The polar ice caps are melting and accelerating global warm, but
the
stupids haven't yet realised that all this melting is happening at
the edged. So the solution. Simple. If they can build huge ten
thousand mile long oil pipelines to bring oil from Central Asia to
Europe why don't the build a pipeline to pump water that's been
generated from the melted ice to the centre of the ice caps where
it
will freeze back into ice again, and won't melt since it colder
there
than at the edges. What's more this will break the vicious circle
of
global warming.

The trouble is, there's this little thing called "the conservation
of
energy" and "the second law of thermodynamics". I'm surprised you
haven't
heard of them, what with your science degree.

The pump will need energy to work it, and like all mechanical
equipment
it
will generate heat as a by-product. It could end up making the
global
warming even worse!

Obviously you've not heard of something called radiation. Once the
water
has
reached the pole it will give out its hear into outerspace, therefore
cooling down the planet, thus you are killing two solar penguins with
just
one stone.

Good idea for a Doctor Who story, right? Afer all if RTD can set
the
Easter special on a London buss in the middle of a desert why
shouldn't someone else set one on the polar ice caps and there
could
be a monster on the loose knocking off the pipeline line workers..
It
could even be a good way of bringing back the Yeti.

<<<Immaterial. The total heat generated by the system will exceed the
heat emitted as radiation, even if that heat ever reached space.
(Since radiation is in all directions, half will melt the ice below.>>>

Ice is white. Most of the heat will get reflected.

<<<Aggy, (sigh).. color doesn't matter when talking HEAT. Color only
matters when talking about LIGHT.>>>

Heat is a form of infra-red electromagnetic radiation. Colour matters.

Since you can't spell Colour correctly I take it that you're a yank. It
seems US schools are now as useless at teaching science as UK schools.
Letting them off with bad spelling seems to have made things worse.

That's the whole point of

the polar ice caps being there to begin with. If the north pole melted
the
sea levels wouldn't be affected because the displacement of the ice is
the
same as the water when it is melted.

<<<Not so. H2O is a unigue compound in that when it is liquid it takes up
11% less space than when it is solid (ice).>>>

Here we go again. You are wrong. Ice unlike most other material actual
expands when it freezes. That's why pipes burst in very cold weather. Ice
takes up 11% more space when it freezes. That's why 9/10s of an iceberg is
underwater.

<<<Didn't I just say that water as a liquid takes up 11% LESS space than
when it is solid Ice)?>>>

I must have misread what you said.



Don't they teach Archimedes' principle at UK schools anymore? This is
pre-O-Level stuff. An iceberg will displace the same amount of water as
its
weight, therefore since icebergs float it would only be displacing the
same
amount of water as it would when it melts.

<<<Dickwad. Volume and weight are two different things Aggy.>>>

What is ice made of fool? Oh, could it be water. Now I wonder how many kilos
of frozen water it would take to displace one kilo of liquid water. Might it
be one?


Your math is correct on that one concerning WEIGHT my little tinfoiled
friend. Now explain to me about VOLUME.
I'll give you a hint: water takes up 11% more space when frozen.




I bet you think ships float because someone is stopping them from sinking by
holding them up with their hand.







What you would lose is a reflector of

the suns heat, so most of it would go into heating up sea water.

<<<That which is going up will largely be reflected by clouds or
absorbed>>>
by the atmosphere. Very little will escape. Since the amount

Wrong. It's ice caps on the poles already do.

<<<to reach this point vastly exceeds the little that does go
extraplanetary, you've merely warmed the planet up.)>>>

No. Even if some of the heat goes into the ice, it won't be enough to
melt
it. There's 2 miles deep of it and it's at -80 degrees. All that will
happen
is that the heat will be stored in the ice and radiate into outer space
over
time.

You obviously do not understand the basis principle. Heat radiates into
outer space anyway. Pumping sea water onto the ice caps increase the
rate
of
cooling like spilling tea from a tea cup into the saucer. More first
year
Middle School/Primary School science you didn't learn.-

<<<Aggy if you are pumping water that is *just* about at the freezing
temperature of sea water (at a particular salinity. Atlantic being
saltier than the Pacific) you just might get away with it. However
what if you are pumping 40F water? There's 8 degrees of temperature
that has to do someting to the ice you are pumping it onto.>>>

Look at how big a heat sink the ice forms and work out the energy it needs
to raise the temperature by 1 degree given the heat capacity of ice. The
amount of water needed to be pumped to do the job of global cooling will
hardly affect the temperature of the ice. Just as long as it remains below
0C it will stay as ice and eventually get colder by radiation.-

<<<Yeh, as long as the water you pump onto it is 0C.>>>

You obviously haven't learned about heat capacity and specific latent heat.- Hide quoted text -
