Climate Change Is Altering Global Air Currents (independent.co.uk)
An anonymous reader quotes a report from The Independent: One of the scientists who demonstrated conclusively that global warming was an unnatural event with the famous "hockey stick" graph is now warning that giant jetstreams which circle the planet are being altered by climate change. Jetstreams are influenced by the difference in temperatures between the Arctic and the equator. But the Arctic has been warming much faster than tropical climates -- the island of Svalbard, for example was 6.5 degrees celsius warmer last year compared to the average between 1961 and 1990. The land has also been warming faster than the sea. Both of those factors were changing the flow of these major air currents to create "extreme meanders" which were helping to cause "extreme weather events", Professor Michael Mann said. In a paper in the journal Scientific Reports, Professor Mann and other researchers wrote that evidence of the effect of climate change on the jetstreams had "only recently emerged from the background noise of natural variability." They said that projections of the effect on the jetstreams in "state-of-the-art" climate models were "mirrored" in "multiple" actual temperature measurements. The jetstream normally flows reasonably consistently around the planet, but can develop loops extending north and south. The researchers, who studied temperature records going back to 1870 as well as satellite data, said these loops could grow "very large" or even "grind to a halt" rather than moving from west to east. The effect has been most pronounced during the past 40 years, they found.
Those air currents are playing hell with my golf score!
Around the "extreme meander" and "extreme weather events."
More fabricated garbage
Thanks for the advanced warning.
You're a dynamic system. You're always changing. From alive, to dead. Get on with it.
If climate change is real, why is there no peer-reviewed research that shows it?
You are welcome on my lawn.
As the climate is always changing, and Mr. Hockey Stick says it's man doing it. how much is man doing it and how did he prove that? If climate change is accelerating because of what man is doing, how much acceleration can they account for? In what way did they come up with their numbers? Rather than telling me all about the end of days, tell me about real science and hard numbers please.
What a bullshit article. Climate change is total bullshit.
How did this story make /. news?
Maybe you can explain to us how that's going to happen.

"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
...won't believe the climate is changing or that that's bad until the Phoenix, Arizona 'Fourth of July' parade is cancelled due to a BLIZZARD, or Christmas festivities in Fargo, North Dakota have to be cancelled because of a deadly heatwave... Or maybe just until massive tornados wipe out large swaths of major American cities where they don't normally HAVE tornados!
We are currently in a period of temporary warming due to the high amount of mid-20th century solar activity. Our conditions in the current period are identical to the temporary warming known as the Medieval Warming Now just as then, global temperatures are controlled by the sun and solar activity.
We are now entering a era of minimal solar activity, identical to the Maunder Minimum which brought about the horrible period of death, disease, and famine known as the Little Ice Age. If history and science has anything to say in the matter, we should be consuming more carbon fuels, and engaging in an expansion of carbon emissions in order to stave off another ice age, another epoch frozen crops, famine, disease, and plague.
"demonstrated conclusively that global warming was an unnatural event with the famous "hockey stick" graph" Nope. That infamous and embarrassing hockey stick came from computer models which have all been demonstrated in the intervening years to be horribly wrong.
The Trumpverse knows this to be a lie shoveled by the fake news.
here's the thing. If Global Warming/Climate Science suddenly was disproven...that same research money would plow into figuring out what/how/where the science went wrong.

Make the most of this summer because it could be your last decent one: winter is coming as the planet enters the most devastating cooling period since the 65-year Maunder Minimum of the 17th and early 18th centuries.
This is the dire forecast of Professor Valentina Zharkova, a solar physicist at Northumbria University, who has based her prediction on sun spot activity – known to be a significant driver of global climate – which is currently very low and likely to get even lower during the next three solar cycles.
She has spoken about her research and her battle to get it taken seriously by the climate establishment in an interview with the Global Warming Policy Forum. You can see it in this short film.

