The forecast for global heating disaster is at least 2 billion climate refugees by the end of this century.

I think it will be more, because scientists keep discovering more positive-feedback loops that will make things worse than was previously predicted. The refugees may well end up dead.

The disaster that happens in this century will be just the start. After 2100, things will keep getting worse for thousands of years.

Supporting a baby will get harder and harder as global heating and resource exhaustion bite. We must emphasize the importance of reducing human reproduction.

If you want to take risks with your own life, or about how you will live, you are entitled to. But don't make a baby if it will have to share such risks with you. More children growing up stunted by precarity do not give the world hope — they pull it down.

If you are not in a situation where you can be reasonably confident you can support a baby, you should not make one. Use birth control, and if it does not work, have an abortion.
