Cape Town Harbour under threat from rising sea level

[Londo]

Africa's harbour cities of Cape Town, Lagos and Alexandria are under threat from rising sea levels which could displace millions and cause massive economic losses, scientists said Wednesday.

Speaking at an international climate change conference in Cape Town, Geoff Brundrit of the Global Ocean Observing System in Africa said even a slight increase in sea levels could wreak havoc on some countries.

Can't we reuse sea water for other stuff?

Like, pump it in land to use with power stations or something.

LOL@myself

Thus, using it and EMPTYING the ocean?

Hey one should never underestimate any idea.....ok some you should

Mmm, now there's a idea. Only problem is pump it where to? I mean the surface are of the sea is much much more than that of our little country

Dig a beeg hole in the kalahari somewhere, and pump it in there, the heat from the earth's core will heat it, and turn it into steam, which can be used in steam engines, to make power, thus helping Eksdom ook.

Now there's an idea!! Hydrothermic power

Don't worry Kaapies! We'll still come down to Table Island for the odd holiday.

Table Island - the new Seal island.

They've been saying that for dogs years. By the time the sea rises and swallows our homes it won't matter as we will all be safely inland behind high walls drinking our food through straws and getting wheeled around in those chair thingies.

Watch the Siener van Rensburg acolytes crawl out of their holes over this.

Beats my idea...

I was going to say, cover the Kalahari desert with water, maybe something will grow!

I know, it could just be stored as masses of ice ... all you'd need to do is figure out how to cool the Earth's climate a couple degrees and this should happen on its own.

What would the harm be in pumping sea water into deserts?

Just build giant fans all along the coastline to blow the water back?

What power would u use to pump it with? There would have to be a big advantage for using it.. like power consumed << power generated. Isn't it also the reason koeberg reactor is on the coast?.. of cause the water temp in the immediate area also increased changing the natural ecosystem.

Dunno.. you know.. if salt was profitable we could, after pumping sea water inland to the karoo create an artificial salt pan? ok.. smaller scale would be a salt evaporation pond..

But remember the water in the gran scheme things is not disappearing as such, it just changes to another form and comes down as e.g. rain elsewhere in the world which still runs into the ocean.

Another idea might be to, pending rock types and perhaps preparation of rocks, create artificial dams inland but not above ground but in unused mines.. of cause it depends on whats in the mines as you don't want a lot of polluted water either.. imagine we could create an artificial underground water source and pump lots of desalinated water in. No more evaporation problems too..

Plants grow when watered with salt water?

There's a large dam there IIRC somewhere around Graaff-Reinet that's bone dry. You could start there

EDIT: Sorry not the Kalahari the Karoo *facepalm*

I know about that dam yes, It was built on the wrong place - quite sad actually. Will be good if we could fill it up!

LOL!

I know they can't, but I've heard that sand does things to water, it filters stuff...

They say SA is going to run out of water in the near future so why don't they build a couple of Desalination plants near the coast?

We can waste the seas water can we after all there is soooo much of it.

Doubt it needs pumping, most desserts used to be big salt lakes anyway - sea basically.
