A Global Temperature Rise Of More than Ten Degrees Celsius By 2026?

How much have temperatures risen and how much additional warming could eventuate over the next decade? The image on the right shows a potential global temperature rise by 2026 from pre-industrial levels. This rise contains a number of elements, as discussed below from the top down.

February 2016 rise from 1900 (1.62�C)

The magenta element at the top reflects the temperature rise since 1900. In February 2016, it was 1.62�C warmer compared to the year 1900, so that's a rise that has already manifested itself.

Rise from pre-industrial levels to 1900 (0.3�C)

Additional warming was caused by humans before 1900. Accordingly, the next (light blue) element from the top down uses 0.3�C warming to reflect anthropogenic warming from pre-industrial levels to the year 1900.

When also taking this warming into account, then it was 1.92�C (3.46�F) warmer in February 2016 than in pre-industrial times, as is also illustrated on the image below.

Warming from the other elements (described below) comes on top of the warming that was already achieved in February 2016.

Rise due to carbon dioxide from 2016 to 2026 (0.5�C)

The purple element reflects warming due to the amount of carbon dioxide in the atmosphere by 2026. While the IEA reported that energy-related carbon dioxide emissions had not risen over the past few years, carbon dioxide levels in the atmosphere have continued to rise, due to feedbacks that are kicking in, such as wildfires and reduced carbon sinks. Furthermore, maximum warming occurs about one decade after a carbon dioxide emission, so the full warming wrath of the carbon dioxide emissions over the past ten years is still to come. In conclusion, an extra 0.5�C warming by 2026 seems possible as long as carbon dioxide levels in the atmosphere and oceans remain high and as temperatures keep rising.

Removal of aerosols masking effect (2.5�C)

With dramatic cuts in emissions, there will also be a dramatic fall in aerosols that currently mask the full warming of greenhouse gases. From 1850 to 2010, anthropogenic aerosols brought about a decrease of ~2.53 K, says a recent paper. While on the one hand not all of the aerosols masking effect may be removed over the next ten years, there now are a lot more aerosols than in 2010. A 2.5�C warming due to removal of part of the aerosols masking effect therefore seems well possible by the year 2026.

Albedo changes in the Arctic (1.6�C) 

Warming due to Arctic snow and ice loss may well exceed 2 W per square meter, i.e. it could more than double the net warming now caused by all emissions by people of the world, calculated Professor Peter Wadhams in 2012. A 1.6�C warming due to albedo changes (i.e. decline of both Arctic sea ice and snow and ice cover on land) therefore seems well possible by the year 2026.

Methane eruptions from the seafloor (1.1�C)

". . we consider release of up to 50 Gt of predicted amount of hydrate storage as highly possible for abrupt release at any time," Dr. Natalia Shakhova et al. wrote in a paper presented at EGU General Assembly 2008. Authors found that such a release would cause 1.3�C warming by 2100. Note that such warming from an extra 50 Gt of methane seems conservative when considering that there now is only some 5 Gt of methane in the atmosphere, and over a period of ten years this 5 Gt is already responsible for more warming than all the carbon dioxide emitted by people since the start of the industrial revolution. Professor Peter Wadhams co-authored a study that calculated that methane release from the seafloor of the Arctic Ocean could yield 0.6�C warming of the planet in 5 years (see video at earlier post). In conclusion, as temperatures keep rising, a 1.1�C warming due to methane releases from clathrates at the seafloor of the world's oceans seems well possible by the year 2026.

Extra water vapor feedback (2.1�C)

Rising temperatures will result in more water vapor in the atmosphere (7% more water vapor for every 1�C warming), further amplifying warming, since water vapor is a potent greenhouse gas. Extra water vapor will result from warming due to the above-mentioned albedo changes in the Arctic and methane releases from the seafloor that could strike within years and could result in huge warming in addition to the warming that is already there now. As the IPCC says: "Water vapour feedback acting alone approximately doubles the warming from what it would be for fixed water vapour. Furthermore, water vapour feedback acts to amplify other feedbacks in models, such as cloud feedback and ice albedo feedback. If cloud feedback is strongly positive, the water vapour feedback can lead to 3.5 times as much warming as would be the case if water vapour concentration were held fixed", according to the IPCC. Given a possible additional warming of 2.7�C due to just two elements, i.e. Arctic albedo changes and seafloor methane, an additional warming over the next decade of 2.1�C due to extra water vapor in the atmosphere therefore does seem well possible by the year 2026.

