So maybe increased climate change is how we can replant the world's lost trees

Short answer - NO.

I read about this story a few days ago upon another site, it pertains to tree's growing in a permafrost area, if you factor that the permafrost will release lots of methane, then this area of increased growth is not as rosy as it seems.

Sure, such stories can be spun in any direction.

Climate change debate can be settled with - do you want clean air and water? Which everybody I've met - says yes - whatever their statistical stance on climate is.

Yeah things are not as simple as it seems. I read a study on irrigation of the Sahara to grow forests, but the change in albedo (reflectivity) from desert sand to dark forest would counteract the benefit of the carbon sequestration and lead to a net temperature increase. I imagine the same holds true for northern areas because snow and ice are extremely reflective. The methane release is just icing on the metaphorical shit cake.
