Does the pope not realize how long it has been since the Earth has warmed? Almost. 2 decades. And, that the Earth was much warmer in the Middle Ages?
For those not familiar with the above poster--a troll--s/he has previously been informed on multiple occasions that (globally) the years 2005, 2010, and 2010 are now known to have been warmer than that fabled outlier year of 1998. Most of the genuine deniers have now acknowledged the increase and say things like "barely warmed since 1998" or "almost flat since 1998." This is how you know they're serious and not poes.
I believe s/he has also been told that it is NOT agreed that Earth--the entire planet--was "much warmer" in the Middle Ages. In fact (per
https://en.wikipedia.org/wiki/Medieval_Warm_Period):
"Despite substantial uncertainties, especially for the period prior to 1600 for which data are scarce, the warmest period of the last 2,000 years prior to the 20th century very likely occurred between 950 and 1100, but temperatures were probably between 0.1 °C and 0.2 °C below the 1961 to 1990 mean and significantly below the level shown by instrumental data after 1980. Proxy records from different regions show peak warmth at different times during the Medieval Warm Period, indicating the heterogeneous nature of climate at the time. Temperatures in some regions matched or exceeded recent temperatures in these regions, but globally the Medieval Warm Period was cooler than recent global temperatures.
". . . Global temperature records taken from ice cores, tree rings, and lake deposits, have shown that, taken globally, the Earth may have been slightly cooler (by 0.03 degrees Celsius) during the 'Medieval Warm Period' than in the early and mid-20th century"--and of course has warmed substantially since then.
