Heat Wave Forecast For Russia Early June 2015

Following heat waves in Alaska and the north of Canada, the Arctic looks set to be hit by heat waves along the north coast of Russia in early June, 2015. The image below shows temperature anomalies at the top end of the scale for a large area of Russia forecast for June 6, 2015.

Meanwhile, the heat wave in India continues. It killed more than 2,100 people, reports Reuters, adding that the heat wave also killed more than 17 million chickens in May. The number of people killed by the heat wave is now approaching the 2,541 people killed by the 1998 heat wave in India, which is listed as the record number of deaths due to extreme temperatures in India by the Emergency Events Database.

Further records listed by the database are the well over 70,000 people killed by the 2003 heat wave in Europe and 55,736 people killed by the 2010 heat wave in Russia alone.

On above temperature forecast (left image, top right), temperatures over a large area of India will be approaching the top end of the scale, i.e. 50°C or 120°F. While such temperatures are not unusual in India around this time of year, the length of the heat wave is extraordinary. The heat wave that is about to hit Russia comes with even higher temperature anomalies. Even though temperatures in Russia are unlikely to reach the peaks that hit India, the anomalies are at the top end of the scale, i.e. 20°C or 36°F.

Below is a forecast for the jet stream as at June 7, 2015.

The animation below runs the time of the top image (June 6, 2015, 0900 UTC) to the above image (June 7, 2015, 1200 UTC), showing forecasts of the jet stream moving over the Arctic Ocean, with its meandering shape holding warm air that extends from Russia deep into the Arctic Ocean.

Below is another view of the situation.

Jet stream on June 6, 2015, 0900 UTC, i.e. the date and time that corresponds with the top image.

Clicking on this link will bring you to an animated version that also shows the wind direction, highlighting the speed (I clocked winds of up to 148 km/h, or 92 mph) of the jet stream as it moves warm air from Russia into the Arctic Ocean, sped up by cyclonic wind around Svalbard.

This is the 'open doors' feedback at work, i.e. feedback #4 on the feedbacks page, where accelerated warming in the Arctic causes the jet stream to meander more, which allows warm air to enter the Arctic more easily, in a self-reinforcing spiral that further accelerates warming in the Arctic.

The implications of temperatures that are so much higher than they used to be are huge for the Arctic. These high temperatures are heating up the sea ice from above, while rivers further feed warm water into the Arctic Ocean, heating up the sea ice from below.

Furthermore, such high temperatures set the scene for wildfires that can emit huge amounts of pollutants, among which dust and black carbon that, when settling on the sea ice, can cause large albedo falls.

The image below shows Russian rivers that end up in the Arctic Ocean, while the image also shows sea surface temperature anomalies as high as 8.2°C or 14.76°F (at the green circle, near Svalbard).



The big danger is that the combined impact of these feedbacks will accelerate warming in the Arctic to a point where huge amounts of methane will erupt abruptly from the seafloor of the Arctic Ocean.
The image below shows that methane levels as high as 2566 ppb were recorded on May 31, 2015, while high methane levels are visible over the East Siberian Arctic Shelf.

Below is part of a comment on the situation by Albert Kallio:

As the soils warm up the bacteria in them and the insulating capacities of snow themselves tend to lead snow cover melting faster the warmer the soil it rests on becomes. (Thus the falling snow melts very rapidly on British soil surface if compared to Finland or Siberia where the underlying ground is much colder, even if occasionally the summers have similar or even higher temperatures).

The large snow cover over the mid latitude land masses is a strong negative feedback for the heat intake from the sun if the season 2015 is compared with the season 2012, but the massive sea ice and polar air mass out-transportation equally strongly weakens formation of new sea ice around the North Pole (and along the edges of the Arctic Ocean) as the air above the Arctic Ocean remains warm. The pile up of thin coastal ice also increases vertical upturning of sea water and this could have detrimental effects for the frozen seabed that is storing methane clathrates. The sunlight intake of the sea areas where sea ice has already disappeared corresponds largely with the 2012 season.

