It is the the ratio of reflected power to total incident power
Enhanced greenhouse effect
It is the increase in greenhouse effect as a result of human activity
Global warming
It is the increase in Earth's mean temperature
Greenhouse effect
It is the process by which atmospheric gases absorb infrared radiation emitted from Earth and re-emit them back down to warm the atmosphere and Earth's surface