This is an interesting question that a lot of the evangelists don't know. In interviews and debates, it's a good question to ask.
The answer is: about 1/3 of the noted increase in temperature is directly due to humans, about 1/3 is the result of natural variation, and 1/3 is unaccounted for.
Of course this is a statistical measure, sort of like trying to determine whether throwing 4 heads in a row was a fluke or an indication of a trend, but it's the best answer we have with our current understanding and datasets.
It's interesting to point out the differences between science and, for example, religion.
How does religion typically deal with sceptics and dissenters? Usually with scorn, derision, excommunication, and occasionally death. In the bible it says "shall not suffer a witch to live", and so on.
Science is the complete opposite of religion. Scientists would never ostracise, belittle, or spew hatred on sceptics, would never blackball, blackmail, or threaten other scientists, would never cause them to lose income or hold an undergraduates' opinions hostage as a condition for getting a degree.
So when you read that 97% of scientists believe in global warming, you can tell that they come to that opinion honestly, and without coercion from other scientists.
Science is completely unlike religion.

C. Convene a study to determine if the house really is on fire, and if so, if it was due to spontaneous combustion or if there's a arsonist about?
D. "Blame Liberals!"
E. Post to Facebook or instagram?
F. Call the police to report a drunk/delusional hippie running around the neighbourhood who thinks the houses are on fire?

I stole this Sig
I remember hearing that warming in the polar regions will eventually cause a salinity shift that will trigger changes to how the ocean and air currents transmit heat, which will trigger an ice age. That normally takes a bit of time (historically at least a century, IIRC), so I expect us to enter an ice age if we fail to come up with some large scale geoengineering within the next century or so. In the meantime, things are going to be a bit rocky.
However, I could be wrong and I'm happy to have experts weigh in. We could call them scientists and they could study data, and then we could use their conclusions to make policy decisions.

why isn't there more recent material published showing the proven change?
For the same reason physics journals are not filled with recent papers investigating whether falling objects move towards or away from Earth. The human contribution (established not only by the C12/C13 ratios but also by estimates of rates of fossil fuel consumption) is no longer a matter of serious dispute. The argument has moved on to issues of climate sensitivity; just what the actual effect will be on tropical storm formation &c. If you want to see the original work establishing the human fingerprint you would need to look at papers from last century, when this was still a live issue. You are better off going to the most recent IPCC summation of the science (which will link you through to original papers), which in this case would be Chapter 8 and Chapter 10 of the 2015 WG1 report of AR5.
In the meantime that link provided gives a very nice concise summary of one of the lines of evidence by which the human fingerprint was established.
I would think that ...
... you would have thanked OP for that informative link. Or were you not the AC who wanted to know how we know about the anthropogenic contribution to observed warming?

And the soil around Fukushima was always radioactive, but somehow we managed to make it worse...
I guess Michael Mann is just lucky then because all of the similar studies done since his original hockey stick graph by different researchers on different proxy data have shown the same thing as his original graph.
Nobody on slashdot believes in global warming. Pointless to post about it here. Motivated reasoning wins out every time.
Two can play your game: I've got a perfect correlation graph between the number of windmill generators, and the slowing of the global air currents, contributing to additional warming.
Your current push for Wind power is creating additional drag on the atmosphere, equivalent to new mountain ranges popping up everywhere.
It doesn't take a PhD (which incidentally I have, and in "real" science) to understand that correlation is not causation. Professor Mann, you can stick your "hockey stick" graph up your ass and smoke it.
Yes. It is. And a few million years ago it was WAY warmer than it is today.
A few million years ago, though, humans didn't want to survive on this marble.

It would just mean more money to fuel Al Gore's private jet and lavish lifestyle which currently includes a 20 bedroom, 12 bath mansion with 10 car garage in Tennessee. Additionally he also owns an oceanside villa in Malibu, and a personal ski lodge in Vail. If that weren't enough, he also has a luxury condo in South Beach! Fight global warming!
I can't really explain it, but it's at least interesting to ponder. Take a look at Climate change opinion by country.
Awareness that there is something like this is pretty much as one would expect: People in countries with a free or mostly free press and open and affordable access to the internet are way more informed about it than people in countries where information is scarce, hard to come by or government controlled. Also, the more spare time people have to waste, the more informed they claim to be.
The map on whether it's caused by humans is interesting. Why is practically all of South America convinced that humans are the source of global warming? There is also an interesting difference between Western/Middle Europe and Eastern Europe/Russia, with the former being more convinced of human caused global warming than the latter. It's not quite the divide the Iron Curtain formed, rather it seems to be more a matter between former USSR countries being less convinced than the Rest of Europe, with some noteworthy exceptions in the BeNeLux states and England. And Japan being a real puzzle, being absolutely convinced of human-caused global warming and it being a threat.
Really interesting is now, though, when you compare that map (human caused yes/no) with the last map that deals with the question whether people think that global warming is a threat. It looks like whether people consider climate change a threat is more dependent on the country having a free press than whether they think it's human made. It's also interesting that in Western Europe more people think it's a threat than people think it's caused by humans.
All in all, pretty interesting.

