#TLDR:
#Rußpartikel aus #Kerosin für #Raketen von #SpaceX verbleiben jahrelang in oberen Atmosphärenschichten. Die abschattende Wirkung beeinflusst das #Klima 540x effektiver als bodennaher #Ruß. Für 2029 sind rund 870 Tonnen Rußausstoß durch die #Raumfahrt prognostiziert. Die Folgen dieses unkontrollierten #Geoengineering / #Solarengineering sind derzeit nicht abzuschätzen, aber jedenfalls drastisch.

Ungeplantes Geoengineering: Aufbau von Starlink & Co. mit Folgen für Atmosphäre Jedes Jahr werden immer mehr Raketen gestartet, vorrangig mit Starlink-Satelliten. Die Folgen für die Erdatmosphäre sind womöglich weitreichender als gedacht. https://www.heise.de/news/Ungeplantes-Geoengineering-Aufbau-von-Starlink-Co-mit-Folgen-fuer-Atmosphaere-11294723.html?wt_mc=sm.red.ho.mastodon.mastodon.md_beitraege.md_beitraege&utm_source=mastodon #Forschung #Klimawandel #Raumfahrt #SpaceX #Starlink #Wissenschaft #news

But real operation is:
200–600 W/m²
Cloud cover
Diffuse light

So performance doesn’t fail at peak.
It fails in daily conditions.

The real question is:
Which systems stay stable when irradiance drops?

That’s where quality, not branding, shows up.

I've posted a little recently on my concerns about #geoengineering and #solarengineering approaches to tackling the symptoms but not the causes of #climatechange

In particular, I've expressed my concerns that such 'technology solutions' can or will create a belief that we can be relaxed about #carbonemissions now as future technology will save us in the future.

Whilst I think this is a hugely dangerous approach and worse still provides continuing camouflage and a licence to pollute for the #fossilfuel industry, there are nevertheless some researchers who consider research on these new technologies is vital. For some balance then, I'm sharing this considered exploration of the issue in an opinion piece in Nature advocating for the research to be done.

Personally, I believe a moratorium is needed now on all solar- and geo-engineering whilst we instead and firstly, put in place genuine plans and legislation for rapid global emission reductions and stop all new fossil fuel projects, rather than continuing with our current pathway of hollow pledges from governments and the smoke and mirrors of offsets and gas transitions.

Sadly though, we know the work on these climate mitigation technologies will go on anyway as we can already see from recent private start-up activity. Mirroring what is happening in the #AI arena (witness #ChatGPT) the genie is out of the bottle - a very dangerous place to be.

Solar geoengineering is scary — that’s why we should research it

Research on blocking sunlight needs a dose of realpolitik.
