Nikolov N, Zeller K (2017) New Insights on the Physical Nature of the Atmospheric Greenhouse Effect Deduced from an Empirical Planetary Temperature Model.

Not exact matches

Our evaluation of a fossil fuel emissions limit is not based on climate models but rather on observational evidence of global climate change as a function of global temperature and on the fact that climate stabilization requires long - term planetary energy balance.

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.

You typed: «Planets with a thin atmosphere and insignificant greenhouse effect, on the other hand, have a surface temperature that is close the the estimates from the planetary energy balance model (Figure 3).»

Planets with a thin atmosphere and insignificant greenhouse effect, on the other hand, have a surface temperature that is close the the estimates from the planetary energy balance model (Figure 3).»

Next N&Z because their «miracle» model for planetary temperatures is complete bullshit (and we'll see what they have to say about DALR after Jelbring isn't there any more as a crutch).

And experiments aside, we have scores of empirical observations of rising temperatures, tropospheric lapse rates, energy flux measurements at the top of the atmosphere, modelling experiments, observations of other planetary bodies (Venus is an excellent example of what happens when CO2 concentrations rise well beyond the point of spectral saturation) that all support the greenhouse theory of atmospheres.

Some modelling has shown geoengineering could be effective at reducing the Earth's temperature, but manipulation of sensitive planetary systems in one area of the world could also result in drastic unintended consequences globally, such as radically disrupted rainfall.

The article disputes using blackbody modeling, in total, for calculating planetary surface temperatures.

For instance, given the physics of sulphate aerosols in the stratosphere (short wave reflectors, long wave absorbers), it would be surprising if putting in the aerosols seen during the Pinatubo eruption did not reduce the planetary temperature while warming the stratosphere in the model.

It means that, for every W m $ ^ -LCB--2 -RCB- $ of excess energy we put into our system, our model predicts that the surface temperature must increase by $ -1 / \ lambda = 0.3 $ K in order to re-establish planetary energy balance.
