claimSystems diagrams and models can be used to represent the cause and effect of climate change, including feedback loops (positive or negative) and changes in the global energy balance.
claimEnergy imbalance in the climate system can lead to feedback loops, such as melting ice which reduces albedo, and ocean heat uptake, which further accelerate warming.
claimThe interaction of multiple tipping points creates complex feedback loops that complicate climate models and make it difficult to predict the speed or severity of climate change due to unexpected domino effects.
claimUncertainty in climate models arises from four primary factors: variability in future emissions and land-use changes (inputs), potential inaccuracies in indirect measurements (proxy data), the difficulty of predicting natural events like volcanic eruptions or solar activity (natural variability), and the complexity of modeling processes like ice-albedo or permafrost thawing (feedback loops).
Self-awareness, self-regulation, and self-transcendence (S-ART) frontiersin.org 2 facts
claimMotivation and intention function as a feedback system for self-schema maintenance, where sensory input is compared to a reference, and discrepancies feed back into frontal goal-oriented networks and pre-motor-action networks.
claimAttentional regulation occurs from a bottom-up direction, allowing cognitive resources to be conserved while non-conscious afferent-efferent systems interact with the environment in an adaptive feedback loop with top-down systems.

claimCortisol secretion is regulated by a complex feedback system where stress triggers the hypothalamus to release corticotropin-releasing factor (CRF), which stimulates the pituitary to release adrenocorticotropic hormone (ACTH), which in turn stimulates the adrenal glands to secrete cortisol.
The Problem of Hard and Easy Problems cambridge.org Mar 31, 2023 1 fact
referenceFeedback loops where downstream effects feed back into a mechanism can turn attempts to quantitatively model and predict the states and outcomes of that mechanism into a complex problem involving partial differential equations, as noted by Shmulevich and Aitchison (2009).

claimContinuous engagement in high-dopamine activities creates a feedback loop where the brain increases its neurochemical craving to continue the activity, making it more difficult to return to a low-dopamine state.
Energy Equity and Just Transitions understand-energy.stanford.edu 1 fact
claimFeedback loops in energy systems, such as policy incentives or taxes, regulate system behavior through mechanisms of self-correction or reinforcement.
