The Winter Gatekeeper Hypothesis (VII). A summary plus Q&A

by J. Vinos and A. May, Sep 22, 2022 in ClimateEtc.

“On the other hand, I think I can safely say that nobody understands climate change.” J. Vinós, paraphrasing Richard Feynman’s words about quantum mechanics.

7.1 Introduction

This plain-language summary has been written at the request of some readers of our series of articles on the Winter Gatekeeper hypothesis:

Climate is extremely complex, and people, including scientists, have a natural tendency to look for simple explanations. The Occam’s Razor principle is a good first approach but climate change cannot have a simple answer. Over the past seven years, one of the authors of this series (JV) has been laboriously reading many thousands of scientific articles and analyzing hundreds of climate datasets trying to understand how Earth’s climate changes naturally. This is a first step to understanding the human impact on climate change. The outcome of this work is the book “Climate of the Past, Present and Future.” It is a graduate-student level academic book that discusses many controversial issues about natural climate change over the past 800,000 years. In this book, a new hypothesis on natural climate change is presented. It relates changes in the strength of the meridional (poleward) transport of energy with climatic changes that have taken place, both in the past and recently.

How Can The Globe Be Warming When Most Of The Southern Hemisphere Isn’t?

by K. Richard, Sep 22, 2022 in NoTricksZone

New research continues to document non-warming and even “robust cooling” trends for entire regions of the Southern Hemisphere in recent decades.

Land surface temperature data compilations from the Southern Hemisphere (South America, Southwestern Andes, Tasmania, New Zealand, Australia) indicate that any warming during the 20th century occurred before 1980, with no obvious net warming since (Rezsöhazy et al., 2022).

…

Sea surface temperature data from the Southeastern Indian Ocean, Tasman Sea, and Great Barrier Reef region indicate no net warming since 1982 (Chapman et al., 2022).

…

A 2021 study reported a profound cooling trend for most of Antarctica in recent decades, with amplitudes of -2.8°C for East Antarctica and -1.68°C for West Antarctica during 1979-2018.

Natural Oceanic Cycles Behind Heavy East Australia Rains, New Study Finds

by P. Gosselin, Sep 21, 2022 in WUWT/NTZ

East Australia got hit by lots of rain in February earlier this year, and the media of course blamed it all on manmade climate change.

Now a new study by Holgate et al (2022) titled “The Impact of Interacting Climate Modes on East Australian Precipitation Moisture Sources” shows East Australia’s rains are directly tied to natural oceanic patterns.

Hat-tip: EIKE.

The paper’s abstract summarizes that east Australia precipitation is driven by multiple interacting climate modes and that the El Niño–Southern Oscillation (ENSO) modifies the supply of evaporative moisture for precipitation and that this is modulated by the Indian Ocean dipole (IOD) and southern annular mode (SAM).

Press Release: Important new paper challenges IPCC’s claims about climate sensitivity

by P. Homewood, Sep 20, 2022 in NotaLotofPeopleKnowThat

London, 20 September – A new paper reduces the estimate of climate sensitivity – the amount of warming expected for a doubling of carbon dioxide concentrations – by one third. The results therefore suggest that future global warming will be much less than expected.
The paper, by independent scientist Nic Lewis, has just appeared in the journal Climate Dynamics. It is an important challenge to the official view of the Intergovernmental Panel on Climate Change (IPCC).
Lewis has critiqued a 2020 assessment of climate sensitivity by Sherwood et al., which strongly influenced the IPCC’s Sixth Assessment Report, in 2021. Lewis commented:
“It is unfortunate that Sherwood et al.’s assessment of climate sensitivity, which underpinned the UN Framework Convention on Climate Change, contained such serious errors, inconsistencies and deficiencies in its methods”.
After correcting the Sherwood et al. methods and revising key input data to reflect, primarily, more recent evidence, the central estimate for climate sensitivity comes down from 3.1°C per doubling of CO2 concentration in the original study to 2.16°C in the new paper.
This large reduction shows how sensitive climate sensitivity estimates still are to input assumptions, and that values between 1.5°C and 2°C remain quite plausible.

