Human activities contribute to the enhanced greenhouse effect by:

An increase in greenhouse gases levels in the atmosphere leads to global warming because:

• They trap more heat in the atmosphere.

• They reduce the amount of sunlight reaching the Earth.

• They increase the Earth's albedo.

• They cause more clouds to form.
