1. I don't have the equipment to take co2 readings, and over a period of time, so no idea.
2. Humans do contribute to co2 and many other things, just like many other things also contribute to co2.
3. Again, I don't have the equipment to take accurate temperature readings, and over a period of time, so no idea.
4. No idea.
5. No idea.
6. No idea, just a science theory, like all theories.
7. Just because of mankind? No.
Point 8 should be, "Do you believe in the doom and gloom alarmists predict when co2, sea level etc.. is way way less compared to historic readings?". My answer would be no.
Point 9 should be, "Do you think there's a law on how fast or how slow a geological event can happen, or the rise and fall of such things as co2?". My answer is no.
What readings did you get from your instruments?
