The impact of global warming on individual weather patterns is at the very limit of science — this is the mainstream position.
“It’s kind of like having a jigsaw but most of the pieces are missing,” said Dr Andrew King from the ARC Centre of Excellence for Climate Extremes at The University of Melbourne.
“We have really incomplete observations in many parts of the world and they don’t go back long enough in time to really track the climate for long enough.”
That missing data –often from remote places like the Arctic– is needed to build computer models of unprecedented detail that can better predict weather patterns, said Dr. King.
“We really need high-resolution simulations … But we just don’t have enough data to really make conclusive statements.”
Wavy Jet Stream Theory
There are belts of high-altitude wind that encircle the globe, called the jet stream, and weather systems often follow these tracks, explained Dr King — these winds are related to temperature differences between the cold polar regions and the warm tropics.
If the world is indeed warming, as is the alarmist claim, and if the warming is indeed more pronounced over the higher latitudes versus the equator, as is detailed in the “Polar Amplification” theory, then that reduced temperature difference between the poles and the lower latitudes should “reduce the strength of the jet stream … and you might make it wavier or slower,” said Dr King.
A slower, wavier jet stream may allow storms to stick around longer, leading to more extreme weather; but there is no conclusive evidence that the jet stream is slowing due to anthropogenic global warming.
“There are a variety of studies looking into this, some of which find evidence to suggest this is happening –particularly from the model-based studies– [and] others which suggest this isn’t happening,” Dr King said.
One recent study used detailed computer modelling to show how a warmer world would lead not only to more intense rain in Europe but also to slower storm movement; however, its lead author –Abdullah Kahraman, from Newcastle University in the UK– was at pains to qualify the limits of the study, saying it related to one very detailed computer simulation.
“This study does not really tell you that this will definitely be happening like that, because this is one scenario,” Dr Kahraman reluctantly admitted, illustrating the issue with climate models: the majority are pure fantasy.
Theories are abounding…
…but there isn’t anything like the ‘consensus’ the MSM would have you believe.
“It’s basically an area of very active research, there are quite a few people around the world looking into this. And there is a diversity of views among scientists,” Dr King said.
“At the very least, I think we can say that we don’t have a great deal of confidence that this is a clear effect of climate change.
“But there is some indication that there might be more persistence of weather systems, as the jet stream may be allowing them to remain in place for longer.
“This could be contributing to some extreme weather events,” Dr King concluded.
The missing link: the Sun
Studying the jet stream has long been an indicator of the weather to come, and to study the jet stream attention must turn to the sun.
When solar activity is HIGH, the jet stream is tight and stable and follows somewhat of a straight path.
But when solar activity is LOW, that meandering band of air flowing 6 miles above our heads becomes weak and wavy, it effectively buckles which diverts frigid Polar air to atypically low latitudes and replaces it with warmer tropical air.
Scientifically, the jet stream reverts from a Zonal Flow to a Meridional Flow and, depending on which side of the jet stream you’re on, you’re either in for a spell of unseasonably cold or hot weather and/or a period of unusually dry or wet conditions.
Activity on the sun has been historically low in recent years.
The solar cycle just gone (SC24) turned out to be the weakest of the past 100+ years:
Reduced solar output –and reduced solar output alone– is behind the climatic changes we’re currently witnessing, which range from increasing polar outbreaks; an influx of cloud-nucleating cosmic rays; and an uptick in ‘sun-shading’ volcanic eruptions — increasing carbon dioxide emissions have nothing to do with the climate.

“Polar Amplification” doesn’t stack up
And finally, if AGW/Polar Amplification is indeed a thing, then why aren’t its impacts being felt in Antarctica?
Modern climate science states that “because the Earth’s polar regions are warming more quickly than the rest of the world, the temperature contrast that drives jet streams has decreased” which makes for a weak and wavy jet stream flow.
According to the AGW ‘Polar Amplification’ theory (touched-on above by Dr King), Antarctica should be mirroring the trends seen in the Arctic — i.e., warming global temperatures should be melting sea ice exposing the darker sea beneath, absorbing the heat and increasing temperatures.
But this simply isn’t happening, and yet polar outbreaks in the southern hemisphere are also on the increase (as they are in the Arctic), meaning that a different forcing must be at play here — rising temperatures cannot be blamed for the observed weakening of the jet streams, at least not globally, as the Antarctic continent is actually cooling.
The AGW theory is junk, whichever way you look at it.
The predominate forcing behind these wavier/slower jet streams is, was, and always will be low solar activity.
The COLD TIMES are returning, the mid-latitudes are REFREEZING, in line with the great conjunction, historically low solar activity, cloud-nucleating Cosmic Rays, and a meridional jet stream flow (among other forcings).
Both NOAA and NASA appear to agree, if you read between the lines, with NOAA saying we’re entering a ‘full-blown’ Grand Solar Minimum in the late-2020s, and NASA seeing this upcoming solar cycle (25) as “the weakest of the past 200 years”, with the agency correlating previous solar shutdowns to prolonged periods of global cooling here.
Furthermore, we can’t ignore the slew of new scientific papers stating the immense impact The Beaufort Gyre could have on the Gulf Stream, and therefore the climate overall.
Prepare accordingly— learn the facts, relocate if need be, and grow your own.
