ALL-TIME RECORD LOW TEMPERATURES SET ACROSS MONTANA + ONE TIED FROM 1898

by Cap Allon, July 23, 2019 in Electroverse


With the few days of ‘eastern heat’ taking all the headlines, the anomalous and long-lasting cold infecting vast swathes of North America is again being swept under the sustainably-sourced non-synthetic-petroleum-derived-fiber carpet. Record cold hit Montana over the weekend with several cities and towns setting new all-time record lows, but I’ll bet my diesel-guzzling L200 you never heard about it.

I’ve listed a few of the new record lows below:

  • Utica set a new record low of -1.1C (30F) on Saturday July 20.
  • Kalispell’s 2.2C (36F) busted the previous record of 3.3C (38F) set in 1996 (solar minimum of cycle 22).

CO2 Is So Powerful It Can Cause Global Warming To Pause For Decades

by Joanna Nova, July 24, 2019 in ClimateChangeDispatch


It’s all so obvious. If researchers start with models that don’t work, they can find anything they look for — even abject nonsense which is the complete opposite of what the models predicted.

Holy Simulation! Let’s take this reasoning and run with it  — in the unlikely event, we actually get relentless rising temperatures, that will imply that the climate sensitivity of CO2 is lower. Can’t see that press release coming…

Nature has sunk so low these days it’s competing with The Onion.

The big problem bugging believers was that global warming paused, which no model predicted, and which remains unexplained still, despite moving goalposts, searching in data that doesn’t exist, and using error bars 17 times larger than the signal.

The immutable problem is that energy shalt not be created nor destroyed, so The Pause still matters even years after it stopped pausing.

The empty space still shows the models don’t understand the climate — CO2 was supposed to be heating the world, all day, every day.

Quadrillions of Joules have to go somewhere, they can’t just vanish, but models don’t know where they went. If we can’t explain the pause, we can’t explain the cause, and the models can’t predict anything.

In studies like these, the broken model is not a bug, it’s a mandatory requirement — if these models actually worked, it wouldn’t be as easy to produce any and every conclusion that an unskeptical scientist could hope to “be surprised” by.

The true value of this study, if any, is in 100 years time when some psychology Ph.D. student will be able to complete an extra paragraph on the 6th-dimensional flexibility of human rationalization and confirmation bias.

Busted climate models can literally prove anything. The more busted they are, the better.

Developing nations latest decade of energy & emissions growth torpedoes alarmist global emissions control scam

by Larry Hamlin, July 23, 2019 in WUWT


The UN has been pursuing global emissions policy for decades that are intended to provide for the establishment of global government schemes allowing it to control world emissions.

No fewer than 24 United Nations Climate Change Conferences have been held at various global locations since 1995 under its Conference of the Parties (COP) legal framework.

COP 21 which occurred in November and December 2015 in Paris resulted in the creation of the Paris Agreement that supposedly established global agreement to reduce greenhouse gas emissions and limit future global temperatures that the UN based upon projections from climate models that grossly exaggerate the impact of greenhouse gases on world temperatures.

The UN IPCC acknowledged in its AR3 climate report in 2001 that it is not possible to develop computer models that are capable of predicting future global climate and yet the Paris Agreement based its emissions targets intended for the future using these flawed computer models.

Three additional UN climate conferences have occurred since the Paris Agreement with the last conference being in 2018 in Poland. No success has been achieved in these three conferences in devising specific commitments for emissions reductions targets for the world’s developing nations.

Additionally the U.S. under President Trump wisely withdrew from the Paris Agreement in June of 2017.

Global energy and emissions detailed information for 2018 is now available which includes data encompassing the latest decade of 2008 to 2018. The world energy consumption data from the report is summarized in the graph below.

This latest decade energy and emissions data clearly demonstrates that the developing nations completely dominate global energy and emissions. This includes both present levels as well as future growth. These results also show that the developed nations play a minority role in these measures both presently and in the future.

The results for the last decade show that global energy use grew by 18.5% during the last decade with 98.5% of that energy growth accounted for by the developing nations.

China Energy to expand ultra-low emission coal-fired power: executive

by Reuters, July 23, 2019 in WUWT


SANHE, China (Reuters) – China Energy Group, the country’s biggest power generator, will add more than 6 gigawatts (GW) of new ultra-low emission coal-fired capacity this year as it bids to meet growing electricity demand, a senior official with the firm said on Thursday.

