as 2517 ppb at 586 mb.


Methane levels as high as 2533 ppb were recorded that day (at 469 mb), compared to a mean global peak of 1857 ppb that day.

Analysis by Global Fire Data found that the 2015 Indonesian fires produced more CO2e (i.e. CO2 equivalent of, in this case, CO2, CH4 and N2O) than the 2013 CO2 emissions from fossil fuel by nations such as Japan and Germany. On 26 days in August and September 2015, emissions from Indoniasian fires exceeded the average daily emissions from all U.S. economic activity, as shown by the WRI image below.


Methane emissions from wildfires can sometimes be broken down relatively quickly, especially in the tropics, due to the high levels of hydroxyl in the atmosphere there. Conversily, methane from wildfires at higher latitudes can persist much longer and will have strong warming impact, especially at higher latitudes.

Similarly, CO2 emissions from wildfires in the tropics can sometimes be partly compensated for by regrowth of vegetation after the fires. However, regrowth can be minimal in times of drought, when forests are burned to make way for other land uses or when peat is burned, and especially at higher latitudes where the growth season is short and weather conditions can be harsh. Carbon in peat lands was built up over thousands of years and even years of regrowth cannot compensate for this loss.

A recent study concludes that there is strong correlation between fire risk for South America and high sea surface temperatures in the Pacific Ocean and the Atlantic Ocean. This makes the current situation very threatening. As the image below shows, sea surface temperature anomalies were very high on August 12, 2016.

Sea surface temperature and anomaly. Anomalies from +1 to +2 degrees C are red, above that they turn yellow and white
Above image also shows that on August 12, 2016, sea surface temperatures near Svalbard (at the location marked by the green circle) were as high as 18.9°C or 65.9°F, an anomaly of 13.6°C or 24.4°F. These high temperatures threaten to melt away the Arctic's snow and ice cover, resulting in albedo changes that accelerate warming, particularly in the Arctic. Warming of the Arctic Ocean further comes with the danger that methane hydrates at its seafloor will destabilize and make that huge amounts of methane will enter the atmosphere.

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

Olivine weathering to capture CO₂ and counter climate change - by R.D. Schuiling


Abstract

CO₂ is emitted in large quantities as a consequence of our burning of fossil fuels. It has several unpleasant consequences, because it will probably cause climate change, and there are several reports that high levels of CO₂ in offices and schools may impair the quality of thinking of the people that work there. Although higher levels of it in the atmosphere may also have some beneficial effects on vegetation, it should be considered as a possibly dangerous pollutant.

Introduction


Many new technologies are proposed to remove CO₂ from the atmosphere, but strangely enough the only process that has always removed the excess of CO₂ emitted by volcanoes since the origin of the Earth is barely considered. It is the weathering of minerals by which almost all the CO₂ that was emitted during the past by volcanoes was transported as bicarbonate solutions to the oceans where it was sustainably stored as carbonate rocks (limestones and dolomites).
Mg₂(SiO₄)  + 4 CO₂ + 4 H₂O 2 Mg2+ + 4 HCO3- + H₄(SiO₂)

These rocks contain about 1 million times more CO than the oceans, the atmosphere and the biosphere combined. It has provided a livable atmosphere, in contrast with Venus, where weathering was impossible due to the lack of liquid water. At present the CO levels in the atmosphere are rising, because the anthropogenic emission of CO is so large that this weathering process cannot keep pace with it. I propose to use a process of enhanced weathering to regain a new balance between input and output. In order to make this cost-effective, my examples will all represent a combination of CO capture with another beneficial effect, by which the total effect is cheaper, and may occasionally even lead to a positive financial result.

