Ice in the Arctic

 From http://news.bbc.co.uk/2/hi/science/nature/7303385.stm

In February of 1985 what percentage of ice in the arctic was 6 or more years old?

In February of 2007 what percentage of ice in the arctic was 6 or more years old?

In February of 1985 what percentage of ice in the arctic was less than a year old?

In February of 2007 what percentage of ice in the arctic was less than a year old?

What do you think this change means?
