Sea level rise will be an issue...

I've been teaching about the slowly unfolding disaster of sea level rise and its causes since the late 1980s when I taught the glaciation and periglaciation unit for the old Cambridge 'A' Level, which focusses on the rise and fall of the oceans through the millennia.

The Guardian has a detailed explanation of the impacts of this, written by Damian Carrington.

Today, about 230 million people live within 1 metre above current sea level, and 1 billion live within 10 metres above sea level. 

Even just 20cm of sea level rise by 2050 would lead to global flood damages of at least $1tn a year for the world’s 136 largest coastal cities and huge impacts on people’s lives and livelihoods.
