The primary source of green house gas isn't deforestation, it's fossil fuels pulled up out of the ground.
Yes, you can think of trees as solar-powered CO2 crystalization, so more trees, more CO2 removed. The problem though is that this is a temporary solution. When trees die and rot or burn (forest fire), they ultimately release most of that CO2 back into the atmosphere. Even worse, that carbon may be released as methane instead, if it decomposes anaerobicly.
There's only so much biomass the earth can sustain to naturally store carbon. The page you link is correct in that we definitely shouldn't make the problem even worse by reversing what carbon the biomass does store.
But it is in no way the solution to putting carbon we mined out of the earth back into the earth. Well trees as a carbon sequestration did already happen: it just took millions of years for buried biomass to be turned into oil and coal.
I didn’t propose a solution. I simply corrected wrong information presented by the other user. Trees sequester carbon, even if with volatility, as explained in the links.
New research, published in Nature Climate Change and available on Global Forest Watch, found that the world’s forests sequestered about twice as much carbon dioxide as they emitted between 2001 and 2019. In other words, forests provide a “carbon sink” that absorbs a net 7.6 billion metric tonnes of CO2 per year, 1.5 times more carbon than the United States emits annually.
I agree, it’s not a solution.
