Making changes to lessen the impact of flooding. This can include things like building sea walls, building storm-surge barriers, re-instating mangrove forests
Mitigation
Making efforts to reduce the emission of greenhouse gases and so reduce the impacts of climate change
Statistics
IPCC predicted by 2100, hundreds of millions will be forced out of their house due to rising sea levels
Storm surges will also rise (Hurricane Sandy 2012, $65bn damage)
It is uncertain because of the unpredictability of the future
Climate change; warmer seas; more tropical storms and ice melting
IPCC say that a 2 degree temp rise will result in a 1m sea level rise
