Mesoamerica

An analysis of several climate proxies undertaken in Mexico's Yucatán Peninsula, which was linked by its authors to Maya and Aztec chronicles relating periods of cold and drought, supports the existence of the Little Ice Age in the region.

Another study conducted in several sites in Mesoamerica like Los Tuxtlas and Lake Pompal in Veracruz, Mexico show a decrease in human activity in the area during the Little Ice Age. That was proven by studying charcoal fragments and the amount of maize pollen taken from sedimentary samples by using a nonrotatory piston corer. The samples also showed volcanic activity which caused forest regeneration between 650 and 800. The instances of volcanic activity near Lake Pompal indicate varying temperatures, not a continuous coldness, during the Little Ice Age in Mesoamerica.
