The “science” is inconclusive since you a record of 500
years to prove or disprove human caused climate change.
Tree rings show that there was a long period of draught
and heat long before human appearance on earth.

I prefer the ice core records. The problem with tree rings is their growth is sensitive to other things besides temperature such as rainfall and (gasp) CO2 concentration.
