I don’t have an Instagram account, but thanks to having awesome, and talented friends, our work was featured on the National Geographic Instagram feed in October (I know – I’m slow to post this!) when photographer Robbie Shone joined us on a gorgeous day of fieldwork on Hintereisferner and the neighbouring glaciers. This high mountain valley hosts a scientifically valuable monitoring network, in which institutes including the University of Innsbruck (ACINN and Geography), the Bavarian Academy of Sciences (Commission for Glaciology and Geodesy), and the Tirolean Government (Hydrological Office) measure glacier change, permafrost change, meteorological conditions, precipitation, river runoff and more. These data are useful for understanding how the mountain environment is changing and can be used to develop numerical models of the environmental processes so that we can make useful predictions of future change.

The site is part of several international research networks: UNESCO IHP, GEWEX INARCH, ERB Euro-Mediterranean Network of Experimental and Representative Basins,  The international Long Term Ecological Research network (LTER-Austria, LTER Europe and ILTER), and the basecamp Station  is part of the EU Horizon 2020 INTERACT framework of Arctic (and a few Alpine) research stations.

We were doing two main things on this field work:

Firstly, we were measuring the glacier change. To do this we dig snowpits to record how much snow survived the summer and how much mass it adds to the glacier and also measure the length of stakes drilled into the glacier to record how much the ice surface has lowered, so they know how much ice the glacier has lost at that point over the year. They sum these mass gains and losses like a bank balance to see how the glacier has changed over a year, and extrapolate the changes at each measurement point across the glacier.

 Here I am sampling snow density through the fresh early autumn snow and the snow that survived the previous summer. We need the density of the snow so we can convert the snowdepth into a mass of water – the same depth of heavy wet snow is worth much more water than diamond powder. Photo credit: Robbie Shone.

The data are reported to the World Glacier Monitoring Service. Changes to the Hintereisferner have been measured this way by the University of Innsbruck for over 60 years, making it one of the longest detailed records of glacier change in the world!

Secondly, we were collecting data, and performing maintenance at our meteorological stations. There are six automatic weather stations operating at high elevation in this watershed, and a number of historical rain guages that have been measured for decades.

This automatic weather station is one of the more recent ones, which sits on the surface of Hinterieiferner. Data from this station tells us about the microclimate of the glacier and allows us to relate the pace of surface ice melt to the hour by hour weather conditions. The sensors are supplied by Campbell Scientific and the mast is a self leveling model designed in-house at the University of Innsbruck. Photo credit: Robbie Shone.

Visualizing the retreat of Hintereisferner

Hinteresiferner is the best-studied glacier in Austria with one of the longest records of glacier mass balance in the world. There are relatively abundant old maps and the oldest photographs of Hintereisferner date back to 1884, only 30 years after the Little Ice Age maximum in the Alps. The glacier extent has never been as great since then.

Philipp Rastner published a paper in 2016 (Rastner et al., 2016) describing how one can make appealing vizualizations from a timeseries of digital terrain models. In this publication an animation of the retreat of Findelengletscher in Switzerland was generated, and  using 11 topographic maps and making the assumption that the glacier geometry change between each surface model is linear – meaning the change between two digital terrain models is distributed evenly over the intervening years. This might not be realistic; for example instead of gradual retreat the glacier might have retreated rapidly and then stayed relatively constant, but for vizualizing the cumulative change over time the approach is still useful.

The method involves careful filling of any gaps in the digital terrain models, coregistering them and rendering the animations. From his paper this was done as follows: “All data pre- processing and main processing were performed in the ENVI 4.7 remote sensing and IDL  programming software (Exelis Visual Information Solution, USA). Esri ArcGIS 10.2 and Microsoft Excel were used for the co-registration and Adobe Photoshop for the DEM void filling and artefact removal. The DEM morphing was done in Abrosoft Fanta Morph and the rendering of the computer animation in Visual Nature Studio 3 (VNS; 3D Nature LLC). Finally, all movie  components were matched together in the video editing program Adobe Premiere.”, but you’ll have to read the paper for more details.

Studies based on Austrian glacier inventories (1969, 1979 and 1998) and reconstructions of glaciers at the Little ice Age maximum have revealed the scale of the glacier retreat over this period (Fischer et al., 2015), but Philipp Rastner has also made an animation of Hintereisferner change in the same way as he did for Findelengletscher using a number of alternative digital terrain models of the glacier surface, and here it is:

What can we say for sure about anthropogenic climate change?

