Would you expect the cloud feedback effect to damp this increase?

He also notes that it has a feedback effect, which it clearly does because heating of bodies of water increases evaporation, putting more WVP in the atmosphere, and increasing it's GH impact.

Where water vapor is important is as a feedback effect... whereby the warming of the atmosphere due to increased CO2 causes the «equilibrium» concentration of water vapor to increase and this then enhances the warming because of water vapor's absorption of infrared radiation.

Natural variability, internal variability, external forcing, internal forcing, feedback effect — they all require some self - consistent definition.

-- GHGs can work both as forcing and as feedback, the notion is clear, also that water vapour is a positive feedback effect — When water warms the amount of water vapour will increase, as will C02

And then of course, would the low level clouds be a negative or positive feedback effect on outbound LWIR.

The Arctic is warming up three times more quickly than the rest of the Earth, in part because of the reflectivity, or the albedo feedback effect, of ice.

There is no measurable feedback effect of a drop of 40 ppmv CO2 at the end of the Eemian,.....»

Water vapor, when it condenses in the Atmosphere, forms clouds that I and most other skeptics believe have a net negative feedback effect.

In this article, I provide a diagnosis and prescription for the IPCC: paradigm paralysis, caused by motivated reasoning, oversimplification, and consensus seeking; worsened and made permanent by a vicious positive feedback effect at the climate science - policy interface.

GH effect of CO2 is no more than 1 C. All other significant global warming is said to be from some positive feedback effect.

Other research suggests that higher temperatures could trigger a feedback effect whereby emissions from forests will increase due to reduced rainfall and increased incidence of fire and tree - killing pest outbreaks.

Jim D, can you post a link to the research which demonstrates the feedback effect from clouds is positive?

Undoubtedly there was a CO2 feedback effect.

Once an ice sheet starts to melt, the surface of the ice gradually decreases in altitude and becomes warmer, leading to yet more melting in a positive feedback effect.

Only when we have an INDEPENDENT method of calculating the the marginal CO2 effect on global T can we assign a value to the glacial - interglacial CO2 feedback effect.

For precisely the same core reason (apsidal precession) the opposite occurs in the southern hemisphere: less insolation at far southern latitudes, sea ice melting delayed, albedo increasing, less energy absorbed: growing sea ice: the ice albedo feedback effect acting negatively.

They can guess about no - feedback effect and all the feedbacks, but there is no correlation between the doublings of human emissions from fossil fuels [or slight rise of global CO2] to temperature.

Do you have any proof that anything you say here has anything to do with a «feedback effect» or is this just your opinion?

«This H2O negative - feedback effect on CO2 is ignored in models that assume that warm moist air does not rise and form sunlight - reflecting clouds, but remains as humid air near sea level, absorbing infrared radiation from the sun, and approximately doubling the temperature rises predicted from atmospheric CO2 increases.

There might be a slight positive feedback effect, but it's much less than other factors.

That is we measure both the no - feedback effect, AND the effect of all the feedbacks.

As I have pointed out in the «essay», what has happened (in an accelerating manner since 1246 CE) is that the insolation reaching far northern latitudes has increased during the first half of each year, and this should be anticipated to cause earlier and more - extensive spring melting of snow and ice, and therefore a progressively - earlier albedo reduction, and therefore more sunlight subsequently being absorbed across spring and summer: the ice albedo feedback effect acting positively (causing warming).

I explained in my essay in some detail, and several times, the ice albedo feedback effect, and gave an illustrative calculation.

Some skeptics ask, «If global warming has a positive feedback effect, then why don't we have runaway warming?

The impact from 1998 to today would be between -0.015 C to about -0.035 C depending on how much feedback effect you want to build in...

So it has a negative - feedback effect, not a positive - feedback effect.

In this article I present prima facie evidence that the ongoing natural increase in spring insolation occurring at high northern latitudes, coupled with the positive feedback effect of the resultant snow and ice loss reducing the region's mean albedo over summer, comprises just such a causative agency.

«I think this is a great model because it appears to require a significant GHG feedback effect from the CO2.

All told, I think this is a great model because it appears to require a significant GHG feedback effect from the CO2.

Without the elusive, unproven feedback effect there is no problem.

In the Arctic, one familiar feedback effect is sea ice albedo, which measures how well the Earth's surface reflects sunlight.

«Stratospheric water vapor has a positive climate feedback effect: a warming climate increases stratospheric water vapor, and the increased stratospheric water vapor enhances surface warming.

They don't explain at all why the data shows a feedback effect, or what the mechanism is that stops the positive feedback from being a runaway process (a frequent question by skeptics).

This change — reducing the amount of white, reflective ice surface — led to further warmth, in a feedback effect.

As I've demonstrated, some warming has to be attributed to the positive feedback effect of water vapour, however, you are right in saying that the trigger for past warming was (almost always) solar activity (or Milankovitch cycles).

It only becomes significant in the models by assuming that water vapor concentration increases in response to the slight warming produced by CO2 increases and therefore constitutes a powerful positive feedback effect which triples the effect of CO2 by itself.
