A UK government release dated 21 October 2026 reported that a new Climate and Nature Security Taskforce, described as the world's first of its kind, had met for the first time that week. Chaired by Climate Transition Minister Katie White alongside Baroness Fiona Twycross, it was to make independent recommendations on national and international climate security challenges, including assessing risks and the UK's readiness.

Members listed in the release included General Richard Nugee, International Crisis Group president Comfort Ero, National Trust science director Rosie Hails and Erin Sikorsky of the Center for Climate and Security. The release said the group was to identify the most significant climate- and nature-related security risks and define objectives covering evidence-based policy priorities, review of government work and international focus. It followed what the release called the UK's hottest summer on record and a year of heatwaves, drought, wildfires and flood risk.

The terms of reference stated up to two meetings in 2026, one in person and one virtual, with an assessment of gaps in the government response and recommendations for further work.
