Glacier melt - Storyboard of our visit on the "Aletschgletscher"

28 May 2021, Aletschgletscher (VS)

Our journey started at 03:30, as we woke up. Then we prepared us for our trip to the "Aletschgletscher". Firstly took the train from Winterthur at 04:30 to arrive to Zurich. There we took the train to arrive to Bern. After that, we took another train to arrive to Interlaken Ost. Lastly, we took an interregional train from Interlaken Ost to arrive to Grindelwald "Terminal".

When we arrived at the «Terminal» of the Jungfraujoch, we saluted our team. There was Prof. Dr. Daniel Farinotti, his student Jane, Mrs. Suter, two camerca guys and a women as well as a guy that where there as investors from the market agency "La Prairie". More...

Glacier melt - Interview with Prof. Dr. Daniel Farinotti

This interview was taken the 28 May 2021 directly on the "Aletschgletscher"

- Is "artificial snow" efficient enough to save glaciers?

- "It is instantly efficient, but in general I think that glaciers are condemned to die. So the glaciers won't grow in the future."

- Do you know countermeasures to stop the glacier melt?

- "Artificial snow is only one possibility. Another one is to reduce the emissions."

- Will you vote for the "glacier initiative"?

- Obviously!

- Is it realistic to reduce the emissions to zero by the year 2050 as the Paris climate agreement wanted?

- I think it's not so realistic.

- Is water more important than the fundamental part of a glacier?

- Sure it is! A glacier consists to 99% of water.

In the next week, we will have four other questions for Prof. Dr. Dario Farinotti, that today was very occupied during his research on the "Aletschgletscher".

Glacier melt - Interview with UZH

This online interview was taken the 13 May 2021 with Sanja Josi, the leader of Hydrologic Commission of the UZH

- Which concrete measures can we use to save our glaciers?

Everything that stops global warming helps to reduce glacier retreat in the long term (the adaptation period is long, however: even if we stop warming today, most glaciers will still lose a lot of mass and adapt to the rise in temperature of recent years / decades - therefore we have to act now).

- Is artificial snow the right idea to save glaciers?

No, a glacier can't be saved with artificial snow. It takes a lot of energy to make artificial snow... that would be counterproductive. I think the energy consumption for making artificial snow is obviously very high and not feasible for entire glaciers. If it is about small sections, e.g. the transition from one station to the Ski slope, then that brings something locally, but it is for entire glaciers pointless. Glaciers are climate indicators and are controlled by the climate. If the climate is "hostile to glaciers", there are no good long-term forecasts. And therefore no alternatives to reduce further warming.

- Is there any way to stop the general rise in sea levels?

If we could stop the glacial melt, so will the proportion the rise in sea level associated with glacier melt, fall away.

- What should we do with the meltwater runoff?

What are the consequences of eruptions from glacial lakes? Regarding the glacial lakes: these are questions about natural hazards that often have very local characteristics (Permafrost distribution, geometry of the glacier, ...), there are many factors that come together; as e.g. the current case in India has shown. It seems that lakes are increasingly being formed / will be in the future. The extent to which these then represent a hazard or a risk depends on many local factors.

- Are there any new reasons for the melt of glaciers?

There are actually no new reasons for the glacier melt. Knowledge is physics. But there are better data around the world for glacier distribution and ice thicknesses (https://www.nature.com/articles/s41586-021-03436-z). And some things seem to be accelerating where they were until recently said it will take longer.

German version

Dieses Online-Interview wurde am 13. Mai 2021 mit Sanja Josi, der Leiterin der Hydrologischen Kommission der UZH, geführt

- Mit welchen konkreten Mitteln können wir unsere Gletscher retten?

Alles was die globale Erwärmung verringert, stoppt trägt langfristig
dazu bei den Gletscherschwund zu reduzieren (die Anpassungszeit ist allerdings lang: selbst wenn wir die Erwärmung heute stoppen, werden die meisten Gletscher noch viel Masser verlieren und sich an die Temperaturerhöhung der letzten Jahre/Jahrzehnte anpassen - daher müssen wir jetzt handeln).

- Welche Gegenmassnahmen können wir ergreifen?

Ist Kunstschnee wirklich das richtige Mittel, um Gletscher zu retten? mit Kunstschnee lässt sich kein Gletscher retten. Es braucht immens viel Energie um Kunstschnee herzustellen... das wäre kontraproduktiv.

- Ist die generelle Erhöhung des Meeresspiegels irgendwie zu stoppen?

Wenn wir die Gletscherschmelze stoppen könnten, wird auch der Anteil des Meeresspiegelanstiegs, der mit der Gletscherschmelze zusammenhängt, wegfallen.

- Was tun mit dem Schmelzwasserabfluss?

Die Eruption von Gletscherflüssen führt zu welchen Folgen? (Eruptions from glacial lakes) - zu den Gletscherseen: das sind Fragen zu Naturgefahren, die oft sehr lokale Charakteristiken haben (Permafrostverbreitung, Geometrie des Gletschers,...), hier gibt es viele Faktoren, die zusammenkommen; wie z.B. der aktuelle Fall in Indien gezeigt hat. Es scheint, dass es vermehrt zur Entstehung von Seen kommt/in Zukunft kommen wird. Inwieweit diese dann ein Gefahr oder ein Risiko darstellen, hängt von vielen lokalen Faktoren ab.

- Gibt es zu den Gründen für das Schmelzen der Gletscher neue Ergebnisse? Neben Wikipedia und anderen Websites haben wir uns über https://ecobnb.de/blog/2020/05/gletscherschmelze-gruende-folgen/ [1] darüber zu erkundigen versucht.

Zu den Gründen für die Gletscherschmelze gibt es eigentlich keine
neuen Erkenntnisse, das ist Physik. Es gibt aber weltweit bessere Daten zur Gletscherverbreitung und Eisdicken (https://www.nature.com/articles/s41586-021-03436-z). Und manches scheint sich zu beschleunigen, wo man bis vor kurzem noch meinte, dass es länger dauern wird.

Glacier melt - Survey preparation

27 april 2021

In the next days, we will prepare a survey about glacier melt.

Then the general idea for our collaboration with "Team Kerala" is to show heavy results on climate change. So as reported in the last post, we will bring together our results with those of "Team Kerala". They already wrote:

What are these effects? Let us go through some of them :
*Increase in global temperature*, which leads to:
*Melt of Glaciers*, as a result of which there will be a :
*Rise in Sea level*,
*Increase in precipitation and Imbalance of monsoon* which can become a major cause for :
*Floods*,
*Extinction of species* (as we saw in the beginning of the article ), that may cause:
*Ecological Imbalance*,
*Ocean Acidification* and the list remains *endless*.
So climate change is a problem that shouldn't be ignored, by anyone at anytime. In fact, it has already started creating problems on our planet.

Glacier melt - Collaboration with Team Kerala

23 April 2021

Today we talked with "Team Kerala" about our collaboration-plan.

We also created on WhatsApp a chat called "Team Kerala", which is used for our exchanging ourself. In the next weeks, we will have another meeting via Google. In that occasion, we will bring together the results of the surveys about glacier melt and floods.