Ten cost-effective applications of olivine weathering:
  1. Increasing rice production by spreading olivine grains in paddies
  2. Olivine spreading on acid soils instead of liming
  3. Biogas production with additional methane production
  4. Solution of the sick-building syndrome of schools and offices
  5. The use of the surf as a huge ball-mill
  6. Diatom cultivation for the production of biodiesel
  7. Phytomining of nickel from olivine-rich soils
  8. Olivine hills to produce healthy mineral water
  9. Quenching forest fires with a serpentine slurry
  10. Tackling natural emissions in Milos, Greece

1. Increasing rice production by spreading olivine grains in paddies

Rice, like the other “wet grasses” like bamboo and reed needs silica. This is made available by spreading olivine grains over the paddies. It is very easy to measure the effects, by sampling the irrigation water where it enters the paddy, and sample it again where the water leaves the paddy containing olivine. The difference between the two analyses represents the effect of the weathering of the olivine. Rice production is negatively affected by acid conditions (1), and the weathering of olivine makes conditions more alkaline. As rice cultivation occupies 146 million hectares, spreading these annually with 4 ton of olivine per hectare also represents a sizable capture of CO. The increase of rice production can be measured by spreading for example 1, 3 and 10 ton of olivine over 3 paddies, and compare rice production with the production of a similar paddy without olivine spreading.

2. Olivine spreading on acid soils instead of liming

The approach as sketched above for rice can be extended to other acid agricultural soils as well. Normally acid soils are remediated by liming, but olivine spreading can do the same, and captures CO at the same time, whereas liming has a penalty for its CO emissions on account of the mining, milling and transporting of lime. Tests at the Agricultural University of Wageningen (2) have shown that olivine application increases productivity. The costs of adding lime or olivine will be rather similar, and soil scientists should decide whether a mixture of the two produces a better soil than using only one of the two.

3. Biogas production with additional methane production

Increasing methane production in biogas installations. In the normal operation of biodigesters, the produced gas contains roughly 2/3 methane, 1/3 CO and traces of HS. Before this gas can be added to the national gas lines, the CO content must be drastically reduced by rather expensive operations, and the HS must be removed. Tests with digesters have shown that the addition of fine-grained olivine has 3 important effects. It creates more alkaline conditions, which make that a larger part of the CO is already taken up as bicarbonate in the digestate, and does not have to be removed by expensive technologies. The second effect is that the traces of HS react with the iron content of the olivine and forms solid iron sulfide particles (olivine is a mixed crystal of Mg(SiO) and Fe₂(SiO₄). The third effect was somewhat unexpected. The methane production increases by the following reaction:

6 Fe₂(SiO₄) + CO₂ + 14 H₂O  Fe₃O₄ + CH₄ + 6 H₄(SiO₂)

The methane reaction is catalyzed by the tiny magnetite crystals that form in this reaction. In view of the important role of iron in the olivine, it may be worthwhile to look for olivine deposits with a higher Fe-content than the usual olivine. This application will reduce the costs of the digestion, and increase its production.

4. Solution of the sick-building syndrome of schools and offices

It was recently found by research groups in Berkeley and Harvard (3,4) that the high CO content of the internal atmosphere of these buildings (rising to 1500 to 1600 ppm in the afternoon compared to 400 ppm in the atmosphere outside) impaired the quality of thinking of the inmates. To avoid this, one can open doors and windows, but in temperate climates this causes serious increases in energy costs, and will often cause dust and noise problems. One can prevent this by installing a so-called CATO-reactor (Clean Air Through Olivine). This is a trough-like basin filled with an emulsion of fine olivine grains. Along the bottom a perforated pipe is installed, through which the internal atmosphere of the building is transported under a slight overpressure. The air bubbles pass through the olivine emulsion, and the CO is converted to bicarbonate in solution. This set-up has the additional advantage that it will also trap allergenic particles or pollen, which will make life easier for people who suffer from asthma or hay fever.

5. The use of the surf as a huge ball-mill

The surf as the largest ball-mill on Earth. Milling of olivine (around 2 US$/ton for milling olivine to 100 micron) is a cost that can be avoided if nature provides a zero cost alternative. We have carried out experiments with angular coarse olivine grit in a simulated very modest surf (5). After a few days the grains were rounded and polished grains (Fig. 1). Tiny micron-sized slivers were knocked off by collisions and abrasion. These slivers weathered in a few days.

Fig 1: The surf turns angular coarse olivine grit into rounded and polished grains in a few days
Depositing coarse olivine grit directly on beaches in the surf may well become the cheapest large-scale way to capture CO and restore the pH of the oceans.