Further feedbacks (0.3�C)

Further feedbacks will result from interactions between the above elements. Additional water vapor in the atmosphere and extra energy trapped in the atmosphere will result in more intense storms and precipitation, flooding and lightning. Flooding can cause rapid decomposition of vegetation, resulting in strong methane releases. Furthermore, plumes above the anvils of severe storms can bring water vapor up into the stratosphere, contributing to the formation of cirrus clouds that trap a lot of heat that would otherwise be radiated away, from Earth into space. The number of lightning strikes can be expected to increase by about 12% for every 1�C of rise in global average air temperature. At 3-8 miles hight, during the summer months, lightning activity increases NOx by as much as 90% and ozone by more than 30%. The combination of higher temperatures and more lightning will also cause more wildfires, resulting in emissions such as of methane and carbon monoxide. Ozone acts as a direct greenhouse gas, while ozone and carbon monoxide can both act to extend the lifetime of methane. Such feedbacks may well result in an additional 0.3�C warming by the year 2026.

Total potential global temperature rise by 2026 (10�C or 18�F)

Adding up all the warming associated with the above elements results in a total potential global temperature rise (land and ocean) of more than than 10�C or 18�F within a decade, i.e. by 2026. As said before, this scenario assumes that no geoengineering will take place over the next decade.

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

2016 Arctic Sea Ice Headed To Zero

The image below shows that Arctic sea ice extent on July 3, 2016, was 8,707,651 square km, i.e. less than the 8.75 million square km that extent was on July 3, 2012.

In September 2012, Arctic sea ice extent reached a record low. Given that extent now is only slightly lower than it was in 2012 at the same time of year, can extent this year be expected to reach an even lower minimum, possibly as low as zero ice in September 2016?

The ice this year is certainly headed in that direction, given that the sea ice now is much thinner than it was in 2012. The image below shows sea ice thickness on July 7, 2012, in the left-hand panel, and adds a forecast for July 7, 2016 in the right-hand panel.

Besides being thinner, sea ice now is also much more slushy and fractured into small pieces. The animation below shows that the sea ice close to the North Pole on July 4, 2016, was heavily fractured into pieces that are mostly smaller in size than 10 x 10 km or 6.2 x 6.2 miles. By comparison, sea ice in the same area did develop large cracks in 2012, but even in September 13, 2012, it was not broken up into small pieces.

One big reason behind the dire state the sea ice is in now is ocean heat. On July 2, 2016, sea surface near Svalbard (at the location marker by the green circle) was as warm as 16.7�C or 62.1�F, i.e. 13.5�C or 24.3�F warmer than 1981-2011. This gives an indication how much warmer the water is that is entering the Arctic Ocean.

As the sea ice disappears, less sunlight gets reflected back into space, resulting in additional warming of the Arctic Ocean. In October 2016, the sea ice will return, sealing off the Arctic Ocean, resulting in less heat being able to escape, at the very time the warmest water is entering the Arctic Ocean from the Atlantic and Pacific Oceans. The danger of this situation is that a large amount of heat will reach the seafloor and destabilize hydrates, resulting in huge abrupt methane releases that will further contribute to warming. When adding in further factors such as discussed e.g. at this earlier post, this adds up to a potential temperature rise of more than 10�C or 18�F compared to pre-industrial times in less than ten years time from now.

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

Climate Feebacks Start To Kick In More

Droughts and heatwaves are putting vegetation under devastating pressure while also causing wildfires resulting in deforestation and loss of peat at massive scale, contributing to the rapid recent rise in carbon dioxide levels. 

