Wrong. Or should I call it a lie?
Equilibrium climate sensitivity. Paleoclimate data provide evidence to estimate equilibrium climate sensitivity (ECS15) (Section
TS.3.2.1). In AR6, refinements in paleo data for paleoclimate reference periods indicate that ECS is very likely greater than 1.5°C and
likely less than 4.5°C, which is largely consistent with other lines of evidence and helps narrow the uncertainty range of the overall
assessment of ECS. Some of the CMIP6 climate models that have either high (>5°C) or low (<2°C) ECS also simulate past global
surface temperature changes outside the range of proxy-based reconstructions for the coldest and warmest reference periods. Since
AR5, independent lines of evidence, including proxy records from past warm periods and glacial–interglacial cycles, indicate that
sensitivity to forcing increases as temperature increases (Section TS.3.2.2). {7.4.3.2, 7.5.3, 7.5.6, Table 7.11}
