Climate models generally predict that temperatures should increase in the upper air as well as at the surface if increased concentrations of greenhouse gases are causing the warming
It turns out that the upper - air records have not shown the warming that should accompany the reported increases at the surface.
Add in that if it's the sun, the entire atmosphere will warm, since there's just simply more energy put in to the system, whereas if it is CO2 or other blanketing method, there's no extra energy put in, therefore the ground will warm and the upper air cool (since the upper air isn't getting the warming from the lower layers it used to get and the lower layers aren't losing the heat they used to).
The lack of ozone is chilling the middle and upper atmosphere, altering wind patterns in a way that keeps comparatively warm air from reaching the surface.
The radiation to space is made less efficient by the existence of a warm stratosphere above the air, generating IR radiation from above, and limiting the net cooling of the upper troposphere.
The official theory is that photons interacting with CO2 molecules in the upper air give off heat that warms that air, which warms the lower air, which warms the surface.
Just as it is officially predicted that CO2 - driven warming will be greatest in the upper air, which will in turn warm the surface, so it is predicted that the near - surface air will warm the ocean surface, which will warm the deeps.
The 2009 State of the Climate report gives these top indicators: humans emitted 30 billion tons of of CO2 into the atmosphere each year from the burning of fossil fuels (oil, coal, and natural gas), less oxygen in the air from the burning of fossil fuels, rising fossil fuel carbon in corals, nights warming faster than days, satellites show less of the earth's heat escaping into space, cooling of the stratosphere or upper atmosphere, warming of the troposphere or lower atmosphere, etc..
On January 30th, an upper level low - pressure system combined with a warm sub-tropical air mass led to Tucson recording its wettest January day on record at 1.39 in (35 mm).
«Storms like Harvey are helped by one of the consequences of climate change: As the air warms, some of that heat is absorbed by the ocean, which in turn raises the temperature of the sea's upper layers.
So we both agree that upper elevation air must warmed somehow, but he appears to be ignoring the dense Venusian clouds.
Considering the different density of air, would you be so kind an calculate (a rough estimate is ok) how much cooler the upper part would have to be to compensate for say a 1 °C warming of the surface?
Which, in turn, pumps warm lower atmosphere air into the upper atmosphere, where the IR path to space is far shorter.
It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.
* the water vapour content of upper layer of the air (in blue figure 6 - D) will change by about 12 % / K near the tropopause and is reduced by the enhanced cooling of the 250 mbar layer; hence the water vapour radiation will the be from a «lower and warmer» level, with a very significant spectral leverage of a factor of ten (400 cm - 1 for the water vapour w.r.t to 40 cm - 1 for the CO2).
The really cold Arctic air is only in the lowest regions of the atmosphere (below say 5,000 feet), which GISS would fully see, while the satellite also sees air above 5,000 feet and averages that «warmer» upper air with the cold surface air.
Should the vortex be broken up by a gust, the lower half of the vortex would reestablish itself with new warm spinning air from below, and the upper half of the vortex would fill from the bottom with high - level cool air and die off.
When released into the air, they float into the upper atmosphere, where they stay for up to 260 years and rapidly warm the planet.
Craig King - Further to Bob Loblaw's comments; that global surface air temperatures are warming faster than upper ocean temperatures is well - observed and completely uncontroversial.
If a significant portion of heat were being lost from the ocean, then it must warm surface air temperatures, before reaching the upper atmosphere and being radiated out to space.
During hot, humid summer weather, many urban areas experience heat inversions — cold air in the upper atmosphere holds much warmer air close to the ground, sustaining higher - than - average temperatures and trapping smog.
Hurricanes can be thought of, to a first approximation, as a heat engine; obtaining its heat input from the warm, humid air over the tropical ocean, and releasing this heat through the condensation of water vapor into water droplets in deep thunderstorms of the eyewall and rainbands, then giving off a cold exhaust in the upper levels of the troposphere (~ 12 km / 8 mi up).
The second issue is far more complex, namely the inter-relationship with other gases in the atmosphere and what effect it may have on the rate of convection at various altitudes and / or whether convection effectively outstrips any «heat trapping» effect of CO2 carrying the warmer air away and upwards to the upper atmosphere where the «heat» is radiated to space.
