Sentences with phrase «called feedback effects»

Well, it has to do with something called feedback effects.

Not exact matches

This positive feedback phenomenon, called the runaway albedo effect, would eventually lead to a single dominating ice cap, like the one observed on Pluto.
When I, with some colleagues at NASA, attempted to determine how clouds behave under varying temperatures, we discovered what we called an «Iris Effect,» wherein upper - level cirrus clouds contracted with increased temperature, providing a very strong negative climate feedback sufficient to greatly reduce the response to increasing CO2.
The most remarkable sonic manifestation was when the acoustical mixture of the bird calls and speaker feedback generated a heterodyne effect, a phenomenon that created phantom twitterings that seemed to originate inside my head and swirl around it like a localized tornado of sound.
In the original article Angela did write: «This effect, called the permafrost carbon feedback, is not present in the global climate change models used to estimate how warm the earth could get over the next century.»
This effect, called the permafrost carbon feedback, is not present in the global climate change models used to estimate how warm the earth could get over the next century.
Hansen seems to argue for a maximum rate of SLR, under BAU forcing, of at least 4 - 5 meters per century, somewhere in the coming centuries (including a negative feedback he calls the «ice berg cooling effect»).
However both do in fact force global temperature, therefore both could be called forcings and the greenhouse effect of water vapour would then be a positive feedback forcing.
It says this would be what's sometimes called «a global tipping point,» in which many amplifying feedbacks around the world produce a cumulative effect in which Earth enters a «change in state, carried by its own internal dynamics.»
This vicious cycle is called a positive feedback, and is believed to add considerably to the basic no - feedback greenhouse effect attributable to CO2.
''... the warming is only missing if one believes computer models where so - called feedbacks involving water vapor and clouds greatly amplify the small effect of CO2.»
The presence of feedback effects and tipping points calls into question some of the most fundamental assumptions of climate change negotiations, including the belief that we can «overshoot» to, say, 550 ppm and then work back to 450 ppm (the path advocated in the Stern and Garnaut reports), that greenhouse gas concentrations in the atmosphere can be stabilised at some level, and the belief that we can adapt to some given degree of warming.
One important determinant of how much climate will change is the effect of so - called «feedbacks» in the climate system, which can either dampen or amplify the initial effect of human influences on temperature.
The study suggests this so - called «CO2 fertilization effect» may also contribute to a stabilizing feedback in the climate system as increased biomass production and organic deposition in marshes sequester larger amounts of carbon dioxide.
When I, with some colleagues at NASA, attempted to determine how clouds behave under varying temperatures, we discovered what we called an «Iris Effect,» wherein upper - level cirrus clouds contracted with increased temperature, providing a very strong negative climate feedback sufficient to greatly reduce the response to increasing CO2.
Another example is the so - called feedback mechanisms, which are introduced to amplify an effect which is not marginal but does not exist at all.
Actually I think the claim is that CO2 warming (but mysteriously not «natural» warming) triggers other positive feedbacks causing a runaway effect (I won't call it «greenhouse» because that's a misnomer).
It's all as it was in those happy carefree days of 2009 and before, BC (yes, Before Cli **** ga **) as we call it now, when the MSM would happily «highlight the most alarmist aspects and downplay any mention of uncertainty» (Zorita), when no doubts were allowed, or should I say expressed, about the holy trilogy of WG1, 2, and 3 — how certain it was that the well - accepted theory of ghg effect, and the impacts thereof, would lead to a Copenhagen / Kyoto utopia of global cooperation, and that the IPCC was cool (whoops, «the request for more research about the social dynamics of the IPCC, of positive feedbacks as described by Judith, is meaningful for me» (von Storch).)
Some of these so - called feedbacks amplify the effects of changes that are imposed; others reduce them.
Motivated by findings that major components of so - called cloud «feedbacks» are best understood as rapid responses to CO2 forcing (Gregory and Webb in J Clim 21:58 — 71, 2008), the top of atmosphere (TOA) radiative effects from forcing, and the subsequent responses to global surface temperature changes from all «atmospheric feedbacks» (water vapour, lapse rate, surface albedo, «surface temperature» and cloud) are examined in detail in a General Circulation Model.
Brian's latest paper (with colleagues Tim Cronin from MIT and Cecilia Bitz from UW) is called «Ice Caps and Ice Belts: the effects of obliquity on ice - albedo feedback».
