Claim: Sea level rise from ice sheets track worst-case climate change scenario

by University of Leeds, September 1, 2020 in WUWT/Nature


Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching the Intergovernmental Panel on Climate Change’s worst-case climate warming scenarios.

So far, global sea levels have increased in the most part through a mechanism called thermal expansion, which means that volume of seawater expands as it gets warmer. But in the last five years, ice melt from the ice sheets and mountain glaciers has overtaken global warming as the main cause of rising sea levels.

Dr Ruth Mottram, study co-author and climate researcher at the Danish Meteorological Institute, said: “It is not only Antarctica and Greenland that are causing the water to rise. In recent years, thousands of smaller glaciers have begun to melt or disappear altogether, as we saw with the glacier Ok in Iceland, which was declared “dead” in 2014. This means that melting of ice has now taken over as the main contributor of sea level rise. “

ANTARCTIC SEA ICE EXTENT IS CURRENTLY EXCEEDING THE 1981-2010 AVERAGE BY 233,000 KM2, AND GROWING!

by Cap Allon, August 30, 2020 in Electroverse


Climate alarmists take note: the ice locked within Antarctica is far more important to your hokey climate change theories than that which is contained in its northern cousin, the Arctic; the southern pole contains 90% of Earth’s ice.

According to official government data from the National Snow & Ice Data Center (NSIDC), 2020’s Antarctic Sea Ice Extent has been increasing rapidly this month, to levels rarely seen since record-keeping began 4+ decades ago.

The latest data-point –from day 241 (or Aug 28)– reveals extent is currently standing at 18.354 million km2, compared with the 1981-2010 ‘day 241’ average of 18.131 million km2 — and by my crude calculations, that’s an AGW-destroying 233,000 km2 more:

According to official government data from the National Snow & Ice Data Center (NSIDC), 2020’s Antarctic Sea Ice Extent is tracking the 1979-1990 average.

Climate alarmists take note, the ice locked within Antarctica is far more important to your hokey climate theories than that contained in its northern cousin the Arctic.

The Antarctic contains 90% of our planet’s ice, and, therefore, if Antarctica isn’t melting then any potential sea-level rise will be severely limited.

And Antarctica isn’t melting.

According to the latest NSIDC data, sea ice extent around the southern pole has been tracking the 1979-1990 average ALL YEAR:

In addition, August 2020’s extent is currently greater than it was in the 1980s:

DESPITE THE LIES, THE SPIN, AND THE PROPAGANDA, ANTARCTIC SEA ICE IS GROWING — BOTH EXTENT AND CONCENTRATION GREATER NOW THAN IN 1980

by Cap Allon, July 6, 2020 in Electroverse


The UN and their scraggly little offshoot, the IPCC, are at it again — obfuscating data in order to push their fraudulent catastrophic global warming agenda.

According to the IPCC, and picked up the usual AGW propaganda rags such as the Guardian: “the South pole is warming three times faster than rest of the world.”

The Guardian articledated June 30, 2020 continues in predictably befogging fashion: “Dramatic change in Antarctica’s interior in past three decades a result of effects from tropical variability working together with increasing greenhouse gases.”

But, 1) the MSM have a habit of claiming everywhere is warming faster than everywhere else:

And 2), the actual data reveals quite the opposite re Antarctica.

As @Harry_Hardrada recently pointed out on Twitter, there was a larger extent and concentration of Antarctic Sea Ice in June 2020 than back in June 1980:

Robert Felix over at iceagenow.com dives into the data, adding that sea ice extent today stands at 700,000 sq km (270,272 sq miles) greater than in 1980.

And in case you’re having a hard time reading the numbers, Felix breaks them down for you:

Sea ice extent in June 2020 = 13.2 million sq km
Sea ice extent in June 1980 = 12.5 million sq km

Sea ice concentration in June 2020 = 10.6 million sq km
Sea ice concentration in June 1980 = 9.6 million sq km

Fact-checked!

That’s enough extra ice to entirely cover Maryland, Delaware, West Virginia, South Carolina, Virginia, Indiana, Ohio and all six New England states. Oh, and throw in Washington, D.C. for good measure. (Which might be a good idea.)

