Arctic sea ice: is the minimum maximum the new normal?
If you blinked, you might have missed it. The confirmation came this week that the Arctic sea ice reached yet another all-time low this past winter. It came and went, without too much ado.
Maybe the excitement was just past. The maximum extent was actually reached on March 7th, but of course you can only be sure it is really not going to spread any further once it has definitely been retreating for some time with the onset of spring.
I was waiting for the NSIDC confirmation, but not with any doubt in my mind that it would tell us officially the maximum for this season would be a minimum.
The danger is a “so what?” kind of reaction, or resignation, with the feeling that nothing short of some kind of unprecedented experimental geo-engineering could save the Arctic summer sea ice in the coming years, as the world continues to warm.
Lowest on record
The National Snow and Ice Data Center (NSIDC), part of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, and NASA confirmed this week that Arctic sea ice was at a record low maximum extent for the third straight year.
It reached the maximum on March 7, at 14.42 million square kilometers (5.57 milion square miles). Since then, it has started its annual decline with the start of the melt season. Some time in September it will reach its minimum.
This year’s maximum is the lowest in the 38-year satellite record. NSIDC scientists said a very warm autumn and winter had contributed to the record low maximum. Air temperatures were 2.5 degrees Celsius (4.5 degrees Fahrenheit) above average over the Arctic Ocean. Against the background of overall warmth came a series of “extreme winter heat waves over the Arctic Ocean, continuing the pattern also seen in the winter of 2015”, NISDC said in a statement.
The air over the Chukchi Sea northwest of Alaska and the Barents Sea north of Scandinavia was even warmer, averaging around 9 degrees Fahrenheit (five degrees C) above the norm.
NSIDC director Mark Serreze said in his statement: “I have been looking at Arctic weather patterns for 35 years and have never seen anything close to what we’ve experienced these past two winters.”
The winter ice cover was also slightly thinner than that of the past four years, according to data from the European Space Agency’s CryoSat-2 satellite. Data from the University of Washington’s Pan-Arctic Ice Ocean Modeling and Assimiliation System also showed that the ice volume was unusually low for this time of year.
Record summer melt ahead?
“Thin ice and beset by warm weather – not a good way to begin the melt season,”, said NSIDC lead scientist Ted Scambos.
A low maximum does not necessarily mean the minimum to be measured in September will also be a record low, as it depends on summer weather patterns. But Julienne Stroeve from NSIDC and professor of polar observation and modeling at the University College London said “Such thin ice going into the melt season sets us up for the possibility of record low sea ice conditions this September”.
“While the Arctic maximum is not as important as the seasonal minimum, the long-term decline is a clear indicator of climate change”, said Walt Meier, a scientist at the NASA Goddard Space Flight Center Cryospheric Sciences Laboratory and an affiliate scientist at NSIDC. Iceblog readers might wonder if that is stating the obvious, but given the attitudes of the US administration, you can’t take anything for granted.
The September sea ice measurements began to attract attention in 2005, when the ice extent first shrank to a record low over the period of satellite observations. It broke the record again in 2007 and in 2012. There used to be little interest in the maximum extent of the Arctic sea ice at the end of winter. I can remember reading with concern and writing a piece about the maximum extent also reaching a record low in 2015.
“Arctic sea ice extents have followed a steady downward trajectory since the start of the 21st century – at the same time global temperatures have reached new record highs. Betides setting multiple record low summertime minimum extents, Arctic sea ice began to exhibit a pattern of poor winter recovery starting around 2004.”
Living on thin ice
I remember an expedition to Alaska in 2008, when locals at Barrow told me about their personal experiences of the sea ice becoming thinner and less dependable. Some years later I heard similar reports from people in Greenland, who were selling their sled dogs and buying boats in preparation for changing from ice to open water fishing. The data backs them up.
Yereth Rosen, writing for Alaska Dispatch News, draws attention to the problems of continuing to collect that data. She quotes NSIDC’s Serreze:
“Just how well the center will be able to track sea ice in the future remains unclear. No new satellite is expected to be in place until 2020, and there are concerns about potential interruptions in the record that goes back to 1979… We’re at a situation where the remaining passive microwave instruments up there are kind of elderly. If we have satellite failures, we could lose that eye in the sky”.
Now there is a worrying thought.
Against the background of budget cuts proposed by the Trump administration, that – to put it mildly – does not regard tracking climate change as a high priority – scientists are understandably worried about the future of scientific research on climate and environment related issues.
