Question: How can increased carbon dioxide uptake, or sequestration, by global forests change climate? Need Assignment Help? View Available Hint(s)for Part E Increases in forest cover lead to increased flooding. Increased carbon sequestration leads to increased tsunami frequency. Carbon dioxide uptake by forests led to the end of the Pleistocene epoch. Net global forest growth removes carbon dioxide from the atmosphere, thus cooling the earth's climate. As forests expand, carbon dioxide is lost to the atmosphere.
