- First launched in 2009, the planetary boundaries framework is a science-based health check of the nine processes that keep our planet stable and resilient. The development of this framework, now a standard for sustainability science, was led by Johan Rockström. In his keynote presentation at Frontiers Forum Live 2023, Johan explained that humans are now the dominating force of change to the Earth system, and that we have a short window open to keep the planet in a Holocene-like interglacial state.
The planetary boundaries framework demonstrates that we're starting to see the loss of resilience that the Earth system needs to be able to correct itself, even if we do decarbonize rapidly and achieve our net zero goals. Johan outlined the latest progress on the development of the planetary boundaries framework and concluded that science has a fundamental role to play in the transformational, innovative and equitable, global sustainability transition that is required to ensure that we remain within a safe and just operating space for humanity and biodiversity on Earth.
Professor Johan Rockström is director of the Potsdam Institute for Climate Impact Research and was recently named one of Time's 100 most influential people of 2023. He's a global expert on sustainability issues and global water resources, and one of the most cited researchers in the world. Johan is additionally Chief Scientist of Conservation International and acts as an advisor on sustainable development issues at international meetings including the World Economic Forum, the United Nations Sustainable Development Solutions Network (SDSN), and the United Nations Framework Convention on Climate Change Conferences (UNFCCC).
Frontiers Forum Live showcases science-led solutions for healthy lives on a healthy planet. The event is held annually in Montreux, Switzerland and there are virtual sessions throughout the year. Find out more and watch previous sessions at forum.frontiersin.org/. - Věda a technologie
The apathy of the Human race in dealing with this crisis, will part of our epitaph... ei, this post has been up for over a month with only 394 "thumbs up" and only two comments. Great presentation and well researched information, thank you.....
Thank you Johan for you and your team’s work to develop the Planetary Boundary Framework and the current efforts to provide a status report. It moves the debate to beyond just climate and I am grateful for this.
On climate, it would seem that our current production of aerosols also needs to be highlighted and addressed in our policy development and strategies. Thank you again :)
Thank you Johan! You are a kind of science rock star to me with your clear and well founded presentation.
I love Johan and learn so much from his panels. I do wonder what the steps to turn the agricultural industry into a carbon sink would be. very ambitious
Great talk
Just Have A Think sent me.
Thx, for your work
Impressive presentation!
A better name for our current epoch would be The Petrocene.
A better name for climate change is terraforming.
It was a real lightbulb moment for me to hear the holocene described as an attractor within a state-space, realised by specific feedback loops provided by identifiable natural systems
Profoundly important synthesis of the science.
My concern is if (as seems likely) we breach the 1.5° guardrail during this now-unwinding El Niño phase, that self-reinforcing feedbacks will not relent & instead we will find ourselves stuck at 1.5 & quickening beyond that number - faster than expected.
Thank you for a brilliant eye opener
Excellent and deftly avoids discussing overpopulation
Excellent compliment to the Ecological Footprint.
Thank you for the video! Is the slideshow (with those great graphs etc) available for download?
Indeed, a great talk (👍). And to think the authors set upon this framework in 2009.
Time is wasting - if not already being planned, shouldn’t this be the topic of a Global Town Hall? Translate into all languages . . . for required viewing.
A piecemeal, market-based approach is not going to bring about the change that this presentation is calling for.
May we find the courage to act ✌️
It seems optimistic to believe we're once again staged presently to pass strong legislation and policy in the favor of climate change mitigation.
Despite the evidence and scientific data, the myriad of other international and more immediate national security concerns constantly in flux on earth typically take priority. I hope that we'll stay off each other's throats well enough to allow us as a species to allocate proper attention and funding towards these overarching catastrophic problems in time.
I adore what Johan stands for and articulates so brilliantly. JR for the EU presidency!
Surely when the dinosaurs lived temperatures where more than 2° higher right??
And if those high temperatures can kill a human which evolved to sweat to cool off and cloth to protect from the sun, I can imagine that many species might disappear from those heatwaves
One thing ALL of these talks miss is the impact of change on our agricultural systems. Weather chaos is going to considerably impede our ability to feed a planet. What going to happen to civilization (communities) when they can't feed themselves and water scarcity is common place (things we are beginning to see now)?
Whenever these talks focus on physical impacts they leave LOTS on the table that are not discussed. That is sad because this ends up being a very incomplete picture of what is coming down the road RIGHT NOW.
In short, this presentation is nothing more than an academic exercise that focuses on the physical earth.
One last comment. Why expound on carbon pricing on one hand and earlier in the presentation you say just plain stop? Carbon pricing would have been a good idea in the 80's and maybe the 90's. Now it is nothing but slowing down throwing wood on the bonfire that is earth.
good luck with natural sequestration when the forests are drying up and burning globally
Let's be real, GDP is hardly much of a source for capital investment for environ concerns presently. Corporate CEOs and boards are far more interested in stock buy backs, share holder increases, private jets, yachts, art, and vacations to the Bahamas. Additionally, 1.5 C is a pipe dream fantasy at this point. Likely we approach 1.8 ten years from now and exceed 2 C in less than 20 years. We are headed for catastrophic serial grain basket collapses on all continents. What's left of petroleum and gas will be expended in a race to decarbonize and mine and deploy ecars and transform the grid. Too little too late. The Wasteland is already etched in stone we just will not acknowledge it. Mitigation has been a complete failure. We need to start pouring resources into crop biotech, sea wall construction, precision fermentation, and solar management. Restoration of sensitive ecosystems is also imperative. But we will hardly do what is necessary because, yup, you guessed it: private jet vacation destinations and yachts are more important than ecosystem restoration.