The company also expected to build another 5 GW of low-emission capacity next year, Xiao Jianying, the head of the state-run firm’s coal-fired power department, told Reuters.

“China still has quite a big demand for electricity. The government now supports regions with poor wind and solar resources to use coal-fired power … it’s a more practical measure, as gas is still too expensive,” said Xiao.

China Energy operated coal-fired plants with a total capacity of 175 GW at the end of 2018, 77.4% of its total capacity and about 10% of the entire country’s capacity.

Xiao said the company would gradually shut down small and polluting coal-fired power units and replace them with efficient ones, noting that total capacity would continue to increase but at a slower rate of growth.

The firm is also planning to launch another carbon capture and storage (CCS) project in northwest China next year as part of its efforts to reduce the environmental impact of using coal, company officials said. It already runs a CCS plant at its coal-to-oil facility in Erdos in Inner Mongolia.

China, the world’s biggest greenhouse gas emitter, has vowed to control new coal production and new coal-fired power capacity as part of its commitments to curb pollution and tackle global warming. However, it has shown signs of relaxing restrictions in recent months amid an economic slowdown.

1980s Science: Ice Cores Show CO2 Naturally Rose 200 ppm (65 ppm/100 Years) During The Early Holocene

by K. Richard, July 22, 2019 in NoTricksZone


A few decades ago it was “consensus” science that CO2 levels had reached 400 ppm (and even up to 500 ppm) during the Early Holocene, with rising amplitudes of greater than 200 ppm and rates of 65 ppm in less than a century. Then the “consensus” opinion changed.

In 1982 it was still quite acceptable for Dr. Flohn, a climate scientist, to acknowledge that changes in CO2 concentration changes are significantly determined by temperature “rather independent of” fossil fuel emissions, but also that Holocene CO2 concentrations reached 350 to 400 ppm between 8,000 to 6,000 years ago (Flohn, 1982).

Why the discrepancy between “consensus” CO2 and historically recorded CO2?

Polish physicist Dr. Zbigniew Jaworowski (1997) was a fierce critic of the means by which ice core data have been collected to assign CO2 concentration values to past epochs.

His criticisms center around the post-1985 tendencies for fellow scientists to openly employ selection bias in making pre-determined decisions about what measurements are “right” and which ones are “wrong” – effectively rendering their results meaningless.

He cites Pearlman et al. (1986), for example. These authors collected 74 Antarctic ice core CO2 samples. Of those, 32 (43%) were rejected because they had values that were too high or too low to match with the agreed-upon pre-determination.

In what other branch of science is it acceptable to discard measured data we don’t agree with?

 

New York Heatwaves Like This Week’s Are The Norm

by P. Homewood, July 22, 2019 in NotaLotofPeopleKnowThat


Extremely hot weather has started to hit most of the United States, with temperatures set to peak over the weekend, meteorologists say.

The heatwave could affect about 200 million people in major cities like New York, Washington and Boston in the East Coast, and the Midwest region too.

In some places, temperatures could be close to or exceed 100F (38C). Parts of Canada are also being hit.

Experts link more frequent heatwaves in recent years to climate change.

The world experienced its hottest June on record this year, with an average temperature worldwide of 61.6F (16.4C), according to new data.

Earlier this month, the US state of Alaska, part of which lies inside the Arctic Circle, registered record high temperatures.

https://www.bbc.co.uk/news/world-us-canada-49049378

 

As I revealed last week, the Alaska claim was fake.

But what about this latest heatwave? Is it anything unusual?

Well not in New York, that’s for sure.

The temperature in Central Park never even got near 100F, peaking at 95F yesterday.

RUSSIA BREAKS MORE ALL-TIME LOW TEMPERATURE RECORDS, INCLUDING ONE FROM 1893

by Cap Allon, July 19, 2019 in Electroverse


On the back of Russia’s horde of new record low temperatures set on July 12, a bucket-load more were set over the following few days, busting records that had previously stood for well over 100 years.

The mercury across the majority of Europe has remained well-below average during the month of July as a string of Arctic blasts continue to delay the start of the continent’s summer. Large regions are seeing temperature departures of up to 20C below average, sending all-time cold records tumbling.

