Climate graphic of the week: Arctic warming four times faster than rest of the planet
Scientists have warned that the Arctic is warming four times faster than the rest of the planet, and at a higher rate than previously thought, according to new research, while the Antarctic ice is also diminishing.
The research on the Arctic, published in the academic journal Communications Earth and Environment, studies data from as far back as 1979 when Arctic temperature estimates from satellites became available.
Scientists have for a long time known that the Arctic is heating faster than the rest of the planet, but have not agreed on a rate. The warming effect, along with long-term declines in sea ice levels, are considered two major indicators of climate change.
The most recent landmark Intergovernmental Panel on Climate Change signed off by 234 scientists from more than 60 countries estimated that the Arctic was only warming around twice as fast as the rest of the planet. Global temperatures have risen at least 1.1C since pre-industrial times.
High sea temperatures are also causing diminishing sea ice in Antarctica, as temperatures rise in the Bellinghausen, Amundell and Weddell seas.
The new research comes as record-breaking heat was experienced across parts of the globe last month (July 2022), which ranked one of the three hottest on record.
Climate change transforming Arctic into ‘dramatically different state’
This year’s Arctic Report Card is the 16th annual volume of original, peer-reviewed environmental observations and analysis that documents rapid and dramatic shifts in weather, climate, terrestrial and oceanic conditions in the circumpolar region. Compiled by 111 scientists from 12 nations.
“The Arctic Report Card continues to show how the impacts of human-caused climate change are propelling the Arctic region into a dramatically different state than it was in just a few decades ago,” said NOAA Administrator Rick Spinrad, Ph.D. “The trends are alarming and undeniable. We face a decisive moment. We must take action to confront the climate crisis.”
Some of this year’s Arctic significant findings include:
- The October-December 2020 period was the warmest Arctic autumn on record dating back to 1900. The average surface air temperature over the Arctic this past year (October 2020-September 2021) was the 7th warmest on record. The Arctic continues to warm more than twice as fast as the rest of the globe.
- The snow-free period across the Eurasian Arctic during summer 2020 was the longest since at least 1990. June 2021 snow cover in Arctic North America was below the long-term average for the 15th consecutive year. June snow cover in Arctic Europe has been below average 14 of the last 15 years.
- Following decades of relative stability, the Greenland ice sheet has now lost mass almost every year since 1998, with record ice loss in 2012 and 2019. In August, rainfall was observed at the Greenland ice sheet’s 10,500-foot summit for the first time ever.
- The volume of post-winter sea ice in the Arctic Ocean in April 2021 was the lowest since records began in 2010. The amount of older, biologically important multiyear sea ice at the end of summer 2021 was the second-lowest since records began in 1985.
- The total extent of sea ice in September 2021 was the 12th lowest on record. All 15 of the lowest minimum extents have occurred in the last 15 years. The substantial decline in Arctic ice extent since 1979 is one of the most iconic indicators of climate change.
- The loss of sea ice has enabled shipping and other commercial and industrial activities to push deeper into the Arctic, in all seasons, resulting in more garbage and debris collecting along the shore and more noise in the ocean, which can interfere with the ability of marine mammals to communicate.
- Some of the fastest rates of ocean acidification around the world have been observed in the Arctic Ocean. Two recent studies indicate a high occurrence of severe dissolution of shells in natural populations of sea snails, an important forage species, in the Bering Sea and Amundsen Gulf.
“The Arctic story is a human story,” said Twila Moon, an Arctic scientist with the National Snow and Ice Data Center, and one of three editors of the 2021 Arctic Report Card. “We all have a role to play in creating the best possible outcomes for the region, its residents and all the citizens of the globe who depend on the Arctic as a critical component of our Earth system.”
The Arctic has a new record high temperature, according to the U.N.

