Plus remember. The crust of the Earth is flexible and not completely rigid. Water is very heavy and pushes down on the crust. Making the crust rise elsewhere. So all these calculations need to factor that in. If you melt ice from above sea level and add water to the sea. Then you also increase the weight bearing down on the crust.
>Then you also increase the weight bearing down on the crust.
Then you also increase the weight of the sea bearing down on the crust. While at the same time removing weight from whatever land mass the ice formerly occupied.
fixed it, sort of
