description: cellulose
basis: Early-millennium climate was marked by relatively warm winters and high growth season relative humidity, especially ~AD 1100a€“1250, followed by the onset of cooler and drier conditions in the early 1500s. Winter temperatures apparently attained 20th century levels by about AD 1800, while relatively low growth season humidity persisted until
about AD 1900.
