You walk around a European city in southern Europe and Italy or whatever, and you will see fountains all over the place.

They kind of spray out water in a fine mist, which is very, very cooling.

You can have green roofs where you kind of grow plants on your roofs and that can be cooling, that can cool a city.

Or you can paint roofs white to reflect more of the sunlight back into space.

So we have technology to do this and we have natural methods as well.

We just need people to use them.

People haven't really needed them.

There have been efforts to do it.

I think, you know, there are tree-planting schemes and so on, but you need the follow-through.
