Such efforts would also tend to mitigate some of the ice melt, since the remaining iceberg mass would end up on land. Does anyone know what happened to those efforts?
I remember a few years back a lone iceberg floated within helicopter range from Antarctic toward Australia. In fact the helicopter landed on it and took some news footage. I can't find reference to it now but I remember it started the whole iceberg towing thing off again.
Anyhow it was discovered that it is not quite as practical as once thought. Ocean drag and currents were a contributing factor but the wind sail area was the killer and the thing that overpowered the currents and pushed it closer to us.
I guess if you picked the right iceberg at the right time and place it would be possible but its not a simple as it sounds.