6. Diatom cultivation for the production of biodiesel

Diatom cultivation for biodiesel production. Biofuels are produced at fairly large scale from oil palms, sorghum, maize and the like. This production occupies large tracts of land, which are withdrawn from the world food production. They consume large volumes of irrigation water, and use expensive fertilizer. Moreover not seldomly reservations for threatened animals, like the orang outan are used for these plantations. Enough reasons to look for different solutions. Diatoms (silica algae) are rich in organic material from which biodiesel can be produced. They are called silica algae, because their exoskeleton is made of silica. They can multiply fast, provided that they have enough silica. This can be provided by the weathering of olivine. One can think of the following solution for diatom cultivation. Create a lagoon along the beach, by surrounding a piece of the sea in front of this beach by a dam. Construct a connection through this dam, through which water can flow into the lagoon at high tide, and flow out of the lagoon at ebb tide. Cover the beach with half a meter thick layer of olivine grains between the high tide line and the low tide line. This beach will alternatively be wetted and drained, by which the silica-rich water will flow into the lagoon, and feed the diatoms. The dead diatoms must be harvested, dried and transported to the biodiesel plant . The diatom production in the lagoon can be boosted by installing an underwater led lighting, which makes that the photosynthesis of the diatoms can continue through the night.

7. Phytomining of nickel from olivine-rich soils

Phytomining of nickel. Olivine contains more nickel than most rocks, but still much lower than nickel ores. There are a number of plant species that have the strange habit that they can extract nickel very well from the soils on olivine rock and store it in their tissues . When you harvest these plants at the end of the growing season, dry them and burn them, the plant ash often contains around 10% of nickel, more than the richest nickel ore. Mining is an energy-intensive affair and has a high CO emission. Moreover the mining and the metal extraction from the ore cause a lot of pollution. This makes it tempting to see if you can use these nickel hyperaccumulator plants to do the job of mining without large CO emissions (6). Figure 2 shows the flowering Alyssum plants (a well-known nickel hyperaccumulator plant) on the tailings of an asbestos mine in Cyprus.

Fig 2: Yellow blossomed Alyssum nickel hyperaccumulator plants grow on tailings of former asbestos mine on Cyprus
8. Olivine hills to produce healthy mineral water

Olivine hills to produce healthy mineral water. When olivine weathers, it turns the water into a healthy magnesium bicarbonate water. According to the FAO such waters are active against cardiovascular diseases. This makes it interesting to see if we can produce similar mineral waters in places where there is no olivine in the subsoil. This is possible by the use of olivine hills (7). These can be constructed as follows. First make an impermeable layer on the soil in the form of a very flat slightly inclined gutter. Cover this with a hill of olivine grains of several meter thickness. Add soil over this hill, and plant it with shrubs and grasses. Soils are much richer in CO than the atmosphere. This is caused by the decay of dead plant material which produces CO in the soil, as well as the breathing of animals living in this soil. When it rains, the water will first encounter this CO-rich soil atmosphere, equilibrate with it and become aggressive. This CO-rich water will then move into the olivine layer, and react with it, producing a healthy magnesium bicarbonate water. This will trickle through the olivine layer until it meets the impermeable base, where it will slowly trickle to the lowest point of the gutter, where it will be released through a tap, where visitors can collect some of this water and drink it.

9. Quenching forest fires with a serpentine slurry

Quenching forest fires with a serpentine slurry. Forest fires cause the largest emission of CO after the emission by burning fossil fuels (8). Large forest fires lead to a number of deaths. Both from the public health side as from the CO emission side it would be helpful if we found a better way to quench forest fires rapidly. The following seems to be a promising way to achieve this. Serpentine is the hydrated form of olivine, it is similar to clay minerals. It is well-known that baking clays to make bricks consume a lot of energy. This is an unpleasant property, except where it is important to remove as much heat as possible, like in forest fires. We carried out a number of tests to see whether spreading serpentine slurries over fires would be a more effective way to quench fires than just water. This turned out to be very clearly the case, but not for the reason we thought. Test fires were extinguished in a few seconds when serpentine slurries were sprinkled over them, but the removal of excess heat was only a minor factor in the success. When serpentine slurries are spread over burning wood, the serpentine immediately dissociates, and forms a thin amorphous layer on the burning material. Oxygen can no longer come in contact with the burning wood, and inflammable gases from the burning wood can no longer escape. Test fires were quenched in a few seconds. As serpentinites are very common rocks, it should be easy to introduce this way of quenching to combat forest fires. It is hoped that this will be introduced by the fire brigades in many countries that suffer from forest fires, and thus save unnecessary deaths and destruction of properties. The amorphous product of the serpentine after it has reacted in the fire reacts quite fast with the first rains, faster than olivine, and thus compensates part of the CO₂ that was emitted by the fire.

