“ if one could determine the total surface area of the worlds oceans.”
You cant use the surface area only to calculate it. Raising the ocean level changes the surface area itself
True, factorially true... and that increase in itself would be a danged complex calculation, thinking out loud. One farm pond... if its edges are not “overrun” with a vertical quantity of rain— say a pond that has a 12 inch above highest waterline concrete straight up wall. But to over run sandy (absorbent and not) shores all over the world. Esta non possible’.
And then that irritating concept of the worldwide daily and nightly evaporation of surface water into the atmosphere (water vapor being the MOST important factor in climate warming... not CO2). So there’s that as far as “rise in the ocean levels”. All of these factors are precisely why the entire concept of this looney prediction is not readily provable, nor possible to link it with.... warming, and melting... as in, why not re-freezing even if you say it is warming? This is fun.
