Rapidly changing climate and global warming are exposing an unseen Arctic landscape. The land remained covered under ice sheets for about 40,000 years. New research published in Nature Communications revealed the fact about melting ice. The study indicates climate change is the driving force behind the glacial-retreat. Currently, the Arctic temperatures are rising rapidly. Researchers say Baffin Island is a rocky and frozen wonderland located in the Arctic circle between Greenland and the northern coast of Canada. It is a perfect place to study ice age patterns. Gifford Miller from the University of Colorado Boulder has been exploring the region for 40 years. The transformations uncovered by him are surprising.
The Arctic is warming two or three times faster than the entire world. Miller suspects the glacier Baffin could be no more if the melting of ice persists. According to the scientists of Colorado Boulder, the Canadian Arctic may see its warmest century in as many as 115,000 years. Simon Pendleton, study’s leading author, stated the Arctic is currently melting faster than thought. So it is sure that glaciers and ice caps could disappear in the upcoming centuries. Pendleton and team collected few plants from the edge of ice caps present on Baffin Island. They also performed various experiments as part of the research.
As per previous observations, the greenery will disappear as soon as it loses the proactive ice layer. Thus the scenario allowed scientists to make a reasonable hypothesis. Researchers assumed that vegetation collected during the research was covered with ice since its original growth period. They used radiocarbon dating to reveal the time through which the plants remained frozen. Pendleton usually says there are various plant ages in different topographical conditions. A location with higher altitude may hold ice for an extended period. But the degree of warming is so high that everything is melting everywhere. Researches forecast if the situation persists for the next few centuries, the island could be completely free of all ice.
