Sentences with phrase «strong positive feedback»

What if the climate is, unlike nearly every other long - term stable natural process, dominated by strong positive feedbacks?

The ice - albedo feedback is a very strong positive feedback that has been included in climate models since the 1970s.

The game received strong positive feedback and sold over 125,000 copies, encouraging the development of a bigger, better sequel.

The essential thing about the HCV is that natural negative feedbacks to draw down CO2 are being overwhelmed, and certain potentially very strong positive feedbacks seem to be kicking into high gear.

A future strong positive feedback from the carbon cycle, on the other hand, could add as much CO2 to the atmosphere as humans have, leading to temperature increases well beyond the International Panel on Climate Change's (IPCC) upper limits.

For reference, Spencer indicates that the climate models the IPCC uses to make temperature projections (and which incorporate fairly strong positive feedback) have alpha values of 0.9 - 1.9 W / m ^ 2 / °C.

For example, the models that predict up to 4 - 5C warming this century do so because they predict strong positive feedbacks from clouds and water vapour.

Because of its large seasonal variability and distinctive physical properties, snow plays a major role in the climate system through strong positive feedbacks related to albedo [e.g., Groisman et al., 1994a] and other weaker feedbacks related to moisture storage, latent heat, and insulation of the underlying surface [Stieglitz et al., 2003].

The early returns on one of the first law firm iPhone apps are in, with law firm Morrison & Foerster reporting that it is getting strong positive feedback from clients on the still - novel initiative.

Following a roadshow at the Pirate Summit in Cologne, Germany, ICONOMI gained strong positive feedback from decentralised economy startup colleagues, and one day later ICO topped $ 4 million and more than 1500 investors.

The study claims to have measured feedback, and have found feedback to temperature changes in the natural climate system to be negative — opposite of the assumption of strong positive feedback in climate models.

However the traditional view of a weak inherent climate sensitivity boosted by strong positive feedback from water vapour depends on the analysis framework; a valid alternative yields stronger intrinsic sensitivity, with a weak net clear - sky feedback.

but it is a second, unproven theory of strong positive feedbacks in the climate that causes the hypothesized catastrophe.

'' The oscillations in global mean temp over the last 11,000 years are not compatible with a strong positive feedback to temperature increase at the higher temperatures ``

And I would like to see us avoid 1000 ppm if at all possible — including the strong positive feedback from the carbon cycle itself.

A strong positive feedback mechanism is the accompanying increase of moisture, which is an even more powerful absorber of terrestrial radiation.

Chaos is just one state of a dynamical system when there is strong positive feedback.

Ice sheets have strong positive feedbacks, so I wouldn't be surprised if they melt faster and faster as time passes.

Strong positive feedbacks to the initial regional and seasonal orbital forcing are necessary to account for the eventual * global * glacial / interglacial climate shift.

With sufficient warming (around 4 - 8 times present CO2 concentration), Sc and Sc - over-Cu clouds collapse to Cu, implying a strong positive feedback of these low clouds on warming.
