Haiti

Wear your badge with pride Sir.

Wasn't that what I was saying?

Don't follow the gourd.

Follow the shoe!!!

This is UKRM.

 

I never bothered with a computer and all I ever did on new dives was
to have a set of laminated US naval tables I could have a squint at if
I thought it was getting a bit dodgy.

I did shit myself on one occasion when I'd been doing a lot of dives
that had a profile resembling a sine curve and I developed Bells Palsy
for reasons totally unconnected to diving. A 'friend' of mine who did
a lot of cave diving but was also a doctor persuaded me that the
reason my facial muscles decided to stop working was because I'd got a
small neurological bend. Try to imagine the scene where I was sitting
dribbling as I drank my beer and said 'friend' was trying to persuade
me that I needed to go to hospital immediately or I'd die.

Needless to say I didn't go to hospital but I didn't sleep that well
until I'd been to see my doctor about 36 hours later. Worra ****.

 

To whom?

I agree but we are not changing climate by the amounts touted about by
the IPCC.
Their data base appears to be flawed in many areas, due to bias cause
through self interest, state interest or large egos.
The sloppy way they have trawled data in from already flawed sources
(not known to be flawed by them at the time. eg UEA etc) without
adequate cross reference puts their data and predictions in to doubt.
Plus the good stats they do have are loosing credibility through
governments who tout them about for the sole reason of imposing higher
taxes in the name of 'Green' which is actually spent elsewhere.

Which is unfortunately true.

I was told by someone on the Kent Council:

If where you live, is anything like Kent was when I lived there, make
sure you don't pay your council tax bill till you get the *very* last
reminder.

The way they selected jurors by their 'automated' system, this precluded
you.

It worked for me, but may not work like that anymore.

 

Crickey, I used to get worried about every little tingle or muscle ache.
Doing a regular fitness work out during the same period didn't help things
as I always had muscle aches.

Had my face stopped working, I'd have been upto the chamber like a shot.
Mind, it helps when DDRC[1] are just up the road.

Actually, I think the 'needless to say' part is that you're clearly
fucking bonkers.


[1] For non-divers: Diving Diseases Research Centre, who have a number of
hyperbaric chambers[2] and are the country's leading experts in fixing
bends.
[2] Our dive club did the obligatory "dive" in one, where we went to
around 40m or so. I can't really remember the point now.

 

Imagine it?! I've *seen* it.

 

I was sitting in a bar in Bradford where I was stopping for a caving
conference. There aren't many pots around Bradford so there wasn't
much point in worrying about it.

Why waste time sitting in a hospital waiting room where you've no
chance of seeing anyone with a clue? Sod that, just carry on as normal
and don't let the fucker know he's got you worried.

I never did get to stitch him up as horribly as he managed to do to
me and that's one of my only regrets in life. I could never hate
someone who'd cheerfully do that to a mate because it showed a genuine
lack of feelings that can only be envied.

I've slept in a couple of decompression chambers when I've been
working offshore on dive support vessels and having to share cabins
with a snorer. They're not the most comfortable of places to sleep but
you know nobody will disturb you unless there's a major **** up with
one of the saturation divers.

 

I would be interested to try a pot dive to find the level I would be
aware I'd get narked at.

I've been in the sea below 40 on air and did not 'notice' any effect.
Except I sucked up air fast.

On a deep dive test with a female instructor, she wrote something on a
slate for me to work on at depth (A calculation of some sort to
demonstrate to myself how easy it is to get narked.)

I wrote something underneath.

She looked at it and shook her head and wrote something under that.

I wrote under it and handed it back.

She looked at it and shook her head and wrote something under that.

We stopped that and went on to other things.

When we got to the surface after the dive, she got the slate out and
there was an odd scrawl like a spider crawling over the slate with my
handwriting in capitals under it saying
"I can't read your writing."
This was repeated twice.

Is it Ostioperosys that saturation divers suffer from in the end?

