Extreme Winter Weather In the US Linked To a Warming Arctic (theverge.com) 219
A new study shows how global climate change can have ripple effects at the local level. According to the research, extreme winter weather is two to four times more likely in the eastern U.S. when the Arctic is unusually warm. The Verge reports: Researchers analyzed a variety of atmospheric data in the Arctic, as well as how severe winter weather was in 12 cities across the U.S. from 1950 to 2016. Since 1990, as the Arctic has been warming up and losing ice, extreme cold snaps and heavy snow in the winter have been two to four times more frequent in the eastern U.S. and the Midwest, while in the western U.S., their frequency has decreased, according to a study published today in Nature Communications. The study, however, only shows there might be a correlation -- not a direct causal link -- between the warming Arctic and severe winters in the U.S. And it doesn't show how exactly the two are connected, so it doesn't really add much to what scientists already knew, according to several experts.
Today's study focuses on the Arctic as the main culprit for the extreme winter weather. Previous research has suggested that the warming Arctic may disrupt the polar vortex, a ring of swirling cold air circling the North Pole. Think of the polar vortex as a river, says study co-author Judah Cohen, a climatologist and director of seasonal forecasting at Atmospheric and Environmental Research. The fast flow of this river locks up the cold air over the Arctic. But as the Arctic warms -- especially in some areas like the Barents-Kara seas north of Europe and Russia -- a boulder springs up in this river, disrupting the polar vortex and allowing the freezing Arctic air to flow south, Cohen says.

They use a variety of information to estimate future weather (monthly to decade scale), and in the process, comment on how current year weather matches historical weather. They look at multi-decade trends, and point out how this season is very similar to the 1950s, etc.
The comment in last quarter's winter forecast had to do with the "polar vortex" event that is leading to the "extreme" cold snaps across the US over the last 4 years or so. There are two factors at stake here, one being the "tightness" of the high-altitude wind currents around the arctic, and a secondary "rotation" effect. Imagine that there is an oval above the arctic that oscillates short and wide, mostly centered over the pole. The boundary is like a ripple that we see as wind currents. When it is circular, cold air is trapped up by the pole, and we have mild winters in the northern continents. However, over time, the polar winds oscillate north and south, which leads to daily oscillations in weather over the winter. What we see as large temperature swings are just the wind currents oscillating past.
If the oval becomes elongated, it allows the cold air to be pulled farther south, what we call the "polar vortex" with "abnormally" colder weather than average. Cold air is pulled down from the north, then hot air is pulled up from the south, and the intersection results in more winter storms than average, depending on humidity. But that dip pattern is also not stationary, it rotates on a multi-decade-long scale. In the 1990s, the polar vortex was over Russia / East Asia, and they observed the temperature swings. The North Americans (in our short-sightedness) think that if it didn't happen here, it didn't happen. But now two decades later, the elongation has rotated over us, and suddenly we're all freaking out about catastrophic weather changes.
The forecaster's point was all of this has happened before, and all of this will happen again.

Just because something happened in the past does not mean it cannot be studied scientifically. Remember that the past is where we get literally ALL of our data for our scientific models.
To qualify, you have to be able to reliably predict, what will happen... And there, despite several decades of trying, the Climate Scientists have been no more successful than the Economists.
You may have meant that as an insult but it isn't. Economics does make testable predictions that routinely turn out to be true. They don't award Nobel Prizes in economics for luc

Paleontology could make a statement to the effect of: "We will find a fossil with such and such features".
I think that nicely shows that you have no idea what paleontologists do or how they do it.
Your argument regarding Economists is an "Appeal to Authority" fallacy
Not at all. Go read their papers because you clearly haven't. I have a graduate degree in finance and I've worked with many of the economic models you question. The models stand on their own and make perfectly valid and provable predictions. No appeal to authority needed. If you want to disprove them go right ahead. There is a Nobel prize waiting for you if you do.
Like that distinguished bunch, Climate Scientists too can explain anything, but are able to predict nothing.
Again you make fairly sweeping claims about a field of study you pretty clearly know nothing about. The climate scientists make predictions routinely and are proven to be accurate within the limitations of the model. If you think otherwise then you haven't actually examined any papers on the subject. Sure there is a lot they still don't know but that's true of every field of science. You also have to understand that it takes years for most predictions of climate models to be proven. But the evidence is there. Your failure to examine it does not make it less valid.

We've got global warming. Looking at the entire globe, we find it's warmer on the whole. Parts of it may be colder, but on the whole it's warmer.
I have no idea how you select which claim from 2000 is "the" claim. There's been lots of them, some more accurate and some less accurate. Nor why you think a single claim that turns out not to be true should be cause for disgrace. Scientists live, study, observe, and learn.

The claims to watch are the official ones of the IPCC [www.ipcc.ch], and you can see in detail what claims they're willing to make and how confident they are in them, as well as references to how they got the claims. Your cite was of a scientist who made a claim that probably looked reasonable eighteen years ago, and which was reported on in the general press. There is no apparent way to go from that claim to the process behind it, which means that it's really scientifically useless. Very likely he spoke off-the-cuff

What the head-in-sand crowd doesn't realize is that all these spring snows on the east coast that have become frequent over the past ~20 years are caused by the southward loop in the jet stream shifting eastward from its traditional position, sucking down cold arctic air at the Atlantic coast.

"all these spring snows"? Please cite them.
Changes in the amount and duration of daylight received in any day (rotational period) on the Earth are due to the Earth wobbling back and forth on its axis.
This is what causes seasons. In the Norther hemisphere, seasons work like this:
Summer Solstice - the longest day
Autumnal Equinox - equal day and night
Winter Solstice - the shortest day
Vernal Equinox - equal day and night
The Vernal Equinox typically aligns with the start of Spring in terms of temperature, plan

The ice cores don't have the resolution to show a 40-50 year lag. You have two deniertrollidiot mantras mixed up: ice core lags of 800 years and solar irradiance lags (that don't exist for half the satellite record that deniers cite to "prove" the lag exists').

This is the contorted, tortured logic by desperate believers of the Church of Global Warming to explain away record cold temperatures and winters which contradict their global warming religion. [...]
In what way are record cold temperatures in some particular spot incompatible with an increase in the planet-wide average temperature? An *average* says nothing about the highs and lows of the individual numbers!
Heck, even for a single location, you could have new records for both highs and lows and still see their yearly average go either up or down.
Your argument isn't just a logical fail, it's bad elementary school math - congratulations on making the worst argument seen in a while!
