as per usual @jopo the best source of information about CO2's greenhouse effect comes from the world's top scientists rather than through an anonymous poster on an equities blog.
if you actually want to learn about CO2's greenhouse effect could i recommend an internet site science.feedback.org.
Science Feedback says of itself it's a publication verifying the credibility of influential information and media coverage that claims to be scientific in fields that are particularly prone to misunderstandings and misinformation such as climate change and health. It is operated by a not-for-profit organization.
in particular i'd recommend its most recent piece from May 14, 2024, "How CO2 warms Earth through the greenhouse effect and why CO2 is not ‘saturated’ in Earth’s atmosphere."
this article provides deep knowledge of the subject matter. Other articles are also posted at the site.
SCIENCE FEEDBACK:
"Scientists are confident in the finding that increased CO2 concentrations are causing Earth’s temperature to rise.[2]
"As CO2 and other greenhouse gases are emitted into the atmosphere, they trap more of the sun’s energy, leading to warming.
"“It is unequivocal that human influence has warmed the atmosphere, ocean and land,” the IPCC notes in its Sixth Assessment Report.[3]
"While remaining in the atmosphere, CO2 prevents heat from escaping and consequently warms the surface of Earth – a concept that is popularly known as the greenhouse effect."