A “Good” Proxy on the Antarctic Peninsula?

by Steve McIntyre, June 30, 2014 in ClimateAudit


Nearly all of the text of this article on an interesting ice core proxy series (James Ross Island) from the Antarctic Peninsula was written in June 2014, but not finished at the time for reasons that I don’t recall.  This proxy was one of 16 proxy series in the Kaufman 12K pdf. 60-90S reconstruction.

I originally drafted the article because it seemed to me that the then new James Ross Island isotope series exemplified many features of a “good” proxy according to ex ante criteria that I had loosely formulated from time to time in critiquing “bad” proxies, but never really codified (in large part, because it’s not easy to codify criteria except through handling data.)

Although this series is in the Kaufman 60-90S reconstruction, its appearance is quite different than the final 60-90S reconstruction: indeed, it has a very negative correlation (-0.61) to Kaufman’s final CPS reconstruction. I’ll discuss that in a different article.

Following is mostly 2014 notes, with some minot updating for context.

“Good” Proxies
I’ve articulated with increasing clarity over the years (but present in early work as well) – is that one needs to work outward from proxies that are “good” according to some ex ante criteria, rather than place hope in a complicated multivariate algorithm on inconsistent and noisy data, not all of which are “proxies” for the item being reconstructed. This is based on principles that I’ve observed in use by geophysicists and geologists to combine “good” (high resolution) data with lower quality data.

A HISTORY OF THE ADVANCE AND RETREAT OF ALPINE GLACIERS

by Cap Allon, June 23, 2020 in Electroverse


It should be obvious after watching that glacial advances and retreats have always occurred and that they must therefore be the result of natural forcings.

On the back of decades of historically high solar activity, modern human’s witnessed a gradual glacial melt. But now, the Sun is once again shutting down, and the evidence for a return to glacial advance is ever-building:

The Greenland Ice Sheet continues to gain record amounts of snow & ice:

 

Natural Variability Behind West Antarctic Warming—Media Silent

by D. Whitehouse, June 19,2020 in ClimateChangeDispatch


Ten days ago the journal Science issued an embargoed press release about a forthcoming paper that suggested the warming observed in West Antarctica was due to natural climatic variability.

West Antarctica has always been looked on by alarmists as being the southern example of polar temperature amplification – a phenomenon predicted by most climate change models.

The Arctic temperature amplification is very apparent so there must be an Antarctic equivalent, and there it is.

But while scientists have been well aware that Antarctica is warming asymmetrically, with West Antarctica experiencing more than East Antarctica and frequently attributed to climate change, the underlying causes of this phenomenon have been poorly understood, and the suggestion that West Antarctica may be experiencing natural warming has been suggested before though not taken up very enthusiastically, if at all.

This new paper, “The internal origin of the west-east asymmetry of Antarctic climate change”, expresses the dilemma well.

The Yin and Yang of Holocene Polar Regions Andy May / 1 day ago May 27, 2020

by R. Hannon/A. May, May 27, 2020 in WUWT


Introduction

The Arctic and Antarctic regions are different and yet similar in many ways. The Arctic has ocean surrounded by land and the Antarctic is a continent surrounded by water. Both are cold, glaciated and located at Earth’s poles some 11,000 miles apart. While sea ice has been retreating in the Arctic, it has been relatively stable in the Antarctic. This post examines surface temperature trends, solar insolation, and CO2 at the polar Arctic and Antarctic regions during the Holocene interglacial period.

A newly released paper by Kumar et al looks at the changes and prediction of the Amery Ice Shelf (AIS) of East Antarctica using remote sensing data.

The scientists found that the ice shelf is prograding (expanding), and not breaking apart like some alarmist scientists feared earlier.

Claim: Antarctic Sea Ice Growth Caused by Meltwater

by Eric Worrall, May 7, 2020 in WUWT


According to climate scientists, less dense meltwater on the surface of the Antarctic ocean reduced convection between the surface and ocean depths, leaving heat trapped in the depths.

Don’t you love climate science? When sea ice accumulates, scientists adjust the models until they get the right result. When the sea ice melts, well that is what you would expect from global warming.

