There do exist people (even on the internet) who ask similar questions about climate change, who prefer to attribute it to all kind of other causes, and deviate or deny that human activities create climate change. I do know that wasn't part of the question, so I can only guess and hope.
The only reason "values corrected for anomalies that are not an effect of human involvement" would be interesting is to find out whether the effect of human involvement is significant or not. It is a valid question, but we already know the answer, so asking OP to essentially re-do a huge amount of climate science comes off as disingenuous.
