Official readings show no warming in US over last 15+ yrs.

Since a new, more accurate temperature gauging system was set up in the United States in 2005, official readings show that since then, absolutely no warming has occurred throughout the nation.

“Purveyors of the belief that mankind is catastrophically impacting the global climate insist it's getting warmer year by year, but a new, improved system to assess surface temperatures established in 2005 by the National Oceanic and Atmospheric Administration, NOAA, indicates otherwise,” WND reported. “In fact, the U.S. Climate Reference Network – comprised of 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states – finds there has been no warming for the past 14 years at least.”


No cause for alarmists

For decades, climate change alarmists warning the world of impending cataclysmic doom – spurred by manmade pollutant-induced global warming – have gotten the media, schools and entertainment industry on board with promoting trillion-dollar programs to “save the Earth,” but it is argued their narrative is based on faulty information.


“One of the problems in assessing global climate is that the surface temperature record is terrible – there are very few weather stations world-wide, and fewer all the time,” the Powerline Blog explained. “Seventy percent of the world is ocean, and therefore hard or impossible to measure accurately, [and] most temperatures that go into calculations of a global average are not even measured: they are interpolated – assumed temperatures based on records at other stations.”


Because asphalt and concrete in urban areas retain and radiate heat, weather station records in cities give inaccurate inflated temperature readings for general regions, as outlying rural areas with predominantly natural environments are notedly cooler.
“Even when measured, temperature records are not very reliable,” Powerline’s John Hinderaker stressed. “The U.S. is generally considered to have the best records, but surveys show that over half of our weather stations do not comply with written standards. Some are located in places that obviously will be warmer than surrounding air, e.g., next to airport runways. Many are in cities, where temperatures are artificially inflated by concentrations of people, motor vehicles, buildings, etc., and on top of all of that, the alarmists who curate weather records have systematically fiddled with them, lowering temperatures that were recorded decades ago and raising recent ones, to exaggerate the supposed phenomenon of global warming.”


Tackling the problem of inordinately high reported temperatures, the federal government set up more accurate reading centers across the mainland U.S.


“In order to address some of these problems, the National Oceanic and Atmospheric Administration (NOAA) implemented, beginning in 2005, a new surface temperature measurement system in the U.S.,” Hinderaker informed. “[The U.S. Climate Reference Network] includes 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states. NOAA selected locations that were far away from urban and land-development impacts that might artificially taint temperature readings.”


Because of the obvious disparities – and with climate alarmists relying on higher readings from urban areas – the controversy over global warming between climate change alarmists and skeptics continues to this day.


“Prior to the USCRN going online, alarmists and skeptics sparred over the accuracy of reported temperature data,” Hinderaker pointed out. “With most preexisting temperature stations located in or near urban settings that are subject to false temperature signals and create their own microclimates that change over time, government officials performed many often-controversial adjustments to the raw temperature data.”


Concerned about inflated numbers causing a mass hysteria and overwillingness to buy into expensive programs claiming to curb global warming, those challenging the validity of rising temperatures drew attention to the flawed process used to come up with the numbers used to bolster their claim.


“Skeptics of an asserted climate crisis pointed out that most of the reported warming in the United States was non-existent in the raw temperature data, but was added to the record by government officials,” Hinderaker pointed out. “The USCRN has eliminated the need to rely on – and adjust the data from – outdated temperature stations .. and so far, [data from] the USCRN show no warming.”


Goodbye warming, hello cooling …

Now that USCRB has eliminated America’s need to rely on and adjust data produced by outdated temperature stations, the exact opposite trend of what schools, media and celebrities continually warn about is happening – the climate is cooling.


“Strikingly … USCRN temperature stations show no warming since 2005, when the network went online,” Real Clear Energy (RCE) impressed. “If anything, U.S. temperatures are now slightly cooler than they were 14 years ago.”


The Heartland Institute’s Arthur B. Robinson Center for Climate and Environmental Policy Director James Taylor argues that this nation’s influencers have freely welcomed inflated temperature readings without scrutiny.


“Climate activists frequently visit or mention particular regions, states or places in the United States and claim warming impacts are evident, accelerating and unmistakable, yet how can that be when there has been no warming in the United States since at least 2005?” Taylor questioned in an RCE report. “Unfortunately, when politicians and climate activists claim they can see the impacts of climate change in a particular place, the media rarely question them on it and tend to accept the claims at face value – but the objective temperature data show no recent warming has occurred.”


Above and beyond the last decade-and-a-half, it is believed America has not heated up for 90 years.


“There is also good reason to believe U.S. temperatures have not warmed at all since the 1930s. Raw temperature readings at the preexisting stations indicate temperatures are the same now as 80 years ago,” Taylor asserted. “All of the asserted U.S. warming since 1930 is the product of the controversial adjustments made to the raw data."


In fact, it is argued that with increased autos, pavement and machinery locally inflating temperatures around centers recording data, readings should be adjusted lower – not higher.


“If anything, the raw temperature readings should be adjusted downward today relative to past temperatures (or past temperatures adjusted upward in comparison to present temperatures) rather than the other way around,” Taylor contended. “If raw temperature readings are the same today as they were 80 years ago – when there were fewer artificial factors spuriously raising temperature readings – then U.S. temperatures today may actually be cooler than they were in the early 20th century.”


Analysis from space also indicates that alarmists pushing the theory of global warming are exaggerating temperatures as they continue to insist a global crisis is at hand – using imagery of melting glaciers, drowning polar bears and rising sea levels submerging low-lying islands and coastal lands.


“The lack of warming in the United States during the past 14 years is not too different from satellite-measured global trends,” Taylor continued. “Globally, satellite instruments report temperatures have risen merely 0.15 degrees Celsius since 2005, which is less than half the pace predicted by the United Nations Intergovernmental Panel on Climate Change climate models.”


Even with satellite data accessible, climate change activists reportedly discount and avoid using such figures and utilize flawed ground readings that bolster their call to adopt and fund a green agenda.


“Climate crisis advocates attempt to dismiss the minor satellite-measured warming by utilizing ground temperature stations around the globe, which tend to have even more corrupting biases and problems than the old U.S. stations,” Heartland’s climate expert inserted. “Of course, they adjust those readings, as well. Perhaps the time has come for American officials to direct some of the billions of dollars spent each year on climate-research and climate-change programs to building and maintaining a global Climate Reference Network.”


It is argued that as scientific advancements reduce the margin of error in temperature readings, climate alarmists will have a harder time claiming the Earth is dangerously heating up and in need of projects costing tens of trillions of dollars to cool it down.


“It is becoming increasingly difficult for American politicians and climate activists to say they can see the effects of warming temperatures in the United States,” Taylor observed. “For at least the past 14 years, there have been no such warming temperatures.”

nearing minimum

nearing minimum

and a good evening sirs and madams, though sadly i've never seen a female poster on this thread
time has flown on by and another end of melt approaches
just to refresh memories, on the whole we had a hot arctic summer and records were set in many ways
arctic ice has been in record lows for good 5 weeks(or so)
and then in late august a sharp left turn
ice melting stopped and actually had ice cover increase a small bit
strange it seems, and melt did resume
just a little more strange, but it's all strange ultimately i guess

Moscow Shivers Through its Coldest Summer in Recorded History, in over 150 Years of Data

August 30, 2019 Cap Allon


Muscovites are shivering-through what will almost certainly be (with less than 2 days to go) their coldest August in recorded history. Furthermore, daily all-time low temperature records continue to fall across the Russian Federation, joining the myriad already set in 2019.
The coldest August in record-books stretching back over 150 years is currently gripping the city, with an average air temperature of just 12C (53.6F) –some 6C below the norm– being reported by themoscowtimes.com.
Moscow’s previous coldest August was way back in 1884, when the average air temperature for the month was 4C below the norm.
According to www.hmn.ru, this August in Moscow has been characterized by unusual weather in terms of not only the cold, but also of abundant rainfall and a chronic lack of sunshine.
In addition, many daily all-time low temperature records have been tumbling across Russia of late, particularly in eastern regions, with the latest being on Kolguev Island, where the low of -1.6C (29.1F) observed on August 26 comfortably busted the old record of 0.5C (32.9F) set 36 years ago (during the solar minimum of cycle 21).

