A Question Please
Would anyone know how much carbon dioxide there has to be in the atmosphere to give people a sense of suffication, or at the least some lightheadedness? What part per million would cause this?
What is the amount at this time?
My understanding is carbon dioxide is heavy so wouldn't symptoms innitially show in populations in lower areas? On a planetwide scale at some point soon if not already. I mean, given the publication of recent findings on greenhouse gas level increases. I'm thinking that I should be more alarmed than I presently feel and perhaps I should some rebreather equipment.
I'd hate to think I'd just lie down and go to sleep concerning the issue.
