German Climatologist Werner Kirstein Unloads: “IPCC Is To Deceive People”…Calls Michael Mann’s Chart “A Fake”

by P. Gosselin, Sep.17, 2019  in NoTricksZone

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.

A Skeptic’s Guide To Global Temperatures

by Clive Best, August 30, 2019 in ClimateChangeDispatch

Climate change may well turn out to be a benign problem rather than the severe problem or “emergency” it is claimed to be.

This will eventually depend on just how much the Earth’s climate is warming due to our transient but relatively large increase in atmospheric CO2 levels.

This is why it is so important to accurately and impartially measure the Earth’s average temperature rise since 1850. It turns out that such a measurement is neither straightforward, independent, nor easy.

For some climate scientists, there sometimes appears to be a slight temptation to exaggerate recent warming,  perhaps because their careers and status improve the higher temperatures rise.

NASA: We Can’t Model Clouds, So Climate Model Projections Are 100x Less Accurate

by K. Richard, August 30, 2019 in ClimateChangeDispatch

NASA has conceded that climate models lack the precision required to make climate projections due to the inability to accurately model clouds.

Clouds have the capacity to dramatically influence climate changes in both radiative longwave (the “greenhouse effect”) and shortwave.

Cloud cover domination in longwave radiation

In the longwave, clouds thoroughly dwarf the CO2 climate influence. According to Wong and Minnett (2018):

  • The signal in incoming longwave is 200 W/m² for clouds over the course of hours. The signal amounts to 3.7 W/m² for doubled CO2 (560 ppm) after hundreds of years.

  • At the ocean surface, clouds generate a radiative signal 8 times greater than tripled CO2 (1120 ppm).

  • The absorbed surface radiation for clouds is ~9 W/m². It’s only 0.5 W/m² for tripled CO2 (1120 ppm).

  • CO2 can only have an effect on the first 0.01 mm of the ocean. Cloud longwave forcing penetrates 9 times deeper, about 0.09 mm.


Climate Scientists Admit Their Models Are Wrong

by Bud Bromley, August 30, 2019 in PrincipiaScientificInternational

Climate scientists who support human-caused global warming, for example Ben Santer and Michael Mann, authored a peer reviewed paper which acknowledges that their climate models are wrong, although their admission is buried in weasel words and technical jargon:

In the scientific method it is not the obligation or responsibility of skeptics or “deniers” to falsify or disprove hypotheses and theories proposed by climate scientists.  It is the obligation and responsibility of climate scientists to present evidence and to defend their hypothesis.  Alarmist climate scientists have failed to do so despite the expense of billions of dollars of taxpayer money.


How the Media Help to Destroy Rational Climate Debate

by Dr Roy Spencer, August 25, 2019 in GlobalWarming

An old mantra of the news business is, “if it bleeds, it leads”. If someone was murdered, it is news. That virtually no one gets murdered is not news. That, by itself, should tell you that the mainstream media cannot be relied upon as an unbiased source of climate change information.

There are lots of self-proclaimed climate experts now. They don’t need a degree in physics or atmospheric science. For credentials, they only need to care and tell others they care. They believe the Earth is being murdered by humans and want the media to spread the word.

Most people do not have the time or educational background to understand the global warming debate, and so defer to the consensus of experts on the subject. The trouble is that no one ever says exactly what the experts agree upon.

When you dig into the details, what the experts agree upon in their official pronouncements is rather unremarkable. The Earth has warmed a little since the 1950s, a date chosen because before that humans had not produced enough CO2 to really matter. Not enough warming for most people to actually feel, but enough for thermometers to pick up the signal buried in the noise of natural weather swings of many tens of degrees and spurious warming from urbanization effects. The UN consensus is that most of that warming is probably due to increasing atmospheric CO2 from fossil fuel use (but we really don’t know for sure).

For now, I tend to agree with this consensus.

And still I am widely considered a climate denier.

Why? Because I am not willing to exaggerate and make claims that cannot be supported by data.

The widely reported Greenland surface melt event around 1 August 2019 (green oval) was then followed by a recovery to normal in the following weeks (purple oval), which was not reported by the media.

Amazon Fire History Since 2003

by Les Johnson, August 23, 2019 in WUWT

We are told that Amazon fires are at record levels right now. This is a blatant lie. The only “record” is that Amazonian fires have DECREASED over the “record”.

This (is) what the data actually looks like, to August 22. Yes, its updated daily.

This comes from a wonderful site,

It uses NASA MODIS data, from the Terra and Aqua satellites, and is updated daily. By going to the website, you can look at individual regions in the Amazon, or as I have done, look at the totals for the Amazon. This site also has global data, but I am only looking at the Amazon region here.