It will take a decade before these high recent carbon dioxide emissions will reach their full warming impact. Furthermore, as the world makes progress with the necessary cuts in greenhouse gas emissions, this will also remove aerosols that have until now masked the full wrath of global warming. By implication, without geoengineering occurring over the coming decade, temperatures will keep rising, resulting in further increases in abundance and intensity of droughts and wildfires.

Temperatures in the Arctic are rising faster than elsewhere. The image below shows that Arctic waters are now much warmer than in 2015. On June 22, 2016, sea surface near Svalbard was as warm as 13.8�C or 56.9�F (green circle), i.e. 11.6�C or 20.9�F warmer than 1981-2011.

High temperatures, as high as 34.1�C or 93.3�F at green circle, were recorded on July 1, 2016, over the Lena River which flows into the Laptev Sea, as illustrated by the image on the right [click on images to enlarge them].

Wildfires can release huge amounts of carbon dioxide (CO2), carbon monoxide (CO), methane and soot. The image below shows that on June 23, 2016, wildfires north of Lake Baikal caused emissions as high as 22,953 ppb CO and 549 ppm CO2 at the location marked by the green circle.

The video below, created by Jim Reeve, shows an animation with carbon monoxide levels in May 2016.

As increasing amounts of soot from wildfires settle on its ice and snow cover, albedo decline in the Arctic will accelerate. In addition, heatwaves are causing rapid warming of rivers ending in the Arctic Ocean, further speeding up its warming and increasing the danger of methane releases from the seafloor of the Arctic Ocean.

As more energy stays in the biosphere, storms can be expected to strike with greater intensity. Rising temperatures will result in more water vapor in the atmosphere (7% more water vapor for every 1�C warming), further amplifying warming and resulting in more intense precipitation events, i.e. rainfall, flooding and lightning.

Record-breaking daily rainfall events around the world. From Lehmann et al. 

Recently, West Virginia got hit by devastating flooding, killing at least 26 people and causing evacuation of thousands of people and a huge amount of damage. Flooding can also cause rapid decomposition of vegetation, resulting in strong methane releases, as illustrated by the image below showing strong methane presence (magenta color) at 39,025 ft or 11.9 km on June 26 (left panel), as well as at 44,690 ft or 13.6 km on June 27 (right panel).

Furthermore, plumes above the anvils of severe storms can bring water vapor up into the stratosphere, contributing to the formation of cirrus clouds that trap a lot of heat that would otherwise be radiated away, from Earth into space. The number of lightning strikes can be expected to increase by about 12% for every 1�C of rise in global average air temperature. At 3-8 miles hight, during the summer months, lightning activity increases NOx by as much as 90% and ozone by more than 30%.

In conclusion, feedbacks are threatening to cause runaway warming, potentially making temperatures rise by more than 10�C or 18�F within a decade. Already now, melting ice sheets are changing the way the Earth wobbles on its axis, Nasa says. As Paul Beckwith discusses in the video below, changes are also taking place to the jet streams.

The danger is that changes to the planet's wobble will trigger massive earthquakes that will destabilize methane hydrates and result in huge amounts of methane abruptly entering the atmosphere, as illustrated by the image below.

Have we lost the Arctic? It looks like Earth no longer has two poles, but instead has turned into a Monopole, with only one pole at Antarctica. On June 29, 2016, Arctic water (sea surface) was as warm as 15.8�C (60.5�F), or 13�C (23.4�F) warmer than 1981-2011. Meanwhile, surface temperatures over Antarctica that day were as low as -66.6�C (-87.8�F).

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

High Temperatures In Arctic

0-2000 m Global Ocean Heat Content

Ocean heat content is rising, as illustrated by the image on the right. Where the sea ice declines, this is causing high air temperatures in the Arctic.

This year (from January to April 2016) on the Northern Hemisphere, oceans were 0.85�C or 1.53�F warmer than the 20th century average.

The image below illustrates that temperatures look set to be high in Siberia for the coming week. The panel on the right shows anomalies at the top end of the scale in Eastern Siberia on June 5, 2016, while the panel on the right shows a forecast for June 12, 2016.

These high air temperatures are causing feedbacks that are in turn further speeding up warming in the Arctic.

