Melting glaciers reveal Canadian land hidden for 40,000 years

Melting ice is exposing hidden landscapes in the Canadian Arctic that haven’t been seen in more than 40,000 years, new research published in Nature Communications reveals.

Unsurprisingly, the study suggests climate change is the driving force behind this record-breaking glacial retreat and with Arctic temps rising at increasing speed thanks to strong positive feedback loops in the polar regions, we can expect things to heat up even quicker in the near future. According to researchers at the University of Colorado at Boulder, the Canadian Arctic may be seeing its warmest century in as many as 115,000 years…

❝ Simon Pendleton and colleagues’ research is based on plants collected at the edge of ice caps on Baffin Island, the fifth-largest island in the world. The landscape is dominated by deeply incised fjords and high-elevation, low-relief plateaus. The latter conserves lichens and moss in their original position in the ice for periods of time lasting thousands of years — a little like a cryogenic chamber.

RTFA to learn why scientists like Pendleton have to be hot on the spot to gather samples of vegetation as it becomes exposed.