10. Tackling natural emissions in Milos, Greece

CO₂ levels in the atmosphere are rising, because we are burning in a few hundred years the fossil fuels (coal, oil, gas) that have taken hundreds of millions of years to form. This will probably cause a climate change, with disastrous world problems, because the ice in Greenland and Antarctica will melt and cause a serious sealevel rise. It is important, therefore, to capture as much CO₂ as possible and store it in a safe and sustainable manner.

It makes no difference for the climate if we capture anthropogenic CO₂ or natural CO₂ emissions, because all CO₂ molecules are identical. The anthropogenic emissions are much more voluminous, but natural emissions are easier to capture. An excellent example is found on and around the island of Milos, where annually 2.2 million tons of hot CO₂ are emitted from a surface area of about 35 km². The village of Paleochori is the center of this CO₂ emission. Most of the CO₂ emission is by bubbles rising out of the shallow seafloor, but CO₂ is also emitted on land. When you try to dig a hole in the beach with your hands, you have to stop when the hole is elbow-deep, otherwise you burn your hands. The bubbles are so hot, that a local restaurant in Paleochori is even using it for its “volcanic cooking”. They have buried a box in the beach sand, in which they cook a lamb every morning. Delicious to have a juicy lamb for lunch on the terrace of that restaurant, while you look out over the blue Aegean.

It becomes important for the world to capture as much CO₂ as possible. When you apply this to the CO₂ emissions at Milos, one could do the following. First find a place where the most CO₂ bubbles rise from the shallow sea floor. Then make a small artificial island by covering this point with a hill of olivine sand as well as larger olivine pieces. Of course, when bubbles of CO₂ rise in the sea, they will assume the same temperature as the sea water, but if they rise in an olivine hill they will cause the temperature inside that olivine hill to rise, because now the hot bubbles release their heat to the surrounding olivine grains. This situation will lead to a small convection system. The warm water inside the hill will start to rise, and cold seawater will be sucked in the hill from the sides. If one constructs a shallow pit on top of the island, it will fill with warm water.

Would it not be an exotic temptation for tourists, to lie even in winter in a warm bath on top of a small island, and look out over a cool blue sea? They will feel even better if they know that these delicious sensations are a small part of our efforts to save the world from climate change, and the seas from acidification. The reaction of the olivine with water + CO₂ is exothermic, so that provides some additional heat for the water in the bath.

Additional information:

As said, the weathering reaction of olivine with water and CO2 is as follows:
Mg₂(SiO₄)  + 4 CO₂ + 4 H₂O  2 Mg2+ + 4 HCO3- + H₄(SiO₂)

This means that the greenhouse gas CO₂ is converted to a bicarbonate solution, so it is no longer affecting the climate.

Some possible sources of olivine in Greece

Olivine is a very common mineral. The tailings of a magnesite company in northern Greece contain close to ten million tons of crushed olivine. A port is not too far from the location of that magnesite mine. Nearer by, on the island of Naxos, there are quite a few places with olivine rocks at the surface, where the material could be obtained by a small open pit digging operation. Apart from the proposal as a touristic attraction, Greece can present it as one of their attempts to sustainably capture the greenhouse gas CO₂.

Conclusion

Removal of CO₂ from the atmosphere can be combined in a number of ways with other positive effects, which makes such operations considerably more cost-effective.

Arctic Climate Records Melting

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
An intensely warm winter and spring are melting climate records across Alaska, reports NOAA in the post 'Arctic set for record-breaking melt'. The January-April 2016 period was 11.4°F (6.4°C) warmer than the 20th century average, reports NOAA. The NOAA image below further illustrates the situation.
The sea ice is melting rapidly. Warm water from the Mackenzie River contributes to dramatic melting in the Beaufort Sea, as illustrated by the image below, showing that on May 20, 2016, the Arctic Ocean was 5°F (2.8°C) warmer than in 1981-2011 at the delta of the Mackenzie River.


