From ClimateRealism<\/a><\/p>\n\n\n\n

By Linnea Lueken<\/a><\/p>\n\n\n\n

NewScientist, a publication dedicated to popularizing science, recently published a post titled \u201cExtreme winter weather isn\u2019t down to a wavier jet stream<\/a>,\u201d reporting on a new study<\/a> that shows, the jet stream is not getting wavier in winter months due to climate change. This is true, and it has been evident for some time, but runs counter to assertions commonly made by climate alarmists.<\/p>\n\n\n\n

NewScientist writes that \u201c[i]ncreasingly erratic winter weather in the northern hemisphere isn\u2019t a result of the polar jet stream getting more wavy, according to new research . . ..\u201d<\/p>\n\n\n\n

Although the vast bulk of the article is devoted to insisting that climate change is causing worsening winter and summer weather, claims regularly debunked at Climate Realism<\/em>, the publication deserves some credit for reporting the study\u2019s results concerning the jet stream, which was, in fact, the focus of the research itself.<\/p>\n\n\n\n

The new reports findings are not actually that \u201cnew,\u201d in the sense that Climate Realism<\/em> has reported on research that came to the same conclusion several times in the past few years, here<\/a>, here<\/a>, and here<\/a>, for instance. There is copious evidence showing that not only are cold snaps not uncommon, but that the jet stream\u2019s (and more specifically, polar vortex) influence on extreme winter weather has been acknowledged since at least 1853. Years of studies looking at the frequency of and intensity of polar vortex events have found no consistent trends. As pointed out by my colleague Anthony Watts in this<\/a> post on the subject, \u201ca 2021 study in the journal Geophysical Research Letters<\/em> found no statistically significant increase in jet stream waviness or meandering in recent decades,\u201d and he explains there has never been a consensus among scientists when it comes to the issue of polar vortex\/jet stream behavior.<\/p>\n\n\n\n

The post at NewScientist goes on to explain the new study, saying \u201crecent erratic behaviour isn\u2019t out of the ordinary,\u201d and that the jet stream has been both wavier and less wavy than it is today.<\/p>\n\n\n\n

Unfortunately, that is where the NewScientist and the authors of the paper it was discussing ceased to follow the evidence. One of the study\u2019s authors reassured NewScientist that climate change is still \u201caffecting extreme weather events in all sorts of really important ways,\u201d and that the jet stream is actually becoming wavier in the summertime<\/em>, \u201cwhere it is getting slower, with bigger waves, which leads to things like big heatwaves, drought, and wildfires.\u201d<\/p>\n\n\n\n

This would be compelling if existing data backed up the claim, but, in fact, big heatwaves, drought, and wildfires have not become more frequent or severe in recent decades. Heatwaves<\/a> were much more severe in the earlier decades of the 20th<\/sup> century, and overall drought<\/a> has been declining while precipitation increases. Now that it is summer, many outlets are attempting to claim that hot weather is driven by climate change. In doing so they almost always ignore<\/a> where heat records are being set, as it is often at airports and other heat-absorbing locations, and ignore historical records that show hot summers are not unprecedented.<\/p>\n\n\n\n

Similarly, data shows that wildfires<\/a> were worse in the past with research from NASA and the European Space Agency showing that acreage lost to wildfires has declined markedly over the past few decades.<\/p>\n\n\n\n

The NewScientist, and the AGU study it references, should have quit when they were ahead. They should have published their unalarming findings about climate change\u2019s lack of an impact on the winter jet stream without then assuring people that despite their study\u2019s findings, they really are true believers and climate change is making weather worse. The latter point is refuted by real world data.<\/p>\n\n\n\n
