MIAMI–A new study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science provides evidence that humans are influencing wind and weather patterns across the eastern United States and western Europe by releasing CO2 and other pollutants into Earth’s atmosphere.

In the new paper, published in the journal npj Climate and Atmospheric Science, the research team found that changes in the last 50 years to an important weather phenomenon in the North Atlantic–known as the North Atlantic Oscillation–can be traced back to human activities that impact the climate system.

“Scientists have long understood that human actions are warming the planet,” said the study’s lead author Jeremy Klavans, a UM Rosenstiel School alumnus. “However, this human-induced signal on weather patterns is much harder to identify.”

“In this study, we show that humans are influencing patterns of weather and climate over the Atlantic and that we may be able to use this information predict changes in weather and climate up to a decade in advance,” said Klavans.

The North Atlantic Oscillation, the result of fluctuations in air pressure across the Atlantic, affects weather by influencing the intensity and location of the jet stream. This oscillation has a strong effect on winter weather in Europe, Greenland, the northeastern U.S. and North Africa and the quality of crop yields and productivity of fisheries in the North Atlantic.

The researchers used multiple large climate model ensembles, compiled by researchers at the National Center for Atmospheric Research, to predict the North Atlantic Oscillation. The analysis consisted of 269 model runs, which is over 14,000 simulated model years.

The study, titled “NAO Predictability from External Forcing in the Late Twentieth Century,” was published on March 25 in the journal npj Climate and Atmospheric Science. The study’s authors include: Klavans, Amy Clement and Lisa Murphy from the UM Rosenstiel School, and Mark Cane from Columbia University’s Lamont-Doherty Earth Observatory.

The study was supported by the National Science Foundation (NSF) Climate and Large-Scale Dynamics program (grant # AGS 1735245 and AGS 1650209), NSF Paleo Perspectives on Climate Change program (grant # AGS 1703076) and NOAA’s Climate Variability and Predictability Program.

It’s models, all the way down.
I would suggest than the human influence came in writing the models, not the NAO actually behaving in the manner the models claim.

I think that programmers judge programs on how the program reflects what they think is right, which is why most valid experiments have some sort of “blinding” so one cannot unconsciously affect the outcome to favor expectations.

Don’t forget that the wind farms have a major influence by taking energy out of the wind. hence lower wind speeds.

Also remember that cities in the USA and elsewhere have built skyscrapers (which dwarf those of the previous century) and have a considerable drag on wind. Again lower wind speed.

Human actions are warming the planet, is the claim of the alarmists.

Let’s look at the AMO chart, whose temperature profile is representative of all regional surface temperature charts from around the world:

comment image

The AMO shows several warm periods of about equal magnitude. There is the highpoint in the 1880’s, the highpoint in the 1930’s, the highpoint in 1998 and the highpoint in 2016. All four of these highpoints were equally warm.

Alarmists don’t look at anything before 1979, when the satellites started recording global temperatures. They don’t look at the past because the Temperature Data Manipulators have distorted the past and artificially cooled the past to make it appear that temperatures have been getting hotter and hotter and hotter throughout the entire recorded temperature record of several hundred years.

But the AMO, and other regional charts put the lie to the data manipulation and artificial cooling of the past.

The alarmists want us to believe that we are currently experiencing unprecedented warming, but the AMO chart clearly shows this is a distortion of reality, and I would say it is a deliberate distortion of reality done to promote a political agenda.

The unprecedented warming the alarmists are trying to get people to panic over, doesn’t exist. The AMO shows this clearly. The world just went through a decades-long warming trend starting in the late 1970’s, almost identical to previous warming periods in the 1880’s and 1930’s, and now it appears we might be starting on the downhill side of the current cycle like happened from the 1880’s to the 1910’s and from the 1930’s to the 1980’s.

The Earth warms for a few decades, and then it cools for a few decades and this pattern repeats within upper and lower limits, at least since the warming began after the Little Ice Age.

There is now more CO2 in the atmosphere than there was in the 1880’s and the 1930’s, yet the temperatures are no warmer now than they were then. This shows CO2 is not the control knob for Earth’s temperatures.

Here’s a link to a NASA page where you can see a US surface temperature chart (on the left of the page) next to a bogus, bastardized, instrument-era, computer-generated Hockey Stick chart.

The US surface temperature chart (Hansen 1999) shows the same temperature profile as the AMO chart.

The bogus Hockey Stick chart shows the past temperature record has been artificially cooled into insignificance, and makes the temperature profile look like things have been getting hotter and hotter for decade after decade and shows the Earth to be at the warmest temperatures in human history.

