I have a thought about ice cap melting: would it be possible to dredge a deep enough hole in the ocean to accommodate all the melted water so that the land above the water would not disappear ??

TG is right. Imagine the energy required to dredge such a hole. It would pump more CO2 into the atmosphere, raising the temperature higher yet.
An easier way to dredge a hole would be to redirect some asteroid into a collision course with earth. Still, you would have trouble making a crater big enough to hold the water displaced from Greenland and Antarctica. (The arctic ice cap floats--so when it melts it won't contribute much to rising ocean levels).

No. The amount of material would be staggering. You will see, however, many local projects where material is dredged from the sea floor to build protective walls and dikes around endangered cities and other areas.