The image below shows that on May 20, 2016, sea ice extent was 10.99 million square km, compared to the 12.05 million square km extent of the sea ice in May 20, 2012, as measured by JAXA


Sea ice reached a record minimum extent of 3.18 million square km on September 15, 2012, and chances are that the sea ice will be largely gone by September 2016.

The year 2016 is an El Niño year and insolation during the coming months of June and July is higher in the Arctic than anywhere else on Earth. Higher temperatures come with increased danger of wildfires. Greenhouse gases are at record high levels: in April and may, CO2 was about 408 ppm, with hourly peaks as high as 411 ppm (on May 11, 2016). Methane levels are high and rising, especially over the Arctic. Smoke and methane are speeding up sea ice melting, as illustrated by the image below showing smoke from wildfires in Canada extending over the Beaufort Sea (main image), in addition to high methane levels that are present over the Beaufort Sea (inset). 


Ocean heat is also very high and rising. Oceans on the Northern Hemisphere were 0.93°C (or 1.7°F) warmer in the most recent 12-months period (May 2015 through April 2016) than the 20th century average.

The image below shows sea ice extent as measured by the NSIDC, confirming that melting of the sea ice in 2016 is way ahead on previous years.



Here's an animation comparing sea surface temperatures of the North Atlantic between May 25, 2015, and May 25, 2016.


Arctic sea ice extent was 10.7 million km2 on May 25, 2016, 1.1 million km2 less than it was on May 25, 2012, as the update below shows.



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


Wildfire Danger Increasing

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
Wildfires are starting to break out in British Columbia, Canada. The wildfire on the image below started on May 1, 2016 (hat tip to Hubert Bułgajewski‎).


The coordinates of the wildfire are in the bottom left corner of above map. They show a location where, on May 3, 2016, it was 26.0°C (or 78.8°F). At a nearby location, it was 27.6°C (or 81.8°F) on May 3, 2016. Both locations are indicated on the map on the right.

These locations are on the path followed by the Mackenzie River, which ends up in the Arctic Ocean. Wildfires aggravate heat waves as they blacken the soil with soot. As the Mackenzie River heats up, it will bring warmer water into the Arctic Ocean where this will speed up melting of the sea ice.

Moreover, winds can carry soot high up into the Arctic, where it can settle on the sea ice and darken the surface, which will make that more sunlight gets absorbed, rather than reflected back into space as before.

The danger of wildfires increases as temperatures rise. The image on the right show that temperatures in this area on May 3, 2016 (00:00 UTC) were at the top end of the scale, i.e. 20°C or 36°F warmer than 1979-2000 temperatures.

Extreme weather is becoming increasingly common, as changes are taking place to the jet stream. As the Arctic warms up more rapidly than the rest of the world, the temperature difference between the Equator and the North Pole decreases, which in turn weakens the speed at which the north polar jet stream circumnavigates the globe.

This is illustrated by the wavy patterns of the jet stream in the image on the right, showing the situation on May 3, 2016 (00:00 UTC), with a loop bringing warm air high up into North America and into the Arctic.

In conclusion, warm air reaching high latitudes is causing the sea ice to melt in a number of ways:
  • Warm air makes the ice melt directly. 
  • Warmer water in rivers warms up the Arctic Ocean. 
  • Wildfires blacken land and sea ice, causing more sunlight to be absorbed, rather than reflected back into space as before.

The situation doesn't appear to be improving soon, as illustrated by the image on the right. Following the record high temperatures that hit the world earlier this year, the outlook for the sea ice looks bleak.

Further decline of the snow and ice cover in the Arctic looks set to make a number of feedbacks kick in stronger, with methane releases from the seafloor of the Arctic Ocean looming as a huge danger.

NSIDC scientist Andrew Slater has created the chart below of freezing degree days in 2016 compared to other years at Latitude 80°N. See Andrew's website and this page for more on this.
Below is a comparison of temperatures and emissions for the two locations discussed above. Such fires are becoming increasingly common as temperatures rise, and they can cause release of huge amounts of carbon dioxide, carbon monoxide, methane, sulfur dioxide, soot, etc.

The video below shows methane levels (in parts per billion or ppb) on May 3, 2016, pm, starting at 44,690 ft or 13,621 m and coming down to 5,095 ft or 1,553 m altitude. In magenta-colored areas, methane is above 1950 ppb.


