Does anyone know how many m2 or acres of jungle/forests are needed to offset the carbon footprint of the average American family?

Carbon bound in vegetation eventually ends up back in the atmosphere due to rotting or burning. Carbon footprint = carbon dug out the ground – carbon permanently stored back underground. As long as the latter number is roughly zero, there is no real offsetting.

They do, but only temporarily, unless you permanently prevent it from rotting or burning, i.e. bury it deep in the ground. If that was what were truly after, it would be more effective to stop digging new carbon out of the ground.

In my situation I can't force others to stop digging carbon but I can buy say 1000 hectares somewhere and use them for carbon capture. In that case what would you do?

Perhaps we can change the atmospheric composition in other ways (to offset the greenhouse effect), but I don't see how we can realistically stop growth oriented humanity in the next decades from putting more CO2 into the atmosphere than we or Gaia take out of it.

Would you consider putting some resources towards finding strategies by which a human civilization can survive in a much hotter (but also much greener) world? By 2100, we probably observe 4.5 +/- 1.5 C warming, but it will continue to get warmer for centuries after that.
