UK Names Dame Madeleine Alessandri as Its First Climate Security Envoy

The United Kingdom has appointed Dame Madeleine Alessandri as its first special representative for climate security, Prime Minister Andy Burnham announced at the COP31 climate summit in Antalya on Nov. 12. The role formalizes the government’s view that climate-related disruption can also create national security risks.

Burnham announced the appointment in a speech describing climate change as a security issue. The Associated Press reported that a British government assessment earlier this year warned that ecosystem damage could disrupt food supplies and intensify conflict and migration. The UK imports about 40% of its food, according to the AP report.

What the new appointment signals

The government has not yet published a detailed public remit for the representative in the announcement. Burnham’s speech places the post within a broader effort to connect climate resilience with security planning and international policy. Its practical scope will depend on how the role is defined and used across government.

Alessandri brings a national security background to the post. Her official biography lists previous roles as chair of the Joint Intelligence Committee, permanent secretary at the Northern Ireland Office and deputy national security adviser. The appointment therefore puts climate-related risks alongside issues already handled through the UK’s security and intelligence system.

Why climate risks are framed as security concerns

Climate impacts can affect security indirectly as well as through extreme weather. Disruption to food production or supply chains, pressure on infrastructure, and damage to livelihoods can compound existing vulnerabilities. The UK assessment described by the AP focused on risks to food supplies, conflict and migration; it did not mean that climate change alone causes any one conflict or movement of people.

The appointment was announced during COP31, where governments are negotiating climate action and finance. The Globuzz previously outlined the summit’s agenda and the risks facing vulnerable countries. Whether the new envoy changes policy will become clearer as the government sets out the post’s responsibilities and follow-up work.
