The effects of wind changes, which were found to potentially increase temperatures in the Southern Ocean between 660 feet and 2,300 feet below the surface by 2 °C, or nearly 3.6 °F, are over and above the ocean warming that's being caused by the heat - trapping effects of greenhouse gases.

One could assume that there was minimal global mean surface temperature change between 1750 and 1850, as some datasets suggest, and compare the 1850 - 2000 temperature change with the full 1750 - 2000 forcing estimate, as in my paper and Otto et al..

Hence, relatively small exchanges of heat between the atmosphere and ocean can cause significant changes in surface temperature.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

The significant difference between the observed decrease of the CO2 sink estimated by the inversion (0.03 PgC / y per decade) and the expected increase due solely to rising atmospheric CO2 -LRB--0.05 PgC / y per decade) indicates that there has been a relative weakening of the Southern Ocean CO2 sink (0.08 PgC / y per decade) due to changes in other atmospheric forcing (winds, surface air temperature, and water fluxes).

The paper he wrote together with Friis - Christensen in which he found a correlation between solar activity and clouds had a «slight» flaw: it ignored that the period of the study coincided with a big El Nino, and that large scale changes in ocean surface temperature are going to have an effect on cloud formation.

Within the troposphere and between that and the surface, convection (and at the surface, conduction and molecular mass diffusion) are also important — these also respond to changes in temperature so that an imbalance causes a temperature change that causes the imbalance to decay.

Before allowing the temperature to respond, we can consider the forcing at the tropopause (TRPP) and at TOA, both reductions in net upward fluxes (though at TOA, the net upward LW flux is simply the OLR); my point is that even without direct solar heating above the tropopause, the forcing at TOA can be less than the forcing at TRPP (as explained in detail for CO2 in my 348, but in general, it is possible to bring the net upward flux at TRPP toward zero but even with saturation at TOA, the nonzero skin temperature requires some nonzero net upward flux to remain — now it just depends on what the net fluxes were before we made the changes, and whether the proportionality of forcings at TRPP and TOA is similar if the effect has not approached saturation at TRPP); the forcing at TRPP is the forcing on the surface + troposphere, which they must warm up to balance, while the forcing difference between TOA and TRPP is the forcing on the stratosphere; if the forcing at TRPP is larger than at TOA, the stratosphere must cool, reducing outward fluxes from the stratosphere by the same total amount as the difference in forcings between TRPP and TOA.

This is the extremely close correlation between the changes in the mean surface temperature and the small changes in the rotational velocity of the Earth in the past 150 years (see Fig. 2.2 of / / www.fao.org/DOCREP/005/Y2787E/y2787e03.htm), which has been ignored by the mainstream climatologists.

Here we would like to try to distinguish between warming in the nocturnal boundary layer due to a redistribution of heat and warming due to the accumulation of heat... It is likely that the observed warming in minimum temperature, whether caused by additional greenhouse forcing or land use changes or other land surface dynamics, is reflecting a redistribution of heat by turbulence - not an accumulation of heat.

The surface temperature responds to energy transfer between the oceans and atmosphere which varies dynamically as a result of changes in sea surface temperature.

Determining the mechanisms and feedbacks involved in climate change at the end of the last ice age therefore requires an understanding of the relationship between the southern margin ice retreat and connected meltwater events to atmospheric and sea surface temperatures, ice - rafting Heinrich events, sea level rise, and atmospheric greenhouse gas concentrations.

The overall level of consistency between attribution results derived from different models (as shown in Figure 9.9), and the ability of climate models to simulate large - scale temperature changes during the 20th century (Figures 9.5 and 9.6), indicate that such model differences are likely to have a relatively small impact on attribution results of large - scale temperature change at the surface.

By comparing modelled and observed changes in such indices, which include the global mean surface temperature, the land - ocean temperature contrast, the temperature contrast between the NH and SH, the mean magnitude of the annual cycle in temperature over land and the mean meridional temperature gradient in the NH mid-latitudes, Braganza et al. (2004) estimate that anthropogenic forcing accounts for almost all of the warming observed between 1946 and 1995 whereas warming between 1896 and 1945 is explained by a combination of anthropogenic and natural forcing and internal variability.

There is a pretty clear correlation between the ENSO changes and global average surface temperatures in all temperature sets.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

Due to the surface air temperature being tied to the sea surface temperature any change in the resistor efficiency of the air will attempt to prevent that equilibrium between sea and air.

In the opinion of the panel, the disparity between satellite and surface temperature trends during 1979 — 98 in no way invalidates the conclusion of the Intergovernmental Panel on Climate Change report (IPCC, 1996) that global surface temperature has warmed substantially since the beginning of the twentieth centurIn the opinion of the panel, the disparity between satellite and surface temperature trends during 1979 — 98 in no way invalidates the conclusion of the Intergovernmental Panel on Climate Change report (IPCC, 1996) that global surface temperature has warmed substantially since the beginning of the twentieth centurin no way invalidates the conclusion of the Intergovernmental Panel on Climate Change report (IPCC, 1996) that global surface temperature has warmed substantially since the beginning of the twentieth century.

How hurricanes develop also depends on how the local atmosphere responds to changes in local sea surface temperatures, and this atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.18, 25,26,27 So the link between hurricanes and ocean temperatures is complex.

Hence, the panel concludes that at least part of the observed disparity between the 20 - year changes in surface and mid-tropospheric temperature is probably real, but the measurement, modeling, and sampling uncertainties alluded to above make it difficult to precisely attribute the disparity to any particular sources.
