Sampling trapped gas bubbles in ice cores gives both historical levels of greenhouse gasses and indirectly by various isotope ratios corresponding historical temperatures. By using statistical curve fitting techniques a function of temperature vs. greenhouse gas levels can be determined and thus the temperature for any level calculated.

An alternate technique is to use computer atmospheric modeling on supercomputers. These models are similar to weather models but usually with a courser mesh to do global temperature modeling instead of detailed local weather system modeling.

There will be uncertainty with either technique, but they agree quite well in general.

What would happen to earths atmosphere without the greenhouse effect?

Without the greenhouse effect, Earth's atmosphere would be much colder, making the planet uninhabitable for most forms of life. The greenhouse effect helps trap heat from the sun, maintaining a stable temperature range that supports life as we know it.


How does the increase in carbon dioxide emissions affect the earths natural cycle of temperature cycle?

It raises the temperature and makes it hotter through the greenhouse effect.


How would earths average temperature be different if there were no greenhouse gases in the atmosphere at all.?

If there were no greenhouse gases in the atmosphere, Earth's average temperature would be significantly colder. Greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, helping to keep the planet warm. Without them, Earth's surface would not retain as much heat from the sun, resulting in much lower temperatures.


If the present greenhouse effect trend continues into the year 2100 earths annual average temperature could?

Due to the Greenhouse Effect, Earth's temperature is continually rising. If the trend does not change, the Earth's annual temperature will continue to rise, causing significant ecological problems.


Why is dioxide important to life?

Carbon dioxide acts as a greenhouse gas and retains heat radiation from the sun, which, combined with other greenhouse gases helps to maintain the earths surface temperature. Without the presence of CO2 in the atmosphere, most of the solar radiation would not be retained and thus the surface temperature would be very low and unable to sustain human life.


What is a natural phenomenon that maintains earths temperature range?

The greenhouse effect is a natural phenomenon that maintains Earth's temperature range by trapping heat in the atmosphere. This process allows some of the sun's energy to enter the Earth's atmosphere while preventing some of the heat from escaping back into space.


What controls the climate and protects the Earth from harmful sun?

The atmosphere. The ozone layer absorbs UV radiation, and atmosphere also controls temperature through the greenhouse effect, which allows the earth's temperature to be suitable for life. If there was no greenhouse effect then the earths average temperature would be -14oC instead of the actual 15oC.


What gas increases earths temperature?

Carbon dioxide (CO2) is the primary gas responsible for increasing Earth's temperature through the greenhouse effect. CO2, along with other greenhouse gases, trap heat in the atmosphere, leading to global warming and climate change.

What are the Benefits of Natural Greenhouse Gases?

one pro is that it helps regulate earths temperature, but with fossil fuals which emites greenhouse gases it makes earth get hotter. and that's how you get global warming.
