Officials who manage Glacier National Park are swapping out signs warning visitors that climate change would cause the park’s glaciers to disappear by 2020.
The U.S. Geological Survey told the park in 2017 that the complete melting off of the glaciers was no longer expected, park spokeswoman Gina Kurzmen told CNN.
Forecast models over the years show the glaciers were no longer at risk of disappearing by that date, she noted.
Placards at the St. Mary’s Visitor Center, located in Montana’s mountain ranges, were reportedly changed in 2019. The park is waiting for budget authorization to update the park’s full set of signs, Kurzman noted.
The signs will be changed to say: “When they will completely disappear depends on how and when we act. One thing is consistent: the glaciers in the park are shrinking.”

USGS noted in a report to the Daily Caller News Foundation in 2019 that recent harsh winters had significantly changed forecasts from years past.
“Glacier retreat in Glacier National Park speeds up and slows down with fluctuations in the local climate,” a representative with the USGS told the DCNF at the time. The agency is responsible for managing the park.
“Subsequently, larger than average snowfall over several winters slowed down that retreat rate and the 2020 date used in the NPS display does not apply anymore,” the representative said.

As we step into a new decade, here’s a look at the climate drama that just ended.
The 2010s were dominated by the failure of doomsday prophecies, the adoption of a fantasy climate agreement, unexpected weather trends, and the beginning of the climate emergency cult movement that reminded many of the overpopulation hype of the 1970s and 1980s.
Al Gore Prophecies
Al Gore’s legacy of lies continued to spill into the second decade of this century. Contrary to his predictions in the famous climate documentary An Inconvenient Truth, polar bear populations increased, the Arctic and Antarctic remained relatively unaffected, and no major coastal economy was threatened by rising sea levels.
Gore would have had nightmares when the Canadian authorities in 2019 pondered culling polar bears because of their excess numbers caused trouble for residents in Nunavut.

Nolte: Department of Defense Predicted Climate Change Would Destroy Us by 2020
by JOHN NOLTE 3 Jan 2020
Back in 2004, the Department of Defense released a report assuring the world Climate Change would destroy all of us by the year 2020.
Well, welcome to the year 2020! And welcome to yet another fake doomsday prediction number 42 from our renowned climate experts!
Yep, our so-called “climate experts” are now 0-42 with their doomsday predictions, and this latest one is a doozy.

• Depuis plus de 40 ans que des mesures de température sont effectuées par satellite, la basse et la moyenne troposphère se réchauffent bel et bien. Mais sans aucune accélération visible, et ce à des vitesses de l’ordre de +0.13°C/décade et +0.09°C/décade. La vitesse de réchauffement décroit donc avec l’altitude.
• La zone correspondant à la tropopause (vers 10 km d’altitude) ne se réchauffe pas, contrairement à ce que les modèles informatiques prédisent (pour plus de détails voir les articles de J. Christy). Peut-on alors continuer à utiliser ces modèles pour prédire la température de certaines couches atmosphériques dans le futur? Notons ici que les observations satellitaires sont confirmées par des observations réalisées in situ avec des ballons-sondes.
• La basse stratosphère se refroidit actuellement à la vitesse d’environ –0.29°C par décade, et l’analyse de corrélation menée par Varotsos et Efstathiou nous suggère que le comportement de la stratosphère n’est pas simplement lié à celui de la troposphère, les choses étant plus complexes.
• Les modèles climatiques actuels, basés sur l’hypothèse d’un l’effet de serre radiatif causé essentiellement par du CO2 atmosphérique, sont donc à revoir. Le CO2 (naturel ou d’origine anthropique) pourrait donc n’avoir qu’un rôle mineur et imperceptible sur la température de la troposphère.
En conclusion générale, nous devons toujours garder à l’esprit que le système climatique est très complexe car il est composé de cinq sous-systèmes (atmosphère, cryosphère, hydrosphère, biosphère et lithosphère) et que ces 5 sous-systèmes interagissent les uns avec les autres dans l’espace et le temps avec des processus principalement non linéaires (Lovejoy et Varotsos, 2016) et se comportent de manière chaotique (voir ici). Par conséquent, la modification d’un seul paramètre dans l’un des sous-systèmes (par exemple, la température de la basse troposphère) ne permet pas de prévoir un changement climatique à long terme, car tous les autres paramètres de l’atmosphère mais aussi ceux des autres sous-systèmes (connus et mesurables, ou non) ne sont pas nécessairement connus et stables. En plus de tout cela plusieurs facteurs externes, imparfaitement connus, peuvent influencer chacun des sous-systèmes, comme les rayonnements cosmiques ou les variations du champ magnétique solaire.

