Data analysis

There are the observations and inference we made from analysing the data:

1.	The temperature of CO₂ increase faster than air
2.	CO₂ absorbs heat faster than air
3.	CO₂ absorbs more heat than air
4.	Temperature of CO₂ remains higher than that of air when there is added heat
5.	CO₂ loses heat more slowly than air (1 to 2^oC). As its temperature nears the air temperature, for quite a long time is 0.1 to 0.2^oC higher

The first inference which we can make is that with more CO₂ in the atmosphere. Earth's temperature will become higher. The second inference is that with more CO₂ in the atmosphere, more heat will be retained. Both will raise the Earth's temperature.
