Sentences with phrase «strong negative feedback»

Strong negative feedback in any system leads to linear dependence of system's output on its input.
In this particular environment, it doesn't look like there are strong negative feedbacks on erosion rates because the material appears to be simply too fine - grained and ice - rich to be redeposited locally and form barriers, bars, etc..
Expectation of small but positive CO2 - greenhouse warming is consistent with his claims of strong negative feedbacks by upper tropospheric water vapor or cirrus clouds which would lose sense without initial warming in the global tropics.
These observations led Spencer and Braswell to conclude that alpha really should be 6 W / m ^ 2 / °C or more, indicating very strong negative feedback.
(1) How does he reconcile his belief about the climate being so stable... i.e., having strong negative feedbacks... with the ice age — interglacial oscillations?
Because plants in turn, in the process of photosynthesis, convert CO2 into oxygen, it is thus sometimes argued that such «co2 fertilization» could potentially provide a strong negative feedback on changing CO2 concentrations.
I'm not even an amateur climate scientist, but my logic tells me that if clouds have a stronger negative feedback in the Arctic, and I know (from news) the Arctic is warming faster than other areas, then it seems «forcing GHGs» (CO2, etc) may have a strong sensitivity than suggested, but this is suppressed by the cloud effect.
Several models see a positive feedback of clouds when the temperatures increase, but this seems to be wrong, at least in the tropics and the Arctic, where clouds form a strong negative feedback.
RE # 24, Ferdinand you state, «Several models see a positive feedback of clouds when the temperatures increase, but this seems to be wrong, at least in the tropics and the Arctic, where clouds form a strong negative feedback
Your correspondent effectively claims that the water vapour produces a strong negative feedback (in whatever way; who cares) reducing total sensitivity.
[T] here's no evidence that clouds are a strong negative feedback that will keep things under control.
Higher temperatures aloft imply a stronger negative feedback -LRB-?)
The net response is -0.8, which is a very strong negative feedback...
If the iris provided a strong negative feedback, then we would expect to see it in response to short - term climate fluctuations.
Second, that Lindzen is correct and that there is a strong negative feedback effect from the clouds in the tropics, which prevents the sea surface temperatures from changing there.
More clouds, higher local albedo, is a strong negative feedback.
The latter gives rise to a strong negative feedback between the surface temperature Ts and the temperature of «absolutely black body» Tbb, which is determined by the solar radiation S reaching the Earth's surface at its distance from the Sun.
These Atmospheric Heat Pipes produce a very strong negative feedback.
This means there are strong negative feedback mechanisms.
Stabilization of ca at the lower limit of 200 — 250 ppm during the past 24 Myr appears to result from a strong negative feedback in the form of attenuation of silicate rock weathering as terrestrial vegetation approaches CO2 starvation [Pagani et al., 2009].
As a result there is a strong negative feedback which would lead to global cooling.
