Increased greenhouse gases lead to a rise in global average temperature due to the greenhouse effect. This effect traps heat in the atmosphere, resulting in various environmental changes. Key examples include severe weather events and rising sea levels. ;
The global average temperature increases when there are more greenhouse gases in the atmosphere due to the greenhouse effect, which traps heat. Human activities have contributed to higher concentrations of these gases, leading to significant climate changes. The correct answer is A. The temperature increases.
