Speleogenesis Earliest speleogenesis models were proposed by Dreybrodt (1990,1996) and Palmer (1991). These one-dimensional (1D) models allowed demonstrating the importance of non-linear dissolution processes and the existence of positive feedback loops while considering the evolution of a single frac...
Which of the following is the most likely consequence of the trend for the change in sea ice shown in the graph, creating a positive feedback loop in the Arctic? (A) Increasing albedo and increasing absorption of heat by the ocean (B) Increasing albedo and decreasing absorption of heat by...
The trigger could be, for example, a specific climate or energy policy or a breakthrough technology (such as cheap and effective energy storage). The point is that policies, institutions, and technologies reinforce each other in a positive feedback loop precipitating take-off and diffusion of su...
Using a mathematical model, we show that this occurs because pH and antibiotics modify the rates at which single cells produce and sense CSP and therefore the strength of the positive feedback loop coupling CSP detection to CSP production (Figs. 4 and 5). This environmental dependency does not...

Such positive feedback dynamics in the automobile system are emblematic of the ‘carbon lock-in’ of fossil fuel-based techno-institutional complexes [99], as well as of a form of infrastructure operation that results in unmanaged growing demand [83]. Historical accounts generally highlight the ...

When people interact in a social dilemma, their actions often have spillovers to their social, natural, and economic environment56,57,58,59. Changes in the environment may in turn modulate the characteristics of the social dilemma. One important example of such a feedback loop is the ‘tragedy...
