$2\mathrm{.}1.$ Use Figure $2\mathrm{.}24$ to estimate low$-$range and high$-$range projected rates of sea level rise $(m\frac{m}{y}r)$ in the year $2100,$ assuming the rate of increase will continue at the same rate in the period $1870($when the instrumental record started$)-1930.$ Convert these rates to inches per year.
