Climate
During the late Pleistocene period, the climate began a dramatic change. It is unknown how and why exactly the climate changed, but scientists speculate that the Earth’s orbit around the sun changed, leading to an evident increase in the amount of sunlight exposed to the planet. As the Pleistocene period gave way to the Paleo-Indian period, so did the harsh winter climates give way to a suitable warm climate. Strong evidence for the warm climate is the many warm-weather plants that have been found during excavations at Barton Gulch.

Famous quotes containing the word climate:
“Is not their climate foggy, raw, and dull,
On whom, as in despite, the sun looks pale,
Killing their fruit with frowns?”
—William Shakespeare (1564–1616)
“The question of place and climate is most closely related to the question of nutrition. Nobody is free to live everywhere; and whoever has to solve great problems that challenge all his strength actually has a very restricted choice in this matter. The influence of climate on our metabolism, its retardation, its acceleration, goes so far that a mistaken choice of place and climate can not only estrange a man from his task but can actually keep it from him: he never gets to see it.”
—Friedrich Nietzsche (1844–1900)
“If often he was wrong and at times absurd,
To us he is no more a person
Now but a whole climate of opinion.”
—W.H. (Wystan Hugh)