Warmer Rivers

Temperatures as high as 28.9�C or 83.9�F were recorded over the Mackenzie River close to the Arctic Ocean on June 13, 2016, at location marked by the green circle.

Below is a satellite image of the Mackenzie River delta on June 11, 2016

The image below shows that temperatures as high as 36.6�C or 97.8�F were forecast for June 13, 2016, over the Yenisei River in Siberia that ends in the Arctic Ocean.

Wildfires

Earlier this month, temperatures in Eastern Siberia were as high as 29.5�C (85�F). This was on June 5, 2016, at a location close to the coast of the Arctic Ocean (green circle).

High air temperatures come with increased risk of wildfires, as illustrated by the image below showing carbon monoxide levels as high as 2944 ppb on June 4, 2016 (at green circle).

The satellite image below zooms into the area with these high carbon monoxide readings, showing wildfires on Kamchatka Peninsula on June 3, 2016.

Albedo Loss

The image on the right shows that, this year, April snow cover on the Northern Hemisphere was the lowest on record. The added trend points at a total absence of snow by the year 2036.

Professor Peter Wadhams, head of the Polar Ocean Physics Group at Cambridge University, says: �My prediction remains that the Arctic ice may well disappear, that is, have an area of less than one million square kilometres for September of this year.�

Warming due to Arctic snow and ice loss may well exceed 2 W per square meter, i.e. it could more than double the net warming now caused by all emissions by people of the world, Peter Wadhams calculated in 2012.

Seafloor Methane

Peter Wadhams further co-authored a study that calculated that methane release from the seafloor of the Arctic Ocean could yield 0.6�C warming of the planet in 5 years (see video interview of Thom Hartmann with Peter Wadhams below).

Combined Impact Of Multiple Feebacks

In conclusion, high air temperatures in the Arctic are very worrying, as they can trigger a number of important feedbacks, i.e. the ones discussed above and further feedbacks such as:

• Changes to Jet Streams. As the Arctic warms more rapidly than the rest of Earth, changes are occurring to the jet streams. As a result, winds can increasingly bring hot air far to the north, resulting in further loss of the Arctic snow and ice cover, in turn further warming up the Arctic.
• Warmer Rivers. High air temperatures cause warming of the water of rivers that end up in the Arctic Ocean, thus resulting in additional sea ice decline and warming of the Arctic Ocean all the way down to the seabed.
• Wildfires. High air temperatures set the scene for wildfires that emit not only greenhouse gases such as carbon dioxide and methane, but also pollutants such as carbon monoxide that depletes hydroxyl that could otherwise break down methane, and black carbon that, when settling on ice, causes it to absorb more sunlight (see under albedo loss), besides being a climate forcer when in the atmosphere.
• Soil destabilization. Heatwaves and droughts destabilize the soil. Soil that was previously known as permafrost, was until now held together by ice. As the ice melts, organic material in the soil starts decomposing, resulting in emissions of methane and carbon dioxide, while the soil becomes increasingly vulnerable to wildfires.
• Buffer Loss. Arctic snow and ice cover acts as a buffer, absorbing heat that in the absence of this buffer will have to be absorbed by the Arctic Ocean, as discussed in earlier posts such as this one. 
• Albedo Loss. Arctic snow and ice cover make that sunlight is reflected back into space. In the absence of this cover, the Arctic will have to absorb more heat.
• Seafloor Methane. As sediments at the seafloor of the Arctic Ocean warm, hydrates contained in these sediments could be destabilized and release huge quantities of methane.

How much warmer could it be within one decade?

The two feedbacks mentioned by Peter Wadham (albedo and seafloor methane) are are depicted in the image below.

for further discussion, see the feedbacks page

The combined global temperature rise over the next decade due to these two feedbacks (albedo and seafloor methane) alone may be 0.4�C or 0.72�F for a low-rise scenario and may be 2.7�C or 4.9�F for a high-rise scenario.

Additionally, as temperatures rise, further feedbacks will kick in more strongly, further accelerating the rise in temperature, as also discussed in earlier posts such as this one.