Climate Changes at This National Park Stunned Me
By Jon Waterman
Mr. Waterman is a former national park ranger and the author of National Geographic’s “Atlas of the National Parks.”
Secluded in the far-flung Gates of the Arctic National Park in northwestern Alaska, the flooded Noatak River pushed our raft downstream into a brisk wind. Caribou trails spider-webbed the hillsides, while cumulus clouds gathered like ripened fruit above a valley so vast that you could feel lost without binoculars and frequent map consultations.
To avoid crashing into the banks, I had to keep sharp eyes on the surging river and hands on the oars. Since extreme rainfall had lifted the river out of its banks (and delayed our floatplane flight in from Bettles, Alaska, for three days), every potential campsite had been sluiced over with silt and left soaking wet.
Thirty-six years had passed since I had last worked as a guide on the Noatak River. This year, instead of simply enjoying a float down memory lane in the wildest country imaginable, I was stunned by how climate change had radically altered the place I once knew.
Drawn to wild places all my life for spiritual renewal, I had chosen the Noatak as the ultimate wilderness trip to share with my 15-year-old son, Alistair, and another family. I had also come to escape the record heat and forest fire smoke in Colorado for what I believed would be a cool interlude in the Far North.
To my surprise, the temperatures approached 90 degrees Fahrenheit for three consecutive days. The bugs were strangely thick. We had come in August hoping the frosts that usually began that month would have killed off the infamous clouds of mosquitoes. But climate change had lengthened the summers and delayed the cold, so we needed head nets and bug dope.
Alistair and I repeatedly cooled off by swimming in the river, an activity I had never considered during dozens of trips to the chilly North. But the last six years have seen some of the warmest weather on record in Alaska.
Since my first trip down those headwaters in 1982, temperatures in the Arctic have risen several degrees Fahrenheit. Back then, we dressed for winter in the first week of August. Soon afterward, though, scientists began to warn that the Arctic was warming at twice the global average. In the decades since, this part of Alaska has been subjected to abnormal heat waves and wildfires.
When a storm blew in on Aug. 5, temperatures dropped into the 50s and rain fell again as we floated out of Gates of the Arctic and into the Noatak National Preserve. The legislated wilderness shared between these two parks stretches more than 13 million acres, which makes it the nation’s greatest untrammeled landscape sheltering the largest unaltered river system. But the region’s protected status seems scant consolation given the cascade of climate change anomalies.
One of them is the thawing of the permafrost, the frozen ground that covers nearly a quarter of the Northern Hemisphere. I explained to Alistair that global warming has taken the permafrost out of the proverbial freezer. Eons of crustal earth movement, glacial scraping and soil deposition stirred and pushed ancient masses of plant life underground and flash-froze everything into permafrost before it could rot. More carbon is contained within this frozen ground than humankind has released since the Industrial Revolution began.
Now, it’s as if frozen spinach was left out on the kitchen counter. The permafrost has begun to decompose and emit carbon and methane into the atmosphere — adding to the human-generated greenhouse gases that are already causing planetary warming. The effects of the thawing were plain to see.
My feet mostly stayed dry on my tundra hikes in the 1980s; this time, we repeatedly soaked our boots walking across tundra drenched with weeping permafrost. The mountains above were bereft of snow. Year-round snow cover in Gates of the Arctic has all but disappeared. Of the 34 square miles of white snowfields seen in 1985, just four square miles remained by 2017, according to one study. On the Noatak, we had to steer our rafts wide around thawing riverbanks as stones fell and silt rained down into the river. Our drinking water filter repeatedly plugged up from the dislodged sediment.
The consequences pile on, in little ways and big ones.
A recent study of the area’s smaller rivers and streams found that the thawing permafrost is cooling the waters, which biologists say could hurt salmon reproduction. This raises long-term concerns for remote downstream communities that depend on salmon for sustenance. Flying in, we had also seen watery craters known as thermokarsts punched into the verdant tundra. They’re caused by the melting of surface ice on top of thawing permafrost. Lakes have flooded out of their basins, too, as the surrounding tundra walls have melted away like butter.
Woody shrubs are also moving north over the tundra and low grassy areas as the climate becomes more hospitable for them. The shrubs in turn transfer more of the sun’s heat through the snow and ground and into the permafrost. In 1982 I had discovered a den occupied by a family of wolves on a high bank of the Noatak amid knee-high dwarf birch and grass; today most of the river banks are festooned with head-high willows.
Since plants harbor a large part of the energy supply and habitat for wildlife, this “greening of the Arctic” is changing the entire ecosystem. Drawn by these woody shrubs, moose, beavers and snowshoe hares are now moving north and causing further alterations. Shrubs also reduce lichen cover, which is an essential food for over 250,000 caribou that pass through the region, some traveling up to 2,700 miles in their migration to and from their calving grounds.
For all of the changes we saw, we still reveled in a wilderness so remote and untraveled that we saw only one other person on our 90-mile, six-day trip from Pingo Lake to Kavachurak Lake. We caught grayling in the river and sautéed it for dinner while sheltering from the hot sun under a propped-up raft. We gorged on wild blueberries. For an hour in a bug-quelling wind atop a hillside we watched a grizzly and its cubs, unaware of our presence, cavort and splash across the tundra.
All this as caribou shepherded their young down from the summer calving grounds as they have done for thousands of years. We didn’t see many, but we knew they were out there, somewhere, cantering in synchronized, thousandfold troupes, inches apart yet never jostling one another, their leg tendons a veritable orchestra of clicking castanets, their hooves clattering on stones. These tawny creatures drift along their ancient trails like tendrils of smoke through one of our last great wild places.
These parks are an essential treasure of our democracy, conceived by Congress and presidents past as monuments for posterity. Now they offer a look at the future of climate change, which has slammed into the Arctic in ways not yet seen in the temperate world.
Unable to sleep one night, I slipped past my dozing son and emerged from our tent into the surreal soft light of a midnight sunset as a rainbow arced like an heaven-sent bridge over the river. In times like this I could only think about both of my sons and how they and all of our future generations will be left to face the uncertainties of an overheated planet.