  • Climate sensitivity represents the long-term global temperature increase caused by a doubling of atmospheric CO2 concentration. There are different measures of climate sensitivity. Both the Sherwood and Lewis papers estimate the so-called ‘effective’ climate sensitivity, which reflects a new equilibrium state projected from centennial changes after a doubling of the CO2 concentration. This measure is considered the most relevant one for predicting climate change in the coming two centuries.
  • Climate sensitivity has always been a very important, but also highly uncertain, parameter in the climate change discourse. Earlier IPCC reports assessed its value as likely to be somewhere between 1.5°C and 4.5°C, with a best estimate of 3°C. However, prompted by the Sherwood paper, the 2021 Sixth Assessment Report moved that range upwards, to 2.5 to 4°C. Although for outsiders this might sound boring, for insiders it was a revolutionary change.
  • Lewis’s corrections and revisions lead to a likely range of 1.75 to 2.7°C, which is not only lower but is also much less uncertain than either the 2021 official IPCC assessment or the very similar Sherwood et al. estimate (2.6 to 3.9°C).
  • Nic Lewis is the lead or sole author of ten peer-reviewed papers on climate sensitivity. He was a participant in the 2015 workshop that kicked off the World Climate Research Programme project that led to the Sherwood et al. 2020 paper, but he was not a co-author of that paper.

Lewis commented:
“The substantial reduction in assessed climate sensitivity upon updating key input data suggests that the increase in the bottom of the climate sensitivity range in the IPCC Sixth Assessment Report was unjustified”.
Lewis’s paper is entitled ‘Objectively combining climate sensitivity evidence’. It can be freely downloaded here. A detailed explanatory article about the paper is available here.

Climate Emergency Not Supported by Data, Say Four Leading Italian Scientists

by C. Morrison, Sep 14, 2022 in DailySkeptic

Four leading Italian scientists have undertaken a major review of historical climate trends and concluded that declaring a ‘climate emergency’ is not supported by the data. Reviewing data from a wide range of weather phenomena, they say a ‘climate crisis’ of the kind people are becoming alarmed about “is not evident yet”. The scientists suggest that rather than burdening our children with anxiety about climate change, we should encourage them to think about issues like energy, food and health, and the challenges in each area, with a more “objective and constructive spirit” and not waste limited resources on “costly and ineffective solutions”.

During the course of their work, the scientists found that rainfall intensity and frequency is stationary in many parts of the world. Tropical hurricanes and cyclones show little change over the long term, and the same is true of U.S. tornadoes. Other meteorological categories including natural disasters, floods, droughts and ecosystem productivity show no “clear positive trend of extreme events”. Regarding ecosystems, the scientists note a considerable “greening” of global plant biomass in recent decades caused by higher levels of carbon dioxide in the atmosphere. Satellite data show “greening” trends over most of the planet, increasing food yields and pushing back deserts.

The four scientists are all highly qualified and include physics adjunct professor Gianluca Alimonti, agrometeorologist Luigi Mariani and physics professors Franco Prodi and Renato Angelo Ricci. The last two are signatories to the rapidly growing ‘World Climate Declaration’. This petition states that there is no climate emergency and calls for climate science to be more scientific. It also calls for liberation from the “naïve belief in immature climate models”. In future, it says, “climate research must give significantly more emphasis to empirical science”.

Climate Hysteria: A Mass Delusion To Demonize Carbon Dioxide

by J. Corsi, Sep 14 , 2022 in ClimateChangeDispartch

Climate hysterics like to throw around the world “denier” to castigate those who don’t get with the green agenda.

The term is deliberately intended to echo the phrase “Holocaust denier” to those anti-Semites who like to insist that the Holocaust never happened. [bold, links added]

While the comparison is obscene, it’s certainly true that the Holocaust, like the climate agenda, have something in common: They both reflect a blind fanaticism untethered to actual facts.

Climate hysterics demonize carbon dioxide (CO2) much as Hitler stereotyped Jews. They then demonize their critics as “Holocaust deniers” because the psychological link is to demonize critics of the anthropogenic theory as if they were Jew-haters.

However, the term “climate deniers” outside the context of Holocaust denial makes no sense. No rational person would deny that this planet has an atmosphere, weather, and climate.

But honestly, it is climate hysterics who hate their critics, seeing them as “evil,” greedy, hydrocarbon-burning capitalists willing to make Earth’s climate unbearably hot and dangerous for all living things.

Global models underestimate large decadal declining and rising water storage trends relative to GRACE satellite data

by B.R. Scanlon et al., Jan 22, 2018 in PNAS

Significance

We increasingly rely on global models to project impacts of humans and climate on water resources. How reliable are these models? While past model intercomparison projects focused on water fluxes, we provide here the first comprehensive comparison of land total water storage trends from seven global models to trends from Gravity Recovery and Climate Experiment (GRACE) satellites, which have been likened to giant weighing scales in the sky. The models underestimate the large decadal (2002–2014) trends in water storage relative to GRACE satellites, both decreasing trends related to human intervention and climate and increasing trends related primarily to climate variations. The poor agreement between models and GRACE underscores the challenges remaining for global models to capture human or climate impacts on global water storage trends.