Icebergs delay Southern Hemisphere future warming

UH News » Research » Icebergs delay Southern Hemisphere…


International researchers, including those at the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaiʻi at Mānoa, have quantified for the first time that icebergs breaking off from ice shelves in the Antarctic can weaken and delay the effects of global warming in the Southern Hemisphere.
“Our results demonstrate that the effect of Antarctic melting and icebergs need to be included in computer model simulations of future climate change,” said Fabian Schloesser, SOEST researcher and lead author of the study. “Climate models currently used in the sixth climate change assessment of the Intergovernmental Panel on Climate Change do not account for this process.”
While the impact of climate change is causing some of the shelf to break up, the icebergs floating away from the continent may actually help slow down warming in the Southern Hemisphere.
Added Axel Timmermann, corresponding author of the study and director of the Institute for Basic Science (IBS) Center for Climate Physics in South Korea, “Our research highlights the role of icebergs in global climate change and sea level rise. Depending on how quickly the West Antarctic ice sheet disintegrates, the iceberg effect can delay the effects of global warming in cities such as Buenos Aires and Cape Town by 10–50 years.”


Computer simulations reveal cooling effects

The research team ran a series of global warming computer simulations, which included the freshwater and cooling effects of icebergs on the ocean. The size and number of icebergs released in their model mimic the gradual retreat of the Antarctic ice sheet over a period of several hundred years.
By turning on and off the “iceberg effect” in their climate model, the researchers discovered that icebergs can significantly slow down human-induced warming in the Southern Hemisphere, impacting global winds and rainfall patterns.
With projected future shrinking of the Antarctic ice sheet, scientists expect an intensification of iceberg discharge. Icebergs can persist for years and are carried by winds and currents through the Southern Ocean until they reach warmer waters and ultimately melt. The melting process cools ocean waters like ice cubes in a water glass. Furthermore, freshwater discharge from icebergs impacts currents by lowering ocean salinity. Whether this “iceberg effect” can slow down or alter future climate change in the Southern Hemisphere has remained an open question.
The research was published in Nature Climate Change. In addition to SOEST and IBS Center researchers, others involved in the study came from Penn State University and the University of Massachusetts.
The research team plans to further quantify the interplay between ice and climate and its effect on global sea level with a new computer model that they developed.

Winter to feature 'Polar Coaster' mix of frigid temperatures, snow: Farmers' Almanac

ic

By Travis Fedschun | Fox News

Enjoy the last days of summer, because a wild ride apparently is in store this winter.


The Farmers’ Almanac is predicting that "bitterly cold winter conditions" will be in place from areas east of the Rockies all the way to the Appalachians, with the coldest outbreak of the season arriving during the final week of January and lasting through the beginning of February.
“Our extended forecast is calling for yet another freezing, frigid, and frosty winter for two-thirds of the country,” editor Peter Geiger said in a statement on the company's website.

The Farmer's Almanac said that this upcoming winter will be "filled with so many ups and downs on the thermometer, it may remind you of a 'Polar Coaster.'"

Included in this year's outlook is the prediction of free-falling, frigid temperatures from the northern Plains into the Great Lakes. The big cities in the Northeast are may also experience colder-than-normal temperatures for much of the upcoming winter.
"Only the western third of the country will see near-normal winter temperatures, which means fewer shivers for them," the publication notes.
Besides the chilly temperatures, the eastern third of the country is expected to see above-normal winter precipitation.

