2019 Science Refutes Climate Alarm On Every Front… Shrinking Deserts, Growing Islands, Crumbling Consensus, Weaker Storms, Cooler Arctic Etc. Etc. Etc.

by P. Gosselin, December 31, 2019 in NoTricksZone

2019 science: Absolutely no climate alarm 

No alarm on every aspect: stable polar ice, normal sea level rise, no consensus, growing snow cover, less tropical storms, tornadoes, shrinking deserts, global greening, predictions wrong, models flawed, climate driven by sun, ocean cycles, biodiversity, warmer 1000 years ago…etc…


2019 saw a great amount of new science emerge showing that there’s nothing alarming or catastrophic about our climate. 

Some 2019 scientific findings

Need to make a presentation showing there is no climate alarm? The following findings we reported on in 2019 will put many concerns to rest.

Hundreds of peer-reviewed papers ignored by media

What follows are some selected top science-based posts we published here at NoTricksZone in 2019. These new findings show there is absolutely no climate alarm.

Hundreds of new peer-reviewed papers, charts, findings, etc – which the IPCC, activists and media ignore and even conceal. No wonder they’ve gotten so shrill.


Comprehensive Data, Recent Studies In Top Journals: Antarctica Stable, Temps Falling, Ice Mass Growing!

by P. Gosselin, January 14, 2020 in NoTricksZone

The ice in Antarctica, how is it doing? Is it melting, is it growing? In the following we wishto present the latest literature on the subject. There is a lot to report.

Fasten your seat belt, there’s a lot to cover.

Let’s start with the temperature development because along with snowfall, this is the most important control factor for Antarctic inland ice.

At NoTricksZone, Kirye shows ten coastal stations of Antarctica. None have been warming over the past 10 years. An example follows:


And here’s the temperature development of the entire Antarctic according to UAH and RSS satellite measurements (from Climate4You, via NoTricksZone):

NASA: 2020 Will Mark the Lowest Solar Activity in 200 Years

by James Murphy, January 16, 2020 in NewAmerican

With all of the pseudo-scientific propaganda being peddled about anthropogenic climate change, people sometimes forget that there are other, far more important drivers of the Earth’s climate than mankind’s carbon dioxide emissions. For example, that big ball of yellow light in the sky (aka the sun) has a huge effect on climate. And according to NASA, this year will mark the lowest level of solar activity in 200 years.

“Research now underway may have found a reliable new method to predict this solar activity. The Sun’s activity rises and falls in an 11-year cycle. The forecast for the next solar cycle says it will be the weakest of the last 200 years. The maximum of this next cycle — measured in terms of sunspot number, a standard measure of solar activity level — could be 30-50 percent lower than the most recent one. The results show that the next cycle will start in 2020 and reach its maximum in 2025.”

According to a growing number of scientists, the coming lower solar cycle — number 25 — may simply be a precursor to a period of prolonged solar minima such as the Maunder and Spörer minimums of the past millennium.


Major Greenland Glacier Is Growing

by NASA (Earth Observatory), June 6, 2019 in NASA.E.Observ.

Jakobshavn Glacier in western Greenland is notorious for being the world’s fastest-moving glacier. It is also one of the most active, discharging a tremendous amount of ice from the Greenland Ice Sheet into Ilulissat Icefjord and adjacent Disko Bay—with implications for sea level rise. The image above, acquired on June 6, 2019, by the Operational Land Imager (OLI) on Landsat 8, shows a natural-color view of the glacier.

Jakobshavn has spent decades in retreat—that is, until scientists observed an unexpected advance between 2016 and 2017. In addition to growing toward the ocean, the glacier was found to be slowing and thickening. New data collected in March 2019 confirm that the glacier has grown for the third year in a row, and scientists attribute the change to cool ocean waters.

