> in this case deforestation outweighs reforestation by a huge margin.

This is not remotely what is suggested by numerous studies. You can see in Africa for example deforestation and regrowth (in other areas) as whole make a balanced picture of tree biomass: https://www.nature.com/articles/s41467-018-05386-z

Of course there are countries like Brazil where deforestation is happening at a faster pace (mainly driven by poverty and poor agricultural efficiency in the Amazon), but that does not mean the whole world is following the same trend. That's alarmism.
