Wow, people are desperate for good news. Well, this is a July article, and the idea that this "stops" the climate crisis is nonesense.
The treest would remove about 10-15 years worth of emissions over 40-100. Emissions are increasing (in fact, accelerating).
Moreover, that carbon would be removed over 40-100 years, and in that time, none of those trees could be cut, nor could they burn.
Now, it should be done! But it is by no means a way of stopping climate.
Fundamental systemic change is requied.
