Scientific Advice (Emergencies)

Debate between Lord Maude of Horsham and Andrew Miller

Thursday 15th September 2011 Westminster Hall

[Mr Maude]

My hon. Friend is right, and in the end we have to make a judgment and try to prepare in a proportionate way based on the best evidence available, while acknowledging that that evidence will not always be conclusive. The process set in place through SAGE will try to distil the best view, which is important.

A number of Members have raised points about the communication of risk, which is an important issue and difficult to get right. When communicating risk to the public, it is important not to scaremonger, make people agitated or cause them to behave in a way that is not reasonable. Nor should we devote resources to something in a way that cannot be justified. At the same time, we must never be complacent.

I have thought about the concerns raised in the report and by hon. Members during the debate about the concept of the reasonable worst case. It is difficult to get the form of words right. If the word “reasonable” is inserted, it sounds as if it is a situation that we think will happen. In fact, “reasonable worst case” is not what we believe likely to happen; it is the worst case possible if we remove situations that are absurdly improbable. Pitching that statement correctly is quite difficult.

A number of hon. Members mentioned the Blackett review that will be published in the next few weeks, which we will obviously consider. The Blackett panel looked at the concept of reasonable worst case, which it believes—as do the Government—that it is essential to consider when planning and building capability. It believes, however, that we must think about the use of that concept in communicating risk because it may be that the concept of the most likely case is more useful.

Governments will always be anxious about having a figure in their possession that they have not shared. That was the case with swine flu, and I understand the concern of the Health Secretary at that time. The Government did not want to suppress a figure that might have been arrived at properly, even though it proved to be way off beam. These difficult issues need to be tackled in a serious and measured way and it would be useful to have further discussion and debate once the Blackett panel has completed its review. We must get this issue right because, when emergencies happen—as they will—it is important to have some kind of shared understanding across the political spectrum, and between the Government, Parliament and the media, about the way the concepts in question have been used and the need for responsibility when dealing with facts and estimations.

My hon. Friend the Member for Croydon Central (Gavin Barwell), who could not stay for the end of the debate because he had to be elsewhere, talked about the figures changing in the course of the swine flu epidemic. The truth is that in an emerging epidemic, there are very few cases on which scientists can make assessments; there is very little epidemiology to go on. Arguably, it is better to be honest about the possible worst case and plan for the worst; and then if events turn out very differently, at least that is better than their turning out much worse than predicted. I was asked whether we had used the reasonable worst case approach for the Fukushima event. The answer is yes, that did happen.

On the difficult issues about trying to get right the communication of risk, I am grateful for the Select Committee’s insights. The Blackett panel will produce its conclusions in due course, and we will share them and continue to have discussions and debates.

I was asked what progress had been made in response to the concerns that the Select Committee raised, which I understand, about the role of the Government chief scientific adviser in national risk assessment. Work is under way to set up an independent scientific advice group for the NRA, which will be in place in time for the 2012 NRA. The draft 2011 NRA has been sent to the Government chief scientific adviser, and he will respond to me and my officials in due course. Obviously, it is important that that assessment has the benefit of his detailed scrutiny. We are taking the conclusions and recommendations in the Committee’s report seriously and acting on them.

The Chair of the Committee, the hon. Member for Ellesmere Port and Neston (Andrew Miller), asked when SAGE guidance would be published. We are aiming for later this year. We are building in steps that are being taken in the light of the inquiry and the reflections in this debate.

I was asked about transparency. We agree that SAGE should operate on the principle of openness and transparency. The membership, minutes and key scientific advice papers for all three recent SAGE activations, which were in relation to the Japanese nuclear event in and around Fukushima, the volcanic ash eruption and the swine flu epidemic, have all now been published online. Everything is being taken forward, I hope, in the right spirit.

My hon. Friend the Member for South Basildon and East Thurrock (Stephen Metcalfe) asked about international collaboration. We work closely with international organisations—the European Union, the UN and so on—and with global leaders in this field. For example, the Singapore Government are a serious leader in this area, and we work with them. We also work with other countries with which we share risks. For example, we work closely with the Netherlands on the risks associated with North sea flooding. There is also ad hoc joint work and research on community resilience and behavioural issues. We work on that with the United States, Canada and the Australians. International collaboration is therefore very important. There is a huge amount of expertise, and it is in the interests of all countries that we benefit from one another’s knowledge, expertise and assessments.

I was asked about volcanic eruption as a risk. I assure hon. Members that the possibility of volcanic eruption is certainly not being omitted from the 2011 NRA. There are two risks in the risk assessment, one of which is a severe, gas-rich volcanic eruption that could reach toxic levels at both ground level and flight altitude. Obviously, that is less likely to occur but would have very significant impacts. We acknowledge that the volcanologists are saying that the likelihood of further volcanic eruptions is higher. We are obviously taking that into account. There is a higher likelihood of a much less severe volcanic ash-rich eruption. A great deal of knowledge was gained from the experience of the eruption last year, and a lot of action has been taken on the back of that.

