I heard, the climate related "CO2 fertilization" leads to increased growth in trees. However, especially on mountain slopes, these trees have a lower strength and tend to break more easily in storms. The breakage in softer woods in turn promotes things like wind erosion and fires. I think this is somewhat plausible, since the "winter side" of a wood ring is the harder bit and the ratio of hard to soft wood may change due to increased summer growth. Iceland is the prime example of a place, which lost its trees a bit - and then lost its trees for real, as a consequence. That is, because of wind erosion after humans started cutting down most of the island's forests for lumber. Thanks, for coming to my TED talk.
