Common mistake

Confusing Natural and Enhanced Greenhouse Effect

Students often confuse the natural greenhouse effect with enhanced global warming, thinking they are the same phenomenon.

To fix this, students should focus on understanding that the natural greenhouse effect is essential for maintaining Earth's temperature, while enhanced global warming refers to the additional warming caused by increased greenhouse gas concentrations due to human activities.