“The third straight year of thickening of Greenland’s biggest glacier supports our conclusion that the ocean is the culprit,” said Josh Willis, an ocean scientist at NASA’s Jet Propulsion Laboratory and principal investigator of the Oceans Melting Greenland (OMG) mission

Gavin’s Falsifiable Science

by Willis Eschenbach, January 18, 2020 in WUWT


Folks are interested in why the temperature of the planet changes over time. That’s at the center of modern climate science. My theory, on the other hand, arose from my being interested in a totally different question about climate—why is the temperature so stable? For example, over the 20th Century, the temperature only varied by ± 0.3°C. In the giant heat engine that is the climate, which is constantly using solar energy to circulate the oceans and the atmosphere, this is a variation of 0.1% … as someone who has dealt with a variety of heat engines, I can tell you that this is amazing stability. The system is ruled by nothing more solid than waves, wind, and water. So my question wasn’t why the climate changes as it does.

My question was, why is the climate so stable?

And my answer is, there are a host of what are called “emergent phenomena” that arise when local temperatures go above some local threshold. They include the timing and strength of the daily emergence of the cumulus cloud field in the tropics; the development of thunderstorms; the emergence of dust devils when temperatures get hot; the action of the El Nino/La Nina pump moving warm water to the poles; and various “oscillations” like the Pacific Decadal Oscillation.

These emergent phenomena arise out of nowhere, last for some length of time, and then disappear completely. And acting together, they all work to prevent both the overcooling and the overheating of the planet. And as mentioned above, I say that these phenomena acted to reduce the length and the depth of the effect of the Pinatubo volcano. See my post called “When Eruptions Don’t” for another look at how the climate system responds to a decrease in incoming solar energy due to volcanic eruptions.


I originally published this theory in the journal Energy and Environment. I followed that up with a posting of the same ideas here at Watts Up With That in a post called The Thermostat Hypothesis.

New 80-Year Deep-Ocean Temperature Dataset Compared to a 1D Climate Model

by Roy Spencer, January 15, 2020 in WUWT/Ch.Rotter

The increasing global ocean heat content (OHC) is often pointed to as the most quantitative way to monitor long-term changes in the global energy balance, which is believed to have been altered by anthropogenic greenhouse gas emissions. The challenge is that long-term temperature changes in the ocean below the top hundred meters or so become exceedingly small and difficult to measure. The newer network of Argo floats since the early 2000s has improved global coverage dramatically.

A new Cheng et al. (2020) paper describing record warm ocean temperatures in 2019 has been discussed by Willis Eschenbach who correctly reminds us that such “record setting” changes in the 0-2000 m ocean heat content (reported in Zettajoules, which is 10^^21 Joules) amount to exceedingly small temperature changes. I calculate from their data that 2019 was only 0.004 0.009 deg. C warmer than 2018.

Over the years I have frequently pointed out that the global energy imbalance (less than 1 W/m2) corresponding to such small rates of warming is much smaller than the accuracy with which we know the natural energy flows (1 part in 300 or so), which means Mother Nature could be responsible for the warming and we wouldn’t even know it.

The Cheng (2017) dataset of 0-2000m ocean heat content changes extends the OHC record back to 1940 (with little global coverage) and now up through 2019. The methodology of that dataset uses optimum interpolation techniques to intelligently extend the geographic coverage of limited data. I’m not going to critique that methodology here, and I agree with those who argue creating data where it does not exist is not the same as having real data. Instead I want to answer the question:

If we take the 1940-2019 global OHC data (as well as observed sea surface temperature data) at face value, and assume all of the warming trend was human-caused, what does it imply regarding equilibrium climate sensitivity (ECS)?

Fig. 1. Deep-ocean temperature variations 1940-2019 explained with a 2-layer energy budget model forced with RCP6 radiative forcing scenario and a model climate sensitivity of 1.85 deg. C. The model also matches the 1940-2019 and 1979-2019 observed sea surface temperature trends to about 0.01 C/decade. If ENSO effects are not included in the model, the ECS is reduced to 1.7 deg. C.

