Sentences with phrase «surface temperature warming thus»

Although the IPCC climate models have performed remarkably well in projecting average global surface temperature warming thus far, Rahmstorf et al. (2012) found that the IPCC underestimated global average sea level rise since 1993 by 60 %.

So this effect could either be the result of natural variability in Earth's climate, or yet another effect of carbon dioxide and other greenhouse gases like water vapor trapping more heat and thus warming sea - surface temperatures.

The surface gets warmer because the thermal lapse rate, a structural element of the atmosphere *, is suspended from a higher altitude and thus intercepts the surface at a higher temperature.

Keeping within a sufficiently small range of wavelengths that the effects discussed in 438 can be set aside, What such band widenning would do, without a surface temperature increase, is simply increase the range of wavelengths at which the same temperature variation accomplishes the same spectral fluxes through the band, thus not changing OLR within the band — the warming that results from such band - widenning should thus tend to increase the OLR within the band.

Actually to reach a new, higher equilibrium temperature, the Earth surface (including oceans) must warm and thus the radiative budget MUST be unbalanced, less radiation must be emitted in space compared to the (unchanged) incoming solar radiation.

The same temperature increase at lower levels and increased OLR outside the band will be accomplished at smaller optical thickness within the band, so the OLR reduction within the band should be smaller and thus there will be a warmer upper atmsopherer near TOA for the same surface temperature.

Starting with zero atmospheric LW absorption, adding any small amount cools the whole atmopshere towards a skin temperature and warms the surface — tending to produce a troposphere (the forcing at any level will be positive, and thus will be positive at the tropopause; it will increase downward toward the surface if the atmosphere were not already as cold as the skin temperature, thus resulting in atmospheric cooling toward the skin temperature; cooling within the troposphere will be balanced by convective heating from the surface at equilibrium, with that surface + troposphere layer responding to tropopause - level forcing.)

Anthropogenic GHG warming is about the Earth's energy balance, and thus, looking at an average global near - surface temperature, or the total ocean heat content can tell us something useful about that energy balance.

Thus the atmosphere would be warmed to a temperature close to the hottest spot on the surface.

Produce evidence of (a) the temperature of the air adjoining the surface being warmer than the surface at night, thus «stopping convection» and (b) any other inversion in calm conditions at night in the troposphere.

The slowed surface warming is due in large part to changes in ocean cycles, particularly in the Pacific Ocean, causing more efficient ocean heat uptake, thus leaving less heat to warm surface temperatures.

The Earth's temperature has warmed in the modern era as a consequence of the strong solar activity during the 20th century (the Modern Maximum) shielding cosmic ray intensification and thus reducing decadal - scale cloud cover, which leads to warming via an increase in absorbed surface solar radiation (as illustrated here by Ogurtsov et al., 2012 and detailed by Avakyan, 2013, McLean, 2014, and others).

He theorizes that the Earth's temperature has warmed in the modern era as a consequence of the strong solar activity during the 20th century (the Modern Maximum) shielding cosmic ray intensification and thus reducing decadal - scale cloud cover, which leads to warming via an increase in absorbed surface solar radiation (as illustrated here by Ogurtsov et al., 2012 and detailed by Avakyan, 2013, McLean, 2014, and others).

By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.

Warming near surface temperatures were thus only one of a whole group of corroborating evidence.

It does magnify the night - time greenhouse effect by warming the clouds or the higher levels of the atmosphere, thus increasing the amount of heat radiated back to the surface; though the overall effect is to reduce net planetary greenhouse warming by limiting the temperature gradient.

Then try 1365/4 for the flux and emissivity of 0.88 (which is closer to that of rock and soil) and you get 287.6 K which is very close to the assumed mean surface temperature and thus obviates any need for that «33 degree of warming» In fact the 0.88 should be even lower and that gives higher temperatures above 290K.

Thus it's not unexpected that surface temperature warming has slowed, and when we account for these factors, we see that the underlying long - term warming trend continues.

In short, global surface temperatures in the 1990s were mostly amplified by El Niños, while those in the 2000s and 2010s thus far have mostly been dampened by La Niñas - a recipe for a temporary surface warming «pause».

During El Niño, the unusually warm surface temperatures in the eastern Pacific lead to changes in atmospheric circulation, causing unusually wetter winters in the southwestern United States and thus wider tree rings (representing more growth of the tree).

Exactly I will add low solar — sunspot numbers less then 40 solar flux sub 90 will cause overall sea surface temperatures to decline, due to less UV light which is the light which penetrates the ocean surfaces to the greatest degree thus warms / cools the oceans depending on it's intensity..

The reason the air and water are warmer than they would be with no greenhouse gases (and thus have increased radiation both directions) is that the lapse rate combined with the high altitude of outgoing radiation to space gives a higher near surface temperature than otherwise.

Because the temperature gradient in a planet's troposphere is the state of thermodynamic equilibrium which the Second Law of Thermodynamics says will evolve, the planet's supported surface temperature is autonomously warmer than its mean radiating temperature, so warm in fact on Earth that we need radiating gases (mostly water vapour) to reduce the gradient and thus cool the surface from a mean of about 300K to about 288K, this being confirmed by empirical evidence (as in the study in my book) which confirms with statistical significance that water vapour cools rather than warms, all these facts thus debunking the greenhouse conjecture.

A percentage change in cloud cover can be used to calculate the additional clear air absorption and water absorption, and thus the W / m2 warming that induced the specific near - surface energy increase and near - surface atmospheric temperature rise.

There is not thus possible a supposed «greenhouse warming amplification» process, it is not evidenced NOW, nor could sufficient energy EVER be so produced to the surface within IrR to induct the Kinetic Energy levels required when measured as Temperature, as they are often within the «greenhouse platform».

Thus in terms of impacts the problem is surface warming — which is described much better by actually measuring surface temperatures rather than total ocean heat content.

Thus, the static stability of the near - surface water increases and the convective mixing of cold surface water with the relatively warm subsurface water is reduced, thereby contributing to the reduction of sea surface temperature in the Circumpolar Ocean.
