"Everything is Melting Everywhere" – Arctic Warming Exponentially Faster Than Rest of Planet

Posted on Jan 25, 2019

 Baffin Island Glaciers

"The Arctic is currently warming two to three times faster than the rest of the globe, so naturally, glaciers and ice caps are "Going to react faster," said Simon Pendleton, a doctoral researcher at the University of Colorado's Boulder's Institute of Arctic and Alpine Research (INSTAAR).

"Unlike biology, which has spent three billion years developing Gifford Miller, senior author of the research and a professor of geological sciences at CU Boulder. "They're well behaved, responding directly to summer temperature. If summers are warm, they immediately recede; if summers are cool, they advance. This makes them one of the most reliable proxies for changes in summer temperature. "

Glacial retreat in the Canadian Arctic has uncovered landscapes that have not been ice-free for more than 40,000 years and the region may experience its warmest century in 115,000 years, new University of Colorado Boulder research finds. Ice caps on Baffin Island, west of Greenland.

"Uncharted Territory" -New Species Evolve During Epic Climate Change

Baffin is the world's fifth largest island, dominated by deeply incised fjords separated by high-elevation, low-relief plateaus. The thin, cold plateau ice acts as a kind of natural cold storage, preserving ancient moss and lichens in their original growth position for millennia.

"The island has experienced significant summertime warming in recent decades." "Lead author Pendleton said.

In August, the researchers collected 48 "plant samples from 30 Baffin ice caps, encompassing a range of elevations and exposures.

At the Institute of Arctic and Alpine Research (INSTAAR) at CU Boulder and the University of California Irvine, the researchers found that these ancient Plants at all 30 years ago, the past 40,000 years.

Baffin and Greenland ice cores reconstituted the warmest century for the region in 115,000 years and that Baffin could be completely ice-free within the next few centuries.

"You'd normally expect to see different plantain in different topographical conditions," Pendleton said. "A high elevation location might hold onto its ice longer, for example.
