Tide gauge data for the UK has just been published by PSMSL for 2017, so we can take a look at the latest numbers for the two major, long running sites at North Shields and Newlyn:

Long term rates of rise are similar to what we are used to seeing globally, although it must be pointed out that the coast at Newlyn is sinking, maybe by as much as 1mm/year. (See above map).

 

The 120-month running totals show the enormous amount of variability, not just on a monthly or annual basis, but even over much longer periods.

Little wonder then that proper oceanographers advise against relying on such short term trends. For instance, Bruce Douglas stated in 1996:

It is well established that sea level trends obtained from tide gauge records shorter than about 50-60 years are corrupted by interdecadal sea level variation

NOAA publish 50-year sea level trends for major sites. These are run at 5-year intervals, and have recently been updated for 2015.

Data for North Shields and Newlyn shows the same cyclical pattern that we see globally – sea levels were rising just as fast as now during most of the 20thC up to around 1970, before a slowdown in the 1970s and 80s.

Indeed, sea level rise at North Shields was much higher than now for much of the 20thC:

There is no evidence at all at either North Shields or Newlyn that current sea level rise is in any way unprecedented.

    What a relief that our sea level rise will be minimal!

    Perhaps we could prepare to accept an influx of climate refugees from our cousins across the pond. Only 2 days ago the Graun predicted impending devastation ….

    Thank you for this.
    Details like this are needed to argue against those ‘global’ maps that link tide gauge and satellite altimetry to claim a recent acceleration. Cannot have it globally if it is not there locally.

      Indeed, Geoff. As with so much else in the world outside Catastropolis, nothing to see here; move along.

    Reblogged this on WeatherAction News and commented:
    But, but, but Paul…the Times said its doom;

    Dublin and Cork will face energy blackouts by 2050 as power plants are flooded by rising sea levels, a study has warned.

    Belfast would also face a direct threat of flooding caused by climate change if radical changes are not made worldwide to tackle rising temperatures.

    Irish people will be among billions of city dwellers likely to be threatened just 30 years from now, say researchers. Coastal cities will be hit by heatwaves, flooding, food and water shortages.

    https://www.thetimes.co.uk/article/rising-sea-levels-will-hit-power-stations-in-next-30-years-865lvz7lc#

    Who are these sage ‘researchers’ foretelling the doom 500mm rise in 30 years (i. e. ~17mm per year)? ;

    The study was carried out by environmental lobby groups and C40 Cities, a group of cities taking action on climate change.

    Oh!

    And who funds C40?

    Clinton Foundation
    World Bank
    ….
    UK Government!!!

    So we help fund this nonsense. 🤐

    I thought the Greens wanted the sealevel to rise so they can have more tidal power!

    Are the climate data torturers running out of ideas?

    In a document for the Shoreham £30+M flood defence:-

    “In line with the Strategy recommendations and FCRM-AG, an adaptive approach to
    climate change has been adopted within the design of the Improve options, with 50
    years of sea level rise incorporated within the design (320mm). ”

    They (environment agency) seem to be using 6.4mm/yr in order to cost/benefit/justify this waste!

    Newlyn is the origin benchmark for all of the UK’s geodetic levelling, so there is a lot known about it and very careful observations for over 100 years. More recently, GPS observations show that Newlyn is sinking at 0.7+/-0.2 mm per year. This needs to be subtracted from the linear trend of 1.8mm per year, to give an actual sea level rise of 1.1mm/yr. Frightening stuff!
