These scientists have found that, in the
absence of any significant CO2 concentration changes or human influence during the Holocene (i.e., the last ~ 10,000
years), the deep oceans naturally warmed by more than 2 °C in a span of just 200
years, which is several times the rate in which they are alleged to have warmed in the last ~ 60
years of the
supposedly dominant anthropogenic influence on climate.