People sometimes ask me why I don’t believe the endless climate/energy use predictions of impending doom and gloom for the year 2050 or 2100. The reason is, neither the climate models nor the energy use models are worth a bucket of warm spit for such predictions. Folks concentrate a lot on the obvious problems with the climate models. But the energy models are just as bad, and the climate models totally depend on the energy models for estimating future emissions. However, consider the following US Energy Information Agency (EIA) predictions of energy use from 2010, quoted from here (emphasis mine):
The only thing that seems clear about all of those questions is that the answer is not “CO2”. Here’s another look at Greenland, this time with CO2 overlaid on the temperature:
by Roy Spencer, October 25, 2019 in GlobalWarming
The UN IPCC scientists who write the reports which guide international energy policy on fossil fuel use operate under the assumption that the climate system has a preferred, natural and constant average state which is only deviated from through the meddling of humans. They construct their climate models so that the models do not produce any warming or cooling unless they are forced to through increasing anthropogenic greenhouse gases, aerosols, or volcanic eruptions.
This imposed behavior of their “control runs” is admittedly necessary because various physical processes in the models are not known well enough from observations and first principles, and so the models must be tinkered with until they produce what might be considered to be the “null hypothesis” behavior, which in their worldview means no long-term warming or cooling.
What I’d like to discuss here is NOT whether there are other ‘external’ forcing agents of climate change, such as the sun. That is a valuable discussion, but not what I’m going to address. I’d like to address the question of whether there really is an average state that the climate system is constantly re-adjusting itself toward, even if it is constantly nudged in different directions by the sun.

1. Un nouveau paradigme : les systèmes chaotiques
« Depuis les premiers balbutiements de la Physique, le désordre apparent qui règne dans l’atmosphère, dans la mer turbulente, dans les fluctuations de populations biologiques, les oscillations du cœur et du cerveau ont été longtemps ignorées ».
« Il a fallu attendre le début des années soixante-dix, pour que quelques scientifiques américains commencent à déchiffrer le désordre, il s’agissait surtout de mathématiciens, médecins, biologistes, physiciens, chimistes cherchant tous des connections entre diverses irrégularités observées. Le syndrome de la mort subite fut expliqué, les proliférations puis disparitions d’insectes furent comprises et modélisées, et de nouvelles méthodes d’analyse de cours boursiers virent le jour, après que les traders aient dû se rendre à l’évidence que les méthodes statistiques conventionnelles n’étaient pas adaptées. Ces découvertes furent ensuite transposées à l’étude du monde naturel : la forme des nuages, les trajectoires de la foudre, la constitution de galaxies. La science du chaos (« dynamical systems » pour les anglo-saxons) était née et allait connaître un développement considérable au fil des années ».

Without the Earth’s greenhouse gases (GHG) in the atmosphere, the planet would be on average a frigid -18°C.
But because of the preindustrial 280 ppmv CO2 and other GHGs in our atmosphere, the average temperature of the Earth thankfully moves up by 33°C to +15°C (see chart below), based on the Stefan Boltzmann Law.
And because CO2 has since risen to about 410 ppmv today, the global temperature supposedly should now be about another 1°C warmer (assuming positive feedbacks) bringing the average earth’s temperature to 16°C.
And once the preindustrial level of CO2 gets doubled to 560 ppm, later near the end of this century, global warming alarmists insist the Earth’s temperature will be near 18°C, see chart above.
So we are now supposed to be at 16°C today and warming rapidly. But what is the globe’s real average temperature today? 15.8C? 16.0C? 16.5°C?
Answer: astonishingly the official institutes tell us it is only 14.7°C!
For example, data from the World Meteorological Organization (WMO) shows us the global absolute temperatures for the previous 5 years:
Image: www.klimamanifest.ch, data source: WMO in Geneva.
As the image above shows, the global absolute temperature last year was just 14.68°C.
This is 0.32°C COOLER than the 15°C we are supposed to have with 280 ppmv, and a whopping 1.32°C cooler than the 16°C it is supposed to be with the 410 ppmv CO2 we have in our atmosphere today.
So why are we missing over 1.3°C of heat? Why is there this huge discrepancy between scientists?

