The US state of Alaska and dozens of native villages along its coast are on the front lines of climate change.

Every year, more and more land is lost to the rising sea as the permafrost deep beneath melts with rising temperatures.

The loss of land is forcing communities into a difficult situation - to stay or move - and if they move, to where?

Moving an entire village is a costly operation and no one is quite sure where they will get that money from. Can culture and traditions be maintained if communities move somewhere else?

Fault Lines travels to Alaska to see how communities there are coping with climate change.