L’Antarctique géologique (2/2)

by A. Préat, 1 mai 2020 in ScienceClimatEnergie


Cet article fait suite aux trois récents articles publiés par le Prof. Maurin sur SCE (1/3, 2/3,  3/3), et traite de l’évolution géologique de la plaque Antarctica.
Voir également L’Antarctique géologique (1/2).

3/ Situation récente à l’échelle géologique

3.1. Isolation de la plaque Antarctique

Nous arrivons ainsi à la situation actuelle avec l’Arctique et l’Antarctique, situation décrite dans les parties 1 à 3 des articles de M. Maurin (parties 1/3, 2/3 et 3/3). D’où proviennent les glaciations actuelles ? Pour les comprendre il faut remonter au début de l’ère cénozoïque en considérant l’Antarctique qui était en position polaire (Scotese, 2001).

La plaque antarctique, partie intégrante de l’ensemble des continents formant le Gondwana est entourée dès le Jurassique (Figs. 7 et 12, inL’Antarctique géologique 1/2) de rides médio-océaniques (excepté la péninsule antarctique qui provient d’une limite de plaque convergente active avec failles transformantes séparant la plaque Antarctique et la plaque Scotia). En conséquence, la plaque Antarctique est actuellement en expansion par rapport aux plaques adjacentes, et fut particulièrement stable et isolée par rapport aux événements tectoniques du Mésozoïque et du Cénozoïque (ici).

Dans ce contexte, et en remontant le temps, il faut noter l’individualisation, dès l’Ordovicien, de la péninsule antarctique avec des montagnes de plus de 3200 m d’altitude constituant aujourd’hui la région la plus au nord de l’Antarctique occidental et s’étendant au-delà du cercle polaire. Cette chaîne de montagnes prolonge les Andes de l’Amérique du Sud dans la continuité d’une dorsale sous-marine caractérisée par un gradient géothermique élevé (voir plus loin). Ainsi on voit que l’Antarctique, depuis longtemps et encore aujourd’hui, participe à un jeu de tectonique des plaques encore active avec des effets locaux (notamment variations du  gradient géothermique).Ce gradient géothermique est un élément important à prendre en considération dans la dynamique glaciaire car il favorise la fonte et ensuite le glissement des glaces.

Notons que Arctowski (in Fogg 1992) avait déjà suggéré en 1901 que les Andes étaient présentes dans la pointe nord de la péninsule antarctique (Graham Land) .

Cet article traite de l’évolution géologique de la plaque Antarctica, et fait suite aux trois récents articles publiés dans SCE par le Prof. Maurin sur la cryosphère actuelle (1/3, 2/3,  3/3).

1/ Les glaces fascinent …

Les glaces fascinent depuis longtemps les climatologues qui y voient un monde à part, aujourd’hui elles sont suivies ‘à la loupe’ car elles témoigneraient en tout ou en partie du processus de réchauffement actuel. Elles sont l’objet d’une attention médiatique constante. Pourtant elles furent souvent absentes de la Planète, elles apparurent plusieurs fois et disparurent autant de fois au cours de l’histoire géologique, le plus souvent suivant des modalités différentes à l’échelle temporelle et spatiale.

