Sentences with phrase «natural feedback mechanism»

Such stability suggests some form of natural feedback mechanism that has compensated for far more severe changes in inputs than man - made CO2.

He says that most if not all our natural feedback mechanisms are now failing and working against us and it is absolutely vital that we act decisively NOW.

In the absence of the natural upregulation and downregulation of the TSH, the feedback mechanism regulating thyroid hormone levels may become inefficient with disuse.

The medication can suppress the normal production of cortisol (natural form of cortisone) in the body because of the feedback mechanism from high levels of the hormone in the bloodstream.

Cox et al. assumed that the same feedback mechanisms are involved in both natural variations and a climate change due to increased CO2.

This «climate sensitivity» not only depends on the direct effect of the GHGs themselves, but also on natural «climate feedback» mechanisms, particularly those due to clouds, water vapour, and snow cover.

Some modellers are now warning that feedback mechanisms in the natural environment which either accelerate or mitigate warming may be even more difficult to predict than previously assumed.

With this you then made your transition through to your final concept as follows, «And to return to the title of the post, I think that the debate should not be about feedback at all, it should be a debate about the types and the effects of the various natural homeostatic mechanisms.»

Judith — It seems possible that the PDO is not simply «natural variability» — that is, an unforced mode which adds «noise» to the temperature history — but is in fact a negative feedback mechanism.

There are certainly other natural mechanisms besides the ocean CO2 reservoir, and certainly other natural feedback loops between temperature and CO2.

They come up with all kinds of hypothetical feedback mechanisms involving more natural aerosol emissions in response to global warming: Dimethylsulfide from marine phytoplankton (although a very intriguing possibility, this has never been confirmed to be a significant feedback mechanism, and there is ample evidence to the contrary, which is omitted from the report), biological aerosols (idem), carbonyl sulfide (idem), nitrous oxide (idem), and iodocompounds (idem), about which they write the following: «Iodocompounds — created by marine algae — function as cloud condensation nuclei, which help create new clouds that reflect more incoming solar radiation back to space and thereby cool the planet.»

In particular: i) the emphasis on reconstructions of historical temperature records; ii) the over-sensitivity of climate models; iii) the exaggeration of positive feedback mechanisms and the opposite with respect to negative feedbacks; iv) the over-statement of second and Nth - order effects of warming on natural processes and society as «impacts»; v) the IPCC reports are not written exclusively by scientists, but in the case of WGII and WGIII especially, are, as has been discovered — by sceptics — written by academics from other disciplines, often without any remarkable expertise, and by activists, with particular agendas.

If this is natural, so if a «warming regime» (the word choice may indicate bias, by the way) is changed unforced into a cooling regime you may very have proven that a positive feedback mechanism due to water vapor is impossible.

As I will discuss in the section on feedback processes later, most well - regulated natural systems have feedback mechanisms that tend to keep trends in key variables from «running away.»

Is there some sort of a «natural thermostat» mechanism by which atmospheric water vapor content is regulated to prevent a long - term «positive feedback» from water vapor, as is assumed by all the IPCC climate models?

The question that this raises: Is there some sort of a «natural thermostat» mechanism by which atmospheric water vapor content is regulated to prevent a long - term «positive feedback» from water vapor, as is assumed by all the IPCC climate models?
