Is the greenhouse effect man-made?

The natural greenhouse effect is not man-made. The

earth's carbon and water cycles keep enough greenhouse gas in the

atmosphere to warm the planet so that life can exist. This has

happened for millions of years.

The enhanced greenhouse effect is man-made. By burning

fossil fuels and by deforestation we have been adding extra

greenhouse gases to the atmosphere since the beginning of the

Industrial Age (around 1750).
