New Paper Claims Antarctica Had The ‘Most Intense Heat Wave Ever Recorded’. It Didn’t

by P. Gosselin, Sep 27, 2023 in ClimatChangeDispatch


On September 24th, 2023, Kasha Patel, a writer for The Washington Post (WaPo) created a story that is likely in the top 10 most false and egregious climate scare stories ever published.

Titled, “Scientists found the most intense heat wave ever recorded — in Antarctica,” the story isn’t just false, it is doubly so because the research paper it is based on is also seriously flawed. [emphasis, links added]

In this case, peer review at Geophysical Research Letters (GRL) failed to catch and correct the most basic abuse of the definition of a “heat wave.”

The leading paragraph of the WaPo story said:

In March 2022, temperatures near the eastern coast of Antarctica spiked 70 degrees Fahrenheit (39 degrees Celsius) above normal — making it the most intense recorded heat wave to occur anywhere on Earth, according to a recent study.

At the time, researchers on-site were wearing shorts and some even removed their shirts to bask in the (relative) warmth. Scientists elsewhere said such a high in that region of the world was unthinkable.

WaPo also provided a normal temperature, for reference with some “unbelievability” from the lead author of the paper.

Temperatures in March, marking a change into autumn on the continent, are typically around minus -54 degrees Celsius on the east coast near…Dome C. On March 18, 2022, temperatures peaked to minus -10 degrees Celsius. That’s warmer than even the hottest temperature recorded during the summer months in that region — “that in itself is pretty unbelievable,” said Blanchard-Wrigglesworth, an atmospheric scientist at the University of Washington.

First, it is important to point out that the so-called “heat wave” really wasn’t warm at all; the shorts and shirt removal were completely for show, rather than science.

Since most people in the United States use the Fahrenheit temperature scale, which isn’t mentioned at all in the WaPo article citing the actual high temperature recorded, it was easy for reporter Kasha Patel to sneak by the idea that it was actually warm at the time.

-10 Celsius is actually 14 degrees Fahrenheit – which isn’t warm, much less a “heat wave” by any definition. Patel can’t be forgiven for not mentioning this in the article because anyone can get the conversion simply by typing it into Google, like this example.

But that isn’t the worst journalistic violation Patel makes.

State of the climate – summer 2023

by J. Curry, Aug 15, 2023 in WUWT


A deep dive into the causes of the unusual weather/climate during 2023.  People are blaming fossil-fueled warming and El Nino, and now the Hunga-Tonga eruption and the change in ship fuels.  But the real story is more complicated.

Observations

Starting in June, the global temperatures are outpacing the record year 2016 (Figure 1).

Figure 1.  From Copernicus ECMWF

Here is the time series of the monthly surface temperature anomalies from the ERA5 reanalysis (Figure 2).  The July 2023 spike was of comparable magnitude to the winter 2016 anomaly which occurred in late winter.

Figure 2.

Here is the time series of the monthly lower atmospheric temperature anomalies from the UAH satellite-based analysis.  The July 2023 temperature anomaly remains slightly below the peak 2016 temperature anomalies and comparable to the peak 1998 temperature anomaly.

Figure 3. Plot from Roy Spencer

The spatial variation of July temperature anomalies is shown below (Figure 4). The ERA5 is the long-standing standard for global reanalyses; the JMA-Q3 (Japan) is a new product that uses a more sophisticated data assimilation process, and I expect it to be at least as good as the ERA5.  Superficially, the spatial variability looks pretty much the same, but it is informative to compare the regional amounts of warming which differ significantly between the two reanalyses. Warming is greatest in the Antarctic, and lowest in the Arctic. The warming is also very strong over the NH midlatitude oceans.

The polar regions are of particular interest. The Arctic sea ice is healthy – Arctic sea ice extent for July was only the twelfth lowest in the satellite record.  Greenland mass balance (snow accumulation minus melt) for July is above average relative to 1980-2010.  The Antarctic is a different story.  Antarctic winter sea ice is extremely low, much lower than any wintertime observations since the beginning of the satellite record in 1980.  The warm anomaly near Antarctica is an effect the reduced sea ice extent, not a direct cause. The Antarctic ozone hole is opening very early.

No, July Wasn’t The Warmest Month In Human History

by Dr M. Wielicki, Aug 14, 2023 in ClimateChangeDispatch


What’s going on?

