#planetaryboundary — Public Fediverse posts

More than half of the world’s land area is in a precarious state, according to a new study mapping the #PlanetaryBoundary of functional biosphere integrity - in spatial detail and across centuries. 38% of global land is already in the high-risk zone.

this week's feature in #CurrentBiology is about #oceanAcidification - the 7th #planetaryBoundary we've crossed. https://proseandpassion.blogspot.com/2025/08/oceans-acidified.html #science #environment #ClimateCatastrophe #marineBiology #oceans

So I learned yesterday, that Aluminium Oxide is very bad for the Ozone Layer

Also learned, there are currently 6000 #Starlink satellites that gravitate around Earth and plan is to send 12000 more in the coming years.
They have a life expectancy of 5 years, and each one of them produce about 30kg of Aluminium Oxide when burning in the atmosphere...

So, in short, #Musk is screwing up, the only #planetaryBoundary we almost crossed and managed to revert from...

#NateHagens new podcast episode with #Rockström ! https://www.youtube.com/watch?v=JaboF3vAsZs

Good questions by Nate, intermediate level answers by Rockström. About the 9 #PlanetaryBoundary , a bit about the 16 tipping elements, the inter-connectedness of it all. I hope, especially techies give this episode a go. Because: phasing out fossil fuels is not enough to successfully combat #ClimateChange . We do need a healthy planet to do this. An Earth system that helps us buffering the stress we caused by GHG.
Novel Entities kill biodiversity = land carbon sink functions less well. Nitrogen overload from fertilizer kills lakes and the Baltic Sea, also a carbon sink.
And so on.
We urgently do need to get back into and then stay within all planetary boundaries. PV and wind turbines aren't enough to tackle the #PlanetaryEmergency 🙂

PIK director Johan Rockström was awarded the 2024 Tyler Prize for Environmental Achievement in a festive ceremony held in Potsdam! He received it for his advancement of the #planetaryboundary science & its importance and reach across the world - congrats!

The climate crisis is a poly-crisis and you can't solve it with the current carbon trading system, since that only moves the problem and the harm to other planetary boundries

Scientists warn that plastics & other pollutants are pushing past a #PlanetaryBoundary, even as #petrochemical comps increase #plastic production. 175 countries have said: ENOUGH. #PlasticsTreaty negotiations underway #INC1. I looked at the data needed to make it stick. @[email protected] @plasticpollution

Calling all #scienceHistory #PlasticPollution and #PlanetaryBoundary nerds!

I recorded a podcast with the lovely and knowledgeable @frankvonhippel, and we discussed everything from #plastics to #CFCs to #CigaretteButts. Have a listen!
