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.
|It warms in the summer? Who knew... I grew up on a snow-capped mountain out west. Had skiing all year. Summers, the snow was a little weak, and the resorts put in artificial snow machines to make up for it, as needed. It wasn't bare rock, just not fresh clean snow, for a better experience.|
Wouldn't the world kind of get boring, stagnant, if every day was ideal, and perfect? It's the variance, and unpredictable nature, that keeps life interesting, challenging.

You don't have any data that "show" this. Why do you lie and pretend that you do?

Günther Aigner sounds like a moron, but who is the greater moron? The moron who looks for causality amidst random data or the moron who readily believes whatever conclusions he is told by the first moron?

There is no such thing as a "trend" in random events. There can be no temperature trends any more than there are trends in random coin flips.

You are lying. You do not know this. Nobody knows this. You are a liar.

Nope. Nobody has reviewed any data that has shown any sort of temperature change to within any usable margin of error. Your statement is pure disinformation. You are a liar.

I'll be the judge of that. Where's the data? What is the margin of error? Show me the raw data.
|There is snow in the alps and people go skiing.It was all predicted to be melted and it is not.can we know that?|
duncan61 wrote:It was all predicted to be melted and it is not.
Your first clue should have been your sheer reliance on the passive voice. Who did this predicting and why should anyone care?
Secondly, it wasn't predicted if it didn't happen. It was speculated. Anyone can speculate about anything. Why should anyone care about this particular failed speculation?
Any information you could provide to these question would go a long way to transform your original waste of bandwidth into perhaps interesting, maybe even useful, information.
|Perhaps there are organisations that wish to build more ski resorts however are concerned there will be no snow in the future.There will be snow for a long time in the alps.|

Alpine tundra releases long-frozen CO2 to the atmosphere, exacerbating climate warming
UNIVERSITY OF COLORADO AT BOULDER
Thawing permafrost in high-altitude mountain ecosystems may be a stealthy, underexplored contributor to atmospheric carbon dioxide emissions, new University of Colorado Boulder research shows.
The new findings, published today in the journal Nature Communications, show that alpine tundra in Colorado's Front Range emits more CO2 than it captures annually, potentially creating a feedback loop that could increase climate warming and lead to even more CO2 emissions in the future.
A similar phenomenon exists in the Arctic, where research in recent decades has shown that melting permafrost is unearthing long-frozen tundra soil and releasing CO2 reserves that had been buried for centuries.
"We wondered if the same thing could be happening in alpine terrain," said John Knowles, lead author of the new study and a former doctoral student in CU Boulder's Department of Geography and a researcher at the Institute of Arctic and Alpine Research (INSTAAR). "This study is a strong indication that that is indeed the case."
Forests have long been considered vital carbon 'sinks,' sequestering more carbon than they produce and helping to mitigate global CO2 levels. As part of the Earth's carbon cycle, trees and other vegetation absorb CO2 via photosynthesis while microbes (which decompose soil nutrients and organic material) emit it back to the atmosphere via respiration, just as humans release CO2 with every breath.
Melting permafrost, however, changes that equation. As previously frozen tundra soil thaws and becomes exposed for the first time in years, its nutrients become freshly available for microbes to consume. And unlike plants, which go dormant in winter, microscopic organisms can feast all year long if environmental conditions are right.
To study this effect in alpine conditions, researchers measured the surface-to-air CO2 transfer over seven consecutive years (2008-2014) at the Niwot Ridge Long Term Ecological Research (LTER) site in Colorado, a high-altitude research project funded by the National Science Foundation that has been in continuous operation for over 35 years. The team also collected samples of soil CO2 and used radiocarbon dating to estimate how long the carbon forming that CO2 had been present in the landscape.
The study showed, somewhat surprisingly, that barren, wind-scoured tundra landscapes above 11,000 feet emitted more CO2 than they captured each year, and that a fraction of that CO2 was relatively old during the winter, the first such finding of its kind in temperate latitudes. The findings suggest higher-than-expected year-round microbial activity, even in the absence of a deep insulating snowpack.
"Microbes need it to be not too cold and not too dry, they need liquid water," said Knowles, now a researcher at the University of Arizona. "The surprise here is that we show winter microbial activity persisting in permafrost areas that don't collect much insulating snowpack due to wind stripping it away."
While the alpine tundra's net CO2 contributions are small compared to a forest's sequestration capability, the newly-documented effect may act as something of a counterweight, hampering atmospheric CO2 reductions from mountain ecosystems in general. The findings will need to be factored in to future projections of global warming, Knowles said.
"Until now, little was known about how alpine tundra behaved with regard to this balance, and especially how it could continue emitting CO2 year after year" Knowles said. "But now, we have evidence that climate change or another disturbance may be liberating decades-to-centuries-old carbon from this landscape."

Why did you mention Günther Aigner and his statistically invalid gibberish? Why did you highlight his illogical ravings?
