islands on the frontline

Island states are at the forefront of climate change. Rising sea levels mean more coastal erosion, overtopping of defences and salinification of land. From atolls in the Pacific Ocean to the coast of Northern Ireland, we find out how technology such as lidar is helping island nations become more resilient and adapt to the effects of climate change. We learn that Geo-data is critical for accurately mapping and predicting the impacts of rising global temperatures, and for protecting traditions and ways of life for generations to come.
