...but is bad for humans.
You only need hold your breath for a few seconds and the nervous system will register a tiny imbalance of CO2 in the blood. A miniscule disproportion of CO2 is enough to cause the overwhelming urge to breathe, to bring the balance of CO2 back down.
Increase CO2 in the air by just 1% and you'd be hyperventilating, desperately trying to find air with less CO2.
So won't starve but will suffocate. Brilliant plan.
There is some science. Lots of it.
Some science which confirms creating an imbalance of CO2 is seriously not a good idea and like reckless driving, continuously pumping huge volumes of it into the atmosphere is asking for trouble if nothing else.
So cut some other bullshit schemes, there are plenty of them. Certainly spend time and money to reduce vast levels of CO2 pollution if that's what it takes, even if it can now only mitigate a potential existential harm for future generations.
FC is right. It is an absurd political denial.
But of course, science deniers, especially like Tea Party Pence (omg really!), never do have 'some science'.
Your contribution to this thread does not bear that out.
