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:
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
“When we consider how much climate contributes to the happiness of our condition, by the fine sensation it excites, and the productions it is the parent of, we have reason to value highly the accident of birth in such a one as that of Virginia.”
—Thomas Jefferson (1743–1826)
“The climate of Ohio is perfect, considered as the home of an ideal republican people. Climate has much to do with national character.... A climate which permits labor out-of-doors every month in the year and which requires industry to secure comfort—to provide food, shelter, clothing, fuel, etc.—is the very climate which secures the highest civilization.”
—Rutherford Birchard Hayes (1822–1893)
