as the paper is open to public comments, I've submitted one: http://www.atmos-chem-phys-discuss.net/15/20059/2015/acpd-15-20059-2015-discussion.html Points made: —
No statistically significant acceleration of sea level rise since 1700
Watson finds
no statistically significant acceleration in the long time series European tide gauges.
That rebuts your statement that: «There is
no statistically significant acceleration in sea level rise that can be attributed to human caused warming»
Re: «There is
no statistically significant acceleration in sea level rise that can be attributed to human caused warming»
«There is
no statistically significant acceleration in sea level rise that can be attributed to human caused warming» But there is acceleration.
They also note that «There is considerable variability in the rate of rise during the twentieth century but there has been
a statistically significant acceleration since 1880 and 1900 of 0.009 ± 0.003 mm / year2 and 0.009 ± 0.004 mm / year2, respectively.»
Not exact matches
Why do they repeatedly drone on about «deceleration» when the average of the
acceleration rates they measure, even for their extremely limited and restricted sample, isn't
statistically significant?
Mind you I would say, even though I haven't done any tests, that his claim of an
acceleration in the rate of warming is almost certainly not
statistically significant.
«Sure, they'll probably try to confuse us with trick questions: Like why, apart from natural 1998 and 2015 El Nino spikes, satellites haven't recorded any
statistically significant global warming for nearly two decades; why sea levels have been rising at a constant rate of 7 inches per century without
acceleration; and why no category 3 - 5 hurricanes have struck the U.S. coast since October 2005 — a record lull since 1900.
Statistically significant upward velocity and
accelerations are recorded at 27 GPS stations, predominantly located in the Central Highlands region of Iceland, where present - day thinning of the Iceland ice caps results in velocities of more than 30 mm / yr and uplift
accelerations of 1 — 2 mm / yr2.
Although the global temperature data show short periods of greater and smaller warming trends, and even short periods of cooling, the team's key question was whether or not these are
statistically significant in showing a change in the form of a slowdown or
acceleration of global warming, or whether they are merely expected fluctuations — or noise — in the data.
