Protect the mountain! Skiing and global warming?




by canares » 05/01/09, 14:32

For all fans of skiing or any other sport of sliding in the mountains, it is necessary to seriously think to worry. If we continue at this rate there in a few years winter sports will be a distant memory.

I know it's not really new but it seems that some stations are trying to make things happen

Do not confuse global warming and global warming ... short: climate change does not rhyme with global warming! Still a lot of lack of analysis in this article ... :| and predict a + 2 ° C in 17 years ca would seem very presumptuous! A good example is the high level of snow cover of the current winter ...

Nothing says that in case of a global warming it will be warmer here ... on the contrary it could be much less warm! Cf the disruption of the Gulf Stream (among others) ... https://www.econologie.com/forums/le-petit-a ... t2702.html

Here is an ecological assessment of winter sports by the Mountain Riders quoted in the article: https://www.econologie.com/the-mountain- ... -3775.html

An article of the day about this: http://www.novethic.fr/novethic/ecologi ... 136211.jsp

What future for ski resorts in the age of climate change?

Initiatives to mitigate GHG emissions are on the rise in mountain resorts. However, some associations would also like the stations to reflect in depth on adaptation to climate change. An issue that becomes crucial as snow, the focal point of the economic model, is threatened.

Since the beginning of the 2000 years, sustainable development initiatives have flourished in the mountains. The ANMSM (National Association of Mayors of Mountain Resorts) has launched from 2007 a sustainable development charter with ADEME and the Mountain Riders association. Signed by fifty stations, it contains a diagnosis and a concerted action plan by commune. As for the eco-guide launched by Mountain Riders, it lists the good practices of each station (environmental awareness, sorting of waste, access to public transport, etc.) on seven major themes (transport, energy, waste, social , territories, development and water) through the attribution of pictograms.

But, based on continuous improvement, these approaches are sometimes criticized for their tendency to greenwashing. "In the area of ​​wastewater, we incentivize those who deal with it rather than pointing fingers at those who do not, even though it is a regulatory obligation," says Vincent Neirinck of the association Mountain Wilderness. Thus, the 2012 guide states that "66% of the stations treat their effluents appropriately, have a properly designed and functioning wastewater treatment plant".

Growing mitigation policies

However, the sector is changing. Last year, 10 ski resorts published their first carbon footprint in partnership with ADEME, ANMSM and Mountain Riders. And contrary to conventional wisdom, it is not the ski lifts and artificial snow that emit the most. The main item of greenhouse gas emissions (57%) is passenger transport, far ahead of activities related to the practice of skiing which represent only 2% of emissions. An essential fact before the creation of a label that sticks to the stakes of the stations, as hopes to be the project "Flocon vert" launched this winter by Mountain Riders. "We will not simply rely on positive initiatives. The requirements will be raised one notch. They will be evaluated and quantified by a certifying body in order to demarcate certain stations and serve as a guide for the others, "explains Camille Rey-Gorrez of Mountain Riders. A real step forward? While the initiative is welcomed, stakeholders remain rather cautious about its implementation planned for 2014. "We want to move forward with a sustained and voluntary method rather than setting the bar too high, which would give an alibi to some to do nothing," explains Guy Vaxelaire, Mayor of the station of Vosges de La Bresse, and vice president of ANMSM.

Adaptation mechanisms left out

Several associations, such as Mountain Wilderness and CIPRA (International Commission for the Protection of the Alps) remain benevolent but nonetheless skeptical about the impact of these approaches on the climate threat. "We are faced with a questioning about the future that the mountain world does not want to hear. It reacts extremely conventionally. Changing light bulbs and putting biofuels in gear can not change things, "explains Alain Boulogne, president of CIPRA, who is part of the collective that launched the" call for our mountains "in early December. If the mitigation approach, through the reduction of the carbon impact of the stations, is praiseworthy, on the terrain of adaptation there remains much work to be done in the mountains to change behaviors.

Because threats weigh on tourism, the main source of economic income in the mountains. In the Alps, tourism represents an estimated turnover of 50 billion with 10 at 12% of jobs according to the OECD (2007). If today 91% of Alpine ski areas have a reliable snowfall, they could be only 75% if 1 ° C and 60% increase in case of 2 ° C warming. Water resources, often poorly managed in the mountains (tourism needs, irrigation, etc.) could, according to the EEA (European Environment Agency), become scarce, with a very negative impact on ecosystems and access to drinking water . With an economic model mainly based on snow, many voices are heard about the lack of sustainability of the current systems and the risk incurred by the stations.

An outdated economic model difficult to renew

However, this model continues and the fierce competition that the stations are engaged in begins to cause dramatic situations, especially in the mountains where the lack of snow is already felt. In Saint-Pierre de Chartreuse, despite more investment 925 000 €, the lack of snow has resulted in a fall of 80% of the station's turnover last year and 40 seasonal should not be renewed this year . "The big high altitude resorts are cynical. They say to themselves that if the small stations close, they will gain customers ", is saddened Alain Boulogne. But that will certainly not be enough. "In the big ski resorts, the summer filling is only 15 to 20%. We must strengthen this attractiveness, we are no longer in a logic where we can just open 3 months in the year, "insists Guy Vaxelaire. And for the moment, only some concrete actions are envisaged sometimes helped by regional policies: development of outdoor sports such as hiking, mountain biking or canyoning, enhancement of the agricultural sector but also diversification of winter recreation through the activities "well-being" or cultural, since the stations have now understood that in winter, 1 holidaymaker on 4 does not ski. But for the associations, these initiatives remain at the margins, without in-depth reform of the system. "The longer we wait, the less leeway we have to face the future," warns Alain Boulogne. A speech that is not yet fully heard in all stations.

