Hockeystick Redux Chapter Fortyleven

Guest Post by Willis Eschenbach [See update at the end] Since publishing my last two posts here and here on the Church and White (“C&W”) 2011 sea level dataset, some folks have queried why I didn’t use the Church and White 2013 dataset instead. The answer is simple. It’s because of the hockeystick. What hockeystick, you…

The Climate of Gavin

Guest Post by Willis Eschenbach Gavin Schmidt, who I am given to understand is a good computer programmer, is one of the principals at the incongruously named website “RealClimate”. The name is incongruous because they censor anyone who dares to disagree with their revealed wisdom. I bring this up because I’m on Twitter, @WEschenbach. You’re…

Sea level trends, starting points, and datum shifts

A tide gauge record must always start about the time of low ENSO waters and possibly include a datum shift Guest essay by Albert Parker In addition to the case of Aden, discussed in Parker & Ollier (2017) and Parker & O’Sullivan (2018), that is only one of the many where the data proposed by…

Errorless Global Mean Sea Level Rise

Brief Comment by Kip Hansen   Have you ever noticed that whenever NASA or NOAA presents a graph of satellite-era Global Mean Sea Level rise, there are no error bars?  There are no Confidence Intervals?  There is no Uncertainty Range?   In a previous essay on SLR, I annotated the graph at the left to show…

NOAA — Straight Talk on Sea Level Rise

Guest Essay by Kip Hansen   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…

Sea Level to Rise by 1.2 Metres by 2300 – So What?

Guest essay by Andi Cockroft Firstly let me say that I am not one of the most technical writers you will see here. I regard myself pretty much as a layman despite studying Geology, Mathematics and Computer Science at University. So you won’t find all the references to papers (well not many), nor exact scientific…

Claim: Global Sea Level Rise is Accelerating

There’s been a lot of buzz about this new paper from Nerem et al (see link in references below) where they claim to find global sea level rise acceleration over the past 25 years. I provide this article from NASA Earth Observatory for context for some posts that are coming later. Adjustments to data figure…

Do rising temperatures cause rising sea levels?

Guest essay by Philip Lloyd There is a general belief that the observed sea level rise of about 1.5mm per year (according to tide gauges) and 3mm per year (from satellite measurements) is partly due to heating of the oceans and their consequent expansion. If, however, you look at the estimates of sea temperatures, you…

The fantasy of accelerating sea level rise just got hosed

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…

Soi Cowboy, a red light district in Bangkok.

Claim: Bangkok Brothels Causing the Thai Capital to Sink

Guest essay by Eric Worrall Illegal pumping of raw groundwater for soapy massages blamed for subsidence. SINKING FEELING Bangkok could be partly submerged by 2030 because ‘soapy massage’ brothels are stealing groundwater causing the city to SINK Thai cops have raided several ‘mega-brothels’ in the low-lying city which they believe are illegally siphoning groundwater By…

Wandering Thru The Tides

Guest Post by Willis Eschenbach 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…

Fiji ‘Flooding’ is Fake News from #COP23

Open Letter to Honorable Prime Minister of Fiji and President of COP23 Frank Bainimarama by Nils-Axel Mörner Mr. President, The community assembled at the COP23 meeting in Bonn badly wants temperature to rise according to models proposed (but never verified, rather seriously contradicted) and sea level changes that may pose serious flooding threats to low lying coasts provided…

More Pacific island #COP23 Opportunism

Guest essay by John McLean Barry Brill’s report on Fiji’s relocation of a village doesn’t mean that it’s the only opportunistic Pacific island country when it comes to COP23. It’s near neighbour, Kiribati, is likewise trying to get its hands on some of that money to reimburse it for the NZD10 million paid to Fiji…

SEA LEVEL: Rise and Fall – Part 1

Guest Essay by Kip Hansen In remembrance of the victims of Hurricanes Harvey and Irma:  I have held off publishing this essay until after the damage from Hurricane Irma could be determined hoping not to add to the fears, angst and now sorrow experienced by both victims and their relatives.  My prayers and sympathy go…

Public Release: 17-Aug-2017 Study validates East Antarctic ice sheet to remain stable even if western ice sheet melts Indiana University   INDIANAPOLIS — A new study from Indiana University-Purdue University Indianapolis validates that the central core of the East Antarctic ice sheet should remain stable even if the West Antarctic ice sheet melts. The study’s…

Trump To Repeal Obama Executive Order On Sea Level Rise

Energy From The Daily Caller Michael Bastasch President Donald Trump will rescind an Obama administration policy requiring government agencies to take into account global warming-induced flooding and sea level rise for federally-funded projects. Trump will repeal the climate order that President Barack Obama signed in 2015 as part of a broader effort to streamline infrastructure…

When The Model Models Itself

Guest Post by Willis Eschenbach Eric Worrell posted an interesting article wherein a climate “scientist” says that falsifiability is not an integral part of science … now that’s bizarre madness to me, but here’s what she says: It turns out that my work now as a climate scientist doesn’t quite gel with the way we…

No longer water under the bridge, statistics yields new data on sea levels

From Eurekalert Public Release: 8-Aug-2017 Untraditional approach expected to save lives, businesses, and communities along East Coast shows rate accelerating at a pace in contrast to previously accepted data American Statistical Association ALEXANDRIA, Va. (August 8, 2017) – While the scientific community has long warned about rising sea levels and their destructive impact on life,…

