 And I want to show you one more thing that can happen with the atmosphere. And that's changing the number of clouds. So I've reset everything else, but I've added in some clouds. And what you see is once we've got some clouds in the atmosphere, some of the visible light actually gets reflected off of those clouds and never makes it to the ground. So clouds can have a cooling effect. Clouds can also absorb some of the infrared photons and redirect them downwards, however. So they kind of balance out a little bit. It's a little bit more difficult to look at the effect of that. But it is an effect that needs to be taken into account.