At the International Climate Summit in Glasgow
by Seth Borenstein @ the COP-26 /
The Arctic is warming three times faster than the rest of the planet and is on such a knife’s edge of survival that the U.N. climate negotiations underway in Scotland this week could make the difference between ice and water at the top of the world in the same way that a couple of tenths of a degree matter around the freezing mark, scientists say.
The fate of the Arctic looms large during the climate talks in Glasgow — the farthest north the negotiations have taken place — because what happens in the Arctic doesn’t stay in the Arctic. Scientists believe the warming there is already contributing to weather calamities elsewhere around the world.
“If we end up in a seasonally sea ice-free Arctic in the summertime, that’s something human civilization has never known,” said former NASA chief scientist Waleed Abdalati, who runs the University of Colorado’s environment program. “That’s like taking a sledgehammer to the climate system.”
What’s happening in the Arctic is a runaway effect.
What Happens in the North Doesn't Stay in the North
It's All Connected
Ben See (@ClimateBen) Tweeted:
Hardly anybody on Earth knows that the Arctic is warming 3 to 4 times faster than the rest of the planet as its sea ice is destroyed during the abrupt climate change event of 20th/21st century capitalism. Radical action is required now in 2021. Nobody will be immune to this.
It's All Connected
You often hear @MichaelEMann say the models underestimate the connection... a connection between climate change and a more amp’d - wavy jet... you can see how when we have a natural wavy jet pattern, which is very established this spring/summer, climate change impacts enhance it, by having more energy in the system (heat and moisture) magnifying extremes.
Jennifer Francis of Woods Hole Research Institute drew the connection back in 2015. Viewing an increase in jet stream waviness, she and fellow authors concluded, “These results suggest that as the Arctic continues to warm faster than elsewhere in response to rising greenhouse-gas concentrations, the frequency of extreme weather events caused by persistent jet-stream patterns will increase...”
Some models which emphasize Arctic heating show a tripling by the end of the century. But if we can keep global heating under 2°C/3.6°F, we can likely avert those increases.
This is why we need dramatic reductions in burning coal, oil and natural gas beginning immediately, as well as in deforestation, another significant source of climate pollution. The emergence of radical impacts demands radical action. Business as usual is done. If we want to leave a world with which our children can cope, when the capacity of humanity and nature to adapt is stressed beyond the breaking point, we need to rise up as people and demand change now.

