The Fantasy of Accelerating Sea Level Rise

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

We’ve been told over an over again that global warming would melt the icecaps, and melt Greenland, and that would result in catastrophic sea level rise flooding cities. We’ve also been told that “sea level rise is “accelerating” but in an investigation done here on WUWT by Willis Eschenbach, Putting the Brakes on Acceleration, he noted in 2011 that there seems to be no evidence of it at all, and notes that sea level was rising faster in the first half of the record.

Weekly Climate and Energy News Roundup #301

Skepticism: In an essay titled “Be Skeptical of Those Who Treat Science as an Ideology” appearing in the Wall Street Journal, Dr. Sue Desmond-Hellmann discusses the difference between anti-science and skepticism, and the difference between denialism and skepticism. As an oncologist, faced with treating patients dying with cancer, Dr. Desmond-Hellmann recognized the importance of honesty and integrity in building trust with her patients. She writes: [Boldface added.]

97% Climate Consensus’ Starts to Crumble

A broad survey of climate change literature for 2017 reveals that the alleged “consensus” behind the dangers of anthropogenic global warming is not nearly as settled among climate scientists as people imagine.

Author Kenneth Richard found that during the course of the year 2017, at least 485 scientific papers were published that in some way questioned the supposed consensus regarding the perils of human CO2 emissions or the efficacy of climate models to predict the future.

SEA LEVEL: Getting a Rise Out of Nothing

By Kip Hansen (with help from Steve Case) – Re-Blogged From http://www.WattsUpWithThat.com

animation_350Prologue:  I have been writing recently about Sea Level Rise, both as particular local examples (  Guam,  Canton,  Miami,   New York, and  NY/NJ  )  and in the series SEA LEVEL: Rise and Fall, of which this is the fourth installment.

How does one get a rise out of nothing?

Let’s see just how R. Steven Nerem, of the CU Sea Level Research Group, manages to pull that trick out of a hat.  According to a report  at Nature.com:

Wandering Thru The Tides

By Willis Eschenbach – Re-Blogged From http://www.WattsUpWithThat.com

I got to thinking about the records of the sea level height taken at tidal stations all over the planet. The main problem with these tide stations is that they measure the height of the sea surface versus the height of some object attached to the land … but the land isn’t sitting still. In most places around the planet the land surface is actually rising or falling, and in some places, it’s doing so at a surprising rate, millimeters per year.

The places that are the most affected, unfortunately, are the places where we have some of the longest tidal records, the northern extra-tropics and northern sub-polar regions. In those sub-polar regions, during the most recent ice age, there were trillions of tonnes of ice on the land. This squashed the land underneath the ice down towards the center of the earth … and as result of that, just like when you squeeze a balloon it bulges out elsewhere, the extra-tropical areas further from the North Pole bulged upwards in response to the northern areas being pushed down.

Sea Level: Rise and Fall – Computational Hubris

Sea Level RiseMeasured from Space?

There have been so many very good essays on Global Sea Level Rise by persons all of whom have a great deal more expertise than I.   Jo Nova hosts a dozen or so excellent essays, which point at another score of papers and publications, for the most part clearly demonstrating that there are two contrarian positions on sea level rise in the scientific community:  1) Sea level has risen, is rising and will continue to rise at a rate approximately 8-12 inches (20-30 centimeters) per century — due to geological and long-term climatic forces well beyond our control;  and 2a) Other than explicit cases of Local Relative SLR, the sea does not appear to be rising much over the last 50-70 years, if at all.  2b) If it is rising due to general warming of the climate it will not add much to position 1.

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.
