Hey remember all that science that said we’re all doomed in the next twenty or thirty years because of global warming and the sea rising and the glaciers melting. Well, not so much.
New science seems to be upsetting calculations on sea levels rising and climate change.
The UK Register is reporting on science coming out of Princeton that shows that “one of the main factors predicted to drive rising sea levels in future has been seriously overestimated, with major implications for climate talks.”
Recent technological advancement means that they can filter out “noise” from previously collected data.
The new methods involve filtering out noise from the data produced by the Gravity Recovery And Climate Experiment (GRACE) spacecraft, sent into orbit with the aim of finding out just how much ice is melting from the world’s ice sheets and glaciers. Such water then runs off into the sea, providing one of the main potential drivers of sea level rise – which is itself perhaps the main reason to worry about climate change.
“GRACE data contain a lot of signals and a lot of noise. Our technique learns enough about the noise to effectively recover the signal, and at much finer spatial scales than was possible before,” explains professor Frederik Simons of Princeton uni. “We can ‘see through’ the noise and recover the ‘true’ geophysical information contained in these data. We can now revisit GRACE data related to areas such as river basins and irrigation and soil moisture, not just ice sheets.”
Simons and his colleague Christopher Harig tried their new methods out on GRACE data covering the Greenland ice sheet, which is of particular interest as the rest of the Arctic ice cap floats on the sea and so cannot contribute directly to sea level rise by melting. Meanwhile the Antarctic ice cap is actually getting bigger, so Greenland is probably the major worry.
According to a Princeton statement highlighting the new research:
While overall ice loss on Greenland consistently increased between 2003 and 2010, Harig and Simons found that it was in fact very patchy from region to region.
In addition, the enhanced detail of where and how much ice melted allowed the researchers to estimate that the annual acceleration in ice loss is much lower than previous research has suggested, roughly increasing by 8 billion tons every year. Previous estimates were as high as 30 billion tons more per year.
The rate of loss of ice from Greenland is estimated at 199.72 plus-or-minus 6.28 gigatonnes per year. So the possible acceleration of losses is only barely larger than the margin of error in the readings: it’s very difficult to tell the supposed loss curve from a straight line.
In other words the possible acceleration in ice losses is barely perceptible: it may not really be happening at all. Similar results were seen not long ago in GRACE data for central Asian mountain glaciers, another suggested source for sea-level rises.
But even if it is happening, Princeton is saying that at this rate it would take about 13,000 years for the Greenland ice sheet to melt and make sea levels rise and wipe us all out.
That’s a little different from what we’ve been hearing from climatologists, huh?
The only reason I bring this up is that I know it won’t be reported in the mainstream media at all. Thus it seems once again that the global outbreak of Gaia worship doesn’t really stand on science but on faith. How much you want to bet that they’ll reject these technological advancements that shows folks like Al Gore to be hucksters and only use the old data (which by the way was also proved to be untrue.)
Next thing you know, they’ll be treating scientists like…Galileo.
