Second Sea

Second Sea is an online interactive platform that projects the loss and damage facing coastal cities as a result of rising sea levels and human-induced climate change. Its launch coincided with COP27. Through a bespoke algorithm, Second Sea assigns a share of future loss and damage faced by coastal cities, which is calculated according to the cumulative historical CO2 contribution of each nation, up to the present. It generates a nationally itemised invoice, which shows the proportion of cost owed by each nation to the coastal city in question if CO2 contributions continue in their current trajectory.