Farmers' Almanac: Winter will be 'teeth-chattering' cold

Get ready for a rough winter as The Farmers' Almanac is predicting a 'colder-than-normal' season from the Continental Divide on eastward, complete with 'teeth-chattering' cold arriving in mid-February in the Northeast, Great Lakes, and even into the Southeast.


"With colder-than-normal temperatures in the Northeast and above-normal precipitation expected, our outlook forewarns of not only a good amount of snow, but also a wintry mix of rain, sleet — especially along the coast," according to the Farmers Almanac.
The publication claims that 2020 will get off to a busy start in the eastern half of the country as "copious amounts" of snow, rain, sleet and ice may fall in the time frame between Jan. 4 - Jan. 7 and Jan. 12- Jan. 15, along with "strong and gusty winds."

"And for those who live northeast of the Texas Panhandle to the western Great Lakes, watch out for what could prove to be a memorable storm producing hefty snows for the Great Plains during the third week of January," the publication notes.

In other parts of the country, the winter may not be as wild.
The Pacific Northwest and Southwest are expected to be chilly but see near-normal precipitation.

That active winter will, according to the publication, cause a slow start to spring as winter lingers across the Midwest, Great Lakes, Northeast, and New England.
The Farmers’ Almanac says it bases its long-range forecast "on a mathematical and astronomical formula developed in 1818."

How a Wayward Arctic Current Could Cool the Climate in Europe

The Beaufort Gyre, a key Arctic Ocean current, is acting strangely. Scientists say it may be on the verge of discharging a huge amount of ice and cold freshwater that could kick off a period of lower temperatures in northern Europe.

By Ed Struzik • December 11, 2017

For millennia, the Beaufort Gyre — a massive wind-driven current in the Arctic Ocean — has been regulating climate and sea ice formation at the top of the world. Like a giant spinning top, the gyre corrals vast amounts of sea ice. Trapped in this clockwise swirl, the ice has historically had more time to thicken than it generally does in other parts of the Arctic Ocean, where currents such as the Trans Polar Drift transport the ice into the warmer north Atlantic more rapidly. In this way, the Beaufort Gyre — located north of Alaska and Canada’s Yukon Territory — has helped create the abundant layers of sea ice that, until recently, covered large parts of the Arctic Ocean year-round.
These days, however, something is amiss with this vital plumbing system in the Arctic, a region warming faster than any other on the planet. Thanks in part to rising air temperatures, steadily disappearing sea ice, and the annual melting of 270 billion tons of ice from Greenland’s ice cap, the gyre is no longer functioning as it has predictably done for more than a half century. And now, scientists are anticipating that a sudden change in the Beaufort Gyre could set in motion events that — in a steadily warming world — would actually lead to a temporary but significant cooling of the North Atlantic region.
During the second half of the 20th century — and, most likely, earlier — the gyre adhered to a cyclical pattern in which it would shift gears every five to seven years and temporarily spin in a counter-clockwise direction, expelling ice and freshwater into the eastern Arctic Ocean and the North Atlantic. But for more than a dozen years, this carousel of ice and, increasingly, freshwater has been spinning faster in its usual clockwise direction, all the while collecting more and more freshwater from three sources: melting sea ice, huge volumes of runoff flowing into the Arctic Ocean from Russian and North American rivers, and the relatively fresh water streaming in from the Bering Sea.



The Beaufort Gyre is a wind-driven circulation system that traps and pushes freshwater and ice around the Arctic Ocean. NSIDC/AMAP

