Table 1 Statistically downscaled CMIP5 multi-model average mean (and standard deviation, in brackets) projected increases in maximum and minimum temperature (°C) and annual precipitation (%) in the mid- (2022–2060) and late- (2062–2100) 21st century for the Rio Santa and Vilcanota-Urubamba regions, compared to the control period (1980–2018).
