The 'ancient ice' is virtually gone,except at very high latitude.The annual ice which does form is not long-lived.
The snow which used to cover the ice,and reflected 85% of sunlight, cannot tolerate the new warmer temperatures.
The exposed ice only reflects as little as 70% of the light.
Once this thin ice melts,the open water only reflects 6.5% of the light.
With the ice gone,for every pound of ice lost,each pound of water can gain 144-degrees,instead of just converting from 32-F ice,to 32-F water.
This is where the runaway warming sets in,and methane clathrates melt and out-gas,beginning a double feedback amplification.
We ought to be happy that it will take as long as 2030 before we see a blue ocean event.
There's an expedition which is going to park a ship,tethered to the pack ice near the North Pole,for 352-days,and observe,first-order,winter ice dynamics.