During the last month, we were bombarded with headlines such as:

This month is the planet’s hottest on record by far – and hottest in around 120,000 years, scientists sayCNN, July 27, 2023

July 2023 ‘Virtually Certain’ To Be Hottest Month In Human HistoryForbes, July 27, 2023

So is there any validity to these claims… Was July the hottest month in human history? [emphasis, links added]

…snip…

Our civilization’s trajectory, from its humble beginnings in the wild to its current digital sophistication, serves as a testament to humanity’s relentless drive for advancement and ability to adapt.

The African Humid Period (AHP) and the rise of the Egyptian civilization…

The African Humid Period (AHP) is a climatic phase during the Holocene epoch characterized by much wetter conditions in large parts of Africa, especially the Sahara region, compared to the present day.

This significant shift in precipitation patterns had profound impacts on both the environment and early human societies of the continent.

The AHP roughly spanned from about 15,000 to 5,000 years ago, though exact timings can vary based on specific regions within Africa. It began at the end of the Last Glacial Maximum when ice sheets started retreating in the Northern Hemisphere.

One of the most dramatic manifestations of the AHP was the transformation of the Sahara desert. Today’s vast desert expanse was once a mosaic of grasslands, lakes, and rivers.

This “Green Sahara” supported a variety of wildlife, from large mammals like elephants and giraffes to a variety of fish in its waterways.

The wet conditions of the AHP supported a much denser human population in regions that are now desert. Archaeological evidence shows that these ancient Saharan communities engaged in fishing, hunting, cattle herding, and even agriculture.

The abundance of water and food allowed for relatively settled lifestyles compared to the more nomadic existences necessitated by the arid conditions that followed.

The primary driver behind the AHP is believed to be warmer summer temperatures and changes in the monsoon systems, which brought more rain to the African continent.

As these parameters shifted over millennia, the monsoons weakened, leading to the aridification of vast regions.

The African Humid Period serves as a reminder of the profound climatic variability our planet has experienced throughout relatively recent geological history at preindustrial levels of CO2, and the relative insensitivity of surface temperature and/or humidity and the concentration of GHG in the atmosphere.

A heatwave isn’t the end of the world

by T. Fazi, July 18, 2023 in UnHerd


As I write this, in my favourite local café in Rome, the temperature outside is close to 40°C. So yes, it’s hot. Yet, thanks to a relatively old invention — air conditioning — I’m able to work in comfort. The 10-minute bike ride back home will be tougher than usual, but it won’t kill me. Like most people here, I consider these temperatures to be a nuisance — but that’s about it.

According to the news, however, I should be terribly concerned — terrified, in fact. Everyone’s running headline stories about the “extreme”, “record-breaking” and “deadly” hot weather sweeping across Asia, the US and, most notably, Europe. Here, the heatwave was unofficially named Cerberus, the multi-headed dog that guards the gates of Hades, before being replaced by Charon, the man who ferries the dead there. Rome is being called the “infernal city”. To be honest, I can think of several much more hellish places around the world at the moment — cities plagued by poverty, terrorism and war. And yet we are told that the current heat waves are a taste of the “hell” that awaits us as a result of climate change.

Contradicting Data, Media Claim Canadian Wildfires And Heat Waves Made Worse By Climate Change

by H.S. Sterling, Jul 5, 2023 in ClimateChangeDispatch


Thus, it can’t be proof of climate change. And, as noted in Climate at a Glance: U.S. Heat Waves:

  • In recent decades in the United States, heat waves have been far less frequent and severe than they were in the 1930s.
  • The all-time high-temperature records set in most states occurred in the first half of the twentieth century.
  • The most accurate nationwide temperature station network, implemented in 2005, shows no sustained increase in daily high temperatures in the United States since at least 2005.

That’s right, neither heat waves nor wildfires, whether in Canada or elsewhere are getting worse.

The fear and actual damage generated by wildfires each year are bad enough without the bought-and-paid-for mainstream media making it worse by encouraging the misdirection of resources from taking actions that address the true causes of wildfires to the battle against climate change.