(CNN) Russia launched its space satellite Arktika-M on Sunday on a mission to monitor the climate and environment in the Arctic amid a push by the Kremlin to expand the country's activities in the region.
The Arctic has warmed more than twice as fast as the global average over the last three decades and Moscow is seeking to develop the energy-rich region, investing in the Northern Sea Route for shipping across its long northern flank as ice melts.
The satellite successfully reached its intended orbit after being launched from Kazakhstan's Baikonur cosmodrome by a Soyuz rocket, Dmitry Rogozin, the head of Russia's Roscosmos space agency, said in a post on Twitter.
Russia plans to send up a second satellite in 2023 and, combined, the two will offer round-the-clock, all-weather monitoring of the Arctic Ocean and the surface of the Earth, Roscosmos said.

World's ice melting faster than ever
From Antarctica to the Arctic, the world’s ice is melting faster than ever, according to a new global satellite survey that calculated the amount of ice lost from a generation of rising temperatures.
Between 1994 and 2017, the Earth lost 28 trillion metric tons of ice, the survey showed. That is an amount roughly equivalent to a sheet of ice 100 meters thick covering the state of Michigan or the entire U.K.
“It’s such a huge amount it’s hard to imagine it,” said Thomas Slater, a research fellow at the U.K.’s University of Leeds Centre for Polar Observation and Modelling and the lead author of a paper describing the new research.
From the polar caps to the glaciers of Europe, Asia and South America, global warming is melting the planet’s ice faster than ever and speeding the inundation of the world’s coastlines.
New research shows the annual melt rate grew from 0.8 trillion tons in the 1990s to 1.3 trillion tons by 2017, and has accelerated most in the places with the most ice—the Greenland and Antarctic ice shelves and sheets.
Those massive systems of land and sea-based ice are melting as fast as the worst-case climate scenarios in major global climate reports, said Thomas Slater, a co-author of the new study in The Cryosphere that measured the meltdown from 1994 to 2017, which covers a timespan when every decade was warmer than the previous one and also includes the 20 warmest years on record.

Polar-ward climate zones shift and consequent tipping points
by Andrew Glikson
The concept of a global climate tipping point/s implies a confluence of climate change processes in several parts of the world where regional climate changes can combine as a runaway shifts to a new climate state. Conversely the shift of climate zones can constitute the underlying factor that triggers extreme weather events which culminate in tipping points. These shifts include the expansion of the tropics, tropical cyclones, mid-latitude storms and weakening of boundaries of the polar vortex, allowing breach of air masses of contrasting temperatures through the jet stream polar boundary, with ensuing snow storms and heatwaves.

Warming shrinks Arctic Ocean ice to 2nd lowest on record
by Seth Borenstein, Science Writer / Associated Press
A Farewell to Arctic Ice
Ice Sheet Melt Worst Case Scenario
Greenland's ice sheet lost an annual record of 532 billion tons of ice, with 223 billion tons of ice lost during the month of July alone.
To put that in comparison, between 2003 and 2016 the ice sheet lost about 255 billion tons of ice on average -- per year.
"We have documented another record loss year for Greenland," said Ingo Sasgen, a glaciologist at the Alfred Wegener Institute for Polar and Marine Research and co-author of the study.
"What this shows is that the ice sheet is not only out of balance but it's increasingly likely to produce more and more extreme loss years."
The report follows another study published last week that found Greenland's ice sheet has melted to a point of no return, and is retreating in rapid bursts, leading to a sudden and unpredictable rise in sea levels.

