‰ Is right?[edit]

Can somebody check this? 0.04‰ 421 ppm, 421*100/1000000 = 0.0421% not 0.0421‰

you are correct: 421 ppm = 0.421 parts per thousand = 0.0421 percent Plantsurfer 16:31, 29 April 2023 (UTC)[reply]

Some remaining questions in my mind[edit]

I have some remaining questions, after I had done the reworking of the article in December last year (see comments above on this talk page). I had asked them to a content expert who had helped me in the past but no answer yet so I am putting them here in the hope that they can be addressed by someone in future:

My question to you today: could you please take another look at the new article now and tell me what you think? In particular what do you think of the new structure? Note that this article is only one of many climate change articles on Wikipedia, and therefore should not go into too much detail about adjacent topics, like the carbon cycle, photosynthesis, greenhouse gas emissions (in general) or the carbon budget. But it should provide a good overview and point people to the right sub-articles where needed. It should pull everything about CO2 concentrations in the atmosphere together in a concise manner.

Some specific questions:

What do you think of the new (current) structure?
I am actually still wondering how I could introduce the connection to the carbon budget topic better.
I think there might also still be some paragraphs in the article that are outdated or tangential and that could be cut. (e.g. is this section still up to date?: https://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth%27s_atmosphere#Analytical_methods_to_investigate_sources_of_CO2)
Also, have I missed out any key pieces of information from the technical summary of the WG I report?
And have I identified the direct effects correctly by saying: Direct effects of increasing CO2 concentrations in the atmosphere include: increasing temperatures on land and in oceans, ocean acidification and a CO2 fertilization effect on plants and crops.
For the indirect effects, I am pointing people to the article effects of climate change - that should suffice, right? EMsmile (talk) 12:43, 11 May 2023 (UTC)[reply]
