Polar Push & Bounce Back -Trends at the Extremes NEW ZT

**NEW ZETATALK**

This blog is about the Arctic,Antarctica and Extreme Northern/Southern Hemispheres.  Are New Trends happening at the Poles? Weather Patterns, Charts, Images and Unusual Anomalies may be telling us something!

According to the Zetas,  the Wobble Effect has now combined with a new Polar Push!!

Sea ice extent and area have both plummeted to record lows for this time of year in both the Arctic and Antarctic. Such dramatic losses rarely occur at the same time, which means that the global total of sea ice coverage is phenomenally low for this time of year. The weirdness extends to midlatitudes: North America as well as the Arctic have been bathed in unusual mildness over the last several weeks, while Eurasia deals with a vast zone of above-average snowfall and below-average temperatures.

It is clear from the charts that the Earth wobble has increased. First, despite Siberia being on the same latitude with Eastern Canada and Europe, there are vast temperature differences. The globe around the Arctic seems to be divided in half in this way at the current time. Just months ago, in July,
http://www.zetatalk.com/ning/23jy2016.htm
we stated that the hot and cold regions in the Northern Hemisphere were divided into four parts, due to the Polar Push and Bounce Back, and the lean to the Left and Right. Now the increased wobble has created a duality, not the quadrant arrangement of the Figure 8 that had been present since 2004.  

The Polar Push wherein the N Pole of Earth is shoved away from the approaching N Pole of Nibiru continues to create cold temperatures in Siberia, where the magnetic N Pole of Earth currently resides. This has also warmed Antarctica, which is getting more sunlight.  The Bounce Back is more fierce, so that Europe and eastern N America are also getting more sunlight, and thus the melting Arctic. What is missing is the temperature anomalies due to the tilt to the Left and Right. They have been lost in the more aggressive back and forth motion of the Polar Push and Bounce Back.

Prior ZT: http://www.zetatalk.com/ning/23jy2016.htm
The weather maps continue to document the daily Earth wobble, showing abnormal heat over the N American southwest and up into Alaska, and abnormal heat through Europe. Both these regions come under more equatorial sun due to the wobble, due to the lean to the left and then to the right. This is distinctly balanced by cold spots in between. Canada’s eastern provinces and the region above Hudson Bay receive less sunlight due this tilt to one side and then the other. Russia’s Far East and the Siberian region above China of course are pushed into the cold by the daily Polar Push, when the N Pole of Nibiru shoves the Earth magnetic N Pole away.

Ecliptic Rise

http://www.zetatalk.com/index/earthtil.htm

Planet X approaches from the south, and the Pole Shift occurs because the S. Pole is pulled north with the N. Pole of Planet X during the passage. This stress is already evident in that many have noted that the Sun is too far south, rising too far to the south, for the time of year. Possible explanations for this are that the S. Pole has been pulled toward Planet X, creating a different tilt, but the constellations seem to be in their proper place. An alternate explanation is that the Earth's plane of the Ecliptic has changed, rising up, putting the Northern Hemisphere into a different slant, and placing the S. Pole more in line with the N. Pole of Planet X, an alignment Magnets Prefer.    

Natives to the Arctic,  the Inuit years ago already noticed many changes:

Uqalurait: the Snow is Speaking
November 23, 2009
http://www.isuma.tv/hi/en/inuit-knowledge-and-climate-change/uqalur...

An Igloolik elder, describes that uqalurait are changing because the earth itself has "tilted" and has thrown off the consistent wind patterns of the past. The earth tilting on its axis is another re-occuring observation that we are hearing from Inuit, which they know because of how the sun, moon and stars have changed in the sky. Indeed, elders simultaneously know the complexities of the cosmos, land, wind and sky.

Both Poles are affected!

The Zetas describe the Final Days of the Wobble:

http://www.zetatalk.com/index/zeta582.htm

During the last weeks, the Earth changes from being in an end-to-end alignment with Planet X to being in a side-by-side alignment. It is during the end-to-end alignment, when Planet X is pointing its N Pole directly at the Earth, that the lean to the left and 3 days of darkness occur. But as Planet X continues in its retrograde orbit, its N Pole is no longer coming from the right, but is located to the left of the Earth, and the Earth adjusts by slinging its N Pole to the right. Thus, during the 6 days of sunrise west, the Earth still has its N Pole tipped away from the Sun and the approaching Planet X, but rather than a lean to the left, it has a lean to the right.
 
It is at this point that the Earth switches from being in an end-to-end alignment to being in a side-by-side alignment with Planet X. When Planet X is just at the Ecliptic, it stands upright in alignment with the Sun. As it switches from pointing its N Pole at Earth the Earth follows suit.

NEW ZETATALK SEPT 30, 2017 **

http://zetatalk.com/ning/30sp2017.htm

With a stronger Polar Push the bounce back would likewise be more extreme, and the bounce back occurs when the Sun is over the Atlantic.  As the wobble continued to get worse, the Figure 8 corrective lean to the right and left also got more extreme. This sets the stage for the current 2017 hurricane season.

(Modified Earth images are from Google Earth)

Sunlight on Earth reflection based on image in the Planet X Related Captures Blog

The Figure 8 of the wobble creates a churning in the Atlantic:

1.) First land on either side of the Atlantic is pushed under water during the Polar Push,

2.) Then the N American Continent is slung to the East

3.) Then to the West as the day dawns and

4.) Then the bounce back pulls this land back up to the North. 

The wobble, in short, is churning the North Atlantic in a circular motion. Where this fits with the Coriolis effect, where the winds and water curl up from the Equator in a circular motion, moving clockwise in the Northern Hemisphere, the lean to the left does a direct clash, pushing the storm back in a path toward the US coastline.

This is the current Wobble pattern, but the Wobble is subject to change:

5.) A lean into Opposition has occurred, the N Pole leaning toward the Sun. **NEW LEAN**

6.) And a temporary Lean to the Left could occur,

7.) as well as a temporary Day of Darkness for the Northern Hemisphere.

This is not a static situation. (this will occur more than once, in other words).

"There is now less sea ice globally than at any other time since satellite records began in 1978."

'Daunting' Antarctic sea ice plummet could be tipping point

http://www.newshub.co.nz/home/world/2017/11/daunting-antarctic-sea-...

A dramatic drop in the amount of sea ice around Antarctica has scientists wondering if the continent has hit a tipping point. 

There has been a record 30 percent decrease in the total amount of sea ice, and this summer it's disappearing from the Ross Sea at a rate not seen in more than 30 years. 

The rapidly changing conditions are having a major impact on this year's scientific research at Scott Base, with scientists describing the changes as "unusual", "unprecedented" and "daunting".

One of the affected scientists is Antarctic oceanographer Dr Natalie Robinson, who studies sea ice and what lies beneath it. 

"We had about 200km of sea ice to play with last year, but this year we're down to about 25-30km, so it's certainly a very different ball game," she told Newshub.

The team's plan to drill holes through the sea ice has proved impossible this season, with some of their sites now just open water.

It's also affected their camping plans. The team usually bring eight modified shipping containers onto the ice to live and work from for several weeks, but Scott Base checked the ice and it was deemed too thin or weak for heavy vehicles to travel on.

The Antarctic sea ice growth in winter and melt in summer is the biggest annual change on the planet. Dr Robinson describes it as the heartbeat or pulse of Earth, and it affects everybody because it drives global weather.

"It basically doubles the size of Antarctica each year and where that sea ice sits determines where the storms go, and when and where they might hit New Zealand," she said. 

But the big changes occurring in Antarctica impact not only weather, but the health of the world's oceans too, delivering oxygen and nutrients.

During November the sea ice edge is usually around 100km further north of where it is this year. For it to have broken out this early is a significant change and it's causing alarms bells to ring.

