And smoking a cigarette won't kill you. Smoking one cigarette a day won't kill you. And most people who smoke don't actually get lung cancer.

But it all catches up with you. Smoking a cigarette a day for a decade is going to cause you to die earlier than if you hadn't. Smoking more, even earlier. Most is not all. Because most people who have lung cancer are smokers. And lung cancer isn't even the only thing. There's emphysema, heart disease, etc that's all related to smoking. And way more likely. But that's all aggregate.

Climate is a lot like that. It's nothing in isolation, it's everything in aggregate.