19 Papers Published In 2019 Affirm Sea Levels Were METERS Higher Than Today 4-8 Thousand Years Ago

by K. Richard, January 16, 2020 in NoTricksZone

The onslaught of paleoclimate evidence for warmer-than-now Mid-Holocene climates – when the Earth’s sea levels were meters higher than they are today –  stormed through 2019.

There were 107 scientific papers published this past year indicating today’s warmth isn’t even close to being unusual or unprecedented when compared to the climates of the last centuries to millennia.

As illustrated below, there were also 19 papers affirming today’s sea levels are among the lowest of the last ~8000 years.

This is added to the list of nearly 100 scientific papers published in the last handful of years indicating Mid-Holocene sea levels were multiple meters higher than they are today due to the much more extensive glacier and ice sheet melt occuring during these millennia.

Throwing More Cold Water On An Alarmist Ocean-Warming Paper

by Dr. D. Whitehouse, January 17, 2020 in ClimateChangeDispatch

It’s the usual story. It’s the beginning of the year and the statistics of the previous year are hurriedly collected to tell the story of the ongoing climate crisis.

First off, we have the oceans which, according to some, are living up to the apocalyptic narrative better than the atmosphere.

The atmosphere is complicated, subjected to natural variabilities, that make the temperature increase open to too much interpretation.

The oceans, however, are far more important than the air as they absorb most of the anthropogenic excess heat.

Looking at the literature reveals no one knows just how much excess heat (created in the atmosphere) it mops up or indeed exactly how or where it does it. Some say it is 60% which is a bit on the low side, most say 90% or 93%.

The real figure is unknown though it should be noted that a few percent errors translate to a lot of energy, about the same amount that is causing all the concern.

On 14 January the Guardian had the headline, “Ocean temperatures hit record high as the rate of heating accelerates.” The study that reached this conclusion was published in the journal Advances in Atmospheric Sciences.

It’s a badly written paper full of self-justifying statements and unwarranted assumptions that should have been stripped-out by the editor.

While NOAA/NASA claims 2019 as the “second warmest year ever”, other data shows 2019 cooler than 2005 for USA.

by Anthony Watts, January 15, 2020 in WUWT

Today, at the big 100 year anniversary shindig of the American Meteorological Society (AMS) there was a press release session that featured NOAA and NASA GISS talking about how their climate data says that the world in 2019 was the second warmest ever.

Here is their slideshow presentation, released today:

In my opinion, the NOAA/NASA press release (and slideshow) is inconsistently presented. For example, they can’t even agree on a common base period for comparisons. Some graphs use 1951-1980 while others compare to 1981-2010 averages to create anomaly plots. NOAA and NASA owe it to the public to present climate data with a consistent climate period for comparison, otherwise it’s just sloppy science. NASA GISS has consistently resisted updating the 1951-1980 NASA GISS baseline period to the one NOAA and other datasets use, which is 1981-2010. GISS stubbornly refuses to change even though they have been repeatedly excoriated for keeping it.

That 1951-1980 period just so happens to be the coolest period in the 20th century, so by using that as a baseline, the peak amount of warming anomaly is magnified in NASA GISS plots. Most laymen will never spot this. A simple comparison of the two maps show the difference in the peak values:


The Ocean Warms By A Whole Little

by Willis Eschenbach, January 4, 2020 in WUWT

How much is a “Whole Little”? Well, it’s like a whole lot, only much, much smaller.

There’s a new paper out. As usual, it has a whole bunch of authors, fourteen to be precise. My rule of thumb is that “The quality of research varies inversely with the square of the number of authors” … but I digress.

In this case, they’re mostly Chinese, plus some familiar western hemisphere names like Kevin Trenberth and Michael Mann. Not sure why they’re along for the ride, but it’s all good. The paper is “Record-Setting Ocean Warmth Continued in 2019“. Here’s their money graph:


Figure 1. Original Caption: “Fig. 1. (a) Upper 2000 m OHC from 1955 through 2019. The histogram represents annual anomalies (units: ZJ), wherein positive anomalies relative to a 1981−2010 baseline are shown as red bars and negative anomalies as blue. The two black dashed lines are the linear trends over 1955–86 and 1987−2019, respectively.”


