So much for " It has never been as hot as now "

Some interesting Numbers !

Atmospheric CO₂ levels may have varied by thousands of ppm throughout the MKH. Mean annual temperatures at the poles during the MKH exceeded 14 °C ...

Meanwhile, deep ocean temperatures were as much as 15 to 20 °C (27 to 36 °F) warmer than today's... one study estimated that deep ocean temperatures were between 12 and 20 °C during the MKH. The poles were so warm that ectothermic reptiles were able to inhabit them...

Between 70 and 69 Ma and 66–65 Ma, isotopic ratios indicate elevated atmospheric CO2 pressures with levels of 1000–1400 ppmV and mean annual temperatures in west Texas between 21 and 23 °C (70 and 73 °F).
