Question

Without the greenhouse effect, Earth would

Answer 1

be significantly colder. The greenhouse effect is a natural process that traps heat in the Earth's atmosphere, allowing the planet to maintain a relatively stable and habitable temperature. Without this effect, the Earth's surface would lose most of its heat energy to space, leading to extremely cold temperatures. The average surface temperature of the Earth would drop from about 14 degrees Celsius (57 degrees Fahrenheit) to around -18 degrees Celsius (-0.4 degrees Fahrenheit), which is cold enough to sustain permanent ice cover and potentially render the planet uninhabitable for most forms of life.
