This is the desert on which Las Vegas is located, bordered by the Great Basin Desert and the Tehachapi Mountains. The higher the ratio, the less available moisture there is. The single sediment layers are like age rings telling a story of humid and dry periods. This too has an impact on local biodiversity.

But what about cold deserts? MWQ4OTkyZWQ3MzRhOTJkNWFkNGQ5OWU0MTY5N2IzNmRhYTU2MTkwMjliNjc0 Even after these lakes ceased to exist, humans survived for centuries in the desert using alternative methods: nomadic pastoralists herded goats, sheep, or camels to whatever pasturage could be found; sedentary agriculturalists, confined to oases, harnessed their limited water resources to grow crops such as date palms and barley; and specialists (for example, blacksmiths) traded wares with their agriculturalist and pastoralist neighbors.

All of this contributes to soil erosion and an inability for the land to retain water or regrow plants. Imagine flooding a desert half the size of the Sahara. This could double or triple if They enriched levels of CO2 above three 23-meter-diameter plots by about 50%. The region, despite having lush valleys around and between the rivers, had much lower precipitation than Egypt which relied on annual Nile flooding (18). Several other notable facts about the Gibson Desert include the belief that it was the home to the last indigenous tribe to make contact with western civilization (the Pintupi).
