“Good Enough” tools

Avoiding the tip!
1. Elements can be identified which have the potential to tip.
(You can see other stable states and possible thresholds.)
2. Decisions taken within a “Political Time Horizon” can determine
what happens.
(There is still time to have an effect.)
3. The time to observe change plus the time to trigger it lie within an
“Ethical Time Horizon”.
(Events too far away have little chance of influencing today’s
decisions)
4. A significant number of people care about the consequences
should an element tip.
(A significant change in human welfare could occur or part of
the biosphere could be significantly disrupted.)

Agenda
• The State of the World and Australia

• The Choice
31
If we choose to lose!
“The phenomenon of overshoot and collapse – and the
possibility of global collapse – is still relevant and worthy of
study.
Global collapse triggered by ever growing emissions of
greenhouse gases is still conceivable in the first half of the 21st
century, because of the unfortunate combination of global
decision delays and self-reinforcing feedback in the climate
system.
Interestingly it may prove difficult to verify that global collapse
did take place—even if it did, and even after the fact.
Global collapse – defined as a situation where more than one
billion people lose one half of what they hold dear in less than
20 years – may well be hidden from the headlines and the
history books.
J.Randers/Futures 40 (2008) 853-864
32
If we choose to lose!
The 21st century is more likely to be described as a period of
intense local strife, institutional breakdown, regionalization and
general malaise. The root cause – humanity overstepping an
environmental limit – may well be lost in the clutter of historical
detail.
Global Collapse could remain fiction, even if it proved to be
fact.”
J.Randers/Futures 40 (2008) 853-864
33
If we choose to win!
We must understand and incorporate the concepts of resilience
thinking into our political, economic and social structures.
We must start at the highest level of the system in which we
might want to intervene.
On Climate Change the geopolitical system and the biophysical
system are intimately inter-related and should be seen as one!
Decisions must be taken within the “political time horizon”.
Enough people must care about a positive outcome in
order for politicians to have the courage to take action!
