Sea level rise is a very slow process if one thinks in terms of days, months or even years. Thus, what should be done at locations where sea level rises, is mostly to be prepared for the consequences of sea level rise. Adaptation is the most important action to be taken in order to minimize any type of loss in the future.
Other than adaptation, measures to mitigate global warming and climate change should be integrated to present national policies and our ways of living. There are several awareness raising projects trying to inform public on the measures to be taken to lower the greenhouse gas emissions such as switching to alternative energy resources other than fossil fuels, insulating our houses to decrease the excess use of energy, walking rather than using cars, etc.