Method in the madness?
Without reliable continuous satellite data, it would be much harder to track how climate change is affecting the polar regions, the ocean and our planet in general. This may well be the intention of climate-change deniers behind the scenes. But climate change itself will not go away – and the impacts will be increasingly evident.
Tim Ellis, writing for Alaska Public media, quotes Serreze as saying the polar ice cap will not last long if the region continues to warm at this rate.
“We are on course sometime in the next few decades, maybe even earlier, to have summers in the Arctic where, you go up there at the end of August, say, and there’s no ice at all.”
“The view from space in the fall of around 2040” , he went on – assuming we still have satellites to take the pictures – “will be of a blue Arctic Ocean, aside from some scattered icebergs and clusters of pack ice”.
I don’t know about you, but I find that a rather depressing thought.
Implications for the rest of the globe
Andrea Thompson, for Climate Central, writes “even in the context of the decades of greenhouse gas-driven warming, and subsequent ice loss in the Arctic, this winter’s weather stood out.”
She also reminds us of the global impacts of a warming Arctic and decline in sea ice:
“The Arctic was one of the clear global hotspots that helped drive global temperatures to the second- hottest February on record and the third-hottest January, despite the demise of a global heat-boosting El Nino last summer.”
This week the UN’s World Meteorological Organisation (WMO) said 2016 had been the hottest year ever recorded, and that the record-breaking heat had continued into 2017, sending the world into “truly uncharted territory”.
“The dramatic melting of Arctic ice is already driving extreme weather that affects hundreds of millions of people across North America, Europe and Asia, according to emerging research”, Damian Carrington writes in the Guardian.
On March 15th, Carrington published an article entitled “Airpocalypse smog events linked to global warming”, referring to extreme smog occurrences in China.
Optimism – the only way to go?
This week I interviewed German oceanologist and climatologist Mojib Latif. I wanted to find out whether the highly unusual extreme rainfall and flooding happening in Peru could be explained by natural cycles or was likely to be a climate change impact which could reoccur. You can read the interview here or listen to it on my Living Planet show this week online or on soundcloud.
The professor stressed that the scientists are baffled, because it is not really the time for an el Nino, although this seems to be a “coastal el Nino”, driven by exceptionally warm water off the coast. Of course he is reluctant to attribute any single event to climate change. He stated unequivocally, though, that the warming of the ocean worldwide was absolutely inexplicable without anthropogenic CO2 emissions, that this is all in line with climate models and that we should all be preparing for an increasing number of increasingly extreme weather events, as the world warms.
He says the governments of the world (apart perhaps from the new US administration) are in no doubt that climate change is happening and they need to halt it. But they have so far failed in their attempts.
When I asked Professor Latif if he still felt optimistic, he told me we really had no other choice. While critical of the lack of government action, he is convinced the world will realize that renewables are ultimately far superior to fossil fuels and will ultimately prevail. The question is whether that will happen in time. As far as the Arctic summer sea ice is concerned, I have to go with a Scots expression: “A hae ma doots”.

Arctic summer sea ice cover could disappear with 2C temperature rise
The Arctic sea ice may disappear completely in summers this century, even if the world keeps to the Paris Agreement. That is the worrying message of a report published on Monday in the journal Nature Climate Change.
The 2015 Paris Agreement set a goal of limiting the rise in global temperature to well below two degrees Celsius (3.6 Fahrenheit) above pre-industrial times. Ideally, 1.5C (2.7F) was agreed to be the “aspirational” target. James Screen and Daniel Williamson of Exeter University in the UK, wrote, after a statistical review of ice projections, that a two degree Celsius rise would still mean a 39 percent risk that ice would disappear from the Arctic Ocean in summers. If warming is kept to 1.5 degrees Celsius, the ice was virtually certain to survive, they calculated.
Current emissions targets way too low
If you take the old “glass being half-full rather than half-empty” metaphor, you could see that as a positive option to hang on to. However, the scientists estimated that if we continue along current trends, temperatures will rise by three degrees C (5.4 F.). That would give a 73 percent probability that the ice would disappear in summer. To prevent it, governments would have to up their targets and make considerably larger cuts in emissions than presently planned.
The sea ice will reach its maximum winter extent some time soon. So far, the March figures rival 2016 and 2015 as the smallest for the time of year since satellite records began in the late 1970s.
