From Watts Up With That?

Guest Post by Willis Eschenbach

Those who read my work may recall my post called “Munging the Sea Level Data“. In it, I showed that the apparent acceleration in the satellite sea level was merely an artifact of the combining of the four satellite records, viz:

Despite the obvious differences between the first and last halves of the record, scientists merely spliced them together and obscured the splice. My conclusion in that post was:

There’s no evidence of any acceleration in the rate of sea-level rise in either the tide gauge or the shabbily-spliced satellite records.

So today I stumbled across a paper published in Nature magazine entitled A revised acceleration rate from the altimetry-derived global mean sea level record. Care to guess what the paper says?

Yep. You’re right. They conclude that once they took a hard look at the satellite records, the problem was disagreement between the satellites … and once they applied their correction methods to the TOPEX satellite records, they found:

Based on four different weighting methods used in a tide-gauge comparison it is determined that TOPEX is drifting and not ERS. Therefore, we suggest to calibrate the TOPEX GMSL record with the crossover of ERS1&2 after the removal of cal-1. The calibration reduces the observed acceleration in GMSL, so that it becomes statistically equivalent to zero at the 95%-confidence level.

The observed acceleration in satellite-observed GMSL (global mean sea level) is “statistically equivalent to zero” … go figure.

Here where I live on the northern California coast, we’re getting the blessing of an “atmospheric river”, which is a phenomenon where lots of moisture comes from the tropics up to the west coast in a narrow band. It used to be called the “Pineapple Express”, but I suppose that was determined to be racist against pineapples or something …

Given the several years of the recent drought, this is more than welcome. We got 3-1/2 inches (9 cm) of rain yesterday, with more expected tonight.

So, wet blessings to all.
