The new official "Planetary Boundaries" graphic!
This is the update by the original authors: Johan Rockström, Will Steffen, Katherine Richardson - a group I was privileged to join with my team.
@W_Lucht Is there a source with more explanatory legends?
@W_Lucht this is major. i like the logarithmisch figure
@Bratananium
Glad to hear that! You wouldn't believe how long we discussed it ... whatever you do, it has pros and cons. For example, one can't compare the length of the wedges to each other, they each have their own topical metric (of how far that boundary has been transgressed). So we added these thin grey lines to indicate separation ... but I don't think many get that.
@W_Lucht
SFUBAR - allready lost the N
@W_Lucht all the ones still in the green are about to be obliterated by the space industry just fyi
@W_Lucht Interesting update, Wolfgang. Thanks for sharing. I was surprised to see OA still being considered in the safe operating space. Would you mind sharing who is the topical expert of this assessment?
@onecreativecat
Thanks! Corrected!!
@W_Lucht Just a minor question I've already asked before, but received no decisive answers so far: What's the name for this type of 'wedgy' chart you are using here? TIA.
@lorenzlm
I don't think it has a commonly used name.
@W_Lucht Not sure how to interpret it. Do the orange and red areas indicate stages we've already reached?
@anne_twain
Current status of control variables for all nine PBs. Green is the safe operating space (below the boundary). Yellow to red is the zone of increasing risk. Purple indicates the high-risk zone where interglacial Earth system conditions are transgressed with high confidence. Values for control variables are normalized so that the origin represents mean Holocene conditions and the planetary boundary lies at the same radius for all boundaries. Wedge lengths are scaled logarithmically.
Thanks @W_Lucht! What are the novel entities? - The paper mentions untested chemicals; spontaneously I thought an unprecedented phenomenon like "Living with Covid" (=systematically degrading people's immune systems or the human immunosphere over time) would fit as well.
@W_Lucht Honestly I was not a fan of the first articles because of the lack of quantitative info - but this is really a big step toward showing the potential of the framework as a tool! I really like how the new “Novel Entities” category is integrated - & as someone working on system-based environmental impact theory this looks like if EIA were properly quantified they could be included by industrial sector ?
@ecology_revised
It's very much true that the scientific foundations on which the framework builds - from knowledge synthesis to observation to modelling - has to be substantially strengthened and deepened going forward. Where we are at present is not yet what we think is needed, and could be done. That requires a coordinated major initiative from science. We'll be announcing something on Monday.
@ecology_revised
I think this paper is the best description to date of how perhaps to downscale boundaries to territories, organisations, groups or people:

@W_Lucht I’m looking forward to the news ! and thanks for the link I did not see that ref -
@W_Lucht Here the paper where the graphic comes from: https://www.science.org/doi/10.1126/sciadv.adh2458
