The Greenhouse Effect

The Greenhouse effect is the Process in which sunlight emitted from the sun to our planet through our atmosphere. That sunlight then interacts with the planets greenhouse gasses, gasses in the atmosphere which absorbs and emits thermal radiation. These gasses include Carbon Dioxide (CO2), water vapor, and methane. What happens next is the thermal radiation gets trapped within these greenhouse gasses and the planet overall temperature beings to rise. and we get natural occurrences such as these:   

Pictured is what happens to glaciers as the planets temperature goes up.
