Antarctica: Science and Diplomacy

Debate between James Gray and Thangam Debbonaire

Tuesday 28th January 2020 Westminster Hall

[James Gray]

Almost nobody picked me up on that. If we asked people out there, they would say, “Antarctica? Oh yes—polar bears.” But that is not the case. Polar bears are in the north, penguins in the south. It is important to remember that. The north is a sea, the Arctic ocean; the south is landmass, covered by ice. It is completely different.

Most people probably know about Scott and about Roald Amundsen. Most people might know a bit about Shackleton, although that is rather specialist knowledge. However, at least until the great Sir David Attenborough highlighted these issues for us all in “Blue Planet II” and more recently in “Seven Worlds, One Planet”—both superb TV productions—most people did not know much more about Antarctica. I hope that today’s debate will help to spread the word about the great white continent and some of the challenges it faces.

I particularly wanted to hold the debate today because it is within a day of the 200th anniversary of the first occasion on which the continent was sighted. A Russian by the name of Bellingshausen claimed in retrospect—he did not claim it at the time—to have sighted the continent for the first time on 27 January 1820. In 1819, the previous year, I am glad to say that a Brit, William Smith, had sighted the islands to the north of the continent and subsequently made a landing there. He came back in 1820 with a Royal Naval officer, Edmund Bransfield, and they definitely sighted the continent on 30 January 1820, a couple of days later than Bellingshausen claimed to have done so. I think it was a great British first sighting.

Is it not astonishing that that happened after the battle of Waterloo? By that time, this country was entering into the industrial revolution, yet we had not even sighted Antarctica, far less landed on it. We followed that up: Weddell sailed 74° south a couple of years later and discovered what would become the Weddell sea, and in 1841 James Clark Ross, on HMS Erebus and Terror—ships famous because they were subsequently lost on the Franklin expedition, seeking the north-west passage—got through the ice, into the Ross sea and right up to what is now known as the Ross ice shelf. Then, of course, came the great era of Antarctic exploration, just before the first world war, with Scott, Amundsen, Shackleton and all that. We know about all that.

Rather curiously, after the first world war not much happened in Antarctica until well after the second world war. The importance of the continent for the world’s climate in particular, its potential for scientific discovery and the need to save it from either commercial exploitation or militarisation became known from about 1950 onwards. That led to the signing of a huge milestone in diplomatic activity, the Antarctic treaty, the 60th anniversary of which we celebrated during the Antarctic Parliamentarians Assembly just before Christmas.

In the 60 years since we signed the Antarctic treaty, it has ensured that there is neither commercial exploitation nor any kind of militarisation on the continent. It is kept for peace and for science, and it is entirely free of commerce. That in itself must be a significant diplomatic triumph. One can think of no other treaty in the world that has preserved an entire continent for 60 years so far and, I hope, for many years to come. I am glad that Britain took a leading part in arranging the Antarctic treaty 60 years ago.

Now, however, we must move forward from the relatively peaceful times we have had in Antarctica over the past couple of hundred years, because some astonishing and appalling things are occurring down there. Unless we do something about it now, significant changes will come in Antarctica. I remember attending the Earth Summit in Rio as long ago as 1992, when I was a special adviser to the then Secretary of State. It was a great summit, but we have not done the things we claimed we would do. We have allowed climate change to get worse and worse ever since, and Antarctica not only suffers the worst consequences of climate change, but creates and amplifies it.

It is interesting that at last year’s conference of the parties in Paris, the Intergovernmental Panel on Climate Change targets did not include the Antarctic ice sheet at all. The Paris COP predictions of a 40 cm rise in the oceans did not take into account the Antarctic ice sheet. Including the Antarctic ice sheet would likely more than double that figure.

Amazingly, the Antarctic ice sheet contains 70% of the world’s fresh water. Think of that: 70% of all the fresh water in the world is in the Antarctic ice sheet, which is definitely showing signs of melting and collapsing into the sea at a most alarming rate. A couple of years ago, an iceberg the size of Manhattan broke off from the Thwaites glacier, leading to a serious international study led by the British and Americans. If the ice sheet were to collapse, water levels could rise by up to 12 feet. The northern hemisphere could be particularly affected by that, because of the way in which oceans flow. If that were to occur, we would not be able to sit in this Chamber—unless we had our snorkelling equipment. We would be well under water.