Si le sujet « vérité et connaissance scientifique » est un pilier de la philosophie classique et de l’épistémologie contemporaine, il se pourrait bien que, dans une ère de post-vérité, ce thème soit progressivement remplacé par celui de la chasse aux « fausses informations ». Pour le dire autrement, ce qui compte, ce n’est plus la quête d’un sens métaphysique ou une recherche de cohérence logique, mais qu’un énoncé tienne le plus longtemps possible à la Une de l’actualité avant d’être remis en cause.
En affirmant ceci notre objectif n’est pas de donner un blanc seing au relativisme ou d’abandonner la méthode scientifique, bien au contraire. Il s’agit de réfléchir sur la possibilité de redonner à celle-ci sa superbe ; d’autant plus qu’elle n’est plus simplement une affaire de scientifiques : les médias, les politiques, les ONG et l’opinion s’emparent immédiatement de la moindre expérience rendue publique et se trouvent engagés de manière quasi instantanée dans le processus de « vérification » qui passe d’abord souvent par l’acceptation. Ce qui montre la nécessité d’éduquer l’opinion pour lui apprendre à détecter les différentes typologies d’erreurs scientifiques. Voici donc une petite grille de lecture que nous avons établie en classant cinq grandes typologies d’informations scientifiques qui se sont révélées fausses…

Canadians already suspicious of Prime Minister Justin Trudeau’s carbon tax will likely be even more suspicious given a report by Ottawa-based Blacklock’s Reporter that Environment Canada omitted a century’s worth of observed weather data in developing its computer models on the impacts of climate change.
The scrapping of all observed weather data from 1850 to 1949 was necessary, a spokesman for Environment Canada told Blacklock’s Reporter, after researchers concluded that historically, there weren’t enough weather stations to create a reliable data set for that 100-year period.
“The historical data is not observed historical data,” the spokesman said. “It is modeled historical data … 24 models from historical simulations spanning 1950 to 2005 were used.”
These computer simulations are part of the federal government’s ClimateData.ca website launched by Environment Minister Catherine McKenna on Aug. 15.
She described it as “an important next step in giving our decision-makers even greater access to important climate data for long-term planning. The more each of us uses this type of information, the more it will help.”
Blacklock’s Reporter, which describes itself as “the only reporter-owned and operated newsroom in Ottawa” focusing on intensive reporting of government documents, notes that in many cases the observed temperatures scrapped by Environment Canada in creating its computer models were higher in the past than today.
For example, Vancouver had a higher record temperature in 1910 (30.6C) [87.08F] than in 2017 (29.5C) [85.1F].

In a recent interview with the online Berliner Zeitung (BZ) here, economist Björn Lomborg said that 16-year old Greta Thunberg’s demands “will put people in danger”.
Greta, the Swedish teenage activist is calling for radical cuts in CO2 emissions – on a scale that would have profound impacts on the world’s market system. Moreover, Lomborg calls the demands immoral. Lomborg says it would be far wiser to invest money in bringing the world’s poor out of grinding poverty rather than to try to mitigate climate change.
Fear based on 30 years of lies and exaggerations
“Rich countries that tell poor countries not to use fossil energy for the benefit of the environment are acting immorally,” Lomborg told the BZ.
Lomborg also sharply criticized Thunberg, telling BILD news daily: “Greta Thunberg fears the end of the world due to climate change. This fear is the result of three decades of alarmist rhetoric based on exaggerations and lies.”
€43 billion for 0.00001°C of temperature reduction yearly
Lomborg also called Germany’s “Energiewende” – transition to green energies – “the best example of a failed climate policy” which has proven to be “incredibly costly and ineffective.”
“Global warming will be reduced by 0.001 degrees at most by 2100 for 43 billion euros a year,” he told the BZ. Lomborg blames the adults for panicking Ms Thunberg and using her “to push through an agenda that costs trillions but brings almost no benefits.”
Rather, for the trillions we will likely get us far graver problems. What a deal.

Rep. Alexandria Ocasio-Cortez recently suggested Miami would disappear in “a few years” due to climate change. The United Nations is convening a “Climate Action Summit” next week. And climate activist Greta Thunberg is on Capitol Hill this week telling lawmakers they must act soon.
But while data from NASA and other top research agencies confirms global temperatures are indeed rising, a newly compiled retrospective indicates the doomsday rhetoric is perhaps more overheated.
The conservative-leaning Competitive Enterprise Institute has put together a lengthy compilation of apocalyptic predictions dating back decades that did not come to pass, timed as Democratic presidential candidates and climate activists refocus attention on the issue.
The dire predictions, often repeated in the media, warned of a variety of impending disasters – famine, drought, an ice age, and even disappearing nations – if the world failed to act on climate change.
An Associated Press headline from 1989 read “Rising seas could obliterate nations: U.N. officials.” The article detailed a U.N. environmental official warning that entire nations would be eliminated if the world failed to reverse warming by 2000.
Then there were the fears that the world would experience a never-ending “cooling trend in the Northern Hemisphere.” That claim came from an “international team of specialists” cited by The New York Times in 1978.

