Yes, less sorry. Whats the evidence that people will increase the amount of children again? I really dont see such trends, the hole first world is flattening out or shrinking. As for energy, I think that with continuing growth of population, you will have even more urbanisation and that means less energy per person. A New Yorker uses less energy then somebody in a small rual town. The total energy output of the sun can be massivly harvested for energy. We also have nuclear that we could use far more of. We have lots of proven Gas left, and neither coal nor oil is used up. Their are of course a hole bunch of other viable option. Thats before even considering more futuristic tech. Even should the price go up, the market can massivly react to it. Their are so many simple ways to save lots of energy that people just dont bother with right now. As for Climat change, I think the economic predictions on it, are not all that bad. Because of the long time scale we have time to do a hige amount of adoption. Living near the equator will be less habitable, but loving in Canada might be improved. The economic models I have seen trying to account for the cost of adjustment are not actually that high. Admitatly, if you are right that population growth will rise in the rich countries, we might have a problem in the long term bit their are many other problems that are far more worrying.
