Why Africa has to worry about melting Greenland ice

Working for an international broadcaster which has Africa as one of its key target groups, I often find it difficult to interest some of my colleagues in what is happening in the Arctic. So my attention was caught instantly when I came across an article by Chelsea Harvey in the Washington Post: A climate chain reaction: Major Greenland melting could devastate crops in Africa.

Trump’s alternative reality? No warming, cool oceans, intact coral

Melting or not? (I.Quaile, Greenland)

“Irene, have you heard the news? Looks like Trump has pulled out of the Paris Agreement.” While the US President kept the suspense up until Thursday night – has he, hasn’t he, will he, won’t he -I struggled to reconcile his action with what I was hearing from a wide spectrum of highly intelligent people with decades of research and experience to their credit.

I was in Kiel this week, on Germany’s Baltic coast, attending a working meeting of the scientists involved in BIOACID, a national German programme (supported by the BMBF, Federal Ministry of Education and Research) to investigate the “Biological Impacts of Ocean Acidification”.  It has almost run its course, eight years of research in the bag.

And what I was hearing did nothing to allay my concern about the impacts of  our greenhouse gas emissions.  We are rapidly and undeniably changing the planet we live on – land and sea. And that applies particularly to the Arctic.

The scientific evidence

Can President Trump really fail to see the dangers of our human interference?  Is he really oblivious to what climate change is doing to the ocean that covers 70 percent of the surface of our planet?

Maybe he lives in a parallel universe, where alternative facts prevail.

Back in 2010, I was able to witness the work of some of the scientists assembled in Kiel this week at first hand, as they lowered mesocosms, a kind of giant test tubes, into the Arctic Ocean off the coast of Svalbard. The aim was to find out how the life forms in the water would react to increasing acidification of their environment, as our greenhouse gas emissions result in more and more CO2 being absorbed into the ocean.

Drawing the threads together

Ulf  Riebesell is Professor of Professor of Biological Oceanography at, GEOMAR, the Helmholtz Centre for Ocean Research in Kiel, and the coordinator of BIOACID.

When I first met him, he was kitted out in survival gear, supervising the transport and deployment of the mesocosms from Germany up to the Svalbard archipelago. He doesn’t need the cold-weather gear this week, in a summery Kiel, where he gathered representatives of the different working groups involved in the German project to draw some threads together as the project approaches its conclusion in November.

Good timing. The results will be ready to hand to the delegates attending this year’s UN climate extravaganza, COP23, in Bonn. Another key piece in the jigsaw puzzle of how climate change is affecting the world we live in and will determine the future of coming generations.

All creatures great and small

The scientists assembled represent a wide range of expertise.  From the tiniest of microbes through algae, corals, fish and the myriad organisms that live in our seas- they have been trying to find out what happens when living conditions change for our fellow planetary residents – and  how all this affects  an ever-increasing population of  humans and the complex societies we live in.

The ocean is changing at an unprecedented rate.  It is becoming warmer, even in the depths, and it is becoming more acidic.

The work of Riebesell and his colleagues has shown that in our rapidly warming world, the CO2 that goes into the ocean is reducing the amount of calcium carbonate in the sea water, making life very difficult for sea creatures that use it to form their skeletons or shells. This will affect coral, mussels, snails, sea urchins, starfish as well as fish and other organisms. Some of these species will simply not be able to compete with others in the ocean of the future.

The Arctic predicament

Acidification is not something that affects all regions and species equally. Once again, the Arctic is getting the worst of it. Cold water absorbs CO2 faster. Experiments in the Arctic indicate that the sea water there could become corrosive within a few decades, as Ulf Riebesell has told me on several occasions since I first met him on Svalbard in 2010. “That means the shells and skeletons of some sea creatures would simply dissolve.”

Scientists warn that a combination of acidification, warming and stressors like pollution of all sorts will ultimately affect the food chain. (Indeed that is already happening).

Warming as usual?

While the BIOACID project comes to an end and the scientists fight for new funding to carry on research into ocean acidification, which requires a combination of field-work and modelling, the world continues on course for far more than the two degrees – or 1,5 set out in the Paris Agreement.

“Ocean Warning” was the cover title on the Economist magazine this week, ahead of next week’s  UN Oceans Conference in New York.