Today, the Beaufort Gyre holds as much freshwater as all of the Great Lakes combined, and its continuing clockwise swirl is preventing this enormous volume of ice and cold, fresh water from flushing into the North Atlantic Ocean. But, scientists say, the gyre will inevitably weaken and reverse direction, and when it does it could expel a massive amount of icy fresh water into the North Atlantic. Polar oceanographer Andrey Proshutinsky of the Woods Hole Oceanographic Institution has labeled this anticipated surge of water a “ticking climate bomb,” noting that even a partial flush of that growing reservoir — a mere 5 percent — could temporarily cool the climate of Iceland and northern Europe and have a major impact on commercial fisheries in the North Atlantic.
A similar event, known as the Great Salinity Anomaly, occurred from the late 1960s into the 1970s, when a surge of water out of the Arctic Ocean freshened and cooled the top half-mile of parts of the North Atlantic. According to British oceanographer Robert R. Dickson, the Great Salinity Anomaly represented one of the most persistent and extreme variations in global ocean climate observed during the past century. The surge of ice and freshwater cooled Northern Europe dramatically and disrupted the North Atlantic food chain, which, in turn, caused a collapse of the lucrative herring fishery. Between 1951 and 2010, as many as eight of 18 exceptionally cold European winters occurred during the period of the Great Salinity Anomaly.

The gyre’s strange behavior is likely linked, at least in part, to the profound warming of the Arctic.​
Scientists studying the current state of the Beaufort Gyre say that when the wind-driven current finally becomes “unstuck” and propels freshwater into the North Atlantic, the event could possibly be more widespread and severe than the Great Salinity Anomaly.

“We’re all waiting with bated breath to see what happens when this thing stops sucking in freshwater and finally exhales,” says Alek Petty, a post-doctoral student at NASA’s Goddard Space Flight Center and the University of Maryland, who is studying the gyre.
The Beaufort Sea, home of the gyre, is one of the most inaccessible and inhospitable places on the planet. Studying the behavior of the gyre is a major logistical challenge. But for the past 15 years, an international team of scientists from the United States, Canada, Japan, and several other countries has been conducting annual summer research expeditions into the region on icebreakers. The scientists from the Beaufort Gyre Exploration Project have watched with growing interest as the gyre has continued to expand.

“Many of us expected that the high atmospheric pressure that drives those clockwise winds over the region would have temporarily weakened or reversed by now, as they seem to have done with some regularity in the past,” says Richard Krishfield, a Woods Hole oceanographer who is part of the project. “We had expected to see that happen in 2003 when we first went up. But for reasons that are not clearly understood, that hasn’t happened. The gyre has been stuck in this anticyclonic [clockwise] pattern ever since.”




An international team of scientists has been studying the Beaufort Gyre for 15 years. In 2016, the researchers (left) measured ice thickness from points around the gyre, traveling aboard the icebreaker CCGS Louis S. St. Laurent (right). NASA

The gyre’s strange behavior is likely linked, at least in part, to the profound warming of the Arctic, and it demonstrates how disruptions in one rapidly changing region of the world can affect ecosystems hundreds, even thousands, of miles away. In a recent paper, Krishfield, Proshutinsky, and other scientists suggest that frigid freshwater pouring into the north Atlantic Ocean from the rapidly melting Greenland ice sheet is forming a cap on the North Atlantic that results in stratification that prevents storm-triggering heat from the northern end of the Gulf Stream from rising to the surface. The scientists say this may be inhibiting the formation of cyclones that would cause the motion of the gyre to weaken or temporarily reverse.
If that is the case, it may mean the gyre will continue to grow and spin clockwise for years to come. That may be good news for northern Europeans and North Atlantic fishermen who would likely suffer from the freshening of the upper layer of their ocean and the ensuing dip in temperatures. But it may simply be delaying a potentially larger flush and more profound cooling event in the future.
Some scientists suggest that the Beaufort Gyre’s expansion and continuing clockwise movement may be having one beneficial consequence for marine life in the Arctic. As Arctic sea ice has disappeared — losing 40 percent of its summer extent and about two-thirds of its total volume in the last 40 years — various nations have been eyeing a potential fishing boom. That anticipated fishing bonanza would occur as retreating ice allows sunlight to strike the water, touching off phytoplankton blooms that would then nourish populations of zooplankton, fish, seals, and whales.

