Given the island's southern latitude, the climatic effects of the Little Ice Age (about 1650 to 1850) may have exacerbated deforestation, although this remains speculative. Many researchers point to the climatic downtrend caused by the Little Ice Age as a contributing factor to resource stress and to the palm tree's disappearance. Experts, however, do not agree on when the island's palms became extinct.
