Cabinet Office

Sammy Wilson Excerpts

Monday 29th June 2026 Commons Chamber

[Dr Ellie Chowns (North Herefordshire) (Green)]

I thank the hon. Member for Warwick and Leamington (Matt Western) for introducing the debate so well. He makes many excellent points, including that we face a wide range of threats to our security and resilience. Clearly, we face threats from hostile actors and not just through conventional means: he talked about cyber-warfare and the threat of disinformation. He briefly touched on the effects of the pandemic on our country. The covid pandemic, which killed nearly a quarter of a million people, was the greatest threat to human health for many decades. Recognising pandemic preparedness as hugely important within the security and resilience framework is key.

Another key threat to our country’s security and resilience, which does not receive nearly enough attention, is climate breakdown. It is not just the environmentalists but the ambulance workers who say that, and the Joint Intelligence and Security Committee’s national security assessment itself says that ecosystem breakdown poses a clear threat to national security. The Committee on Climate Change has pointed out that we are woefully ill-prepared as a country for the effects of climate breakdown.

We urgently need to take more action to avoid causing climate change. Equally, we urgently need to take far more action to recognise the threat to our national security and resilience posed by the effects of climate breakdown. That was brought home to us in hugely clear terms last week, as we faced the second major heatwave of the last month or so. That heatwave led to record call-outs for the ambulance service—even more than under covid.

A couple of weeks ago, I spent time with the London ambulance service, which told me that the May heatwave saw its highest number of ambulance call-outs, even including covid, and that terrible record was exceeded last week. We have to recognise the reality of the effects on human life and livelihoods and the effects on our national security and resilience caused by these issues.

This is not just about the health effects. I spoke to numerous constituents over the weekend about the effects that the appalling temperatures faced by our students are having on schools. Clearly, we need urgently to put in place maximum temperatures for schools and workplaces and take action to ensure that that is followed through.

[Sammy Wilson (East Antrim) (DUP)]

Does the hon. Member accept that there is a certain irony when the same people who are concerned about climate change and temperatures rising have campaigned for air conditioning to be taken out of buildings because of its energy consumption and carbon dioxide emissions? We cannot have it both ways, can we?

[Dr Chowns]

I honestly do not recognise the caricature that the right hon. Gentleman paints. Technology exists to provide both heating and cooling in ecologically friendly ways, and that is absolutely what we need going forward. We need far better building standards so that we build buildings that adapt and are suitable, and we need homes that are fit for the future. That is essential.

The Committee on Climate Change—the Government’s independent adviser—has set out repeatedly that these solutions are available and has set out the things that we need to put forward. The Committee has also set out repeatedly, as have any number of people over any number of years, the fact that the costs of inaction far exceed those of action. The hon. Member for Warwick and Leamington (Matt Western) made that point previously in relation to other security challenges, and it applies with knobs on to tackling the challenge of climate breakdown. Twenty years ago, Professor Nick Stern set out clearly that the costs of inaction far outweigh—many times over—the costs of action to address these risks. After 20 years of our heads collectively being in the sand as a country, we are reaping the whirlwind of that inaction.

I call on the Government and the Cabinet Office to recognise the reality that tackling climate resilience must be a central plank of any strategy to protect national security and resilience. We need a Minister in the Cabinet Office whose responsibility it is to put in place that work and to take a cross-Government approach. This is not a siloed issue and cannot be dealt with in one single Department; it needs a cross-Government approach.

We need a comprehensive strategy to prepare the NHS for new public health challenges. We need to invest in flood protection, because we face not just extreme heat but flooding incidents of increasing frequency and severity. We have all seen what a disastrous effect that has on the economy as well as on lives and livelihoods.

We need to develop a comprehensive extreme heat strategy, a national drought plan and a farmer-led transition to climate-resilient food production. Our farmers are crying out for that support, and they too are on the frontline of the security and resilience challenges that the reality of climate breakdown places on us. We need to strengthen our transport infrastructure, energy infrastructure and water infrastructure. Last week, we heard about nuclear power stations going offline in France. Train companies were saying that nobody should travel unless it was a matter of life and death. Water shortages are becoming more and more frequent. The collective, long-term and strategic approach to tackling climate resilience must be a core plank of national security.

Tackling climate breakdown is not just an environmental issue but a central plank of security and national resilience. The costs of inaction far outweigh the costs of taking action now. Will the Minister commit to putting in place a national strategy? Will there be an individual identified in the Cabinet Office who leads on it? Does she recognise that we must invest now or pay far worse costs later?