“In less than 40 years, we have almost halved the summer sea ice cover”, Tor Eldevik, a professor at the Bjerknes Centre for Climate Research at the University of Bergen in Norway, told Reuters. Eldevik was not involved in the study.
He predicted that sea ice would vanish in the Arctic Ocean in about another 40 years, on current trends.
Steady melting trend
Scientists define an ice-free Arctic Ocean as one with less than one million square kilometers (386,000 square miles) of ice, because they say some sea ice will linger in bays, for instance off northern Greenland, even after the ocean is ice-free.
Despite fluctuations from year to year, long-term trends in the Arctic clearly show a decline in sea ice. The ten lowest ice extents since 1979 have all occurred since 2007.
According to the latest figures from the NSIDC (March 6), high air temperatures observed over the Barents and Kara Seas for much of this past winter moderated in February. Still, overall, the Arctic remained warmer than average and sea ice extent remained at record low levels.
Arctic sea ice extent for February 2017 averaged 14.28 million square kilometers (5.51 million square miles), the lowest February extent in the 38-year satellite record. This is 40,000 square kilometers (15,400 square miles) below February 2016, the previous lowest extent for the month, and 1.18 million square kilometers (455,600 square miles) below the February 1981 to 2010 long term average.
Good times ahead for Arctic shipping, trade and tourism? Not much of a future for polar bears struggling for survival, or for people whose livelihood and way of life depends on reliable ice cover.

Can environmentalists trump Trump’s climate plans?
When it comes to the latest data on the state of the Arctic sea ice, the Greenland ice sheet or other key features of the cryosphere, the chances are NASA will have been involved in providing it. For those of us interested in protecting our icy regions against climate change, US President-elect Donald Trump’s plan to scrap NASA’s climate research and shift the funding to space exploration is alarming, to say the least.
Why the world needs NASA – not just for space
Two of my colleagues at DW talked to leading scientists about Why Trump scrapping NASA climate funding is bad news for our planet. Thomas Hollands from the German polar agency the Alfred Wegener Institute explains the essential role played by NASA’s network of satellites in providing data for climate researchers the world over.
“Scientists around the world depend on NASA for a variety of information – from measuring the state of the Earth’s atmosphere and the shape of its gravity field, to observations on glacier melting, sea ice formation, forest loss and urban growth”, the article says. It goes on to explain how important it is to have continuous measurements over time to be able to establish trends and changes.
Presumably, of course, if the Trump administration makes good on election promises to revive the US coal industry, there are those who would find it advantageous to get rid of any technology that can measure the extent of the impact of fossil fuel emissions on the world’s climate. A scenario to be avoided at all costs.
So I was interested to read a piece on the news agency AP this week headlined “Trump rollback of Obama climate agenda may prove challenging”. I hope “challenging” will turn out to be an understatement.
The story, by Michael Biesecker, says a President Trump would be in a strong position to dismantle some of President Obama’s efforts to reduce carbon emissions:
“But experts say delivering on campaign pledges to abolish the Environmental Protection Agency and bring back tens of thousands of long-gone coal mining jobs will likely prove far more difficult for the new president”, Biesecker writes.
Environmental groups are gearing up to defend Obama’s environmental legacy in court. Sierra Club Executive Director Michal Brune is quoted as saying “we intend challenging every single attempt to roll back regulations on air, water and climate”, and that his group is already hiring additional lawyers. It does not surprise me that fundraising for environmental causes has also spiked since Donald Trump’s victory.
The question is just how much the President is able to do and what tools are available to opponents to stop him.
The powers of the President
Many legal experts believe Mr. Trump would be able to cancel the Paris Climate Treaty, as he threatened to do when he was campaigning (although his stance has shifted slightly in the meantime). It is not a treaty and was not approved by the (Republican-controlled) Senate. The future president could also order the EPA – where the transition team is being led by a climate skeptic leading a think-tank funded by the fossil fuel industry – not to take the action required to meet the US commitment to cut emissions.
It seems, though, that it is not that easy to dismantle EPA regulations which have already been finalized and implemented. Jody Freeman, director of the environmental law program at Harvard Law School, is quoted as saying “the agency has already built up a very strong record to support those rules”. Ultimately, “it can be very hard to do an about-face.”
From the legal point of view, the President cannot get rid of the EPA without congressional approval – which could be prevented by filibustering. (He could, of course, slash its budget).
When it comes to abolishing NASA’S climate research programme, Mr Trump will also find himself facing some tricky hurdles.