Putting the Brakes on Satellite Acceleration

Guest Post by Willis Eschenbach I discussed acceleration in the tide gauge records in a previous post. However, people are also claiming that either there is acceleration in the satellite record or there will soon be acceleration. So I thought I’d take a look at the satellite-measured sea level question. First, here’s the satellite data:…

Who’s Afraid of Sea-Level Acceleration?

by Joe Born This is kind of a coda to Willis Eschenbach’s recent post about sea-level rise. In that post Mr. Eschenbach argued against confidence in the recently observed accelerations’ reality. His post was characteristically compelling. But there’s a sense in which the question of whether apparent acceleration is real seems secondary to whether the…

Study: Sea Level Rise Revised Downward

Reposted from Roy Spencer’s Blog July 21st, 2017 by Roy W. Spencer, Ph. D. If I had not looked past the headline of the press report on a new study, I would have just filed it under “It’s worse than we thought”. A new study in Nature reported on July 17 carried the following headlines:…

Sea Level Rise Accelerating? Not.

Guest Post by Willis Eschenbach (NOTE UPDATE AT END) There’s a recent and good post here at WUWT by Larry Kummer about sea level rise. However, I disagree with a couple of his comments, viz: (b) There are some tentative signs that the rate of increase is already accelerating, rather than just fluctuating. But the…

More Fun With Sea Level

The Permanent Service for Mean Sea Level (PSMSL) is perhaps the best source for sea level data. Established in 1933, the Permanent Service for Mean Sea Level (PSMSL) has been responsible for the collection, publication, analysis and interpretation of sea level data from the global network of tide gauges. It is based in Liverpool at…

Closely Coupled: Solar Activity and Sea Level

Guest essay by David Archibald From a post a couple of days ago: “an F10.7 flux above 100 causes warming and below that level causes cooling.” Greg asked “Can you prove that?” I already had in this WUWT post from 2012. But it is worth revisiting the subject because it answers the big question –…

Alarmists Gone Wild: “Alarmist CO2 Headlines Create Confusion”… Particularly When Accompanied by Sea Level Alarmism.

Guest post by David Middleton Real Clear Science and Real Clear Energy are great aggregators of science and energy articles.  But, invariably, there is always at least one article that merits lampooning, if not outright ridicule… And today was no exception. Tuesday, May 16 Solar and Batteries Double Cost of Electricity Science 2.0 Earth’s Giant…

@NPR Bungles Sea Level Rise Story

Supposed threats to coastal military installations ignore science By Bob Endlich “Data from CO2 measuring stations and from the Sewell’s Point and all other tide gages may clearly refute these assertions, but NPR and its colleagues will not change their minds.” “The Sewell’s Point tide gage shows that the rate of sea level rise has…

Guangzhou Rising – Canton Sinking

Guest Essay by Kip Hansen The New York Times seems to be running short of environmental journalists.  Its latest salvo in the attempt to keep climate change at the forefront of American minds was written by Michael Kimmelman.  “Who?”  you ask. Micheal Kimmelman, the current architecture critic of The New York Times.  (But, rest assured,…

Mainstream Media Ignores New Study: Present Sea Surface Temperatures “Indistinguishable” From Those During Last Interglacial…

…When Sea Levels Were Roughly 20 to 30 Feet Higher than Today Guest Post by Bob Tisdale Science recently published Hoffman, et al. (2017) Regional and global sea-surface temperatures during the last interglaciation. Not too surprisingly, the study has been ignored by the mainstream media. Why? As Science writes in their summary (my boldface): Sea…

NOAA Jumps The Shark In Tampa Bay

Guest Post by Willis Eschenbach [see Update at the end] I thought I might write about how I research a subject. Over at Dr. Judith’s excellent website, she periodically puts out a list of interesting papers that she has come across. This time it was “Week In Review: Water Edition”. She gave a link to…

Another phony L A Times Florida sea level rise acceleration article

Guest essay by Larry Hamlin The L A Times seems to be addicted to publishing scientifically unsupported  climate alarmist articles regarding supposed sea level rise acceleration in Florida. Just last September the Times published an article on this same topic which was exposed as nothing but climate alarmist propaganda (https://wattsupwiththat.com/2016/09/19/l-a-times-climate-science-denial-article-instead-shows-the-times-clearly-denying-well-established-climate-science/). This most recent Times article…

The Ninth First Climate Refugees

Guest Post by Willis Eschenbach [see update] Well, the claims of the “first climate refugees” are coming up again. I think we’re up to the ninth first climate refugees, it’s hard to keep track. In any case, I came across this: International leaders gathering in Paris to address global warming face increasing pressure to tackle…

Eye roller: we measured sea levels in the wrong places, therefore it’s ‘worse than we thought’

From the UNIVERSITY OF HAWAII AT MANOA Historical records may underestimate global sea level rise New research published in Geophysical Research Letters shows that the longest and highest-quality records of historical ocean water levels may underestimate the amount of global average sea level rise that occurred during the 20th century. Dr. Philip Thompson, associate director…

L.A. Times climate science denial article instead shows the Times clearly denying well established climate science

The L. A. Times published an article claiming that “Trump’s climate science denial clashes with the reality of rising seas in Florida” The article fails to address easily available and comprehensive NOAA tide gauge data updated through the year 2015 (http://tidesandcurrents.noaa.gov/sltrends/sltrends_us.htm) showing that the Florida coastline is experiencing no acceleration in coastal sea level rise…
