Three recent scientific insights define our future in the 21st century, and reformulate the way we define sustainable development and our opportunities for meeting human needs in this crucial year when the global community will set a new post 2015 agenda and a new climate change agreement.
We have (1) become our own geological epoch, the Anthropocene, where humanity constitutes the largest force of change on the planet, (2) we now face rapidly rising risks of inducing tipping points that could disrupt the Earth system and modern civilisations with it, and (3) the fundamental insight that the Holocene, our “Edens garden” of environmental stability over past 10,700 years is our unique and desired planetary state, defining our biophysical safe operating space.
Combining these three scientific insights with our ethical responsibility of sharing equitably the remaining ecological space on Earth and respecting the right to development for all citizens, means that the world must develop within a safe and just operating space of a stable and resilient planet. Interestingly, this is not only humanity’s new grand challenge but also a grand opportunity.

He explains the situation were in with such clarity. I am encouraged to continue to do as much as I can personally and to continue voting for leaders who recognize the problem and work toward solutions.
Nice slide show, great graphs... now what are you going to do to reduce human population?.
Way he said albedo was one of the most swedish ways of saying it haha
1:42 " 7.2 billion people we" ?! It's close to 8 billion. Set to touch 12 by 2050. Infinite growth is not possible on a finite planet. Overshoot always leads to collapse.
Perhaps he should consider US three-letter agencies being more responsible for the Syrian civil war than a drought, and who’s to say extreme weather events aren’t at least in part a result of weather engineering.
No problem in problem in principle with the concept of planetary limits. Many have tried to quantify the limits. And all have failed. This signifies that so far the concept of planetary limits on humankind is philosophical rather than scientific. And thus more likely derived from personal worldview, whether pessimistic or optimistic.
