With sea levels rising (8in/20cm in the past
century)
and global temperatures rising (about 1degC /
1.8degF in the past century), it's about time we
solved the problem.
The proposal is quite simple: Build an inland sea
in
the middle of the biggest empty spaces you can
find (Central
Australia; Sahara; Southern Russia)
and
store water there.
Firstly, build a very large wall around the new sea.
Then pump lots of seawater into the new
reservoir.
Use heat exchangers to store excess global
warmth in the
water.
Next, establish an aquaculture industry, to grow
food.
Finally, put a roof over it all, to prevent
evaporation
and to reflect heat back into space. Some fresh
water can be harvested from the system, using
condensation.
Covered off sea levels, heating, food production,
heat absorption, fresh water production.
Taking the rest of the day off now.

None of it deals with the other issues I raised, I found. |
|
| |
Roof it with a floating membrane, with frequent anchor points to keep it stable. |
|
| |
Select an area that includes a place with rain and you won't have to pump water in. |

Might want to seal off the bottom too to prevent losses that way. |

We would probably be better off to just accept the gradual sea level rise, and allow the insurance companies to pay off people and businesses who need to move due to storm damage. The insurance companies will force moves, as they do today in flood areas, by raising rates. |

Surely we could achieve the same result, in terms
of seal evil, simply by lowering the existing ocean
floor by 8 inches? |

I reccommend that, henceheretoforth, all fishing
fleets that use those bottom-dragging nets should
be obliged to dredge up a few tons of mud with
every haul. Within a definite period of time, the
dredging would be complete. |

Obviously, we would need somewhere to dump all
of the salt-rich sludge, but I'm happy to go along
with [Ubie]'s suggestion to use Australia for this. |

New Orleans USA, Bangladesh, the Netherlands, and a few low-laying Pacific islands would probably want some of the mud. |

We've already got the nuclear waste from Britain's
weapons tests in the 1950s. You can have that back
first, [Max]. |

//dump all of the salt-rich sludge// Could we add in all that horse contaminated Romanian meat? (I hear they'll eat anything down there - even bits of themselves) |

We were discussing water scarcity problems over lunch
today and I mentioned this one to a couple of engineers.
Fun to see their eyes light up with the possibilities. |
