«Somewhat counter-intuitively, a land — sea surface warming ratio greater than unity during transient climate change is actually not mainly a result of the differing thermal inertias of land and ocean, but primarily originates in the differing properties of the surface and boundary layer (henceforth BL) over land and ocean (Manabe et al. 1991; Sutton et al. 2007; Joshi et al. 2008 (henceforth JGW08), Dong et al. 2009) as well as differing cloud feedbacks (Fasullo 2010; Andrews et al. 2010).»

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

They also ignored the processes involved, including, but not limited to, the differences in properties of grazed lands compared to woodlands, the effect of the ocean and other sequestration sinks, and the fact the while undergoing deterioration and desertification, poorly managed grasslands are an emission source instead of a sequestration sink due to land use changes.

That's ironic that you mention that particular property of CO2, because there are scientist that theorize that, since CO2 is heavier, the GCM models are not correct — most CO2 produced at Earth's surface NEVER gets well mixed in fact most CO2 gets removed by rainfall, or gets absorbed by plants or the ocean long before it can cause any change in the so - called Greenhouse gas effect (but the GHG theory is not correct anyway) and the fact that they have severly underestimated CO2 upweelinng from the dee

Global ocean changes result from regional changes in these properties, assessed in this section.

There is a risk that small changes in the radiative properties of the atmosphere, in terrestrial hydrology and in ocean chemistry can trigger large responses in the Earth system.

NASA's P - 3 research plane begins flights this month through both clouds and smoke over the South Atlantic Ocean to understand how aerosols change the properties of clouds.

The fact is that temperature effects CO2 by changing the soluability of carbonic acid in the oceans and CO2 effects temperature due to its radiative properties.

The increasing size and changing air - ice - ocean properties of the SIZ are central to recent reductions in Arctic sea ice extent.

NASA's P - 3 research plane begins flights this month through both clouds and smoke over the South Atlantic Ocean to understand how tiny airborne particles called aerosols change the properties of clouds and how they influence the amount of incoming sunlight the clouds reflect or absorb.

Funny, but I haven't noticed any change in the overall heat index, nor is the ocean anywhere near encroaching on my property — and I literally live within 1000 yards (914 meters for the Eurotrash) of the San Francisco Bay.

«Changes in basal melting are helping to change the properties of Antarctic bottom water, which is one component of the ocean's overturning circulation,» said author Stan Jacobs, an oceanographer at Columbia University's Lamont - Doherty Earth Observatory in Palisades, N.Y. «In some areas it also impacts ecosystems by driving coastal upwelling, which brings up micronutrients like iron that fuel persistent plankton blooms in the summer.»

The change in shape of ocean basins causes a change in a property known as resonance.

Here we examine the hypothesis4 that CO2 variations arose from changes in ocean circulation that affected the distribution of chemical properties and thus of P CO 2 in the surface waters of the world ocean.

Although we focus on a hypothesized CR - cloud connection, we note that it is difficult to separate changes in the CR flux from accompanying variations in solar irradiance and the solar wind, for which numerous causal links to climate have also been proposed, including: the influence of UV spectral irradiance on stratospheric heating and dynamic stratosphere - troposphere links (Haigh 1996); UV irradiance and radiative damage to phytoplankton influencing the release of volatile precursor compounds which form sulphate aerosols over ocean environments (Kniveton et al. 2003); an amplification of total solar irradiance (TSI) variations by the addition of energy in cloud - free regions enhancing tropospheric circulation features (Meehl et al. 2008; Roy & Haigh 2010); numerous solar - related influences (including solar wind inputs) to the properties of the global electric circuit (GEC) and associated microphysical cloud changes (Tinsley 2008).

To date, much of the focus of ocean acidification research has been on the response of calcifiers, both algae and invertebrates, to the changing carbonate system, with a particular preoccupation on one property: the hydrogen ion concentration [H +], which is frequently reported as pH owing to the relative ease of its measurement.

Evan, could it be that changes in the ocean modulate the addition of our emissions to the atmosphere, becuase these changes would alter the properties of the ocean as a sink?
