Interesting you cut - off total ice extents at 2012, especially since the total extent of Arctic sea ice has actually increased since then, and in fact the Antarctic ice extents are at a RECORD MAXIMUM — so things aren't always what they appear to be in a very complex system known as global climate.
As the rate of ice loss has accelerated, its contribution to global sea level rise has increased from a little more than half of the total increase from 1993 - 2008 to 75 - 80 percent of the total increase between 2003 - 2007.
Jim, you might consider whether or not total sea ice is a good indicator of the relationship between CO2 and global temperature.

Kjær, Kjeldsen and Korsgaard's team shows that the ice sheet «contributed substantially to sea level rise throughout the 20th century, providing at least 25 ± 9.4 millimeters of the total global mean rise,» writes Csatho, an associate professor of geology in UB's College of Arts and Sciences, in her News and Views analysis.
In combination with the low Arctic sea ice extent for November, this produced a remarkably low global sea ice total.
The Greenland ice sheet (GIS) has been melting so slowly and so negligibly in recent decades that the entire ice sheet's total contribution to global sea level rise was a mere 0.39 of a centimeter (0.17 to 0.61 cm) between 1993 and 2010 (Leeson et al, 2017).
All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).
The melting contributes to about 1 % of the global sea level rise — a small contribution and only 3 — 4 % of the total contribution from global glaciers and ice caps.
The total global ice mass lost from Greenland, Antarctica and Earth's glaciers and ice caps during the study period was about 4.3 trillion tons (1,000 cubic miles), adding about 0.5 inches (12 millimeters) to global sea level.

Current total ice - loss in Greenland is running at an estimated 200 Gte / yr and Antarctica at 150 Gte / yr (with ice mass gain in the east and loss in the west — with some estimates of a net gain)-- at that rate of 1mm / yr, by 2100 the global ice - loss would raise sea level by a little over 3 inches.
Arctic and global sea ice totals have moved consistently downward over 38 years.
But one modeling study put the threshold level for the eventual near - complete loss of Greenland's ice sheet at a local warming of just 2.7 C — which, due to Arctic amplification, means a global warming of only 1.2 C. Total melting of Greenland — luckily, something that would likely take centuries — would raise sea levels by 7 meters, submerging Miami and most of Manhattan, as well as large chunks of London, Shanghai, Bangkok and Mumbai.