Abstract

Assessing reliability of global models is critical because of increasing reliance on these models to address past and projected future climate and human stresses on global water resources. Here, we evaluate model reliability based on a comprehensive comparison of decadal trends (2002–2014) in land water storage from seven global models (WGHM, PCR-GLOBWB, GLDAS NOAH, MOSAIC, VIC, CLM, and CLSM) to trends from three Gravity Recovery and Climate Experiment (GRACE) satellite solutions in 186 river basins (∼60% of global land area). Medians of modeled basin water storage trends greatly underestimate GRACE-derived large decreasing (≤−0.5 km3/y) and increasing (≥0.5 km3/y) trends. Decreasing trends from GRACE are mostly related to human use (irrigation) and climate variations, whereas increasing trends reflect climate variations. For example, in the Amazon, GRACE estimates a large increasing trend of ∼43 km3/y, whereas most models estimate decreasing trends (−71 to 11 km3/y). Land water storage trends, summed over all basins, are positive for GRACE (∼71–82 km3/y) but negative for models (−450 to −12 km3/y), contributing opposing trends to global mean sea level change. Impacts of climate forcing on decadal land water storage trends exceed those of modeled human intervention by about a factor of 2. The model-GRACE comparison highlights potential areas of future model development, particularly simulated water storage. The inability of models to capture large decadal water storage trends based on GRACE indicates that model projections of climate and human-induced water storage changes may be underestimated.

When German Environmentalists and Putin’s Government Had a Burning Love Affair

by D. Godefridi, Sept 8, 2022 in GatestoneInstitue

  • In 2011, the German Baltic Sea Nature Conservation Foundation was established as a result of an agreement between three of Germany’s leading environmental organizations – WWF, BUND and NABU – and the company Nord Stream, which is a subsidiary of the government of Vladimir Putin.
  • These environmental organizations were, moreover, at the same time fiercely opposed to German civil nuclear power, to the exploitation of shale gas in Europe and to the import of American gas via the construction of liquefied petroleum gas terminals in Germany.
  • Those were three issues where the views of the environmental organizations were totally congruent with those of the Russian Federation. This meant betting everything on “red” — as in a casino — but in this instance, on Russian gas.
  • Right after these contractual commitments by Nord Stream AG, the environmental organizations withdrew the lawsuit they had initiated against Nord Stream…
  • The German press reported last month that, inspired by the success of the first foundation, the same State of Mecklenberg-Western Pomerania was setting up a new foundation as recently as January 2021, the Mecklenberg-Western Pomerania Foundation for Climate and Environmental Protection, this time endowed with 192 million euros from the Russian government.
Those were… issues where the views of the environmental organizations were totally congruent with those of the Russian Federation. This meant betting everything on ‘red’ — as in a casino – but in this instance, on Russian gas.

Pre-1970s ‘Global’ Sea Surface Temp Measurements Are No More Reliable Or Accurate Than Guessing

by K. Richard, Sept 8, 2022 in NoTricksZone

The accuracy of the long-term global instrumental temperature record – especially the data obtained before the 1970s – wholly rests on the assumption that sailors obtained precisely reliable temperature measurements as they pulled wooden or canvas buckets out of the water from ships at random depths, locations, and times of day. They didn’t.

It has long been known that pulling a bucket out of the water from a ship is rooted in serious error, rendering the sea surface temperature (SST) data obtained nearly useless. Ashford (1948) summarized some of the more salient reliability problems with this method of measurement.

• The initial temperature of the bucket is generally different from that of the sea.

• The water in the bucket may change its temperature before the reading is taken owing to the processes of heat exchange and evaporation.

• The initial temperature of the thermometer is generally different from that of the sample.

• The thermometer is liable to scale errors.

• Owing to thermal lag, the thermometer may take an appreciable time to indicate the true temperature of the sample.

• If the thermometer is removed from the bucket when taking the reading, it may no longer indicate the true water temperature.

• The temperature may be read incorrectly.

Arctic-Wide Glaciers And Ice Caps Were Absent Or Smaller Than Today From 10,000 To 3000 Years Ago By Kenneth Richard on 29. August 2022

by K. Richard, Aug 29, 2022 in NoTricksZone

A new study details how a much warmer climate than today led to the disappearance of glaciers and ice caps during the sub-300 ppm CO2 Early to Middle Holocene. The Arctic’s modern ice extent is among the largest of the last 10,000 years.