In the video below, Paul Beckwith discusses the situation.


Wildfires are also devastating other parts of the Earth. Below is an image showing wildfires over the Amur River on May 7, 2016.


The image below shows carbon monoxide levels over the Amur River as high as 22,480 ppb on May 9, 2016. Hat tip to Grofu Antoniu for pointing at the CO levels. According to this Sputniknews report, a state of emergency was declared in the Amur Region as fires stretched across 12,200 acres.


The video below shows carbon monoxide emissions in eastern Asia from May 1 to May 26, 2016.

Meanwhile, the National Snow and Ice Data Center (NSIDC) has resumed daily sea ice extent updates with provisional data. The image below is dated May 5, 2016, check here for updates.

As illustrated by the image below, from JAXA, sea ice extent on May 6, 2016, was under 12 million square km, more than 15 days ahead on extent in the year 2012, which was 12 million square km on May 21, 2012.


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

Malcolm Light comments:

Most natural processes on the Earth are run by convection including plate tectonics that moves the continental and oceanic plates across the surface of the planet. Mother Earth has been able to hold its atmospheric temperature within certain limits and maintain an ocean for more than 3 billion years because each time there was a build up of carbon dioxide in the atmosphere which produced a global fever, Mother Earth it eliminated the living creatures with a massive Arctic methane firestorm that fried them alive. This giant Arctic methane firestorm is a natural antibiotic the Earth uses to rid itself of those creatures that have overproduced carbon dioxide and caused a global fever.

Essentially mankind has again caused a massive build up of fossil fuel carbon dioxide in the atmosphere and Mother Earth has already started to respond with the predicted massive Arctic methane blow out (since 2010) which will lead to an Earth engulfing firestorm in 5 to 8 years.

The giant fires in the Fort McMurray region are a result of atmospheric methane induced heating of the Arctic and 93.5% global warming of the oceans that has generated a massive El Nino event this year. Hot winds moving away from these high pressure areas have generated high temperatures and massive fires in Alberta which is a giant fever spot on Earth where mankind has produced the maximum amount of dirty fossil fuel extraction and pollution in Canada.

Mother Earth will continue to respond more vigorously with her Arctic methane antibiotic to eliminate the humans from her system as we represent nothing more to her than a larger version of an influenza virus which has seriously retarded her oceanic and atmospheric temperature range functioning systems.

If we do not immediately stop fossil fuel extraction worldwide and control the Arctic methane emission sites we will all be stardust before a decade is past.

Monthly CO2 Levels Above 400ppm

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online


For the first time since modern records began, monthly mean carbon dioxide levels were above 400 parts per million (ppm), as illustrated by the NOAA image below. NOAA just released the mean global carbon dioxide level for March 2015, which was 400.83 ppm.
Arctic Ocean hit hard

Carbon dioxide concentrations can be especially high, i.e. well over 410 ppm, at higher latitudes of the Northern Hemisphere, as illustrated by the NOAA image below. This can contribute to very high temperature anomalies over the Arctic Ocean and thus increase the risk of huge amounts of methane erupting from the Arctic Ocean seafloor.

Since the start of the Industrial Revolution, carbon dioxide levels have risen non-linearly, as illustrated by the image below.

Need for Comprehensive and Effective Action

As many posts at this blog have warned, emissions by people and the numerous feedbacks are threatening to push Earth into runaway global warming.

This calls for comprehensive and effective action to - among other things - reduce atmospheric carbon dioxide levels back to 280 ppm, as illustrated by the image below and as further discussed at the policies proposed as part of the Climate Plan.


How best to get back to 280 ppm? 

The Climate Plan calls for restoration of greenhouse gas levels in oceans and atmosphere to their long term average by 2100. In the Climate Plan, multiple lines of action are proposed to work simultaneously, in parallel and separately in their implementation, yet complementary in their impact.


One line of action is to cut emissions by 80% by the year 2020. To achieve this, the Climate Plan advocates implementation of local feebates. Especially important are fees on sales of fuel, while the resulting revenues are best used to fund rebates on products sold locally that further help speed up the shift to clean energy.

Without further action, much of the carbon dioxide that has been emitted will stay in the atmosphere for hundreds, if not thousands of years. Therefore, further lines of action are needed, including removal of carbon dioxide from the atmosphere and oceans, with the carbon being safely stored.

