The greenhouse effect is natural It is important for life on Earth Without the greenhouse effect, the Earth's average temperature would be around 18 or 19 degrees Celsius (0 or 1 degree Fahrenheit) Earth would be locked in an ice age Because of the greenhouse effect, the Earth's actual average temperature is 14 degrees Celsius (57 degreesIn bright sunshine, the air inside a greenhouse becomes warm The greenhouse glass lets in the sun's light energy and some of its heat energy This heat builds up inside the Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human activitiesIn 19, CO 2 accounted for about 80 percent of all US greenhouse gas emissions from human activities Carbon dioxide is naturally present in the atmosphere as part of the Earth's carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals)
