Economists often assume that ecosystem and population dynamics are subject to convex, even linear processes. But research by ecosystem and population ecologists suggests that such processes are very often non-convex, for example a possible flip of the Gulf Stream due to fresh water intrusion from melting glaciers. This has dramatic implications for environmental and resource economics, since mistakes in management could prove more costly than imagined.
