| Crono said: "Other processes, like biological ones, only recycle the carbon in biosphere, they don't add it. So if you're saying volcanoes didin't add the CO2, then it's humans." You can't take natural causes out of the cycle. Its no wonder you think we're all going to drown in ice cap water or something, you have no idea how to think logically. If the total amount of CO2 in the atmosphere is equal to an arbitrary number like 1000, but non-natural sources account for 10 of it, and humans account for 6 of that, you could say that humans are the biggest contributor of non-natural CO2 in the atmosphere. Thats peachy. It doesn't freaking matter though because 6 out of 1000 is insignificant to the whole, and thus insiginificant to the TOTAL greenhouse effect caused by CO2. |
I haven't said anything about drowning in ice cap water. 30% addition of CO2 in the atmosphere is significant and humans have caused that. In pre-industrial times CO2 levels were about 280 ppmv, now they're about 380 ppmv.
What you don't seem to understand is that the natural cycle doesn't add the amount of carbon dioxide in the atmosphere. An analogy: there's a pool in your cellar and it's half full. You also have a pump that drains water from the pool, attached to a hose that squirts the exact amonut of water that is drained back to the pool. We call that natural addition of water. Then there's Dude X who brings a bucket of water every hour to the pool. Are you going to say that the pool won't ever get filled with water because the addition of the Dude X is so insignificant compared to the natural addition?
