Two dynamic and engaging virtual debates for mayors will be organised in April and June. Mayors will debate how to move forward both in their own communities, to protect their citizens from the threats of climate change, and together, as a governance body, to build up a coalition of mayors and communities to make real change. In October, Mayors will deliver a Call to Action, a uniting front to accelerate action on climate-related migration by promoting, guiding, monitoring and sharing experience on climate resilience amongst mayors. City networks and international organisations will be invited to join the debate and support the Call to Action. This Mayors Call to Action will be an integral framework, bringing together mayors to present their plans and push for climate-resilient action at COP-26 that will take place from 1-12 November 2021 in Glasgow (UK).
