Critcisms of the energy budget model approach are that it is sensitive to uncertainties in observations and doesn't account for slow feedbacks between the atmosphere, deep oceans and ice sheets.

One issue that I have wondered about for some time is to what extent the paleoclimate record supports the distinction between slow - feedback and fast - feedback climate sensitivity.
Model studies for climate change between the Holocene and the Pliocene, when Earth was about 3 °C warmer, find that slow feedbacks due to changes of ice sheets and vegetation cover amplified the fast feedback climate response by 30 — 50 % [216].
As a result, the «feedback loop» of communication between the brain and the hormone glands slows down or becomes dormant, lowering the body's natural production.
These Interactive Areas allow feedback to the Slow Travel Classifieds and real - time interaction between users.
Proposed explanations for the discrepancy include ocean — atmosphere coupling that is too weak in models, insufficient energy cascades from smaller to larger spatial and temporal scales, or that global climate models do not consider slow climate feedbacks related to the carbon cycle or interactions between ice sheets and climate.
Equilibrium sensitivity, including slower surface albedo feedbacks, is 6 °C for doubled CO2 for the range of climate states between glacial conditions and ice - free Antarctica.»
Granted, it is «slow» right now, but the melting has been increasing quite substantially, and whereas the IPCC had been speaking in the neighborhood of a sea level increase of 50 cm, figures between one to two meters are becoming common as the result of observed changes, and with the nonlinear processes and resulting positive feedback, Jim Hansen has suggested that a sea level doubling per decade and increase of several meters (up to 5 m) by the end of the century is more realistic.
Granted, it is «slow» right now, but the melting has been increasing quite substantially, and whereas the IPCC had been speaking in the neighborhood of a sea level increase of 50 cm, figures between one to two meters are becoming common as the result of the observed higher rates since, and with the nonlinear processes and resulting positive feedback, Jim Hansen has suggested that a sea level doubling per decade and increase of several meters (up to 5 m) by the end of the century is more realistic.
This is important to allow capturing the two - way feedback between the atmosphere and the sea surface temperatures, for example when a tropical cyclone is slow moving it can cool the sea surface.
The distinction he draws between slow and fast feedbacks is fine and serves as a widely recognizable characterization of what he is describing.
Do many people make a specific distinction between fast and slow feedbacks as well as between transient and equilibrium sensitivity?
Model studies for climate change between the Holocene and the Pliocene, when Earth was about 3 °C warmer, find that slow feedbacks due to changes of ice sheets and vegetation cover amplified the fast feedback climate response by 30 — 50 % [216].
More care needs to be taken in defining and discussing fast and slow feedbacks, and the distinctions between them
Will the sensitivity of the atmosphere to the primary mechanism at the heart of El Niño — that is, feedback between the higher sea temperatures and slowing trade winds, leading to atmospheric convection over the central Pacific — continue in the future?