"This is my 30th trip into the Southern Ocean and Antarctica," climate scientist Professor Gary Wilson told Newshub.

"Of all the visits I've made down here, we haven't seen the sea ice break out as much as it has this early."

Photo credit: Newshub.

This graph shows the normal range of sea ice in November since 1978. In 2016, there was a sudden and dramatic drop.

This year looks to be following suit.

"We're seeing the ice shelves break up around the peninsula, we're seeing sea ice extent change," Prof Wilson said.

"It dropped rapidly last year and we're seeing now early break-up of the sea ice. Many of these things coming together certainly don't bode well."

The sea ice is not only melting ahead of schedule, there's a lot less of it to begin with. Last year there was 30 percent less ice - a drop of around 1 million square kilometres.

Climate scientists believe Antarctica may have hit a tipping point.

"This could be the moment that Antarctica is catching up with the Arctic," Prof Wilson said.

"Geologically we know that's the case that both poles warm equally, but it hasn't been the case yet with the Antarctic. But maybe this is the moment."

There is now less sea ice globally than at any other time since satellite records began in 1978. Last year, when it reached a record low, was also the hottest year on record.

"The impacts that we're having on the planet, it wouldn't surprise me if we are going to some sort of step change in how the Antarctic sea ice system operates," Dr Robinson said.

"We're really in a critical position I think... We're actually in a race because we know changes are coming, and it's just whether we're ahead of the changes to understand them and predict them better."

Prof Wilson said the abrupt change is "exciting" but troubling.

"In one sense it's exciting we're starting to see signs, in another sense it's daunting because when ice melts it tends to melt rapidly," he said.

The scientists and staff at Scott Base have been forced to adapt to the changes in sea ice this season. They can't traverse as far north on it and it needs to be regularly checked for safety when the large vehicles are driving over it.

At least one expedition has had to be cancelled, while cracks have made some regular routes impassable for vehicles carrying scientific equipment.

Climate scientists will be watching closely over the next few years to establish whether this is a one-off event, or the moment Antarctica began to succumb to a rapidly warming planet.

Update: Satellites measuring Earth’s melting ice sheets go dark

http://www.sciencemag.org/news/2017/09/satellites-measuring-earth-s...

Artist’s conception of the GRACE spacecraft orbiting Earth.

Update, 27 October, 11:25 a.m.: NASA announced today that it has ended GRACE's science operations earlier than expected, after determining that its remaining battery capacity would not be sufficient for one last run that was previously planned to last from October into early November. Its early demise leaves what could be close to a half-year gap in its records before its successor mission, GRACE Follow-On, launches early next year.

Here is our earlier story from 15 September:

A sentinel of Earth’s climate is going dark. After running for a decade beyond its planned life, the Gravity Recovery and Climate Experiment (GRACE) is nearly out of fuel and will soon make its final science run, NASA announced late yesterday. The tandem of satellites—called GRACE-1 and GRACE-2—measure minute shifts in Earth’s gravity to chart flows of mass across the planet, such as the unexpectedly rapid melt of polar ice sheets and the drawdown of underground water reservoirs called aquifers.

Scientists had hoped GRACE would operate until its successor, the $550 million GRACE Follow-on (GRACE-FO) mission, reached orbit. But troubles securing a ride to space have delayed GRACE-FO’s launch until early 2018. Meanwhile, the battery in GRACE-2 used to store solar power has been deteriorating rapidly, forcing the satellite to burn through fuel. Engineers turned off an accelerometer last year to keep it running, but the satellite’s data have continued to degrade.

On 4 September, scientists lost contact with GRACE-2 after another of its battery cells stopped operating. Four days of feverish work followed, with scientists steeling themselves for the mission’s end. But finally, engineers bypassed the satellite’s flight software, successfully rebooting it. NASA has now put GRACE-2 on standby until mid-October, when it will run until early November in full sun on its final planned science collection.