“NASA’s study of earth science is currently mandated by federal law, which means voiding the program would require congressional action”, AP writes. That too means Democrats could block things using a filibuster.
What happened to common sense?
Ideally, common sense and concern for the wellbeing of people and the health of the planet we live on should ensure that Obama’s environmental and climate policies are not turned around. The advances in renewable energy also mean it makes economic sense to shift away from fossil fuels to wind and solar. In fact, it seems the courts will have to tackle the ins- and outs in lengthy and costly investigations.
This past week, in the USA, a group of American youths officially won the right to sue the government of the United States – the world’s second-largest greenhouse gas emitter after China – for failing to curb climate change. The Oregon district court upheld the main argument, that “the government has known for more than 50 years that the carbon dioxide produced by burning fossil fuels was destabilizing the climate system in a way that would significantly endanger plaintiffs, with the damage persisting for millennia.” Yet, the court argues, the government has failed to take action, making it responsible for some of the harm caused by climate change.
Here in Germany, there is also a court case in process, which could set a precedent. A farmer and mountain guide in the Peruvian Andes is suing the German energy giant RWE. Saúl Lliuya from Huaraz says his home is at risk of flooding, as it lies beneath a melting glacier in the Andes mountains. He argues that the company’s coal power emissions contribute to climate change, and so RWE should have to pay a share of measures to protect his home. But RWE says there is no direct link connecting CO2 emissions to the danger of flooding. Lliuya is being supported by the environmental organization Germanwatch. In my Living Planet radio show this week I broadcast an interview with the organisation’s policy director, Christoph Bals.
The plaintiff’s argumentation is that because RWE has produced 0.5 percent of all global emissions since the industrial revolution, the company should at least pay 0.5 percent of the measures to protect the farmer and his home town from flooding as the glacier above it continues to melt. Bals sees it as a major achievement that the case is being dealt with in the German court as one that could set a precedent. Even if the lawyers are not able to prove a direct link and win the case, he says getting to this stage is a demonstration that it is possible to go to court against companies like RWE on climate grounds.
“From now on this is one of the options on the table. I am sure that as soon as we see in the world that we will not stay below two degrees or 1.5 as said in the Paris Agreement, those cases will be much more likely – and it will be much more likely also that the individual court will decide you are right. So for the future this would be one major option if we don’t get a political solution”.
There has to be some food for thought in there for Mr. Trump and his advisors. Interesting times, indeed. And environment and climate advocates have their own trump cards in their hands.

New report sees Arctic melt on course to tip global climate
Scientists say the Arctic archipelago of Svalbard has seen such extreme warmth this year that the average annual temperature could end up above freezing for the first time on record. Ketil Isaksen of the Norwegian Meterological Institute said today the average temperature in Longyearbyen, the main settlement in Svalbard, is expected to be around 0 Celsius with a little over a month left of the year. He called the abnormal warmth “shocking” and beyond anything he could have imagined 10 years ago. The normal yearly average is minus 6.7 C.
And that is not the only shocking thing going on up north. The Arctic sea ice is melting in November. Temperatures in the region are 20 degrees Celsius above usual. Reindeer are dying across Siberia. Polar bears are stranded on land. It’s hard to keep up with the extent and speed of climate change in the far north of the planet. And we in the media have to be aware of the danger that the reports become so commonplace the “new normal” no longer arouses interest.
Warming, warming, hot
Yet the ever faster melting of our Arctic ice could spell disaster even for distant regions of the planet. What happens in the Arctic doesn’t stay in the Arctic, as discussed here on the Ice Blog many times before. But a new, key report launched today indicates that the effects of increasingly rapid Arctic warming could be set to push global climate change out of control.
The Arctic Resilience Assessment (ARA) is an Arctic Council project led by the Stockholm Environment Institute and the Stockholm Resilience Centre. It is based on collaboration with Arctic countries and Indigenous Peoples in the region, as well as several Arctic scientific organizations. The ARA (previously Arctic Resilience Report) was initiated by the Swedish Ministry of the Environment as a priority for the Swedish Chairmanship of the Arctic Council (May 2011 to May 2013) and is being presented under the US Chairmanship. It aims to synthesize knowledge on Arctic change and how people and the ecosystem are coping with it, bringing the wide range of different factors together.