“The Paris Agreement is the single best hope for protecting the ocean and its resources”, the magazine reads. But it stresses: “the limits agreed on in Paris will not prevent sea levels from rising and corals from bleaching. Indeed, unless they are drastically strengthened, both problems risk getting much worse. Mankind is increasingly able to see the damage it is doing to the ocean. Whether it can stop it is another question”.

Bending the truth?

At the meeting in Kiel, I asked Professor Hans-Otto Pörtner, the other coordinator of BIOACID, senior scientist at the Alfred Wegener Institute and co-chair of the IPCC Working Group 2 for his view of the current situation,  with US President Trump getting set to leave the Paris Agreement:

“Climate change is clearly human made, responsible leadership means that this cannot simply be denied or ignored. I think this is a call for better education and information of the public so that it cannot be misled by bending the truth – and this is what it comes down to. As the last report of the Intergovernmental Panel on Climate Change (IPCC) put it: “Without additional mitigation efforts beyond those in place today, and even with adaptation, warming by the end of the 21st century will lead to very high risk of severe, widespread and irreversible impacts”. In its previous analysis of decision-making to limit climate change and its effects, the IPCC also noted that climate change is a problem of the commons, requiring collective action at the global scale. Effective mitigation will not be achieved if individual agents advance their own interests independently.”

Call to action

Indeed. We are all in this together.

But there is not only bad news:

“It remains to be seen to what extent U.S. emissions will be driven by federal policy, or actions at the State and city level, or by market and technological changes”, Professor Pörtner told me.

There is, it seems to me, an upside to President Trump’s decision to live in his own alternative reality. It galvanizes those of us who live in the real world to make sure climate action goes ahead. China and the EU closed ranks this week. States, companies, civil societies and committed individuals across the USA are stressing they will press on with the green energy revolution regardless.

In the interests of the icy north – and the rest of the planet it influences so considerably – we really have no choice.

Cheap oil from the Arctic? Fake news, says climate economist Kemfert

Nothing fake about melting ice. Eiders, off Svalbard (I.Quaile).

This week I came across an interesting publication about to come on to the German market.

“The fossil empire strikes back” (Das fossile Imperium schlägt zurück) is the translation of the catchy title of a new book in German by  Professor Claudia Kemfert, head of the department of energy, transportation and environment at the German Institute for Economic Research in Berlin (DIW Berlin,) and professor of energy and sustainability at the Hertie School of Governance, in Berlin.

She has also acted as advisor to the German government, the European Commission and is on the steering committee of the renowned Club of Rome.

A fossil fuels revival: happening now, or alternative facts?

I called her up to record an interview for our Living Planet radio show to find out what was behind the headline, and the sub-title: “why we have to defend the “Energiewende” (energy transition)  now.

Prof Kemfert believes the fossil fuels sector is really working hard at making a comeback. That, she says, is not fake news, but the fossils lobby makes use of the latter in its attempt to turn the clock back in terms of energy production.

Kemfert argues for renewables. Copyright: Neuberg, Sebastian Wiegand

While the global transition towards renewable energy has been successful in recent years, with the costs of alternative energies reduced, the Paris Agreement signed and ratified, now, she says, the fossil fuels sector is striking back.

She says they do it by spreading fake news, creating myths about restrictions on cars, speed limits, blackouts, globally, but especially in the USA under the Trump administration. So, she argues, we have to defend the energy transformation. The window of opportunity for climate action is still open, but we are losing time.

The power of fake news

Kemfert’s aim is to debunk the myths, which she is convinced are being used to give renewable energy a bad image. Some of the examples she cited to me are false claims that renewables are more expensive, or that reliance on alternative energies will mean blackouts.

“This has never happened in Germany”, she notes, the country that gave the “Energiewende” its name and pressed ahead with the transition to renewables in recent years.

So how can fake news of this kind make such an impact that Kemfert and other like-minded experts are worried about an oil and coal revival?

“If you repeat this all the time, and repeat it on social media, people think it’s true”, she told me.

“The danger is that they can be successful”.

“The global energy transition is in danger”, she is convinced. “We are losing time to bring greenhouse gases down and help the planet to survive.