From a reputable source like Michael Mann, no less. Global warming is a hoax.
Oh it can be done - and if Trump was actually smart he would do it in a way that the democrats, liberals and environments would all be cheering him on right until it's too late.
1) Ban fracking. ...
2) Ban oil imports and domestic oil drilling
3) Build coal-to-oil-to-fuel conversion plants.
4) Lots of coal miners employed
5)
6) Profit... no wait the other thing, what's it called again ? Oh right, LOSSES. Massive losses.
You need to ban fracking because that's where the competition for coal in power generation is from. That still won't be enough though - you need to create a new market, the only really viable one is to coal based petrol and diesel. This can be done in a pinch - South Africa did it right throughout the 1980s to keep their cars running during the oil sanctions, but it's expensive and not very efficient (which is good for the coal miners - inefficient conversion means you need more coal), that would put all the coal miners back to work (oil riggers would be PISSED though).
And yeah, it would be the most expensive and expansive government intervention in the economy in history - and make all sorts of polution problems (not just global warming) a lot worse, which would add even more cost.
A brutal dictator could do it - a president in a democracy who has, thus far, proven completely inept at actually getting things done in politics, has no skill at whipping votes, and couldn't even get republicans to repeal Obamacare ? Nah... never gonna happen.

There have been no published studies of windmills, yet. Just notations on migratory animal deaths. There were old studies on tree plantings, saying that the trees blocked the winds from picking up the topsoil, creating more lloess locally. But not much else. Incidental reports include loss of hunting land, less game available, be loss of sleeping areas. And subaudabe thinking feelings for miles downwind.
these models are not evidence and the hockey stick graph was debunked a long time ago.
"One of the scientists who demonstrated conclusively that global warming was an unnatural event with the famous "hockey stick" graph..."
If by "demonstrated conclusively" you mean: ....then yeah, he's the guy.

correlation is not causation
It's a little more complicated than that. The underlying mechanism involves the relationship between changing zonal mean temperatures and the strength and position of maxima in the mid-latitude westerly jet. The main condition for resonance is the formation of a zonally-directed waveguide for a particular zonal wavenumber k, which depends only on the wavenumber and the shape of the zonal-mean zonal wind (U) profile. Such a waveguide is present when a mid-latitude region of positive squared meridional wavenumber l2 is bounded by latitudes both north and south where l2 vanishes, inhibiting the dispersion of wave energy and trapping excited planetary waves in the upper troposphere (300–500mb). This can occur for zonal wavenumbers k=6–81,2, with the waveguide found at the equatorward flank of the subtropical jet at latitudes around 30–45N.
Such conditions are typically associated with a profile for U characterized by two maxima in the Northern Hemisphere, i.e. a double jet latitudinal structure. In contrast to a single jet, a double jet regime associated with a profile for U is characterized by a confined sub-tropical jet with sharp edges wherein wind speeds change rapidly with latitude3. Such sharp sub-tropical jets are highly effective waveguides30,31, a central requirement for QRA (quasi-resonant amplification).
The team here has isolated a specific fingerprint in the zonal mean surface temperature profile that is associated with QRA-favorable conditions. State-of-the-art (“CMIP5”) historical climate model simulations subject to anthropogenic forcing display an increase in the projection of this fingerprint that is mirrored in multiple observational surface temperature datasets.

if man made global warming was suddenly disproven or even shown to be just minor part of some other overall effect then carbon trade market would collapse. This would be very bad news for some. (including the BBC who invested heavily via their pension scheme)
Two types of climate change: man-made climate change and natural climate change. What % of the change in air currents is caused by each?
Competence is also irrelevant if you have a prestigious name and say what someone with deep pockets wants to hear.