For the long term average of 280 ppm to be achieved in 2100, large amounts of atmospheric carbon dioxide must also be removed and safely stored annually. How much must be removed? The period from 2015 to 2100 has 85 years, so bringing down carbon dioxide from 400 ppm to 280 ppm over that period works out to an annual removal of 1.41 ppm. By comparison, this is slightly less than the annual growth in carbon dioxide levels as caused by people since 1959, which is on average 1.47 ppm. Assuming that emissions will not be cut quickly enough to avoid further build up of carbon dioxide in the atmosphere in the near future, annual removal will need to be somewhat more, so 1.47 ppm looks like a good target for now, precisely because it equals past emissions.


The Climate Plan thus proposes that each nation will contribute to the necessary annual 1.47 ppm removal with a share that reflects its past emissions. The image below gives an idea of past emissions. Note that the image only shows emissions up to the year 2011 and that they exclude land use change and forestry emissions. Furthermore, the image shows emissions based on where products were produced. Much of the rise in emissions is the result of products that were produced in Asia, yet many of these products were consumed in Europe and North America. Therefore, graphs based on emissions where products were consumed would paint a somewhat different picture. The Climate Plan proposes that a nation's contributions to carbon dioxide removal (from oceans and atmosphere) will reflect its past emissions based on where products were consumed.


The Climate Plan advocates separate lines of action, i.e. greenhouse gas removal next to emission cuts and further action. Keeping action on different types of pollution separate and calling for local action in each nation further helps avoid that progress elsewhere is pointed at by a nation as an excuse to delay the necessary action on a specific type of pollution in that nation.

As said, the Climate Plan therefore calls for fees to be added on sales of polluting products where they are consumed (as opposed to where they are produced). Each nation is further expected to take steps to contribute its share to the 1.47 ppm carbon dioxide that needs to be removed from the atmosphere annually. Additionally, carbon dioxide needs to be removed from the oceans.

The most important thing each nation can do in the lead-up to the upcoming U.N. climate conference in Paris is to accept these commitments. How each nation and local community does achieve targets is best decided locally, provided that each nation and each local community does indeed reach its targets, and this follows from this commitment.

One reason why local feebates are recommended is that they can focus on achieving local targets for a specific pollutant. Local feebates allow communities to quickly adjust the height of the fees, where a local community threatens to fail reaching a target. Such a local focus does not preclude action being beneficial elsewhere as well. Indeed, the same feebate can work for multiple pollutants and on multiple lines of action. In this sense, locally implemented feebates often work complementary. As an example, the feebates pictured below will help remove carbon dioxide from the atmosphere and oceans, while they will also help cut emissions of carbon dioxide, methane, soot and nitrous oxide.

It's time to 'Do the math' again

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
By David Spratt

Have we gone mad? A new report released today explains why contemporary climate change policy-making should be characterised as increasingly delusional.

As the deadline approaches for submissions to the Australian government's climate targets process, there is a flurry of submissions and reports from advocacy groups and the Climate Change Authority.

Most of these reports are based on the twin propositions that two degrees Celsius (2°C) of global warming is an appropriate policy target, and that there is a significant carbon budget and an amount of "burnable carbon" for this target, and hence a scientifically-based escalating ladder of emission-reduction targets stretching to mid-century and beyond.

A survey of the relevant scientific literature by David Spratt, "Recount: It's time to 'Do the math' again", published today by Breakthrough concludes that the evidence does not support either of these propositions.

The catastrophic and irreversible consequences of 2°C of warming demand a strong risk-management approach, with a low rate of failure. We should not take risks with the climate that we would not take with civil infrastructure.

There is no carbon budget available if 2°C is considered a cap or upper boundary as per the Copenhagen Accord, rather than a hit-or-miss target which can be significantly exceeded; or if a low risk of exceeding 2°C is required; or if positive feedbacks such as permafrost and other carbon store losses are taken into account.

Effective policy making can only be based on recognising that climate change is already dangerous, and we have no carbon budget left to divide up. Big tipping-point events irreversible on human time scales such as in West Antarctica and large-scale positive feedbacks are already occurring at less than 1°C of warming. It is clear that 2°C of climate warming is not a safe cap.

