Whats harmful about carbon dioxide emissions, CO2?
It’s not so much that carbon dioxide is harmful. It’s that too much carbon dioxide is harmful. What are green house gases? Many chemical compounds found in the Earths atmosphere, such as carbon dioxide, act as greenhouse gases. These gases allow sunlight to enter the atmosphere freely but trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earths surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earths surface roughly constant. Many gases exhibit these greenhouse properties. Some of them occur in nature (water vapor, carbon dioxide, methane, and nitrous oxide), while others are exclusively human-made (like gases used for aerosols). Why are atmospheric levels increasing? Levels of several important greenhouse gases have increased by about 25 percent since large-scale industrialization began around 150 years ago. During the past 20 years, about three-quarters of human-made carbon dioxide