Oh sometimes its so hard to find the right words to talk about climate science clearly. At least I struggle with this quite often, but I like the answer given by Dr Kate Marvel within this interview:

Q. What can we say for sure about anthropogenic climate change?

A. First, we know that carbon dioxide is a greenhouse gas. We know what its molecular structure looks like, and we know that this structure means that it absorbs infrared radiation. If we’re wrong about this, we’re wrong about the very basics of physics and chemistry.

Second, we know that burning fossil fuels increases carbon dioxide in the atmosphere. The chemical reactions that produce energy when we burn oil, gas, or coal inevitably produce CO2 as a byproduct. And that CO2 goes into the atmosphere. We have excellent measurements of atmospheric CO2, and they clearly show a dramatic increase since the industrial revolution.

Third, we know the climate has been changing. Multiple independent datasets show the global temperature rising. But that’s not all that’s been happening. There is more water vapour in the atmosphere. Spring is coming earlier. Rainfall patterns are shifting. Glaciers and sea ice are melting. There are more and deadlier heat waves.

Fourth, we know that these changes are very, very likely to be due to human activities. We know that the climate changes due to natural factors, but we also have a fairly good understanding of what the climate would look like without us. We can model this natural variability using powerful supercomputers, and we can also study the climate of the past using things like tree rings and ice cores. The changes we’ve observed are too large and too rapid to be attributable to any known natural factors. And they’re very consistent with what we expect increased carbon dioxide to do to the planet. An alternate explanation would have to come up with a plausible natural mechanism for these changes and explain why CO2 doesn’t act the way we think it should – and that’s a very tall order.

Here is Kate talking about climate modelling and clouds in a TED talk:

Also, from her website, a lesson in how to write succinct research summaries:

“My postdoctoral work identified a “fingerprint” of human influence on global precipitation patterns and showed that we are already changing rain and snowfall. This is both reassuring, because it suggests climate model projections are credible, and terrifying, because it suggests climate model projections are credible.”

 Ha ha! thank you Dr Marvel.

Determining supraglacial debris thickness from terrestrial photographs

Big shout out to my colleague Jordan Mertes for an excellent and fun collaboration – our new paper in Journal of Glaciology is online now.

Nicholson, L. and Mertes, J. (2017) Thickness estimation of supraglacial debris above ice cliff exposures using a high resolution digital surface model derived from terrestrial photography. Journal of Glaciology. doi:10.1017/jog.2017.68

Years and years ago when I was doing my PhD we wanted to get an idea of how thick the layer of rubble and dust was over the Ngozumpa glacier (in the photo below – this is the biggest glacier in Nepal and the lower 12-15 kms of it are covered in rock debris/rubble). To find out more about debris-covered glaciers like the Ngozumpa, have a look here.

Its pretty unrewarding work to dig through this kind of rock debris overlying the ice, but the debris covered part of the glacier is studded with steep bare ice cliffs, above which the rock debris layer can be seen in a vertical section. So, to avoid digging holes, we hit on a good idea that involved Doug Benn running round the crest lines of these exposed cliffs with a surveying reflector while I surveyed his position from the glacier side moraine, using a theodolite to measure the dip and distance to the reflector and also the dip to the debris-ice interface beneath him. Using simple trigonometry, and imagining the ice cliff geometry to be simpler than it really is, we could use these measurements to get an estimate of the debris thickness visible above the cliffs.

The world moves on. Now simple photographs can be used with some very cool software (Structure from Motion – Multi View Stereo processing software to be precise) to relatively easily make digital 3D surface models. It occurred to me that the kind of measurements I did in my PhD could be done readily, and probably more accurately, from a high-resolution terrain model. In spring 2016, Anna Wirbel and I took a bunch of photos of ice cliffs to see how it would go.

The short answer is: it turned out rather nicely. Below is an oblique view of the surface model we made from our photos and the coloured dots forming lines along the ice cliff crests show the implied debris thickness (hd) in centimetres along the three ice cliffs we took pictures of. For an idea of scale the cliff peak furthest away is almost 45m high. The numbered red and yellow dots are ground control points that were accurately surveyed and used to scale the model correctly.

For the long answer you can read the paper – its freely available online 🙂

I’d really like to see if the lower resolution, but closer-to-target, imagery from UAVs, that are now almost regularly flown over debris-covered glaciers can also be used to perform similar debris thickness assessments at a glacier scale. I don’t have a UAV though …. so I hope someone else will do that with their UAV images!

