why not just nuke the poles in the dead of winter for each. it could bust them up send them out farther into the ocean causing the capes to increase in size. with the bonus of fallout cause harsher winter storms on each pole locking away the radiation. the cooler oceans will ensure that ocean life will continue to make our way of life possible. the input cost would also be so minimal. this is a temporary we would still need green energy to slow CO2 pollution. also we might wipe out polar bears.
