Do we really know the impact of forests on climate changes?

Today, I have read an interesting article about forests and their role in climate changes. I think that the impact of albedo changes and its relation to forest cover is discussed very professionally, and I have learned a lot about it. Three key conclusions, I've made after reading this recently published article in Nature.

1. It seems the debate is still open (as always have been), and we cannot say many things about forests and climate change with certainty.
2. We shouldn't also generalize results of small experiments and/or extrapolate their results to the whole world, same as, we shouldn't always believe models that scientists apply, as these models have many assumptions in the background. Personally, I think we should always be skeptic, and see that on this planet nothing is white or black, and that the world is more complex than one could have thought. In other words, we should not frame this planet in artificial policies that apply to global scale, as such policies will never meet local condition constraints and expectations. Diversity over sameness.
3. For me, the take-home message is that under certain conditions, forests are beneficial for climate change mitigation, but under another ones are not. Thus, we should explore all possibilities where to plant trees, what species, at what density etc. And this is the key role of science, i.e. to build knowledge, monitor it, and apply it for our human purposes. The problem starts when scientific knowledge meets political aspirations, generalization and ignorance.