Pauline Rey-Brahmi


My remark above from 2009 remains valid ... a few days ago it fell 150 cm of snow in less than 48h, it is a record for many alpine resorts!

Global warming does not mean widespread global warming! The thermodynamics of the climate is much too ... subtle ... we saw this last winter with the polar wind sweeping Europe! Cf: https://www.econologie.com/forums/gulf-strea ... 10281.html

Another example: during the 90s there was hardly any snow in the Vosges, while during the 2000s it snowed quite a bit! However the planet was "globally" hotter in the years 2000 than 90 ...

On the other hand, you have to be worried about the "eternal" snows because the summers are beautiful and much hotter! The sea of ​​ice is surely the most ... tourist witness!

Anyway summer skiing is really crappy (iced in the morning, soup in the afternoon), I tested once ... not two! : Cheesy:

The snow melts at sight of average mountain

26 July 2012 The Figaro

The Météo France station of the Col de Porte (1325 m) shows a constant decrease in the duration and the height of the snowfall recorded since 1960.

It is the reference for the middle mountain and the report is not brilliant. The Météo France station installed at the Porte de Col (1325 m) in the Chartreuse massif shows a steady decrease in both the duration and the height of the snowfall recorded since 1960. The average duration of snowfall has decreased by one month and the snow cover duration of more than one meter has decreased by more than two and a half months!

Although this can not be replicated identically in all low-altitude ski resorts, it nevertheless reflects a general trend: low-level skiing will become increasingly difficult. In fact, global warming, which is more pronounced elsewhere in the mountains than on the rest of the territory. At the Col de Porte, the increase recorded is 2 ° C since 1960, against a little less than 1 ° C throughout the territory. Stations below 1500 meters "risk falling below the critical threshold in order to be able to open", announced the Onerc (National Observatory on the Effects of Global Warming) in a report devoted to this issue a few years.

A major challenge

This same document pointed out that the thickness of the snowpack had to go from 1 m to 60 cm in the Northern Alps and from 40 to 20 cm in the Southern Alps and the Pyrenees. "Until the 1990 years, there was no value less than 50 cm," says Gerald Giraud, researcher at the center of study of snow in Grenoble. Since then, it's commonplace, if only for the last three years (2010-2012). At the moment, high altitude stations above 1800 m are not affected. But the projections are not pleasant. By 2050, the climate scenarios - albeit the most pessimistic but which correspond to an extension of the current trend - report a decrease in snowfall of 60%. It would be about 30% to 40% from 1 800 m and 20% to 2 400 m. A major challenge for the managers of these resorts and for all local authorities in the mountains who have made winter tourism a major asset of the Alps.

What's going to be in 2100!

Image

Take a good look at the cover image: it's a reconstruction of the immense Isère glacier that came to die a little over 20 000 years ago in a lake hundreds of meters deep, where is today the city of Grenoble.
At the same time, the site of Geneva was under the ice and the lobe of the Rhone glacier crushed the suburbs of Lyon ... At least ten times during the Quaternary era, the Alps were covered by ice fields that went from Sisteron to Munich! To create these images and to make visible the past glaciations, Sylvain Coutterand studies the traces that the giant glaciers left in the landscape: blocks of rock carried up to several hundred kilometers from their place of origin, planed rocks, moraines covered since long by the vegetation ...

The author traces the birth of this science, geomorphology, whose discoveries have helped to reconstruct the past states of alpine glaciers. More 50 maps are presented in this atlas to take stock of the magnitude of the major glaciations and the speed of current glacier retreat. These images of the prehistory of alpine glaciers are a powerful appeal for reflection at a time when their disappearance is a sad prospect.
If you want to go and see in the field, The Atlas of Disappeared Glaciers offers 10 hikes to explore the most beautiful glaciers in the Alps. It is urgent: "Global warming, if it is not controlled, risks modifying these landscapes to which we are very attached relatively soon," writes climatologist Jean Jouzel, member of the Academy of Sciences in the preface. .

An Italian glacier wrapped in a huge white cloth to limit its melting

23th June 2020

About 100 square meters of white cloth are installed on the Presena glacier, in Italy, in an attempt to limit the damage linked to global warming.

The Presena Glacier, straddling Trentino Alto Adige and Lombardy, has lost more than a third of its volume since 1993. The fault is global warming, and increasingly sunnier summers which make the ice roll back a little each year. more.

This has been the case on the Mer de Glace (the tourist part at least) in recent years ...

Ah to spend money to slow down a phenomenon that does not exist, environmentalists are strong! <<< Any resemblance etc, etc ... fortuitous. : Mrgreen:

Why should we worry about a danger that no longer exists, when the disappearance of glaciers now threatens water resources?
