TUCSON, AZ (Tucson News Now) -

In mid-Setember, Arctic Sea Ice reached its lowest numbers since satellite observation records begin in the late 70s. 

The average extent of sea ice coverage from 1979 to 2000 is about the size of the Lower 48 (minus Washington and Oregon). 

Since a lot of us don't have a very clear idea of just how big the ice melt was for the Arctic this year, National Snow and Ice Data Center scientist Walt Meier mapped a comparison between the Lower 48 and the Arctic. 

Check it out in the image below. 

The map also compares this year with 2007, which was the previous record low Arctic sea ice year.
