It's not often that disappearing Arctic ice is presented as good news for the planet. Yet new research suggests that as the northern polar cap melts, it could lift the lid off a new carbon sink capable of soaking up carbon dioxide.Hooray! Except:
The findings, from two separate research groups, raise the possibility - albeit a remote one - of weakening the greenhouse effect. The researchers say the process of carbon sequestration is already underway.
Even so, the new carbon sink is unlikely to make a significant dent in the huge amounts of CO2 pumped into the atmosphere by industrial activities.Not to mention: it's the sort of thing that only works once.
