>I mean of course a single proxy, so not a graph of various measurements pasted together. for instance, tree rings only.
OK, but why? Why would you not look at all the data?

>thermometer data is extremely sparse from 1880
Wrong. See >>15206822

>so proxy data is where we guestimate global temperature, which is why I'd like a single proxy dataset.
Your mistaken impression of the thermometer record explains why you want a temperature reconstruction from proxy data, it doesn't explain why you only want one source of proxy data.

>why is irradiance the only important energy output?
There is solar wind, which doesn't have an effect on our climate, and indirect magnetic effects which have a weak effect on cloud formation. Nothing significant compared to irradiance.
