> Don't plants require carbon dioxide to grow?

Yes, but they also require other things to grow, so the scaling of their growth with rapidly increasing atmospheric CO2 concentration isn't as impressive as some people imagine, and it's only been empirically demonstrated in the short term. As far as I've read, the main uncertainty as to what happens in the medium-long term relates to how much nitrogen is available in the soil, and how the nitrogen-fixing topsoil ecosystem adapts. If it can thrive in such a way as to fix more nitrogen, that could lead to further plant growth. But it's also plausible that the rapid shift in the environment disrupts that system and leads to a regression in plant growth rates.

And all of that assumes that unseasonably warm/cold temperatures from changing weather patterns, drought or flooding from changing weather patterns, increased wildfires from changing weather patterns etc doesn't kill off many species in an area.
