‘Acceleration’ In Sea Levels Found To Be False – Artifact Of Switching Satellites

sea level rise liberty nyOne of the most common arguments climate alarmists make is that the rate of sea-level rise is “accelerating” or rising faster every year.

Sea-level data reported from satellites indicate seas are rising approximately 3.3 mm/year (See Figure 1).

By contrast, tidal stations have recorded a rise of approximately 1 to 2 mm annually, a rate which is little changed over the century or so for which we have adequate records.

Indeed, as reported in Climate at a Glance: Sea Level Rise, the oldest tide gauge in the USA, in New York City, shows no acceleration at all going back to 1850.

Why the large difference?

The answer it turns out is simple. When NASA and NOAA launched new satellites, the data they produced wasn’t the same as the data recorded by earlier satellites.

Figure 1. University of Colorado sea level data, showing the trend and acceleration. Note that the graph shows no overlap between the individual satellite records. SOURCE: UCSLR Group

Citizen scientist Willis Eschenbach obtained NOAA’s Excel spreadsheet showing the full dataset for each of the four satellites. He plotted the NOAA data.

Unlike the Colorado data above, it included the full overlap between the individual satellites. He then looked at the rate of sea-level rise shown by each of the four satellites separately. Figure 2 shows that result.

Figure 2. NOAA sea level data, showing the trend of each of the full individual satellite records and the overall trend. SOURCE: NOAA Excel Spreadsheet

The two most recent satellites record significantly higher rates of sea-level rise than the earlier two satellites. The first two satellites agree quite well, but they both show a much smaller trend than the latter two satellites.

Neither set of the satellite record shows any accelerating trend. The UC scientists simply combined the two dissimilar data sets, plotted a new trend showing acceleration, and didn’t mention the difference.

See the complete analysis here.

This is either incompetent or dishonest and certainly not up to even the simplest of basic science principles.

Virtually any high school or college student who presented such work for a class would get called out on it by their instructor for showing a false trend.

This could explain why former President Barack Obama and Bill Gates felt secure when they each bought oceanfront McMansions.

They proclaim loudly that seas are rising dangerously, but like many climate alarmists, their actions belie their words because they know the data is badly flawed. The data shows seas are not rising at an accelerated rate.

    There is a episode of the Classic 60’s Sci Fi TV series VOYAGE TO THE BOTTOM OF T HE SEA involving Global Warming caused by a Freak Meteor Show igniting the Van Alan Radiation Belt they stop it with Nuclear Missile it was also in the movie that lead to the TV series

    The “adjustments to satellite sea level data started around 2000-2003
    Here we see the 2000 Topex data overlaid on the Jason 1 data.
    The shift is data is very obvious.

    One millimetre per year equals 4 inches over a century. Three millimetres a year equal 12 inches a century. Neither is remotely catastrophic.

    The entire narrative is supported on false pretexts. They build upon each other to create an insanely exaggerated scenario, using the worst imaginable scenario building upon another worst case scenario , building on another worst case scenario. The entire narrative has dodgy premises for the “science” that they refuse to debate. They just brush you off with “the science is settled” or “the debate is over” and cry like babies when you try to make a rational argument.
    These are the tactics of con artists.

    Also, not all ice melt events are the creation of anthropogenic global warming.

    I once watched fifteen minutes of Waterworld.

    That was a quarter of an hour wasted.

    I’m certainly not going to waste any time worrying about the sea level rising one and a half millimetres per annum even for a quarter of a second.

    At that rate, my property won’t be waterfront for a hundred thousand years…

  8. David Lewis says:

    A common trick of the climate change movement is to take number that isn’t alarming and pretend it is a disaster. If it were happening, a sea level rise of 3 mm a year translates to 10.3 inches by 2100. Now consider that they used dishonest means to get the 3 mm a year, and it is obvious that sea level rise isn’t a problem.