And it is all a BIG LIE perpetrated by people with political and personal agendas. They are intent on selling the Human-caused Climate Change narrative.

But the regional surface temperature charts show the Hockey Stick is a lie.

This “hotter and hotter” lie is costing the world $Trillions of dollars in wasted spending to solve a CO2 problem that does not need solving. CO2 is a benign gas, essential for life and it is being demonized without any evidence, for political purposes.

Well, isn’t that the Blues. I tried this link out before posting it and the page came back “not found”. Perhaps NASA has decided to erase this embarrasing webpage from their computers.

You try it, and see what you get:

NASA censors their own webpage. Cowards. They can’t stand the truth, so they erase it.

Maybe the Wayback Machine has a copy.

After I saw that “not found” message (I must say I wasn’t *that* surprised to see this webpage disappear), I was looking around for a good example of a Hockey Stick I could use as an illustration, and in the process I ran across the GISS temperature values for the years 1880 to the present, and they currently show 1998 as being about 0.62C above the average for this period and show 2016 to be 1.02C above the average for this period.

The UAH satellite chart shows 1998 to be statistically tied with 2016 for the hottest year since the Early Twentieth Century, which just goes to show how much NASA Climate artificially cooled 1998 with their computers in order to sell their 21st century “hottest year evah!” meme.

The weather balloon temperature data correlates with the UAH satellite records.

Obviously, the weather balloon temperature data do not correlate with the bastardized Hockey Stick charts.

The UAH satellite chart is the only one we can trust.

The evidence is in the future. They almost made a verifiable prediction:

Once they can show this is so, it may be time to pay some attention.
Of course we will need to be wary that any correct prediction is based on something more than just being able to identify normal patterns.

Given their emphasis on the model runs and simulated years, you know their mathematical skills are nonexistent.

Why 269 model runs?
Multi Model runs?
Why the disparity of how many times each model was run?
Could it be that many of their runs were ‘inconvenient‘?

Yes, I would prefer one good, reliable model over several models with little or no skill.

Logically, there can be only one best model. Averaging its results with all the lesser-quality models just reduces the accuracy of the forecast.

“How does one identify that ‘one best model’,” you ask? By comparing past forecasts with today’s climate and weather. Validating models seems to be a novel idea that hasn’t occurred to any of the modelers!

To be fair, it would be desirable to be able to know what the future holds. It is the same reason we take the trouble to look at the weather forecasts. However, to be useful, we have to be able to trust the models, and, ideally, have some idea of what the false-positive and false-negative rates are. As it is, the credibility of Global Circulation Models is less than the credibility that Cassandra had, even though she was right.

“Sad state of affairs is that propaganda from authorities trumps logic and truth at 100 to 1.”

It’s actually a dangerous state of affairs. Dangerous enough to put a traitor and criminal and delusional idiot back in the Oval Office.

The Doomsday Clock has moved closer to disaster. Biden’s weak, possibly compromised actions, are putting the dictators of the world in an expansionist mood. They think they see some easy pickings out there in the greater world with no oppostion to speak of.

If I were a new president in this current situation I would tell the Chicoms there will be no limited nuclear war. I would tell them if they detonate a nuclear weapon in anger, that the United States will launched a full-scale nuclear attack on the Chicoms and specifically in an effort to destroy the leadership of the Chinese Communist Party. Xi won’t walk away from this one.

That ought to cause them to give up their limited nuclear war strategies. Of course, the president would have to convince the Chicoms he meant business. Biden doesn’t fit that bill. He may be subject to blackmail from the Chicoms. That’s probably a pretty good bet considering what we already know about the Biden family influence peddling.

Predicting the climate 100 years into the future is a lot like weather prediction. You start out with an initial prediction, update it annually with the expectation of changes, and finally, as the centennial date approaches, gain more confidence in the prediction — which may or may not come to pass.

As a friend of CGEP, you know how deeply energy shapes the global economy and fosters rising prosperity while at the same time contributing three-quarters of global carbon emissions. As such, energy policy solutions informed by rigorous research and dialogue are key to addressing not only the urgent threat of climate change, but the challenge of increasing access to energy to end poverty and create economic opportunity around the world.
That’s why, since its establishment, CGEP has worked to engage with diverse stakeholders to develop policy tools and inclusive, actionable solutions to address our most pressing energy and climate challenges. We’ve worked to bridge the gap between academia and policy through research, dialogue, and education, and have developed innovative new tools and programs to train the next generation of leaders and deliver research insights in formats and timeframes that are accessible and useful to decision-makers outside of academia.
Going forward, the Center on Global Energy Policy will redouble its efforts across the broad range of energy and climate change challenges that deeply impact the environment, global economy, geopolitics, equity and justice imperatives, and more. In partnership with the Climate School, CGEP will continue to serve as a model for how to apply academic knowledge to real-world solutions and impact. ”

Wow, it looks like they’ll fix everything- even things that don’t need fixing.

