The red outline in the picture to the left shows how large the Polar Ice Cap was in 1979. The white are in the picture is how big the Polar Ice Cap currently is‚ that’s a significant decrease over just thirty five years. The thinner the ice gets the faster it melts. Besides the shrinking‚ the arctic sea ice is also forming later and later every year. This is directly impacting
