LONDON (Reuters) - Fleets of supertankers could one day ply the world's oceans laden not with oil but fresh water.
Sounds far-fetched?
In Paris on Friday the world's top climate scientists issued the strongest warning yet that human activity was heating the planet. They forecast temperatures would rise by between 1.1 and 6.4 degrees Celsius this century.
By 2100, water scarcity could impact between 1.1 and 3.2 billion people, says a leaked, related U.N. climate study due to be published in April.
China and Australia, as well as parts of Europe and the United States would face critical water shortages, it says.
Maritime experts say shipping water by tanker is one of the least eccentric ideas raised of late to counter acute shortages.
Dragging icebergs from the Arctic, ships hauling enormous bags of fresh water, and cloud seeding -- in which clouds are sprayed with chemicals to induce rain -- have all been aired by water authorities in the past. |

| Why not build water desalination and purification plants along the coastal areas and set up a pipe system to transport fresh water inlands ? |

If they are along coastal areas, i hope they float. :wtf: |

Oil pipelines are going to be replaced with water pipelines, sucking the precious dihydrogen oxide right out of the glaciers ;-) with the help of water miners, of course :stongue: |

eh ?
Well how do they intend to transport the fresh water from the supertankers to the parched cities ? Desalination plants IMO will be a lot more efficient than transoceanic tankers. Of course whether they are economical or not remains to be seen. But my guess is that desalination should be cheaper as the technology improves.

Desalination refers to any of several processes (e.g. reverse osmosis) that remove the excess salt and other minerals from water in order to obtain fresh water suitable for animal consumption or irrigation, and if almost all of the salt is removed, for human consumption, sometimes producing table salt as a by-product. Desalination of ocean water is common in the Middle East (because of water scarcity) and the Caribbean, and is growing fast in the USA, North Africa, Spain, Australia and China. It is used also on ships, submarines and islands.
Desalination of brackish water is done in the United States in order to meet treaty obligations for river water entering Mexico. Several Middle Eastern countries have energy reserves so great that they use desalinated water for agriculture. Saudi Arabia's desalination plants account for about 24% of total world capacity. The world's largest desalination plant is the Shoaiba Desalination Plant in Saudi Arabia. It uses multi-stage flash distillation, and it is capable of producing 150 million cubic meters of water per year.

More heat = more evaporation = more rain?
I guess not? |

No, you're right.
More evaporation = stronger storms |

That's the same thing I was gonna say.
Earth is covered by water 75%. You figure if science can get oil out of the earth it can get water out of the ocean.
But no, they would have you believe that there is a water crisis after they've just told you there's global warming and that whole "The worlds ice is melting!" concept. Not to mention the supposed shortage of oil. Remember oil is a hydrocarbon. Just like they can make synthetic oil they can make synthetic gas or even hydrogen fueled engines.
But this is a "water shortage" thread. Carry on. It does sound silly when it says about shipping water aboard boats when the ship is on water already. |
