claim: "...there has been no increase in the global average surface temperature for the past 16 years" (Judith Curry and David Rose)
evidence: In the Paleocene, with a global average temperature of about 24–25 °C (75–77 °F), compared to 14 °C (57 °F) in more recent times, the Earth had a greenhouse climate without permanent ice sheets at the poles, like the preceding Mesozoic.
