The following is opinion and opinion is not worth much. Especially since there are many whose opinions are the opposite of my opinions. 😎
I doubt that we can stop climate change. We might be able to quit exacerbating the situation by reducing the human contribution, but I think climate change will happen regardless of human contribution. There are also possible natural events which can catastrophically increase the rate of climate change.
Sure, it is possible that technology may be able to produce some mitigating products but I don't think that we will be able to do more than reduce the rate of change.
