ELI5: Explain Like I'm 5

Sea level rise

Sea level rise is when the level of the ocean is getting higher and higher, because the water is heating up and melting the ice on and in the earth. This means that the sea will eventually get so high that it will reach places that are usually on dry land, like beaches and cities. This can be dangerous because it can flood these places and make them unable to be used. So it's important that we find ways to stop the water from getting higher, like reducing the amount of pollution that is causing the water to heat up in the first place.
