  • “Continued Sea Ice Decline in 2005” This graph shows the five-day mean sea ice extent for July through September for the years 2002 through 2005. All four years were below the average sea ice extent for 1979-2000 (gray line). In fact, recent sea ice extent falls below the 1979-2000 average by an area twice the size of Texas.