So here’s the hot news. According to these folks, over the last sixty years, the ocean has warmed a little over a tenth of one measly degree … now you can understand why they put it in zettajoules—it’s far more alarming that way.

Next, I’m sorry, but the idea that we can measure the temperature of the top two kilometers of the ocean with an uncertainty of ±0.003°C (three-thousandths of one degree) is simply not believable.

Weak El Nino Conditions Help Explain Recent Global Warmth

by Dr. Roy Spencer,  January 13, 2020 in WUWT

The continuing global-average warmth over the last year has caused a few people to ask for my opinion regarding potential explanations. So, I updated the 1D energy budget model I described a couple years ago here with the most recent Multivariate ENSO Index (MEIv2) data. The model is initialized in the year 1765, has two ocean layers, and is forced with the RCP6 radiative forcing scenario and the history of El Nino and La Nina activity since the late 1800s.

The result shows that the global-average (60N-60S) ocean sea surface temperature (SST) data in recent months are well explained as a reflection of continuing weak El Nino conditions, on top of a long-term warming trend.

Fig. 1. 1D model of global ocean temperatures compared to observations. The model is forced with the RCP6 radiative forcing scenario (increasing CO2, volcanoes, anthropogenic aerosols, etc.) and the observed history of El Nino and La Nina since the late 1800s. The observations are monthly running 3-month averages and are offset with a single bias to match the model temperatures, which are departures from assumed energy equilibrium in 1765.

2019 Alaska aerial survey found the most polar bears since 2012 – dozens of fat healthy bears

by Polar Bear Science, January 12, 2020 in WUWT

This aerial shot of six fat polar bears lolling around on a sand beach on the coast of the Southern Beaufort Sea, Alaska, was taken by NOAA employees in July 2019. It exemplifies the reality that bears in this subpopulation are currently abundant and healthy, negating the suggestion that numbers have continued to drop since 2006 because bears are starving.

The above picture of polar bear health is not an exception but the rule for all 31 bears recorded onshore last July, as the photos below from other locations testify. Those who would blame this abundance of bears on lack of sea ice in 2019 should note that ice retreated as early and as extensively in 2017 yet only 3 bears were spotted onshore. Results of a recent (2017-2018) population survey, which have not yet been made public, will of course not reflect conditions seen in 2019.

Canada’s Missing Heat: Stations Across The Country Show More Cooling Than Warming

by Kirye, January 12, 2020 in NoTricksZone

Global warming alarmists like claiming that a certain place is seeing more warming and climate change than everywhere else. Remarkably, they say that about almost everywhere, which of course makes no sense.

Today we look at Canadian temperature trends using the data from the Japan Meteorological Institute (JMA) for stations where they have data available going back to at least the mid 1990s.

First we look at December mean temperatures. What follows is a chart depicting the results of 9 stations across Canada:



Of the 9 examined stations, seven show no warming taking place at all in Canada over the past quarter century for the month of December. Data: JMA.

Despite 1990s Warming, Japan Climate Has Become More Agreeable, Less Extreme Over Past 100 Years!

by Kirye, January 9, 2020 in NoTricksZone

Though the media like to tell their audience that man-made climate change is leading to more extreme weather, the data don’t support it. In fact, one could easily argue that Japan’s climate is more agreeable today.

No trend in long-term annual precipitation

Over the past 100 years, for example, annual precipitation has not trended in an particular direction over the long term, showing rather some cyclical attributes:


Data source: Japan Meteorological Agency (JMA). 

If anything, precipitation has been rather steady for the better part of the past 2 decades, and even resembles what was observed about 60 years ago, in the 1950s.

Note how the extremes in precipitation occurred in the 1970s and 1980s when most of the climate talk was about global cooling. But overall, there’s been no trend change in precipitation in Japan.