“The lobby of the fossil empire is extremely strong… the whole campaign with myths and fake news is really successful, because a lot of people believe what they say”.

So are the fossil fuel lobbyists just better at getting a message across than the other side? There could be something to that, Kemfert agreed. She says the “green lobby” is not aggressive enough. People think “we are the good ones, the energy transition comes by itself”- this is not true. Now it’s time to fight for it”.

We still have a window of opportunity, says Kemfert (Pic. I.Quaile, Alaska)

Time to march?

She calls on all scientists and people who want to protect free and democratic science,  to take part in the Marches for Science, planned to take place round the globe on April 22nd.

Of course I wanted to know how she thought the global counter-attack by the “fossil empire” would impact the Arctic.

Yes, she said, this push for a fossil fuels revival could provide additional motivation to those who would like to push ahead with Arctic drilling, as climate change makes for easier and less expensive access:

“There are some aggressive industries, especially coming from the oil and gas sector, who have interest to drill for oil in the Arctic region.

For them, she says, easier access thanks to climate change would be “a nice, so-to-say side effect”.

But for the planet as a whole, climate change is so dangerous that any potential short-time business benefits are just not worth thinking about, says Claudia Kemfert:

“As a climate economist, I cannot say this (oil from the Arctic) makes economic sense, because the costs of climate change are much higher than lower costs, for example, for drilling oil in the Arctic. The costs of global climate change are so high that it cannot outweigh the cost reduction of oil drilling in the Arctic when there’s low ice. We have to move away from oil and gas, this is why it’s more economically efficient to go for an energy transition instead of drilling in areas where we have climate impacts, we are causing environmental difficulties and where we know that burning these fossil fuels will create climate change. That’s really the wrong way to go”.

Kemfert’s book is only being published in German at the moment, but there is more info on her home page, and a longer version of the English interview I conducted with her will be coming up soon on Living Planet and on the DW website.

Arctic sea ice: is the minimum maximum the new normal?

Even the winter sea ice is waning (Off Svalbard, pic. I.Quaile)

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.

Sea ice going, going, gone? (Photo: I Quaile, off Svalbard)

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.

Data from satellites is key. Reception centre at KSAT in Tromso, Norway, Pic. I Quaile)

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.

NOAA (climate.gov, “science & information for a climate-smart nation”!) said in its statement:

“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.

Sled dog – out of work? (I.Quaile, Greenland)

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”.

Will new climate scientist on board influence Exxon?

Can a climate scientist help cut fossil fuel emissions to save melting Greenland ice? (I.Quaile)

Can a climate scientist help cut fossil fuel emissions to save melting Greenland ice? (I.Quaile)

Last year I had an interesting guest in the studio here at Deutsche Welle. We talked for a good half hour about climate change and the ocean and the need for the Paris Agreement to be put into action, and whether we can still save the Arctic ice as we have known it in our lifetimes.
Excerpts from the interview were broadcast on Living Planet and published online.

Susan Avery is an atmospheric scientist. She was President and Director of the renowned Woods Hole Oceanographic Institute from 2008 to 2015, and became a member of the scientific advisory board to UN Secretary General Ban Ki Moon in 2013. She was in Bonn for a lecture organized by Björn Müller-Bohlen from the department of strategic partnerships at the Forum of International Academic Sciences in Bonn, to explain to people here how climate change is affecting the ocean.

I was surprised to say the least when I saw that from the beginning of February Dr. Susan K. Avery had been elected to the board of directors of ExxonMobil.

Topsy-turvy world?

So the former Exxon chief Rex Tillerson has taken the key post of Secretary of State in the Trump administration,  climate skeptic Scott Pruitt takes over the EPA, the world worries about the future of the climate and the environment –  and a leading climate scientist has joined the “largest publicly traded international oil and gas company and one of the largest refiners and marketers of petroleum products”, as ExxonMobil describes itself. It is also at the centre of a huge controversy over claims that it denied climate change, covering up facts and funding climate skeptic bodies. Interesting times indeed. (The Dawn of the Trumpocene?) What are we to make of it all?

I emailed Dr. Avery to try to arrange another interview to discuss her motivation and expectations. She did respond swiftly, telling me she was “honored to be elected to the Board and look forward to serving in that capacity.” But interview requests are being handled by Exxon.