3D models of glaciers from Erik Schytt Holmund

I follow Erik Schytt Holmund (a student at Stockholm University) on sketchfab (a website for storing and viewing 3D surface models) where he posts some awesome ‘Structure from Motion – Multi View Stereo’ (SfM-MVS) surface models of glaciers and other geomorphological phenomena, extracted from photographs, both old and new.

Check them out here: https://sketchfab.com/ErikSH/models

Here for example is the Tarfaladalen in 2017, site of many famous Swedish glaciological studies.

Open Access-Policy of the University of Innsbruck

I was just at an interesting presentation about University of Innsbruck open access publishing policies in which I learned some new things. Generally, there are two types of open access:

  • Gold – refers to articles in fully accessible open access journals = the best way in my opinion
  • Green – refers to self-archiving generally of the pre- or post-print in repositories = in which the publisher weirdly wishes to prevent re-using of its layout, but not your content
  • Hybrid – refers to subscription journals with open access to individual articles usually when a fee is paid to the publisher or journal by the author, the author’s organization, or the research funder = the way in which publishers reap double payment from the author and the subscriber

The information for our University is here: https://www.uibk.ac.at/open-access/ and the policy is:

The University of Innsbruck expressly supports open access publications and thus the free and sustainable approach to scientific knowledge. As a matter of social responsibility, open access facilitates the transfer of scientific findings into society. Furthermore, free access to scientific and scholarly publications enhances their visibility in the international scientific community and facilitates their long-term archiving and permanent citeability. For these reasons the University of Innsbruck signed the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities.

To this effect, the University of Innsbruck expects its members (in accordance with the University Act of 2002 §94) to deposit already published publications in the institutional repository of the University of Innsbruck – Open Access, after expiration of the adequate waiting periods („green road“). Any new work should be first published directly in open access journals or in the form of open access monographs, if appropriate journals or series with quality assurance procedures (e.g. peer review) can be found („golden road“).

Therefore, the University of Innsbruck expressly recommends to its members to reserve the contractual rights to any form of use of the open access publication, like especially the rights of reproduction and making the publication available online.

Furthermore, the University of Innsbruck advises its members to also free the access to their research data.

The University of Innsbruck assists its members in the realization of these recommendations through relevant information and advice from the coordination centre for open access at the Universitäts- and Landesbibliothek Tirol (University and State Library of Tyrol),

  • the institutional repository of the Universitäts- and Landesbibliothek Tirol (http://diglib.uibk.ac.at),
  • the university’s publisher innsbruck university press (iup),
  • the infrastructure provided by the iup and the ZID (information technology services of the University of Innsbruck) for the publishing of open access journals,
  • measures to provide research data,
  • a publication fund to finance author charges that may accrue during the publication, as well as
  • the change of journals published by members of the University of Innsbruck to open access. New establishments only receive financial support if published as open access journals with adequate quality assurance procedures.

Publications that were published through open access will from now on be specifically identified in the documentation of research performance.

We are encouraged to upload all student theses to the repository, as well as any of our publications that are not gold access, subject to the restrictions that can be looked up on the SHERPA/romeo database. Funding OA publications can get complicated: sometimes the project funder pays (like the FWF does), the University has a fund but also some publishers issue institutes a number of publication vouchers, and its worth checking if your publication is eligible for these support options. To be honest in my field I feel massively lucky that journals like The Cryosphere (and all the other Copernicus Journals) and Journal of Glaciology are Gold open access.

And, as a follow up, here is an interesting related article from the Guardian newspaper: Is the staggeringly profitable business of scientific publishing bad for science?

Zenodo data repository

Many scientific journals now ask for data used and processing computer code or software developed  in the study to be openly shared – which is as it should be. Most university research is publicly funded and therefore should be publicly available.

I always had troubles finding a good place to supply this data if the journal does not have its own means of storing supplementary material along with the journal. However, today it came about that I really had to sit down and find a data repository option that would work for large files and i have settled upon Zenodo. The EC commissioned the OpenAIRE project, to lead open access and open data movements in Europe in support of their nascent Open Data policy by providing a catch-all repository for EC funded research. CERN, an OpenAIRE partner and pioneer in open source, open access and open data, provided this capability and Zenodo was launched in May 2013.

Zenodo seems to really make it easy to upload all sorts and any size of data or other contribution, assign a digital object identifier (used as a permanent reference for this contribution)

For example here Simon Gascoin uploaded Satellite images of the 17 July 2016 Aru Co glacier collapse in Tibet. Below is a GIF animation switching between two of the images uplaoded:

  • Sentinel-2A image of the Aru Co glacier avalanche acquired on 21-Jul-2016 (4 days after the event). RGB composite of bands B4,B3,B2 scaled to bytes between 0 and 0.5 from level 1C product (orthorectified top-of-atmosphere reflectances).
  • Landsat-8 image of the Aru Co area acquired on 24-Jun-2016 (23 days before the event). RGB composite of bands B4,B3,B2 scaled to bytes between 0 and 0.5 from level 1C product (orthorectified top-of-atmosphere reflectances).

The Aru Co glacier collapse was a surprise as it was a huge mass glacier movement of a kind not previously documented. A good description of the event, and a second glacier collapse from the same range a few weeks later can be found here.


I feel like I should have been using this for a long time, and I guess I will start uploading some datasets there in the coming days and weeks.

My first dataset is up there now: Ngozumpa Glacier Gokyo ice cliffs photographic surface model, which is based on photographs taken in April 2016.

How do penitentes change over a summer?

I just noticed that in our paper in which we presented measurements of the changing surface morphology of penitentes on a glacier in Chile, the main figure which was supposed to use transparencies does not in the final production version. So I thought I’d put this version of how it was supposed to look on here:

The two columns show two different, but nearby, sites: A (7.00 m2) and B (2.25 m2).

The top panels show the hypsometry (area-altitude distribution) of the surface over time (colours shifting from greenish to purple over 25 Nov, 11-Dec, 20-Dec, 03-Jan), by plotting the % distribution of surface elevation showing that while the overall surface lowers, its relief (the vertical spread of the hypsometry) increases.

The second panels show that as the surface lowers, and the relief increases, the penitentes steepen.

The third panels show the aspect distribution of the surface, indicating the strong east-west alignment of the penitentes, and also showing a slight rotation of the alignment over time as the path of the sun alters over the course of the summer.


Nicholson, L. I., Petlicki, M., Partan, B. and Macdonell, S.: 3D surface properties of glacier penitentes over an ablation season , measured using a Microsoft Xbox Kinect, The Cryosphere, 10, 1–31, doi:10.5194/tc-2015-207, 2016.

Magazin Interview St Anton Filmfestival (Deutsch)

Es ist immer interessant und lohnend, über meine Forschung interviewt zu werden, aber es ist schwierig,  die richtige Balance zu finden, wenn man die Wissenschaft kommuniziert, damit jeder die Hauptbotschaft, aber auch die wichtigen Nuancen unseres gegenwärtigen Verständnisses versteht.

Ich wurde vor kurzem für das Magazin des St. Anton Film Festivals interviewt und mir wurde geraten, mich darauf vorzubereiten über den Gletscherwandel in den Alpen zu sprechen. Ich habe  einiges nachgelesenund  einige Gletscheränderungen in Tirol überprüft, aber am Ende war das Gespräch mehr über den Klimawandel und persönliche Meinungen darüber, wie wir damit umgehen können. Also grundsätzlich bin ich stark von dem abgewichen, was ich vorbereitet hatte. Ich glaube, ich hätte in einigen Punkten den Schwerpunkt lieber  ein bisschen anders  gesetzt. Also dachte ich, ich würde es hier mit einigen Kommentaren (in braun) wiedergeben. Das ist also ein massiver blog!

Lindsey, gibt es den Klimawandel wirklich, oder ist er nur von den Chinesen erfunden?
Es kommt darauf an was man mit „Wandel“ meint. Das Klima unseres Planeten hat sich über die Jahrmillionen fortlaufend geändert. Belegt ist jedoch, dass die Menschen seit der Industriellen Revolution das Klima beeinflussen, und zwar durch die Menge an Energie, die in der Atmosphäre angereichert wird. Wir haben aber wiederum die Möglichkeit, diesen anthropogenen Klimawandel zu beeinflussen.

