Former military leaders rightly point out that climate change is a matter of national security (UK must consider food and climate part of national security, say top ex-military figures, 29 May). What is required in response is a thoughtful, strategic approach that focuses in on actions that are practical and effective in these difficult times and will help build the UK government’s “strong foundations” of national security and secure borders.
For example, arguably the biggest near-term threat to UK security is the “mass population displacement” that Lt Gen Richard Nugee refers to. About 3.5 billion people live in an arc around Europe, across Africa, the Middle East and Asian countries such as Pakistan, India and Bangladesh. People in these regions are already confronting floods and heatwaves of up to 50C that are making large areas uninhabitable. Rural communities are being forced into conflict and migration, while food production and supplies to cities are being affected.
