The Dynamics of Climate Change:
Understanding and Influencing the Planet
Andrew Jones, Climate Interactive
XMILE Webinar – 8 October 2013
My Main Points
•
•
System Dynamics
• Powerful method
Climate Change
• Our insights
• Our contribution
• Need for
communications
across difference
We Use System Dynamics When:
1. Urgent, important problem
2. Disagreements or misunderstandings
about dynamics and cross-system
interactions
3. Ideally, data-rich space. Past and/or
future
Motivation 1: Difficulty Assessing Results
“...delegates [in Bonn] complained that their heads were
spinning as they were trying to understand the science
and assumptions underlying the increasing number of
proposals tabled for Annex I countries’ emission reduction
ranges.”
“They all seem to use
different base years
and assumptions…: how
can we make any sense
of them?”

C-ROADS Scientific Review Panel
• “C-ROADS… This very rapid simulation model
reproduces the response properties of state-of-the-art
three dimensional climate models very well … and
with sufficient precision to provide useful information
for its intended audience.”
• Dr. Robert Watson - Department for Environment, Food and Rural
Affairs (DEFRA) and former chair, IPCC -- Panel Chair
• Dr. Eric Beinhocker - McKinsey Global Institute
• Dr. Klaus Hasselmann - Max-Planck Institut für Meteorologie
• Dr. David Lane - London School of Economics
• Dr. Jorgen Randers - Norwegian School of Management BI

“I have to tell you —
C-ROADS works, it is
important, and it is
already getting broad
dissemination, ... I used
it!”
Senator John Kerry
