During June, I explained on WUWT that the University of Texas GRACE interpretations were wrong due to glacial rebound (isostasy.) Later in the summer they acknowledged that my explanation was correct.
a new study published in the September issue of Nature Geoscience suggests that the true melt rate might be much slower than that. (Access a PDF of the study here.) A joint team of American and Dutch scientists took another look at the GRACE data and found that Greenland and West Antarctica may be melting just half as fast the earlier studies estimated. As researcher Bert Vermeersen, a professor at Delft University of Technology in the Netherlands, told the AFP, the earlier estimates failed to account for glacial isostatic adjustment—the rebounding of the Earth’s crust after the end of the last Ice Age:
Hansen’s “non-linear” theory was ridiculous to begin with, and was undermined by the JPL study.
Under BAU [business as usual] forcing in the 21st century, the sea level rise surely will be dominated by a third term: (3) ice sheet disintegration. This third term was small until the past few years, but it is has at least doubled in the past decade and is now close to 1 mm/year, based on the gravity satellite measurements discussed above. As a quantitative example, let us say that the ice sheet contribution is 1 cm for the decade 2005–15 and that it doubles each decade until the West Antarctic ice sheet is largely depleted. That time constant yields a sea level rise of the order of 5 m this century.
His doubling has been halved. That means ice loss rates have not changed, which was obvious from sea level data. Temperatures in Antarctica are cold and getting colder.
How does this crap get through peer review? Ice doesn’t melt in summer temperatures of -10C, and Antarctica is getting colder.
