Dr. Johannes Karstensen, co-author of the study, emphasizes: «Only through long - term measurement programmes the connection between the complex oceanic and atmospheric processes can be identified.

A 2008 study led by James Hansen found that climate sensitivity to «fast feedback processes» is 3 °C, but when accounting for longer - term feedbacks (such as ice sheet disintegration, vegetation migration, and greenhouse gas release from soils, tundra or ocean), if atmospheric CO2 remains at the doubled level, the sensitivity increases to 6 °C based on paleoclimatic (historical climate) data.

Introduced in recent years, this term is used to describe the current geological era in which our earth finds itself, defining the human being as the most important factor influencing the planet's biological, geological and atmospheric processes.

Given that the answer to this for atmospheric models is a resounding «NO» (particularly because of sub-grid scale processes which need to be effectively pre-ordained through parameterizations), and given that oceanic circulations have much longer adjustment time scales, yet also have much more intense small scale (gyre) circulations than the atmosphere, my instinct is that we are not even close to being able to trust ocean models without long term validation data.

Climate sensitivity is defined in terms of global averages (there is only one number) but a GCM is fully time - dependent, three - dimensional simulation that typically includes atmospheric and ocean processes.

What I am hearing is a see - saw process of less ice more atmospheric heat, more ice less atmospheric heat in the short term.

It was an appropriate hypothesis that rests in a knowledge gap (freely admitted by climate scientists - again in the IPCC), but Spencer seemed unable to pinpoint how long - term cloud changes can be decoupled from temperature changes (he hypothesised that ocean / atmospheric processes, like ENSO and PDO, can cause long - term changes in cloud dynamics - but didn't show how that happens).

Please realise the difference tween fluctuations in temperature from short term fluctuations within processes of Turbulence (generally «atmospheric») and the release of Kinetic Energy from the slow & longer term reversion of Turbulent Cooling and the attached release of Kinetic Energy from the Masses seen at * (above and principally Oceanic).

15 Key Terms Write down the correct definition Hydro - meteorological Hazard Natural processes or phenomena of atmospheric, hydrological or oceanographic nature, which may cause the loss of life or injury, property damage, social and economic disruption or environmental degradation.

But a big need to find a way to level the playing field between those processes that contribute excessively to ongoing long term atmospheric alteration, and those that don't, so that the latter are on more of an equal playing field, when consumers and businesses both make decisions.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

In an attempt to deal with the problem, the US Atmospheric Science Program (ASP) ``... has as its long - term goal developing comprehensive understanding of the atmospheric processes that control the transport, transformation, and fate of energy related trace chemicals and particulate matter.

-- the atmospheric concentration of CO2 and other GHG's; — the reflective & absorptive characteristics, as a function of wavelength, for the GHG's; — the specific heat and mass of the earth's intermediate - term heat - storage media — the oceans (primarily) and the atmosphere; — the quantity of heat absorbed by phase - changes = ice - melt; and by chemical / biological processes.

This is strong evidence that the long term accumulation in atmospheric carbon dioxide (from both organic and inorganic sources) is a natural process....

In that regard, atmospheric and terrestrial processes and their long - term interactions need to be understood to better support policies on water management.

(2) This means the total NH photosynthesizing biomass has a higher proportion of land plants which interact directly with atmospheric CO2 and hence the bulk C12 - C13 - C14 fractionation process is more characteristic of land plants and more susceptible to both the annual land cycle of air / soil temperatures and short term differences in the input to the atmosphere of C - 13 and C - 14 by anthropogenic sources.

GEM does not adsorb on ice surfaces, as demonstrated by both field and laboratory measurements (34, 35), and we showed that present chemical processes in the shallow firn do not perturb the long - term record of past atmospheric GEM (21).

More recently, attribution of forcings have been made via specific emissions (which may have impacts on multiple atmospheric components) or by processes (such as deforestation) that impact multiple terms at once (e.g., Shindell et al., 2009).