There is no evidence climate change has or will cause more heatwaves, droughts, or resulting wildfires

Intense, Long-Lasting Heatwaves Unfolding At The Bottom Of The Ocean

by G. Dickie, Mar 16, 2023 in ClimateChangDispatch


Heatwaves unfolding on the bottom of the ocean can be more intense and last longer than those on the sea surface, new research suggests, but such extremes in the deep ocean are often overlooked.

A team of scientists with the U.S. National Oceanic and Atmospheric Administration has conducted the first assessment of marine heatwaves along North America’s continental shelves.

They found that these bottom heatwaves ranged from 0.5 degrees Celsius to 3C warmer than normal temperatures and could last more than six months — much longer than heatwaves at the surface.

“We simply don’t have a ton of instruments on the ocean bottom along continental shelves,” said study co-author Dillon Amaya, an NOAA climate scientist. “The ocean is a powerful thing. It destroys instruments that we have in the water for too long.

Surface heatwaves can be picked up by satellites and can result in huge algal blooms.

No, Met Office–A Dry July Does Not Mean Climate Change.

by P. Homewood, July 30, 2022 in NotaLotofPeopleKnowThat


So far July 2022 has been the driest July in England since 1911. Up to 26 July there has been only 15.8mm of rain averaged across England; this is only 24% of the amount we would expect in an average July.

At this stage in the month we would expect to have seen well over three-quarters of the month’s rain to have already fallen in an average July.

The situation for the UK is a little better. As it stands, July 2022 is still the eighth driest July since 1836. With only 37.7mm of rain having fallen so far it is the driest July since 1984. Scotland has been closer to average in the north and west, but drier conditions have prevailed for south and east Scotland. Overall Scotland (71%), Wales (39%) and Northern Ireland (43%) have been dry, but the most extreme conditions are in East Anglia and southeast England.

Mark McCarthy, Head of the Met Office National Climate Information Centre, said: “It is not just July that has been dry. Since the start of the year, all months apart from February have been drier than average in the UK too. The result of this is that the winter, spring and summer of 2022 have all seen less than the UK average seasonal rainfall. 

“England has seen the lowest levels during these periods and, rainfall totals for the first six months of the year are around 25% below their long-term average, with the driest regions in the east and southeast.

UK heatwave: How do temperatures compare with 1976?

by P. Homewood, July 24, 2022 in NotaLotofPeopleKnowThat


People on social media have been comparing the high temperatures in much of the UK with the heatwave of 1976, suggesting that the severity of the current hot weather is being exaggerated.

So, what does the evidence show?

How hot was the summer of 1976?

The peak that year was 35.9C. That has been beaten by the current temperatures, with 40.3C recorded so far.

The heatwave of 1976 started in June and lasted for two months. There was a lack of rainfall and a significant drought, with the government enforcing water rationing.

The heatwave was rare for that decade. The average maximum temperature in July in the 1970s was 18.7C. In the 2010s, it was more than 20C.

The European Heat Wave and Global Warming

by Guest Blogger, July 21, 2022 in WUWT


From the Cliff Mass Weather Blog

There is a lot of talk about the short-term European heatwave with some suggesting that the record-breaking warmth is the result of climate change/global warming.

Some of the media and climate advocates have been over the top in their claims (see below), stating that this event was the result of human-caused global warming.

Was It Hotter In 1911?

by P. Homewood, July 23, 2022 in NotaLotofPeopleKnowThat


There has inevitably been a lot of apoplectic reporting about this week’s heatwave in Britain. Everybody from the BBC to the Met Office have been blaming it on climate change, with suitably scary colours to ram the message home:

Comparison of TV weather Maps from the BBC in summer 2012, left, and summer 2022 right. Source: BBC

Courtesy of Climate Realism

But so far I have not seen an objective analysis.

So let’s start with a few simple facts:

1) It was extremely hot for a couple of days this week.

2) The heat was the result of an extremely unlikely set of meteorological conditions – a perfect storm, if you like.

We know this because the Met Office told us so. On July 8th, they announced the possibility of a heatwave a week later. The weather model runs produced a wide band of possibilities, with most predicting similar temperatures to the weekend before, and some even forecasting no heatwave at all. At that stage on a couple of models out of the hundreds run predicted 40C temperatures, which were described by the BBC as “a very tiny possibility”.