 …

And now Russia has 7 more daily records to add to the ever-expanding list (data courtesy of www.hmn.ru):

  • Sortavala recorded 3.8C (38.8F) — busting the previous record of 4.2C (39.6F) set in 1971.
  • Vytegra’s 0C (32F) beat the previous record of 1.5C (34.7F) from way back in 1893.
  • Vyborg observed 6.7C (44F) surpassing the 7C (44.6F) set in 1978 (solar minimum of cycle 20).
  • Roslavl’s 7C (44.6F) beat out the 7.9C (46.2F) from 1935 (solar minimum of cycle 15).
  • Cherepovets4.1C (39.4F) busted the 4.8C (40.6F) set in 1995 (solar minimum of cycle 22)
  • Rybinsk registered 7.2C (45F) smashing the previous record low of 9.9C (49.8F) from 1977 (solar minimum of cycle 20).

While Kostroma’s 5.7C (42.3F) beat 1948’s record of 6.9C (44.4F).

What’s really killing the Coral Reefs?

by Carly Cassella, July 20, 2019 in WUWT


Coral reefs are one of the most threatened ecosystems on our planet, and in the past two decades alone, half of the coral in Florida has died off completely. Global warming is known to be a deadly factor, but rising ocean temperatures are only part of the story.

Thirty years of research in the Looe Key Sanctuary Preservation Area (LKSPA) on the southern tip of the Florida Keys has now revealed the cost of a devastating threat to coral that rivals even climate change: direct human pollution.

For years, agricultural run-off and improperly treated sewage have flowed into Florida’s ocean waters from the northern Everglades, elevating the sanctuary’s nitrogen levels and lowering the reef’s temperature threshold for bleaching, researchers say.

As a result of this deadly combination, coral cover in the region has declined from nearly 33 percent in 1984 to less than 6 percent in 2008.

In their analysis, the authors found that three mass bleaching events that occurred during these years only happened after heavy rainfall and increased land-based runoffs. In other words, if we can reduce the amount of local pollution that makes its way into our oceans, we might be able to reduce the worst of the damage.

Geoscientists discover mechanisms controlling Greenland ice sheet collapse

by University of South Florida (USF Innovation), July 19, 2019 in ScienceDaily/Nature


 

Greenland’s more than 860,000 square miles are largely covered with ice and glaciers, and its melting fuels as much as one-third of the sea level rise in Florida. That’s why a team of University of South Florida geoscientists’ new discovery of one of the mechanisms that allows Greenland’s glaciers to collapse into the sea has special significance for the Sunshine State.

New radar technology allowed geoscientists to look at Greenland’s dynamic ice-ocean interface that drives sea level rise.

Earlier this spring, NASA scientists reported Jakobshavn Glacier, which has been Greenland’s fastest -thinning glacier for the last 20 years, was slowing in its movement toward the ocean in what appears to be a cyclical pattern of warming and cooling. But because Jakobshavn is still giving up more ice than it accumulates each year, its sheer size makes it an important factor in sea level rise, the NASA scientists maintain.

“Our study helps understand the calving process,” Dixon said. “We are the first to discover that mélange isn’t just some random pile of icebergs in front of the glacier. A mélange wedge can occasionally ‘hold the door’ and keep the glacier from calving.”

2019 Climate “Ship Of Fools” Runs Into 3-Meter Thick Ice… Baffin Inlets Mid Summer Ice Extent No Trend in 50 Years

by P. Gosselin, July 19, 2019 in NoTricksZone


Our German skeptic friend Snowfan here keeps us up to date on the latest ODEN “Ship of Fools” attempt to travel across an Arctic that is supposed to be ice-free by now.

The incentive to cross the Arctic passages in the summer is huge. Doing so would mean at least a week of fame with the media blaring out your name along with grossly hyped headlines of an Arctic ice meltdown due to global warming. One of these years, a ship might get lucky and manage to get through the Northwest Passage.