My friends at the British Antarctic Survey have just come back from a season on the Thwaites glacier carrying out probably the largest and most complex scientific field campaign ever undertaken, to try to discover exactly what is happening to it. They drilled several holes through the ice, to try to provide insight into what happens when the warm water that is increasingly coming south—the Southern ocean is warming up—meets the ice. They think the answer is that the warm water undermines the ice to the extent that, sooner or later, the ice shelf breaks off. That seems to be what happened with that huge iceberg just a couple of years ago. They have deployed robots under the ice, to try to see what is happening down there, and installed a whole host of instruments to measure the effects on the glacier.

The west Antarctic ice sheet is one of the most dramatic pieces of evidence in the world of climate change and of the catastrophe that awaits us if we do not do something about it. This debate is not about climate change, but when looking at the great white continent, the Antarctic, it is terribly important that we think seriously about it. I hope the Minister will do that in a significant way when she responds.

We in the UK have led science in the Antarctic since the very earliest days. There are about 50 research stations there from virtually every nation in the world, including Mongolia, if I am not wrong. When I visited the south pole about three or four years ago—I flew out; I did not ski—I was disappointed by the American permanent research station down there. It is a great, huge black thing stuck on the pole itself, ruining what Scott and Amundsen saw all those years ago.

The flags around the south pole itself were alternately American, British, Norwegian, American, British and so on. For the sake of my photographs, I went around and took all the American flags down and replaced them with Norwegian and British flags, because it is the Amundsen-Scott base. As a result they were very good photographs, but the Americans came out of their base and stuck all the American flags back up again. I meant no disrespect to my great friends in America, but none the less I think Scott and Amundsen would have been surprised by the huge presence of Americans at the base itself.

The British Antarctic Survey does great work. It is refurbishing our base in Rothera, on the peninsula, and of course recently commissioned, and has nearly completed, the RRS Sir David Attenborough, which will make a huge and significant contribution to polar research in both the south and the north.

Last year’s Antarctic circumnavigation navigation expedition—on a Russian ship, the Akademik Tryoshnikov—by Dr Paulsen, who funds us, was the first to take 80 scientists, many of them British. They circumnavigated the entire Antarctic content, taking samples all the way round. That is one of the most significant contributions to Antarctic science for many years. We do a huge amount for science.

The hon. Gentleman is making an excellent and informative speech. I have several declarations of interest to make, including that my mother is in Antarctica at the moment—possibly with the Minister’s relatives. We are blessed with the science that the hon. Gentleman mentions. My niece works on a research project on microbial life in glaciers and has mentioned to me work taking place in Antarctica, under the auspices of Aberystwyth University. Does he agree that we need to support and value that scientific research? That microbial life may offer the clues to address all sorts of problems, as well as having unintended consequences, which will also need researching.

[James Gray]

I am most grateful to the hon. Lady—my constituency neighbour, more or less—for her important contribution. She is absolutely right: the work we are doing now in the south is incredibly important science. However, it is becoming more and more expensive, and we need to increase the amount we spend, through BAS and in other ways, to improve our scientific research. Antarctica is the most brilliant place to research things, quite apart from the continent itself, but we need to significantly increase spending on it, which is well worth doing.

These and so many other challenges and opportunities have been managed so well under the Antarctic treaty. In 1959, 12 countries, the main claimants, came together to agree the treaty. It is a short document, with only 14 articles—often the best documents are the shortest—but has been one of the most effective and long-lasting of all diplomatic treaties. It has achieved its aim of preserving the continent for peace and science, and as a result the continent is unique in having had no military conflict in the 67 turbulent years since it was first signed, which is quite some going.

In the 1980s, the treaty was followed up by the convention on the conservation of Antarctic marine living resources—CCAMLR—which has done great work in regulating and conserving fish stocks and other mammals in the Antarctic and the Southern oceans. That was followed by the environment protection protocol in the early ’90s, which effectively established Antarctica as a natural reserve. That protocol ensures the biosecurity of the continent and regulates tourism, which we think will become a significantly increased problem over the years to come. It plateaued slightly after the banking crisis in 2008, but we now predict its exponential growth, as the hon. Lady mentioned a moment ago, over the next three to five years.

