  2. Climate change feedbacks - Wikipedia

    en.wikipedia.org/wiki/Climate_change_feedbacks

    Positive feedbacks amplify global warming while negative feedbacks diminish it. [ 2 ]: 2233 Feedbacks influence both the amount of greenhouse gases in the atmosphere and the amount of temperature change that happens in response. While emissions are the forcing that causes climate change, feedbacks combine to control climate sensitivity to that ...

  3. Positive feedback - Wikipedia

    en.wikipedia.org/wiki/Positive_feedback

    Positive feedback occurs when a gene activates itself directly or indirectly via a double negative feedback loop. Genetic engineers have constructed and tested simple positive feedback networks in bacteria to demonstrate the concept of bistability. [28] A classic example of positive feedback is the lac operon in E. coli. Positive feedback plays ...

  4. Feedback - Wikipedia

    en.wikipedia.org/wiki/Feedback

    Positive feedback: If the signal feedback from output is in phase with the input signal, the feedback is called positive feedback. Negative feedback: If the signal feedback is out of phase by 180° with respect to the input signal, the feedback is called negative feedback. As an example of negative feedback, the diagram might represent a cruise ...

  5. Negative feedback - Wikipedia

    en.wikipedia.org/wiki/Negative_feedback

    A simple negative feedback system is descriptive, for example, of some electronic amplifiers. The feedback is negative if the loop gain AB is negative.. Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by ...

  6. Ice–albedo feedback - Wikipedia

    en.wikipedia.org/wiki/Ice–albedo_feedback

    Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy back to space than open water or any other land cover. [1] It occurs on Earth, and can also occur on exoplanets ...

  7. Cloud feedback - Wikipedia

    en.wikipedia.org/wiki/Cloud_feedback

    Cloud feedback is a type of climate change feedback, where the overall cloud frequency, height, and the relative fraction of the different types of clouds are altered due to climate change, and these changes then affect the Earth's energy balance. [1]: 2224 On their own, clouds are already an important part of the climate system, as they ...

  8. Causal loop diagram - Wikipedia

    en.wikipedia.org/wiki/Causal_loop_diagram

    A causal loop diagram (CLD) is a causal diagram that aids in visualizing how different variables in a system are causally interrelated. The diagram consists of a set of words and arrows. Causal loop diagrams are accompanied by a narrative which describes the causally closed situation the CLD describes. Closed loops, or causal feedback loops, in ...

  9. Intrapersonal communication - Wikipedia

    en.wikipedia.org/wiki/Intrapersonal_communication

    The two phenomena also influence each other in various ways. For example, the positive and negative feedback a person receives from other people shapes their self-concept or how they see themselves. This in turn has implications for how they talk to themselves in the form of positive or negative self-talk. [57]
