ack to Mann, he used proxies (mostly tree rings) to estimate temperatures back deep into the past. He assumed that temperature is the primary factor that affected tree growth in the past, not rainfall, not local effects of tree crowding, shadowing, etc.

Nope, incorrect.

Rainfall is the primary factor in tree rings width for most species.

And Mann knew that.

That fact has been around for over 100 years.
