RE: Environmental Impacts - Concrete

We live in an environment where there is a deficiency of carbon dioxide in the atmosphere. At 700 parts per million we would have an optimum for plant growth. This is the amount they use in greenhouses. As we get toward that optimum plants create a negative feedback as they grow more and use up carbon dioxide as part of photosynthesis. Basically the carbon dioxide could drop suddenly should we stop creating carbon dioxide. That would be bad.
My country exists due to global warming. Oh Canada There is a lot of uninhabitable land in Northern Canada, Europe and Asia due to permafrost. I guess the fact that Canda isn't totally under ice is not because of human activity. It's a bit of a delusion of grandeur we are exposed to by the lamestream media to think so.
How can I use concrete to create more carbon dioxide than normal?
I'm not certain that concrete production would be the best option to just generate carbon dioxide alone. Not many production methods only produce those compounds we desire. It usually comes as a byproduct along with many other undesirable substances.
Coal Power production, for instance, gives us the much-needed energy society consumes, but generates toxic gases and lingering radioactivity we can do without.
Nuclear Power, on the other hand, gives us carbon-free energy albeit at the expense of radioactive waste we can't handle for thousands of years.
To generate the level of CO2 you feel you require would, unfortunately, draw the ire of global environmentalists. I don't know that there's anything you can do to achieve the results you desire.
I tell my students that I would rather live in a greenhouse than an icebox.
And that anyone who says "the Science is settled" in relation to any issue whatsoever has no clue what the word "science" truly means.
Make of that what you will, I guess.
