Icebergs the size of Singapore could be playing a bigger role in how much carbon the Southern Ocean absorbs than previously thought, a new study says. The findings suggest that if more icebergs break off from Antarctica's ice sheets in a warmer world, they could inadvertently boost ocean carbon storage. This could help to offset the accumulating CO2 in the atmosphere by a few percent, the researchers say. [Source: CarbonBrief]