When also including further feedbacks, warming could exceed 10�C (18�F) within one decade, assuming that no geoengineering will take place within a decade, as discussed in earlier posts such as this one.

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

Further Confirmation Of Arctic Sea Ice Dramatic Fall

Since early April, 2016, there have been problems with the sensor on the F-17 satellite that provided the data for many Arctic sea ice images. On April 12, NSIDC issued a notice that it had suspended the provision of sea ice updates. On May 6, NSIDC announced that it had completed the shift to another satellite. The red dotted line in the image below shows data from the F-18 satellite from April 1 to May 15, 2016.

The JAXA site also provides sea ice extent images, obtaining data from a Japanese satellite. They show that Arctic sea ice extent on May 15, 2016 was 11,262,361 square km, 1.11 million square km less than it was on May 15, 2012.

The Cryosphere Today is still using data from the F17 satellite, showing some weird spikes. Albert Kallio has taken a recent image and removed faulty spikes, resulting in the image below showing sea ice area up to May 3, 2016.

[ yellow line is 2016, red line is 2015 ]

Importantly, above image confirms that Arctic sea ice in 2016 has indeed been very low, if not at its lowest for the time of the year. Especially since April 2016, sea ice has fallen far below anything we've seen in earlier years. Below, Albert elaborates on comparing data.

by Albert Kallio? REPAIRED USA (F-17) SATELLITE DATA SHOWS RECORD SMALL SEA ICE AREA IN MAY 2016 AGREEING JAPANESE (JAXA) DATA A corrected Special Sensor Microwave Imager and Sounder (SSMIS) data set on the Defense Meteorological Satellite Program (DMSP) F-17 satellite that provides passive microwave brightness temperatures (and derived Arctic and Antarctic sea ice products) has been corrected here for the system instrumentation error. This agrees with the Japanese JAXA curve, and has been accomplished by removal of the uncharacteristic upward 'ice growth' spikes by linear intrapolation of the corrupt data points. This reinforces the JAXA data that shows the Northern Hemisphere sea ice area is seasonally at new record low which has continued in May 2016. Smoothened F-17 curve agrees with the Japanese JAXA satellite curve. The reconciliation of the two has been accomplished by removal of the uncharacteristic upward spikes by linear intrapolation of the corrupt days' data points which incorrectly showed immense sea ice area growth in the middle of spring melt season. This reinforces the JAXA data that shows the sea ice area is seasonally at record lows. Therefore, media who are citing recent F-17 satellite sea ice area figures are intentionally distorting the facts with their claims of the Northern Hemisphere having a record sea ice area for this time of season - whereas in reality - the exact opposite has been happening.

Arctic sea ice is in a bad shape and looks set to deteriorate even further, for a number of reasons.

The year 2016 is an El Ni�o year, as illustrated by the 51.1�C (124.1 �F) forecast for May 22, 2016, over the Indus Valley in Pakistan (see image right).

Insolation during the months June and July is higher in the Arctic than anywhere else on Earth. Greenhouse gases are at record high levels: CO2 was 408.2 ppm on May 12, 2016, and methane levels are high and rising, especially over the Arctic.

Ocean heat is also very high and rising. The image below shows that 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 situation is further illustrated by the image below, using the NOAA data with a trendline added that points at a rise of 3�C (5.4�F) before the year 2040.

Chances are that Arctic sea ice will be largely gone by September 2016. As the ice declines, ever more sunlight gets absorbed by the Arctic Ocean. This is one out of numerous feedbacks that are hitting the Arctic. The danger is that, as these feedbacks start to kick in more, heat will reach the seafloor of the Arctic Ocean and trigger methane to be released in huge quantities from the Arctic Ocean seabed.

Recently, an abrupt methane release from the Arctic Ocean seafloor did enter the atmosphere over the East Siberian Sea, showing up with levels as high as 2578 ppb (at 586 mb on May 15, 2016, pm, see image below). Such abrupt releases are indications that methane hydrates are destabilizing and are warnings that climate catastrophe is waiting to happen.

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

Wildfire Danger Increasing

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 Bulgajewski?).

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.