The Interactive Graphs are very informative. Hovering the cursor over the graph will show the data at that point.

You can highlight individual years, by clicking on a year in the legend at the bottom of the graph. That year remains bright, while the rest are dimmed. Using Eyeball Mark 1 Trend Indicator (EBM1TI), 2019 is slightly high, but not at record levels. Not even close.

One thing I saw by looking at each year, was a rough pattern – one or two bad years, one or two years at much lower levels, then a bad year. This pattern is there until 2010. 2010 was the last “bad year”. Levels since 2010 have been 1/2 or less of the “bad years”. The old pattern has been broken.

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.


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.


Ten Causes of Warming: The Layperson’s Checklist

by Jim Steele, August 8, 2019 in WUWT

All temperatures are not created equally. Rising temperatures have many causes. Good science demands we explore alternative hypotheses before reaching any conclusions. Below is a list of common causes of warming trends and heat events that everyone should consider in addition to any possible increased greenhouse effect.

1. Heat trapping surfaces: Asphalt and cement not only heat up much faster than natural habitat during the day, those materials hold the heat longer, increasing temperatures at weather stations situated near buildings and near asphalt. More asphalt, more warming, more record temperatures.

2. Loss of Vegetation: During the summer the temperature of a dry dirt road can be 60°F higher at noon, than ground shaded by trees. That’s why our pets instinctively seek the shade. Plants also bring moisture from below the ground that cools the air by evaporative cooling. Increasing deforestation or lost vegetation due to landscape changes cause regional warming trends.

3. Transport of heat: Natural climate oscillations alter air and ocean circulation patterns that can drive more heat from the tropics towards the poles. Europe’s recent heat wave was largely caused by air heated over the baking Sahara Desert and then driven into Europe. Similarly, the latest research finds variations in Arctic sea ice has been dominated by transport of warm Atlantic water heated in the tropics and transported northward via the Gulf Stream.

4. Less cloud cover: Recent research suggests a trend of less cloud cover resulted in increased solar heating of land and oceans. The added solar energy normally reflected by clouds was 2 times greater than what’s believed to be added by increasing carbon dioxide. Two decades of declining cloud cover was similarly shown to cause Greenland’s rapid ice melt between 1995 and 2012.

5. Less Cooling: Windy conditions cool the oceans. The unusually warm ocean conditions that occurred in the northwestern Pacific Ocean, known as the Blob, were caused by decreased winds that reduced normal cooling.

For Most Of The Last 10,000 Years, Greenland Ice Sheet and Glacier Volume Was Smaller Than Today

by K. Richard, August 5, 2019 in NoTricksZone

A new paper (Axford et al., 2019) reveals NW Greenland’s “outlet glaciers were smaller than today from ~9.4 to 0.2 ka BP” (9,400 to 200 years before 1950), and that “most of the land-based margin reached its maximum Holocene extent in the last millennium and likely the last few hundred years.”

The authors conclude:

“We infer based upon lake sediment organic and biogenic content that in response to declining temperatures, North Ice Cap reached its present-day size ~1850 AD, having been smaller than present through most of the preceding Holocene.”

Furthermore, the authors assert Greenland was 2.5°C to 3°C warmer than modern on average during the Holocene Thermal Maximum, and peak temperatures were 4°C to 7°C warmer.

Why You Shouldn’t Draw Trend Lines on Graphs

by Kip Hansen,  August 6, 2019 in WUWT

What we call a graph is more properly referred to as “a graphical representation of data.”  One very common form of graphical representation is “a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.”

Here at WUWT we see a lot of graphs —  all sorts of graphs of a lot of different data sets.  Here is a commonly shown graph offered by NOAA taken from a piece at called “Did global warming stop in 1998?” by Rebecca Lindsey published on September 4, 2018.


I am not interested in the details of this graphic representation — the whole thing qualifies as “silliness”.  The vertical scale is in degrees Fahrenheit and the entire range change over 140 years shown is on the scale 2.5 °F or about a degree and a half C.   The interesting thing about the graph is the effort of drawing of “trend lines” on top of the data to convey to the reader something about the data that the author of the graphic representation wants to communicate.  This “something” is an opinion — it is always an opinion — it is not part of the data.

The data is the data.  Turning the data into a graphical representation (all right, I’ll just use “graph” from here on….), making the data into a graph has already  injected opinion and personal judgement into the data through choice of start and end dates, vertical and horizontal scales and, in this case, the shading of a 15-year period at one end.  Sometimes the decisions as to vertical and horizontal scale are made by software — not rational humans —  causing even further confusion and sometimes gross misrepresentation.

Anyone who cannot see the data clearly in the top graph without the aid of the red trend lineshould find another field of study (or see their optometrist).  The bottom graph has been turned into a propaganda statement by the addition of five opinions in the form of mini-trend lines.