New study warns: We have underestimated pace at which the Arctic is melting
Temperatures in the Arctic Ocean between Canada, Russia and Europe are warming faster than researchers' climate models have been able to predict.
Over the past 40 years, temperatures have risen by one degree every decade, and even more so over the Barents Sea and around Norway's Svalbard archipelago, where they have increased by 1.5 degrees per decade throughout the period.
This is the conclusion of a new study published in Nature Climate Change.
"Our analyses of Arctic Ocean conditions demonstrate that we have been clearly underestimating the rate of temperature increases in the atmosphere nearest to the sea level, which has ultimately caused sea ice to disappear faster than we had anticipated," explains Jens Hesselbjerg Christensen, a professor at the University of Copenhagen's Niels Bohr Institutet (NBI) and one of the study's researchers.
'Another Ice Sheet Disintegrates'
Scientists from the National Snow and Ice Data Centre (NSIDC) at the University of Colorado Boulder initially predicted the disappearance of the St. Patrick Bay ice caps would take place over five years, but it's actually only taken three.
The frozen sheets, probably in place for several centuries, measured more than 10 square kilometres (3.86 square miles) combined at the end of the 1950s, and have now shrunk down to nothing. It's a sign of the climate change that's gaining momentum all around the world, and showing no signs of stopping.

The new research paper, written by 15 international experts, predicts the effects of a 3.6°F (2°C) average global temperature rise – a milestone anticipated in the Paris Agreement.

The Arctic has been warming twice as fast as the rest of the planet, with higher temperatures pushing sea ice into a loop of melting and thinning. Its extent is lower today than in the ‘80s and ‘90s in “every area, every month and every season”, according to a recent IPCC report, which points out the plunging sea ice levels of September are probably unseen in at least 1,000 years. The same report points out that the Arctic’s sea ice melt season has grown as ice melts earlier and waters freeze later in the year. “We'll have winter sea ice for a long time to come, but unless actions are quickly taken, the summer sea ice might be essentially gone only a few decades from now,” says Dr. Mark Serreze, director of the National Snow and Ice Data Center (NSIDC).

Oil, Gas, Minerals & Mining in a Melting Arctic
A heatwave in Greenland is producing record highs across the ice sheet, including at East Grip, the second highest monitoring station. “If you start melting at the top of the ice sheet, we are going to lose [the] Greenland ice sheet long-term."
At the summit of the Greenland ice cap the temperature rarely rises above zero degrees centigrade — the elevation is 3,200m and the ice below is more than a mile thick.
But last Friday (Aug 2, 2019), as the sun beat down, a small weather station laden with sensors captured something highly unusual: the temperature crept past zero and up to 3.6C — the highest since records began three decades ago. As temperatures rose across the massive ice sheet, which blankets an area five times the size of Germany, around 60 per cent of the surface started to melt, one of the largest ever recorded.
Scientists know of only three prior occasions in the past 800 years when there has been melting at the very top of the ice cap, which is kept chilled by the large volume of ice beneath. But this seems to be getting more frequent — it is now the second time this decade it has happened.

Key indicators of Arctic climate change: 1971–2017
Anchorage Daily News / Where's the Ice?
Sea ice is again at a historic low in the Bering Sea.
At the time of year when ice usually reaches its maximum, there’s open water in a vast area stretching from Bristol Bay to the Bering Strait, said Rick Thoman, a climate specialist with Alaska Center for Climate Assessment and Policy at the University of Alaska Fairbanks.
“You could take your sailboat and sail from Dillingham all the way to Little Diomede and never see much more than an ice cube,” he said.
In the middle of Bering Strait, the ice went out on Thursday, leaving nothing but water...
March and early April are typically when sea ice in the Bering Sea reaches its maximum extent, and when communities that live along the coast travel on the ice for subsistence hunting and fishing.
The unprecedented lack of ice in the Bering Sea follows another record-breaking winter. Last spring, in 2018, the extent of ice in the Bering Sea only reached half of its previous lowest size, which was recorded in 2001. Thoman called the lack of ice “stunning” at the time.
This spring, the situation is even more extreme. While there’s more ice on the Russian side of the Bering Sea, there’s virtually none on the Alaska side.
Melting Arctic ice lets world's biggest shipping firm complete first voyage through previously impenetrable Northeast Passage
- Maersk sent a new ship across the polar sea for the first time
- The route has historically been difficult to traverse because of thick sea ice
- Global warming has melted much of the route, opening it up to trade ships
The Northern Sea Route could be a shorter route for journeys from East Asia to Europe than the Northwest Passage over Canada because it will likely be free of ice sooner due to climate change.
The container vessel, Venta Maersk, traveled from Vladivostok to St Petersburg over the northern top of Russia.
Experts say the new passage reduces the most commonly used East Asia-Europe route via the Suez Canal from 13,000 miles (21,000 kilometres) to 8,000 miles (12,800 kilometres), cutting transit time by 10-15 days.
Typically vessels taking this icy route have required an ice-breaker escort, but rising global temperatures are making the passage easier to traverse.
The Northern Sea Route is becoming appealing to the shipping industry, especially to the oil and gas sector, as it is much shorter than the Suez Canal.
The reduction of ice in the Arctic and design of new ice-breaking commercial vessels make the transportation of abundant Arctic natural energy resources commercially viable.

