class=\"wp-block-paragraph\">It is important to remember that both the&nbsp;<a href=\"https:\/\/gracefo.jpl.nasa.gov\/data\/grace-fo-data\/\">NASA\u2019s GRACE Ice Mass team<\/a>&nbsp;and Zwally et al. use the same data sets to determine their estimates of losses and gains.&nbsp;&nbsp; The differing results are then an indication of the different approaches to interpretation of that data, which may include biases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">NASA\u2019s climate.gov doesn\u2019t quite agree with Zwally et al. yet.&nbsp; But the Vital Signs graphic is for \u201cAntarctic Ice Mass in Gts\u201d&nbsp; . . . and that total ice mass has been level since turn of the century, with a lot of variation.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compare Zwally\u2019s&nbsp; 2021 estimate of -12 GT a year with the GRACE figure of -137 GT a year (in the two panel image,&nbsp; on the right).&nbsp; Zwally\u2019s runs through the end of 2016.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Don\u2019t think for a moment that Jay Zwally is some kook on the shady fringes of NASA \u2013&nbsp;<a href=\"https:\/\/www.thetippingpoints.com\/scientists\/dr-jay-zwally\/\" target=\"_blank\" rel=\"noreferrer noopener\">he is one of their top flight scientists and led the 2003 ICESat

talks<\/a>&nbsp;in 2019.&nbsp;&nbsp; And he has firmly stated that his Antarctic Ice Mass work is not a repudiation of climate science\u2014it is just solid evidence that Antarctic Ice Mass is not plummeting as the Climate Crisis Team claims. &nbsp;(One might rightly ask why, then, don\u2019t the creators of the Vital Signs Ice Sheets page present his results alongside of those of the GRACE team.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>So what\u2019s the news?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The news is that some clever scientists \u2014 Collin M. Schohn, Neal R. Iverson, Lucas K. Zoe , Jacob R. Fowler, and Natasha Morgan-Witts \u2014 had decided that instead of blindly following the long-standing formulas for glacier ice flow, maybe they ought to find out, using real experiments, if those formulas actually reflect what happens in the physical universe where glaciers, ice under pressure, are flowing and melting.&nbsp; It took them ten years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The story is covered in this&nbsp;<a href=\"https:\/\/scitechdaily.com\/\" target=\"_blank\" rel=\"noreferrer noopener\"><em>SciTechDaily<\/em><\/a><em>&nbsp;<\/em>article:&nbsp;&nbsp;<a href=\"https:\/\/scitechdaily.com\/glacier-experts-uncover-critical-flaw-in-sea-level-rise-predictions\/\" target=\"_blank\" rel=\"noreferrer noopener\"><em>Glacier Experts Uncover Critical Flaw in Sea-Level Rise Predictions<\/em><\/a><em>.&nbsp;<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Disclosure:&nbsp; I am not a glaciologist.
