Extreme events in the Arctic, like the devastating 2017 Arctic tsunami in Greenland, are on the rise due to climate change. These events are reshaping the landscape, endangering ecosystems, and threatening Indigenous communities. As permafrost thaws and glaciers melt, the stability of rocky coastlines diminishes, leading to more frequent and severe disasters. Scientists and Indigenous peoples are working together to monitor and adapt to these changes, but the challenges continue to grow as the Arctic warms.
