The temperature data from 12 mountain stations in the European Alps show no winter warming in over 30 years, contradicting alarmist claims.
Austrian researcher skeptic Günther Aigner examined 12 mountains stations across the Alps, spanning Switzerland, Germany and Austria, in order to find out how winter temperatures have developed over the past 50 years.
“Slight increase of only 0.7°C”…”not statistically significant.”
With an Arnold Schwarzenegger accent, Aigner presents his results for the first time in English:
Winter temperature trends are of great importance for the Alps multi-billion dollar ski industry and so reliable data are crucial for planning for the future.
According to global warming alarmists, skiing in the Alps should have fried away by now, and the Arctic ice-free in the summertime. But they haven’t – and Aigner explains why.
Winter temperature dropped from early 1990s to 2010
Looking at the very reliable winter data available from the Swiss, German and Austrian meteorological services, which were diligently recorded at these stations, they show only a modest amount of warming since 1971.
Shown are the winter temperature mean anomalies for the 12 mountain stations. The green curve is the 10-year running average, the white dashed line is the linear trendline.
Reality versus public perception
“There’s an astonishing contrast between official measurements and public opinion,” says Aigner. “The linear trend shows a slight increase of only 0.7°C – which is not statistically significant.”
No winter rise in 30 years
And if we do not include the cold period of the 1970s, there’s been no warming over the past 30 years. As Aigner points out, the winter mean temperature for the 12 mountain stations fell some 2°C from about 1992 to 2011.
So it can’t be just CO2 running the show.
In the end, Aigner implies no one really needs to worry about skiing ending in the Alps anytime soon. The warming that the Alps have seen over the recent decades has happened mostly in the summer and spring months, the video reminds.
Fifty years is a nice round number of years to take, but visually at least the temperature appears cyclical from the graph. The trend line seems to cover an incomplete number of cycles and as it starts at the beginning of a cold cycle and ends in a warm one it isn’t surprising that it shows warming. It doesn’t show that the longer term trend is the same at all, does it?
“It doesn’t show that the longer term trend is the same at all, does it?”
No, it sure doesn’t. All that gives is a little snapshot in time. It does not give the full picture of the etire climate cycle, which warms for a few decades and then cools for a few decades and show nothing unprecedented is happening with the Earth’s climate and weather.
The global temperature has cooled by 0.7C since 2016, so where is all this warming alarmists keep referring to? They imply warming is ongoing, but it’s not.
A rise of 0.7°C over 50 years is warming at the rate of 0.14°C / decade. Compare this with global temperatures over the same period, warming at a rate of 0.19°C / decade. If the warming in the Winter Alps is not statistically significant it must also not be statistically different than the global average rise.
In fact there’s as much chance that the true rate of warming is 0.28°C / decade as there is that it’s 0°C.
There isn’t 50 years of reliable unadjusted real data.
So you point is left with the rest of the luggage.. in the wrong room.
You do know the late 1970s was the period of the “Global Cooling” scare, don’t you.
You do know that temperatures were warmer during the MWP, and there were less Swiss glaciers.. don’t you.
Manifest your ignorance bellhop !!
“There isn’t 50 years of reliable unadjusted real data.”
Yet this post is presenting data which fails to show a significant difference with the global data. Almost as if looking at a small part of the world, for a single season, isn’t a useful way of determining global trends.
Last time you said there was a pristine surface data set that matches UAH.

I’m still interested in what you think this is.
“You do know the late 1970s was the period of the “Global Cooling” scare, don’t you.”
It was also the period when scientists were warning about the likelihood of warming caused by rising CO2. I’m not sure what relevance any of this has to the point I was making. This article chose to start the trend of Alpine Winter temperatures in the 1970s.
Blind men groping an elephant. All that matters is the tidal gauges and they show nothing. That is that.
0.7 C warming since the 70s, and flat since 1999 is pretty much the global picture though.
I would like to see how their summer temps have changed.
