Title: Sea Level Rise (SLR) Acceleration satellite

Quote:
We challenge these solutions by means of a crossover analysis between TOPEX an ERS-1&2 and we derive a revised acceleration rate, whose point estimate is much reduced in magnitude with respect to those previous studies. The crossover analysis shows that not applying cal-1 is justified and removes the U-shaped drift in TOPEX-A. However, the removal of cal-1 from the whole TOPEX record leads to an intramission bias with an amplitude that depends on the applied SSB correction. Additionally, this approach reveals the presence of a drift of −1.1 ± 0.3 mm yr−1 between the TOPEX sea surface heights and those of ERS-1&2. An alternative approach consists in removing cal-1 from TOPEX-A alone, which yields a negligible intramission bias in case the Gaspar et al.12 SSB correction is applied. Also in this case, a drift between TOPEX and ERS of −1.3 ± 0.1 mm yr−1 is found, with is statistically equivalent to the previous value.

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.

So no SLR acceleration from the satellite record then. Good to know. ;)

The thermal expansion of water from increased average global temperatures would be countered by more ocean water evaporating and being condensated as rainfall over land areas (that absorb the water for some time). Some article from the early 2010s stated that the average ocean heights dropped by a mere 10mm because of the absorption of heavy rainfall over desert Australian regions.

So those Pacific and Torres Strait Islands are faking it. Can't trust the bastards.

You mean those islands that have actually increased in size?

"Hundreds of Pacific Islands are getting bigger despite global warming"
