I am grateful for my hon. Friend’s intervention. Yes, I have had such discussions, and I was quite surprised to find out just how far some other countries have gone. The Netherlands provides a good example. It is already further on than we are in taking legislative action on Antarctica. I met a Netherlands member of Parliament during the climate change conference in Doha, and I was impressed with the level of legislative detail the country had gone into in respect of Antarctica. I have talked, too, to representatives of Chile and noted their interest in carrying out a similar policy. I am pleased to have an opportunity to confirm that there is a memorandum of understanding between Chile and the UK on Antarctica matters. That paves the way for more international co-operation and demonstrates that nation states are taking the issue seriously.

We were also told about long-term record keeping of weather conditions, temperatures and so forth. That is important because we cannot just take a snapshot now and make a judgment; we need to go back some years. The British Antarctic Survey has been working on climate change, looking for patterns and studying changes for nearly 20 years. That knowledge base is important and it is used by others as a benchmark for measuring developments in climate change.

My hon. Friend is speaking interestingly about the work of the British Antarctic Survey. Did he get the opportunity to see some of the work that it has been doing on ice cores to measure the historical carbon dioxide content in our atmosphere, which is hugely important in global warming and climate change?

Is my hon. Friend aware that Plymouth was Captain Scott’s home town? The Plymouth marine laboratories have done an enormous amount of research on climate change, and there is a great tradition in Plymouth of ensuring that that continues to happen.

I touched on the foreign policy aspect of the legislation when I mentioned Chile and Argentina. It is important to note that other nation states are becoming interested in Antarctica. Just 12 nation states signed the treaty in 1959, but now the number expressing an interest in Antarctica exceeds 50. Unlike us, however, some of those nation states do not have aims and objectives consistent with a determination to protect the environment. We should be using our influence to ensure, first, that all nation states respect the idea that Antarctica should remain properly protected and not be exploited, and secondly that it remains demilitarised. It is important to state and restate both those points, because we have to remember that Antarctica is pristine, vulnerable, pivotal to our climate change issues and has no Government. It relies on interested nation states coming to an agreement, including on territorial claims, about which we have heard in the past few weeks and whose contest the treaty suspends. We should take note of that.

During my visit, I learnt that—as my hon. Friend the Member for Stroud said earlier—the BAS had drilled 800,000 years into the ice, taken out that ice, and was analysing what had happened to the climate over those 800,000 years. It is still conducting that analysis. I even had an opportunity to touch some of the ice, which made me feel that I had touched 800,000 years’ worth of our climate. That work has had a major impact on the whole climate change story, which I find incredibly interesting. It convinced me that things are indeed happening to our atmosphere which are having significant effects.

The BAS concluded that for the vast majority of those 800,000 years there had not been much climate change, although there might have been some global warming, mainly owing to slight tilts in the earth’s axis. However, it also found that during the 300 years since industrialisation began, there had been a significant amount of acidification of the atmosphere, which had produced much of the climate change. Acidification produces rain, which falls on to the earth or into the sea, where it is having a major impact on our fishing stocks. There are signs that some of the plankton and krill on which fish feed are moving. The Bill is important because it seeks to ensure that we are much more environmentally friendly, and I hope that the Foreign Office and the British in general will be taking the lead in that.

We remain fully committed to the treaty, seeing it as one of the best conflict prevention strategies, as well as a robust protection for our sovereign claim to the British Antarctic Territory. The Government want to ensure that the treaty system does not stagnate, and it is crucial that the treaty parties continuously look ahead and make sound, proactive decisions about future management. Co-operation has worked in the past and we hope it will continue to do so. With an increase in the number of parties engaged, it is not only dependent on the commitment of states to the treaty system, but intrinsically linked to wider global challenges, from population increases to global climate change impacts, wider diplomatic relations and the continued willingness of states to work together for the greater good.
