Global warming will cause rising global temperatures and sea levels, glacial retreat, more flooding and drought, and changes to agricultural yields and animal habitats. One of the main causes is pollution from vehicles, factories, and CFC gases from products like hairsprays, which also damages the ozone layer. The Kyoto Protocol aims to reduce CO2 emissions by 80% globally, but the United States has not ratified it due to concerns it would negatively impact economic growth.
