Strong, C., and G. Magnusdottir, 2010: The role of Rossby wave breaking in shaping the equilibrium atmospheric response to North Atlantic boundary forcing.

Not exact matches

The Hansen et al study (2004) on target atmospheric CO2 and climate sensitivity is quite clear on this topic: equilibrium responses would double the GCM - based estimates, with very little to be said about transient effects.

Stouffer, R.J., and S. Manabe, 2003: Equilibrium response of thermohaline circulation to large changes in atmospheric CO2 concentration.

Never mind the continuing increase in atmospheric CO2 — what happened to the 0.5 degree rise due to equilibrium response to recent levels of GHGs.

Refering to bands where optical thickness is constant over the interval of each band, if the atmospheric LW absorption is limited to some band (that doesn't cover all LW radiation), than increases in OLR in response to surface warming will occur outside that band, so OLR will drop within the band — there will still be some portion of stratospheric or near - TOA cooling that will be transient, but some will remain at full equilibrium.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

However, research has remained consistent with the IPCC range of 2 — 4.5 °C equilibrium warming in response to a doubling of atmospheric CO2.

A.) If I wanted to get a rough estimate of the equilibrium warming response to a tripling of the preindustrial atmospheric concentration of CO2eq (so 3 x 280 CO2eq ppm), I would just take my best sensitivity - per - doubling estimate on the bottom bar and multiply it by 1.5?

Each of these components, C1, C2 and C3, is then associated with some fraction of the emissions into the atmosphere, E, and a particular removal mechanism: where b3 (= 0.1) is a fixed constant representing the Revelle buffer factor, and b1 is a fixed constant such that b1 + b3 = 0.3 [11]; b1 represents the fraction of atmospheric CO2 that would remain in the atmosphere following an injection of carbon in the absence of the equilibrium response and ocean advection; b0 represents an adjustable time constant, the inverse of which is of order 200 years.

Seawater data collected by a Hydrolab DataSonde (Hach Company, Loveland, CO) since 2000 show that the ocean at this site has undergone a sustained decline in pH over the past decade [2] at a rate that is an order of magnitude greater than expected based on model predictions [13] and the equilibrium response to rising atmospheric CO2 concentration.

The statement which was made regarding atmospheric cooling, is from NASA, and not Columbia University: «To quantify climate change, researchers need to know the Transient Climate Response (TCR) and Equilibrium Climate Sensitivity (ECS) of Earth.

Changes in near - coastal circulation or biochemistry seem to be altering surface ocean pH more quickly than can be explained by an equilibrium response to the rising atmospheric CO2 concentration (Wootton and Pfister, 2012).

Quantifying the equilibrium response of global temperatures to an increase in atmospheric carbon dioxide concentrations is one of the cornerstones of climate research.

The equilibrium response of the control run (1950 atmospheric composition, CO2 approx. 310 ppm) and runs with successive CO2 doublings and halvings reveals that snowball Earth instability occurs just beyond three CO2 halvings.

Recently there have been some studies and comments by a few climate scientists that based on the slowed global surface warming over the past decade, estimates of the Earth's overall equilibrium climate sensitivity (the total amount of global surface warming in response to the increased greenhouse effect from a doubling of atmospheric CO2, including amplifying and dampening feedbacks) may be a bit too high.
