Another Hit for Sea Level Rise Alarmism — Antarctic Ice Shelves Not Melting

Antarctic ice shelves not melting at all, new field data show — Crafty boffins got elephant seals to survey for them
Details at the UK Register:
Twenty-year-old models which have suggested serious ice loss in the eastern Antarctic have been compared with reality for the first time – and found to be wrong, so much so that it now appears that no ice is being lost at all.
“Previous ocean models … have predicted temperatures and melt rates that are too high, suggesting a significant mass loss in this region that is actually not taking place,” says Tore Hattermann of the Norwegian Polar Institute, member of a team which has obtained two years’ worth of direct measurements below the massive Fimbul Ice Shelf in eastern Antarctica – the first ever to be taken.
According to a statement from the American Geophysical Union, announcing the new research:
It turns out that past studies, which were based on computer models without any direct data for comparison or guidance, overestimate the water temperatures and extent of melting beneath the Fimbul Ice Shelf. This has led to the misconception, Hattermann said, that the ice shelf is losing mass at a faster rate than it is gaining mass, leading to an overall loss of mass.
You can read the rest of the article HERE, but this is the conclusion (my emphasis added)
Overall, according to the team, their field data shows “steady state mass balance” on the eastern Antarctic coasts – ie, that no ice is being lost from the massive shelves there. The research is published in the journal Geophysical Research Letters.
This is good news indeed, as some had thought that huge amounts of ice were melting from the region, which might mean accelerated rates of sea level rise in future.
The National Academy of Scientist study of sea level rise is based on computer models and here is proof that the computer models are in error. Now will the NAS study be with drawn or revised. Not likely, as sea level alarmism is more about politics rather than scientific truth.