However small, a gap between the missions will make it more challenging to stitch their records together into a seamless whole, says Eric Rignot, a glaciologist at NASA’s Jet Propulsion Lab in Pasadena, California. There are alternative ways to calculate some of the measures GRACE provides, so stopgaps are possible. For example, changes in the mass of the ice sheets can be estimated by using other satellite data to compare discharges of peripheral ice to snowfall accumulations. But there is no comparable method to monitor changes in the mass of glaciers or ice caps, let alone the measures of Earth’s groundwater and soil moisture that hydrologists derive from the satellites. “It would be an impossible task to fill the gap,” Rignot says.

A dynamic duo

A joint U.S.-German effort, GRACE has provided an unprecedented view of the planet’s water and ice since its launch in 2002. The experiment relies on measuring changes in the tug of gravity as the two satellites orbit the Earth. Flying 220 kilometers apart, the GRACE satellites constantly monitor their distance from each other with microwave pulses, down to microns. When the satellites approach a more massive feature, such as an ice sheet, the enhanced gravity of that region tugs a little bit more on the first satellite—briefly widening the distance between the pair—before the second satellite catches up. The changes in distance can be translated into mass.

This data revolutionized entire disciplines, such as hydrology, allowing scientists to document the loss of groundwater due to human exploitation. GRACE showed that the melting polar ice sheets are contributing more to sea level rise than the demise of mountain glaciers. Greenland, it found, is losing 280 gigatons of ice a year on average, while Antarctica is shedding 120 gigatons—rates that both seem to be accelerating. GRACE also inspired a similar mission, NASA’s Gravity Recovery and Interior Laboratory, which probed the moon’s interior.

There’s much that can still be done with GRACE’s archival data, says Isabella Velicogna, a geophysicist at the University of California, Irvine. For example, Velicogna and her colleagues recently used GRACE data to observe for the first time a strange, c...: Melting ice sheets in Greenland and Antarctica are pouring water into the oceans and adding to sea level rise. But the lost ice also means lost gravity—and so sea levels in the immediate vicinity of the ice sheets actually drop, while ocean levels half a world away are goosed. The dynamic, called sea level fingerprints, had wide acceptance in the field, but GRACE provided the first direct confirmation that it was happening.

Although the data gap is unfortunate, it was never a sure bet that GRACE would hold out, Velicogna says. And GRACE-FO, essentially a replication of the first mission, will provide finer mass resolutions by measuring the distance between the two satellites not just with microwaves, but with an experimental laser ranging in.... It’s the same technology that could one day help a planned satellite constellation capture gravitational waves.

Warm waters melting Antarctic ice shelves may have appeared for the first time in over 7,000 years

https://theconversation.com/warm-waters-melting-antarctic-ice-shelv...

The vast expanse of the Antarctic is a region of the world particularly vulnerable to climate change, where ice loss has the potential to significantly increase sea levels.

Now, for possibly the first time in 7,000 years, a phenomenon known as “upwelling” (the upward flow of warmer ocean water to the surface), is thought to have caused recent ice shelf collapse around the continent – and the glacial thinning associated with it.

Ice shelves floating on water are the oceanic extension of land glaciers and ice sheets, and the primary region for ice loss. As these shelves break apart, the flow of continental ice held up behind them accelerates.

The ocean surrounding Antarctica is extremely cold, but water over 300m deep, Circumpolar Deep Water (CDW), is about 3⁰C above the melting point of ice. Normally, the very cold water above keeps this away from ice shelves. But in some areas, CDW is spilling onto the shallow Antarctic continental shelf, causing the ice to thin.

Ice shelf thinning has accelerated in recent decades, but the picture is not the same everywhere. While the east of the Antarctic has shown modest gains in ice thickness, the west has outstripped this with significant ice loss – up to 18% in vulnerable areas like the Amundsen and Bellingshausen Seas.

