International dimensions within national assessments
The UK and Canada recently published national assessments of climate change, and both reports include a chapter on international dimensions.
The Third UK Climate Change Risk Assessment Technical Report shows that the urgency of action for some of the risks associated with the international dimensions of climate change is greater than previously assessed. These risks include food security, violent conflict, international law and governance, and public health.
The Canadian National Issues Report, which contributes to the national knowledge assessment process ‘Canada in a Changing Climate: Advancing our Knowledge for Action’, focuses on Arctic shipping, transboundary resource management, international trade, and climate-related human migration and displacement. It concludes that it is challenging to assess the significance of excluding these transboundary, teleconnected or cascading effects in measuring Canada’s progress in adapting to climate change.
