"Beinahe alle Gebirge weltweit erwärmen sich tendenziell etwas schneller als der Rest der Erde", sagt PIK-Forscher Donovan Dennis. Anlässlich der Flut-Katastrophe in Nepal spricht er über die Bedingungen im Himalaja, über Gletscherforschung und die Folgen des Klimawandels. 👇️ taz.de/Gletscherfor...

Gletscherforscher zur Flutkatastrophe in Nepal: „Gebirge erwärmen sich schneller als der Rest der Erde“

Die Erderwärmung führt zum Abschmelzen der Gletscher. Damit steigt das Risiko von Katastrophen wie jetzt in Nepal, sagt der Glaziologe Donovan Dennis.

I am so tired of waking up, reading the news, and writing an email like this to an American colleague: "Dear [insert career civil servant's name], we read the news of [name of closing lab] with a heavy heart this morning. Please don't hesitate to reach out if we can help." The #NCAR news bites.

The #JuneauIcefield is a deeply meaningful place for me and many others, part of the reason we put so much care into our case study on tipping of Áakʼw Tʼáak Sítʼ (Mendenhall Glacier), one of the icefield's major outlet glaciers. The study is out today as part of the Global Tipping Points Report.

This quote at my SBahn stop hitting differently this week. “What a time it is when talking about trees is almost a crime. Because it involves silence about so many misdeeds!” How I feel coming and going talking about clim. change/Michelangelo, trying to ignore the rising tide in my former home.

Hello world — with little luck, I’m looking for a paper that summarises the history of study of climate change, particularly with respect to glaciers. I.e., what did researchers in the early 20th century think caused the kind of variability that led to terminus position changes? Suggestions?

Just spent the last two weeks crisscrossing the U.S. West with my TIPMIP colleague to talk climate and Earth system tipping points. We’ve learned so much about the state of tipping research in the U.S.! Looking forward to our next stops on the East coast before our TIPMIP General Assembly and AGU!
