How effective would man-made oceans be on preventing the global catastrophe of climate change?

Let see if you wish to cool the earth set up a lot of mass drivers on the moon and place mega tons of moon dust in low orbit around the earth.

Or just kind of nudge it over so we always benefit from solar eclipse.

I recently saw it on DVD. In a movie mazagine she admitted that Cary Grant proposed to her but she turned him down for Carlo Ponti. Cary seemed rather depressed in the movie. There were a few TV stars in the movie. The kid was Peterson in the Donna Reed show and the Italian actor Guardino or something....Sophia was escaping from her high society family and end up being nanny to the divorced Dad or widower.

Also, the sun could evaporate the sea water to get salt as is done in Thailand. A salt factory could be built. The sun rays could be harvested to produce electricity. A harbor and resort and maybe some agriculture from desalted water.

Egypt/Libya would be perfect for the purpose.

Plenty of dry up lakes beds where salt can and is now being cheaply mine by the mega tons so there is zero need to do the evaporate route to get salt.

The last such project in the US was over a hundred years ago in Key West.

I don't feel there is any intelligent discussion with you. The sun just evaporates the water so salt is left. There no extra energy involved.

The oldest continuous business in the Americas, is in Puerto Rico where they still get salt from salt beds, harvested in the same ancient manner the native islanders did back before they even knew of white man existence. They still use the power of the sun like most salt production in the world.

If this massive lake/ocean/sea were to be built, where would you put the excess dirt? Or would you create a new mountain range too?

The

As there is plenty of cheap and almost unlimited salt supply now why would you do so?

What economic justification would you have for dong so?

The world can use more parks and animal sanctuaries built on landfill (excess dirt and such).

I wonder if this extra debris could be used to rebuild the marshlands and swamplands in Louisiana and New Orleans?

Yep. The world is not in some kind of salt shortage or is it?

The UN stated that it wanted to reduce desertification occurring around the world from destruction of forests, over grazing, converting forests to farmland and so on. With World Bank funding the depression in Egypt could help Egytians have a resort area next to the pyramids. The Australian depression is in Lake Maurice area in Aboriginal lands could help build up a habitat for all kinds of fauna and flora and improve the life of the Aboriginals. The Salton Sea could get World Bank funding for a canal up the Gulf of California and eventually to Death Valley. Then there is the Dead Sea canal to Red Sea. These projects could have hot houses that collects the vapor then stored it in tanks underground as desalinated water. These projects could also lift the world economy by employing millions of people and help cool the earth and bring deserts to some use.

There are many uses for salt.

Getting future funding from the World Bank to drill a canal to Death Valley from the Salton Sea could help Las Vegas with a resort lake and fishing if stocked with salt water fish.

Ambitious projects that most likely will never see the light of day. <<<sigh>>>

You mean, Las Vegas would be above water - unlike their home mortgages?

Now now... let's not kick em when their down.

No, the Death valley lake resort would give vacationers another venue in addition to gambling and getting at the chicken farms.

The world economy needs a boost and funding these green projects could lift it.

The world economy needs a boost and funding these green projects could lift it. They are not that expensive. Drilling and tunneling. There are tunneling machines that bore 10 or 20 feet diameter at 100 feet a day. A few billions which the World Bank could easily fund and let private enterprise take care of the resort hotels and boating.

I wonder where World Bank gets its money.

All that loot from Wall Street.

Smack your phonograph. The needle's stuck.
