Atmospheric Greenhouse Effects

Atmospheric Greenhouse effects make Earth’s surface warmer. Carbon dioxide contributes most (55-60%) to the anthropogenic greenhouse effect, and methane is a distant second (16%). The earth’s “greenhouse effect” is what makes this planet suitable for life as we know it. The earth’s atmosphere contains trace gases, some of which absorb heat. These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as “greenhouse gases.”