Reactions to her appointment have been mixed, ranging from those who see this as a mere greenwashing type of move by Exxon, and those who think this represents a gradual shift in thinking in the corporation (pragmatic shift to renewable energies given the problems ahead for fossil fuel companies?)  and the optimists who think this could possibly even be a chance for a climate expert to influence the policies of the fossil fuel giant and a sign that the times are ‘a changin’.

From the “horse’s”mouth

I decided to have another look and listen to the interview I recorded with Dr. Avery last year, to remind myself and those who will be watching her actions with interest, of what she stands for when it comes to protecting the climate, the ocean and the Arctic.

She is certainly in no doubt about the human factor in climate change. When I mentioned that we humans had been “interfering” with the climate, she laughed good-naturedly at my under-statement, and went on to elaborate on how we are increasing the temperature of the atmosphere by infusing carbon into it. She clearly named fossil fuels as a cause. So what, I wonder, will she be telling the board of ExxonMobil?

Our subject was the effect of greenhouse gas emissions on the oceans in particular. She stressed that while 25 percent of the carbon dioxide we release goes into the atmosphere, a stunning 93 percent of the extra warming created is in the ocean. I went on to ask her about the impacts:

“The carbon dioxide we’ve put into the atmosphere already and the heating associated with that means that we’re already pre-destined for a certain amount of global temperature increase. Many people say we have already pre-destined at least one and a half degrees, some will say almost two degrees. That’s why it’s really important to address the warming questions. And I was really pleased to see the Paris Agreement finally signed off on.”

Fossil fuel threat to the ocean

With the future of US participation in implementing the Paris Agreement very much up in the air under the Trump administration, one wonders how Avery is going to push the decarbonisation of the economy necessary to keep anywhere near the two degree limit, on the board of one of the world’s biggest oil and petroleum concerns.

She also stressed in her talk with me the huge threat to the food chain posed by ocean acidification, as carbon dioxide emissions change the PH of the ocean.

“Our coral reef systems and a lot of our ecosystems in the ocean are having a battle with warming, and those ecosystems that involve shell production and reproduction, as in our reef systems, are also battling acidification issues. This is really critical, because it attacks a lot of the base of the food chain for a lot of these eco-systems. “

Another of the threats to the ocean and the creatures in it is pollution, and Avery told me her time as head of Woodshole was a time of “many crises  in the ocean”  – including the  Deep Water Horizon oil spill:

“That was a real challenge for us in terms of looking at the technologies we have in a different way, solving a different type of problem, and from these crisis moments we learned a lot about our science and our technology, and how to improve it and go forward.”

Well, here’s hoping that knowledge and Dr. Avery’s expertise here will help the company where she is now on the board.

Kudos for the journos

Another point that came out of our interview was Avery’s firm belief in the key role the media have to play in explaining what is happening to our climate and environment to “ordinary people”.

“It is things like Living Planet and others that really begin to educate people and involve people in understanding their environment and their planet,” she said in the DW studio.

As host and producer of Living Planet together with my colleague Charlotta Lomas, it was good to have that acknowledgement from a leading scientist and adviser to the UN. Avery also mentioned progress in recent decades in raising public awareness of environmental issues, such as pollution or acid rain, thanks not least to media coverage.

Unfortunately that job is not made any easier – especially in the United States – with an administration that tries to gag journalists and, it seems, any organization that does not spread the information the government think should be spread.

Motives and methods

So what motivates someone like Susan Avery to take on a controversial position like board membership on a company whose main business results in harmful changes to the planet which she has been working for years to publicise? Perhaps another snippet from the interview can shed some light, when I asked my guest Avery how she had come to be a member of the board of advisors to Ban Ki Moon (not that I would compare that to joining ExxonMobil).

“I was intrigued by the opportunity to play on a stage level that was very high politically, and making sure that science was interfaced in a number of dimensions, into the policy and decision-making process at that level. The committee itself is a wonderful board in terms of the different disciplines represented, different countries represented, different perspectives we all have on the science and the environment, and on human health issues, that the UN needs to be cognizant of.”

