Since we're swimming in the realm of opinion: it's not selfish precisely because the issues you raise are all solvable and I choose to believe they will be solved. There has been no time in human history where one could not have raised equally valid issues, and then proclaim nobody should have children because of said issues.

In fact, today is the best time in history to have children (or in your phrasing, today is the least selfish time in human history to have a child). Humanity is radically more capable of supporting another baby now than at any other time. It isn't even remotely a close contest.

Questions of resources? No it's not. We're drowning in food, take a look at the massive boom in Russian wheat production as one example. Global food potential is far beyond where we're at now, likely by a magnitude. We don't know what to do with it all. And that's before we take it up another level and move to drastically more productive food output methods, including indoor farming, AI + robotics, growing meat, better information management & knowledge globally, etc; and that's while we're still acting very inefficient with our existing food (throwing vast amounts of it away). Merely developing Africa's food potential alone will feed billions more people.

Maybe you're thinking energy? Have you seen the massive boom in solar and wind? That's going to get a lot more massive yet. We're intentionally under-developing nuclear, because right now it doesn't look like we're going to need it. Renewables are making up the majority of all new energy production globally, that tilt is going to get more extreme by the year. If the world had to do it, we could collectively throw trillions of dollars at nuclear immediately, and boost global energy output substantially within a few decades.

To date, humanity is batting a thousand at not going extinct due to challenges. Climate change will be no different.
