The world today faces probably the greatest challenge it has faced for thousands of years. Unless we do something about it—something dramatic and urgent—we face environmental catastrophe not only in the Antarctic, but across the globe. That applies especially, but not only, to climate change.

Antarctica is living proof of what we are currently facing with regard to climate change. We must do something about Antarctica, and by doing something about it we can also help the rest of the globe. By focusing on every aspect of life on the great white continent and its governance, I hope that this debate will help environmental considerations elsewhere.

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.

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.

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.

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.

As has been said, 2020 is a historic year because we are marking the 200th anniversary of the first sighting of Antarctica by the Royal Navy Captain Edward Bransfield in 1820. In the 200 years since, Antarctica has had a very special place in people’s minds, but it has never been at greater risk than it is now—from two things: intrusive foreign powers and climate change.

The second issue is climate change.

It seems ironic that it is the fossil fuels and the possibility of finding them that make Antarctica alluring to foreign powers but are also the thing that is causing its demise. I was interested to read a BBC report from Justin Rowlatt today. He had a very exciting visit, by the sound of it, to Antarctica and has talked about the challenges that he faced just in getting to the ice sheet and being able to stay there and see what was happening, because of the storms. The report describes the east Antarctic ice sheet as being on land and about a mile thick, being relatively stable and not really sinking into the sea, and being relatively unchanged, but it describes the west of Antarctica as being ice largely floating rather than on land. That is a smaller proportion of Antarctica—only 20%—but it is much more vulnerable to the effects of climate change, of global warming, and therefore to melting into the sea.

I congratulate the Government on what they have done to protect those bits of the marine environment that they can down near the south of the world, particularly in the 4 million sq km of marine protected area, including around South Georgia and the South Sandwich Islands. That was described by my hon. Friend earlier, but I will stress again what he said. We need to have the Weddell sea as a marine protected area and to work with countries around the world to make that happen. I understand that there is a little bit of resistance, but the hope is that we will be able to overcome that. We have opportunities, particularly as we host the international climate change conference this year, to bring that issue right to the fore. I am interested in what the Government are doing to try to stop the potentially irreversible depletion of ice sheets before it is too late.

Finally, I want briefly to talk about science. Much of the knowledge about climate change has been gathered by brilliant British scientists. They have made a brilliant contribution to polar and climate science. In fact, in the period from 2011 to 2015, the UK produced the second greatest number of scientific papers in relation to Antarctica. It is crucial that we inspire a new generation of polar scientists. I was pleased to hear the hon. Member for Bristol West (Thangam Debbonaire) say that her mother and her niece are engaged in this field, suggesting multi-generational interest in Antarctica. It is great that they are both women. As a Conservative party vice chairman, I am interested in how to encourage more girls to study science, technology, engineering and maths. I am interested in projects such as Homeward Bound, which took 100 women from 33 countries on a three-week expedition at the end of last year, visiting 10 bases and research stations over three weeks, with the aim of getting women interested in Antarctica, giving confidence to female scientists and inspiring younger girls to consider this field of science. That kind of programme will help to bridge the gender equality gap in science. Currently, 72% of those researching globally are men; we need to get women in there too.

As is usual in debates on the polar regions instigated by the hon. Gentleman, there has been a lot of agreement. I will address three areas: the profound challenge of climate change in the polar regions, the value of scientific research-based evidence in developing policy responses to challenges in those regions, and the existing and developing defence and security challenges in the polar regions. In his intervention about China and the Antarctic, it was interesting to hear that there is a belief that the People’s Republic of China will continue to support the treaty, and I am glad to hear that. Nevertheless, I am concerned, being an observer in the Arctic Council, that there has been some dubiety about China’s support of that council in the northern polar region, and we need to keep our eye on that.

The hon. Gentleman made some important points. The world faces its greatest challenge in trying to preserve this extraordinary area of our planet. He said that unless something is done about climate change, we will suffer hugely—a point also made by the hon. Member for Sleaford and North Hykeham (Dr Johnson). The hon. Member for North Wiltshire also spoke about the all-party parliamentary group for the polar regions, which would not exist without him. He has done remarkable things to get that group set up and ensure it has the impetus to do things and visit those regions. I congratulate him on that excellent work—long may it continue.

The hon. Member for Sleaford and North Hykeham said that the effect of climate change in Antarctica would be irreversible if we allowed the ice to continue to melt at the current rate. That would lead to an unprecedented rise in sea levels, which, as the hon. Member for North Wiltshire pointed out, could drown us here in the Palace of Westminster, never mind most of London and a lot of the United Kingdom.

15:16 The Parliamentary Under-Secretary of State for Foreign and Commonwealth Affairs (Mrs Heather Wheeler)

Scientists from British universities and other institutions use BAS vessels, aircraft and bases to understand global changes in weather, biodiversity and ocean currents. They contribute to UK Government objectives, including on climate change, energy security, global food security, innovation and economic growth. Thanks to the scientists, we now know that Antarctica drives the global ocean and atmosphere and is fundamental to understanding our planet. Antarctica is a unique place and a barometer of the global impacts of climate change. The challenges of operating there mean that international co-operation is essential.

I am most grateful to the Minister for her firm commitment to continuing the work she has described. On the question of climate change, should responsibility within the Government primarily be with the Foreign Office? I think it should be because, as she says, Antarctica is the responsibility of the Foreign Office. Alternatively, is it primarily a responsibility of the Department for Environment, Food and Rural Affairs—and which should it be?

There is even better news: the Prime Minister will chair the Cabinet Committee on Climate Change in the run-up to the conference of the parties in November, in Glasgow, and I do not think there can be a higher authority than that.

An example of international scientific co-operation is the Thwaites glacier research programme, a UK and US-led project studying the west Antarctic ice sheet, which is crucial to understanding the size and speed of sea level rise caused by the melting of the Antarctic. Colleagues may have seen reports about it on the BBC this morning. BAS scientists are also part of an international project to extract cores of ice up to 1.5 million years old. Those will help us to understand how carbon dioxide levels have varied in the past and, in turn, help to predict future changes. In the year when the UK is hosting the UN climate summit, COP26, in Glasgow, that sort of vital research can show the world that what happens in Antarctica matters to all of us. Changes observed by scientists in the polar regions show how crucial it is that we agree a new comprehensive deal in Glasgow to address climate change. That will be a tough test of international diplomacy, but we are ambitious and determined. Science shows us that we have no choice.
