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:
“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
“The climate has been described as “ten months winter and two months mighty late in the fall.””
—Administration in the State of Colo, U.S. public relief program (1935-1943)
“A tree is beautiful, but what’s more, it has a right to life; like water, the sun and the stars, it is essential. Life on earth is inconceivable without trees. Forests create climate, climate influences peoples’ character, and so on and so forth. There can be neither civilization nor happiness if forests crash down under the axe, if the climate is harsh and severe, if people are also harsh and severe.... What a terrible future!”
—Anton Pavlovich Chekhov (1860–1904)
