From a systems perspective, the reason to stabilize our climate as soon as possible is to avoid the reinforcing biogeochemical feedback loops that could drive catastrophic, runaway climate change. We made our own causal loop diagram of many of the most important feedback loops. You can see it below. (Notice the big “balancing loop” […]
How does one build confidence in a system dynamics simulation like C-ROADS? Above you can see results from one important test that Tom Fiddaman of Ventana Systems did. Here’s what he did: From the published papers and online data, we made a graph of the “CO2 in the atmosphere” results from historical data and from […]
