What was done
The authors summarize the main characteristics of the glacial and climatic history of the Canadian Arctic's Baffin Island since the Last Glacial Maximum by presenting biotic and physical climate proxy data derived from six lacustrine sediment cores recovered from four new sites on Baffin Island, after which the paleoenvironmental implications of the new data are combined with findings of prior studies to develop a regional picture of climatic conditions during deglaciation, the subsequent Holocene thermal maximum, the onset of Neogolaciation and its intensification in the late Holocene.

What was learned
Miller et al. report that "glaciers throughout the Canadian Arctic show clear evidence of Little Ice Age expansion, persisting until the late 1800s, followed by variable recession over the past century," noting that wherever the Little Ice Age advance can be compared to earlier advances, "the Little Ice Age is the most extensive Late Holocene advance," and that "some glaciers remain at their Little Ice Age maximum."

What it means
Since the Little Ice Age in the Canadian Arctic spawned the region's most extensive glacial advances of the past several thousand years, and since many of the resulting glaciers persisted into the late 1800s, with some still remaining at their maximum Little Ice Age extensions, it is only to be expected that the region should be experiencing a significant warming as the planet recovers from the global chill of this most recent cold phase of the millennial-scale oscillation of climate that reverberates through glacial and interglacial periods alike.  Being either blind to or ignoring these facts, climate alarmists wrongly associate the current warming of the Arctic with anthropogenic CO2 emissions, when in reality nothing but natural processes are at work in the region's rejuvenation.
