Blasphemy I tell ya... blasphemy!
A new analysis of data from dedicated satellites shows that one of the
main factors predicted to drive GlobalWarmingrising 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.
Aren't you?
Maybe now that this religion is seen to be a farce, people could turn to The
Truth.
Doubtful but there's always Hope. |
