It’s a very good thing that climate does not pay attention to “climate scientists”

Perhaps I will heed the climate charlatans a little more when they abandon the practice of religious orthodoxy, regenerate their sense of inquiry and return to a proper process of science.

Glacier National Park Quietly Removes Its ‘Gone by 2020’ Signs

May 30, 2019. St. Mary, Montana.

Officials at Glacier National Park (GNP) have begun quietly removing and altering signs and government literature which told visitors that the Park’s glaciers were all expected to disappear by either 2020 or 2030.
In recent years the National Park Service prominently featured brochures, signs and films which boldly proclaimed that all glaciers at GNP were melting away rapidly. But now officials at GNP seem to be scrambling to hide or replace their previous hysterical claims while avoiding any notice to the public that the claims were inaccurate. Teams from Lysander Spooner University visiting the Park each September have noted that GNP’s most famous glaciers such as the Grinnell Glacier and the Jackson Glacier appear to have been growing—not shrinking—since about 2010. (The Jackson Glacier—easily seen from the Going-To-The-Sun Highway—may have grown as much as 25% or more over the past decade.)

…. As recently as September 2018 the diorama displayed a sign saying GNP’s glaciers were expected to disappear completely by 2020. ……. But at some point during this past winter (as the visitor center was closed to the public), workers replaced the diorama’s ‘gone by 2020’ engraving with a new sign indicating the glaciers will disappear in “future generations.” Almost everywhere, the Park’s specific claims of impending glacier disappearance have been replaced with more nuanced messaging indicating that everyone agrees that the glaciers are melting. Some signs indicate that glacial melt is “accelerating.” ……. 

Last year the Park Service quietly removed its two large steel trash cans at the Many Glacier Hotel which depicted “before and after” engravings of the Grinnell Glacier in 1910 and 2009. The steel carvings indicated that the Glacier had shrunk significantly between the two dates. But a viral video published on showed that the Grinnell Glacier appears to be slightly larger than in 2009.

The ‘gone by 2020’ claims were repeated in the New York Times, National Geographic, and other international news sources. But no mainstream news outlet has done any meaningful reporting regarding the apparent stabilization and recovery of the glaciers in GNP over the past decade. 

It is not that climate does not change. Of course it does. It always has. It always will. It is the semi-religious claims that make climate “scientists” charlatans.


Alarmists wail – “Collapse” of Antarctic ice is nigh (but it could take 1000 years)

May 13, 2014

There is much wailing and gnashing of teeth.

The headlines would suggest an impending catastrophe. The Western Atlantic ice sheet is “collapsing”. Sea level could rise 1.2m.

The end of the world is nigh. And it is all due to global warming!!

Yes indeed – except that the melting has been going on for centuries. The so called “collapse” may take upto 1,000 years! Measurements over 9 years are projected over a millenium. Computer models have forecast that the loss of the glaciers is unstoppable and will occur sometime in the next 1,000 years.

The Guardian: Western Antarctic ice sheet collapse has already begun, scientists warn

BBC: ‘Nothing can stop retreat’ of West Antarctic glaciers

A collapse in very slow motion!

The alarmist headlines are are based on two papers. Note that one is based on 9 years of measurement and the other is a computer forecast about a “collapse” that is potentially underway.

AbstractWe measure the grounding line retreat of glaciers draining the Amundsen Sea Embayment of West Antarctica using Earth Remote Sensing (ERS-1/2) satellite radar interferometry from 1992 to 2011. Pine Island Glacier retreated 31 km at its center, with most retreat in 2005–2009 when the glacier un-grounded from its ice plain. Thwaites Glacier retreated 14 km along its fast-flow core and 1 to 9 km along the sides. Haynes Glacier retreated 10 km along its flanks. Smith/Kohler glaciers retreated the most, 35 km along its ice plain, and its ice shelf pinning points are vanishing. These rapid retreats proceed along regions of retrograde bed elevation mapped at a high spatial resolution using a mass conservation technique (MC) that removes residual ambiguities from prior mappings. Upstream of the 2011 grounding line positions, we find no major bed obstacle that would prevent the glaciers from further retreat and draw down the entire basin.

2. Ian Joughin, Benjamin E. Smith and Brooke Medley,  Marine Ice Sheet Collapse Potentially Underway for the Thwaites Glacier Basin, West AntarcticaScience,     DOI: 10.1126/science.1249055

Abstract: Resting atop a deep marine basin, the West Antarctic Ice Sheet has long been considered prone to instability. Using a numerical model, we investigate the sensitivity of Thwaites Glacier to ocean melt and whether unstable retreat is already underway. Our model reproduces observed losses when forced with ocean melt comparable to estimates. Simulated losses are moderate (<0.25 mm per year sea level) over the 21st Century, but generally increase thereafter. Except possibly for the lowest-melt scenario, the simulations indicate early-stage collapse has begun. Less certain is the timescale, with onset of rapid (> 1 mm per year of sea-level rise) collapse for the different simulations within the range of two to nine centuries.


The Antarctic glaciers may well be retreating (as glaciers are often wont to do), but Antarctic ice cover is at an all time high and the processes being forecast are being projected over millenia. And there is absolutely no evidence that these processes have anything whatever to do with any man-made effects. That connection is inferred  or assumed.
