olganol [36]

Answer:

The world climate would drastically change.

Explanation:

  • First off, both poles would have rapid expansion, with the freezing of more water near the poles.
  • Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
  • Deserts would expand and the average temperature would rise.
  • Also, many animals would also die out, because of the change in their environments.
  • Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.
