Trust you, you are the alarmist, everything bad can happen, though youBill Slomanwrote:

One can wonder what the real truth is, about temperature, and then again about
what causes it, you know there were, and will be, ice ages, nobody
was having coal plants in the previous one to create CO2 (in the Netherlands they now want to store the CO2
in the ground under my house almost), so, all feeble science.
Time to sell? Once this sort of "project" has moved along far enough you
might not be able to, for the price you'd want.
Could be, I already looked up if CO2 was heavier then air (it is):

else it would be very dangerous to live here.
But some geological processes could push it upwards, you would get suffocated in your sleep,
nowhere to run, even if you found out what was happening.
CO2 detector, oxygen equipment, fast car or helicopter, and you MAY have a chance
If for some reason pressure shifts down there and a bubble gets pushed
up you may not have time to start the turbo-shaft engine in your
helicopter. Besides you sitting there slumped over the controls, it also
needs some oxygen to work.
Of course, if this were likely to happen, Barendrecht would have
vanished in a giant fireball sometime in the last few thousand years,
when the - now exhausted - natural gas field under the town had pushed
a bubble of natural gas up to the surface.

snipped the rest of the idiot anxieties
Oh yeah?
http://en.wikipedia.org/wiki/Lake_Nyos
Lake Nyos is a deep lake and the water was saturated with CO2 from the
bottom up. The pressure at the bottom of the lake is a lot higher than
at the surface, so the CO2 concentration at the bottom of the lake was
a lot higher than that at the top.
This is an unstable situation, and once a part of the deeper water
started moving towards the surface, the CO2 started coming out of
solution, making that volume of water and CO2 less dense, so that it
rose more rapidly.
As your web-site says a "300-foot (91 m) fountain of water and foam
formed at the surface of the lake".
The CO2 to be stored a couple of kilometres under Barendrecht, in an
exhausted natural gas field, would have a rather tougher time getting
out. The natural gas field held the the natural gas under Barendrecht
without letting it out since Barendrecht started keeping written
records, and most likely for a few hundred million years before that,
so the two situations don't seem to be entirely comparable.
And then homo sapiens began poking holes into it using drilling rigs.
Very closely guarded, of course. This sort of guarding is unlikely to
continue once the financial interest is gone. IOW after the revenue from
gas is exhausted.
And the natural gas field that used to be there didn't survive an
earthquake or two over the couple of hundred years it was hanging
around waiting for ome Dutchman to drill that hole?
Not an earthquake that was able to rupture things down there. A drilled
hole, very different thing. And yes, I did work in an oil field and went
through the scare when the gas bubble siren wailed. Pretty much
smack-dab in the middle of the North Sea, on an anchored
semi-submersible. Definitely not a great place to be when a bubble wafts
upwards. Luckily it hissed off and I am still here
Even granting a slow leak through the pipe that they are now going to
use to put CO2 into the gas-field, there is a couple of kilometres of
water saturated geology between the gas-filed and the surface. You
aren't going to get a Lake Nyos-style 300 foot geyser of CO2, just a
bit more calcium and magnesium bicarbonate in the ground-water.
Trust us, we are the government, nothing bad will happen. Yeah![]()
don't know quite how. Your imagination could use a little more
discipline.