Also defying the models is the extent of ice cover for July 9 at the Baffin inlets Regent – Boothia. Over the last 50 years, there’s been little trend change:

Strong storms also play big role in Antarctic ice shelf collapse

by Oregon State University, July 18, 2019 in ScienceDaily


Warming temperatures and changes in ocean circulation and salinity are driving the breakup of ice sheets in Antarctica, but a new study suggests that intense storms may help push the system over the edge.

A research team led by U.S. and Korean scientists deployed three moorings with hydrophones attached seaward of the Nansen Ice Shelf in Antarctica’s Ross Sea in December of 2015, and were able to record hundreds of short-duration, broadband signals indicating the fracturing of the ice shelf.

The “icequakes” primarily took place between January and March of 2016, with the front of the ice sheet calving into two giant icebergs on April 7. The day the icebergs drifted away from the shelf coincided with the largest low-pressure storm system the region had recorded in the previous seven months, the researchers say.

Results of the study are being published this week in Frontiers in Earth Science.

La croissance du CO2 dans l’atmosphère est-elle exclusivement anthropique? (3/3)

by J.C. Maurin, 19 juillet 2019 in ScienceClimatEnergie


Effet Bombe et Modèles du GIEC

Les prévisions du climat sont générées par des modèles informatiques. Leurs concepteurs pensent pouvoir décrire l’état moyen de l’atmosphère en 2100, en prenant comme principale donnée d’entrée, le taux futur de CO2 qui constituerait donc le ‘bouton de commande’ du climat.

Il y a deux étages de modélisation : on commence par prévoir le taux de CO2 en 2100 avec des modèles sélectionnés par le GIEC (ces modèles « IRF » du GIEC sont l’objet de l’article).
Cette prévision constitue ensuite l’entrée du second étage, à savoir les modèles types « échanges radiatifs » ou « effet de serre » qui ne sont pas traités ici (mais on peut consulter ceci).
Le présent article ( qui est la suite de deux autres ici et ici) compare la réponse impulsionnelle théorique de ces modèles « IRF » avec la réponse impulsionnelle observée du 14CO2(effet Bombe).

Study: Pacific Islands Will Survive Climate Change

Pacific atolls can adapt to rising seas and extreme storms – new study

Low-lying Pacific islands in atoll archipelagos such as Tuvalu, Tokelau and Kiribati are likely to adapt to the effects of climate change rather than simply sink beneath the waves, a new study shows.

Tuvalu, Tokelau and Kiribati are widely considered under threat from rising seas and severe storms due to climate change with their residents becoming ‘climate refugees’.

Researchers from the University of Auckland’s School of Environment recreated a scale model of tiny Fatato Island on the southeast rim of Funafuti Atoll in Tuvalu to test the ability of the real island to withstand predicted climate affects.

The study simulated higher sea levels and storm-generated waves up to 4m in a 20m-long water chute or ‘flume’ to replicate real-world sea levels of 0.5m and 1m in a purpose built laboratory at the University of Plymouth in the United Kingdom.

The Response of Grape Plantlets to CO2 Enrichment

by Zhao et al., 2019 in BMCPlantBiology/CO2Science


Recognizing that increasing atmospheric CO2 concentrations promotes plant development and growth, Zhao et al. set out to investigate the effect of elevated CO2 on a key wine grape variety, Pinot Noir.

Their experiment was conducted in controlled climate chambers at the Fruit Tree Physiology and Biotechnology Laboratory, College of Horticulture, Gansu Agricultural University, China. Grape plantlets (Vitis vinifera, cv. Pinot Noir) were propagated and then cultured in a 2% sucrose solution at either ambient (380 ppm) or elevated (1,000 ppm) CO2 concentrations for a period of 25 days. At the end of the experiment the authors examined the impact of CO2 on various growth-related parameters, while also conducting transcriptomic and proteomic analyses.

Results indicated that elevated CO2 stimulated total plant dry weight, leaf area and plant height by 125%, 96% and 31%, respectively (see Figure 1). Photosynthetic parameters also revealed a CO2-induced stimulation and the various physiological changes were found to be related to differentially expressed genes and proteins among the plants growing in the two environments. Such findings suggest Pinot Noir may well be a “winner” (in terms of growth and development) among plants in the future if the air’s CO2 content continues to rise.

Figure 1. Visual display of the growth differences between grapes grown under ambient (380 ppm) or elevated (1,000 ppm) CO2 concentrations for 25 days. The average dry weight of the grapes growing under elevated CO2 was 125% greater than those growing under ambient CO2. Source: Zhao et al. (2019).