“Klimawandel” ist für Erdwissenschaftler ein Ausdruck, der schwierig zu handhaben ist. Die Frage dreht sich eigentlich um den vom Menschen verursachten Klimawandel. Welcher real ist. Durch die Veränderung der Zusammensetzung unserer Atmosphäre (durch die Verbrennung fossiler Brennstoffe, die Veränderung der Landnutzung usw.) ändern wir die Menge der Sonnenenergie, die sie speichern kann. Das ist einfache Physik und  es ist unbestreitbar, dass menschliche Aktivitäten dies verursachen. Die zusätzliche Energie wird als Wärme in der Luft und im Ozean gespeichert. Was komplizierter zu bestimmen ist,  ist, wie genau sich das gesamte System Planet ändern wird, wenn sich diese Menge an gespeicherter Energie ändert und wo diese Veränderungen zuerst / am stärksten zu spüren sein werden.

Schauen Sie sich diese coole Feature vom NASA Earth Observatory für weitere Informationen und Erklärungen an: https://earthobservatory.nasa.gov/Features/GlobalWarming/page1.php. Klicken Sie im Index oben rechts durch die 6 Seiten, um einen vollständigen Überblick zu erhalten.

 Warum ist der Klimawandel eigentlich etwas Schlechtes?
Das globale Klima hat sich um 1,5°C in den letzten 200 Jahren erwärmt. Es gibt Forschungen, die belegen, dass ein wärmeres Klima vorteilhaft für einige Teile der Welt wäre. Die negativen Auswirkungen eines wärmeren Klimas überwiegen dennoch und sind primär mit dem Anstieg des Meeresspiegels verbunden. Wenn sich die Ozeane erwärmen, dehnen sie sich aus, das ist einfache Physik. Dazu kommt das weltweite Abschmelzen des Landeises.

Weltweit muss man erwarten, dass die Auswirkungen auf die menschlichen Gesellschaften negativ sein werden, da wir unseren aktuellen Lebensstil entwickelt haben in Anpassung an klimatische Bedingungen, die wir  hinter uns lassen. Schauen Sie als Beispiel dafür auf Joy Plot (benannt nach der Joy Division übrigens) GIF (von Dr Gavin Schmidt via www.realclimate.org) um zu sehen, wie sich die monatlichen globalen Temperaturen (GISTEMP Daten) in den letzten Jahrzehnten verändert haben:

Es gibt viele Veränderungen, die sich aus einem wärmeren Klima ergeben, die die Menschen (und ihre Umwelt) negativ beeinflussen können Es ist meine persönliche Meinung, dass der Meeresspiegelanstieg eines der klarsten Probleme ist, denen wir begegnen müssen: Ich kenne keinen Platz auf der Erde,  der sich durch einen steigenden Meerespiegel für den Menschen verbessert.

Es gibt viele Veränderungen, die sich aus einem wärmeren Klima ergeben, die die Menschen (und ihre Umwelt) negativ beeinflussen können Es ist meine persönliche Meinung, dass der Meeresspiegelanstieg eines der klarsten Probleme ist, denen wir begegnen müssen: Ich kenne keinen Platz auf der Erde,  der sich durch einen steigenden Meerespiegel für den Menschen verbessert.

 Und das betrifft wiederum Millionen von Menschen.
Genau, die meisten Menschen leben in Küstenregionen. Mit dem Jahr 2100 erwarten wir einen Meeresspiegelanstieg um einen Meter, und darauf müssen wir uns vorbereiten. Wenn ein massiver Sturm und die Flut zusammentreffen, kann das große Schäden anrichten. Dazu kommen noch Dürren in vielen Regionen der Welt und ein häufigeres Vorkommen von Extremwettereignissen. Der Klimawandel wird die größte geopolitische und humanitäre Herausforderung für unsere Nachfolgegenerationen sein.

Ich habe das schlecht ausgedrückt. Ich hätte ‘viele’ Menschen sagen sollen, aber ich hatte die Zahlen nicht bereit. Tatsächlich leben 250 Millionen Menschen innerhalb von 5m des heutigen Meeresspiegels. Nicht alle werden vom örtlichen Meeresspiegelanstieg betroffen sein, aber einige Gemeinden werden Überflutungen, Erosion und Sturmfluten erleiden aufgrundeines  Meeresspiegelanstieges von 1 m bis zum Ende des Jahrhunderts. Unsere Gesellschaft muss bereit sein, die am stärksten betroffenen Menschen auf eine humanitäre Art umzusiedeln und mit Verlusten in der Küsteninfrastruktur umzugehen.

