New research suggested Arctic ice melt is diluting ocean CO2 clean-up role

After the news that the 2014 Arctic ice minimum was the sixth lowest since 1978 (http://www.theweatherclub.org.uk/news/article/2014-arctic-sea-ice-minimum-sixth-lowest-on-record), new evidence suggests that as Increasingly larger areas of Arctic sea ice melts into the ocean it is reducing its vital function of removing CO2 from the atmosphere.

Warming in the Arctic is already linked to a number of climate feedbacks: changing climate patterns in temperate zones and reducing the planet’s albedo and thus its ability to reflect sunlight. This new research is one more to add to the collection.

Scientists at the Greenland Institute of Natural Resources and the University of Southern Denmark have discovered that in addition to ocean water, sea ice itself helps removes carbon dioxide from the atmosphere.

“We...thought that this did not apply to ocean areas covered by ice, because the ice was considered impenetrable,” Søgaard said. “However, new research shows that sea ice in the Arctic draws large amounts of CO2 from the atmosphere into the ocean.”
