Thank you for the supporting information showing that both temperatures and sea levels during the pre-industrial era have been higher than they are now.

Everything has a cycle - those swings in temperatures and sea levels over the past 20,000+ years were not due to human activity but natural processes. No trend on an astronomical scale can be stopped or reversed by humans yet. Until we consistently produce a significant fraction of the energy output of the sun, we don't come close to running the show.