Glaciologists Larocca and Axford (2022) have synthesized a comprehensive record of Arctic-wide glaciers and ice caps (GICs) situated near lakes for Greenland, Alaska, Arctic Canada, Iceland, Scandinavia, Svalbard, and the Russian Arctic.

They compared the current volume and extent of GICs to past Holocene periods when they were either 1) smaller than present or 2) absent, with the latter characterizations signifying greater Arctic warmth.

..;
…

Contrary to the popular view that the modern glacier and ice cap extents are unprecedentedly small or on the verge of disappearing for the first time ever, the authors found more than half the Arctic’s GICs that exist today either did not exist or were smaller than today from 10,000 to 3400 years ago, when atmospheric CO2 ranged between 260 and 270 ppm.

Furthermore, most (“80% or more”) were smaller than today or absent from 7900 to 4500 years ago, which was the peak of this interglacial’s Arctic warmth – multiple degrees Celsius warmer than today.

The following images from the paper document the “Percent of GICs smaller or absent” for each region over the course of the last 10,000 years or more. Notice that between 80% to 100% of GICs were smaller than today or absent from about 8000 and 4000 years ago, and that even the Roman and Medieval Warm Periods had lower GICs extent than today.

The largest glacier and ice cap extent of the Holocene has been realized in the last millennium, suggesting any recession of GICs in the last few centuries is but a partial return to a former period of much greater warmth.

Northern Europe Mid Summer Hasn’t Warmed In 25 Years….Late Summer Arctic Ice Near 15-Year High!

But in terms of global warming and the so-called Arctic tipping point, i.e. a point where the Arctic sea ice melts and theoretically sets off an unstoppable chain of catastrophic events – we look at the midsummer trends of Scandinavia and Finland, and then the Arctic.

As you’ll see, there’s been signs of an Arctic tipping point over the past 15 years.

Scientists: Only 10% Of The 1984-2017 Greenhouse Gas (Longwave) Forcing Was From CO2

by K. Richard, Aug 25, 2022 in NoTricksZone

A late 2021 study finds water vapor and temperature changes accounted for 90% of the changes in clear-sky downwelling longwave or greenhouse effect forcing since the mid-1980s. CO2 forcing assumed a mere bit-player role.

The seminal Feldman et al. (2015) study concluded it takes 10 years and a 22 ppm increase in CO2 to account for just one-tenth of the total longwave or greenhouse effect forcing in recent (2000-2010) climate change trends. The remaining longwave forcing contribution is from water vapor and clouds.

Numbers — Tricky Tricky Numbers: Part 3

by Kip Hansen, Aug 25, 2022 in WUWT

…

…

Bottom Lines:

1.  To support a claim that the Earth’s Climate System is “getting hotter” one has to have a long-term time series of measurements of heat in the climate system.

2.  Current Global Mean Temperature data sets do not measure heat and thus can not supply evidence for #1.

3.  The lack of such a time-series doesn’t mean that the Earth’s climate isn’t gaining energy (heat) – it simply means we don’t have any reliable measure of it.

4.  Climate Science may have some evidence of long-term energy gain or what is commonly labelled “Earth’s Energy Budget” — energy in/energy out — but it doesn’t seem to be dominate in the ongoing climate controversy.  The latest paper shows that we can still cannot directly measure instantaneous radiative forcing.  “This fundamental metric has not been directly observed globally and previous estimates have come from models.  In part, this is because current space-based instruments cannot distinguish the instantaneous radiative forcing from the climate’s radiative response.”  It is possible that future satellite missions will be able to measure directly and accurately Earth’s incoming and outgoing energy.

Nothing Alarming: Europe Data Show No Upward Trend In Droughts And Forest Fires

by P. Gosselin, Aug 24, 2022 in NoTricksZone

German online NOVO-Argumente looks at the forest fire situation in Germany and Europe.

Currently parts of Europe are experiencing severe drought conditions and forest fires are raging in Germany. Climate activists and the mainstream are claiming it’s climate change, and it’s unprecedented.

But NOVO-Argumente looks at the historical data going back decades and finds nothing alarming.

Over the long-term average (1993 to 2019), 1035 forest fires in Germany were recorded with an average of 656 hectares affected. The amount of damage is just 1.38 million euros. Forest fires therefore cost us about as much per year as we spend every 30 minutes on subsidizing solar and wind energy.

