Which phenomenon is responsible for the enhanced greenhouse effect?

The enhanced greenhouse effect primarily results from human activities that increase greenhouse gas emissions, such as burning fossil fuels, deforestation, and industrial processes. These actions release additional carbon dioxide, methane, and nitrous oxide into the atmosphere, which trap more heat than naturally occurring gases, leading to a rise in global temperatures.

This phenomenon differs from the natural greenhouse effect, which is vital for maintaining Earth’s temperature by trapping some of the sun's energy. The enhanced greenhouse effect intensifies this process beyond normal levels, contributing to climate change and its associated environmental impacts.

In contrast, natural changes in atmospheric gases, changes in solar energy output, and variations in the albedo effect do not originate from human activities and do not account for the observed rapid increases in global temperatures linked to industrialization and increased fossil fuel use.
