World’s Largest #CarbonCapture Plant Switched On In #Iceland

A machine capable of removing 4,000 tons of CO2 from the air each year

Hmm, we emmit approx. 1337 t #CO2 per SECOND...
--> https://www.mcc-berlin.net/en/research/co2-budget.html

...that means with this plant we can remove ~3 seconds of current #emissions in ONE YEAR.
In other words: this plant removes 0,13 kg CO2 per second....

... that means we need additional 10.540.908 of these plants ... to remove current emissions.

"There’s no time to wait around, there’s no time for continued inaction – the people deserve to know NOW what our corporate owned politicians have done to them.
The report explicitly states that incremental change is not a viable option."

Der September rückt näher und damit ist es Zeit für das 2. Bits&Bäume-Online-Community-Treffen: 02.09., 18-21h 🙌

https://discourse.bits-und-baeume.org/t/2021-09-02-bits-baeume-vernetzungs-treffen-online/1097

Jeden 1. Do. im Monat findet ein B&B-Vernetzungstreffen statt. Alle 3 Monate ist das dann etwas größer. Das Programm ist noch in Arbeit, aber der Rahmen steht:

Onboarding, Lightningtalks, Workshop, OpenSpaces, Vernetzung

Wer sich mit einbringen möchte: am besten auf Foren-Beitrag antworten. Sonst gerne auch Mail an community-treffen<ät>bits-und-baeume.org

Thunberg protests in Stockholm on third anniversary of first school strike

Thunberg's grassroot initiative caught on around the world, with millions rallying at weekly "Fridays for Future" protests to call on world leaders to listen to scientists about, and act to stop, climate change, and in 2019 the Time magazine named ...

Weltklimabericht: Auch Zwei-Grad-Ziel am seidenen Faden

Bei weiter steigenden Treibhausgas-Emissionen ist die Welt nur noch drei Jahre davon entfernt, selbst das Zwei-Grad-Klimaziel zu verspielen. Diese Gefahr sieht der Weltklimarat laut einem durchgesickerten Berichtsentwurf. Von Volker Mrasek.

#Klimawandel und #IT, was getan werden kann:
- Nutzt eure Geräte solange sie funktionieren
- Wenn Neuanschaffung nötig ist, kauft refurbished Geräte
- Nutzt sparsame Geräte
- Nutzt sparsame Betriebssysteme, diese laufen auch besser auf älterer Hardware (vor allem Linux).
- Beim Streaming SD oder maximal HD nutzen, 4K ist ein Klimakiller

I am looking for volunteers who could translate my article on Frugal Computing (low-carbon, sustainable computing), preferably in Chinese, Japanese, Spanish and French, but other languages are also very welcome.

Thanks for boosting!

Environmental concerns grow as space tourism lifts off

After years of waiting, Richard Branson's journey to space this month on a Virgin Galactic vessel was supposed to be a triumphant homecoming. Instead, the jaunt attracted significant criticism—about its carbon footprint.

https://phys.org/news/2021-07-environmental-space-tourism.html #climateemergency #pollution #environment #ecology

I wrote an article about the need for low-carbon and #sustainable #computing and the path towards zero-carbon computing.

tl;dr:

** The problem:
* By 2040 emissions from computing alone will be close to half the emissions level acceptable to keep global warming below 2°C. This growth in computing emissions is unsustainable: it would make it virtually impossible to meet the emissions warming limit.
* The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices.
** The solution:
As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving the same results for less energy.
** The vision: please read the article, I'm out of characters.
