CO2 isn't really toxic, but it's heavier than O2, and tends to displace it. It's not the CO2 that kills you, it's the lack of O2. Indoor levels can get up to 1000-1200 ppm pretty easy, if there is limited fresh air circulated in to the room/building, which is common these days. We tend to 'weatherseal', to save money on heat/cooling, keep out moisture, dust, and other environmental crap. I suppose the indoor 1200 ppm would get reached quicker, if the outside level is higher. Simple enough to fix.

A very small part of it may become carbonic acid for awhile, but usually it's just dissolved in ocean water. BTW, carbonic acid is also reversavle, forming dissolved CO2 again. Both reactions reach a state of equilibrium when airborne CO2 is dissolved in water, and the water vents CO2 back into the air again; and when CO2 becomes carbonic acid and carbonic acid becomes CO2 again. There is also a myriad of plants in the ocean water, including of course plankton, which are tiny plants using photosynthesis to obtain their energy. Tiny as they are, the effect of these things is quite significant. Oceans cover 70% of the Earth's surface. Industrial areas, where there are factories and cars spewing a lot of CO2 into the air, cover only about 1% of the Earth. To run these devices and factories requires fuel, and it costs money. Much of that fuel is from the result of CO2 and hydrogen reacting in the ground under tremendous heat and pressure in the presence of an iron catalyst, producing oil and methane. So all you are seeing is CO2 recycling as part of the normal carbon cycle. Even much of the fuel we use comes from CO2, either converted into oil and methane by a Fischer-Tropsche reaction that naturally occurs underground, or by conversion to carbohydrates by plants. Both oil and methane come oil wells, and methane is easily obtained from plant material...or you can burn the plants directly (such as wood and brush fires). Even paper and other burnable trash can be used to obtain energy. Such facilities have already been built to produce power. No. We can't produce enough CO2. Normal carbon cycle, and the CO2 cycle with it, simply helps to make the fuel we burn, and is what keeps the Earth green. Can it warm the Earth? Experiments have shown that if you quickly release CO2 from a pressurized tank into an area of lower pressure, such as the atmosphere, you get dry ice. Releasing it at a slower rate is really good at extinguishing fires. We also know that dissolving it in water to make soda water does not heat the water.

Problem 1: Redefinition of "Poison/Pollution". The definitions of "poison" and of "pollution" are independent of quantity because everything is fatal at some quantity ... and warmizombies use this fallacy to call CO2 a poison and pollution ... and rendering everything else as poison and pollution in the process. CO2 is only a poison if nitrogen is a poison, or pure water, or oxygen. When everything is poison and pollution then nothing is poison or pollution. If I take a shotglass full of industrial waste goop and I dump it into Lake Tahoe, I have polluted Lake Tahoe. The police won't let me walk when I point out that I dumped "too little" for it to be pollution. CO2 is not toxic to humans. You have a lot of it floating around in your body every moment of every day of your life. Problem 2: The Red Herring. When you breathe in a gulp of air, it is essentially 20% oxygen and 80% nitrogen. What do you honestly believe would be the net effect if you were to breathe in a gulp of air that was 20% oxygen, 75% nitrogen and 5% CO2? Notice that we still have 20% oxygen. What do you think will happen? Ergo, you should not be talking about CO2 from the false perspective that it somehow is a poison but instead be talking about the effects of breathing insufficient oxygen, whatever the cause, e.g. high altitude, CO2 displacement, etc... . I don't think i can [define it]. I just kind of get a feel for the phrase. - keepit A Spaghetti strainer with the faucet running, retains water- tmiddles Clouds don't trap heat.

I have had a good think about this and its more than a little out there.I am sure they are just missguided do gooders and I hope to open thier minds then I woke up To me, CO2 is pretty important stuff, for a trace gas. Every living thing on the planet is made up of carbon-based molecules. Plants are the only living thing that actually gets carbon from the environment, not other living things. CO2, is that carbon source in the environment. Plants need about 180 ppm, minimum, less and they are starving or dying. There is a lot of information on the ideal levels of CO2, which is around 800 ppm, although there doesn't seem to be an upper limit. Beyond 800 ppm, there is just little or no, noticeable benefit. OSHO believes 1200 ppm is a safe level to work in. Most all commercial indoor growing/greenhouses, augment their CO2. Their plants are healthier, grow faster, more productive, profitable. Lot of research online, and there is no question about the benefit. The climate change people want to reduce the atmospheric CO2, to about half, which is obvious very close to starving plants. They screw it up, and they are going to kill off much of the plant life, not much of a buffer zone. On the other hand, if we double the CO2, plants get as much as the want and need. More productive crops, quicker, and less likely to fail. Plenty of food for everybody. Bears would have to knock over trashcans anymore.

It does the same job as 'flux' in stick welding, but is better at it. It can be used for MIG or TIG welding. Argon is mixed in for some types of welding, since CO2 can react with the hot metal, hardening it, when used by itself...although the effect is pretty minimal, since the weld covers such a small relative area. A lot depends on how the metal is cooled after welding as well. The CO2 is released through a regulator, limiting the pressure to only 5psi or so. This is a pretty slow release of the contents of the tank, and could last for a long time (depending on the size of the tank). This is not enough to cool anything much.

Yes. It is the Holy Duty of the Church of Global Warming to destroy anything that burns carbon. All industry burns carbon...even nuclear power plants (they have vehicles and tractors that burn carbon). duncan61 wrote: I am not a fan of digging coal and using it to create steam to turn turbines to create power it seems so out of date but as we know the market dictates what works and what does not. It is certainly not out of date. Coal is very cheap, While plants are closing in the UK and a few the United States, new plants are being built in India, Malaysia, China, and Indonesia. Much of the United States still uses coal, especially in the East and Midwest. Coal is essentially pure carbon (with impurities of various kinds, depending on the quality of the coal). It is not known what creates coal seams, but we do know there is plenty of the stuff (hence the cheap price for it). It is easy to obtain, transport, and handle. It can also burn very cleanly, given a properly built plant. duncan61 wrote: I was involved in a project where the Aluminium refinery that is inline with the main power lines that run from Collie to Perth did a deal with the state government and Alinta gas and run the turbines at 50% and dump the extra power in to the grid.
