Climate change has been a rising concern over the past years all over the world. More countries continue to experience unexpected weather changes, with alarming forces of nature such as torrential floods seeming like a plague every now and then.
As an ulterior response, a group of scientists are now proposing to “refreeze the Arctic”. Research has shown that the increasing sea level as a manifestation of climate change is largely contributed by the melting Canadian glaciers, according to CBC Canada.
Refreezing the Arctic
This plan involves the use wind-powered pumps to stop the Arctic glaciers from continuously melting. This possible solution is being estimated to cost up to $500 billion US. The project aims to place 10 million of these devices over ten percent of Arctic space, a “real-world” solution aside from cutting on carbon dioxide emissions, says astrophysicist Steven Desch. As the lead author of this proposal, Desch is working together with a group of students at Arizona State University.
The objective behind the wind-powered pump project proposed by Desch is due to the fact that less ice means a depleted inability to reflect excess sunlight into space. By attempting to refreeze the Arctic, this would allow heat to become unabsorbed in these regions, and prevent further depletion of the ice caps into the surrounding waters.
Canadian glaciers add to sea level rise
Data analyzed by a team of University of California researchers showed that from 1991 until 2015, melted surface ice off the Queen Elizabeth Islands has been greatly increasing since 2005. This makes it a huge factor to the rise in sea levels, as stated in a Natural Science News post. Overall, an estimated 90% in sea level rise also now comes from melting ice caps atop mountains.
The team also reflected on the worsening global warming effect that continues to deplete natural oxygen levels adding to a related increase in CO2 atmospheric levels.
