Between the 10th and 14th centuries AD, earth's average global temperature may have been warmer than it is today, according to the analyses of Lamb (1977, 1984, 1988) and Grove (1988). The existence of this Medieval Warm Period was initially deduced from historical weather records and proxy climate data from England and Northern Europe. Interestingly, the warmer conditions associated with this interval of time are also known to have had a largely beneficial impact on earth's plant and animal life. In fact, the environmental conditions of this time period have been determined to have been so favorable that it was often referred to as the Little Climatic Optimum (Imbrie and Imbrie, 1979; Dean, 1994; Petersen, 1994; Serre-Bachet, 1994; Villalba, 1994)
At the end of the day, then, it would indeed appear that the peak warmth of the global Medieval Warm Period clearly exceeded that of the global Current Warm Period.

Does this account for Super El Nino around the turn of the last century?ReplyDelete
Does warming increase El Nino frequency/intensity?Delete
A highly controversial topic, many paleoclimate papers show the opposite
Actually my question pertained to the peak temperature of this Modern Warm Period that we reached with the Super El Nino in 1998 (these studies seem focused around the late 1980s-early 1990s). If you include that, then we actually just about matched the peak warmth of the Medieval Warm Period, if not surpassed it.Delete