German climate scientist Professor Werner Kirstein was interviewed by alternative media outlet NuoViso, and since the video was released early this month on Youtube, it has been viewed over 130,000, times.
Politics commissioning reports for money
In the interview Professor Kirstein tells moderator Robert Stein that CO2 emissions have no effect on the climate and that “politicians commission climate scientists to produce expert reports for money.”
“Public is being deceived”
Prof. Kirstein talks about the “conscious deception” of the public and how all research projects and publications by “climate scientists” only have the goal of confirming “man-made climate change” and that different scientific views are not welcome.
According to Kirstein, the public is being deceived with the false information and that the aim of politics is to find a way to collect further taxes and to collect levies.
“We currently see this with the climate tax, which is to be introduced soon,” Kirstein says.

There is no debate as to whether or not atmospheric carbon dioxide, or CO2, is a so-called greenhouse gas. When present in the atmosphere, this one-carbon and two-oxygen molecule indeed has the capacity to absorb infrared radiation and warm the planet. There is also no debate as to whether or not the concentration of atmospheric CO2 is rising; over the past two centuries it has increased from a meager 0.028% of the atmosphere by volume to a still-meager 0.041% today. Furthermore, there is no argument that global temperatures are warmer today than they were 50, 100 or even 200 years ago. However, there is much debate on whether or not the modern increase in atmospheric CO2 has caused, or is presently causing, dangerous global warming, warming so severe that it is threatening life all across the planet.
But how accurate is this narrative?
In answering this question, one need only examine the historic temperature and CO2 records illustrated in Figure 1 more critically. Certainly, these two variables experience a fairly high degree of correlation over the time period shown. However, it doesn’t take a Ph.D. scientist to recognize and understand the fact that correlation among two variables does not prove causation. Every textbook on statistics teaches as much, and they also teach that a hypothesis of causation among two variables can be rejected if there is no statistically significant correlation between them, or if the correlation fails to be maintained in a consistent and expected manner across time.
By applying such principles to the case being considered here, it can confidently be argued that if carbon dioxide is indeed the all-important control knob of temperature that climate alarmists claim it to be, then changes in atmospheric CO2 should always precede changes in temperature. And, because CO2 is a greenhouse gas, to prove causation those changes must always be such that a rise in CO2 induces a corresponding rise in temperature, whereas a decline in CO2 must always induce a corresponding drop in temperature. Consistent observations to the contrary, if present in the historic record, would therefore serve to invalidate a causation claim, as well as demonstrate that atmospheric CO2 is nothing more than a bit player among the many factors that drive climate change.

The US state of Alaska, part of which lies inside the Arctic Circle, is sweltering under a heatwave, with record temperatures recorded in several areas, including its largest city.
Temperatures reached 90F (32C) in Anchorage on Thursday, shattering the city’s previous record of 85F.
The report clearly implied global warming as the cause, with several references to climate change links throughout the article.
As I pointed out at the time, the all-time record temperature for Alaska was set as long ago as 1915, when an incredible 100F was measured at Fort Yukon.
This story follows the usual BBC recipe for Arctic heatwaves:
- Record temperatures = global warming
- Hot weather is unprecedented in the Arctic. Most people would believe that temperatures of 90F simply never used to occur in the Arctic, it just sounds so unimaginable.
Unfortunately for the BBC, it turns out that the Anchorage temperature is not even a record!
I have now had time to check through the NOAA data files, and have discovered that back in June 1931, the temperature actually reached 92C at Anchorage:

This essay explains in simple terms why so many people still believe that polar bears are in peril when nothing could be further from the truth; it is an essential lesson that shatters the basis of the shameful indoctrination of young school children and undermines the baseless claims of activist protestors.
It was written and translated into French for a special climate change feature issue (July) of the monthly French magazine Valeurs Actuelles (reviewed here) and reprinted by the French hunting magazine Chasses Internationales.
It has also been translated into German for a dedicated climate change issue (11 July) of the Swiss weekly magazine Die Weltwoche.

