"Any imbalance results in a change in temperature."
For the record, the incorrect/unsourced statement is "Any imbalance results in a change in temperature." Imbalance in systems can result in many other phenomena such as phase change. DTMGO (talk) 00:26, 11 January 2022 (UTC)

Convection permitting models?
I am currently working on effects of climate change on the water cycle and a colleague recommended adding content from this open access paper: "Enhanced future changes in wet and dry extremes over Africa at convection-permitting scale" (link). I'm wondering if information on convection-permitting climate models should also be integrated into this article? This field is outside of my area of expertise so I am unsure.

Do we need the section on box models?
I think the section on box models could probably be deleted. It doesn't seem to say much about actual climate models. For now, I have moved it to the end. EMsmile (talk) 10:16, 1 December 2023 (UTC)

Re-thinking the structure
I would like to use more generic section headings (like "Uses", "Types", "Challenges" and so forth). But I am not deeply enough into this topic to be able to re-arrange things like this. I've reached out the Kevin E. Trenberth and he's sent me some quick inputs as follows:

++++ The section on “box models” should be deleted or changed. Possible structure for model types:

1. zero D energy balance models 2. radiative-convective models. (these are 1D in vertical) 3. atmospheric models (weather prediction). (land, ocean, ice all specified) 4. climate models (modules for atmosphere, ocean, ice, land) not including chemistry: also called GCMs, or AOGCMS 5. climate system models; includes biogeochemistry (atmosphere and ocean), dynamic vegetation on land, aerosols, ozone etc. 6. Earth system models (everything) 7. EMICS 8. MAGICC: Model for the Assessment of Greenhouse Gas-Induced Climate Change. - widely used as a simple box-type model in IPCC; has no water cycle or weather etc. Meinshausen, M., S.C.B.B. Raper, and T.M.L.L. Wigley, 2011a: Emulating coupled atmosphere-ocean and carbon 1 cycle models with a simpler model, MAGICC6 – Part 1: Model description and calibration. Atmospheric 2 Chemistry and Physics, 11(4), 1417–1456, doi:10.5194/acp-11-1417-2011. 9. IAMs. - see box16.2 of my book, deals with all human aspects, economics etc, but simple climate model with no water cycle: "IAMs are mathematical computer models based on explicit assumptions about how the coupled human and natural system behaves. The modules within the IAM are often greatly simplified, but there may be many modules describing the climate, carbon cycle, and various human dimensions including demographics (population), politics, economics, standards of living, and societal behavior. The strength of an IAM is its ability to calculate the consequences of different assumptions and to interrelate many factors simultaneously, but an IAM is constrained by the quality and character of the assumptions and data that underlie the model." You may also like this article from 2020 commentary on models. see esp p 332. then to 335. ++++++ There are lots of books on climate models (see e.g. https://www.cambridge.org/core/books/changing-flow-of-energy-through-the-climate-system/F6DEF9F0033FCD43398BFA9A2BF64FAD). The tough task is how to condense this into a Wikipedia article that laypersons can understand and follow. EMsmile (talk) 11:33, 7 December 2023 (UTC)
