I'm surprised by how different a picture this paints than what Jesse Ausubel presented at a Seminar About Long-term Thinking, a few months ago. His presentation was surprising then, inasmuch as it seemed to me, at the time, to be 'common sense' that we're destroying ever more of the world's forest, daily, and burning through all our natural resources at an untenable rate. He argued that human productivity had, through tech developments, decoupled from resource use; that we're producing exponentially more crops on far less acreage, using far less water, fertilizer and pesticides, per unit of crop, than ever before; that much of the world has already reached 'peak timber', as our demand for paper and wooden building materials diminishes, and we may be at 'peak car' around now--and that, generally, we would likely be continuing in a direction of less resource exploitation per capita, in the near future.
Anyway, reverting to my earlier 'common sense', it seems completely believable that the Amazon is regularly losing more forest than North America and Europe could possibly be returning to forest... I haven't read thru the CSM story yet, so I'm not sure where else their conclusions may diverge, but give the Ausubel talk a listen, if you can tolerate even a whisper of optimism about the future.
