how would earth be different without the greenhouse effect
Without the greenhouse effect, Earth would be much colder and unable to support life as we know it. The greenhouse effect is a natural process that helps trap heat from the sun in the Earth's atmosphere, preventing it from escaping back into space. This makes the Earth's surface warmer than it would be otherwise.
If the greenhouse effect did not exist, the Earth's average temperature would be around -18 degrees Celsius, compared to the current average temperature of around 15 degrees Celsius. This would make the planet too cold for liquid water to exist, which is essential for supporting life.
Without the greenhouse effect, the Earth's atmosphere would also be very different. Greenhouse gases such as carbon dioxide, methane, and water vapor help regulate the Earth's temperature by trapping heat in the atmosphere. Without these gases, the Earth's atmosphere would be much thinner and unable to maintain a stable temperature.
Overall, without the greenhouse effect, Earth would be a cold, inhospitable planet that would likely not be able to support the diverse range of life that currently exists.
