Sentences with phrase «feedback processes caused»

The model considers all relevant feedback processes caused by changes of water vapour, lapse - rate, surface albedo or convection and evaporation.

-- In his calculations of the GE, he realized the important positive feedback process caused by concomitant changes in water vapor (4)....»

Chuckles Here is a cut and paste from Wiki; «Edelman integrates the DCH hypothesis into Neural Darwinism, in which metastable interactions in the thalamocortical region cause a process of selectionism through re-entry, a host of internal feedback loops.

Every degree of warming caused directly by CO2 is amplified by feedback processes.

Every degree of warming caused directly by CO2 is amplified by feedback processes that could drive temperatures much higher

«Some feedback loop or other processes that aren't accounted for in these models — the same ones used by the IPCC for current best estimates of 21st Century warming — caused a substantial portion of the warming that occurred during the PETM (Palaeocene - Eocene thermal maximum of 55 million years ago)», oceanographer Gerald Dickens, a professor of Earth science at Rice University and study co-author said.

Both cause temperature change so both will play a role in any future water vapour feedback process that is dependent on temperature.

For example, Mr. Mislevy pointed to diagnostic systems now used in computer - based programs such as Carnegie Learning and Khan Academy, in which students work through individual topics at their own pace, taking brief tests of their mastery along the way, with feedback delivered to the student and teacher on individual processes or misconceptions that cause the student problems.

However there is also yet another sense of the word, that I want to explore, at least speculatively, for a moment, in relation to Blannin's work and that's the sense of «system» used in cybernetics, where a central concept is that of «feedback», the process in which information about the past or present influences the same phenomenon in the present or future, forming a chain of cause - and - effect, a circuit or loop: output becomes input.

For example, if the Earth got cold enough, the encroachment of snow and ice toward low latitudes (where they have more sunlight to reflect per unit area), depending on the meridional temperature gradient, could become a runaway feedback — any little forcing that causes some cooling will cause an expansion of snow and ice toward lower latitudes sufficient to cause so much cooling that the process never reaches a new equilibrium — until the snow and ice reach the equator from both sides, at which point there is no more area for snow and ice to expand into.

The function of the DNA was not to produce proteins or regulate or translate them, but rather the nucleotide function was simply to provide an electrical feedback to convection processes that occur w / cirrus clouds that can trap heat, compress air and cause rain over ambient, lifeless winds and climate inputs.

The implication is that any process that does NOT add or subtract external energy to change the temperature, will by itself cause a conductive, convective or even a radiative feedback, that will result in no change in the temperature.

We conclude that in addition to direct CO2 forcing, other processes and / or feedbacks that are hitherto unknown must have caused a substantial portion of the warming during the Paleocene — Eocene Thermal Maximum.

When caused by land use changes it is a forcing factor, but in natural processes I think it is more of a feedback than a root cause of changes.

So that the median lines are the shared pathway of the EMF that is controllably shunted out of the chemical reaction to allow the flexible shifts in efficiency needed to prevent uncontrolled runaway feedback or disease processes that cause death.

Indeed the ENSO process itself may well be a negative feedback working against the forces (varying rates of energy transfer) that caused the air circulation changes in the first place.

AGW is a hypothesis which says that we are currently experiencing unusual warming of the Earth, that it is caused by excess CO2 produced by man, acting through a feedback process, and that it will continue to increase to create high temperatures which will be of net disadvantage to humankind.

A process involving «positive feedback» causes the warming to fuel itself, until it reaches a point that finally tips the climate pattern over.

In light of trends showing a likely 3 °C or more global temperature rise by the end of this century (a figure that could become much higher if all feedback processes, such as changes of sea ice and water vapor, are taken into account) that could result in sea level rises ranging from 20 to 59 cm (again a conservative estimation), Hansen believes it is critical for scientists in the field to speak out about the consequences and rebuke the spin offered by pundits who «have denigrated suggestions that business - as - usual greenhouse gas emissions may cause a sea level rise of the order of meters.»

They have, in effect, caused a positive feedback loop: the more soil is exposed to sunlight as a result of trees burning, the speedier the decomposition process and the more carbon dioxide is released.

I put «forcing» in quotes because the actual phenomena undoubtedly included internal climate processes in addition to imposed perturbations, but for these purposes, what seems most relevant is that all relevant processes were likely to invoke similar feedbacks over the long term, given that climate feedbacks are basically a response to a temperature change rather than to the cause of the change.

The program includes (a) title screen and login, introduction, and consent to use the program; (b) assessment of demographics; (c) assessment and feedback on different types of bullying experienced and perpetrated in the past year, whether they happened in the past month, and whether they caused fear; (d) for participants experiencing or perpetrating physical bullying or multiple episodes of emotional bullying, or who are experiencing fear: assessment and feedback on help seeking; (e) for all participants: assessment and feedback on six healthy relationship skills, including step - by - step guidance on and videos demonstrating two skills the participant has been using the least; (f) assessment and feedback on stage of change for using healthy relationship skills; (g) assessment and feedback on up to five TTM stage - matched principles and processes of change for using healthy relationship skills; encouragement to increase use of stage - matched principles of change the participant is not using enough; (h) assessment and feedback on level of alcohol use and its relationship to bullying and peer violence; (i) assessment and feedback on readiness to offer help to others who are victims or perpetrators of bullying; and (j) assessment and feedback on readiness to seek help if a victim or perpetrator of bullying.
