Looking For Acceleration In All The Wrong Places

By Willis Eschenbach – Re-Blogged From WUWT

After considering the tide gauge records around Fairbourne in my last post, I wanted to look at a larger picture. Remember that we’ve been repeatedly told that acceleration in sea level rise is not just forecast, it’s actually occurring. I wrote about some of these claims in my post entitled “Accelerating The Acceleration“. Plus we’ve been deluged, if you’ll excuse the word, with endless cartoons and memes and movies and earnest predictions about the Statue of Liberty going underwater, cities being drowned, islands being overtopped by the sea, and the like. And not only that, but we’re assured that we can see and measure the acceleration in both the tide gauge and the satellite sea-level records.

So I went to get the satellite sea-level records from the University of Colorado. But when I plotted them up, I realized that they stopped in 2018. I couldn’t find anything on their website that explained why. Here’s their data.

NOAA — Straight Talk on Sea Level Rise

By Kip Hansen – Re-Blogged From http://www.WattsUpWithThat.com

The National Oceanic and Atmospheric Administration has some rather useful features on its web site.

One of these is the Tides and Currents which is part of its Center for Operational Oceanographic Products and Services.  Having spent most of the current century living at sea,  with my wife and occasionally a son or our daughter and granddaughter, on our venerable sailing catamaran, the Golden Dawn,   cruising the eastern coast of the United States, the Bahamas, the Turks and Caicos, Hispaniola, and the Spanish, U.S., and British Virgin Islands, I have made extensive use of its features.

Claims of Accelerating Sea Level Rise – Failed

By Larry Hamlin – Re-Blogged From http://www.WattsUpWithThat.com

On June 23, 1988 the Senate Committee on Energy and Natural Resources held a hearing addressing the Greenhouse Effect and Global Climate Change.

Among the presenters at this hearing was Dr. James Hansen, Director, NASA Goddard Institute for Space Studies who introduced his infamous and now debunked global surface temperature model results with future temperature projections under three different scenarios of CO2 emissions growth that grossly over exaggerated resulting projected global temperature increases.

Original Measurement Uncertainty

By Kip Hansen – Re-Blogged From http://www.WattsUpWithThat.com

GRID1_smallIntroduction:

Temperature and Water Level (MSL) are two hot topic measurements being widely bandied about and vast sums of money are being invested in research to determine whether, on a global scale, these physical quantities — Global Average Temperature and Global Mean Sea Level — are changing, and if changing, at what magnitude and at what rate. The Global Averages of these ever-changing, continuous variables are being said to be calculated to extremely precise levels — hundredths of a degree for temperature and millimeters for Global Sea Level — and minute changes on those scales are claimed to be significant and important.

In my recent essays on Tide Gauges, the question of the durability of original measurement uncertainty raised its toothy head in the comments section.

On Sea Level Rise

By Rud Istvan – Re-Blogged From http://www.WattsUpWithThat.com

Background

There is no doubt that interglacials change sea level (SL). And that sea level rise (SLR) can be dramatic on millennial interglacial time scales. That’s what happens when the vast Laurentide ice sheet (among others) melts. But sea level has changed relatively little in the past 7 millennia. We know from archeology that it rose somewhat in the Medieval Warm Period, dropped some during the Little Ice Age, and has been rising slowly since based on tide gauge records. This mostly natural variation is, from 1950-2000, about +1.8mm/year to 2.2mm/year (discrepancy explanation and references follow below). That rate is no cause for alarm. We coped with it for the past century, and can cope with it for the next.

The anthropogenic global warming (AGW) question is whether SLR will accelerate into catastrophic AGW (CAGW) requiring urgent mitigation? Warmunists argue yes, with many alarming images such as National Geographic’s photoshopped Statue of Liberty half submerged (which would require that all of Greenland and Antarctica melts before the next
