Question

What is it called when the atmosphere traps more heat than normal?

Answer 1

When the atmosphere traps more heat than normal, it is referred to as the "greenhouse effect." This phenomenon occurs when greenhouse gases, such as carbon dioxide, methane, and water vapor, absorb and re-radiate infrared radiation from the Earth's surface, leading to an increase in the planet's average temperature. Enhanced greenhouse effect specifically refers to the intensified warming resulting from increased concentrations of these gases due to human activities, contributing to global warming and climate change.