 

The heatwave green hysteria is out of control

by P. Homewood, July 18, 2022 in NotaLotofPdeopleKnowThat


If you find yourself wondering over the next few days why it is so swelteringly hot, I have an answer for you. It’s because of rich people. It’s because of those wealthy elites with all their gas-guzzling vehicles and reckless holidaymaking. It’s their fault you’re sweating on the Tube.
This infantile claim really is being made, and by supposedly serious politicians. Labour’s Richard Burgon, over on his Instagram account, is wringing his no doubt sweaty hands over the filthy rich folk who apparently landed us in this weather apocalypse.
‘As we face 40C temperatures and the first ever Red Extreme Heat Warning, remember this climate crisis is driven by the wealthy’, he cries. His stern words are accompanied, naturally, by that Met Office map showing half of Britain coloured dark red – the hellish hue that has been chosen to illustrate how dire our predicament has allegedly become.
Is anyone else tiring of all this green hysteria over the heatwave? There is something medieval about it. There is something creepily pre-modern in the idea that sinful mankind has brought heat and fire and floods upon himself with his wicked, hubristic behaviour. What next – plagues of locusts as a punishment for our failure to recycle?

Think it’s hot now? How Britain roasted in TEN-WEEK heatwave during summer of ’76

by P. Homewood, Jul 15, 2022 in NotaLotofPeopleKnowThat


Wildfires have raged, speed restrictions have been imposed on some railway lines and hospitals have already declared ‘critical incidents’.

The hot weather in Britain this summer is set to peak next week, when the mercury could top 39C (102F) in London.

The current non-stop sunshine has evoked memories of the summer of 1976, when there were 15 consecutive days that saw temperatures of 89.6F (32C) somewhere in the UK.

Overall, there were ten weeks of blazing heat that saw widespread drought, mass standpipe use, and even the pausing of the murder trial of the notorious ‘Black Panther’, after a woman suffering from ‘heat exhaustion’ collapsed.

During a First Division football match between Manchester City and Aston Villa, City player collectively lost four stone in weight, prompting the team’s captain to call for an end to ‘summer soccer’.

At that year’s Wimbledon tennis championships, umpires were allowed to remove their jackets for the first time in living memory, whilst major roads were littered with broken-down cars that had overheated.

The extreme weather also caused an increase in the number of 999 callouts to domestic disturbances, as tempers buckled due to the heat.

The summer of 1976 was caused in part by very hot air that had originated in the Mediterranean. The warm weather and lack of rain began on June 23 and did not abate for more than a month.

The highest temperature recorded in the summer was on July 3, when the mercury hit 96.6F (35.9C) in Cheltenham. The average maximum daily temperature was 67.8F (19.9C).

What the media won’t tell you about U.S. heat waves

by R. Pielke Jr, June 16, 2022 in TheHonestBroker


It’s hot. Real hot. Heat waves in the United States surely must be the most visible and impactful sign of human caused climate change, right? Well, actually no. Let’s take a look at what the U.S. National Climate Assessment and the Intergovernmental Panel on Climate Change say about heat waves in the United States. What they say may surprise you.

Before proceeding, let me emphasize that human-caused climate change is real and significant. Aggressive policies focused on both adaptation and mitigation make very good sense. So too does being accurate about current scientific understandings. The importance of climate change does not mean that we can ignore scientific integrity — actually the opposite, it makes it all the more important. So let’s take a close look at recent assessment reports and what they say about U.S. heat waves.

The figure below comes out of the most recent U.S. National Climate Assessment(NCA). It shows the frequency (top) and intensity (bottom) of heat waves in the U.S. since 1900. The bottom figure is actually based on a paper that I co-authored in 1999, which serves as the basis for an official indicator of climate change used by the Environmental Protection Agency.

The Truth About Heat Waves

by Jime Steele, July 12, 2021 in WUWT


For those who truly want to be guided by science, put aside the climate crisis hysteria. We can explain the natural dynamics of all heat waves by simply knowing 1) how heat is transported along the earth’s surface; 2) how heat is transported vertically; 3) how solar heating changes; and 4) how the greenhouse effect varies.

Below is a map of global temperature anomalies for the year 2014 that illustrates natural climate dynamics. There is no uniform warming that might be expected from a global blanket of greenhouse gases. Across the globe, surface temperatures alternate between regions of above average warmth (red) with regions of below average (blue). (Gray regions lack sufficient data). Indeed, the observed cooler eastern USA is dubbed a “warming hole” by climate scientists because its cooling trend contradicts global warming theory. It requires a natural climate dynamic explanation.

