Among the ice sheet dynamics to fret about I see this change in the temperature of the ice from say -30 C to ice - at - 0C and the subsequent uptake of the heat to go from ice - at - 0C to water - at - 0C as the «dark matter» of the cryosphere.

Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).

The 4 W / m2 TOA forcing is the consequence of an imposed change in CO2 — all changes to LW absorption in the atmosphere as a consequence of that initial change (through water vapour, cloud or temperature profile responses) are feedbacks.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).

First, for changing just CO2 forcing (or CH4, etc, or for a non-GHE forcing, such as a change in incident solar radiation, volcanic aerosols, etc.), there will be other GHE radiative «forcings» (feedbacks, though in the context of measuring their radiative effect, they can be described as having radiative forcings of x W / m2 per change in surface T), such as water vapor feedback, LW cloud feedback, and also, because GHE depends on the vertical temperature distribution, the lapse rate feedback (this generally refers to the tropospheric lapse rate, though changes in the position of the tropopause and changes in the stratospheric temperature could also be considered lapse - rate feedbacks for forcing at TOA; forcing at the tropopause with stratospheric adjustment takes some of that into account; sensitivity to forcing at the tropopause with stratospheric adjustment will generally be different from sensitivity to forcing without stratospheric adjustment and both will generally be different from forcing at TOA before stratospheric adjustment; forcing at TOA after stratospehric adjustment is identical to forcing at the tropopause after stratospheric adjustment).

One driver of temperatures in this region is the abundance and variability of ozone, but water vapor, volcanic aerosols, and dynamical changes such as the Quasi - Biennial Oscillation (QBO) are also significant; anthropogenic increases in other greenhouse gases such as carbon dioxide play a lesser but significant role in the lower stratosphere.

This is done by scaling local to global warming and by «coupled linkages» that show how other climate changes, such as alterations in the water cycle, scale with temperature.»

The Great Lakes, North America's largest freshwater feature, have recently recorded higher water temperatures and less ice cover as a result of changes in regional climate (see also Ch.

For large lake ecosystems, these changes have well - documented effects, such as effects on algal production, stratification (change in water temperature with depth), beach health, and fisheries.

There is concern in the scientific community that the temperature change from now to the end of the century will be roughly the same as the difference between now and the last Ice Age, which occurred 10,000 years ago, resulting in dramatic changes in temperature, weather patterns, water tables, land and biodiversity.

This remains to be seen, of course, but it's important to point out that the trospospheric amplification prediction does not originate in the models but in the basic physics of radiative transfer in combination with the Clausius - Clapeyron relationship describing the change in atmospheric water vapor as a function of temperature.

In turn, temperature change affects atmospheric water vapor as well as the more dynamical components of equator - to - pole insolation and of temperature gradients that vary on timescales of decades to hundreds of years.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditionsas reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditionsAs soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

The upshot is flatlining temperatures observed in the last one or two decades may be caused by a hidden, as yet unidentified homeostatic mechanism mediated by changes in fine details of water vapor distribution (never represented properly in computational models, neither measured ever).

Of course Ferdinand is right not to project catastrophism onto anthropogenic CO2 levels for as you likely know there is a inverse logarithmic relationship between changes in temperature and CO2 levels such that without the assumed positive feedback from water vapour there is no chance of runaway global warming, tipping points or whatever.