The pattern of ice loss and other observations indicate that warmer water upwelling beneath these ice shelves is driving it. But what has caused this upwelling? Is it related to human activity? And how concerned should we be?

Two teams led by scientists from the British Antarctic Survey, both of which I have been working with, set out to tackle these precise questions by focusing on two vulnerable areas. One site is in Pine Island Bay, in the Amundsen Sea, and the other is in Marguerite Bay, in the Bellingshausen Sea.

The aims of the studies are similar – to monitor the extent of upwelling warm water onto the continental shelf over the past 10,000 years, in order to understand when this last occurred and what the impact was.

This involves collecting and sampling “cores” of sediment up to 10m long from the sea bed at a range of depths up to 900m. Obtaining suitable cores is particularly challenging in these remote locations, where glacial dynamics often disturb the sediment.

Core evidence

Much of the evidence for past oceanography comes from tiny shells of amoeboid organisms called foraminifera. A huge variety of species colonise habitats on the sea floor and make up much of the sediment collected. There can be hundreds of shells in just one gram of sediment.

 Electron microscope images of planktonic foraminifera N. pachyderma from Pine Island Bay. Scale bar: 100µm equals 0.1mm. Nature Publishing Group

Forams are extremely valuable, as their shells are made of calcium carbonate precipitated from the ocean water in which they lived. Examining these shells allows us to reconstruct the chemistry of ocean water.

There were two geochemical tracers used for warm CDW in Pine Island Bay – the proportion of carbon isotopes, and the magnesium to calcium ratio controlled by water temperature. Both of these showed CDW was last on the inner shelf over 7,500 years ago.

In Marguerite Bay, shells of another plankton group called diatoms were also analysed. These indicate past productivity and sea surface temperatures. They showed that CDW was persistently on the shelf here over 7,000 years ago, and more sporadically since then.

Tellingly, the enhanced upwelling of warm CDW in both locations negatively impacted the local extent of ice.

Winds of change

Both studies suggest that the cause of the CDW upwelling before 7,000 years ago was a more southerly position of the southern hemisphere westerly winds (SHWW). These winds are thought to drive circulation of the warmer deep water. A recent shift in the position of the SHWW towards the poles could be the cause of greater CDW upwelling in Pine Island Bay since the 1940s.

Data llustrating the apparent link between winds and ocean around western Antarctica. The migration of the southern hemisphere westerly winds (SHWW) coincide with upwelling of Circumpolar Deep Water (CDW) in the Amundsen Sea.

This coincidence of timing with the onset of industrialisation shows it is possible that human made greenhouse gasses, thought to cause atmospheric warming, are having an impact on the position of the winds, the increase in warm water reaching the surface, and ultimately the melting of more ice in the Antarctic.

Irrespective of the causes of past changes in SHWW positions, the link between winds and ocean upwelling is cause for concern, as future projected global warming may shift SHWW belts and promote further upwelling and melting. More research is now needed to fully understand the link between CDW and past climate, and to estimate the strength of upwelling since the 1940s compared to upwelling before 7,000 years ago. But the emerging picture is one of the potentially increased vulnerability of West Antarctic ice sheets, and possible future sea level rise.

Giant, mysterious hole was formed in Antarctica

PHOTOGRAPH COURTESY OF MODIS-AQUA VIA NASA WORLDVIEW; SEA ICE CONTOURS FROM AMSR2 ASI VIA UNIVERSITY OF BREMEN. Source of image: news.nationalgeographic.com

18 October, 2017. "A rare phenomenon, this type of open water space was first observed on the ice continent in the 1970s and is referred to by the Russian word polynya.

Sometimes stretching to thousands of square mile, the holes are generally thought to be caused by the deep water in the Southern Ocean being warmer and saltier than the surface water. Therefore, when warmer currents are brought upwards by currents, blankets of ice are melted despite continually low temperatures.

What makes this hole particularly remarkable, however, is that it has occurred "deep in the ice pack", as atmospheric physicist Kent Moore explained to Motherboard. Considering its position, scientists have concluded that it must have been formed by other processes that are not yet clear.

