CO2 isn't the only metric to look at to determine if plants can grow or not in a given environment...

Rainfall pattern/acidity, humidity, average temperatures, extreme temperatures, animals living the the area (providing nutrients through body waste and decomposition), insect population, &c. are all factors, and most of these factors are interdependent

Trees, like animal, migrate, this migration isn't a matter of months, or years, but centuries, since the lifecycles of trees are very long and their locomotion speed is ... limited

If plant kept up with our co2 production we wouldn't get a graph like this when we look at atmospheric co2 level: https://www.climate.gov/sites/default/files/CO2_emissions_vs...

Arguing that "the greenhouse is good because we get more plants" is extremely reductive, and factually wrong

Plants do not sequester enough additional co2 to offset what humans release into atmosphere. But increasing co2 will increase rate of growth of plants provided other limiting factors do not impede growth.

Their locomotion speed isn't limited. We've planted various plants the globe over. It may be naturally limited, but it isn't limited any more.

Flora, fauna and the whole ecology have adapted over tens of thousands of years to the current environment we're in. Sudden massive changes is more likely to lead to mass extinction, adaption due in thousands of years for entirely new species. To massively try to force adaption, will lead to lots of instability and even worse damage than letting nature take its course over a longer timespan.