The inevitable snow melting around the Arctic Ocean will also transport record volumes of warmed melt water from the south to the Arctic Ocean. The available heat in the Arctic may also be later enhanced by the high sea water temperatures that prevail along the eastern and western coasts of North America, as well as El Nino event increasing temporarily air and sea surface temperatures. This leads to more depressions around Japan and Korea from where the warm air, storms and rains migrate towards Alaska and pull cold air away from Arctic over Russia, while pushing warm air through the Baring Strait area and Alaska to the Arctic Ocean region.

Forecasting seasonal out comes is likely to be increasingly difficult to make due to increasing number of variables in the seasonal melting processes and the resulting lack of historic precedents when the oceans and Arctic has been as warm as today. Thus the interplay of the opposing forces makes increasingly chaotic outcomes, in which the overall trend will always be for less ice and snow at the end of the season. Because of these reasons - including many others not explicitly mentioned here - the overall outcome for the blue ocean, or the ice-free Arctic Ocean, will be inevitable.

Whether the loss of sea ice happens this summer, or next, or one after that, the problem isn't going to go away and more needs to be done to geoengineer to save Arctic ice and wildlife dependent on summer sea ice.

John Davies responds:

Albert Kallio is absolutely right in saying that warmer temperatures are leading to a blue ocean event though the problem remains in which year this will happen. Additionally Methane is being released from the bottom of the ocean leading to increased Methane concentrations and all that means for a destabilising global climate. Frustratingly, the higher temperatures and increasing Methane concentrations are not yet quite sufficient for us to persuade the scientific community and the public that Armageddon is on the way. Hence it is not yet possible to be in a position to persuade the world community of the urgent need for Geo-engineering to save the Arctic and Global climate. However we may reach this situation in the near future and that will be the only time when it might be possible to save the global climate and prevent Armageddon.

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

Arctic Methane Skyrocketing

The map below shows observatories in the Arctic.

'Arctic methane skyrocketing' is the title of a video by Paul Beckwith discussing recent rises in methane levels in the Arctic.

Paul's description: "I discuss how ground level flask measurements of methane have been spiking upwards over the last few years. I analyze the implications to the breakdown of climate stability, causing jet stream fracturing and weather regime change. I believe that this behaviour will rapidly worsen as Arctic temperature amplification continues, leading our planet to a much warmer and unrecognizable climate over the next 5 to 10 years."

Below are some NOAA images showing methane levels (surface flasks) recorded at Arctic observatories.

Below is an image showing hourly average in situ measurements at Barrow, Alaska, including one very high reading, from an earlier post.

Arctic Sea Ice in Uncharted Territory

On May 27, 2015, Arctic sea ice extent was merely 11.973 million square kilometers, a record low for the time of the year since satellite started measurements in 1979.

This fall in sea ice extent follows heat waves in Alaska and the north of Canada, as illustrated by the image below.

Temperature in Alaska on the afternoon of May 23, 2015, when a temperature of 91°F (32.78°C) was recorded in Eagle. 

High temperatures extended over the Beaufort Sea and Chukchi Sea. The image below shows the difference in sea surface temperatures between May 13, 2015, and May 23, 2015.

The large amounts of meltwater flowing into Beaufort Sea and the Chukchi Sea is illustrated by the image below, showing the difference in sea surface salinity between May 17, 2015, and May 24, 2015.

Sea ice has retreated dramatically in the Chukchi Sea and the Beaufort Sea, and in Baffin Bay, with high sea surface temperature showing up where rivers flow into the Arctic Ocean and where the Gulf Stream carries warm water from the Atlantic Ocean into the Arctic Ocean.

The size-reduced navy.mil animations below show the fall in sea surface salinity (left) and the fall in sea ice thickness (right) in the Beaufort Sea, from May 3, 2015, to June 2, 2015 (run May 27, 2015).

Sleeping Giant in the Arctic

Huge amounts of carbon are contained in sediments, soils and vegetation in the Arctic. Rising temperatures in the Arctic threaten to cause much of this carbon to be released to the atmosphere.

On May 23, 2015, temperatures in Alaska were as high as 91°F (32.78°C), as illustrated by the image below.

