This is a non political response Climate Models Models, Climate Scientists Wrong Again…New Study Finds Jet Stream Strengthening, Not Weakening By P Gosselin 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. Source: Figure 9, Climate Dynamics. 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.

Recap: The changing jet stream and global cooling Cap Allon Electroverse Wed, 11 Nov 2020 08:18 UTC 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. 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. This forcing FULLY explains why some far-northern latitudes (such as parts of Siberia) have been experiencing pockets of anomalous heat of late, while the lower-latitudes have been dealing with " blobs" of record cold. It's a phenomenon long-predicted by those studying the Sun, and one forecast to intensify as the Grand Solar Minimum continues its deepening. Let's note all the recent hysteria regarding the anomalous warmth lingering over Siberia. Well, the region's cold temperatures didn't simply up and vanish, nor had they been heated by the magic CO2 affect, or escaped Earth's atmosphere and leaked into space — no, they were diverted south on the back of a meridional (wavy) jet stream flow: and it is THIS that's the main reason for the lower latitudes experiencing record low temperatures of late. Residing to the south of Siberia is Mongolia, Kazakhstan, and little town called China. While Siberia was reportedly melting into oblivion, these regions beneath it were experiencing anomalous, often record-breaking COLD. And then in June, the Siberian Times reported that a "swing" had now occurred, that northern Siberia's well-documented heat had been followed-up by unprecedented "June snow, tornadoes and floods" — an update the MSM failed to report on. Furthermore, and serving as another example of the Changing Jet Stream, the ST article goes on to explain that while snow in the northern mountains melted some two-weeks ahead of schedule this year, "further south, though, several roads in Khakassia -known to locals as 'Warm Siberia' for its mild climate- were blocked by snow." Rare June snow in in Khakassia aka ‘Warm Siberia’. North America is another example. Because while parts of far-northern Alaska/Canada were experiencing anomalous heat back in May, the lower-latitudes beneath them -where the majority of us humans reside- were busy breaking records for all-time COLD: North America has set 233 new all-time Monthly Low Temperature Records in May (so far) vs just the 18 Record Highs Earth's climate is changing alright, there's little doubt about that. But it's the Sun that's the driving force, not Man and his irrelevant CO2-excretions. We've known the mechanisms outline above for decades, as the the below article from 1975's Science Mag would indicate, but as they clash with the modern politicized AGW agenda they've conveniently been forgotten: The COLD TIMES are returning, the mid-latitudes are REFREEZING in line with historically low solar activity, cloud-nucleating Cosmic Rays, and a meridional jet stream flow. 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. Don't fall for bogus, warm-mongering political agendas — our future is COLD as the Sun continues its descent into its next Grand Solar Minimum cycle. Prepare accordingly — learn the facts, relocate if need be, and grow your own.

"Back to Earth. There is some evidence that the Polar and North Atlantic jet streams are less stable now than they were several decades ago; weather extremes seem to be more frequent. Data from a study of tree ring records covering the last 300 years, has been interpreted as indicating greater variability in the North Atlantic Jet (primarily an increase in the sinuous shape of jet stream meanders) that coincides with extremes of heat, drought and wild fires in various parts of Europe. These kinds of extremes are not unlike those currently witnessed in north polar regions. Whether such changes are part of a longer-term trend in weather extremes, as predicted by some climate models, is still uncertain from a scientific perspective. More analyses of the tree-ring kind are required to improve the level of confidence in explaining past and present climate conditions. Watching the trends in polar temperatures, jet stream loci, and the associated weather anomalies will be interesting." geological-digressions.com
