Arid lands transform abruptly as aridity increases

Climate change poses a concrete threat to arid ecosystems, in which water is limited (it rains less than 65% of what is evaporated). These dry ecosystems cover almost half of the terrestrial surface and are predicted to go through increased aridification, which endangers the plants... click to read more
