Coincident with the abrupt cooling and hydrological changes of ~ 5,200 yr BP, archaeological studies support a general pattern of abandoned Neolithic human settlements in several areas, including the Andes and the entire Eastern Mediterranean, indicating a widespread climatic crisis that marks the transition from the Chalcolithic to the early Bronze Age (Weninger et al., 2009).

Although these hydrological changes could potentially increase soil water availability in previously snow - covered regions during the cool low - ET season (34), this effect would likely be outweighed by the influence of warming temperatures (and decreased runoff) during the warm high - ET season (36, 38), as well as by the increasing occurrence of consecutive years with low precipitation and high temperature (Fig. 4A).

Human activities are exerting pressure on the environment with consequences such as global climate change, disruption of the hydrological cycle and impacts on water catchments.

When done so, proxy records and climate models indicate that the response to past global warming was profound, with evidence for global reorganisation of the hydrological cycle and profound local increases and decreases in rainfall; combined with elevated temperatures and terrestrial vegetation change, this appears to often result in warming - enhanced soil organic matter oxidation, chemical weathering and nutrient cycling.
