There's a word for this: "antinatalism".

The idea that it could be morally or ethically better to not have children feels like further in-depth thought out examining the specifics in attempt for a rational and non-emotional answer would yield a pretty strong "no". It is a vastly personal decision and I would encourage you to answer this for yourself personally and to try to look for the arguments of those who are saying the opposite of your close social friends (if they are saying "no", then look for people saying "yes", if they are saying "yes", look for people who are saying "no").
The arguments that come to my mind:
1. The world has always been filled with an amount of danger to offspring, this is not more existential than it has been in the past (though it's often hyperbolized to be).
2. There are vast amounts of anecdotal stories about children who were "almost not born" (failed abortion, doctors or parents said it would be too hard, etc.) because of a parents decision who ended up having a hugely beneficial and/or great life.
3. There is a stronger effort now than ever before on correcting climate change. There are more opportunities than there ever have to make a difference. Your child could be one of these people.
4. I have seen no science that an additional child or children is going to inherently negatively increase climate change, which means having a motivated parent to better the world has a huge potential upside for the climate and low downside.

An additional side, I would use any of amount of logic of "should have a child" either. If you don't want a child, I do not think you should have a child. A child needs love and compassion from its parents.