The temperature pattern is associated with regions where warmer air from the south more frequently intruded northward, while simultaneously, cold air from the north intruded southward. This pattern is due to a naturally wavy jet stream and associated pressure systems. The warm red regions indicate regions where high‑pressure systems dominate. In the northern hemisphere, high pressure systems cause clockwise atmospheric circulation that pulls warm air northward on its western side, and cold air southward on its eastern side.  Low pressure systems circulate counter-clockwise, conversely pulling cold air southward on its western side. These combined circulation patterns partly explain both the extreme cold that dropped Texas temperatures as much as 50° F below average in February 2021, as well as extreme heating that raised USA’s northwest temperatures 30°- 40° F above normal the following June. Similarly in 2019, northward transport of heated air from the Sahara desert caused heat waves over Europe and Greenland. Such natural heat transport can also cause coastal Alaska to be warmer than Florida.

USA Heatwave reality check: Global temps below 30-year avg & ‘75% of the states recorded their hottest temperature prior to 1955’ – Worst U.S. heat waves happened in 1930s

by M. Morano, July 8, 2021 in CO2Coalition


Here we go again! Climate change: US-Canada heatwave ‘virtually impossible’ without warming according to climate model simulations

Model Based Study: Northwest heat wave impossible without climate change: “They logged observations of what happened and fed them into 21 computer models and ran numerous simulations. They then simulated a world without greenhouse gases from the burning of coal, oil and natural gas. The difference between the two scenarios is the climate change portion.”

Climate Depot’s Marc Morano & author of Green Fraud:

“Here we go again. Any heatwave, hurricane, tornado outbreak, etc. are always used by the media and other climate activists as some kind of ‘proof” of a climate emergency.  At least these claims are more plausible than claims that building collapses or illegal immigration are caused by “climate change.”

But currently, the global satellite temperature for June 2021 is below the 30-year average. And despite the U.S. heatwave, there are plenty of record cold outbreaks happening around the globe, (See: Unusually strong cold weather outbreak spreads from Antarctica into central South America, bringing early winter temperature records and first snowfall after decades)

The media gaslights anyone who mocks ‘global warming’ on a record cold or snowy day but has no problem doing the exact same thing whenever it’s hot. As University of Alabama climate scientist John Christy’s research has found: “About 75% of the states recorded their hottest temperature prior to 1955, and over 50 percent of the states experienced their record cold temperatures after 1940.”

In addition, the EPA’s own data has shown that the 1930s U.S. heatwaves were far more severe than current temperatures. (2021 Update: EPA puts inconvenient data on 1930s drought and heat wave down the memory hole)

In short, it is unscientific and nothing short of political lobbying to jump on a heatwave to claim ‘proof’ of man-made global warming. Climate activists’ new motto should be: Never let an opportunity go to waste to blame a heatwave or a flood or hurricane or building collapse or immigration — on ‘climate change.’

Was Global Warming The Cause of the Great Northwest Heatwave? Science Says No.

by C. Rotter, July 6, 2021 in WUWT


Reposted from The Cliff Mass Weather Blog

During the past week, the Pacific Northwest experienced the most severe heat event of the past century.

All-time high-temperature records were broken throughout the region, often by large margins. Many in the media, several local and national politicians, and some activist environmental scientists have claimed that this event was “driven by” or predominantly forced by human-inspired global warming (usually referred to as “climate change”).But such global warming claims are not supported by the facts and our best scientific understanding.  

Truth and Rigorous Science About Climate Change is Necessary for Wise Decisions
In this blog, I will use observations, modeling, climatological data, and the peer-reviewed scientific literature to demonstrate that human-caused global warming played a very small role in the extreme heat event that we just experienced here in the Pacific Northwest.I will describe the origins of a meteorological black swan eventand how the atmosphere is capable of attaining extreme, unusual conditions without any aid from our species.As you read this, consider that I have actively pursued research on Northwest heatwaves, published several papers in the peer-reviewed literature on this specific topic, and have run both weather prediction and climate models that simulate such events.  This subject is in my wheelhouse.

I also discuss the seriousness of misinformation.   You and others can not make wise decisions when the information provided to you is not based on truth and science.

