Sentences with phrase «as a positive feedback system»

Not exact matches

Earth's crust is now understood as a complex system of fault surfaces, with rises and drops in stress reflecting the interplay of positive and negative feedbacks operating in the rupture process.
Isotopious @ 126 — So long as the system reponse is linear the internal complexity doesn't matter; the positive, i.e., enhancing, feedbacks remain postive and similarly for the negative ones.
The Department for Education said it had received positive feedback about the changes from many families, as many have found the new system more straightforward.

Multiple studies have demonstrated that organizations that prioritize a performance - management system that supports employees» professional growth outperform organizations that do not.25 Similar to all professionals, teachers need feedback and opportunities to develop and refine their practices.26 As their expertise increases, excellent teachers want to take on additional responsibilities and assume leadership roles within their schools.27 Unfortunately, few educators currently receive these kinds of opportunities for professional learning and growth.28 For example, well - developed, sustained professional learning communities, or PLCs, can serve as powerful levers to improve teaching practice and increase student achievement.29 When implemented poorly, however, PLCs result in little to no positive change in school performance.As their expertise increases, excellent teachers want to take on additional responsibilities and assume leadership roles within their schools.27 Unfortunately, few educators currently receive these kinds of opportunities for professional learning and growth.28 For example, well - developed, sustained professional learning communities, or PLCs, can serve as powerful levers to improve teaching practice and increase student achievement.29 When implemented poorly, however, PLCs result in little to no positive change in school performance.as powerful levers to improve teaching practice and increase student achievement.29 When implemented poorly, however, PLCs result in little to no positive change in school performance.30
The theory suggests that the system is pushed by greenhouse gas changes and warming — as well as solar intensity and Earth orbital eccentricities - past a threshold at which stage the components start to interact chaotically in multiple and changing negative and positive feedbacksas tremendous energies cascade through powerful subsystems.
Perhaps all of this newly freed up ice - cold water at the poles is temporarily acting as a negative feedback, but as it absorbs more of the solar radiation, over time, it will transform into what we rightly think: a predominately positive feedback system, rapidly intensifying the warming.
I am interested in the lags in the climate system and to see how the limit cycles may respond to minor amounts of positive feedback, such as that due to CO2 outgassing with temperature.
Negative feedbacks usually imply quiet conditions in a complex system, whereas positive feedbacks tend to lead to instabilities, often manifested as internal and spontaneous oscillations (see Figure 5).
Even in simple systems, small positive feedbacks can lead to stable situations as long as the «gain» factor is less than one (i.e. for every initial change in the quantity, the feedback change is less than the original one).
Complexity theory suggests that the system is pushed by such things as solar intensity and Earth orbital eccentricities — past a threshold at which stage the components start to interact chaotically in multiple and changing negative and positive feedbacksas tremendous energies cascade through powerful subsystems.
The system is best understood as having control variables, multiple negative and positive feedbacks and multiple emergent equilibria.
That is the nature of negative feedback systems, of which our climate is a prime example (note that «negative feedback» includes the Planck Response — in essence, the Stefan - Boltzmann response — and does not contradict the concept of «positive feedbacks» as amplifiers of CO2 - mediated temperature change, where «positive» is used to denote feedbacks other than the Planck Response).
As Lance Wallace points out, our climate system must have sufficient negative feedback to avoid positive feedback catastrophes.
As an engineer, I recognized such positive feedback as the hallmark of a fundamentally unstable system subject to «runaway», which is precisely what the likes of James Hansen were postulatinAs an engineer, I recognized such positive feedback as the hallmark of a fundamentally unstable system subject to «runaway», which is precisely what the likes of James Hansen were postulatinas the hallmark of a fundamentally unstable system subject to «runaway», which is precisely what the likes of James Hansen were postulating.
This warming is further magnified as a result of positive feedbacks in the climate system.
feedback loop, which will continue to hum along as an independent mechanism to keep the climate system at warmer temperatures until some new cooling event shuts down the positive feedback loop.
Climate sensitivity is somewhat uncertain as there are remaining scientific uncertainties about the magnitude of the positive and negative feedbacks in the climate system.
A deterministically chaotic system subject to control variables — such as CO2 — multiple positive and negative feedbacks and multiple equilibria.
I prefer to understand climate as a very long series of multiple frequencies non-linear positive and negative feedback oscillations of the coupled system of fluids that cover around 10 km below and 10 km over the average seal level of the Earth.
Hence, one gets a positive feedback whereby the warming of the arctic leads to ice melting which lowers the albedo of the earth and thereby leads to further warming of the arctic (and global climate system as a whole).
The theory suggests that the system is pushed by greenhouse gas changes and warming — as well as solar intensity and Earth orbital dynamics — past a threshold at which stage the components start to interact chaotically in multiple and changing negative and positive feedbacksas tremendous energies cascade through powerful subsystems.
Especially as the supporters of CAGW have yet to explain how they expect CO2 to drive positive feedbacks into water vapor and how they can ignore that water vapor is a negative feedback system.

The question remains: Will the well - documented natural negative feedbacks of the Earth's climate system cope with this added forcing or will the system spin out of control through positive feedbacks as postulated by mainstream climate science?
There is no modern - day instrumental record for estimating the potential long - term positive feedbacks in the climate system, i.e the slow feedbacks as Hansen refers to them.
We can think of the «process» here as the entire climate system, which contains many examples of both positive and negative feedback.
As for positive feedback, there are clearly lots of elements either positive or negative within a complex system, but clearly one has to look at both.