“No evidence of an increase in forest fires”

As the following graph shows, there is no evidence of an increase in forest fires over the last 30 years in terms of number and extent. The peaks are not seen in this chart from the Federal Environmental Agency because they are in the past. In 1975, over 8000 hectares burned in Lower Saxony alone. In contrast, in the year 2021, which is not yet recorded in the graph, there were only 548 forest fires in the whole of Germany on a total area of 148 hectares.

Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies

by B. Lomborg, July 2020 in TechForecSocChange

Abstract

Climate change is real and its impacts are mostly negative, but common portrayals of devastation are unfounded. Scenarios set out under the UN Climate Panel (IPCC) show human welfare will likely increase to 450% of today’s welfare over the 21st century. Climate damages will reduce this welfare increase to 434%.

Arguments for devastation typically claim that extreme weather (like droughts, floods, wildfires, and hurricanes) is already worsening because of climate change. This is mostly misleading and inconsistent with the IPCC literature. For instance, the IPCC finds no trend for global hurricane frequency and has low confidence in attribution of changes to human activity, while the US has not seen an increase in landfalling hurricanes since 1900. Global death risk from extreme weather has declined 99% over 100 years and global costs have declined 26% over the last 28 years.

Arguments for devastation typically ignore adaptation, which will reduce vulnerability dramatically. While climate research suggests that fewer but stronger future hurricanes will increase damages, this effect will be countered by richer and more resilient societies. Global cost of hurricanes will likely decline from 0.04% of GDP today to 0.02% in 2100.

Climate-economic research shows that the total cost from untreated climate change is negative but moderate, likely equivalent to a 3.6% reduction in total GDP.

1,200 Scientists, Scholars Declare: ‘There Is No Climate Emergency’

by F. Bergman, Aug 19, 2022 in Slay

A group of almost 1200 of the world’s leading scientists and scholars has signed a document to declare that “there is no climate emergency.”

The group, led by a Nobel Prize laureate, signed the declaration that states climate science is based more on personal beliefs and political agendas than rigorous scientific facts.

The World Climate Declaration warns that climate science “should be less political, while climate policies should be more scientific.”

“Scientists should openly address uncertainties and exaggerations in their predictions of global warming, while politicians should dispassionately count the real costs as well as the imagined benefits of their policy measures,” the declaration reads.

According to a report by WND, the declaration was organized by Climate Intelligence.

DEBUNKED: Europe’s claimed ‘worst drought in 500 years’

by P. Homewood,  Aug 20, 2022  , in NotaLotofPeopleKnowThat

Roger Pielke Jr debunks Europe’s “Worst Drought in 500 Years Claim”:

 

…

Conclusion

In Western and Central Europe — basically Atlantic France all the way to Moscow, north of the Mediterranean region and south of the North Sea region — the IPCC and the underlying peer reviewed research on which it assesses has concluded that drought has not increased and, logically, that increased drought cannot be attributed to human-caused climate change. The only exception here is that the IPCC has medium confidence in an increasing trend of soil moisture deficits in some subregions, however the IPCC has low confidence that this trend can be attributed to human-caused climate change. Looking to future, at temperature changes of 2C and more, at present the IPCC does not expect the current state of scientific understandings to change. But stay tuned — that’s why we do science.

Is Global Warming The Greatest Scientific Fraud In History?

by G.K. Mitchell, Aug 19, 202 in ClimateChangeDispatch

…

In its seminal report in 1990, the U.N. IPCC stated that “at the then current rate of world emissions of CO2, the global mean temperature would likely increase by 1°C by 2025.”

This statement formed the basis for the hypothesis that anthropogenic (man-made) global warmingresulted from the increased concentration of CO2 in the Earth’s lower atmosphere resulting from man-made activities.

Central to the hypothesis was that the temperature of the lower troposphere would increase as the concentration of CO2 in the troposphere increased.

Therefore, in its 1990 report, the U.N. IPCC established a direct linkage between the concentration of CO2 in the atmosphere and the temperature of the lower troposphere.

The scientific method of inquiry has guided scientific research and investigation for over 400 years. In summary, the scientific method requires that a researcher observe a phenomenon, postulate a hypothesis for the cause of the phenomenon, and then conduct experiments or scientific investigations to falsify the hypothesis.

In adherence to the scientific method, a climate scientist who thinks that man has caused global warming should develop a complex hypothesis as follows:

  1. Global warming has occurred; that is, the temperature of the world’s oceans, landmass, and relevant atmosphere has risen during the period under investigation by a statistically significant amount.