 

How come when Des gives us a Jew lesson, I get not just pissed off, but
bored stupid and yet when you give us a history lesson on you chosen field,
it's actually fucking interesting. And I barely understand word one

Either That was a Whoosh or a typo?

I 'm saying natural climate change is a fact of life you say it's
irrelevant then say it's relevant to the people that it effects?

For example, relevant to my original comment, but not your postulation
that you introduce then ask me to refute.
(Poor 6th form debating techniques, you'll make a good MP > )

Me too, be a bit of a giggle once. My experience in a pot is breathing
O2 at 18 metres.

Depends so much on conditions, on how you feel, but there would be
some effects at 40 metres. I've been noticeably narked[1] at 50 on air
and likewise felt fine at 60[2]. Going back to 60 on trimix brought it
home just how slow I was on air.

Heh, mind writing on a slate isn't that easy even without N2 helping.

[1] Couldn't even remember how to work my compass, vision closing in
from the sides, massive paranoia - not nice at all.
[2] Only difference that I can recall was not wearing a drysuit and
felt fine but was really aware that I was not totally with it.

 

I agree but with the caveat that it may happen sooner.

I don't follow you there.
0/10 for comprehension again I suppose.

I'm glad we agree on something, but I'm not sure what.

I do like this:

I still believe that our input into the system is not a patch on a good
volcano. I know you quoted 3 days of US cars is the same as one volcano,
but that is being very selective with data and only CO2.

From what I recall of my training, I am sure they told us pure O2 was
lethal way before 10m?

Deepest airdive was the on I posted earlier at 43m and I could feel
some mild effects coming on. Looking at camera and taking longer to
change settings.

Hehe, oops.

 

Just back from Sunday lunch at the pub. I may or may not make sense.

Climate is defined in tens of years to thousands of years.
So yes.
Other wise it's weather.

I still reckon you have to take into account the naturally occurring
triggers.

Sorry got it wrong.

What I remembered was that the statistic you quoted (in general) was
quoted on a televised bit on 'The Climate Conference' in Copenhagen and
then I thought how misleading it was. It was in a subsequent interview
during this programme about the conference that the original question
was placed about Milankovitch cycles.

Ooo Please Sir can I Google. Maybe later.

I've been relying on old memories of 20 odd years of access to shed
loads of satellite data from which my basic premise originates.

The dust and aerosols other than CO2 from a volcano by far out weigh the
effects of the CO2 (depending on the type of eruption).

CO2 on it's own I agree with you.

Sulphur aerosols modifying climate, warm the stratosphere, and cool the
troposphere they also promote the destruction of the Earth's ozone layer
significantly.

Only recently has the effect of this warming and simultaneous cooling of
layers of the atmosphere been understood. Atmospheric thermoclines
(tropopause) are a barrier to the movement of the upper atmosphere.

This effects the temperate low pressure belt that Northern Europe sits
under and the position of the Jet Stream which is close to the altitude
of the tropopause.

It's primarily the Jet stream running along the south of France rather
than the north of Scotland (where is should be) over the last couple of
months that has been blocking the weather pattern over us and giving the
cold weather.

Sulphur aerosols are considered to be far more potent an effect on
change than the contribution of CO2 ton for ton. (Plus the ozone bit)


The quantities of SO2 are *approximately* 50/50 man burning fossil
fuels, from manufacture etc and natural sources, volcanos the biggest,
then biological decay forest fires etc..

The 'natural' statistic is based on an average emission from an average
number of erupting volcanoes over a period that excludes massive
eruptions to form a base line.


Now add to that the cooling effect of dust ejected high in the
atmosphere and you get an *instant* 'in climate terms' change in
temperature.

The guys working in the same organisation as I was and using satellite
derived data, concluded that *if*:
4 big eruptions or one super eruption happened in one year, it could be
the trigger of an ice age of some sort. This was likely because of the
current position in the climate cycle made us vulnerable. (Also to man
made input.)