As Moore explains, a polynya was found in the area four decades years ago but only just reappeared last year when it stayed around for a few weeks before disappearing once more. As he says: "This is now the second year in a row it's opened after 40 years of not being there. We're still trying to figure out what's going on."

Breaking news from Pine Island Glacier, which lost 267km2 of icebergs today, after the internal crack resulted in a large calving event 1/n

The Antarctic has again lost a giant iceberg. This time it is an iceberg that has detached itself from the Pine Island glacier and is nearly the size of the New York City borough of Manhattan.

A gigantic iceberg with an area of ​​about 115 square kilometers has broken away from Antarctica, CBC News reported quoting the statement of the National Ice Center in the United States.

This iceberg is the third in the last four years to detach from the Pine Island glacier. In 2013 the glacier lost an iceberg with an area of ​​652 square kilometers and in 2015 another 582 square kilometers.

"It's not the size of the iceberg that matters. This is the frequency, "said Ian Howat, a glaciologist at Ohio State University, quoted by CBS News.

The water that contains the iceberg, is three times that of Lake Garda, and is equivalent to the average water consumed in the world in five years. As early as the iceberg stayed close to the ice platform from which it was born, from September 16, it began to move, separating for the first time from the Larsen C platform of about 18 kilometers.

Pen Hadow Gives Up- Blocked By Sea Ice!

 https://notalotofpeopleknowthat.wordpress.com/2017/08/31/pen-hadow-...

Pen Hadow’s attempt to sail to the North Pole has been rather embarrassingly brought to an abrupt halt by sea ice!

The furthest North they got was 80 degrees 10 minutes, and after being moored to an ice floe for a day, the decision was made to turn tail and head south.

The Arctic Mission website tries to put the best spin on it:

Arctic Mission’s furthest North was 80 degrees 10 minutes North, 148 degrees 51 minutes West, reached at 22:04:12 (Alaskan Time, GMT-9hours) on 29 August 2017 by yachts, Bagheera and Snow Dragon II.

Arctic Mission moored its yachts to an ice floe on 29 August to conduct one of its 24-hour marine science surveys, while drifting with the sea ice. The strategy for any future northward progress had been to monitor the sea surface currents, sea ice, and weather conditions (both observed from the yachts and through satellites imagery downloaded onto our computers), and decide how to proceed as we approached the end of the 24-hour survey.

A meeting of the four skippers was held led by Erik de Jong, with Pen Hadow present, and it was agreed further northward progress would increase considerably the risks to the expedition, with very limited scientific reward. The decision to head south, back to an area of less concentrated sea ice in the vicinity of 79 degrees 30 minutes North, was made at 18.30 (Alaskan time)...."

Delingpole: Ship of Fools IV: Another Green Arctic Expedition Scuppered by Ice

http://www.breitbart.com/big-government/2017/09/01/delingpole-ship-...

This is not the first time Hadow has been denied the “bittersweet achievement” of pinning Arctic melt on “climate change.” In 2009 – with encouragement from the Prince of Wales – Hadow led the Catlin Arctic Survey expedition which had to be cancelled less than half way into its 800 mile trek because the equipment broke in the freezing temperatures.

His latest failure comes a year after yet another sailing expedition – this one called The Polar Ocean Challenge, led by veteran explorer David Hempleman-Adams – was also frustrated by unexpectedly large quantities of ice.

That was Ship of Fools II.

Ship of Fools I was, of course, the glorious December 2013 expedition to Antarctica – led by an Australian alarmist called Chris Turney, one of the correspondents in the Climategate scandal  – which had to be called off after becoming stuck in ice which Turney insisted could not have been predicted.

Then earlier this summer, we learned of Ship of Fools III – a Canadian research expedition which had to be cancelled because, you guessed it, of “unprecedented” summer sea ice.

