The glacial lakes of northern Quebec–Labrador and their contribution to the meltwater discharges of the late deglaciation and early Holocene climate interval

The climate variability of the last 15,000 to 7,000 years is commonly linked to the drainage of large glacial lakes that had developed at the margins of the decaying ice masses of the last Ice Age. These massive outbursts of meltwater are believed to have disturbed the North Atlantic Ocean circulation, which plays a fundamental role in regulating Earth’s climate. These former climate-forcing events are now under focus due to a growing number of studies showing that the present-day increase in freshwater releases from the melting of Greenland and other Arctic glaciers may potentially lead to a slowdown of the ocean thermohaline circulation and cause important climate feedbacks.
