Solid red line is the reconstructed 40 year smoothed, late-summer Arctic sea ice extent from Kinnard et al. (2011). Shaded area shows 95% confidence interval. Blue dashed line shows modern observations.

This graphic is from Skeptical Science, where you can also download a higher res version and learn more about the background for these data. Also, on that page is a link to a large number of useful graphics related to climate change.
