Holy moly! Holes may hold the answers to avoiding climatic extremes

Hot and dry areas in southern Africa, like the Kalahari, are predicted to get even hotter and drier with climate change. That will pose a massive challenge for an ecosystem with organisms already living on the extreme edge of what is survivable. Without enough water, plants are likely to die, and without plants at the base of the food chain, the whole system will struggle to survive. Yet, if both plants and animals can find small areas in their environment that gather moisture and provide shelter from harsh radiation, there is hope that they may be able to cope, even when the large-scale climate is not in their favour.