Typhoons trending downward modestly!

Carbon Sequestration

by Red Istvan, January 10, 2020 in WUWT

As most WUWT readers know, the issue of carbon sequestration is an important but largely IPCC undiscussed ‘anthropogenic global warming’ question. I got to thinking about it again as a result of the Australian brush fires that are dramatically releasing sequestered brush carbon. And it has been years since the topic was discussed in any depth here at WUWT, insofar as I know.

A cautionary note to WUWT readers. This guest post is a high level review, rather than a typically detailed and highly referenced analytic post on some paper. It is intended mainly to guide your own further research into a fairly complex subject by providing basic concepts and keywords.


There is little doubt that combusting fossil fuel raises atmospheric CO2 in the ‘short term’ at some ‘rate’. This is provable several ways including C12/C13 isotope ratios governed by the differential photosynthetic uptake of the atomically lighter, therefore more ‘reactive’, C12. The experimental proof is simple: as fossil fuel combustion releases more photosynthetically sequestered C12, the residual atmospheric fraction of heavier (so less sequestered) C13 should decline. It does.

The relevant questions for global warming are the meanings of ‘rate’ and ‘short term’. We know the present rate from the Keeling Curve. That curve shows biological sink seasonality (mainly northern hemisphere terrestrial, because plants don’t grow in winter), and surprisingly slight acceleration—much less than the estimated rate of increase in gross CO2emissions from fossil fuel consumption. (Wiki has good illustrations and discussion.) This belies the ‘saturated sinks’ assumption in the Bern sequestration model because the simple gross/net comparison shows carbon sinks must be growing significantly.

We also know from that same Keeling curve that ‘short term’ is at least decades. But is it several centuries as all the IPCC AR5 climate models predict?

Different Carbon Sink Rates


Ocean acidification a big problem — but not for coral reef fish behavior

by Norwegian University of Science and Technology, Jan. 9, 2020 in WUWT

A three-year, comprehensive study of the effects of ocean acidification challenges previous reports that a more acidic ocean will negatively affect coral reef fish behaviour.

The study, conducted by an international coalition led by scientists from Australia and Norway, showed that coral reef fish exposed to CO2 at levels expected by the end of the century did not change their activity levels or ability to avoid predators.

“Contrary to previous studies, we have demonstrated that end-of-century CO2 levels have a negligible impact on the behaviour and sensory systems of coral reef fish,” said Timothy Clark, the lead author of the study and an associate professor at Deakin University in Australia.

Although this is good news on its own, ocean acidification and global warming remain a major problem for coral reefs, the researchers said. Ocean acidification is a problem for creatures that rely on calcium carbonate to make shells and skeletons, such as coral reef organisms, while higher ocean temperatures lead to coral bleaching and death.


False Alarm: Glacier National Park Changes ‘Gone By 2020’ Signs

by Chris White, January 9, 2020 in ClimateChangeDispatch

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.

The Climate Decade that Was: Failed Predictions, Tour De Paris, and the Gretas

by  V. Jayaraj, January 8, 2020 in WUWT

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.

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.

Greenland Ice Core CO2 Concentrations Deserve Reconsideration

by Renee Hannon, January 7, 2020, in WUWT

Ice cores datasets are important tools when reconstructing Earth’s paleoclimate. Antarctic ice core data are routinely used as proxies for past CO2 concentrations. This is because twenty years ago scientists theorized Greenland ice core CO2 data was unreliable since CO2trapped in air bubbles had potentially been altered by in-situ chemical reactions. As a result, Greenland CO2 datasets are not used in scientific studies to understand Northern and Southern hemispheres interactions and sensitivity of greenhouse gases under various climatic conditions.

