What amount of carbon dioxide affects a temperature change in the atmosphere?

The more carbon dioxide there is in the atmosphere the decrease of the temperature will be slower and the increase in temperature will be faster because the more carbon dioxide, particles there are the more heat the particles will hold.

1. Obtain Resources:
2. Place Thermometer in vacuum bell jar.
3. Place one cup of carbon dioxide in vacuum bell jar and seal it.
4. Let carbon dioxide sublimate.
5. Place reflector lamp a ¼ of an inch away from vacuum bell jar.
6. Turn on reflector lamp and start clock.
7. Record temperature in log book every 15 minutes.
8. When thermometer reaches 40 degrees Celsius turn off lamp.
9. Record temperature every 15 minutes until thermometer reaches 19 degrees Celsius.
10. Do experiment twice for clear results.
11. For experiment with air place thermometer in vacuum bell jar.
12. Seal the vacuum bell jar.
13. Repeat steps 5-10.
14. For experiment with 50% carbon dioxide repeat steps 2-4.
15. Hook up pump and barometer to vacuum bell jar.
16. turn pump on.
17. Turn pump off when the barometer reaches 15mm mercury.
18. Let air seep in.
19. repeat steps 5-10 .

The carbon dioxide did affect both the temperature decrease and increase. My hypothesis was wrong for the increase in temperature of carbon dioxide. The increase in temperature for carbon dioxide was slower than the increase of temperature for the air. The carbon dioxide took longer for the heat to rise which made the time of the increase of the temperature longer. My hypothesis was right for the decrease of temperature of the carbon dioxide. The carbon dioxide held more heat causing the temperature decrease to be longer.

In my experiment I wanted to prove that carbon dioxide creates global warming. During this experiment I discovered that God does whatever he pleases to the world. He will take care of the world for us, but he does not want us to sit back and not try to take care of the world. He wants us to take care of what he has given us. We know god is sovereign from Psalms 135: 6-7, The lord does whatever pleases Him in the heavens and on earth, in the seas and all there depths. He makes the clouds rise from the ends of the earth; He sends lightning with rain and brings out wind from His storehouse.
