Sentences with phrase «charney equilibrium climate sensitivity»

part of the utility is that Charney sensitivity, using only relatively rapid feedbacks, describes the climate response to an externally imposed forcing change on a particular timescale related to the heat capacity of the system (if the feedbacks were sufficiniently rapid and the heat capacity independent of time scale (it's not largely because of oceanic circulation), an imbalance would exponentially decay on the time scale of heat capacity * Charney equilibrium climate sensitivity.

captdallas2 @ 130 — To become more impressed by the estimate of about 3 K for Charney equilibrium climate sensitivity, read papers by Annan & Hargreaves.

Not exact matches

Charney (equilibrium) climate sensitivity is a (partial) indication of the system repsonse to instantly doubling CO2.

Global temperature change is about half that in Antarctica, so this equilibrium global climate sensitivity is 1.5 C (Wm ^ -2) ^ -1, double the fast - feedback (Charney) sensitivity.

Nonetheless, there is a tendency for similar equilibrium climate sensitivity ECS, especially using a Charney ECS defined as equilibrium global time average surface temperature change per unit tropopause - level forcing with stratospheric adjustment, for different types of forcings (CO2, CH4, solar) if the forcings are not too idiosyncratic.

Regarding ECS («equilibrium climate sensitivity»), I think there are difficulties estimating anything truly resembling a Charney - type ECS from data involving OHC uptake and forcing estimates, because these estimates are fraught with so many uncertainties, and because the values that are calculated, even if accurate, bear an uncertain relationship to how the climate would behave at equilibrium.

Equilibrium Climate Sensitivity, Charney Sensitivity, Greenhouse Effect, Atmospheric Carbon Dioxide, Fossil Fuel Emissions, Anthropogenic Global Warming, Human Caused Climate Change

The first attempt at a consensus estimate of the equilibrium sensitivity of climate to changes in atmospheric carbon dioxide concentrations appeared in 1979, in the U.S. National Research Council report of J.G. Charney and associates.
