We can use the formula:

time = distance / rate

In this case, the distance is 7 meters (as given in the question) and the rate is 3.3 mm/yr (given in the question in millimeters per year). We need to convert the distance to millimeters so that it matches the rate:

7 meters = 7,000,000 millimeters

Now we can plug in the values:

time = 7,000,000 / 3.3 
time = 2,121,212.12 years

So it will take approximately 2,121 years for the sea to rise 7 meters at the current rate of 3.3 mm/yr.
