Nearly four million Americans, occupying a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests.
Figure 4 - 2nd of two Environmental Research Letters SLR publications. Sea level rise storm surge flooding risk along US coast. For the ensemble average estimate of relative SLR at each gauge, projected return periods, by 2050, for floods currently qualifying as 100 yr events.
In our series comparing population growth for different sets of countries today we have a special: the new number 4, 5 and 6 of world populations – compared to the biggest decliner, set in the year 2031.
