The findings suggest that effective new greenhouse gas controls could help lessen the effects of climate change on the release of carbon from soils of the northern permafrost region and therefore decrease the potential for a positive feedback of permafrost carbon release on climate warming.

Mr Stevenson said there has been positive feedback from families who are much happier with the flexibility and control they now have over their accounts and bookings.

If we can reduce GHGs enough (slow down GW), we may be able to avoid triggering positive feedbacks that we may not have any control over.

Ocean heat content is ultimately controlled by a number of complicating factors including positive and negative forcings and feedbacks dealing with clouds, water vapor, and also CO2.

We don't know that anthropogenic global warming will be limited before the system goes into runaway positive feedback driven by melting methane hydrates we can't control.

People often conclude that the existence of positive feedbacks must imply «runaway» effects i.e. the system spiralling out of control.

What we have right now (in my view) is an opportunity to actually control things and prevent both the positive feedback being enough to lead to rapid temperature growth, and the negative feedback being enough to cause an ice age.

I think some of the fear arises from the perception that the positive feedbacks, once started, would take on a life of their own — so to speak — and would not lend themselves to being easily controlled by human countermeasures.

In short, whatever the initial climate sensitivity is to a doubling of CO2, I just can't buy off on this positive feedback loop idea that says that temperatures are going to spin out of control once we pass over some «tipping point» that only seems to exists in some scientist's theoretical model.

The theory of climate shifts suggests that there are control variables and multiple positive and negative feedbacks in a complex dynamical system.

Conceptually — small changes in conditions precipitate non-linear responses in the system and the system shifts into a «new» state that is either warmer or cooler by amounts that, because of multiple negative and positive feedbacks, bear no linear relationships to the original control variable.

The system is best understood as having control variables, multiple negative and positive feedbacks and multiple emergent equilibria.

Thus like previous IPCC reports AR5 fails to include even the track records of the acceleration of those six potentially major non-linear positive feedbacks that scientists in the field observe to be active, let alone including any rational estimate of their combined potential to offset society's efforts at emissions control.

Positive feedback may be controlled by signals in the system being filtered, damped, or limited, or it can be cancelled or reduced by adding negative feedback.

A deterministically chaotic system subject to control variables — such as CO2 — multiple positive and negative feedbacks and multiple equilibria.

However the positive feedback driven out - of - control warming predicted by the CAGW is just delusional.

There are plenty of arguments against existence of positive feedback, the workof Drs. Lindzen and Spencer, paleoclimatic data and the fact that any system controlled by positive feedback is inherently unstable.

If the system is dominated by positive feedbacks, instead of negative ones, then it would have to spin out of control because feedbacks would beget even more feedbacks.

While biological systems, which may have positive feedback between various subsystems (with on / off switches to bound the response), are often control systems, energy - conserving natural systems don't operate that way.

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?

If further computations show that such a temperature ceiling is insufficient to control the positive feedbacks, then some form of geo - engineering might be required.

There is confusion based on the fact that when most climate scientists talk about a net positive feedback, they do not mean that in the same sense that it is used in systems theory (or control theory or whatever you want to call it).

Appreciating the fact that the customer is our finest asset, I ensure the development and installation of quality control programs, policies and procedures that will eventually benefit the company through positive customer feedback and recurring business.
