Solidified carbon? Do you mean elemental carbon, C? Or perhaps you mean carbon dioxide, CO2 Or maybe calcium carbonate CaCO3 as found in limestone. Some other compound?

When you read or hear in the mass media (or anywhere else) of carbon emissions from fossil fuel burning, the compound carbon dioxide is being referred to, not elemental carbon.

Anyway, elemental carbon is a solid at temperatures below 3000 C. Diamonds are a form of elemental carbon. So is graphite. Buckyballs and graphene and carbon fibers too. Charcoal is mostly "amorphous" carbon and has many uses. And of course elemental carbon makes an excellent solid fuel.

Solid carbon dioxide? That is usually called "dry ice." Turns to gas at about minus 75 degrees C (at atmospheric pressure.)

Question: What is your knowledge of chemistry?
Many of the answers to your questions in this and other threads would have been touched on in a high-school chemistry course. Or are easily looked up online.

Ok so CO2 is the stuff we are talking about. Why cant we capture the stuff and make diamonds No that wont work the rich people wont like that. From the forum so far I get the feeling most don't oppose the CO2 from Coal power. If so why are we calling for all to be closed. Maybe its just the Muppet Governments like Australia's that has a shock reaction as to how bad it is and we have our heads in the sand.

I think he means elemental carbon and that he has no idea of chemistry at all.

...At the moment there are claims by 2 different companies that they can remove carbon dioxide out of the air for $200 and $600 a metric tonne. In order for it to be commercially feasible the cost needs to be about $100 a metric tonne.
..You might find this an interesting read;

Thanks James was an interesting read. The more I read the more I think we should be focusing at Geosphere Level. Some of the Air Extraction devices maybe the short term band aid solution but we need a massive global effort and lets face it we cant even agree on politics how will we ever resolve Greenhouse Emissions? Living in Asia I see every day pollution on a scale the west just don't understand. China, Bangladesh, Sri Lanka, India, Pakistan and many more are spewing out air pollution you can see visually its that bad.

So asking a question about something that I learnt more than 40 years ago is saying nothing has changed. Hmm beg to differ. Too many Pre-Madonna's in Education claiming to be scholars and wonder why they are disregarded by the populist. To share your knowledge and open a discussion on a subject your claiming hasn't changed only proved your bias in the subject. If your so brilliant why haven't you solved the problem?
Oh maybe because your a protagonist and not a problem solver.

perhaps the use with the largest potential (in terms of gigaton) is carbon fiber, or alternatively plastic. carbon fiber reinforcing resin or ultra-high molecular weight polyethylene could be used as structural materials for buildings or transport vehicles (cars, trucks, planes). IF you could substitute cement and steel in buildings and transport with carbon-based materials, you could have about 3 Gt/annum of market potential.

How do we know the pre-industrial temperature and CO2 measurements? Neither were being monitored on a global scale at the time. Thermometers with the precision to measure temperature to a usable level, for the 1 degree Celsius per century estimate rise, weren't available for a couple hundred years later. CO2 was monitored until 1958, hardly on a global scale, on the side of an active volcano to boot, Mauna Loa. Basically, global warming was declared, before measurements and data to support it even existed, everything is based on proxies, analogs, and computer simulations. It's science fiction, and a video game.

Uses for carbon... How about a live solution? All life on this planet is based on carbon molecules. That carbon comes exclusively from CO2. Nothing digests or metabolizes solid carbon. Plants are the only living thing that pulls CO2 from the atmosphere, everything else gets carbon from the plants, one way or another. Look up CO2 augmentation for greenhouses, to see the real life effect of CO2 on plant growth and development. No need to take my word for it, a common practice for decades. Your 410 ppm is about 20% of the ideal CO2 level. Oddly enough, adding 1000 ppm to a greenhouse, doesn't raise the temperature either, no cooling required...

Theory goes that CO2 up temp up right?

What about if CO2 doesn't go up? Could/would the temp go up? Have you EVER heard that discussed? Don't you think it would be important to parse out CO2's impact form other factors?

The data you're referencing I think is reflected below right?:


And now here:


I would argue that U.S. temperature readings are more accurate than global temp readings because it was more actively recorded since 1880 than other locations. Let's assume that the temp readings are accurate enough to be of some use.

The US had very warm weather in the 1930s and you can see the evidence here from the EPA:


But as the CO2 history shows CO2 levels didn't really increase up to 1930. They did increase after that but temperatures fell. In fact in the 1970s there were articles written about a coming ice age.

So being critical of an exclusive focus on CO2 is useful because we need to have perspective on what's really going on IF that's within our ability.

I hope you'll at least agree it's not a simple cause/effect story in the data that is presented. A high school class would be pretty confused hearing the theory and then looking at these charts (which are Nasa, EPA, standard data thrown around).