10 fallacies about Arctic sea ice & polar bear survival: teachers & parents take note

Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical misconceptions, fallacies, and disinformation abound regarding Arctic sea ice and polar bear survival. Ahead of Arctic Sea Ice Day (15 July), here are 10 fallacies that teachers and parents especially need to know about.

NO EXPERIMENTAL EVIDENCE FOR THE SIGNIFICANT ANTHROPOGENIC CLIMATE CHANGE

by J. Kauppinen and P. Malmi, July 13, 2019 in Physics.gen-ph


Abstract. In this paper we wil lprove that GCM-models used inI IPCC report AR5 fail to calculate the influences of the low cloud cover changes on the global temperature. That is why those models give a very small natural temperature change leaving a very large change for the contribution of the green house gases in the observed temperature. This is the reason why IPCC has to use a very large sensitivity to compensate a too small natural component. Further they have to leave out the strong negative feedback due to the clouds in order to magnify the sensitivity. In addition, this paper proves that the changes in the low cloud cover fraction practically control the global temperature.

1. Introduction

The climate sensitivity has an extremely large uncertainty in the scientific lit- erature. The smallest values estimated are very close to zero while the highest ones are even 9 degrees Celsius for a doubling of CO2. The majority of the papers are using theoretical general circulation models (GCM) for the estimation. These models give very big sensitivities with a very large uncertainty range. Typically sensitivity values are between 2–5 degrees. IPCC uses these papers to estimate the global temperature anomalies and the climate sensitivity. However, there are a lot of papers, where sensitivities lower than one degree are estimated without using GCM. The basic problem is still a missing experimental evidence of the cli- mate sensitivity. One of the authors (JK) worked as an expert reviewer of IPCC AR5 report. One of his comments concerned the missing experimental evidence for the very large sensitivity presented in the report [1]. As a response to the com- ment IPCC claims that an observational evidence exists for example in Technical Summary of the report. In this paper we will study the case carefully.

2. Low cloud cover controls practically the global temperature

Antarctica was warmer one thousand years ago — and life was OK

JoNova, July 11, 2019


Remember when polar amplification was the rage? So much for that theory

Antarctica is twice the size of the US or Australia. Buried 2 km deep under domes of snow, it holds 58 meters of global sea level to ransom. The IPCC have been predicting its demise-by-climate-change for a decade or two.

A new paper looks at 60 sites across Antarctica, considering everything from ice, lake and marine cores to peat and seal skins. They were particularly interested in the Medieval Warm Period, and researched back to 600AD.  During medieval times (1000-1200 AD) they estimate Antarctica as a whole was hotter than it is today.  Antarctica was even warmer still  — during the dark ages circa 700AD.

Credit to the paper authors: Sebastian Lüning, Mariusz Gałka, and Fritz Vahrenholt

Feast your eyes on the decidedly not unprecedented modern tiny spike:

The little jaggy down after 2000 AD is real. While there was rapid warming across Antarctica from 1950-2000, in the last twenty years, that warming has stalled. Just another 14 million square kilometers that the models didn’t predict.

We already knew the Medieval Warm Period was a global phenomenon, thanks to hundreds of proxies, and 6,000 boreholes. But this new paper is a great addition.

With an awesome dedication to detail, the team put all the big oceanic and other factors into one big graph. It is nice to see them side by side so we can see the connections between them.

Study: Clouds, Solar Cycles Play Major Role In Climate Change

by  G. Lloyd, July 15, 2010 in ClimateChangeDispatch


Sand deposits near the Gobi Desert in China may seem a strange place to look for evidence that cosmic rays can control how clouds are formed and the impact they have on Earth’s climate.

But Japanese scientists have measured the size of sand grains and the distance they traveled 780,000 years ago to add a new level of understanding to one of the questions that continue to baffle climate science: clouds.

The findings, published in Nature, point to big trends in natural variation of past and future climate that operate apart from greenhouse gas levels.

The study adds weight to a contentious theory by Danish researcher Henrik Svensmark, of the Danish National Space Institute in Copenhagen, which uses cosmic rays and clouds to question the sensitivity of climate to carbon dioxide in the atmosphere.

