Despite all empirical evidence, IPCC scientists and bureaucrats will keep pushing the hotspot,
positive feedback hypothesis in order to continue their lucrative taxpayer funding.
Not exact matches
On the possibility of a changing cloud cover «forcing» global warming in recent times (assuming we can just ignore the CO2 physics and current literature on
feedbacks, since I don't see a contradiction between an internal radiative forcing and
positive feedbacks), one would have to explain a few things, like why the diurnal temperature gradient would decrease with a planet being warmed by decreased albedo... why the stratosphere should cool... why winters should warm faster than summers... essentially the same questions that come with the cosmic ray
hypothesis.
Since it has been substantially warmer than today many times in the past, without any evidence of runaway warming, the
hypothesis of runaway warming due to
positive feedbacks began to look distinctly unpromising.
I believe the reasons for the overstated
positive water vapor
feedback and the wrong sign cloud
feedback are both related to Lindzen's previously «discredited» adaptive iris
hypothesis about Tstorms in the tropics.
Per the IPCC's global warming
hypothesis, at the very top of the troposphere, above the equator region, is the location (12 km, 200hPa @ 20 ° N - 20 ° S) that triggers a
positive climate
feedback, which produces the mythical runaway, tipping point of accelerated, dangerous global warming, which of course is unequivocal and irrefutable, except when it isn't.
The AGW
hypothesis of tipping point, climate
positive feedback is proven false after decades of zero empirical evidence supporting it.
The more the climate's ironic
feedback loops thwart the climate alarmists, the more the alarmists rely instead upon the
positive feedback loops of groupthink to defend their dire
hypotheses.
Does not the
hypothesis of
positive feedback predict this?
By relying on a GCM, Stott's analysis omits the reaction of the ocean's heat capacity, and the strong,
positive and negative
feedbacks of cloud albedo, two of the omissions in GCMs that also serve to negate the affirmative
hypothesis.
This runaway effect that manmade climate change believers talk about comes from the
hypothesis that climate change
feedback mechanisms are
positive and the small warming we have experienced will lead to drastic increases in global temperature.
«Determining the strength and even the direction,
positive or negative, of the
feedbacks in the CLAW
hypothesis has proved one of the most challenging aspects of research into the role of the sulfur cycle on climate modification.»
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.
The consensus regarding the catastrophic global warming
hypothesis is completely reliant on a proposed
positive feedback producing runaway global warming that will destroy human civilization.
It sounds like they are going after the «all
feedbacks are
positive»
hypothesis that elevates CO2 forcing alone (+1 K) to the claimed +3 K for a doubling of pre-industrial levels of CO2.
«Our
hypothesis is that empathetic individuals are more responsive to a partner's needs, and thus initiate a
positive feedback cycle,» said Galinsky.
