Sentences with phrase «climate bifurcation point»

Here we propose that increasing variablility within the past million yearsmay indicate that the climate system was approaching a second climate bifurcation point, after which it would transition again to a new stable state characterized by permanent mid-latitude Northern Hemisphere glaciation.

Not exact matches

The proximity of the present - day climate to the Stommel bifurcation point, beyond which North Atlantic Deep Water formation can not be sustained, varies from less than 0.1 Sv to over 0.5 Sv.

A concern with «large» climate changes (i.e., on the scale of snowball Earths or runaway greenhouses) is that there's bifurcation (loosely, tipping points) in the system.

If a frequency of sites spatially and of data collection over time can produce enough dynamically significant data points to satisfy the requirements of Chaos (eg, antialiasing, bifurcation), then we can know just how badly we are measuring the climate, and whether some currently ontic variability is really aleatory, or may be semi-deterministic in some spans and scales if only we have enough granularity in our sampling.

Tipping points in open systems: bifurcation, noise - induced and rate - dependent examples in the climate system

As shown in Sect. 2.2, this concern was bolstered by the possibility of a huge, highly nonlinear temperature drop if the climate system reached the upper - left bifurcation point of Fig. 1.

I usually add the postscript that dynamical systems theory implies extreme climate sensitivity near points of chaotic bifurcation — suggesting that changing the composition of the atmosphere may not be entirely risk free.