This theory was put forward because Greenland CO2 data were more variable and different than Antarctic CO2 measurements located in the opposite polar region about 11,000 miles away. This article re-examines Greenland ice cores to see if they do indeed contain useful CO2 data. The theory of in-situ chemical reactions to explain a surplus and deficit of CO2, relative to Antarctic data, will be shown to be tenuous. The Greenland CO2 data demonstrates a response to the Medieval Warm Period, Little Ice Age, Dansgaard-Oeschger and other past climate change events. This response to past climate changes offers an improved explanation for why Greenland and Antarctic CO2 measurements differ. Further, Greenland CO2 measurements show rapid increases of 100 ppm during warm events in relatively short periods of time.

Atmospheric CO2 is More Variable in Northern Latitudes

Figure 1, from NOAA, shows atmospheric CO2 concentrations measured from the continuous monitoring program at four key baseline stations spanning from the South Pole to Barrow, Alaska. CO2 has risen from about 330 ppm to over 400 ppm since 1975 and is increasing at approximately 1-2+ ppm/year. Many scientists believe that rapidly increasing CO2 is mostly due to fossil fuel emissions.

Climate models continue to project too much warming

by Dr. J. Lehr & J. Taylor, January 6, 2020 in CFACT

A recently published paper, titled “Evaluating the Performance of Past Climate Model Projections,” mistakenly claims climate models have been remarkably accurate predicting future temperatures. The paper is receiving substantial media attention, but we urge caution before blindly accepting the paper’s assertions.

As an initial matter, the authors of the paper are climate modelers. Climate modelers have a vested self-interest in convincing people that climate modeling is accurate and worthy of continued government funding. The fact that the authors are climate modelers does not by itself invalidate the paper’s conclusions, but it should signal a need for careful scrutiny of the authors’ claims.

Co-author Gavin Schmidt has been one of the most prominent and outspoken persons asserting humans are creating a climate crisis and that immediate government action is needed to combat it. Again, Schmidt’s climate activism does not by itself invalidate the paper’s conclusions, but it should signal a need for careful scrutiny of the authors’ claims.

The paper examines predictions made by 17 climate models dating back to 1970. The paper asserts 14 of the 17 were remarkably accurate, with only three having predicted too much warming.

One of the paper’s key assertions is that global emissions have risen more slowly than commonly forecast, which the authors claim explains why temperatures are running colder than the models predicted. The authors compensate for this by adjusting the predicted model temperatures downward to reflect fewer-than-expected emissions. Yet fewer-than-expected greenhouse gas emissions undercut the climate crisis narrative.

The U.N. Intergovernmental Panel on Climate Change has already reduced its initial projection of 0.3 degrees Celsius of warming per decade to merely 0.2 degrees Celsius per decade. Keeping in mind that skeptics have typically predicted approximately 0.1 degree Celsius of warming per decade, the United Nations has conceded skeptics have been at least as close to the truth with their projections as the United Nations. Moreover, global temperatures are likely only rising at a pace of 0.13 degrees Celsius per decade, which is even closer to skeptic predictions.

Even after the authors adjusted the model predictions to reflect fewer-than-expected greenhouse gas emissions, there remains at least one very important problem, which immediately jumped out at us when carefully examining the paper’s findings: The paper’s assertion of remarkable model accuracy rests on a substantial temperature spike from 2015 through 2017. A strong, temporary El Niño caused the short-term spike in global temperatures from 2015 to 2017. The plotted temperature data in the paper, however, show that temperatures prior to the El Niño spike ran consistently colder than the models’ adjusted predicted temperatures. When the El Niño recedes, as they always do, temperatures will almost certainly resume running colder than the models predicted, even after adjusting for fewer-than-expected greenhouse gas emissions.

Another problem with the paper is that it utilizes controversial and dubiously adjusted temperature datasets rather than more reliable ones. The paper relies on temperature datasets that are not replicated in any real-world temperature measurements. Surface temperature measurements and measurements taken by highly precise satellite instruments show significantly less warming than the authors claim. The authors rely on temperature datasets that utilize controversial adjustments to claim more recent warming than what has actually been measured, which further undercuts their claim of remarkable model accuracy.

