One solution to the melting ice cap: Refreeze it. It wouldn’t even cost that much
A record loss of Arctic sea ice and faster-than-expected melting of Greenland’s ice cap made worldwide headlines in 2012, but research published in major science journals in the fall suggest warming in the North doesn’t have to continue.
We could refreeze the Arctic, proposed a paper in Nature Climate Change. It wouldn’t even cost that much, said an affiliated study in Environmental Research Letters. The question is should we? (AP Photo/Ian Joughin; NASA)