“Environmental, ecological, and social changes are happening faster than ever in the Arctic, and are accelerating. They are also more extreme, well beyond what has been seen before. This means the integrity of Arctic ecosystems is increasingly challenged, threatening the sustainability of current ways of life in the Arctic and disruption of global climate and ecosystems”, the report says.
Beyond the tipping point
The researchers issue a stark warning: “Some changes are so substantial (and often abrupt), that they fundamentally alter the functioning of the system: an ecological “tipping point” has been crossed. The report examines 19 of these “tipping points” or “regime shifts”, as they are also known: “They affect many ecosystem services that are important to people within and outside the Arctic: from regulating the climate, to providing sustenance (e.g. through fishing)”, the experts tell us.
“The consequences of some of these shifts are likely to be surprising and disruptive – particularly when multiple shifts occur at once. By altering existing patterns of evaporation, heat transfer and winds, the impacts of Arctic regime shifts are likely to be transmitted to neighbouring regions such as Europe, and impact the entire globe through physical, ecological and social connections”, the report says.
The tipping points discussed in the report include the replacement of white ice and snow, which reflect heat back into space, by darker green vegetation or ocean water, which absorbs more heat, higher releases of methane and changes to ocean circulation and so weather patterns around the globe caused by an influx of melting snow and ice.
Major impacts inevitable?
Johan Rockström, director of the Stockholm Resilience Centre and co-chair of the five-year study said in a statement: “If multiple regime shifts reinforce each other, the results could be potentially catastrophic.… The variety of effects that we could see means that Arctic people and policies must prepare for surprise. We also expect that some of those changes will destabilize the regional and global climate, with potentially major impacts”.
The report stresses that many of the changes and feedback effects in process are poorly understood and in need of much more research.
“Arctic ecological protection is now a global concern, and worldwide monitoring is inadequate”, the authors write.
Political “regime shift”?
To reduce the risk of these tipping points, strong action would have to be taken to mitigate climate change, the authors conclude. Aha. Now there’s the rub.
In the Guardian, Fiona Harvey notes the report comes at a critical time in politics, with Donald Trump’s announcement this week that he plans to take away NASA’s budget for climate science and put it into space exploration. She quotes Marcus Carson of the SEI, co-editor of the report:
“That would be a huge mistake…It would be like ripping out the aeroplane’s cockpit instruments while you are in mid-flight”.
If Mr. Trump also makes good his pledge to revive the US coal industry and abandon the Paris Climate Agreement, the chances of halting warming and the climate feedback mechanisms which could spell disaster would seem to be melting away along with that Arctic ice. Not so tasty food for thought this weekend. Well, I could distract myself by getting out the lawnmower. It has been so warm here this week the birds are chirping like spring and the grass has started to grow again.

Arctic Council – 20 years in a warming world
20 years does not really seem like a long time. But when it comes to climate change in the Arctic, the last 20 years have brought more change than centuries gone by.
After the warmest winter in the Arctic since records began, the sea ice has declined to its second-lowest level ever. And the “second-lowest” tends to divert attention from the fact that the sea ice cover has dwindled to nearly 2.56m sq km less than the 1979 to 2000 average. That’s the size of Alaska and Texas combined.
So the Arctic Council is celebrating its twentieth birthday at a time when concern over the impacts of planetary warming on the high north could hardly be greater.
I had the chance to interview Julia Gourley, the US Senior Arctic Official on the telephone ahead of the birthday. The US, of course, currently holds the two-year chairmanship of the body. I asked her how the Council had changed over the past 20 years.
“In the early days the Arctic state focused almost exclusively on environmental protection and science issues. But over the 20 years the countries have shifted the focus a bit. Certainly we still spend a lot of time trying to understand the environmental change that’s been going on. We spend much more time now on sustainable development issues, which in the Council generally refer to issues that affect the people of the Arctic, in particular the indigenous people. We’ve learned a lot in 20 years about the people who live there and the challenges they face.”
And those challenges are increasing all the time, especially because of the rapid pace of climate change.
Melting ice, easier access
The increase in human activity, as remote Arctic regions become more easily accessible has turned protecting the region into a whole new ball game. Gourley cites cruise ships, offshore oil and gas development , fishing and shipping as issues which have moved up the agenda.
Clearly, this means more work for the Arctic Council – and has also brought a lot more global interest in the region:
“We have 32 observer entities now, 12 of whom are countries. There are many more in the queue that are seeking observer status. What happens in the Arctic affects the entire planet, so countries all over the world are becoming interested in the region”.