Via The oldest and thickest sea ice in the Arctic has started to break up, opening waters north of Greenland that are normally frozen, even in summer.
This phenomenon – which has never been recorded before – has occurred twice this year due to warm winds and a climate-change driven heatwave in the northern hemisphere.
One meteorologist described the loss of ice as “scary”. Others said it could force scientists to revise their theories about which part of the Arctic will withstand warming the longest.
The sea off the north coast of Greenland is normally so frozen that it was referred to, until recently, as “the last ice area” because it was assumed that this would be the final northern holdout against the melting effects of a hotter planet...

In an interview with Yale Environment 360, polar scientist Mark Serreze talks about the rapid changes he has witnessed over more than three decades of working in the Arctic and the future stability of the region if temperatures continue to climb.
- We’re going to have an Arctic that, except for winter, you look at it from satellite and it’s going to be a blue ocean. It will have lost its ice. Not just its sea ice, but a lot of the permafrost will be thawed, the snow cover season will be much shorter. The thing is, when you’re thinking about the Arctic, the Arctic’s soul is its ice. When you lose that ice, the Arctic loses its soul.

- Withdrawal from joint venture brokered by Tillerson for now marks end of energy giant’s hopes of drilling in Arctic ocean oil fields
The Texas oil giant said in a regulatory filing late Wednesday that it would walk away from the joint venture with state-controlled PAO Rosneft to seek oil in the ice-choked waters of the Kara Sea, a hard-fought deal signed in 2012 by the company’s former chief executive, Rex Tillerson, now U.S. secretary of state.
Mr. Tillerson had touted the agreement as a breakthrough giving Exxon access to one of the world’s great unexplored oil and gas basins. The company reportedly spent about $700 million to drill the first well, likely making it the most expensive ever. It struck oil, according to Rosneft...
Exxon declined to comment on the reasons for its decision. The company said it would formally begin to withdraw from the Rosneft joint ventures this year, taking a $200 million loss after taxes.
Rosneft said in a statement carried by Russian news agencies that it would support the return of Exxon to the projects in the future if it were legally possible.

How's the Weather?
Arctic temperatures are soaring
by Joe Romm
It was the warmest December on record in the Arctic, and 2018 has already set a string of records for lowest Arctic sea ice.
Unfortunately for America and the rest of the planet, the best science makes clear that what happens in the Arctic doesn’t stay in the Arctic. “We long ago anticipated that warming would be greatest in the Arctic owing to the vicious cycle of melting ice and warming oceans,” climate scientist Mike Mann told ThinkProgress via email.
“But what we didn’t anticipate is the way that changing wind patterns could accelerate that process — and along with it, a host of nasty associated surprises.”
Surprises include “including slowing down of ocean currents, and whacky weather patterns in North America associated with weather extremes like droughts, wildfires, floods, and superstorms.”
And those are in addition to the “nasty” associated impacts that scientists have long predicted would result from Arctic warming, such as faster melting of the land-based Greenland ice sheet, which in turn drives the speed up in sea level rise that scientists reported last week (Feb. 12, 2018)....
- John Abraham, professor of thermal sciences: “The temperatures in the Arctic are off the chart. This matters for the rest of us because this is the time of year when the Arctic ice should be growing. But it isn’t growing like it should. So, this summer, there will be less ice and more open waters that will lead to more warming. We've started a feedback loop that we cannot stop.”