Heatwave Reporting Shows How Science Has Been Corrupted By Climate Groupthinktch

by A. Watts, July 1, 2021 in ClimateChangeDispatch


The headline in E&E News, WOWT-TV, Scientific American, WorldNewsNetwork, and other media outlets this week, “Unprecedented Heat Wave in Pacific Northwest Driven by Climate Change” couldn’t possibly be more unscientific.

With absolutely no analysis, no historical context, and nothing but conjecture, author Anne. C. Mulkern eschewed science for advocacy in her reporting of the brief Pacific Northwest (PNW) heatwave this week.

Yes, the heatwave set all-time high-temperature records in Washington, Oregon, and Canada. But consider this: At best, we have about 150 years of reliable weather records for the PNW, so a “black swan” outlier eventlike this isn’t surprising.

It’s happened before, most certainly. We just weren’t around to observe it. After all, Native Americans did not keep written weather records.

High- (and low-) temperature records are nothing new. But it is important to look at the past because data shows us that more high-temperature records were set during the first half of the twentieth century than during the past 50 years.

Even the Environmental Protection Agency (EPA) confirms this.

Climate Change, Lies And The Lancet

by P. Homewood, January 7, 2020 in ClimateChangeDispatch


The Lancet has published its latest annual report on health and climate change, which inevitably orders us to stop using fossil fuels or the kids will get it!

It is the usual load of overhyped rubbish of the sort we have seen in previous years.

The executive summary contains a number of questionable claims and statements which seriously undermine the report’s integrity and reliability.

For a start, it claims that ‘a child born today will experience a world that is more than four degrees warmer than the pre-industrial average.’

Really? A temperature rise of three degrees in 50 years or so? Even the highly discredited climate models don’t regard this as realistic. For the Lancet to state this as a bald-faced fact calls into question the objectivity of its contents.

It then proceeds to list all sorts of ways in which health is already being impacted by climate change, including disease transmission, air pollution, extreme weather (which apparently will affect women more – yes, that’s got me and all!), wildfires, heatwaves and goodness knows what else.

Yet, tucked away in Figure 5 is the dirty little secret that mortality rates from climate-related causes have been plummeting since 1990.

The Gestalt of Heat Waves

by Clyde Spencer, Sep. 6, 2019 in WUWT


Abstract

Tmax and Tmin time-series are examined to look for historical, empirical evidence to support the claim that heat waves will become more frequent, of longer duration, and with higher temperatures than in the past. The two primary parameters examined are the coefficient of variation and the difference between Tmax and Tmin. There have been periods in the past when heat waves were more common. However, for nearly the last 30 years, there has been a reversal of the correlation of increasing CO2 concentration with the Tmax coefficient of variation. The reversal in differences in Tmax and Tmin indicate something notable happened around 1990.

Introduction

There was much in the press this Summer about the ‘global’ heat waves, particularly in France and Greenland. For an example of some of the pronouncements, see here. The predictions are that we should expect to see heat waves that are more frequent and more severe because of Anthropogenic Global Warming, now more commonly called “Climate Change.” The basis for the claim is unvalidated Global Climate Models, which are generally accepted to be running to warm. The simplistic rationale is that as the nights cool less, it takes less heating the next day to reach unusually high temperatures. Unfortunately, were that true, that would lead one to conclude that heat waves should never stop.

If the predictions of worse future heat waves were valid, one might expect to be able to discern a change occurring already, inasmuch as it is commonly accepted that Earth has been warming at least since the beginning of the Industrial Revolution

Recent global heat waves are correlated to an exceptional solar cycle 24

by J. Van Vliet, Sep. 5, 2019 in ScienceClimatEnergie


Belgium and France were recently affected by an extreme heat wave that took place between 24 and 27 July 2019. This heat wave was in many aspects presented as unprecedented and it has therefore unlocked a large scale reaction by many media. After a few days to cool down, the time has come to express a non-emotional and non-political opinion about such a strong heat wave.

Emotional reactions were normal in such circumstances: the temperatures were extreme and even if France and Belgium were much better prepared that for the 2003 heat wave, the present heat wave has led to important suffering for many poor people or people in bad health and without access to air conditioning.

