There are debates on the start date and time periods of Little Ice Age's effects. Most scholars agree on categorizing the Little Ice Age period into 3 distinct cold periods. 1458–1552, 1600–1720, and 1840–1880. According to data from the National Oceanic and Atmospheric Administration, the Eastern Monsoon area of China was the earliest to experience the effects of Little Ice Age from 1560–1709. In the Western region of China surrounding the Tibetan Plateau, the effects of Little Ice Age lagged behind the Eastern region, with significant cold periods between 1620 and 1749.
