In den #Alpen waren Mai bis Oktober 2022 geprägt von Rekordwärme, Regenarmut und einem historischen Gletscherrückgang. Das zeigt die erste Ausgabe von «Alpenklima», einer neuen Berichtsreihe von @DWD_klima, MeteoSchweiz und @ZAMG_AT: https://t.co/NP9OsfM4KF

Zuckerhut? Grand Canyon? Engadiner Blockgletscher! Neu gehören sie in die Gilde der 100 geologischen Welterbestätten der International Union of Geological Sciences.

In a nutshell: we need to turn off the hose as fast as we can, enlarge the drain at all speed, all while learning how to swim + help others learn as well.

The International Union of Geological Science's first list of 100 geological heritage sites is now online.
The list includes geological sites from around the world that are iconic & recognized for their impact in understanding the #Earth & its history

I concluded the summer fieldwork season on #rockglacier Murtèl: last temperature logger readouts, last water sampling of the outflow. All sensors are now ready for the winter. Time for data analysis!

Humans are front and center in the new water cycle diagram from the USGS. It’s the first update to the educational chart used by hundreds of thousands of students in more than 20 years.

The level of ice melt this summer in the Alps has NEVER been observed/measured before 👇👇👇

... and this holds true for several millenia (back to the Holocene climate optimum between 10 and 4 ka) but very likely much further back (last interglacial) !!

[Matthias Huss @matthias_huss]

Dark clouds above dark #glaciers...

Today's @glamos_ch field survey on Glacier de la Plaine Morte indicated enormous melt during the last year, completely beyond the range of everything we had observed so far.
An alarming sign of what still might come in a future, warming world.

finally some fieldwork again - thermal infrared radiometer installations on and in the vicinity of Murtèl rockglacier with great colleagues @amschwand and Nils Rietze 🏔️🌡️ #fieldwork #mountains #TIRLab @uzh_geo

[Dominik Amschwand @amschwand]

Yet, the rockglacier outflow was super low and the streamlet dry. We (actually: Martin :) did our best to measure and sample the little water that emerged at the spring.

[Dominik Amschwand @amschwand]

Back from fieldwork on #rockglacier Murtèl. We heard water flow and measured 9 cm of ice melt since July 7 at our "ablation stake" in a deep furrow (one of the very few spots where the ice surface is accessible beneath the otherwise ~3-5 m thick debris mantle).

[Dominik Amschwand @amschwand]

@JeffNor50595241 @Ecotainment_YT @jbonbon91 @hausfath No, there is actually a third possibility conformable to the laws of thermodynamics: that the heat uptake and temperatures change is not uniform everywhere in the ocean (say: with depth). This is the tacit (and incorrect) assumption in your calculation.

[Dominik Amschwand @amschwand]

I've just re-visited the #Rhone #glacier. The last time I was there was in summer 2017 for fieldwork on the glacier. The spot where we put our crampons on and stepped onto the ice is now in the lake. And that within merely five years! I stood there like petrified. #solastalgia

[Dominik Amschwand @amschwand]

@lubuwetter @weather_talk @matthias_huss @glamos_ch I guess that @weather_talk cares a lot about reliable and trustworthy glaciological data. So does @glamos_ch!

[Dominik Amschwand @amschwand]

@weather_talk @matthias_huss @lubuwetter @glamos_ch They do the glacier mass balance measurements every year since decades, and of course they'll do them also next year. No cycles. Have a look at the data at https://t.co/7luRYhj8tS.
