The world is getting hotter, and we are getting close to a point where the new fire is too much. We have made some changes to use power better and are getting closer to not putting out as much bad air that warms the world, but we still have a long way to go to stop it completely. Because of this, some people are thinking about really big ideas to make the world hurt less from this new fire. These ideas can not fix the bottom cause problem, but they might make things less bad for a while.
One idea has to do with the white soft stuff in the sky—sky water. Sky water is very important for keeping the world air and ground the right kind of warm. If we did not have sky water, the world would be way, way hotter! But not all types of sky water cool things down. Some high, fine sky water made of ice, also called high sky water, do something totally different. They work like the glass in a hot car, making the world warmer. If we could clear the world of all high sky water, it could make the world cooler—even cooler than it was before we started putting bad air into the sky.
Of course, we can not just take all high sky water away, but some people are thinking about whether we can change how sky water is made so it does not warm the world so much. This idea might work best in places where other ways of cooling the world do not work well, like at night or in very cold places.
The problem is, we do not really understand high sky water very well. They are one of the hardest parts of the sky to understand, so trying to change them is really, really hard. For now, this idea is something we can only try out on computers or in small sky water rooms. It might never work in real life, but thinking about it can help us learn more about how the world works and how we can take care of it.