We have to think carefully about how we handle the biosecurity consequences, and the consequences for the continent, of allowing people to visit it. Most people like to go ashore at least once, to one of the places with penguins and so on, but the consequences of that could be severe. I spent some time a couple of years back in South Georgia, which had become entirely covered by rats, which came ashore from whaling ships in 19th and 20th centuries, and also, incidentally, by reindeer. Only by eradicating the rats and the reindeer, which was an enormously expensive and complicated job, has South Georgia managed to more or less return to its pristine, original condition. We would not want that to happen on the Antarctic continent, which at the moment it is more or less pristine; there are signs of some cross-contamination, but by and large the continent is the pure wilderness that it always was. We must make sure that the increase in tourism, and perhaps in fishing and other activities, does not in any shape, size or form contaminate that.

International agreements, such as that to be discussed in Glasgow later this year, could learn an awful lot from the way in which the Antarctic treaty system, CCAMLR and the protocol have worked over the years. They have been a huge success in environmental terms, and we could learn some lessons from that with regard to the future of the global climate.

Britain has truly led the world in terms of science and diplomacy, and we should be proud of that, but there is an awful lot more to be done. We have championed marine protected areas around the world. In particular, in a miracle of international diplomacy, last year we had the Ross sea, just off the continent, designated as an MPA, which was superb. The Weddell sea is the biggest sea down there and an absolutely fantastic bit of ocean, but the ice is retreating on it. We are desperately trying to get it recognised as an MPA, but we are being thwarted by the Russians and Chinese, both of whom see the potential for commercially fishing it. We must overcome that. We must preserve the rich biodiversity and mammal life in the Southern ocean and, to some lesser degree, the Antarctic ocean as well.

With climate change and the growth in fishing and tourism, the treaty system needs to redouble its efforts on biosecurity in Antarctica and avoid the worst consequences that we have seen in South Georgia. The treaty parties must remain vigilant and ensure that the co-operation of the past 60 years continues and endures into the future.

It was for that reason that, as I mentioned, we took the opportunity last December of calling together Parliaments—parliamentarians—from all the Antarctic treaty countries. Eighteen countries came, and those were the leaders; we hope that when the event occurs again in two years’ time, there will be more than that. We think that Parliaments have an extremely important role in preserving the Antarctic continent and doing all the things that we have talked about with regard to peace and diplomacy and science. Governments tend to suffer from inertia or perhaps even self-interest. That is reasonable enough: the Government’s job is to look after their country. Parliamentarians are answerable to their electorate and have a very important role to play in holding their Government to account and making them do things that the Government would not necessarily otherwise want to do. It is popular pressure, after all, that has accelerated the drive towards combating climate change. There is so much more that we as parliamentarians can do here by talking about Antarctica and, incidentally, about the Arctic and encouraging the Government to do the right thing, which they might not otherwise do.

That is why we created the assembly last year. It was enormously successful. We had briefings from international scientists, tourism experts and policy makers about the work of the treaty and the challenges ahead. That was the first day. On the second day, we produced a statement, which I think will be looked back on as an important statement in the history of Antarctica. It was outspokenly robust. This was not a committee producing—what is that saying about a camel being a horse designed by a committee? It was not one of those. It was actually an extremely robust, clearly worded and sensible statement, and I hope that it will be an important beacon in the years that lie ahead.

We agreed that it would be a biannual assembly. The Arctic parliamentarians already do this every two years, so we agreed on a biannual assembly, the second one, in two years’ time, being in the southern hemisphere and probably—we hope—in Australia. We it will be a much bigger organisation than it was this time round, although that was a good start for what we hope will become a very long-term and important organisation.

Britain has led the world in the 200 years since the first sighting of Antarctica—it was 200 years ago today or thereabouts—and in the 60 years since the signing of the treaty. We have led the world in exploration, and I pay tribute to the great British explorers, who have done fantastic work over the years. We have led the world in scientific research, particularly from, but not limited to, the British Antarctic Survey. And we led the world in diplomatic negotiations leading to the establishment of the continent as a haven for peace and nature and scientific research. It is terribly important that we now, in a similar way, lead the world in seeking a solution to climate change, without which the future for Antarctica and for all of us looks pretty bleak. We here in the UK have pledged to uphold the Antarctic treaty and to continue to invest heavily in Antarctic research. In COP26 and elsewhere, we must now pledge ourselves to strain every sinew to combat climate change.

This week is the 200th anniversary of the first sighting of the great white continent by Bellingshausen, or perhaps by Bransfield. If we do not combat climate change and its consequences, our descendants will not live to celebrate the 400th anniversary.
