It's actually incredibly simple physics.
1. Do humans put carbon dioxide into the air?
Yes. That's undeniable.
2. How does the planet maintain temperature?
Through a balance. Heat from the Sun is absorbed and much bounces off into space. This is undeniable.
3. Does carbon dioxide alter that balance?
Yes. Carbon dioxide absorbs the energy that was bouncing back into space and reemits it back towards the ground which heats the plane. This is undeniable.
I don't see how there's an argument here. None of the above is above primary school level science.
I don't think I suggested any of the above was false. It doesn't address anything I said though.
But to address your points directly, something others on this thread will do well to learn how to do.
1. Is correct. Humans produce more Co2 than would exist absent their production.
2. 2 is a bit of a simplification. The planet 'maintains' (I guess we can say that in respect to a short period) temperature via a multitude of processes, some of which we've theorized about, others we have a handle on, and some are oblivious to us. So stating the little part we know of and declaring it undeniable, is incomplete.
The little we know is undeniable. The rest, well we are clueless about and theorizing, observating and studying
3 also is like 2. Yes Co2 can and does increase warming. But by how much? The historical correlation between Co2 emissions and a warming of the planet is very flimsy. And this isn't because Co2 doesn't cause or have a greenhouse effect. But rather because there are other factors at play.
So like I said at the top, nothing you've responded with is at issue. At a simple level there are 4 separate points here:
1. Is the planet warming? Absolutely! Albeit at a slower rate the last 30 years compared to the prior 100.
2. Is the warming due too humans. Yes. .Partly due Co2 amongst other things so.
3. Is this going to become a crisis. We don't know. It May or may not. But what we do know is that models are awful at predicting future. and the Earth's .
4. Must we all band together and do something? Like those in government's around the world want? Like join treaties that puport to do things, that even the Scientist believe most of these things won't help.
That was my point.