[ image credit: US National Weather Service Alaska ]

High temperatures were reached at the city of Eagle, located on the southern bank of the Yukon River, at an elevation of 853 ft (260 m). High temperatures at such a location will cause meltwater, aggravating the situation well beyond the local area.

River in Siberia. Credit: University of Georgia

Carbon contained in soils will thus become increasingly exposed under the combined impact of rising temperatures and the associated growing amounts of meltwater. The meltwater can additionally cause erosion further downstream, thus making carbon at many locations become more prone to be consumed by microbes and released into the atmosphere in the form of carbon dioxide and methane.

A recent study found that, at a location where the Kolyma river in Siberia carved into the permafrost and exposed the carbon, microbes converted 60% of the carbon into carbon dioxide in two weeks time.

Gary Houser, who recently launched the movie Sleeping Giant in the Arctic, elaborates on the threat of emissions from thawing permafrost:

This immense release would likely feed on itself, raising temperatures that continue melting more and more permafrost in a vicious, frightening, and unstoppable cycle. A tipping point could well be crossed, at which time human intervention is no longer possible. Temperatures across the planet could soar, setting in motion catastrophic levels of drought and food shortage. All life support systems on earth and life forms themselves could be placed under severe stress.

The colossal scale of the danger - and the observation of those factors lining up that could trigger it - demand that humanity exercise the precautionary principle. All political decision-making related to carbon emissions must be based on the understanding that a catastrophic consequence is looming, and the window of time for prevention quickly diminishing.

Arctic Sea Ice At Historic Low

On May 20, 2015, Arctic sea ice extent was only 12.425 million square km, a record low for the time of the year since satellite measurements began in 1979.

As the Arctic Sea Ice is at a historic low, Alaska faces temperatures as high as 31°C (87.8°F), as illustrated by the image below.

How is it possible for temperatures to get so high at locations so close to the North Pole?

Typhoon Dolphin

Dr. Michael Ventrice, Operational Scientist at The Weather Channel Professional Division points at two typhoons, Noul and Dolphin, that recently hit the western Pacific Ocean.

These typhoons do have some impact. Importantly, global warming is increasing the strength of cyclones. In other words, a greater impact of cyclones on the jet stream can be expected as a feedback of global warming.

Furthermore, global warming is directly changing the path followed by the North Polar Jet Stream, from a relatively straight path at a latitude of 60°N to a wildly meandering path that at some places merges with the Subtropical Jet Stream and reaching speeds as high as 267 km/h (166 mph) and that at other places moves high into the Arctic and reaches speeds as high as 170 km/h (106 mph).

On above image, part of the jet stream even moves right across the pole. Such changes to the jet stream constitute one out of numerous feedbacks of global warming, as discussed at the feedbacks page. Decline of the snow cover and sea ice in the Arctic is another such feedback.

As discussed in earlier posts, heat waves at high latitudes cause thawing of frozen soil and melting of glaciers and snow cover, This results in large amounts of water draining into rivers that end up in the Arctic Ocean. At the same time, heat waves also raise the temperature of the water in these rivers. The larger amounts of warmer water result in additional sea ice decline and warming of the Arctic Ocean seabed.

Such heat waves also 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).

Above image shows how much warmer the water in the Arctic Ocean is compared to what it used to be, with high anomalies where rivers flow into the Arctic Ocean and where the Gulf Stream carries warm water from the Atlantic Ocean into the Arctic Ocean.

The situation looks set to get worse, as the frequency and intensity of heat waves in North America and Siberia increases as temperature at high latitudes are rising rapidly. Furthermore, warm water is lining up along the path of the Gulf Stream, with sea surface temperature anomalies as high as 10.3°C (18.54°F) recorded off the coast of North America on May 20, 2015, as illustrated by the image below.

Green circle shows a 10.3°C (18.54°F) sea surface temperature anomaly from daily average (1981-2011)

Meanwhile, a very high methane reading was recorded at Barrow, Alaska (hourly average, in situ measurement), as illustrated by the image below.

The big danger is that the combined impact of these feedbacks will accelerate warming in the Arctic to a point where huge amounts of methane will erupt abruptly from the seafloor of the Arctic Ocean.

