Cabinet Office

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.