But yeah, it means a ski station loses the bottom 100 meters off its runs.
I believe I have read that the continental U.S. also has no meaningful warming since more or less mid-20thcentury. So I wonder and I ask, if we made an effort to perform a regional analysis across the entire globe, where is the warming? I’m pretty sure the Arctic would stand out( if that data is accurate across time). How do other isolated areas measure up. I see no “climate crisis” anywhere. I live in Western Canada. It is certainly a little warmer than when I was a kid in the 60’s. But we grow a lot of food here and we have had excellent growing conditions for the last 20 years at least. No killer frosts in late spring or early fall that wrecked crops often when I was young.
This shows the world’s glaciers are melting – and melting now more rapidly.
this therefore is NOT any ‘rebound’ from the little ice age, not just progression from the end of the ice age, but demonstrably an effect of warming which is getting more severe.

And right on cue our resident screeching lie spewer arrives to screechingly spew lies yet again, and linking guardian is just gravy on top.
I posted elsewhere on this. As a kid in the 60’s my family took a trip through the Rockies and went by the Columbia Icefield in Alberta. The Parks Service had tourist info set up at the foot of a massive glacier with photos showing the retreat of the glacier at intervals since the 1850’s. We had a “Little Ice Age”, inconvenient though that fact may be for the worshippers of the CO2 sky God. This paper is typical climate “science” B.S. cherry-picking. Ignore everything that doesn’t support the Lefty,, Eco-Nazi narrative. The Guardian has the same relationship with the truth that Pravda had. No wonder, Commie rag.
When is the Guardian moving its offices to Antarctica? It’s obviously way too hot in Manchester or wherever by now. I here ALL the glaciers are gone there. How can people survive?
Winter temperature is not the only factor affecting ski resorts–it also has a lot to do with humidity, the path of the jet stream, and location of anticyclones.
During the winter, the Alps are along the contrast between cool, wet weather blowing off the Atlantic and relatively mild weather over the Mediterranean, with the Azores anticyclone (high pressure area) usually parked off the west coast of Africa, keeping the Sahara dry.
During some winters, the jet stream flows over northern Europe, from England to southern Scandinavia, bringing a long parade of storms with very wet weather over France and Germany, with the winds mostly out of the west to southwest. In such a winter, the weather is wet but relatively mild over northern Europe, with abundant snowfall in the Alps, but not exceptionally cold.
From time to time, the Azores anticyclone expands north and east to cover most of western Europe, bringing dry weather and light winds, with mild and dry weather in the Alps.
There’s also the possibility of a cold anticyclone moving in from Greenland, Scandinavia, or sometimes even from Russia, which brings cold, dry weather to northern Europe and the northern Alps, and turbulent weather over the Mediterranean and southern Alps. This occurred during the Olympics in Lillehammer, Norway, which led some athletes to collapse in the extreme cold, despite abundant sunshine.
The first pattern above leads to abundant snowfall in the Alps, but rather average temperatures. Both the second and third patterns above lead to below-average snowfall, the second with above-average temperatures, the third with below-average temperatures.
I’m troubled that the green line doesn’t seem to be a good match to the data.
I skied in the Alps the winters of 86-87, 87-88, and 88-89.
The winter of 86-87 was the weakest. That year I went through ski instructor training. Started out in October on a Glacier in Austria for evaluation. Next to the Zugspitz to attend the German military ski instructor course. Then doing instructing on the Braunic. And finally in March attending the Italian Incasouris (their SF) ski training and winter warfare exercise at Vipitaino in Sud Tirol. That year started slow but got better quickly. I didn’t go more than two days without skiing tha whole period.
The next winter 87-88 was outstanding. Powder up to my waist on the Braunic.
88-89 was very good for snow. That year my team got caught above the tree line on the Zugspitz in the worst winter storm to hit Bavaria in 10 years.
The amount of snow fall in a given winter does not directly coorespond to how cold it gets.
