Can seawater desalination plants in coastal areas...

help reduce the dangers of sea level rise in future? Or the water table will find its way back again into the oceans?

How will it help?
Sea water rising is caused due to melting ice - desalination plants being energy intensive will add to the greenhouse gas emissions, thereby accelerating the rise.

I don't see what one has to do with the other.
Even if it has anything to do with the other, assuming even a 1mm rise in the water level of the sea - I cannot think of ANY desalination plant that can absorb this 1mm rise.
Even if any desalination plant can do this, where does the output of the desalination go? And then after that where does it go?

Lets say 100 million litres a day by about 20 desalination plants in coastal areas in each coastal country can be stored in lakes reservoirs and aquifers powered by solar or wind energy catering to human consumption. By prodicts like salts too may be useful. The mighty oceans can be constantly drained by a few drops figuratively speaking. Scientists are working on this idea google says but is not conclusive as what progress they have made so far. Some say water cycle will not change though but logically it sounds like there is some hope.

Given where we are tech wise, I don't think it's realistically possible given the extremely high energy requirements for desalination, but we can but hope that someday we get to it.