Il n’est pas possible ici de retracer la longue histoire des glaces qui commence au Précambrien, au moins à la transition Archéen et Protérozoïque (avec la glaciation huronienne, il y a environ 2,4 Ga, pour l’échelle détaillée des temps géologiques voir ici, et ci-dessous (Fig. 1) pour une version simplifiée) et se poursuit avec des aléas divers avec un recouvrement des glaces sur l’ensemble de la Planète à la fin du Néoprotérozoïque, donc y compris dans la zone équatoriale, donnant lieu au fameux ‘Snowball Earth’ ou hypothèse de la Terre boule de neige ou encore ‘Terre gelée’ (glaciation marinoenne qui a fait suite à la -ou les ? glaciation(s) sturtienne(s)- il y a 635 Ma. Ensuite viendra la glaciation Gaskiers vers 580 Ma, c’est-à-dire vers la fin du Précambrien. Cet épisode marinoen d’englacement généralisé perdura plus d’une dizaine de millions d’années avec des calottes de glace sur l’équateur (ici) et est à l’origine du nom de l’avant-dernière période du Précambrien, à savoir le Cryogénien (partie supérieure du Protérozoïque entre 850 Ma et 635 Ma, cf. Fig. 1). Entre ces deux grandes glaciations précambriennes (celles de l’huronien et du marinoen), soit sur un peu plus de 1,5 Ga  aucune autre glaciation n’a encore? été rapportée, ce qui supposerait que pendant cet intervalle de temps le climat s’est maintenu dans des conditions plutôt chaudes, avec une régulation thermique ‘sans faille’ (Ramstein, 2015). Notons également pour être complet la présence de glaciers locaux à 2,9 Ga dans l’Archéen d’Afrique du Sud (glaciation ‘pongolienne’) (ici).

Denman Glacier–Latest Antarctic Meltdown Scare

by P. Homewood, March 24, 2020 in NotaLotofPeopleKnowThat


Scientists have found a new point of major vulnerability in the Antarctic ice sheet, in a region that already appears to be changing as the climate warms and has the potential to raise sea levels by nearly five feet over the long term.

Denman glacier, in East Antarctica, is a 12-mile-wide stream of ice that flows over the deepest undersea canyon in the entire ice sheet before spilling out into the ocean. That subsea trough is more than 2 miles deep, or double the average depth of the Grand Canyon. While there are far deeper trenches in the open ocean, such as the Marianas Trench, in this case the extreme undersea topography lies right on the outer fringe of the Antarctic continent — making it the “deepest continental point on Earth.”

In reality the scientists who wrote this study do not have a clue whether the retreat of the Denman is anything new or not, or whether the deep ocean temperatures are any warmer than before 1979. Or whether what they are observing is just a natural process.

 

We can then go on to explore sea level implications.

They claim that since 1979, 250 billion tonnes of ice has been lost, equivalent to 0.5mm of sea level rise. In other words, 1.3mm/C, hardly cataclysmic.

They then go on to talk about a potential loss of 540 trillion tonnes, raising sea levels by 5 feet. Yet at current rates, it would take 86400 years for this to occur!

As always with these sort of studies, the authors refuse to say how long all this will take to happen.

 

ANTARCTICA JUST SET ITS COLDEST MARCH TEMPERATURE ON RECORD: A “GLOBAL WARMING” DESTROYING -75.3C (-103.5F)

by Cap Allon, March 23, 2020 in Electroverse


The MSM has a blatant warm-bias, that’s been clear for years…

A myriad of news outlets were all-too-happy to run with the Antarctic Peninsula’s record warm temperature last month, painting it as further evidence of the coming climate catastrophe (despite the peninsula actually being located closer to Argentina than the South Pole, and the event officially going down as a foehn). But where are those same rags now? Where is their balance? Their credibility? Or is informing the public not the goal anymore, is their mission merely to propagandize?

Last Friday, Antarctica set its coldest EVER March temperature

…somehow, in what we’re to believe is a linearly warming world on the brink of “overheating”, the world’s southernmost continent is currently the coldest its ever been for the time of year.

The Vostok Station clocked a bone-chilling -75.3C (-103.54F) on the morning of Friday, March 20, as spotted by @TempGlobal on Twitter:

New research first to relate Antarctic sea ice melt to weather change in tropics

by C. Rotter, March 16, 2020 in WUWT


Diminishing sea ice translates to warmer ocean, more rain, and stronger trade winds.
University of California – San Diego

Arctic and Antarctic ice loss will account for about one-fifth of the warming that is projected to happen in the tropics, according to a new study led by Mark England, a polar climate scientist at Scripps Institution of Oceanography at the University of California San Diego, and Lorenzo Polvani, the Maurice Ewing and J. Lamar Worzel Professor of Geophysics at Columbia Engineering, England’s doctoral supervisor.

While there is a growing body of research showing how the loss of Arctic sea ice affects other parts of the planet, this study is the first to also consider the long-range effect of Antarctic sea ice melt, the research team said.