 Warum ist Klimawandelforschung überhaupt noch notwendig?
Unsere Fähigkeit, zukünftige Umstände vorherzusagen, ist auf Grund der Datenmenge und -Interpretationsmöglichkeiten im letzten Jahrzehnt sehr viel besser geworden. Wir finden immer wieder neue Dinge oder können bestehende Vorhersagen detaillierter angeben. Dennoch glaube ich, das, was wir jetzt im Moment viel dringender brauchen, ist aktives Handeln – von politischer und persönlicher Seite. Wir wissen ja, dass sich unser Klima ändert und wir wissen, dass wir etwas tun müssen.

Ja, manchmal kann es in der Klimaforschung entmutigend sein. Wissenschaftler haben den Entscheidungsträgern über die IPCC-Berichte (Intergovernmental Panel on Climate Change) eine Vielzahl von State-of-the-Art-Informationen übermittelt, aber trotz des bedeutenden Fortschritts durch die Pariser Vereinbarung, könnte politisches Handeln noch zu langsam sein. Manchmal kann es sich so anfühlen (von kudelka cartoons):

Auch bleiben viele Mitglieder der Öffentlichkeit  skeptisch gegenüber der Zuverlässigkeit der Botschaften des IPCC. Dies bleibt die Verantwortung der Wissenschaftler und der sachkundigen Regierungen, die Beweise für die Botschaften aus dem IPCC-Bericht weiterzugeben, so dass weniger Zeit in öffentlichen Diskussionen vergeudet wird, über Dinge, die wir wissen, dass passieren, Stattdessen kann mehr Zeit und Energie aufgewendet werden um machbare Strategien zu entwickeln zur Minimierung des potenziellen Leidens, das durch den vom Menschen verursachten Klimawandel für uns und unseren Planeten verursacht werden kann..

 Können wir den Klimawandel noch stoppen?
Was die Alpen betrifft, werden wir die Gletscher nicht mehr retten können, die werden in ca. 60 Jahren verschwunden sein. Das ist genauso gewiss wir der Meeresspiegelanstieg. Auch wenn wir unseren CO2-Ausstoß sofort stoppen würden, die Auswirkungen des CO2-Ausstoßes des letzten Jahrhunderts müssten wir trotzdem tragen. Gletscher z. B. brauchen 20-30 Jahre, um auf Veränderungen in der Atmosphäre zu reagieren, und viele andere Systeme ebenso.

Schadensbegrenzung ist möglich, und ich denke, wir sollten dafür sorgen! Aber es ist wahr, dass die Zukunft unserer Gletscher hier in den Alpen ein wenig düster ist, wie ich hier zusammengefasst habe.

 Wir alle wissen, dass wir global gesehen unseren Verbrauch an fossilen Brennstoffen reduzieren müssen. Leichter gesagt als getan – was können wir als Einzelpersonen machen?
Wir können ganz simple Sachen machen, wie z.B. auf Papier- und Plastikbecher verzichten, die eigene Wasserflasche immer wieder auffüllen, Carsharing mit Freunden betreiben, darauf Acht geben, dass man wenig Müll produziert, biologische Lebensmittel und wenig Fleisch kauft. Mit diesen Dingen kann jeder von uns sofort beginnen. Das würde vielleicht auch den Weg zu einem achtsamen Miteinander ebnen, das wir definitiv brauchen werden, wenn die Umweltbedingungen für viele Menschen auf diesem Planeten dramatisch schlechter werden.

Ich möchte nicht sagen, dass keine Papierbecher zu verwenden uns retten wird. Mein Punkt hier ist, dass wir, indem wir eine prinzipientreue, persönliche Haltung einnehmen, wir die Menschen um uns beeinflussendas Gleiche zu tun. Auf diese Weise bereiten wir unsere Gesellschaft vor, gemeinsame Gesetzesänderungen vorzunehmen, die notwendig sind, um das Ausmaß, in dem wir unser Klima weiter verändern werden, wirklich zu ändern.. Ich glaube übrigens, dass wir es schaffen können.

Vielen Dank an das St Anton Film Festival für die Chance, mit ihnen zu sprechen. Danke an die Teilnehmer des Films Guilt Trip, die es für wichtig hielten, die Umwelt  zu beachten in der Planung ihres Abenteurs und in der Produktion ihres Filmes. Vielen Dank auch an Manuela Lehner für die Korrektur meines bisher schrecklichen Deutschen.
