From the BBC, by way of Greenpeace, I stumbled across this scary graphic:

Just looking at the graph, that’s about a 50% growth in the proportion of young ice versus older ice. The graphic doesn’t portray absolute figures, just percentages. But since we know the ice cover is shrinking overall this means that older ice is disappearing faster than young ice or that young ice is “replacing” old ice, or something like that. Whichever way the actual values point, it’s a bad sign.
