In Siberia, it is very cold. It produces Permafrost, which is permanently frozen ground beneath. Scientists believe it’s so cold because of all the methane that is produced. Methane is a colorless, odorless, natural greenhouse gas. A greenhouse gas is a gas that traps the sun’s heat.
The Aral sea is in Kazakhstan and Uzbekistan. The water is a salt-water lake. In 1973, it was a very large lake. Because of climate changes and human changes, it is only a fraction of the size it was in 1960. It is very dry there and central Asia is as well. Central Asia has semiarid and arid regions. This was very critical because the animals around there didn’t have their resources. Pollution also caused this drought. Fertilizer and pesticides, came in and their chemicals killed harmful weeds and insects, and came into it.
