I could see more water being useful in earth. Probably a way to fend off climate change in there too.

  You might be right. Earth has plenty of water but not enough in some places. Perhaps an icy asteroid could help, if it was parked in orbit and slowly dropped rain on the deserts. But then the sea levels would rise, and the water vapor would act as a greenhouse gas.

    Ocean levels are going up anyway and that is a problem. It doesn’t seem that climate change is worsening hurricanes directly in Florida. But you better believe a lot of Miami is low lying and storm surges will get wors.pe. My understanding is that almost all the water in small bodies inside Jupiter’s orbit is in Ceres and the amount of water on Ceres is similar to what is on the Earth’s oceans. I think it is better to send people there and grow a population organically as you could reassemble Ceres into more living space than Mars and get people ready for colonization of generic outer solar system and interstellar objects.

      We talk about the ppm of co2 in effect on climate. I was even thinking of releasing additional o2 in that above comment. Or similar -“dissolve“ the carbon in additional atmosphere. But no ideas on secondary effects.

    https://what-if.xkcd.com/ https://what-if.xkcd.com/ >> Could I cool down the Earth by capturing a comet and dropping it in the ocean, like an ice cube in a glass of water? > No. In fact, it's honestly sort of impressive to find a solution that would actively make the problem worse in so many different ways. The short answer is, the falling ice adds about 100x as much heat from the difference in potential energy than it cools.
