This is an especially important region of the atmosphere because climate models have forecast the deep layer of the lower atmosphere is the area where CO2 - influenced warming should occur first and by the greatest amounts.

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).

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).

This is similar to how the denier claims of no global warming, or of no anthropogenic influence upon warming, or of low climate sensitivity, depend on all observational data being wrong in the same direction.

According to NASA scientists, this was the ninth warmest year in 132 years of recordkeeping, despite the cooling influence of the La Niña atmospheric and oceanic circulation pattern and relatively low solar irradiance.

Paradoxically temperatures in the middle troposphere (400 mb) have been falling, perhaps reflecting a combination of effects, like surface warming, drier middle altitudes, lower solar influence and so on?

While it is «likely» that anthropogenic influences are behind the changes in cold days and warm days, there is only «medium confidence» that they are behind changes in extreme rainfall events, and «low confidence» in attributing any changes in tropical cyclone activity to greenhouse gas emissions or anything else humanity has done.

The salinity levels of the northern ocean region are also influence by the inflow of warm and salty water from lower latitudes in the Atlantic Ocean.

As more optical thickness is added to a «new» band, it will gain greater control over the temperature profile, but eventually, the equilibrium for that band will shift towards a cold enough upper atmosphere and warm enough lower atmosphere and surface, such that farther increases will cool the upper atmosphere or just that portion near TOA while warming the lower atmosphere and surface — until the optical thickness is so large (relative to other bands) that the band loses influence (except at TOA) and has little farther effect (except at TOA).

The influence of aerosols is mostly in the NH, were a significant lower warming (than over the SH) should be visible.

They discuss an even higher solar influence, listing well - known and antiquated sceptic's arguments as the overestimation of 20th century warming due to heat - island effects, or the lower trends in satellite observations.

Tropical Biomes: Areas in the lower latitudes are influenced by warmer temperatures and often abundant precipitation.

• It is very likely that anthropogenic influence, particularly greenhouse gases and stratospheric ozone depletion, has led to a detectable observed pattern of tropospheric warming and a corresponding cooling in the lower stratosphere since 1961.

Certainly, but whether high or low, if the Sun is going to influence global warming then how can a Sun that has constant TSI (averaged over a solar cycle) during 1950 - 2000 play any role in the global warming that was at its strongest over that period?

No doubt you know that low cloud is hypothesised to be the strongest influence on surface warming.

How may low - cloud radiative properties simulated in the current climate influence low - cloud feedbacks under global warming?

The phrasing of the IPCC attribution statement in its fourth assessment report (AR4)-- providing a lower limit for the isolated GHG contribution — may have led to an underestimation of the GHG influence on recent warming.

This means that ENSO had mainly a warming influence and that removing this influence should have led to a much lower warming trend: typically down to +0.06 °C / decade corresponding to the background trend once all (known) natural variability removed (if natural variability can explain a variability of + / - 0.1 °C per decade, it could also explain the background trend of +0.06 °C per decade likely to correspond to a long term cycle — typically 1 millennium long).

Even with the cooling effects of a strong La Niña influence and low solar activity for the past several years, 2011 was one of the 10 warmest years on record.»

92) If one factors in non-greenhouse influences such as El Nino events and large volcanic eruptions, lower atmosphere satellite - based temperature measurements show little, if any, global warming since 1979, a period over which atmospheric CO2 has increased by 55 ppm (17 per cent).

Lawrence Livermore National Laboratory researchers have identified a mechanism that causes low clouds — and their influence on Earth's energy balance — to respond differently to global warming depending on their spatial pattern.

For instance, if you compare neighboring thermometers around the world, and also compare their population densities (as a rough indication of UHI influence), it can be easily demonstrated that substantial average UHI warming occurs even at low population densities, about ~ 1 deg.

Aside of a Low solar influence (top down), in order to weaken / disrupt the PV, warm tropospheric air (bottom up) has to be pumped northward by planetary waves.

Although these hydrological changes could potentially increase soil water availability in previously snow - covered regions during the cool low - ET season (34), this effect would likely be outweighed by the influence of warming temperatures (and decreased runoff) during the warm high - ET season (36, 38), as well as by the increasing occurrence of consecutive years with low precipitation and high temperature (Fig. 4A).

Using seasonal forecast SSTs instead of observations to drive the regional climate model allows scientists to disentangle the influence of low - frequency climate modes like El Nino from human - induced warming.

The fastest warming areas (across Canada and Russia) have a low population density, so maybe that means UHI fails the first test as far as its global influence goes.

Regarding clouds, recent trends suggest a slight decline in total cloud cover over several decades, due to a reduction in low clouds, which exert a net cooling influence, while high cirrus clouds, which are net warmers, have remained relatively constant.

The model underestimates the 1930 - 1940 warming as good for the Arctic as for lower latitudes, and underestimates the lower latitude recent warming, in my opinion as a result of overestimated influences of GHGs and aerosols at one side and underestimated solar influences at the other side.

Further affirmation of the reality of the warming is its spatial distribution, which has largest values at locations remote from any local human influence, with a global pattern consistent with that expected for response to global climate forcings (larger in the Northern Hemisphere than the Southern Hemisphere, larger at high latitudes than low latitudes, larger over land than over ocean).