Additionally he also owns an oceanside villa in Malibu...
Why would he get an oceanside anything if the seas, according to him, will rise and consume it? Does that give you AGW alarmist folks any pause?
Well when the political commentator cites actual climate scientists (not the 99 out of 100 selected by climate alarmists) to back up their claims, there's a kernel of reliability present.
I'd read somewhere that the Eastern Seabord was a few meters lower than other areas and North America due to prevalent trade winds.
If the trade winds suddenly stop or reverse course, that's going to, in the short term, have a more meaningful effect than just an increase of melt water.

You've heavily discounted the value of being a crusader, savior, the first and, more importantly, *being right!* (assuming you believe your own screed).
Apparently you and I view 2-3C differently.
And just as apparently, you're discounting the fact that our ancestors *did* survive on this marble and did so well enough to become us.
We used to think it was quite warm in the medieval warm period and quite cold in the little ice age.
But then we suddenly learned the global temperature was as flat as the handle of a hockey stick.

The hockey stick graph? Please point to the Medieval Warm Period when it was 2C or so warmer than now.
The headline is just plain idiocy. It's like saying changes in global air currents are causing changes in global air currents.
Press idiots need to understand that climate change is not the same thing as global warming. Climate change is a predicted *consequence* of global warming. Global warming is an experimentally measured phenomenon. Climate change is mainly a set of predicted phenomena. Global air currents are not actually climate change, but changes in their patterns can be expected to cause climate change.
Religious zealotry clouds the mind.
Hahahaha! This is so funny! All you climate-change idiots ruining your lives by believing in this crap! Shit, my buddy believes in that crap and he had to wait 4 extra weeks for the ski-resort to open; and then he stopped skiing 3 weeks early this season as well. Plus, he missed out on the awesome ice-racing. Meanwhile, since I don't "believe" in all this climate-change bullshit I went ahead and went to the ski resorts while they were "closed," and went out ice-racing on the "not frozen enough" lakes! What an idiot he is for believing in this crap. Oh, on a side-note, anyone have some skis I can buy cheap, and a car?

I'm tired of fake news.
Since the breakup of the Polar Vortex, cold air can now sag down on North America every once in a while, following the direction change in the Jet Stream, creating havoc with the seasons. Temperatures, which were once average, will seesaw every now and then.. It won't be funny when the farmers try to plant crops and run into unseasonable weather.
Please point to your evidence that it was 2C or warmer globally in the MWP than it is now. Also Mann's original hockey stick graph started in 1400, well after the end of the MWP.

Doesn't include carbon footprint of construction. Also extended use (parties, fundraisers, etc.) possible due to larger space. What about winter heating.
Average house is also the wrong comparison. The correct would be an average sized house using all the same modern building techniques.
There are also significant health issues with houses that are too air-tight, and issues with mold, microbes and other nasties in the ventilation systems.
I could go on.
If you truly believe in AGW you have to prove it by living an ascetic lifestyle. Otherwise, if you don't actually modify your behavior as much as possible, why should I?
If your work in climate prediction lowers your company's stocks, you're out of a job regardless of how competent you are. But fudging results that raises the company's stocks has always been encouraged - until you get caught.

Carbon footprint of construction is EXACTLY equal to the construction footprint of the equivalent houses. Amazing isn't it? You do realize this wasn't new construction right? It's an existing home as evidenced by the article
“Short of tearing it down and staring anew, I don’t know how it could have been rated any higher,” said Kim Shinn of the U.S. Green Building Council, which gave the house its second-highest rating for sustainable design.
Average house is....the average. it's the only comparison that matters. 'Should compare to an avg house using all the same techniques"* we'll come back to this in a sec
Nobody said anything about 'airtight', except of course for the Bush administration fear mongering. You're just making stuff up at this point.
Back to 'living the ascetic lifestyle'. He's doing just that by living within a smaller footprint than the average person...which is exactly what the OP doubted.
You can use TERRAWATTS of energy and still be quite frugal when that energy is produced with carbon free sources. The Gores made a point to pay significantly more for their energy needs to purchase from renewable sources.
