However, we must include slow feedbacks in projections of warming for the 21st century and beyond.

But perhaps you could eventually get there with slow feedbacks, I don't know.

In contrast, global warming of 2 °C or more is likely to bring slow feedbacks into play.

There is still much research to be done to include slow feedbacks and related effects.

First, most climate simulations, including ours above and those of IPCC [1], do not include slow feedbacks such as reduction of ice sheet size with global warming or release of greenhouse gases from thawing tundra.

Factoring in slow feedbacks from ice and vegetation changes would generate a significantly higher ECS, likely in the 4 to 6 C (7.2 to 10.8 F) range, the paper notes.

AR4 specifically excluded Greenland and Antarctica ice sheet melting, due to the uncertainties about ice flow dynamics, and also specifically excluded slow feedbacks, also due to the uncertainties involved.

Some climate scientists, including James E. Hansen, former head of the nasa Goddard Institute for Space Studies, say we must also consider slower feedbacks such as changes in the continental ice sheets.

Climate model studies and empirical analyses of paleoclimate data can provide estimates of the amplification of climate sensitivity caused by slow feedbacks, excluding the singular mechanisms that caused the hyperthermal events.

Paleoclimate data also provide quantitative information about how nominally slow feedback processes amplify climate sensitivity [51]--[52], [54]--[56], which also is important to our analyses.

These same slow feedbacks are estimated to amplify climate sensitivity by almost a factor of two for the climate change between the Holocene and the nearly ice - free climate state that existed 35 million years ago [54].

Thus when they make projections of 3 C per doubling, this is not taking into account slow feedbacks — which (according to Hansen's analysis) double the long term climate sensitivity.

«I think part of the reason slow feedbacks weren't included [in previous IPCC reports] was that they were assumed to be too slow to be relevant to human - induced climate change,» said Michael Previdi, lead author of the report.

The extra mediation slows the feedback loop and leads to a remote, anemic experience.

Yet, our National Research Council Climate Stabilization Targets report points out that some of the most dramatic climate changes will endure for tens of thousands of years, with slow feedbacks providing some of the more catastrophic possibilities.

The principal slow feedback is the area of Earth covered by ice sheets.

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.

This should only vary in time for situations were the time period is too short for the timescales of, say, cumulus convection (weeks) or for ~ very ~ slow feedbacks like CO2 outgassing.

Figure 1: Schematic diagram of the equilibrium fast - feedback climate sensitivity and Earth system sensitivity that includes surface albedo slow feedbacks.

SO YES slow feedbacks may indeed warm us up some more than just our emissions alone but its a hard one to empirically nail down.

(The models used in the IPCC projections don't generally deal with slow feedbacks from the carbon cycle — they are considered too uncertain to quantify.)

We thus incorporate consideration of slow feedbacks in our analysis and discus - sion, even though precise specification of their magnitude and timescales is not possible.

Some climate scientists, including James E. Hansen, former head of the nasa Goddard Institute for Space Studies, say we must also consider slower feedbacks such as changes in the continental ice sheets.

DO NOT INCLUDE SLOW FEEDBACKS such as reduction of ice sheet size with global warming or release of greenhouse gases from thawing tundra.

Climate model studies and empirical analyses of paleoclimate data can provide estimates of the amplification of climate sensitivity caused by slow feedbacks, excluding the singular mechanisms that caused the hyperthermal events.