Red Sea Temperature Record Shows It Follows The AMO, Not CO2 … “Natural Climate Oscillations”

by P. Gosselin, July 7, 2019 in NoTricksZone


AMO cycle on the downward side: Red Sea to cool in the coming decades

By Die kalte Sonne
(German text translated by P Gosselin)

Seven years ago, in our book “The Forgotten Sun”, we proposed using ocean cycles for medium-term forecasts. At the time, the climate establishment was strictly opposed to this. Today fortunately times have changed.

On March 15, 2019, a team led by George Krokos analyzed the temperature development of the Red Sea in Geophysical Research Letters, which has become noticeably warmer in recent decades. The researchers put this into a long-term context and found a strong correlation with the 70-year ocean cycle of the AMO (Atlantic Multidecade Oscillation).

Now that AMO has reached its peak, Krokos and colleagues expect the Red Sea to cool in the next three decades.

Abstract:

Natural Climate Oscillations may Counteract Red Sea Warming Over the Coming Decades
Recent reports of warming trends in the Red Sea raise concerns about the response of the basin’s fragile ecosystem under an increasingly warming climate. Using a variety of available Sea Surface Temperature (SST) data sets, we investigate the evolution of Red Sea SST in relation to natural climate variability. Analysis of long‐term SST data sets reveals a sequence of alternating positive and negative trends, with similar amplitudes and a periodicity of nearly 70 years associated with the Atlantic Multidecadal Oscillation. High warming rates reported recently appear to be a combined effect of global warming and a positive phase of natural SST oscillations. Over the next decades, the SST trend in the Red Sea purely related to global warming is expected to be counteracted by the cooling Atlantic Multidecadal Oscillation phase. Regardless of the current positive trends, projections incorporating long‐term natural oscillations suggest a possible decreasing effect on SST in the near future.

Anchorage “Record” Was Not Actually A Record!

by P. Homewood, July 14, 2019 in NotaLotofPeopleKnowThat


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.

https://www.bbc.co.uk/news/world-us-canada-48890556

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:

Land’s complex role in climate change

by  Pielke et al., 2016 in PhysicsToday


To date, most reporting on climate has focused on the possibility of catastrophic warming due to carbon dioxide and other greenhouse gases released into the atmosphere. The assessment of climate change risk has essentially been distilled to a single metric: the global average surface temperature. That reality was evident at the 2015 United Nations Climate Change Conference in Paris, where the central negotiating point was whether the global temperature rise should be limited to 1.5 °C or 2 °C. Indeed, a 2016 opinion piece by Simon Lewis (University College London and the University of Leeds, UK) states that, “by endorsing a limit of 1.5 °C, the [Paris] climate negotiations have effectively defined what society considers dangerous.”

But the reality of humans’ impact on climate is exceedingly complex.2 Even if greenhouse gas emissions could be elimi- nated completely, other harmful anthropogenic sources of cli- mate change would remain. And even if global average tem- peratures were contained, human impacts on climate would manifest in other potentially dangerous ways.

One often overlooked human factor is land use. Deforestation, dry land farming, irrigated agriculture, overgrazing, and other alterations to the natural landscape can disrupt Earth’s natural balances and change weather patterns. As with the addition of CO2into the atmosphere, the effects can last for decades or longer and affect regions distant from the original offense. Given continued rapid population growth, they threaten to be irreversible.

Polar Bears Are Thriving Despite Global Warming: Here’s Why

by Susan J. Crockford, July 11, 2019 in ClimateChangeDispatch


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.

I have added a couple of figures to illustrate this English version of the essay.

Ice Box July: Unusual Cold, Surface Frost Sweep Across Central Europe!

by P. Homewood, July 10, 2019 in NotALotOfPeopleKnowThat


No Tricks Zone has the latest on the coldwave gripping much of Northern Europe. Following a new record low for July set in Lower Saxony last week, there are unconfirmed reports of a new record July low for the whole of the Netherlands:

From No Tricks Zone:

Where have all the globe-trotting climate ambulance chasers gone? Well, they’re nowhere to be found in Europe nowadays.

The reason is the unusual cold that has swept across a large swath of the continent and which has sent temperatures plummeting to near freezing.
