16 Greenhouse gases warm the planet Scientists know with virtual certainty that increasing greenhouse gas concentrations tend to warm the planet In computerbased models, rising concentrations of greenhouse gases produce an increase in the average surface temperature of the earth over time1019 Although greenhouse gases make up only about 1 percent of the Earth's atmosphere, they regulate our climate by trapping heat and holding it in a kind of warmair blanket that surrounds the planet Greenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gases Greenhouse gases allow the sun's light to shine onto Earth's surface, and then the gases, such as ozone, trap the heat that reflects back from the surface inside Earth's atmosphere
