A new analysis of data from dedicated satellites 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 currently underway in Doha.
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."
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.
If the Greenland ice losses aren't accelerating, there's no real reason to worry about them.
I'm sure we'll all be seeing this covered widely on our news networks.
Maybe now that this religion is seen to be a farce, people could turn to The Truth.
Doubtful but there's always Hope.
