How to Use

Greenhouse Effect tab:
Tools: 

-Legend: sunlight photon is yellow and comes down from the sun

         infrared photon is red and comes up from the earth





-Greenhouse Gas Concentration:
ranges from none to lots. this changes the amount of infrared photons emitted from the earth.

-Atmosphere during...      

           Today: CO2 is 388ppm 

           1750: CO2 is 280ppm

           Ice age: CO2 is 180ppm.
Notice the change in Greenhouse Gas Composition

-Options 

           change the number of clouds. increasing the number of clouds will lead to an increase of                        temperature 

           -change unit of temperature from Fahrenheit/Celsius to Celsius/Kelvin
          - view all photons: selecting this will display all the photons              from the entire simulation time. 

                                                                                                        


When you start The Greenhouse Effect  the earth temperature is reset to cold and light photons start coming from the sun and  Infrared photons emerge from the earth.
You can use different tools to change the photon and temperature changes.
               - speed slider , pause/play , and step-by step
Selecting view all photons increases the  number displayed.
Use the slider to explore different concentrations.
The model does not explicitly include specific greenhouse gases.
The temperature is measured close to the earth’s surface. The model matched average surface temperatures from the given time periods.

After exploring the available tools, begin interacting with the simulation.