Clearly, this is a woman who likes to be in influential positions – and to bring different camps and expertise together:

“We talked a lot about science, the policy-society interface, the role and engagement of stakeholders, those are governments at all levels, the business community, and conservation.

What about the Arctic?

Of course one of the Iceblogger’s  most urgent concerns is what climate change is doing to the polar regions.  With record temperatures in the Arctic and record low sea ice cover, I asked Avery to sum up the impacts for our Living Planet listeners. She expressed her concern that “we are beginning to see a very rapid increase in ice loss in the Arctic”. She cited the melting of the big land ice glaciers as a major contributor to sea level rise. She talked of how not only atmospheric temperature but warming ocean waters are degrounding glaciers and melting ice from below:

“That is a major concern for sea level rise, but also because when the land-based ice comes into the ocean, you get a freshening of certain parts of the ocean, so particularly the sub-polar north Atlantic, so you have a potential for interfacing with our normal thermohaline circulation systems and (this) could dramatically change that. Changes in salinity are beginning to be noticed. And changes in salinity are a signal that the water cycle is becoming more vigorous. So all of this is coupled together. What’s in the Arctic is not staying in the Arctic. What’s in the Antarctic is not staying in the Antarctic. I would say the polar regions are regions where we don’t have a lot of time before we see major, massive changes”.

So let us hope Dr. Avery will be able to convince her fellow board-members and the decision makers at ExxonMobil about that – and about what has to happen. Fossil fuel emissions in general have got to go down. And the fragile Arctic in particular is in need of protection. Clearly, she has her work cut out for her.

Is there still time?

Reporting Avery’s appointment to the ExxonMobil board, the news agency AFP quotes her as saying:

“Clearly climate science is telling us (to) get off fossil fuels as much as possible.”

I asked her whether she believed, given that we have already put so much extra CO2 into the atmosphere and the ocean, that there was any way we would be able to reverse what is happening in the Arctic. Her reply – unsurprisingly – was not too reassuring:

“I don’t have an answer, to be honest. I think we’re still learning a lot about the Arctic and its interface with lower latitudes, how that water basically changes circulation systems, and on what scale. (…)We know so little, about the Arctic, the life forms underneath the ice (…) And I think it’s really important, because the Arctic will be a major economic zone. We’ve already seen the North-West Passage through the Arctic waters, we’re going to see migration of certain fisheries around the world, and we don’t even know completely what kind of biological life we have below that ice. We have the ability to get underneath the ice now. I call these the frontiers, of the ocean, and that includes looking under ice. It’s a really exciting time.”

If that excitement can be put into protecting the fragile polar ecosystems rather than taking advantage of our emissions misdeeds to date to use easier access for commercial exploitation, I am all for it.

ExxonMobil remains a primary target of environmentalists. It has been the subject of investigative reports by environmental news nonprofit Inside Climate News and others, saying it “manufactured doubt” about climate science even while contradicted by research by its own climate scientists. The company says the reports are biased, but faces government investigations over the controversy. In January, a Massachusetts court ruled the oil giant must turn over 40 years of documents on climate change, in a win for Massachusetts Attorney General Maura Healey, who has described the probe as a fraud investigation.   ExxonMobil has countersued against Healey, arguing she lacks jurisdiction in the matter.

As I indicated above, there are environmentalists who were not impressed by the appointment of a climate scientist to the fossil fuel giant’s board. AFP quotes Shanna Cleveland of Ceres, a nonprofit group that works on shareholder actions to pressure companies to address climate change. She called the move a “really good first step, but not much more than that”, and fears Susan Avery could be  a “lone vote in the wilderness” on climate change given ExxonMobil’s record on the issue.

The climate advocacy group 350.org dismissed the appointment as “little more than a PR stunt.”

Scientists to the fore

But at a time when some critics say the Trump administration is threatening environmental democracy in the USA, I would prefer to see Dr. Avery’s new position as a move in the right direction, if a tiny one.

With scientists gearing up to march on Washington in the not-too-distant future, we can do with experts who acknowledge, understand and call for action on climate change on every level, in every corner.

Susan Avery described her time on the UN scientific advisory board in her interview with me here in Bonn as as “a fun exercise.” In the current climate, I cannot imagine the same will apply to being the climate advocate on the board of a controversial fossil fuels giant like ExxonMobil.