Head of the US House Committee on Science: Climate Change is "Beneficial"
Lamar Smith's New Line: It's time to Celebrate
WASHINGTON / HuffPost / July 24, 2017 — Rep. Lamar Smith (R-Texas) — who has spent his career cozying up to fossil fuel interests, dismissing the threat of climate change and harassing federal climate scientists — is now arguing that pumping the atmosphere full of carbon dioxide is “beneficial” to global trade, crop production and the lushness of the planet.
Rather than buying into “hysteria,” Americans should be celebrating the plus sides of a changing climate, Smith argues in an op-ed published July 24th in The Daily Signal, a news website published by the conservative Heritage Foundation.

Why Care About Black Carbon?
Rex Tillerson speaks of 'how the Trump administration will approach the issue of climate change'
Tillerson’s appearance in Alaska at the Arctic Council Ministerial Meeting comes two days after the White House said Trump would postpone a decision over whether to pull out of the landmark Paris climate accord until after he meets world leaders at the Group of Seven summit later this month.
“We are currently reviewing several important policies, including how the Trump administration will approach the issue of climate change,” Tillerson said Thursday during his remarks to the Arctic Council, which also includes Finland, Denmark, Iceland, Norway, and Sweden. “We’re going to work to make the right decision for the United States.”
Tillerson called for vigilance in protecting the Arctic’s “fragile environment.” The U.S. will continue to be an active member of the council," he said. “The Arctic region has been facing unprecedented change and challenges.”
Initially (in their joint "Fairbanks Declaration" statement that accompanied the Council's meeting,) the U.S. objected to references to climate change, renewable energy and United Nations sustainability goals in an early draft of the joint statement, said Rene Soderman, senior adviser for Arctic cooperation at the Ministry of Foreign Affairs of Finland. The council reworked the wording and convinced the U.S. to accept the changes.
“We were able to push the U.S. back as much as possible,” Soderman said.

Snow, Water, Ice and Permafrost in the Arctic: Summary for Policy-makers
The Arctic Transformed
The Arctic is warming faster than any other region on Earth. Over the past 50 years, the Arctic’s temperature has risen by more than twice the global average.
The Arctic Council is the leading intergovernmental forum promoting cooperation, coordination, and interaction among the Arctic States, Arctic indigenous peoples, and other Arctic inhabitants on common Arctic issues, in particular on issues of environmental protection and sustainable development in the Arctic. Established in 1996, the Arctic Council is composed of eight Member States (Canada, the Kingdom of Denmark, Finland, Iceland, Norway, the Russian Federation, Sweden, and the United States). It also includes six organizations representing Arctic indigenous peoples.

On a tour on the Franz Josef Land archipelago, a sprawling collection of islands where the Russian military has recently built a new runway and worked to open a permanent base, Putin emphasised on Wednesday (March 29) the need to protect Russia's economic and security interests in the Arctic.
"Natural resources, which are of paramount importance for the Russian economy, are concentrated in this region," Putin said in remarks carried by Russian news agencies.
Putin said current estimates put the value of the Arctic's mineral riches at $30 trillion.
NASA's Earth Science News Team / Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.

February 11, 2017 via CS Monitor — Records are shattering left and right across the Arctic, much like the ever-dwindling sea ice that once covered the entire Arctic Ocean.
First, the facts. January sea ice area has never been so small. In November, the coverage fell short of average by an area the size of the eastern half of the United States. Northeast Greenland had its warmest February day ever (by almost four degrees). The current heat wave brought temperatures near the North Pole to 50 degrees above average...
“We’re still trying to figure out what is happening here,” Mark Serreze, a senior research scientist with the Colorado-based Snow and Ice Data Center that compiles and reports the history of Arctic ice conditions.