In reality, 2°C is the boundary between dangerous and very dangerous climate change and 1°C warmer than human civilisation has ever experienced.

In the lead up to the forthcoming Paris talks, policy makers through their willful neglect of the evidence are in effect normalising a 2.5–3°C global warming target.

This evidence in "Recount: It's time to 'Do the math' again" demonstrates that action is necessary at a faster pace than most policy makers conceive is possible.

350,000 Marchers = 50 Parts Per Million

People's Climate March, New York, September 21, 2014, photo by Cindy Snodgrass

How big a deal was the march in Manhattan yesterday? One of the organizers was 350.org, a group started by Bill McKibben based on a paper by climate scientist James Hansen which stated that we should aim for about 350 parts per million (ppm) CO2. We are currently at about 400ppm, so we need to move "only" about 50ppm in the opposite direction from our rapid growth, which hit a frightening 3ppm clip last year.

It will take a huge effort, and few alive today will live to see it (short of large-scale engineering), but it is interesting to ponder the minute change this represents in the air -- a shift of just 5 one-thousandths of one percent (.005 percent) of the atmosphere! That is one of the fascinating things in climate science, how such a minute change in our atmosphere could potentially have such an impact on the energy balance of our whole planet.

Keep this in mind if you are trying to contemplate how big a deal it is that some 350,000 people came out into the streets of Manhattan, the capital of capitalism, the cultural heart of the nation where manufactured denial has most stymied action. That's because this happens to be exactly the same proportion of the 7 billion members of humanity, 5 one-thousandths of one percent, as that 50ppm is a shift in the composition of the air. Further, some have estimated the real number of marchers as 400,000, and if the global estimates swell equally, then globally about the same proportion were marching as the CO2 growth since industrialization is a shift in atmospheric composition. In a way, all those marching were just a trace, and as soon as we dissipated into streets and subways afterwards, quickly outnumbered by people going about their everyday lives, that seemed obvious, but in another way, how monumental the right little trace can become!

And speaking of powerful little traces, methane is even far less concentrated in the air than CO2, about 220 times less so, but there was really some methane floating around the Manhattan air yesterday! No, I don't mean all those leaky pipes in the city that have led local tests to sometimes register incredibly high ambient readings of the greenhouse gas. I mean that among the marchers anti-fracking signs often seemed to outnumber all other "sub-theme" signs. This is a fascinating phenomenon, as some of us have felt that, since we all ultimately must live in the here and now, and since one cannot impact the climate we have here and now very effectively through CO2 mitigation, yet one can only gain practical political traction by dealing with that here and now, so one of the best ways to gauge seriousness in getting movement going on climate would be to watch for meaningful action on methane. In a sense, if you want people to start climbing up a very steep ladder, you need to give them a nice low first step, and that first climate step would be methane. As Robert Watson, the previous Chair of the United Nation's Intergovernmental Panel on Climate Change put it succinctly, rapidly cutting methane, "would demonstrate to the world that we can do something to quickly slow climate change. We need to get moving to cool the planet's temperature. Methane is the most effective place for us to start."

The Manhattan climate march also provided a fitting example of how getting the big slow march of change rolling can be frustrating: for those in the back it took two hours to start any movement at all, and then another two hours to reach Columbus Circle, its ostensible starting point. Similarly inevitable drags on climate mitigation are making rapid methane action all the more important. And uncertainties in near-term climate change, with a rising potential for high-impact lower-probability events to cause abrupt heating (like non-human methane emissions in the arctic taking off more quickly than models predict), means that ignoring the near-term climate for too long could ultimately prove fatal to all our best intentions. So it's fascinating to see an interest in methane growing from the grass roots, even if it is still largely (and erroneously) confined to the fracking issue at this point. Let's hope that the interest in this merest little trace gas of our air -- since industrialization it has risen by about 1.1 ppm, a shift of about 1.1 ten-thousandth of 1 percent of the atmosphere! -- sparks soon. The group 1250 was initially intended to provide a kind of autonomous offshoot to McKibben's 350, in order to help generate that spark, but McKibben himself soon said that he "had his hands full with CO2" and did not at the time send along to his followers the group's initial petition drive, which then quickly languished. But if methane interest does reach that critical concentration, and that spark is provided, you know what happens next: that's when climate action goes boom.
