Oldspeak:” While the media gives wide coverage to the heatwaves that have been hitting populous countries such as India, Pakistan, the U.S., Spain and France recently, less attention is given to heatwaves hitting the Arctic.” -Sam Carana
“Mere months following reports of record heat recorded in Antarctica near the South fucking Pole, we see this. Seems as though corporate media’s sensationally reported disaster porn is focused only the mid-latitudes, while the region where the stakes are highest and the heatwave is most life-threateningly unusual, is ignored. By way of reference, it was 80 degrees in New York on July 2nd when this insane temperature was recorded near the North fucking Pole!!! This syncs up with current movement of the ever slowing and destabilized jet stream where as you can see in Sam’s illustrations its cooler than normal around that area of the U.S. east coast, as arctic air creeps further south. It’s only broken 90 once or twice so far this summer in New York, following a brutally cold and snowy winter/fall. This is a dire situation, it affects all life on earth, and it is not being reported. I imagine business will continue as usual and it won’t be reported until it’s impossible to ignore.

Written By Sam Carana @ Arctic News:
The image below illustrates the intensity of the heatwave over western Europe, with temperatures forecast to keep hitting the top end of the scale for days to come.
Global warming is strengthening heatwaves. The Arctic is warming faster than the rest of the world, so the temperature difference between the North Pole and the Equator is getting smaller. It is this temperature difference that powers the jet stream. The result is that the speed at which the jet stream circumnavigates the globe is falling. Furthermore, the path of the jet stream is changing, sometimes extending far to the north, then deeper to the south, just like a river will meander more where the land is flatter.
Above image illustrates that these changes to the jet stream make that warm air from the south can more easily move up north, to higher latitudes, while cold air from the Arctic can more easily move down to lower latitudes, in both cases further decreasing the temperature difference between the North Pole and the Equator, which makes these changes to the jet stream a self-reinforcing feedback loop that is rapidly making the situation worse.
While such developments have been documented for years, e.g. see this feedbacks page, the media rarely inform people about them. And while the media do cover the suffering caused by the heatwaves that have been hitting populous countries such as India, Pakistan, the U.S., Spain and France recently, less attention is given to heatwaves hitting the Arctic.
High temperatures close to the Arctic Ocean 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 a location well inside the Arctic Circle where temperatures as high as 37.1°C (98.78°F) were recorded on July 2, 2015. The top panel shows temperatures, while the bottom panel also shows the depth of the Arctic Ocean and the location of the Gakkel Ridge, in between the northern tip of Greenland and the Laptev Sea.
As the image below shows, the jet stream is forecast to move up high into the Arctic north of Siberia over the next few days. The image shows the jet stream as at July 8, 2015.
The image below shows a forecast of temperature anomalies for July 7, 2015.
The four images below illustrate how the heatwave is forecast to develop over the next few days (hat tip to Mark Richardson).

| Rain close to the North Pole (forecast July 7, 2015) |
The image on the right, also created with a Climate Reanalyzer image, shows rain over the Arctic, over the EastSiberian Sea and over an area close to the North Pole.
Rain over sea ice will create melt ponds with associated loss in albedo (reflectivity), making that light that was previously reflected back into space by the sea ice will instead be absorbed by the water, further speeding up the demise of the sea ice.
The picture below was taken July 2, 2015, by WebCam#1, mounted on a satellite-reporting buoy. The camera provides a wide-angle 120° horizontal field of view and was installed in April 2015, about 1.5 m above the ice surface, at a location some 25 miles from the North Pole. The buoy has meanwhile drifted some distance away from the North Pole, see map at this page.

| WebCam#1 showing water on July 2, 2015 |
The presence of water can indicate that the sea ice has completely disappeared in the respective area, which could in turn be caused by sea ice melting and/or bubbling up of methane, so it’s important to keep monitoring this. More likely though, the water is probably surface water on top of the ice, caused by melting and/or rain. Anyway, water reflects less sunlight back into space than sea ice, so the result will be that more sunlight is instead absorbed by the water and/or the sea ice.
With temperatures as high as the 37.1°C (98.78°F) recorded on July 2, 2015 (image further above), huge melting can be expected where there still is sea ice in the waters off the coast of Siberia, while the waters where the sea ice has already gone will warm up rapidly.
Note that the waters off the coast of Siberia are less than 50 m (164 ft) deep, so warming can quickly extend all the way down to the seabed, that can contain enormous amounts of methane in the form of free gas and hydrates.
The situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan.
