Since AR5, the number of studies of changes in phenology  has increased substantially, aided by advances in remote sensing . Phenological studies have documented particularly consistent conclusions on responses of plants and animals to warming, including the advancement of spring events and the lengthening of growing seasons in temperate regions    . In the Tropics, by contrast, changes in precipitation have more strongly influenced animal phenology than have temperature changes . A meta-analysis compared observed phenological advances in birds with expectations due to warming local climates, and concluded
