Which statement describes how human activities, including releasing greenhouse gases, deforestation, and urbanization, can influence climate?

• Releasing greenhouse gases, deforestation, and urbanization decrease the amount of carbon dioxide in the atmosphere, causing global temperatures to increase.

• Releasing greenhouse gases, deforestation, and urbanization decrease the amount of carbon dioxide in the atmosphere, causing global temperatures to decrease.

• Releasing greenhouse gases, deforestation, and urbanization increase the amount of carbon dioxide in the atmosphere, causing global temperatures to decrease.

• Releasing greenhouse gases, deforestation, and urbanization increase the amount of carbon dioxide in the atmosphere, causing global temperatures to increase.
