Sea level is currently rising at 3.2 mm/yr, and scientists predict that global warming could cause a rise in sea level of 7 m if left unabated. how long will it take the sea to rise 7 m at the current rate?

2188 years

Explanation:

given,                                              

see level rising at the rate = 3.2 mm/yr

height of the sea level to rise = 7 m        

time it will take rise 7 m = ?              

we know,                                      

           1 m = 1000 mm                          

           1 mm = 0.001 m                          

rate of increase of rate = 0.0032 m/year                  

time taken to rise =

                             = 2187.5 years                                    

Now, time taken by the sea level to rise 7 m is equal to 2188 years.
