How Did The Climate Change and Why?
by Josh, Shoko, and Gaby
After the ice-age, climates for river valley civilizations all over the world had some drastic changes. The average year round temperature rose an entire 4-6 degrees. This made life for the villages around the river a lot more comfortable and pleasant. There was also a large increase in the ocean's water level caused by ice melting all around the world. The Asian villages were located near water which was a huge bonus for irrigation since it allowed the farmers to water more crops and produce more food. There were many fossils of shells, fish, and leaves in the museum that hinted that the people by the river made heavy usage of the things in and around the river such as fish and trees near the water's proximity. They found many things in the Tama Museum. In the first section of the museum they found a poster which explained the water level and where things were before the global warming. A good example of this was the early stone age humans who came across the land bridges between the five islands and settled in the Fuchu area of the Yamato Plains around 30,000 B.C. At the time before global warming, the Fuchu area was under shallow ocean water, however, during global warming, the water receded and the humans were able to settle there and and start agricultural society.