With a big player like China taking a huge interest in the Arctic and looking to establish ports and secure its own access to the region, and political tensions between some of the Council members, such as Russia and the EU or the USA itself, the shadow of conflict always seem to be lurking in the background. Gourley is keen to play this aspect down. She stresses the key role of the Council in keeping the Arctic peaceful and encouraging cooperation. The USA, she says, welcomes the increasing interest by non-Arctic states – although, she adds, each of the Arctic states has their own views on that.
“We feel like we have a lot to learn as a group of Arctic states still about how the Arctic affects the rest of the world, and the more countries that are in the room listening to the discussion and learning from it and can contribute to it, the better. So we encourage non-Arctic countries that have particular expertise, to contribute to the work of the council – the scientific work, the technical work, economic work.”
When it comes to regulating activities in the Arctic, the Council itself is not a regulatory body, but it contributes expertise to others.
“When it comes to shipping, the International Maritime Organisation is the regulatory authority all over the planet. But the Council has a strong interest in shipping in the Arctic, and so the Council has done some seminal work on the Arctic shipping situation, including a very important piece of work in 2009 called the Arctic Marine Shipping Assessment. That was the first time anyone in the world had looked deeply into the state of shipping in the Arctic in the face of climate change and reducing sea ice. That study is still cited today”.
When it comes to regulating offshore activities like mining and fishing, the Arctic states also have their own regulatory regimes, “ so it’s sort of a mix of regulatory activity by lots of different entities”, Gourley explains.
The US Arctic representative is bound, of course, to take up a diplomatic stance. But while she stresses the Council’s efforts to keep tensions low and foster cooperation rather than conflict, she does make one qualification:
“The tensions in other parts of the world haven’t affected the work of the Council. That said, of course we all have our own national views about a lot of the issues that face the Arctic. But as to working together as a group of eight countries, together with the observer states and NGOs, it really has worked quite well. We’ve managed to carve out a space that we can work in collaboratively. Now, that doesn’t mean that will always be the case. As things change in certain parts of the world it’s not easy to predict what could happen in the Arctic. But at least up to this point, we’ve been able to work together quite well.”
Presumably, with climate change having such a strong and rapid impact on the Arctic, there are bound to be increasing differences of opinion when it comes to striking a balance between preserving the Arctic as it is on the one hand, and on the other developing commercial and industrial activities. The US representative was quite realistic on this one:
“Yes, that’s a real tension. I think that chapter of the Arctic story is still being written. Each Arctic state comes at those questions in their own waters and their own exclusive economic zones differently, and each country’s regime is slightly different. So it’s hard to say there’s a single answer to how we resolve those questions. But it is something that is very real. It’s of concern in particular to a lot of Arctic indignous people, who want to live traditionally but also realize that modernity is moving into their world and in some cases economic development is very necessary to create good jobs and include living conditions. So it is a very real, very alive debate.”
Indeed. The Arctic conundrum in a nutshell.
Tackling black carbon
What happens in the Arctic doesn’t stay in the Arctic – and pollution produced in the rest of the world doesn’t stay out of the Arctic.
While the UN has its own body tasked with combating climate change, there are other climate-forcing agents which affect the Arctic particularly strongly, such as black carbon or soot. The Arctic Council sees this as an area where it has a key role to play:
“Black carbon itself is not part of the UNFCCC, so it’s not part of any global regulatory regime. So we are working in the Council on ways to reduce black carbon emissions voluntarily. So I think that’s going to have some very positive results.”
At the end of our talk, I wanted to know whether optimism outweighed concern or vice versa when it comes to the future of the Arctic in our warming world. The answer didn’t surprise me. But the underlying sentiment that in spite of all the tension in the world and the feeling that climate change is gathering momentum and happening ever faster, we all have to pull together, is a message I can subscribe to:
“I think I feel optimistic in a way. Certainly, the melting that’s happening in the Arctic is potentially hugely problematic for the world. I think the science is pretty clear on that front. And it’s not going to change overnight. Even if the Paris Agreement is fully implemented right away, it’s a long time before the Arctic environment can stabilize. But when we have countries working together, if we can keep the conversation going, and we can encourage all of us in the Arctic and Arctic observer states, to work together to keep the conversation going, even if it’s slow, and to keep communication lines working, I think we do have room to be optimistic about that area of the world.”
The next 20 years are not likely to be less challenging than the last for the Arctic Council. On the contrary. You have your work cut out for you. Good luck – and happy birthday.