“We think this is a game-changer as it shows that ice loss at both poles is crucial to understanding future tropical climate change,” England said of the study funded by NASA and the National Science Foundation. “Our study will open a hitherto unexplored direction and motivate the science community to study the large effects that Antarctic sea ice loss will have on the climate system.”

Les glaces terrestres, la cryosphère (1/3)

by J.C. Maurin, 13 mars 2020 in ScienceClimatEnergie


On désigne par cryosphère l’ensemble des glaces terrestres. Son évolution, lors des dernières décennies, est souvent présentée comme préoccupante: il en résulterait une forte hausse des niveaux marins et un changement d’albédo et donc du bilan énergétique de la Terre. Cette première partie de l’article présentera quelques ordres de grandeurs pour les glaces terrestres.
On utilisera principalement les données du chapitre 4 du rapport AR5 WG1 (5th Assessment Report, Working Group 1) qui a été publié en 2013 par l’organisme intergouvernemental GIEC.

 

 

 

 

4. Conclusions

  • La cryosphère c’est en premier lieu les zones proches du pôle Sud : banquises et glaciers ne représentent ensemble que 0,7% du volume de la cryosphère alors que la seule partie Est de l’Antarctique, bien moins connue, représente plus de 75% de la cryosphère, soit 107 fois plus.
  • La simple correction du volume de glace en Antarctique, entre les rapports du GIEC AR4 (2007) et AR5 (2013), est 4 fois plus grande que le volume (Banquises + Glaciers).
  • Les variations actuelles de la cryosphère restent négligeables si on les compare à celles du passé : l’ensemble des glaces terrestres, il y a 20 millénaires, devait avoir un volume au moins double du volume actuel. En effet, la fonte des glaces (entre -18 ka et -8 ka) fait monter le niveau des océans de ≈ 120 m  contre 66 m SLE (Sea Level Equivalent à la Figure 1).

La deuxième partie de l’article (2/3) commentera les choix rédactionnels du GIEC pour le chapitre 4 de l’AR5 et donnera des ordres de grandeurs complémentaires pour les banquises et les glaciers.

La péninsule Antarctique se porte bien

by P. Berth, 28 février 2020 in ScienceClimatEnergie


Selon un récent article du Guardian, des scientifiques ont mesuré pour la première fois la température de 20,75°C le 9 février 2020 sur l’île Seymour, une île située au large de la péninsule Antarctique. Cette île comporte la station de mesure Marambio où les relevés ont été réalisés. Bien entendu, cette nouvelle a été reprise par les médias, Greta Thunberg en tête. Cependant, en analysant objectivement la situation vous pourrez constater qu’il n’y a pas lieu de s’alarmer.

1. Localisation de l’île Seymour et température moyenne annuelle

L’île Seymour est située au large de la péninsule Antarctique (Figure 1), la région la plus au nord du continent Antarctique et, quasiment, la seule partie d’Antarctique s’étendant au-delà du cercle polaire.

3. Conclusions

– Pour comprendre ce qu’il se passe dans un jeu de données de température il ne faut pas considérer une seule mesure comme le fait l’article du Guardian; il ne faut pas non plus considérer une seule station de mesure.

– Si l’on désire faire passer des droites parmi les données de température, les plus longues séries disponibles sont celles de la station Orcadas (depuis 1902), qui est quand même assez éloignée de la péninsule Antarctique. On constate alors un réchauffement d’environ + 2°C en 110 ans (la courbe de tendance coupe –5°C en 1900 et –3°C en 2010). Cependant, en considérant des courbes polynomiales dont le coefficient de détermination est meilleur on constate que les températures moyennes chutent depuis les années 2000, comme dans toutes les stations de la péninsule Antarctique présentées dans cet article.

– Les phénomènes naturels suivent rarement des droites. Ils sont généralement cycliques, avec des périodes et amplitudes très variables. Il est donc permis de conclure que la péninsule Antarctique ne se réchauffe pas depuis 25 ans. Ceci est confirmé par d’autres analyses (voir ici et ici) et il est dommage qu’une fois de plus les médias ne fassent pas plus preuve de rigueur et se permettent des raccourcis donnant une information inexacte à 100%. En sont-ils seulement conscients ?

