This document summarizes a symposium discussing how indigenous peoples are affected by and responding to climate change. It describes how indigenous peoples' livelihoods depend directly on natural resources impacted by climate change. While often viewed as helpless victims, indigenous peoples are actively adapting to changes through traditional knowledge and new technologies. The document then examines climate change impacts and challenges for indigenous peoples in different environments, such as rising temperatures threatening Arctic livelihoods and languages, alpine species migrating up mountains, expanding deserts reducing grazing land, droughts endangering rainforests, and rising seas threatening island communities.