But Eddy Carmack — an oceanographer who recently retired from Canada’s Institute of Ocean Sciences and who has been studying the gyre longer than any other scientist — says that as long as that thick cap of freshwater over the Beaufort Gyre prevents the saltier and nutrient-rich water located below from rising and mixing with the colder and fresher surface layer, no amount of sunshine is going to support the rich underwater life. And Carmack says that even if the gyre reverses direction and expels some freshwater and sea ice, enough cold water will remain on the surface of the Beaufort Sea to inhibit plankton growth and fisheries.

No one knows what will happen in the future when a seasonally ice-free Arctic Ocean becomes increasingly exposed to the warmth of sunshine. A gradual warming of water could someday release some of that heat that is now trapped far below the surface. But for much of this century, scientists expect that melting sea ice and frigid water flowing from Arctic rivers will leave a cold, freshwater cap on the surface of the Beaufort Gyre. And, influenced by the generally westerly winds associated with the polar high-pressure system, the gyre is expected to continue to spin in the Arctic Ocean, albeit with much less ice.
The first confirmation of the Beaufort Gyre’s existence came in the 1950s when Soviet scientists conducted research in the region. Carmack first visited the gyre in 1971. At that point, the gyre had weakened and had set in motion the Great Salinity Anomaly.
It remains to be seen when the next big flush will occur and whether it will set off a “ticking climate bomb.”​
Carmack suspects that another smaller pulse of fresh Arctic water that leaked into the North Atlantic in the early 1990s — the result of the Beaufort Gyre spinning in a counter-clockwise direction — may have suppressed the recovery of the severely overharvested cod populations in Newfoundland and Labrador. That fishery has yet to rebound in any significant way.

Carmack, Woods Hole’s Krishfield, and others are not ruling out the possibility that the gyre will weaken or reverse direction sooner rather than later. In fact, research conducted by the expedition this summer suggests that a change may be coming. The volume of freshwater in the gyre had not increased since the previous summer’s expedition, and changes in atmospheric circulation suggested a possible shift to the cyclonic activity that might weaken the clockwise rotation of the gyre.

Abrupt sea level rise looms as an increasingly realistic threat. Read more.
But it remains to be seen when and whether the next big flush will occur and whether it will set off the “ticking climate bomb” that Proshutinsky has forecast.
Speaking about the possibility of a gyre-driven surge of cold water temporarily altering the climate of the North Atlantic, NASA’s Petty says, “It’s not going to be a scene from `The Day After Tomorrow,’ [the film in which the earth’s climate radically cools]. But the fact is we just don’t know. There just isn’t enough Arctic data out there to make firm predictions in a world where climate change, ocean currents, and atmospheric forces interact in complex ways.”

That was one of the wierdest hurricanes I've ever seen.

Just slowed down and basically STOPPED.

I've never seen that happen before.


I saw one article that attributed that behavior to man-made climate change. However I think it was SINO, science in name only.

ASINO - Attempted SINO ?

I think it's a little early to say that Dorian stopping cold, what that came from.

^^^ saw the same
it is thought that climate change will produce a climate with slower moving systems
less cold air in the north produces a slower polar jet
and slower upper level winds that move hurricanes along
it's a leap to hurricanes that stop dead in their tracks
still, that's what we just saw

Australia has had their first wildfires of the season - in March, sort of. (6 month difference).

Oregon had its first significant rain. No more fire season there.

