On the other hand, the FAR did not foresee the phase - out of CFCs, missed the importance of biomass - burning aerosols and dust to climate and stated that unequivocal detection of the enhanced greenhouse effect was more than a decade away.

It is important to remember that the enhanced greenhouse effect is not the only factor acting on the climate system.

The possibility that the enhanced greenhouse effect is increasing the severity of Australian droughts, by raising temperatures and hence increasing evaporation, even if the rainfall does not decrease, needs to be considered.»

Patterns of temperature change that are uniquely associated with the enhanced greenhouse effect, and which have been observed in the real world include:

Taking one example of these, while the troposphere has been warming, the stratosphere has been cooling, a feature of warming due to enhanced greenhouse effects, and also due to warming due to reduced reflectance from aerosols.

But, there does seem to me, at least, to be a significant number of folks who are going around downplaying the impact of anything other that SSTs (and enhanced greenhouse effect - raised SSTs, at that).

Though the greenhouse effect itself is completely natural, and very beneficial, global warming scientists believe that anthropogenic (man - made) emissions of carbon dioxide (mostly from burning fossil fuels) have increased CO2 in the atmosphere to a point where we are now experiencing what could be called an «enhanced greenhouse effect».

Simulations of the enhanced greenhouse effect forecast a warming trend of approximately 0.25 to 0.35 º C per decade, or accelerated warming compared to the surface.

How much of the observed rise in Atlantic SST during the past 20 - 30 years is due to enhanced greenhouse conditions is also not agreed upon.

But also see Tol, R.S.J. and A.F. de Vos (1998), «A Bayesian Statistical Analysis of the Enhanced Greenhouse Effect», Climatic Change, 38, 87 - 112 for a rather simlilar study, with rather simpilar conclusions from 12 years ago.

Going back to basics, what is the basis for enhanced greenhouse warming in the arctic?

To quote Karl Braganza from the Bureau as published by that online rag The Conversation, «Patterns of temperature change that are uniquely associated with the enhanced greenhouse effect, and which have been observed in the real world include... Greater warming in winter compared with summer... Greater warming of night time temperatures than daytime temperatures».

This is usually called the Enhanced Greenhouse Effect.

The hazards of excessive investment in the enhanced greenhouse hypothesis, we suppose.

Global warming in the modern era is being driven by increasing concentrations of greenhouse gases in the atmosphere, which leads to an enhanced greenhouse effect.

As the lower atmosphere warms due to an enhanced greenhouse effect, the upper atmosphere is expected to cool as a consequence.

The warming associated with increases in greenhouse gases originating from human activity is called the enhanced greenhouse effect.

That panel's first assessment report in 1990 concluded that «the size of the warming over the last century is... of the same magnitude as natural climate variability» and that «the unequivocal detection of the enhanced greenhouse effect from observations is not likely for a decade or more.»

Such claims of solar variation insufficiency survive because indications of feedback mechanisms were supported only by historical records and statistical associations but were not empirically demonstrated (never mind that situation applies particularly to the enhanced greenhouse hypothesis, the simple fact is that hypothesis is currently politically correct and hence requires no evidentiary support).

Recognizing this limited level of scientific understanding during those years prompted our scientists to work with other leading scientific researchers to investigate the potential enhanced greenhouse effect and its influence on the global climate system.

This is precisely the kind of feedback hypothesized for enhanced greenhouse except this now has a demonstrated physical mechanism and is of such importance we should walk through its function just to be clear.

Firstly, this new work is a severe blow to proponents of the enhanced greenhouse hypothesis and advocates of Anthropogenic Global Warming who have worked so hard to deny solar influence on global climate.

An enhanced greenhouse effect will probably lead to elevated global temperatures (a trend that may have already begun).

The one certainty about climate over the past 31 years is that there has been no enhanced greenhouse effect from GHG emissions as claimed by the IPCC Since 1979 satellite measurements of outgoing longwave radiation have not shown any decreasi in OLR from the increased insulation ascroibed to the enhanced greenhouse effect resulting from the increase in GHG emissions.

A range of GCM and regional modelling studies in recent years have identified a tendency for daily rainfall extremes to increase under enhanced greenhouse conditions in the Australian region (e.g., Hennessy et al., 1997; Whetton et al., 2002; McInnes et al., 2003; Watterson and Dix, 2003; Hennessy et al., 2004b; Suppiah et al., 2004; Kharin and Zwiers, 2005).

4 (c) McGraw Hill Ryerson 2007 The Enhanced Greenhouse Effect: Nitrous Oxide, Ozone and Halocarbons Nitrous oxide, N 2 O, is the third largest contributor to the enhanced greenhouse effect.

Carbon dioxide is not as abundant as water vapour, but in one important way it is a more important greenhouse gas because it is substantially responsible for the enhanced greenhouse effect that causes global warming and climate change.

This enhanced greenhouse effect is not natural.

While known solar variations are less significant than the expected effects of enhanced greenhouse warming, they could either slow, for a time, or accelerate its eventual impact.

But, were the Sun's activity and total radiation to drop in the coming century to levels of the Maunder Minimum, solar effects might reduce the expected surface temperature effects of enhanced greenhouse warming — by at most about 0.5 °C.

When we increase its atmospheric concentration, as we do by burning fossil fuels, it causes an enhanced greenhouse effect, leading to global warming.

And they have been used to make a variety of predictions — including for example that with an enhanced greenhouse effect the upper stratosphere will cool while the troposphere warms, that nights will warm more rapidly than days, and more generally the Hadley Cells and dry subtropics will expand, the continental interiors dry out, storm tracks move northward, the tropopause rise, changes in ocean circulation.

A consequence of increased heating from the human - induced enhanced greenhouse effect is increased evaporation, provided that adequate surface moisture is available (as it always is over the oceans and other wet surfaces).

However, as average global temperatures rise, the atmosphere is able to hold more water vapour, which in turn can add to the enhanced greenhouse effect, raing temperatures further.

Since the skin layer usually needs to tap into solar energy deposited deeper in the ocean to make up its deficit, the skin layer will obviously make use of any extra DLR from an enhanced greenhouse effect.