Now for the google bit. And think back to the:

And me saying it only takes one volcano having a bad hair day to have a
greater effect.

The Laki eruptions 1783 ejected ash and vast quantities of sulphur
dioxide (SO2), hydrogen chloride (HCl), and hydrogen fluoride gases
(HF). U.S. data indicate that record lows occurred during the winter of
1783-1784. Temperatures decreased about one degree Celsius in the
Northern Hemisphere overall.

1815, Tambora propelled more ash and volcanic gases into the atmosphere
than any other eruption in history and resulted in significant
atmospheric cooling on a global scale. 'New England' and Europe were
particularly hard hit, with snowfalls in August and massive crop
failures. The climatic effects of the eruption had 1816 known as "the
year without a summer".


1883, Krakatau eruption (West of Java not East as in the film!) ejected
about 20 cubic kilometres of material in the form of ash and aerosols
into the atmosphere. It lowered global temperature by nearly one degree.

More recently

1902 Santa Maria and Mount Pelee

1912 Novarupta

1980 Mt. St. Helens eruption lowered global temperatures by about 0.1
degree C.

1982 El Chichon, had three to five times the global cooling effect world
wide than M St H. Despite its smaller ash cloud, El Chichon pumped out
more than 40 times the volume of sulphur rich gases produced by Mt. St.
Helens

1991 Mount Pinatubo eruption ejected about 17 million tons of SO2, just
twice that of El Chichon and cooled the northern hemisphere by 0.6 deg
C.

1995 1997 Montserrat's Soufriere Hills the effect was felt world wide
with a combined cooling of 0.4 deg C


If you take out the effects of volcanoes you get a much different
picture of what is happening. This is from a non believer Steve Goddard
who was dismissed by the IPCC but they could not refute his data. It was
the same they were using.

http://wattsupwiththat.com/2009/01/13/how-did-the-el-chicon-and-pinatubo-
volcanic-eruptions-affect-global-temperature/


Google is your friend!

I love it!

 

So
We have agreed that some of the IPCC data was of dubious source.

We have agreed that not all of the member of the IPCC are the sharpest
knifes in the kitchen draw.

We have agreed that volcanos can screw up the climate short term more
than humans.

We have agreed that Steven Goddard can take the same data used by the
IPCC, play with it a tad, come out with the same result but the IPCC
disagree with the result but did not disagree with his method. (If you
have the time to read through the lot and the links.)

My work here is done.

There's no safe elevated PPO2, however, most[1] agencies recommend not
exceeding 1.4 on a dive and 1.6 for OC deco[2]. So 6 metres for deco,
the military often will use a PPO2 of 2 but with full face masks. The
most likely consequence of high PPO2 is a full on spaz fit, in a
chamber the idea is to drive out the N2, it's dry and there's a medic
in with you. Underwater without a full face mask you'll be sucking
water.


[1] it's probably all but knowing my luck there's be an odd one.
[2] there's also CNS loading and daily OTU to consider.

 

That's how I under stood it.

A diving mate of mine who has a dodgy form of diabetes, dives with a
full face mask for similar reasons. ie: A possible full on spaz fit.

 

Yeah, the 1.4 rings a bell, about 4-5m. But I'm positive they told us
it was mmore from toxicity than convlusions, but I guess that is
probably one outcome of toxicity. I had always been under the
impression you'd just become unconscious. Learns something every day
ya does.

Kev

 

They could fucking spend money though and I was once the recipient of a fair
amount of it.

Heh my first Grad Student job was on the Truck & Bus plant in Leyland. What
a bunch they were. Years later I bought a rather minty Allegro however,
pressurised the suspension to lift it 4 inches over stock and we used it for
forest tracking. A jolly fine cross country missile built on a solid floor
plan!

The hydroelastic doohickeys sucked it all up. Its reign was only terminated
when the front/rear pipes were taken out and it flopped onto the stops. TBF
the sheep embedded in the radiator didn't help. Never did like Mutton.