Relation entre l’ activité sismique dans les océans et le réchauffement global (août 2019)

c/o Luc Trullemans,  août 2019 in PublicMétéo


Une forte relation à été observée ces dernières années entre de l’activité sismique dans les océans et le récent réchauffement climatique  (CSARGW ,Correlation of Seismic Activity and Recent Global Warming) .

Cette corrélation entre de l’activité sismique océanique et le réchauffement climatique avait déjà été remarquée de 1979 à 2016 (CSARGW16) et vient d’être confirmée jusqu’en 2018.

Dans cette note, on démontre que  l’activité sismique dans les océans ( =>tremblements de terre de magnitude 4-6) provoque des flux géothermiques sous-marins et ont une relation importante avec les fluctuations de la température globale des océans (SST) et de la température globale de l’air (GT).

Ceci avance une nouvelle l’hypothèse selon laquelle l’activité sismique océanique pourrait être  un des paramètres  les plus importants dans la variation de la température globale.



Hockey Stick Groundhog Day

by P. Homewood, August, 1, 2019 in NotaLotofPeopleKnowThat

Some ancient history

Fifteen to twenty years ago, Michael Mann and colleagues wrote a few papers claiming that current warming was unprecedented over the last 600 to 2000 years.  Other climate scientists described Mann’s work variously as crap, pathetic, sloppy, and crap.  These papers caught the interest of Stephen McIntyre and this led to the creation of his Climate Audit blog and the publication of paperspointing out the flaws in these hockey stick reconstructions. In particular, Mcintyre and his co-author Ross McKitrick showed that the method used by Mann and colleagues shifted the data in such a way that any data sets that showed an upward trend in the 20th century would receive a stronger weighting in the final reconstruction.  With this method, generation of a hockey-stick shape in the temperature reconstruction was virtually guaranteed, which M&M demonstrated by feeding in random numbers to the method.

Former Award-Winning NOAA scientist Dr. Rex Fleming declares his climate dissent

by Marc Morano, July 30, 2019 in Climate Depot,

Former NOAA Award-Winning Atmospheric Scientist Dr. Rex Fleming joins many former UN IPCC and U.S. government scientists publicly dissenting on man-made climate change. Fleming declares that “CO2 has no impact on climate change.”

“Past climates have been warm and cold and warm and cold with no changes in carbon dioxide. How can that be a cause when there’s no correlation.”

Fleming 8:10 on AMS, AGU, AAAS: “all 3 of those organizations will not support a “denier”..I could not get published in any of those a denier..I had to go to Europe to publish a was peer-reviewed in Europe, it got thru, & it has been very successful”

Anti science L. A. Times hypes propaganda denying global wide Medieval Warm Period and Little Ice Age

by Larry Hamlin, July 28, 2019 in WUWT

The Los Angeles Times is at it again hyping anti science climate alarmist propaganda trying to conceal the global wide Medieval Warm Period and the Little Ice Age that are supported and justified by hundreds of scientific studies.

This climate alarmist propaganda Times article cites a new “study” that ridiculously attempts to deny these clearly established warm and cool periods in our past.

This alarmist hyped new “study” is addressed in a superb article at the JoNova website demonstrating the complete lack of scientific veracity of this studies claims.

There is nothing I can add to show how politically contrived and inane the claims are from this new “study” beyond the excellent presentation in the JoNova article.

Provided below are excerpts from this excellent article which demonstrate the lack of scientific credibility of the new “study” as well as the politically driven anti science climate alarmism bias of the Times.


1970s: Earth Warmed 0.6°C From 1880-1940 And Cooled -0.3°C From 1940-1970. Now It’s 0.1°C And -0.05°C.

by K. Richard, July 25, 2019 in NoTricksZone

About 45 years ago, the “consensus” in climate science (as summarized by Williamson, 1975) was quite different than today’s version.

1. The Medieval Warm Period was about 1°C warmer than present overall while the “largely ice-free” Arctic was 4°C warmer, allowing the Vikings to navigate through open waters because there was “no or very little ice” at that time.
2. The island of Spitsbergen, 1237 km from the North Pole and home to over 2000 people, “benefited” because it warmed by 8°C between 1900 and 1940, resulting in 7 months of sea-ice free regional waters. This was up from just 3 months in the 1800s.
3. Central England temperatures dropped -0.5°C between the 1930s to the 1950s.
4. Pack-ice off northern and eastern iceland returned to its 1880s extent between 1958 and 1975.
5. In the 1960s, polar bears were able to walk across the sea (ice) from Greenland to Iceland for the first time since the early 1900s. (They had somehow survived the 7 months per year of sea-ice-free waters during the 1920s-1940s).