Unexpected ice

by N. Vizcarra, February 2020 in EarthData/NASA


Paul Holland, a climate modeler with the British Antarctic Survey, has spent the last ten years studying Antarctica’s sea ice and the Southern Ocean. Lately, he has been scrutinizing the seasons of Antarctica and how fast the ice comes and goes. Holland thinks these seasons may be a key to a conundrum: If Earth’s temperatures are getting warmer and sea ice in the Arctic has been shrinking fast, why then is sea ice in the Antarctic slowly increasing?

Spring surprise

Holland used data from NASA’s National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) to calculate the ice concentration rate of growth for each single day, which he called intensification; and the total ice area rate of growth, which he called expansion. “I did that for all thirty years of data and plotted the trends,” he said. Holland’s plots showed that the different regions in the Southern Ocean contributed to the overall increase, but they had very diverse trends in sea ice growth. This suggested that geography and different wind patterns played a role. So to gain more insight Holland looked at seasonal wind trends for the different regions.

Holland found that winds were spreading sea ice out in some regions and compressing or keeping it intact in others and that these effects began in the spring. It contradicted a previous study in which, using ice drift data, Holland and Ron Kwok from the NASA’s Jet Propulsion Laboratory (JPL) found that increasing northward winds during the autumn caused the variations.

“I always thought, and as far as I can tell everyone else thought, that the biggest changes must be in autumn,” Holland said. “But the big result for me now is we need to look at spring. The trend is bigger in the autumn, but it seems to be created in spring.”

“Paul has created two more sea ice metrics that we can use to assess how Antarctic sea ice is responding,” said researcher Sharon Stammerjohn, referring to the measures of intensification and expansion. The new metrics help assess how the system is responding as opposed to simply monitoring the state of the system. “Say your temperature is at 99.2 degrees Fahrenheit,” Stammerjohn said. “You don’t have any insight to that temperature unless you take it again an hour later and you see that it changed to 101 degrees. Then you can say, okay, my system is responding to something.”

Is “All-Time Antarctic 20.75C Record High Temperature” Just A Sensational Hoax? Station Data Show Only 16C

by P. Gosselin, February 17, 2020 in NoTricksZone


In Germany there have been rumors that the alleged Antarctic Seymour Island “all-time Antarctic record high” of 20.75°C set on February 9th is a hoax – originating by the AFP news agency and then spread by The Guardian.

The alleged 20.75°C was supposedly logged by Brazilian scientists and was supposedly almost a full degree higher than the previous record of 19.8C, taken on Signy Island in January 1982, The Guardian blared with much alarm, citing its own rush job chart.

Currently the WMO is seeking to obtain the actual temperature data for Seymour Island, part of a chain of islands off the Antarctic peninsula.

WMO cites media as source!

The WMO website itself is citing the media as its source, writing: “Media reports say that researchers logged a temperature of 20.75°C. Mr Cerveny cautioned that it is premature to say that Antarctica has exceeded 20°C for the first time.”

Thermometer data show only 16°C!

According to German Facebook site Klima.Wissen here and its readers, the “all-time record high reading” of 20.75°C appears to have its origins from the AFP news agency. It was then picked up by the always climate sensational The Guardian. But now the whole story is beginning to appear as just big sensational hoax.

First, WetterOnline.de here shows that the high temperature on February 9th at the Seymour Island station (Base Murambio) was merely 16°C!

Greta’s, The Guardian’s Latest Panic Attack Over Antarctica Record Ignores Cooling Trends Of Recent Decades

by P. Gosselin, February 15, 2020 in NoTricksZone


In her latest panic attack, teenage Swedish climate activist Greta Thunberg – citing the Guardian –  once again appeared to be proclaiming the end of the world was a step closer when she tweeted Antarctica has set a new record high temperature:

 

Two new warm records

According to the Guardian, “The 20.75C logged by Brazilian scientists at Seymour Island on 9 February was almost a full degree higher than the previous record of 19.8C, taken on Signy Island in January 1982.”