  2. Man’s activities are responsible for the global warming that has occurred.

  3. The extent to which global warming has occurred, or is reasonably projected to occur in the future, will adversely affect life on Earth.

If any of the conjectures in the complex hypothesis above are found to be invalid, the complex hypothesis is determined to be falsified and either discarded or modified.

Europe wildfires: Are they linked to climate change?–NO!!!

by P. Homewood, Aug 15, 2022 in NotaLotofPeopleKnowThat

The BBC would like you to think so, with statements like these:

So far this year, the amount of land burnt by fires across the European Union is more than three times greater than what you would expect by the middle of July.

Almost 346,000 hectares (1,370 sq miles) of land have been recorded as burnt (as of 16 July), according to the European Forest Fire Information System (EFFIS).

Much of Western Europe has been hit by a record-breaking heatwave, which substantially increases the risk of fires….

“Heatwaves and droughts are exacerbated by climate change and are absolutely the defining factor in years with massive wildfire outbreaks, like the present one,” Dr Jones says….

“But we definitely see trends in fire weather risk because of climate change.

“The risk is higher in the Mediterranean region than the rest of Europe.”

Studies show increasing fire risk for central and southern regions of Europe over the past couple of decades.

Yet tucked away in the same article is this graph which proves all of these have no basis in fact:

Activist Scientists Have Now Officially Changed A -0.5°C Global Cooling Trend Into A Warming Trend

Back in the days when data manipulation was still strictly forbidden, scientists reported the globe cooled significantly for decades even as CO₂ concentrations increased.

The global cooling amplitude was -0.5°C from 1960-1965, and 1976 was reported to be the coldest year of any year measured since 1958 (Angell and Korshover, 1978).

Today these recorded 1960-1965 and 1958-1963 cooling trends have been fully erased and replaced with a slight warming or pause.

Apocalyptic Versus Post-Apocalyptic Climate Politics

by J. Curry, Aug 11, 2022 in WUWT

From Climate Etc.

The Inflation Reduction Act that has passed in the US Senate contains a healthy dose of funding for energy and climate initiatives.  There is much discussion as to why this bill looks like it will pass, when previous climate bills (carbon tax, carbon cap and trade) failed.

The Senate bill includes billions of dollars in tax credits and subsidies for clean energy and electric vehicles. In addition to renewable-energy funding, there is also commitment to federal oil and gas expansion, albeit with fines for excessive methane leakage. The bill includes climate resiliency funding for tribal governments and Native Hawaiians and other disadvantaged areas disproportionately impacted by pollution and climate warming. Funds are also allocated to tackle drought remediation in the West.

I’ve received requests to write on this topic, here are some bits and pieces that I’ve pulled together.  My main points:

  • Post-apocalyptic climate politics have a much better chance of succeeding than fear-driven apocalyptic climate politics
  • Energy policy should be detached from climate policy to make a robust transition to a 21st century energy system that emphasizes abundant, cheap, reliable and secure power with minimal impact on the environment (including land use).

Models, Climate Scientists Wrong Again…New Study Finds Jet Stream Strengthening, Not Weakening

by P. Gosselin,  Aug 9, 2022 in NoTricksZone

Alarmist climate research centers like the Potsdam Institute and the unquestioning media have been claiming for years that the Jet Stream is weakening, hence this would lead to greater weather extremes across the northern hemisphere due to blocking. Responsible for this of course is man-made global warming.

Hat-tip: The Klimaschau

But a recent paper by Samantha Hallam et al published in the journal Climate Dynamics looks at the seasonal to decadal variations in Northern Hemisphere jet stream latitude and speed over land for the period 1871–2011. The authors were unable to find any weakening of the sort climate alarmists have been warning about.

Quite to the contrary, the authors in fact found that the winter jet stream over the North Atlantic and Eurasia has increased in average speed by 8% to 132 mph. The authors found the 141-year trends in jet latitude and speed show differences on a regional basis and that jet speed shows significant increases evident in winter (up to 4.7 ms −1 ), spring and autumn over the North Atlantic, Eurasia and North America. Over the North Pacific, no increase was observed.

…

…

Moreover, the Jet Stream was found to have shifted northward by some 330 kilometers. Overall, the paper’s findings contradict the claims of a weakening Jet Stream regularly made by the climate alarmists and their media minions.

Applying climate alarmist science, we’d have to conclude now, due to the strengthening Jet Stream, less weather extremes should be expected. This would be good news of course. But don’t expect the fear-porn media to look at this.
