  • Pretty well frozen over. The average surface temperature would be about -4 degrees Fahrenheit if there were no greenhouse effect.
  • In addition, since water vapor is the most abundant greenhouse gas, the world would also be a very dry place. I guess it would be a lot like Mars, very cold and lifeless.
  • Earth's atmosphere naturally has greenhouse gases in it. Without them Earth would only be heated by its core and the rays of the sun. Those rays would warm us during the day, but at night all the heat would be lost back into space.
  • Greenhouse gases insulate Earth, comparable with a blanket. Without that 'blanket', the average temperature on Earth would drop to about -18°C (0°F) and life would almost be impossible.
  • All heat from the sun hitting the earth would be reflected back out to space and most of the earth would experience ice age conditions.
  • The Green House effect is important because there is a kind of gas that forms a "blanket" around Earth that holds heat in the atmosphere and keeps Earth's atmosphere at a temperature that is comfortable for most living things. So without it the temperature would go down to 50 degrees Fahrenheit (32 degrees Celsius colder than it is).

How cold would the earth be without greenhouse gases?

The earth would not be noticeably colder. What greenhouse gases dois they hold in the heat, causeing the earth to be hotter notcolder, that's why we have increased tornados, a

What would happen without the greenhouse effect?

Without any of the greenhouse gases that help keep the earth warm, global average temperatures would be some thirty degrees colder. Heat would be lost rapidly at night, making

What effect do greenhouse gases have on Earth?

The greenhouse effect is the process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases,and is re-radiated in all directions.Since

Compare Greenhouse gases with the Greenhouse Effect?

A greenhouse gas is a gas in the atmosphere that takes in andreleases radiation. The greenhouse effect is more of a process inwhich radiation is emitted in different direction

Why would the earth freeze without the greenhouse effect?

The earth's carbon and water cycles move carbon dioxide and water vapour in and out of the atmosphere. This means that there are just enough of these greenhouse gases to suppo

What would happen to the earth with out the greenhouse effect?

The earth would become very cold and life would cease to exist. A natural greenhouse effect is necessary to keep the earth warm enough for life. . However, since we started s

How do greenhouse gases cause the greenhouse effect?

Briefly: Greenhouse gases capture heat rising from the earth. This warms the atmosphere and also the earth. In more detail: The Earth receives energy from the Sun mostl

How do scientists know what earths temperature would be without greenhouse gases?

Sampling trapped gas bubbles in ice cores gives both historical levels of greenhouse gasses and indirectly by various isotope ratios corresponding historical temperatures. By

What effect do greenhouse gases have on the the greenhouse effect?

Greenhouse gases are the cause of Greenhouse effect.The greenhouse gases which include CO 2 , Methane etc. trap the heat in the Earth's atmosphere and don't allow it to escape

Why without greenhouse effect earth would freeze?

OK, It wont freeze. Earth has atmospheres which kind of keep SOME heat in but still releasing extra. The greenhouse effect wont freeze earth the less greenhouse emissions th