The heat wave unlocked also many political reactions: it was an opportunity to press once more the threatening mantra of United Nations[1] and IPCC that mankind is responsible for this catastrophic warming and is destroying its own and only planet. A whole caste of politicians, countless academics and so-called “experts”, lobbyists, bureaucrats and NGOs claim that it is urgent to take “strong” measures going up to the replacement of democracy by climatist[2] despotism: even children are enlisted in the political arena. These people number in hundreds of thousands and probably more and they communicate loudly and repeatedly at the UN, through IPCC reports and COP events, in the media and in the streets. Does this imply they are right ? Has mankind something to do with these high temperatures ?

Summer Heatwaves? It Was Hotter In 1707!!

by P. Homewood, Sept.2, 2019 in NotaLotofPeopleKnowThat


To read the headlines in the last month or two, you would think we had been having a Mediterranean summer.

The truth is much more mundane however.

The numbers for last month’s CET are now out. August ended up at 17.1C, meaning that there have been 32 Augusts as warm or warmer. Last month was no warmer than 1801, 1842 and 1932.

Summer as a whole ranked 48th hottest, tied with 1935.

The summer of 1976 still remains top of the list, but second hottest was way back in 1826.

Indeed there have been warmer summers on 28 occasions prior to 1900. Notably, one such summer was 1666, the 18th warmest. That was, of course, the year of the Great Fire of London, which swept through London between the 2nd and 6th of September.

What Greenland Heatwave?

by P. Homewood, September 1, 2019 in NotaLotofPeopleKnowThat


Let’s start with Qaanaaq (Thule), which the Mirror reporter visited during w/e 25th August. She wrote:

 

A heatwave is gripping The Arctic, melting away Greenland’s ice sheet on an unprecedented scale and threatening a global rise in sea levels – an urgent reminder of the climate crisis we are now all facing.

Kids splashing each other in the sea and locals wearing t-shirts were unheard of here in August 10 years ago.

But now, alongside teenage girls wearing skirts to school and increasing mosquitoes, it is a common occurrence for the residents of Qaanaaq, in north-west Greenland, one of the world’s most northerly cities situated 700 miles north of the Arctic Circle.

This is the frontline of climate change…..

The country is also experiencing record-breaking temperatures. In mid-June, along the eastern coast it was 9C warmer than the 1981-2010 average.

Just as western Europe has baked in a heatwave with record temperatures at the end of July, the hot air moved as far north as Greenland with the gauge hitting 22C on August 1. The average high is around 7C….

 

According to Weather Underground, however, daily maximum temperatures at Qaanaaq never got above 47F that week. The highest temperature of the month was 63F on the 1st.

KNMI confirm that the record temperature at Qaanaaq is 67F, and that a temperature of 63F was also recorded way back in 1959.

Northern Europe July Temperature Sees NO WARMING Over Past Decades. Global July Not A Record High!

by P. Gosselin, August 20, 2019 in NoTricksZone


Parts of Europe have seen a couple of brief but intense heat waves this summer, and so some of the public got brainwashed by the media into thinking the continent’s summer climate is rapidly getting hotter and that all this is the new normal.

Yet, when we examine the unaltered data from the Japan Meteorology Agency (JMA) for locations in northern Europe that have long-term datasets available, we see there has been no July warming trend over the past decades. Media reports suggesting otherwise are nonsense.

Ireland

Looking at 6 stations in Ireland, we have the following for July:

 

Data source: JMA.

Overall, Ireland’s mean July temperatures have been cooling off modestly over the past 3 decades and more, even though three stations are located at airports.

As I’m sure many of my readers are aware, Europe has been having an odd summer as far as temperatures are concerned. The continent has had two major heatwaves this summer; one was in June and the other was in July.

In addition, Greenland has also seen some exceptional “warmth” and lots of ice melt this summer as compared to more recent years.

So, what’s going on? Is climate change to blame? Or, is this a freak of nature?

As with most complicated things in science, the truth is somewhere in between and is not just one way or the other. I hate saying that as a “black and white” person, but it’s an unfortunate fact. One can not make a preconceived notion based on one weather event without looking at a.) the big picture, b.) mechanism, and c.) long-term trends.

The upper air pattern over Europe and Greenland is opposite of what’s been occurring in much of the United States. The U.S. has only had one major heatwave this year, and that in and of itself caused mass hysteria.
