Just fasten a geotextile belt around the iceberg (video), deploy a geotextile skirt to prevent melting, then tow that puppy thousands of miles using “bumps and holes”in the ocean to help out because a tug can’t possible handle the load.
Golly, what could possibly go wrong with this?
Well. some grumps in the comments opine that when icebergs melt then can flip over which could be a bit inconvenient. Plus, tugs in Arctic sometimes try to tow very small icebergs out of the way and end up getting towed by the iceberg. (sort of like a Nantucket sleighride!)
And do you think countries will stand by and let their icebergs be kidnapped by interlopers from elsewhere. I think not.
