If it weren't for greenhouses gases, what would be the temperature of the earth be like?

earth's average temperature would be near 0°F (or -18°C)

explanation:

greenhouse gases in the air, mainly carbon dioxide, methane, and water vapor, trap radiation from the Sun and act as a thermal blanket around the planet. without the greenhouse effect, earth would have an average temperature of -18 °C and be covered in ice. life as we know it would not be able to survive.

good luck :)

hopefully this helps

have a great day !!
