Antarctica Sensation: Ice Shelves Surrounding the Continent Grew in Overall Size From 2009-2019

by Chris Morrison
4 June 2023 7:00 AM

The ice shelves surrounding Antarctica grew in overall size during the 11 years to 2019, according to dramatic new evidence published by three climate scientists from the University of Leeds. The growth was significant with overall shelf area increasing by 5,305 km2, adding 0.4% to the total shelf area in the 11 years under review. The paper has just been published by the influential European Geosciences Union, but it raises questions within the ‘settled’ climate science narrative, so it is highly unlikely to be covered by mainstream media

The Leeds researchers looked at satellite data to measure the annual calving position and area of 34 ice sheets accounting for 80% of the Antarctica coastline. They found reductions in the area on the Antarctica Peninsula and West Antarctica of 6,693 km2 and 5,563 km2 respectively were outweighed by growth in East Antarctica of 3,532 km2 and 14,028 km2 in the large Ross and Ronne-Filchner ice shelves. The largest retreat occurred on the Larsen C shelf when 5,917 km2 was lost in a single calving event that made alarmist headlines around the world. The largest increase, noted in slightly less media detail, was the 5,889 km2 advance on the Ronne platform.

Ice shelves around the coast of Antarctica play an important role in the cycle of ice production since they often buttress the glaciers behind them. Remove the plug and glaciers can move at a faster rate towards the coast. The shelves show considerable natural variation allowing alarmists to cherry-pick significant collapses into the sea to promote a hypothesis that the overall climate is breaking down. Typical of this coverage was an article by BBC science correspondent Jonathan Amos in 2021 under a ‘climate change’ heading, noting, “The Antarctic ice shelf in the line of fire.” In 2017, i News reported comments broadcast by Sir David Attenborough said to warn that “Antarctica’s melting ice sheets could flood London by end of century”.

The above map displays the ice shelf areas in blue that have increased in size and colours in red those that have decreased. The two large blue areas are the Ross and Ronne-Filchner areas. Little loss is shown over the east of the continent with deficits concentrated in the West. In total, 18 ice shelves are said to have retreated and 16 larger platforms have grown in area. Overall, the shelves gained 661 giga tonnes of mass over the decade. The scientists note that using a ‘steady’ state process, by which they mean no change in any variable, would produce an estimate of substantial loss over the period. They argue their work demonstrates the importance of using “time-variable calving flux observations to measure change”.

In short, and in less scientific terms, check actual observations, and ignore make-believe computer models, and the resulting stories published by climate alarmists promoting the collectivist Net Zero project.

It is not a surprise that ice shelves are currently thinning in parts of West Antarctica. The area is riddled with buried volcanos, with the recent discovery of another 91 bringing the known total to 138. Across the West Antarctica Rift System, their heights range from 300-12,600 ft. In addition, areas around the Thwaites-Pine Island-Pope glacier have a thin Earth crust causing one group of scientists to note that the “elevated geothermal heat flow band” is exerting a “profound influence on the flow dynamics of the Western Antarctica Ice Sheet”.

On a number of occasions, the Daily Sceptic has referenced the recent work of Singh and Polvani that shows current warming only in that part of the continent. Over the last seven decades, warming across Antarctica has been “nearly non-existent”, they point out. The surrounding sea ice extent has “modestly expanded”. Over at NASA, scientists have estimated any overall sheet ice loss at 0.0005% a year.

Last year, Adjunct Professor J. Ray Bates at the University College Dublin wrote a paper entitled ‘Polar Sea Ice and the Climate Catastrophe Narrative’. In the Antarctic, the meteorologist observed, there has been “no significant” change in the annual mean sea ice extent since reliable satellite measurements began. This is despite climate model predictions of a decline.

He published the above graph which showed the extent of sea ice from 1979 to 2021 along the horizontal axis. Contrary to what the models projected, the trend during this period at the September late-winter maximum is in the direction of a slightly increasing Antarctica sea ice extent. Professor Bates concludes that climate models failed to predict the growth in Antarctica sea ice, and they have missed the recent marked slowdown of sea ice decline in the Arctic. “It would be unwarranted to think they are going to get it right over the next 30 years,” he said.