I almost stopped reading at this false statement “CO2 and other pollutants”. It is profoundly ignorant to call an odorless, tasteless, harmless gas that is the basis for all life on this planet a pollutant.

They get part credit for this one “Scientists have long understood that human actions are warming the planet,” because human activity has resulted in an increase in water vapor (about 90% of WV increase is from irrigation) which has contributed partly to the approximately 1.2 K of planet warming since the depths of the LIA. Their mistake is thinking CO2 contributed anything significant to climate.

The final blow came when they admitted this “researchers used multiple large climate model ensembles”. CO2 has no effect on climate. Any model that says it does is faulty.

Most (if not all) GCMs assume constant relative humidity to determine WV which is wrong but even if it was done correctly using the increase in saturation vapor pressure with temperature of the liquid water, the actual measured WV is about 43% more. Comparison of assumed with measured WV is shown in this graph. This and much more is at http://globalclimatedrivers2.blogspot.com

Noisy paper “The analysis consisted of 269 model runs, which is over 14,000 simulated model years.” https://www.nature.com/articles/s41612-021-00177-8
From the abstract
“Overall, we suggest that improving climate models’ response to external radiative forcing may help resolve the known signal-to-noise error in climate models.”
From the paper
“As exhibited by Fig. 2a, these positive values may be a matter of good luck, given the low signal-to-noise ratio in the NAO and the negative ensemble mean ACC in CSIRO-Mk3 may simply be the result of its small ensemble size (for the purposes of this problem)……[last line] Therefore, the influence of the NAO on climate around the North Atlantic basin is likely too weak in these projections. Given the predictive value that we find for the NAO in external forcing, we expect that devoting effort to the difficult and uncertain task of improving the response of climate models to external forcing will improve the signal-to-noise ratio in climate models and therefore projections and predictions of future climate. ”

OK, early models left a lot to be desired and we now know so much more about climate! Therefore, here’s my suggestion for finding the best model.

Take the latest and greatest model Mark V (and all of its competitors), and if necessary, train it for the period of the oldest reliable weather data to 1991. Then, assume it is 1991 and run it forward in time to today. Compare the decadal moving-average predictions with actual history and see which model comes closest to reality, using a least-squares difference measure.

Determine what makes the best model different from the others.

If no model does better than the nominal 3X amplification of temperature anomalies and at least gets the sign of the change in precipitation right at regional scales, then chuck them all and start over. Don’t bother using RCP-8.5 as a scenario.

At this point I think the climate change studies can be done by robots.

Direct billing to the grant account is also available. You still need biased human operators to set up the pal review and pal grant program at the agency though.

“The North Atlantic Oscillation (NAO) is predictable in climate models at near-decadal timescales. Predictive skill derives from ocean initialization, which can capture variability internal to the climate system, and from external radiative forcing.”

So they are using AMO anomalies which are driven by NAO anomalies, to predict NAO trends, that’s a fine circular reasoning project.

“Though the results here imply that external radiative forcing is a major source of predictive skill for the NAO, they also indicate that ocean initialization may be important for particular NAO events (the mid-1990s strong positive NAO)”

The NAO had a distinctly negative regime from 1995-1999, due to a decline in solar wind temperature/pressure from then, but the positive NAO regime in the early 1990’s was in fact partly influenced by the Pinatubo eruption. There is not a word either about how northeast Pacific warm blobs hold the NAO positive when the AO goes negative, like in winter 2013-2014.

I have been predicting NAO anomalies at weekly scales since 2008, they can be just as positive or negative with a warmer or a colder AMO. The Atlantic SST anomaly pattern drives atmospheric blocking patterns, it doesn’t dictate the sign of NAO trends. They have a signal-to-noise paradox because they have no idea that short term changes in the solar wind drive the NAO noise, and which is actually the most predicable component and with far more utility than their trend modeling.

