Model suggest that in 2010 is above 6.4k and the diffusivity of water is 1.24108 How will the sea level rise?

Model suggest that in 2010 is above 6.4k and the diffusivity of water is 1.24×10−8

How will the sea level rise?

(b)Using the (finite difference) approximation to the heat diffusion equation, estimate how much time would be required for this heat to diffuse to the average bottom depth of the oceans.

(c)How does this timescale compare to the time required for the oceans to mix?
