Reclamation of Sea by way of sand & cement fill will also raise sea level.

The forming and thawing of ice and thereafter the evaporation of water which would bring rain on earth is a cyclical process... while the landfill is a permanent process.

A lot of countries are buildiing "into the sea"... by this act they are flooding the low lying countries in some other part of the Earth.

The act is equal to invasion of that country!
