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.

“There is much to be said against the climate on the coast of British Columbia and Alaska; yet, I believe that the scenery of one good day will compensate the tourists who will go there in increasing numbers.”

“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
“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)
