The Extra Molecule
Please tell everyone you know that this story has nothing to do with climate change ......

Seven taken to hospital with carbon monoxide poisoning after gas leak in Sydney home

Carbon MONoxide (CO) is a poisonous gas. Carbon DIoxide (CO2) is a harmless airborne plant 'fertilizer' currently greening the Earth. Please don't confuse the two.

The world has succumbed to smarmy spreadsheet magic pudding nonsense about wind and solar that simply does not add up.

RE: The Extra Molecule
During my time with Fire & Rescue NSW, I attended numerous cases of carbon monoxide poisoning.
Unlike CO2 or asphyxiation which simply robs the lungs of air....and can be resuscitated sucessfully,
carbon monoxide is a poison which can linger in the body for quite a long time, requiring specialist hospital ER care. Even then, it can be fatal.
Carbon monoxide has 210 times greater affinity for haemoglobin than oxygen.
A small concentration will thus cause toxic levels of carboxyhaemoglobin which is fatal if not treated.
Usual causes are the old suicide hose from the exhaust pipe of the car, straight into the passenger cabin of a car.
Two minutes of this and you're dead.

By stark comparison, people who die from Carbon Monoxide poisoning have a rosy skin colour which almost looks healthy....
Whilst those who die from CO2 asphyxiation exhibit a blue/pale skin colour, which is simply due to lack of oxygen.

Terra, what level of CO2 does it take to asphyxiate an adult human in a confined space?

RE: The Extra Molecule
Geez Don.....I ain't a scientist so it's like asking me how long is a piece of string.
We inhale air which has 21% oxygen and when we breathe out, it's 16% oxygen. Our body absorbs 5% oxygen and breathes out CO2 as "waste".
Excess CO2 in the atmosphere encourages us to breathe in deeply and more often.....much like a person who has just run 100 metres.
So....a build up of CO2 in a small room could make us breathe deeply, or yawn, or just sleep or become unconcious. It ain't poison like carbon monoxide but it will kill by suffocating.

This snippet from Wikipedia.
Inhaled air is by volume 78.08% nitrogen, 20.95% oxygen and small amounts include argon, carbon dioxide, neon, helium, and hydrogen.

The gas exhaled is 4% to 5% by volume of carbon dioxide, about a 100 fold increase over the inhaled amount. The volume of oxygen is reduced by a small amount, 4% to 5%, compared to the oxygen inhaled. The typical composition is:

5.0–6.3% water vapor
74.4% nitrogen
13.6–16.0% oxygen
4.0–5.3% carbon dioxide
1% argon and several parts per million (ppm) of hydrogen and carbon monoxide, 1 ppm of ammonia and less than 1 ppm of acetone, methanol, ethanol and other volatile organic compounds.

RE: The Extra Molecule
butbutbut .. breathing doesn't produce or manufacture CO2 it just expels what was inhaled doesn't it?
presumable farting does likewise. I get that biological processes produce methane but it's only CO2 that offers the chance to be taxed so it gets all the value attributed to it.

... never mind, just waxing philosophartical... it's too early to think yet.

RE: The Extra Molecule
I found this which I haven't fully digested: Submarines Air Quality

In submarines, higher CO2 concentrations are permitted, usually 5000-7000 ppm ...

Breathing doesn't produce CO2 but the cellular process of using oxygen to combine with digested food molecules, in particular glucose, does produce extra water, carbon dioxide. It is a kind of slow combustion that gives us the energy we need for life. Water is eliminated by the kidneys, the skin and the lungs and the extra CO2 exits in exhaled air. Every living thing produces CO2 in this way but plants absorb more than they produce as the result of photosynthesis.

Farting releases methane and some sulphurous gases.
CO2? Not really.
