I wasnt going to subject you guys to my planet saving ideas but you opened the door
For many years, it has been known that warm water is less bouyant than cold water. This is why ships have not one, but several, lines painted on their hulls. These are load-level markings for different water conditions. Basically, for any given loading, a ship will sink deeper in tropical waters than it will in winter Antarctic conditions, and there can be a considerable difference in the amount of water displaced.
Of course, there are a lot of supertankers out there sitting low in the water. If you think about it, when a supertanker sits low in the water, that means its pushing the worlds oceans up a bit.
If supertankers didn't sit so low in the water, they wouldn't displace so much water and if less water were displaced coastal water levels would go down a bit. Once that is understood, the solution becomes obvious. Just throw a grapling line around the icebergs floating around Antarctica and tow them north.
Its a win-win scenario, as some politicians would probaly say. They would cool the tropical waters, the supertankers would float higher and coastal water levels will go down.
I'm surprised no one has already thought of it.