Back to top
Observations of sea-ice concentration are available from satellites year-round and almost weather-independently using passive microwave radiometers at resolutions down to 5 km. Thermal infrared radiometers provide data with a resolution of 1 km but only under cloud-free conditions. We use the best of the two satellite measurements and merge thermal infrared and passive microwave sea-ice concentrations. This yields a merged sea-ice concentration product combining the gap-free spatial coverage of the passive microwave sea-ice concentration and the 1 km resolution of the thermal infrared sea-ice concentration. The benefit of the merged product is demonstrated by observations of a polynya which opened north of Greenland in February 2018. We find that the merged sea-ice concentration product resolves leads at sea-ice concentrations between 60 % and 90 %. They are not resolved by the coarser passive microwave sea-ice concentration product. The benefit of the merged product is most pronounced during the formation of the polynya. Next, the environmental conditions during the polynya event are analysed. The polynya was caused by unusual southerly winds during which the sea ice drifted northward instead of southward as usual. The daily displacement was 50 % stronger than normal. The polynya was associated with a warm-air intrusion caused by a high-pressure system over the Eurasian Arctic. Surface air temperatures were slightly below 0 ∘C and thus more than 20 ∘C higher than normal. Two estimates of thermodynamic sea-ice growth yield sea-ice thicknesses of 60 and 65 cm at the end of March in the area opened by the polynya. This differed from airborne sea-ice thickness measurements, indicating that sea-ice growth processes in the polynya are complicated by rafting and ridging. A sea-ice volume of 33 km3 was produced thermodynamically.

This differed from airborne sea-ice thickness measurements, indicating that sea-ice growth processes in the polynya are complicated by rafting and ridging. A sea-ice volume of 33 km3 was produced thermodynamically.

well, i think you nailed it
we agree, it's unusual

i'm not so sure, well maybe...
since i probably won't be around long enough to recognize climate changing we may still be in disagreement. i do believe though that weather does change and that for the climate to register a change the weather patterns must change consistently.

i haven't observed a climate shifting to warmer conditions.


check out this animation from NASA and do please notice the ice circulation pattern around the arctic. ocean currents making the ice swirl. most undoubtedly the ocean currents affect the overall conditions there and we know about ENSO, El Nino, & La Nina messing with the Atlantic and Pacific gyres affecting polar ice concentrations.

This visualization shows the age of the Arctic sea ice between 1984 and 2019. Younger sea ice, or first-year ice, is shown in a dark shade of blue while the ice that is four years old or older is shown as white. A graph displayed in the upper left corner quantifies the area covered sea ice 4 or more years old in millions of square kilometers.

This video is also available on our YouTube channel.

sorry i couldn't migrate the video to here.

we also know that the polar vortex is currently transitioning from the antarctic to the arctic, but the rotation of those winds are counter to the ice circulation in that simulation.

the vortex winds are a result of solar influence, imo, mostly turbulence in the speed and density of the arriving solar wind.

I have. I’ve watched the SEUS shift from sub-tropical to semi-arid. I’ve lived thru droughts that last 15 years or more, watched lakes shrink and creeks dry up, watched landscapers shift from the lush flowered greenery that used to be everywhere to more xeriscaping as rainfall has declined and summer has come earlier and hotter each year. Where we were in growing zone 6/7 we’re now in zone 8. Full 8-10F hotter now on average than 50 years ago, but a fraction of the rainfall.

Given the lack of cold weather this past ‘winter’ we may not have much of an apple crop this year.

What makes you decide turbulence in the solar wind is the cause of polar vortices? Genuinely curious

not the cause of the vortex, the cause of the vortex being disrupted.


...i think you're being disingenuous saying 8-10 degrees F more than what it was 50 years ago. that would be news, and it ain't, msm would be all over that.


i lived on the edge of Mohave desert for 40 years and it was consistently hot, but it hasn't been hotter there than it used to be.


see how that works?

Yeah, I see how that works: you living 40 years in a desert that hasn’t changed waves away my living nearly 70 in a region a couple thousand miles away that *has* changed.

What kind of conservative white-boy magic *IS* that?

Why the chip on your shoulder? “Disingenuous” implies I’m trying to deceive you, and I’m not trying to deceive anyone or misrepresent anything. I don’t think your experience says anything about mine.

And polar vortex disruption? Say hello to my little friend, the Equinox: south is about to lose winter and get summer, north will hopefully get some cold weather. The opposite happened six months ago and will happen again in another six. Polar vortex over the COLD POLE.

Been happening a long ol’ time, but whatever.....
