Last Interglacial Warmth on Canada's Baffin Island: Part 2
Francis, D.R., Wolfe, A.P., Walker, I.R. and Miller, G.H. 2006. Interglacial and Holocene temperature reconstructions based on midge remains in sediments of two lakes from Baffin Island, Nunavut, Arctic Canada. Palaeogeography, Palaeoclimatology, Palaeoecology 236: 107-124.

What was done
In a companion study to that of Frechette et al. (2006), Francis et al. analyzed midge (principally chironomid) remains found in cores recovered from two of the same Baffin Island lakes (Fog Lake and Brother of Fog Lake) for which Frechette et al. analyzed pollen spectra, reconstructing lake water temperatures and mean July air temperatures for both the Holocene and the prior interglacial period.

What was learned
The midge study of Francis et al. revealed, in their words, that "peak Holocene temperatures occurred in the first half of the period, and have decreased since about the mid-Holocene." As in the pollen study, however, warmer still was the prior interglacial, when they say that "reconstructions at both [lake] sites indicate that summer temperatures during the last interglacial were higher than at any time in the Holocene, and 5 to 10C higher than present [our italics]."

What it means
Ever more evidence continues to indicate that earth's current warming trend began from the coldest point of the last two interglacials, i.e., from the base level of the global chill of the Little Ice Age. Hence, it should be clear to most rational people that the planet's current warmth - even in the Arctic - is not in any way, shape or form either unusual, unnatural or unprecedented, as climate alarmists are always making it out to be. In fact, earth's current temperature is still far below the peak temperatures of both the current and penultimate interglacials, as well as the peak temperatures of the two interglacials that preceded them. Given this perspective, it is truly amazing that with so much more CO2 currently in the air (40-50% more), it is currently so much colder than it was during the peak warmth of the current and prior three interglacials.