That reading, the Guardian reports, follows the February 6 record of 18.3C recorded at the Argentinian research station, Esperanza measured.

As is the case with most alarmists, every warm single datapoint anomaly gets uncritically accepted with open arms as solid evidence of man-made global warming while cold trends get dismissed or downgraded as “natural variability”.

Seymour Island has been cooling for over a quarter century

So we have two recent warm records set at and near the Antarctic peninsula over the past week or so and that means the region there is heating up, alarmists like Greta and the Guardian want us to believe. But what are the real TRENDS there? Do the 2 recent warm records mean the region is heating up.

Looking at official data from NASA, it turns out that warming isn’t true. And because climate is always changing, the temperature in the region in question has also not remained completely steady. The only possibility left? COOLING.

OFFICIAL DATA REVEALS JANUARY 2020’S ANTARCTIC SEA ICE EXTENT TRACKED 1979-1990 AVERAGE

by Cap Allon, February 10, 2020 in Electroverse


According to official government data from the National Snow & Ice Data Center (NSIDC), Antarctic Sea Ice Extent is currently tracking the 1979-1990 average:

In addition, Jan 2020’s extent exceeded that of 2019, 2018, 2017, 2016, 2011, 2007, 2006, 2005, 2000, 1997, 1993, 1992, 1988, 1985, 1984, 1981, and 1980.

 

NO CORRELATION BETWEEN CO2 AND SEA ICE EXTENT

Since 1979 — the year sea ice satellite measurements began — CO2 readings taken at the Mauna Loa Observatory in Hawaii have been on an unnaturally linear rise. While, during the same period, Antarctic Sea Ice Extent has been “extremely variable” with “the yearly minimum hitting both record highs and lows” — NOAA (climate.gov)

Media’s Horribly Dishonest Antarctica Propaganda

by Jim Steele, February 9, 2020 in WUWT


The current context for the Antarctica Peninsula is that for over a decade it has experienced cooling temperatures driven by natural variability. In fact, glaciers in Esperanza’s region have also expanded. Esperanza’s record temperature simply happened due to foehn winds despite a cooling trend. Unfortunately, the media would rather scare the public to promote a climate crisis, than honestly educate them about the causes of natural climate variability.

Bloomberg It’s T-Shirt Weather in Antarctica as Temperature Breaks Record

by L.M. Lombrana, February 8, 2020
in NotaLotofPeopleKnowThat/Bloomberg


When one day’s weather is climate!
Paul Homewood

(Bloomberg) — The temperature at one research base in Antarctica reached a record-breaking 18.3 degrees Celsius (65 Fahrenheit) on Thursday, almost a full degree above the previous high set five years ago.

Argentine scientists on the Esperanza base who confirmed the reading said that wasn’t the only record broken this week. The nation’s Marambio site registered the highest temperature for the month of February since 1971. Thermometers there hit 14.1 Celsius, above the previous February 2013 reading of 13.8 Celsius.

The reports are shocking, but not surprising, said Frida Bengtsson, who is leading a expedition to the Antarctic for the environmental group Greenpeace.

Thwaites Glacier: Why Did The BBC Fail To Mention The Volcanoes Underneath?

by D. Whitehouse, January 29, 2020 in GWPF


Scientists have known for years that subglacial volcanoes and other geothermal “hotspots” are contributing to the melting of the Thwaites Glacier. Why did the BBC fail to mention these facts in its recent report?

 

The International Thwaites Glacier Collaboration is performing some magnificent science, conducting the most ambitious fieldwork ever undertaken at the tip of what is one of the most significant glaciers on Earth. Its melting already contributes 4% of global sea level rise and there are fears that it could become unstable and contribute many metres to global sea level.

The reason for its vulnerability lies in its geology. While most of the glacier is on ground and making its way into the West Antarctic seas, Thwaites lip floats on water allowing warm water to weaken and melt it from beneath. Being one of the most difficult places in the world to reach the scientific collaboration planned for years to transport many tonnes of equipment to the glaciers front. Two weeks ago they announced they had carried out the first warm water borehole through the ice at the point where it lifts off the land and starts to be suspended by the ocean.
