Cooler water in South Pacific could mean winter chill for Fairbanks
The long-range weather seers say there is a 44 percent chance that the mean temperature will be colder than 7.9 below from December through February.
WEBCommentary(tm) - Greenland Temperatures of the Past Millennium
The figure below depicts the central Greenland surface temperature reconstruction produced by the six scientists; and as best as can be determined from this representation, the peak temperature of the latter part of the Medieval Warm Period—which actually began some time prior to the start of their record, as demonstrated by the work of Dansgaard et al. (1975), Jennings and Weiner (1996), Johnsen et al. (2001) and Vinther et al. (2010)—was approximately 0.33C greater than the peak temperature of the Current Warm Period, and about 1.67C greater than the temperature of the last decades of the 20th century. In addition, it is worthy to note that between about 1400 and 1460 there was also a period of notable warmth in Kobashi et al.’s temperature reconstruction, which aligns well with the “Little” Medieval Warm Period, the peak temperature of which was about 0.9C greater than the temperature of the last decades of the 20th century and the first decade of the 21st century.
