The film is inspired by concerns about global warming, rising sea levels, and land- surface tilting. (see notes)
Notes & references:
Although ice melt from Alaska contributes to global sea level rise, sea levels near Alaska have been decreasing because the land beneath the state is rising due to shifts in the Earth’s tectonic plates and a process called glacial isostatic adjustment. Despite this, the state could see rising water in the future, as sea levels will eventually rise faster than the land. Alaska is still experiencing some of the effects of changing sea levels, like increased flooding and erosion, and some coastal villages are already relocating.

Sea level will continue to rise to 2300 under all climate change projections. The UK land surface is tilting, with Scotland rising and southern England sinking, such that greater rates of sea level rise will be experienced in the south of England.
