Of all the seasons, winter is the most conducive to the great art of dormancy. This art requires an appreciation of semi-consciousness: the beautiful and necessary prelude to sleep - a special pleasure in itself that is all too often neglected, under-valued or looked down upon.

We see evidence that lakes and forests and wetlands can have different equilibria - so you have a savanna system that may be stable and thriving, but it can also tip over and become an arid steppe if pushed too far by warming, land degradation, and biodiversity loss.
