New paper finds climate models are unable to reproduce the known climate of the past 6,000 years

The Hockey Schtick
"A new paper published in Climate of the Past finds climate models are unable to reproduce the climate change of the past 6,000 years found by temperature proxies. According to the authors, "Independently of the choice of the climate model, we observe significant mismatches between modelled and estimated SST [Sea Surface Temperature] amplitudes in the trends for the last 6,000 years," and climate model "SST trends underestimate the [proxy] SST trends by a factor of two to five. For [a different proxy], no significant relationship between model simulations and proxy reconstructions can be detected." The paper adds to many other peer-reviewed papers finding climate models are unable to reproduce the known climate of the past, much less the future."
