Extended Data Figure 2

a, Decadal trends of the corrected reconstruction (1982–2008). Stippled trends are statistically significant (at a 90% confidence level or higher using Student’s t-test). b, Mean of the reconstruction (1982–2008). c, Mean of the corrected reconstruction (1982–2008). d, Mean of the non-gridded ICESat-1 data (2003–2008, 13 campaigns). e, Reconstruction minus non-gridded ICESat-1 data (2003–2008). f, Corrected reconstruction minus non-gridded ICESat-1 data (2003–2008). g, Mean of the ASPeCt data (1980–2005). h, Reconstruction minus ASPeCt data (1980–2005). i, Corrected reconstructions minus ASPeCt data (1980–2005). The thick grey line marks the mean sea-ice edge (1% sea-ice concentration). Differences are based on data points when both respective products were available. Data points without data in the sea-ice-covered region are shaded in grey in di. See Methods for details.
