[Response: Changes in the atmospheric composition are negligible for their effect on the gas law, but not in terms of radiative transfer, so your conclusion is invalid.]

Where you then have a talik, from this combination of geological and radiative forces, and then there is plenty of free gas underneath that can migrate out easily through pathways once there are such tears, and then you add on top of all that that it is a seismically active zone, one can easily see how global warming could greatly amplify the effects of an earthquake at that fault zone.

Halogenated gases currently contribute 12 % to overall radiative forcing.1 While actions under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) are already addressing CFCs and HCFCs, atmospheric concentrations of some HFCs (hydrofluorocarbons) are rising rapidly, by more than 23 % each year.

The second factor is the insulating effect of the atmosphere of which well over 90 % results from atmospheric water in the form of clouds and water vapour with the remaining 10 % due primarily from CO2 and ozone with just a slightly detectable effect from methane and a trivial effect from all the other gases named in tyhe Kyoto Accord that is so small it can't even be detected on measurements of the Earth's radiative spectrum.

The big difference between this scenario is that the radiation from the lamp AND the radiation from the glass originate in materials at significantly higher temperatures than the gases and hence heat IS transferring from HOT to COLD unlike the fanciful «back radiative greenhouse effect» which truly defies the laws of Physics relying instead on pixie dust magic!

The radiative forcing estimates are based on the forcing of greenhouse gases and other forcing agents.5 The four selected RCPs were considered to be representative of the literature, and included one mitigation scenario leading to a very low forcing level (RCP2.6), two medium stabilization scenarios (RCP4.5 / RCP6) and one very high baseline emission scenarios (RCP8.5).

The RCPs should provide information on all components of radiative forcing that are needed as input for climate modeling and atmospheric chemistry modeling (emissions of greenhouse gases, air pollutants and land use).

Thus the 2nd correct answer is «the lower atmosphere is WARMER than A SIMILAR ALTITUDE on a planet without radiative gases.»

If look look back over my comments on this thread, you will note that I repeatedly state that radiative gases can slow the cooling of land surface and by intercepting surface IR they can heat gases in the lower troposphere.

Radiative gases have a critical role in the fluid dynamics of the atmosphere and this has a significant effect on atmospheric temperature.

The flawed AGW calculations that show radiative gases heating the atmosphere are all based on treating the atmosphere as a static body or layer.

My claim is that radiative gases have a very definite effect on atmospheric temperatures.

This reversed in 1976/77 — and the renewed warming sparked renewed interest in the work on radiative properties of gases and the measurements of Charles Keeling.

Land cover and land use change may have an impact on the surface albedo, evapotranspiration, sources and sinks of heat - trapping gases (greenhouse gases), or other properties of the climate system and may thus have a radiative forcing and / or other impacts on climate, locally or globally.

If one inserts a thin and stationary horizontal adiabatic wall (well... ok, «insulated wall») at any height L within a gas column at equilibrium (no net diffusive, radiative or convective heat flows within this column) then the pressure on both sides of the wall integrated over its surface match the weight of the column above.

We can then calculate the radiative forcings for these greenhouse gas concentration changes, based on the formulas from Myhre et al. (1998).

Based on the National Oceanic and Atmospheric Administration's (NOAA) Annual Greenhouse Gas Index (AGGI), the 2016 Global Carbon Project's Methane Budget and the 2017 EPA Greenhouse Gas Inventory, the paper finds that methane emissions from the U.S. natural gas industry account for just 1.2 percent of 2016 global methane emissions and 0.2 percent of total radiative forciGas Index (AGGI), the 2016 Global Carbon Project's Methane Budget and the 2017 EPA Greenhouse Gas Inventory, the paper finds that methane emissions from the U.S. natural gas industry account for just 1.2 percent of 2016 global methane emissions and 0.2 percent of total radiative forciGas Inventory, the paper finds that methane emissions from the U.S. natural gas industry account for just 1.2 percent of 2016 global methane emissions and 0.2 percent of total radiative forcigas industry account for just 1.2 percent of 2016 global methane emissions and 0.2 percent of total radiative forcing.

There have been many «heated» discussions on various blogs as to the hypothetical structure of the atmosphere composed of no greenhouse gases, only non radiative gases.

Unless you see a complex program running such equations iteratively on discrete moving air masses you are not seeing correct modeling of the role of radiative gases in our atmosphere.

Similarly, the climate scenarios were based on 2xCO2 equilibrium GCM projections from three models, where the radiative forcing of climate was interpreted as the combined concentrations of CO2 (555 ppm) and other greenhouse gases (contributing about 15 % of the change in forcing) equivalent to a doubling of CO2, assumed to occur in about 2060.

Moreover, since gas molecules don't absorb IR across the spectrum but only on molecular lines, cutting off the radiative heat flow would not be nearly as effective as simply silvering the walls and pulling a vacuum in the void between the walls.

Even for an increase in CO2 by a factor of 10, the temperature increase does not exceed 2.5 ° K.» Even the IPCC acknowledges radiative gases» inverse logarithmic influence on temperature.

Would it be wrong to think that the radiative mode of heat transfer is also going on within a solid or liquid or gas?

The amount of greenhouse gases in the atmosphere combined with other factors determine the radiative balance, and / or temperature at which relative thermal equilibrium for a planet occurs based on these factors.

Tyndall's main interest was with water vapour and its impact on radiation, but he also dealt with the radiative forcing of other greenhouse gases including carbon dioxide.

Because all 2013 Intergovernmental Panel on Climate Change scenarios — except Representative Concentration Pathway 2.6 (RCP2.6), which leads to the total radiative forcing of greenhouse gases of 2.6 W m − 2 in 2100 — imply that cumulative carbon emission will exceed 1,000 Gt in the twenty - first century, our results suggest that anthropogenic interference will make the initiation of the next ice age impossible over a time period comparable to the duration of previous glacial cycles.»

Ozone has a measurable influence on the Earth's radiative sprectrum centred at around 9.5 microns but it too is not mentioned as a greenhouse gas in the Kyoto Accord (because it would confuse the ozone depletion issue which the environmentalist lobby also promote).

Thus, if a gas has a high (positive) radiative forcing but also a short lifetime, it will have a large GWP on a 20 - year scale but a small one on a 100 - year scale.

Radiative forcing is a way to quantify an energy imbalance imposed on the climate system either externally (e.g., solar energy output or volcanic emissions) or by human activities (e.g., deliberate land modification or emissions of greenhouse gases, aerosols, and their precursors).
