Sure that's kind of my point. The larger the scale, the harder it is to solve such problems. People tend to care first about themselves and their kids, then other family, then about people they interact with regularly. The less they are related or interact with you on a regular basis, the less you prioritize their well being. This is human nature, and easily explained by Darwinian evolution.

Climate change is inherently large scale. There's nothing that will change that.

We can change the equation only by large scale "contracts" and the like. That generally means governments. For instance, we can vote for representatives that make laws that limit emissions from factories and vehicles, and make treaties with other countries. Those things are not subject to tragedy of the commons.

I am not advocating for "messing with the atmosphere" in this sense, but I'm also not rejecting it outright. We are already messing with the atmosphere on a large scale, due to billions of individual decisions driven each one of those individuals' self-interest. If you are going to mess with it, I'd rather it done based on a controlled methodology based on science.