Interesting. I thought heat waves and extreme cold was associated with blocking, and blocking associated with negative NAO. Here https://www.princeton.edu/news/2019/05/08/occurrence-back-back-heat-waves-likely-accelerate-climate-change they “ran climate simulations on an advanced model” an found “that as global temperatures increase, heat waves will become more frequent and the time between them will become shorter” which should mean more negative NAO. Am I wrong? Is it a matter of picking the ‘right’ model for the result one want to see?

How does this compare with record low temps in Europe (incl. recent article about Germany), USA 48 states observations, global changes (before adjustments)?
It doesn’t matter how many models are used and how many runs are done. These toy models are based on garbage in, garbage out. The more you run them, the more garbage they produce with a thin veneer of scientific justification & “looks like” it reproduces natural variability. The many models&runs averaged together hides the detail like wearing foggy glasses.
They need to improve the models so they can pick a winner and have something reliable for prediction (if that’s possible).

So lets pretend that humans are directly influencing the WX. Humans also directly influence land so rather than laying barren or sustaining weeds the land is selfishly manipulated to produce beneficial crops. Ice breakers directly influence ice accumulations so that trade made commence. Humans dig canals, construct dams, extract minerals from the ground and do all sort of things that directly influence events and the physical nature of Earth.

Only lunatics and destroyers want to characterize any human activity as cataclysmic, always assuming that every modification is an existential threat to all living beings.

So if humans are directly influencing the WX, how is it always a bad thing? And if it is axiomatic that any human change is bad, how is it that we tolerate Bill Gates and the other Malthusians who talk about filling the atmosphere with dust and smoke to lower temperatures? How are their lunatic ideas “sustaining” while those that promote human flourishing are always characterized as evil?

These yahoos actually believe they can predict NAO based upon their playing with bogus models imitating NAO data?

I suggest that they should be given access to online trading, so long as they are restricted to their own bank accounts.

CAGW is already a disconfirmed hypothesis because CAGW’s hypothetical global temp anomaly projections, and all other catastrophic predictions (ocean pH, severe weather, sea level rise, etc.,) have been so devoid from reality that the hypothesis has already surpassed the criteria necessary for official disconfirmation.

Sure, an excellent case can be made that manmade CO2 emissions have contributed to some of the beneficial global warming we’ve enjoyed since the end of the Little Ice Age in 1850, but all the catastrophic predictions not only haven’t occurred, a much better case can be made that manmade CO2 emissions have had a net positive affect for all life on earth.

Unfortunately, we’ll soon be experiencing 30+ years of global cooling from PDO & AMO ocean cycles reentering their respective 30-year cool cycles which will have a net negative impact on all life on earth..

CAGW has become a joke.

And back when the fixation was all about the comming Ice Age…

“These variations, perhaps more than any underlying trend to a
warmer or colder climate, create difficulties for the planning age in
which we live. They may be associated with the increased meridionality
of the general wind circulation, the greater frequency of blocking, of
stationary high and low pressure systems, giving prolonged northerly
winds in one longitude and southerly winds in another longitude sector
in middle latitudes.

Over both hemispheres there has been more blocking in these
years… The most remarkable feature seems to be the an intensification of
the cyclonic activity in high latitudes near 70-90N, all around the
northern polar region. And this presumably has to do with the almost
equally remarkable cooling of the Arctic since the 1950’s, which has
meant an increase in the thermal gradient between high and middle
latitudes.”

 

HH Lamb: Climate, History and the Modern World – pp 267-270

 

And it was not only Lamb.

“In 1975, CC Wallen,  Head of the Special Environmental Applications
Division of the World Meteorological Organization, had this to say about
the consequences of the cooling trend since 1940:

The principal weather change likely to accompany the cooling trend is increased variability-alternating extremes of temperature and precipitation in any given area-which would almost certainly lower average crop yields.

During cooler climatic periods the high-altitude winds are broken
up into irregular cells by weaker and more plentiful pressure centers,
causing formation of a “meridional circulation” pattern. These small,
weak cells may stagnate over vast areas for many months, bringing
unseasonably cold weather on one side and unseasonably warm weather on
the other. Droughts and floods become more frequent and may alternate
season to season, as they did last year in India.
Thus, while the hemisphere as a whole is cooler, individual areas may alternately break temperature and precipitation records at both extremes

Actually, a model is a complex hypothesis. It is part of the Scientific Method. Which means, it should be falsifiable, and to be of any value should be subjected to testing; if found wanting, it should be modified, or completely rejected if not salvageable.

The problem is that the modelers do minimal testing and the Media treat each iteration of a computer implementation as though it were Settled Science. The modelers tend to over-rate their contributions out of enthusiasm, and the Media are uncritical out of ignorance.
