If your house was flooded, you wouldn't ask what the water was or where it came from, would you?
The real point here is that no one has a solution to remove the excess CO2 and only add back the right amount; yet they want to run the show at our cost.
Your assuming that we have excess CO2 and need to decrease.
If you can give me daily CO2 readings for the last 2 billion years, then we can make a determination if CO2 levels are high, low or part of a cycle.
If your house is flooded, you should ask where it came from. Is it raining? If no is the answer, you probably have a water coming from your own pipes and need to turn the water off.
If the flooding if coming from rain, there isn't much you can do until it stops.