Ex-Chief of ExxonMobil Testifies Before US Congress
- President-elect Donald Trump's nominee for Secretary of State, Rex Tillerson, said he believes the risks of climate change "could be serious enough that action should be taken,” but he did not elaborate on what that action should be.
Tillerson testified that he formed his views “over about 20 years as an engineer and a scientist, understanding the evolution of the science.” Ultimately, he said, he concluded that increasing greenhouse-gas concentrations in the atmosphere are having an effect on the earth’s climate. But he added, “Our ability to predict that effect is very limited,” and precisely what actions nations should take “seems to be the largest area of debate existing in the public discourse.”

First Cruise Ship Crossing the Ice-Free Arctic Passage
- http://www.ktva.com/shows/frontiers/episode-74-crystal-serenitys-historic-voyage-951/ Arrival (September 16, 2016) in New York City ...
The beginning of cruise ships plying the formerly isolated, ice-bound region... prompting calls for a clamp-down to prevent Titanic-style accidents and the pollution of fragile eco-systems resulting from accidents -- and new gas/oil production.
Arctic nations begin to consider limiting the size of vessels and banning the use of heavy fuel oil in the region after first luxury cruise ship, Crystal Serenity, sailed through the Arctic from Alaska, across Canada's newly navigable Northwest Passage, to New York in the summer of 2016.
Next up, commercial shipping traffic, container ships ...
Shipping industry report:
Sea-ice is in a committed, long-term decline as the polar north warms.
This year looks on course to be the second lowest in the satellite record. Researchers do not see this trend being reversed anytime soon.
“If we experience a 2-degree increase in global temperatures, we will get close to an Arctic that is effectively ice-free for part of the year; that’s less than a million sq km of ice cover,” said Reading University's Dr. Ed Hawkins.
“So, even if future emissions are consistent with the Paris agreement, it will of course mean shipping routes will be more open. Not every year, but more regularly than they are now.”
“Open water vessels won’t be hugging the Russian coast quite so much, and ice-strengthened ships will be going right over the pole,” he told BBC News.
The incentives are clear: if vessels can transit the Arctic, they will shave many days off their journey times between the Pacific and North Atlantic ports, and save fuel.
In addition, by plotting a more central course, they can avoid the fees they would otherwise be charged for going through Siberian waters.
The team has been looking at how the opportunities might evolve in the decades ahead.
The group used five prominent climate computer models and essentially trained them to better reflect the distribution of Arctic sea-ice as seen in current observations.
They then ran those models forward through the century under different emissions scenarios, to gauge where and how frequently shipping routes would become navigable.
"The Northwest Passage"
Oil major ExxonMobil (XOM.N) and Russia's Rosneft ROSN.M unveiled an offshore exploration partnership on Wednesday that could invest upward of $500 billion in developing Russia's vast energy reserves in the Arctic and Black Sea.
The deal, between the world's largest listed oil firm and the world's top oil producing nation, was the product of nearly a year of talks and came about despite a history of mutual distrust between Washington and Moscow dating back to the Cold War and recent difficulties for other Western firms in Russia.
"Experts say that this project, in terms of its ambitions, exceeds sending man into outer space or flying to the moon," Russian Deputy Prime Minister Igor Sechin, a key architect of the partnership, told a briefing for analysts in New York.
Under the deal, signed in Moscow on Monday, Exxon and state-controlled Rosneft will seek to develop three fields in the Arctic with recoverable hydrocarbon reserves estimated at 85 billion barrels in oil-equivalent terms.
A final investment decision on the projects in the Kara Sea, in the centre of Russia's north coast, is expected in 2016-17, Rosneft said in a video presentation at the event, which was hosted by Exxon CEO Rex Tillerson and Rosneft President Eduard Khudainatov.
