Try the #SystemDynamics tool used by UN #climate negotiators in an interactive webinar
Apply System Dynamics to climate change with the World Climate negotiation simulation by joining free webinars. Developed by Climate Interactive and MIT, World Climate is being used to engage thousands worldwide in cultivating leadership around climate change.
Free webinars are happening every week this fall in anticipation of the December United Nations (UN) talks in Paris.
The “How to Run A World Climate Event” webinar will provide an overview of the World Climate exercise and include an interactive demo of the System Dynamics model, C-ROADS, that is used to accompany the simulation to assess emission reductions. Drew Jones, co-director of Climate Interactive, and Ellie Johnston, Manager of the World Climate Project with be the presenters on this webinar.
A second webinar, titled “Interactive Simulation Tools for Assessing the Global Climate Deal” will explore the dynamics of C-ROADS and the latest assessment of pledges to the UN. More technical than the first webinar.
On August 20th, World Climate was featured as a climate education initiative at the White House. And the effort won the SD Society’s application award. Adoption of this transformative simulation tool is occurring worldwide. Learn what all the buzz about this systems thinking tool is all about.
The Forrester Seminar Series on System Dynamics
Professor Jay W. Forrester, founder of the field of System Dynamics, led a seminar series at the Sloan School of Management at MIT for PhD students in the fall of 1999 on the topic of System Dynamics. Each three-hour session covers a different stand-alone topic. Please preview Session D: Non-linearity. In this session, participants discuss linearity versus non-linearity, when is non-linearity important, how computers and simulation can play a part in better understanding, how a person can test a computer model, the importance of simplicity in a model, how to look for the high leverage policies in a model, are bigger models better, and the importance of generic structures and how to use them. The entire video series is available for purchase with an accompanying CD containing suggested readings for each session. Those who are applying System Dynamics in business and social situations will find the series useful in broadening and deepening their understanding of the field. For more information on the series, please visit the website. To purchase the series, please contact the System Dynamics Society at firstname.lastname@example.org.
Climate Interactive Announces Mock-UN Climate Negotiations Game at the White House
Climate Interactive announced the World Climate Project at a Back-to-School Climate Education Event at the White House.

Comments by Jay W. Forrester at the 2015 System Dynamics Conference
Conference attendees were delighted and honored to have Professor Jay W. Forrester, founder of the field of System Dynamics, as a special guest speaker at the conference. Jay gave a brief talk during the banquet at the 33rd International Conference of the System Dynamics Society. Speaking on July 21 in Cambridge, Massachusetts, he reflected on the first small gathering of people interested in System Dynamics, many years ago. He made observations about the current situation of System Dynamics, and he commented on its future, directions, and the mountains System Dynamicists can scale going forward. The banquet attendees thanked him by giving an enthusiastic standing ovation for several minutes. Anyone interested in Professor Forrester’s latest statements about the field he founded almost 60 years ago will find this recorded speech worth watching.
