A sweeping national climate assessment argues that exclusion from decision-making has amplified Indigenous vulnerability to floods, storms, and erosion.

The 2026 National Climate Change Risk Assessment is composed of four reports, including a companion document focused on Māori communities. That report argues that climate change is likely to deepen existing inequities shaped by colonization, exclusion from decision-making, and chronic underinvestment.

The assessment, released earlier this month, adds to a growing body of national reports that highlight the harmful impacts of colonial policies on Indigenous peoples and the environment. In 2023, the United States’ Fifth National Climate Assessment found that land theft and colonization had exacerbated climate change’s impact. The year before, Australia’s State of the Environment report was prepared with an Indigenous lead author for the first time; it found that Indigenous peoples were more likely to be impacted by extreme weather events like fires. It too called for incorporating Indigenous knowledge into climate policies. Despite these findings, Indigenous leaders around the world say national governments are still not listening to them.
