be unable to sustain life.
The greenhouse effect is critical for maintaining the Earth's climate within a range that is conducive to life as we know it. Greenhouse gases such as carbon dioxide, methane, and water vapor trap some of the heat that would otherwise escape into space, keeping our planet warm enough to support ecosystems and the water cycle. Without the greenhouse effect, the Earth's average surface temperature would be significantly colder, making it difficult for current life forms to survive. Some estimates suggest that the average global temperature would be about -18°C (0°F), compared to the current average of roughly 14°C (57°F).