[Andrew Miller]

Before the Minister moves on, I am curious to know how information held in other Departments is brought in. Obviously, there is a significant role in some Departments through the Civil Aviation Authority and so on, but the Ministry of Defence also has enormous expertise. Years ago, I was in the Caribbean with the Royal Navy when the volcano on Montserrat blew. The helicopter pilot at that time said to me, “Mr Miller, you can’t get any closer to take photographs because these things fall out of the sky if they get the slightest bit of dust in their engines.” There is a huge amount of information that is very old, but that we have failed to centralise. What is the right hon. Gentleman doing to shake up other parts of the machinery to get all that information together?

[Mr Maude]

That is a very good question. Are Government always perfect at ensuring that all the information and knowledge is harvested and garnered from all parts of Whitehall and well beyond, including all the agencies and organisations? No, not by any means. A big part of the role of my officials in the civil contingencies secretariat is to try to ensure that we bring that body of knowledge together as best we can. One would hope that in an event like the volcanic ash eruption, the Ministry of Defence would be intimately involved—I am sure that it was—in assessments and decision making. However, it is a perfectly good question. It will not always be perfectly answered, but we are conscious of the need to maximise the bringing together of all the knowledge on this front.

My hon. Friend the Member for South Basildon and East Thurrock and others talked about space weather. That is potentially a big hazard with really serious impacts. We need to deal with it in a thorough way. The truth is that more work is needed to understand what the wide range of impacts would be from a serious event. The Department of Energy and Climate Change is engaged with National Grid, the energy emergencies executive committee and the British Geological Survey to consider the implications of a severe space weather event for the electricity system as a whole, including the potential impacts on generator transformers and further consideration of the transmission network. We in the Cabinet Office will continue to work with other sectors that could be impacted to develop a more comprehensive understanding of the vulnerability. Work on that issue continues.

The only other time when there was a major event was in 1859—the Carrington event, which has been mentioned. That was a very different world. There have been other events, but they tend to be localised. The likelihood of such an event is therefore not high, but it is real and we need to address it in the best way we can.

My hon. Friend the Member for South Basildon and East Thurrock asked whether we were participating in the European Space Agency’s space situational awareness programme, which runs until 2012. We have subscribed to it. It defines the steps that need to be taken on space surveillance and space weather. The UK Space Agency will engage with the potential space weather user community and data service providers to assess the relative priority of funding space weather activities within the ESA space situational awareness programme. That will obviously need to be reconciled with competing demands for other programme opportunities and existing financial commitments, but no clear conclusion has yet been reached. However, we are very aware of the risk, and a great deal of work is going on in relation to it.

I turn to the question of cyber security, which is obviously a serious matter. It was identified in the strategic defence and security review as a high risk, and a significant budget has been attached to the national cyber security programme; as Minister responsible for the Office of Cyber Security and Information Assurance, I have oversight of that programme. Our approach is to ensure that we invest in building capability, as capability is relatively scarce. We have an affordable centre of excellence and expertise at GCHQ.

This is a question not only for the Government but for the whole economy. We discern a marked range in the degree of preparedness of private sector companies on cyber security. Some are highly developed, but it is not only companies focused on internet activities that are vulnerable; it goes much more widely than that. Some companies that ought to be concerned about cyber security do not take it as seriously as they should. Over the coming months, we will be encouraging them to address it seriously. It should be on the agenda of every risk and audit committee, to ensure that it is properly understood and dealt with.

In a few weeks’ time, I shall be publishing the Government’s cyber-security strategy and I hope that it will receive attention and be debated by the House. These are most important matters, and we must do our best to get them right.

[Andrew Miller]

I am fairly confident, following Sir Edmund Burton’s report on the missing Royal Navy laptop, that part of the Government’s response will be about awareness and the training of personnel. Will the Minister confirm that that will happen throughout the civil service machinery? It is no good saying that it belongs only to permanent secretaries or techies in the back room, because it affects us all. There has to be a serious campaign in the public sector to ensure that people understand how serious these challenges are.

[Mr Maude]

The hon. Gentleman is right, and I do not dissent for a second. Most of it is about being reasonably alert and aware, and taking common sense steps, but higher levels of vulnerability to cyber attack and cyber crime require a highly sophisticated response coupled with great awareness and agility. Information assurance and not allowing data to go amiss are mostly to do with basic standards of care and alertness.

I am grateful to have had the opportunity to respond to the Committee’s thoughtful and serious report. It has been good to ventilate these matters. I assure the House and the Committee that we continue to take these matters seriously. We will continue to engage and interact with the Committee as we take these matters forward.