It’s getting worse.
About 5 years ago, I wrote two blog posts on climate scientists’ pre-traumatic stress syndrome:
Mother Jones has a new article on the same topic: It’s the end of the world as they know it: The distinct burden of being a climate scientist.
The following scientists were interviewed: Kim Cobb, Priya Shukla, Peter Kalmus, Sarah Myhre, Jacquelyn Gill, Katharine Wilkinson, Eric Holthaus, David Grinspoon, Ken Caldeira.
Lots of ‘trauma,’ read the article to get a flavor. This sentence pretty much sums things up:
“There’s deep grief and anxiety for what’s being lost, followed by rage at continued political inaction, and finally hope that we can indeed solve this challenge. There are definitely tears and trembling voices.”
End of civilization?

National Oceanic and Atmospheric Administration reported the month of May was the second wettest and temperatures were in the bottom-third for its 125-year US history.
The 2010 publication titled, ‘A Global Overview Of Drought and Heat-Induced Tree Mortality Reveals Emerging Climate Change Risks for Forests’, was accepted by the Obama administration as scientific evidence that climate change had made the Earth:
“…increasingly vulnerable to higher background tree mortality rates and die-off in response to future warming and drought, even in environments that are not normally considered water-limited.”
But NOAA just reported that May US precipitation totaled an average of 4.41 inches, 1.50 inches above average, and ranked second wettest in the 125-year period of record for May as well as second wettest for all months since January 1895.
The only wetter month in US history was May 2015 with 4.44 inches of precipitation.
The 37.68 inches of precipitation across the contiguous U.S. from June 2018 to May 2019 shattered the previous 1982-83 12-month period by 1.48 inches.
Near-record to record precipitation was observed from the West Coast through the central Plains and into the Great Lakes and parts of the Northeast.
As a result, severe May flooding was observed along the Arkansas, Missouri, and Mississippi rivers. Vicksburg, MS, reported ongoing flooding since mid-February.

Straight from the horse’s mouth: all polar bear females tagged by researchers around Churchill in Western Hudson Bay last year were still on the ice as of 25 June. With plenty of ice still remaining over the bay, spring breakup will be no earlier this year than it has been since 1999. Contrary to predictions of ever-declining ice cover, the lack of a trend in sea ice breakup dates for Western Hudson Bay is now twenty years long (a hiatus, if you will) and yet these bears are repeatedly claimed to have been seriously harmed in recent years by a loss of sea ice.

Consider the following: we do not know all the variables that control our climate, but we are quite sure they are likely in the hundreds.
Just take a quick look at ten obviously important factors for which we have limited understanding:
1- Changes in seasonal solar irradiation;
2- Energy flows between ocean and atmosphere;
3- Energy flow between air and land;
4- The balance between Earth’s water, water vapor, and ice;
5- The impacts of clouds;
6- Understanding the planet’s ice;
7- Mass changes between ice sheets, sea level and glaciers;
8- The ability to factor in hurricanes and tornadoes;
9- The impact of vegetation on temperature;
10- Tectonic movement on ocean bottoms.
Yet, today’s modelers believe they can tell you the planet’s climate decades or even a century in the future and want you to manage your economy accordingly.
Dr. Willie Soon of the Harvard-Smithsonian astrophysics laboratory once calculated that if we could know all the variables affecting climate and plugged them into the world’s largest computer, it would take 40 years for the computer to reach an answer.

May normally is a month that sees rapid snow melt in Alps. But this year May was an unusually cold month across Central Europe and parts of the Alps saw heavy snow accumulation.
A week ago, on May 25, BR public broadcasting reported here how May snow levels at Germany’s tallest peak, Zugspitze, reached a 20-year high at just over 6 meters of depth. The article wrote that experts thought the depth would not rise further.
But that turned out to be wrong.
Highest level since February, 1981
Four days later, on May 29, another 35 cm were added and pushed the depth to 6.40 meters, according to wetteronline.ch here. the website wrote: “Zugspitze: Never so much snow since 1981.” The website added that the snow depth there was “higher than it has been since February 1981.”

A leading climatologist has said that the computer simulations that are used to predict global warming are failing on a key measure of the climate today and cannot be trusted.
Speaking to a meeting in the Palace of Westminster in London, Professor John Christy of the University of Alabama in Huntsville told MPs and peers that almost all climate models have predicted rapid warming at high altitudes in the tropics:
A paper outlining Dr. Christy’s key findings is published today by the Global Warming Policy Foundation.