Trillion-tonne iceberg finally snaps off West Antarctic ice shelf, scientists confirm

JULY 12, 2017

http://www.news.com.au/technology/environment/climate-change/trilli...

A TRILLION-tonne iceberg more than four times the size of our ACT has finally broken off the West Antarctic ice shelf, scientists have confirmed.

The Antarctic Peninsula's rift in the Larsen C ice shelf from NASA's IceBridge mission Digital Mapping System. Picture: AFP

A TRILLION-tonne iceberg, one of the largest ever recorded, has snapped off the West Antarctic ice shelf, scientists have confirmed.
Researches have been monitoring the steadily growing crack in the Larsen C Ice Shelf for years. Swansea University finally announced on Wednesday that the rift had completed its path through the ice, causing a 5,800-square kilometre section of the shelf to snap off.

The massive ice cube is twice the size of the Australian Capital Territory, four times the size of London and twice the size of Luxembourg. It is about 350 metres thick.
“The iceberg weighs more than a trillion tonnes

he research team said. It will likely be named A68.

With the calving, the Larsen C ice shelf lost more than 12 per cent of its total surface area.
Icebergs calving from Antarctica are a regular occurrence. But given its enormous size, the latest berg will be closely watched as it travels, for any potential risk to shipping traffic.
The calving may have heightened the risk of the remaining ice shelf disintegrating, the Swansea team said.

Rain Over Arctic Ocean

http://arctic-news.blogspot.co.nz/2017/07/rain-over-arctic-ocean.html

It's raining over the Arctic Ocean and the rain is devastating the sea ice.

On July 6, 2017, cyclonic winds lined up to create a 'perfect storm'. As a result, an Atmospheric River of moisture was driven through Bering Strait into the Arctic Ocean, as shown on the images below.

On July 6, 2017, 1500 UTC, winds in Bering Strait were as high as 58 km/h (36 mph) at surface level (green circle on above image left), and as high as 82 km/h (51 mph) at 850 mb (green circle on above image right).



On July 6, 2017, surface temperatures of the air in Bering Strait were as high as 8.1°C (46.5°F) (green circle on image right).

Another indication of the strength of the wind driven through Bering Strait is wave height. On July 6, 2017, waves were as high as 3.35 m or 11 ft in the Bering Strait, at the location marked by the green circle on the image on the right.

The relatively warm and moist air driven through Bering Strait by strong winds is causing rain to fall over the sea ice of the Arctic Ocean, as shown on the video and images further below.

On July 7, 2017, high air temperatures were recorded over land and over the water.

The image below shows temperatures recorded at two locations over the Mackenzie River, one of 32.6°C or 90.8°F at the mouth of the Mackenzie River and another one of 34.7°C or 94.5°F further inland. Warm water from rivers can substantially warm up the sea surface and thus melt the sea ice.

Temperature of the surface of the water was 10°C or 50.1°F where the water was pushed into the Bering Strait, while temperatures as high as 46.9°C or 116.3°F were recorded over California.

The combined impact of high temperatures, strong winds, high waves and warm river water, rain water and melt water looks set to further devastate what sea ice is left in the Arctic Ocean.
Rain can be particularly devastating. The very force at which rain strikes can fracture the sea ice where it's weak, while pools of rainwater and meltwater will form at places where the sea ice is stronger. Where fractures appear in the sea ice, warm water can reach further parts of the ice and widen the cracks.

The video below shows rain over the Arctic Ocean. The video was created with cci-reorganizer.org forecasts from July 3, 2017, 18:00 UTC to July 17, 2017, 00:00 UTC.

Arctic sea ice is in a terrible shape. Sea ice volume is at a record low, as indicated by the Wipneus image below showing volume anomalies from 2002.

The image below, by Torstein Viddal, shows how low the 2017 year-to-date average sea ice volume is.
An additional danger is wildfires. Due to high temperatures, wildfires have broken out near the Mackenzie River, as illustrated by the satellite image below.