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

Mackenzie River Warming

On May 12, 2015, a temperature of 80.1°F (or 26.7°C) was recorded in the north of Canada, at a location just north of latitude 63°N.

High temperatures in such locations are very worrying, for a number of reasons, including:

• They are examples of heatwaves that can increasingly extend far to the north, all the way into the Arctic Ocean, speeding up warming of the Arctic Ocean seabed and threatening to unleash huge methane eruptions.  
• They 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). 
• They 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 seabed. 

The image below shows increased sea surface temperature anomalies in the area of the Beaufort Sea where the Mackenzie River is flowing into the Arctic Ocean.

The image below further illustrates the situation, with sea ice thickness (in m) down to zero where the Mackenzie River flows into the Arctic Ocean.

Things look set to get worse. The forecast for May 16, 2015, shows high temperatures extending all the way to the coast where the Mackenzie River flows into the Arctic Ocean.

Updates follow below: 
Alaska is hit by high temperatures as well. The image below shows temperatures as high as 25.3°C (77.54°F) at a location just north of latitude 66°N in Alaska.

Below a forecast for May 23, 2015, showing temperatures in Alaska and neighboring parts of Canada that are 36°F (20°C) higher than they used to be (1979-2000 baseline).

The image below shows that temperatures as high as 30.2°C (86.36°F) are forecast for Alaska for May 23, 2015, along the path of the Yukon River, at a latitude of ~66 degrees North (65.98°N).

Furthermore, temperatures as high as 24.2°C (75.56°F) are forecast for the coast, close to where the Mackenzie River flows into the Arctic Ocean. Off the coast, over the water of the Arctic Ocean, temperatures as high as 8°C (46.4°F) are forecast, for a location just north of latitude 70°N, while temperatures as high as 15°C (59°F) are forecast for a location over the water of the Arctic Ocean closer to land.

As the image below illustrates, the jet stream is forecast to move across Alaska on May 23, 2015, bringing warm air into the atmosphere over the Arctic Ocean. The image gives the jet stream's speed at three locations, i.e. the jet stream is forecast to reach speeds as high as 262 km/h (162.8 mph, bottom green circle) over the Pacific Ocean, 165 km/h (102.5 mph, middle green circle) south of Alaska, and 172 km/h (106.9 mph, top green circle) over the Arctic Ocean.

Looking at salinity is a way to see the impact of rivers. The animation below, created with Naval Research Laboratory images over the period May 16 to 20, 2015 (run on May 18, 2015), shows salinity levels falling where the Mackenzie River flows into the Arctic Ocean.

Salinity works in several ways. Falling salinity will increase the temperature at which the sea ice melts. However, such an increase can only temporarily hold back melting, as illustrated by the combination image below, comparing sea ice thickness between May 7 and May 18, 2015.

Let's have a look at some of the feedbacks that haven't been discussed much in earlier posts. The potential for rivers to contribute to sea ice decline is depicted in the diagram below (feedback #24), i.e. extreme weather causing warming of rivers that flow into the Arctic Ocean. Furthermore, evaporation rates are higher over fresh water surfaces than over saline water surfaces (feedback #26) and the resulting increase in water vapor and clouds contributes to further warming (feedback #25), while rain falling on the sea ice will also cause its albedo to decline. The latter feedback also closes some loops. in that sea ice retreat results in more open water, in turn resulting in more water vapor and clouds.

Another feedback is that, as more sea ice turns into open water, less infrared radiation will be emitted and sent out into space, since open oceans are less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum (feedback #23). Furthermore, as sea ice declines, the increase in Arctic phytoplankton warms the ocean surface layer through direct biological heating (feedback #22).

For more discussion of these feedbacks, see the feedbacks page. In conclusion, the situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan page.

The Great Unraveling

The great unraveling of how climate catastrophe is unfolding on land and in the oceans, in the atmosphere and the cryosphere, is becoming more and more clear every month.

March 2015 temperatures were the highest for March in the 136-year period of record. NOAA analysis shows that the average temperature across global land and ocean surface temperatures combined for March 2015 was 0.85°C (1.53°F) higher than the 20^th century average of 12.7°C (54.9°F).

