Abstract

Digital elevation models of the Northern and Southern Patagonia Icefields of South America generated from the 2000 Shuttle Radar Topography Mission were compared with earlier cartography to estimate the volume change of the largest 63 glaciers. During the period 1968/1975-2000, these glaciers lost ice at a rate equivalent to a sea level rise of 0.042 +/- 0.002 millimeters per year. In the more recent years 1995-2000, average ice thinning rates have more than doubled to an equivalent sea level rise of 0.105 +/- 0.011 millimeters per year. The glaciers are thinning more quickly than can be explained by warmer air temperatures and decreased precipitation, and their contribution to sea level per unit area is larger than that of Alaska glaciers.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Recent mass balance measurements consistently show an increasing ice loss from ∼15 Gt yr−1 between ∼1940-2000 to ∼25 Gt yr−1 between ∼2000-2012.

    “Recent mass balance measurements in the Patagonian Icefields -e.g. the Shuttle-Radar Topography Mission (SRTM) or Gravity Recovery and Climate Experiment (GRACE) -often present discrepancies but consistently show an increasing ice loss from ∼ 15 Gt yr -1 between ∼ 1940-2000 to ∼ 25 Gt yr -1 between ∼ 2000-2012 (Aniya, 1996;Aniya et al., 1997;Rignot et al., 2003;Chen et al., 2007;Ivins et al., 2011”
  • GNSS, SRTM, and GRACE data, constraining the net ice mass balance only during the last few decades, still show some discrepancies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
