Sentences with phrase «warming feedbacks thus»

With the theory of positive warming feedbacks thus neatly de-bunked, in a sane world we would see the end of cagw hysteria.

Not exact matches

Sea ice reflects most of the sun's energy, he explained, whereas the open ocean absorbs more energy, and thus the disappearance of sea ice triggers even more warming, in a positive - feedback loop called albedo.
These time scales are within the lifetime of anthropogenic CO2, and thus these feedbacks must be considered in estimating the dangerous level of global warming.
By this, I imply that some sort of negative feedback may prevent the planet from persistent warming, thus making «global warming» innacurate.
Since OHC uptake efficiency associated with surface warming is low compared with the rate of radiative restoring (increase in energy loss to space as specified by the climate feedback parameter), an important internal contribution must lead to a loss rather than a gain of ocean heat; thus the observation of OHC increase requires a dominant role for external forcing.
The cloud cover are likely not a forcing and thus a cause of warming but more likely a positive warming feedback.
(This doesn't include any solar - heating (albedo, etc.) feedbacks, which is necessary for a direct comparison; the GHE warming of about 33 K is only the effect of the atmopheric LW optical thickness, and thus doesn't include any feedbacks on solar heating)
[Response: That is a positive feedback that acted during ice age cycles: when it got warmer at the end of an ice age, this led to release of stored CO2 from the deep ocean, thus raising atmospheric CO2 levels.
It is easy to see why this feedback amplifies the climate change, because reduction of ice sheet size due to warming exposes a darker surface, which absorbs more sunlight, thus causing more warming.
Thus one would expect that that the warming models without feedback are better established and agreed to than those with feedback.
Through horizontal averaging, variations of water vapor and temperature that are related to the horizontal transport by the large - scale circulation will be largely removed, and thus the water vapor and temperature relationship obtained is more indicative of the property of moist convection, and is thus more relevant to the issue of water vapor feedback in global warming.
As more ocean is exposed, this can trigger a potentially dangerous mechanism of positive feedback, whereby less light is reflected, causing further warming and thus more ice to melt.
Thus there is no positive feedback upon which the IPCC stakes their claim that any carbon dioxide warming will be magnified.
According to the ice - albedo feedback mechanism as the Earth warms more ground and water would be uncovered which would absorb a higher proportion of the incoming solar radiation thus raising the temperature and melting more ice and snow.
But, if the atmosphere in the polar regions warms there will be more evaporation and thus a postive feedback from greenhouse effect of increased water vapor.
Thus, observations point to a positive low - cloud feedback on warming.
Even IPCC admitted it ignored multiple positive feedback loops that are sure to drive up temperatures, thus their warming predictions are fatally flawed and bring a false sense of security
As I've understood it from McGribben's explanation back in» 89, the tipping point occurs when the combined CO2e output of all feedbacks exceeds the carbon sinks» capacity, after which their outputs are inevitably adding to airborne GHG stocks and warming and are thus effectively self - reinforcing.
Under such a response, for uniform warming, the largest fractional change in water vapour, and thus the largest contribution to the feedback, occurs in the upper troposphere.
So we have the peculiar situation that both of these approaches try to claim that climate sensitivity is small, but the NIPCC approach is to claim that aerosol forcing is very large (thus providing a negative feedback to warming), whereas the Lindzen approach is to claim that aerosol forcing is very small (thus necessitating a small sensitivity to explain the observed warming so far).
Regarding that last point, consensus climate science has proposed a hypothesis on the claim that climate physics dictates that rising atmospheric CO2 levels will warm the atmosphere substantially, thus causing a positive feedback loop, which will then continuously accelerate warming until a tipping point of runaway temperatures take place, turning Earth into the next Venus.
Authors conclude from this and other evidence from process models that warmer climates may enhance tropical forest release of CO2, thus accelerating atmospheric CO2 accumulation through a positive feedback.
Then consider that whenever the number of photons does decrease (every day after the peak at noon) that the number of GHE interactions MUST also decrease, and that the number of unused GHGs (in the GHE process) MUST increase, thus establishing that there is AN EXCESS of GHGs over those used in the GHE process, and therefore ALL of the GHGs generated (either by man as CO2, or as WV by feedback) do NOT necessarily have to be in use to create more GHE warming.
Ferdinand, in 42 you wrote: «Thus it is difficult, if not impossible, to say what is attributable to GHG forcing (with feedbacks) and what the part of solar forcing (with feedbacks) in the amplified Arctic warming is».
Thus, sea ice has melted at an unprecedented rate and is now caught in a vicious cycle known as the ice - albedo feedback: as sea ice retreats, sunshine that would have been reflected into space by the bright white ice is instead absorbed by the ocean, causing waters to warm and melt even more ice.
They show that long - term acclimatization or adaptation to warm and acidified conditions could change or even reverse the negative calcification responses observed in short - term studies, and thus alter feedbacks to the global carbon cycle.
Changes in cloudiness appear to play a negligible role in observed Arctic darkening, thus reducing the possibility of Arctic cloud albedo feedbacks mitigating future Arctic warming.
Thus, there is a positive feedback between warming, snow aging, increased solar absorption, and reduced albedo.
None taken, I've been insulted by experts everywhere from Tamino to Deltoid; as for feedback from clouds I think I said clouds were a moderator [sic] and this can be contrary as my night example shows; that is, clouds at night warm whereas clouds at day cool; as for Professor Pinker, my friend Steve Short summed up her findings and cloud feedback thus:
