  2. 🐢🎶 Ah, the age-old #debate of #resampling audio: a riveting tale of 3.9 kHz that nobody asked for. Kevin Boone bravely ventures where no one has gone before, exploring the thrilling world of #sampling #rates and #DACs on your handheld device. Spoiler: it’s as exciting as watching paint dry, but with more numbers. 📉🔊

  3. Gestern haben wir & unsere Kolleginnen und Kollegen aus dem BMI einen Einführungsvortrag zu 📂#OpenData
    vor den #DACS Studierenden der #HsBund gehalten.🏫
    Anschließend gab es einen Workshop zum Bereitstellungsprozess offener Daten.👩‍🎓
    Wir bedanken uns für das große Interesse an offenen Daten!🙏

  4. Forests can't be used in NDC (nationally determined contribution).Forests are in adaptation mode, that is, death by drought, bugs, fires, until new ecosystem members have moved in long after °C is stabilized.
    Trees adapt to longer growth seasons, higher temperatures, over-fertilisation by CO2. This means less water and nutrients and makes them unhealthy.

    Trees only park our CO2, then they burn.

    #Koutsodendris et al 2020 counted pollen at Lake Ohrid, Albania.
    Look at the gap between rising °C 🟡 vs rising pollen count for temperate/mesophilus trees 🟤 🟢.

    Adapting to a new climate takes time, even with seed-carriers and migration corridors: 1000yrs until new ecosystem members have moved in and adaptation to a new stable climate is accomplished.

    But we don't have migration corridors. We have settlements and agricultural wastelands with pesticides everywhere.

    Also, sinks start outgassing once ppm drops. So if your #NDC include negative emissions by DACS or CCS to undo a temperature #overshoot, to really remove 1t CO2 from the system, you must remove 1.5t once we're in the negative emissions phase.

    Outgassing is a physical process to balance changes in atmosphere composition. But of course, when ppm drops considerably, it also changes °C and regional climate and hydrological cycles – again. So your ecosystem is going into adaptation mode all over again. Forests burn.. again.

    Overshoot scenarios aren't a good idea, even if we had working technology and concepts. CO2 removal adds another stressful phase and prolongs adaptation to changing factors – for us and our human systems, and for ecosystems on land and in the ocean.
