However, radiation changes at the top of the atmosphere from the 1980s to 1990s, possibly related in part to the El Niño - Southern Oscillation (ENSO) phenomenon, appear to be associated with reductions in tropical upper - level cloud cover, and are linked to changes in the energy budget at the surface and changes in observed ocean heat content.

Similarly, many studies that attempt to examine the co-variability between Earth's energy budget and temperature (such as in many of the pieces here at RC concerning the Spencer and Lindzen literature) are only as good as the assumptions made about base state of the atmosphere relative to which changes are measured, the «forcing» that is supposedly driving the changes (which are often just things like ENSO, and are irrelevant to radiative - induced changes that will be important for the future), and are limited by short and discontinuous data records.

This resource is part of the poster, Earth's Energy Budget, which describes the role of incoming solar radiation and the gases in the atmosphere and clouds in maintaining the Earth's temperature.

It cools the atmosphere by absorbing some heat — heat flows from warmer to cooler — and by increased cloud cover that changes the energy budget of the planet.

Terrestrial, solar radiation propagation in the atmosphere; radiative components in energy budgets, weather systems, climate studies; remote sensing

But on larger scales (both in space and time) the earth is a planet of our local star; the sun is our only source of (purely radiative) energy; we have an atmosphere which clearly operates to reduce diurnal variations in temperature (which on black body basis would otherwise be huge, on human scale) and the radiative budget must always be exactly in balance.

«Heat escaping from the ocean through polynyas impacts the large - scale energy budget of the ocean and atmosphere, cloud patterns, and even rainfall...»

The energy budget — the amount of energy that enters and exits the Earth's atmosphere each day — is a clear calculation of our effect on the Earth's climate.

The minus - 18 °C figure quoted by AGWScienceFiction fisics in its fake Greenhouse Effect energy budget, has been stolen from real physics where it refers to the Earth without any atmosphere at all, and that is predominantly nitrogen and oxygen.

For example, Brown and Caldeira (2017) use fluctuations in Earth's top - of - the - atmosphere (TOA) energy budget and their correlation with the response of climate models to increases in GHG concentrations to infer that ECS lies between 3 and 4.2 K with 50 % probability, and most likely is 3.7 K. Assuming t statistics, this roughly corresponds to an ECS range that in IPCC parlance is considered likely (66 % probability) between 2.8 and 4.5 K. By contrast, Cox et al. (2018) use fluctuations of the global - mean temperature and their correlation with the response of climate models to increases in GHG concentrations to infer that ECS likely lies between 2.2 and 3.4 K, and most likely is 2.8 K.

Instead, the authors use the energy budget of the entire atmosphere itself.

If Mr. Rose really wants to improve his reporting and do a general service of advancing a true understanding of the issue of anthropogenic climate change, he needs to do a comprehensive article about Earth's energy budget, and state quite clearly all the different spheres (all layers of the atmosphere, hyrdosphere, crysosphere, and biosphere) in which the signal of anthropogenic warming is both modeled as impacting and then talk about what is data is actually saying in terms of Earth's energy imbalance in all these spheres.