Ocean temperature anomalies on the Northern Hemisphere for March 2015 were the highest on record. In many ways, the situation looks set to get worse. For the 12-month period from April to March, data from 1880 contain a trendline that points at a rise of 2 degrees Celsius by the year 2032, as illustrated by the image below.

Click on image to enlarge

The rise in Northern Hemisphere ocean temperatures was especially profound in September and October 2014, when methane started to erupt from the Arctic Ocean seafloor in huge quantities.

The image below shows a polynomial trendline pointing at an October Northern Hemisphere sea surface temperature anomaly rise of 2°C (3.6°F) by 2030, and a rise of more than 5°C (9°F) by 2050, compared to the 20^th century average, from an earlier post.

From: Ocean Temperature Rise continues

The images below give an idea of the current sea surface temperature anomalies around North America.

On April 11, 2015, a sea surface temperature of 22.2°C (71.96°F) was recorded off the North
American coast (green circle bottom), a 12.6°C (22.68°F) anomaly (green circle top).

Ocean heat is carried by the Gulf Stream from the North Atlantic into the Arctic Ocean. The huge amounts of energy entering the oceans translate into higher temperatures of the water and of the air over the water, as well as higher waves and stronger winds.

The image below highlights waves and winds, showing that waves as high as 12.06 m (39.57 ft) were recorded off the coast of North America in the path of the Gulf Stream, while winds with speeds as high as 115 km/h (71.46 mph) were recorded in that area on April 17, 2015.

The combination image below illustrates the threat. A sea surface temperature of 8°C (46.4°F, green circle left) was recorded near Svalbard on April 17, 2015, an anomaly of 6.2°C (11.16°F, green circle right).

Click on image to enlarge

A continued rise of ocean temperatures on the Northern Hemisphere threatens to unleash huge eruptions of methane from the seafloor of the Arctic Ocean, further accelerating the temperature rise in the Arctic and escalating into runaway global warming.

Malcolm Light comments: "The Pacific heating must be caused by the southward spreading Arctic methane global warming veil that is able to penetrate through a giant hole in the hydroxyl and ozone layer over the far east and is moving eastwards."

Current methane levels remain extremely high (see this recent post), on track to break the record mean level of 1839 ppb (parts per billion) reached in September 2014.

Above image shows that the highest mean methane levels ranged from 1815 ppb on March 30, 2015, to 1828 ppb on April 17, 2015. The highest peak level during this period was 2483 ppb, reached on April 15, 2015.

The extremely high methane levels are undoubtedly contributing to the high temperatures reached in March, especially at higher latitudes, on top of the dramatic global rise of greenhouse gases in general, as illustrated by above contribution by Peter Carter.

Above image shows that temperature anomalies over much of the Arctic Ocean were at the top end of the scale on April 17, 2015, i.e. 20°C or 36°F.

The image below gives an idea of the temperature differences on April 17, 215. While temperatures over the Sahara in Africa were as high as 32.1°C (89.78°F), temperatures over Greenland were as low as -41°C (-41.8°F). In between, temperatures of 2.8°C (37.04°) were recorded over the waters near Svalbard and of 6.1°C (42.98°F) closer to the coast of Norway.

Such wide temperature differences highlight the importance of looking at peaks, rather than at averages. The year-to-date maximum sea surface temperature anomaly, up to April 18, 2015, gives an idea of the peak anomalies that can be expected as the hot season approaches on the Northern Hemisphere.



Below are details for March 2015.

Temperature anomalies as high as 10.2°C (or 18.3°F) were recorded for March 2015 on Kolguyev Island in the Barents Sea.

A rise in ocean temperatures on the Northern Hemisphere of 2°C (3.6°F) by October 2030 looks set to go hand in hand with a 6°C (10.8°F) rise in Arctic temperatures by 2030, fueling runaway global warming, as illustrated by the image below, from another earlier post.

Without action, similar temperature rises look set to hit the globe at large a dozen years later, accompanied by huge temperature swings that threaten to cause depletion of supply of food and fresh water, as discussed by Guy McPherson in the video below and illustrated by the image further below.
