Climate change is only one of the planetary boundaries that have been crossed in terms of risk. It is important from a systems perspective to understand something of all nine. There is a brilliant TED talk done a few years ago – see the URL below. The TED talk is at: Johan Rockström: Let the environment guide our development | TED Talk and the updated URL is found below after the summary:
In September 2023, a team of scientists quantified, for the first time, all nine processes that regulate the stability and resilience of the Earth system.
These nine planetary boundaries were first proposed by former centre director Johan Rockström and a group of 28 internationally renowned scientists in 2009.
Since then, their framework has been revised several times.
Now the latest update not only quantified all boundaries, it also concludes that six of the nine boundaries have been transgressed.
