Summary:
- A correlation is the mutual relationship between two or more things.
- We see a correlation between three things: CO2 emissions from fossil fuel burning, atmospheric CO2 levels, and average global temperatures.
- If one factor rises while another sinks they have negative correlation.
- Causation refers to the factor that is producing the effect.
- To establish causation we need to know how one would cause the other.
- We found one cause for rising global temperatures, but there are also others.
- Outline the logical steps that link fossil fuel emissions to rising average global temperature.
