>You still didn't answer the question, what exactly model you refer to? Good question. Which of the many non-working models would you like to discuss. Why don't we start at the IPCC? >In fact, no one has been able to show a working model of Earth that doesn't show a warming due to CO2. Which isn't surprising at all, given no one has been able to show a working model of Earth. >If you're young, I think eventually you're going to find that whether the rate of warming is 0.1 degree per decade or 0.2 degree per decade doesn't matter too much. Either way, it's too fast so it will cause mass extinction (and problems for agriculture), and either way, the new steady state temperature is driven by the amount of CO2 we emit. There's no way you can know that. CO2 may be completely dominated by other factors. In any event, I'm not young, so none of this matters to me on a personal level.

I am not sure, at this point, if you are just trolling. Every model has a certain limits, but it doesn't mean it is "not working". If you actually knew history (I always recommend https://www.aip.org/history/climate/index.htm https://www.aip.org/history/climate/index.htm) it is a remarkable achievement that we can model climate at all. > There's no way you can know that. CO2 may be completely dominated by other factors. Sorry, this is just trolling. Of course, in the same sense, we cannot predict the path of the Earth around the Sun because what if an unknown dominating factor comes to its path? When creating a model, we simply try to account for every important factor we know of. And given that the predictions are quite accurate (look at Lindzen comparison!), we probably know of all the important ones.
