River and sea level rise
Giving up coastline and looking up, that's a plan B at sea level rise
Sea levels are rising rapidly; ice loss in Greenland and Antarctica is increasing, and satellites measure an acceleration of global sea level rise. The rate of that increase in the 20th century was below 2 millimeters per year, after the year 2000 it was around 3 millimeters and in recent years it has risen to 4.3 millimeters per year. How much that gear will continue is uncertain.
For international measures to combat climate change and sea level rise, consider the option to leave coastal areas. Start with that now, although it may take decades for these areas to be swallowed by the sea. “It's a tricky message. But if you start it on time, it can be an attractive option”, says Marjolijn Haasnoot, researcher at Deltares knowledge institute and lead author of one of the articles.
Sea level rise expectations vary widely: from 30 centimeters to 1 metre in the next 100 years
Dealing with this embedded uncertainty is the main challenge that engineers, landscape architects and policy makers face. Which solutions are so agile that they can be applied to all possible scenarios??