He concludes: “These facts deserve to be recognised when the notion of a climate emergency, requiring the most drastic and immediate changes to the world’s economy, is being put forward. Some concern might also be shown among those involved for the increasing eco-anxiety being inflicted on the younger generation.”

Does anyone else find it odd that we are re-introducing beavers because their dams reduce flooding, whilst removing dams because they interfere with nature?

It’s not odd. It is because greens are not very clever. They are a product of the past 50 years of apalling tertiary education. Also this is normally what happens when you have female stem graduates in charge of stuff. Sack them all

Whenever Imperial College is mentioned as a source of data early in the story, you know where it’s heading.

Spain has been leading Europe’s dam removal programme, with 108 dams taken down alone in 2021, and an estimated 200 dams removed from its rivers in total since the EU’s Water Framework Directive was issued: https://expose-news.com/2024/11/06/are-dam-removal-projects-the-cause/.

GREEN Politics is destroying the western world. We can see the almighty mess Germany has got itself in. The UK now has the highest electricity prices in the entire world and everywhere Greens go they leave a trail of destruction in their wake. They are a a pseudo-scientific fraud and motivated entirely by ideology that uses the environment and the planet as the excuse for every one of their policies, which amount to Central Planning and total control of every aspect of people’s lives (Communism) and the photo above shows us the result. ——These people are being booted out now in Germany and only when the entire world gets rid of this garbage can we all start to flourish and live normally free from this tyranny. ——Here in the UK we unfortunately are heading in the wrong direction (as usual) but Miliband and Labour must be removed before our mothers freeze to death in their house and the blackouts come thick and fast.

Same as the “unprecedented” flooding of the Somerset Levels a decade ago.

It was only unprecedented in the sense that there were no official records of the extent of flooding before Civil Engineering and the Levels were drained.

The Eco Nutters at the Environment Agency thought it was a good idea not to dredge the drainage channels in the interests of prioritising and protecting wildlife …. most of which drowned when the floods occurred.

And remember some farmer in Herefordshire who dredged a river, and saved local houses from being flooded, the busy-body Council took legal action against him. Can’t have independent people looking after locals can we!

Ben, is it or is it not true that a number of flood-control dams in the Valencia catchment have been de-commissioned for environmental reasons?

I went to Valencia a few years ago and the town was very proud of their solution to constant flooding that used to happen on a regular basis. They diverted the river that ran through the centre of town and made the river bed into a park.

This brief article from 2012 explains the scheme.

https://metropolismag.com/projects/how-valencia-turned-crisis-river-into-park/

I wonder if the removal of dams upstream then affected this scheme in unimaginable, or at least un-modeled ways?

It seems to be standard practice in climate modelling to add uniformly distributed noise to some of the continuous variables. This is the only application I’ve heard of in scientific simulation and I’ve never seen anything but a hand waving justification. As Einstein might have said, God does not play die.

A lot of towns in the hilly area of Valencia are built in river valleys, flooding has happened before and will happen again,very rarely reported until now, a point completely ignored by the likes of the BBC

“… are in the grip of a movement that requires the demolition of dams. On that bizarre green view, dams degrade society’s relationship with nature.”

The same movement wants us to build dams to provide pumped storage to solve the problem of unsustainable, unreliable, intermittent wind/solar power.

Funny old World.

If anyone is interested, please read Professor Willie Soon, an astrophysicist. He explains very clearly, there is no man made climate change. Watch his interview on X with Tucker Carlson, if you are interested in the truth about “climate change”.

Most on this list are converts. The problem is how to get his and many other similar messages out into and accepted by the majority of the global population.

This Green ideology is basically the return of Paganism. If something goes wrong, it is because we have displeased the gods of the natural world.

Our world has turned its back on Christianity and re-embraced the primitive religion that Boadicea would have respected and probably followed. See The Wicker Man for further details.

So dams are wholly unnatural, engineered artefacts of culture.

But wind turbines and solar farms aren’t?

At least dams are nominally functional and worthwhile.
