Greenhouse gas simulation

Click on the above image and run the simulation. Note what happens to temperature at different levels of greenhouse gas in the atmosphere. Compare levels of greenhouse gas from the 1700s, the ice age, and today. After you record that temperature data you can manipulate the level of greenhouse gas and see what happens. The yellow photos are light that are coming to the Earth from the Sun and the red are infrared photos also known as heat.


  1. In this experiment, sort of we got to see the difference in how much CO2, CH4, and N2O were in different periods of time. I noticed that as time kept going the numbers of CO2 went up highly, the levels of methane also went up but not as noticeable, and the N2O in the atmosphere went up but not as drastic. It is obvious that as time keeps goes by, if we don't change the way we are living, sooner or later we are going to be in HUGE trouble. Jasmin D.

  2. i actually like this experiment. it was interesting. i didnt know that changing the gas house concetration to it being "lots" the temperature would go higher than all the other temperatures. the temperature with up to 67.

  3. as we went through each time period, i saw how each time period had differnt levels of green house gas effects. the most was during the present day and the least was during the ice age. i also recognized how the difference in brightness there was between the periods.

  4. I enjoyed doing this simulation of the greenhouse effect because it shows the carbon dioxide methane and its max temp in the present day 1750 and ice age.


  5. The different time periods showed me the difference between the levels of green house gas effects. Present day has the most. It isn't that shocking considering the amount of c02 in the astmosphere.

  6. This blog spot showed me different green house gas concentrations and I was able to also do my own scene to test and view how it would look if not alot of CO2 was in the air.

  7. I really enjoy doing this because it helped me understand a little better about the levels of the greenhouse effects. The best part was we had the chances to do our own scene of co2 concentration.

  8. it was awesome doing this little experiment with changing the year. every time the year was change, a persom can tell that the carbon dioxide,methane, nitrous oxide, and temperature would constantly change. once, you change the greenhouse gas concentration to "lots" than you will notice that the only thing you can see would be the temperature.