Contrary to what has been written in many breathless media reports, the most important takeaways from the paper are that greenhouse gas emissions are rising at a more modest pace than predicted, the modest pace of global temperature rise reflects the modest pace of rising emissions, and climate models have consistently predicted too much warming—even after accounting for fewer-than-expected greenhouse gas emissions. A temporary spike in global temperatures reflecting the recent El Niño does not save the models from their consistent inaccuracy.

The Evidence Proves That CO2 is Not a Greenhouse Gas

by Tim Ball, September 13, 2018 in Technocracy.News

The Intergovernmental Panel on Climate Change (IPCC) claim of human-caused global warming (AGW) is built on the assumption that an increase in atmospheric CO2 causes an increase in global temperature. The IPCC claim is what science calls a theory, a hypothesis, or in simple English, a speculation.  Every theory is based on a set of assumptions. The standard scientific method is to challenge the theory by trying to disprove it. Karl Popper wrote about this approach in a 1963 article, Science as Falsification. Douglas Yates said,

“No scientific theory achieves public acceptance until it has been thoroughly discredited.”

Thomas Huxley made a similar observation.

“The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, skepticism is the highest of duties; blind faith the one unpardonable sin.”

In other words, all scientists must be skeptics, which makes a mockery out of the charge that those who questioned AGW, were global warming skeptics. Michael Shermer provides a likely explanation for the effectiveness of the charge.

“Scientists are skeptics. It’s unfortunate that the word ‘skeptic’ has taken on other connotations in the culture involving nihilism and cynicism. Really, in its pure and original meaning, it’s just thoughtful inquiry.”

The scientific method was not used with the AGW theory. In fact, the exact opposite occurred, they tried to prove the theory. It is a treadmill guaranteed to make you misread, misrepresent, misuse and selectively choose data and evidence. This is precisely what the IPCC did and continued to do.

Early Holocene Temperature Oscillations Exceed Amplitude of Observed and Projected Warming in Svalbard Lakes

by Van der Bilt et al. , December 3, 2019 in GeophysResLetters


Arctic climate is uniquely sensitive to ongoing warming. The feedbacks that drive this amplified response remain insufficiently quantified and misrepresented in model scenarios of future warming. Comparison with paleotemperature reconstructions from past warm intervals can help close this gap. The Early Holocene (11.7–8.2 ka BP) is an important target because Arctic temperatures were warmer than today. This study presents centennially resolved summer temperature reconstructions from three Svalbard lakes. We show that Early Holocene temperatures fluctuated between the coldest and warmest extremes of the past 12 ka, exceeding the range of instrumental observations and future projections. Peak warmth occurred ~10 ka BP, with temperatures 7 °C warmer than today due to high radiative forcing and intensified inflow of warm Atlantic waters. Between 9.5 and 8 ka BP, temperatures dropped in response to freshwater fluxes from melting ice. Facing similar mechanisms, our findings may provide insight into the near‐future response of Arctic climate.

It has been hotter, fires have burnt larger areas

Last summer, and this summer, has been hot in Australia. But the summer of 1938-1939 was probably hotter — and back then more ferocious bushfires burnt larger areas. In rural Victoria, the summer of 1938-1939 was on average at least two degrees hotter than anything measured with equivalent equipment since, as shown in Figure 1.

Figure 1. Mean maximum summer (December, January February) temperatures as measured at Rutherglen in rural Victoria by The Australian Bureau of Meteorology for the period when mercury thermometers were used. Data unadjusted/not homogenised.

The summer of 1938-1939 was probably the hottest ever in recorded history for the states of New South Wales and Victoria. It is difficult to know for sure because the Bureau has since changed how temperatures are measured at many locations and has not provided any indication of how current electronic probes are recording relative to the earlier mercury thermometers.

Further, since 2011, the Bureau is not averaging measurements from these probes so the hottest recorded daily temperature is now a one-second spot reading from an electronic devise with a sheath of unknown thickness. In the United States similar equipment is used and the readings are averaged over five (5) minutes and then the measurement recorded.
