I have kept on experimenting with ChatGPT 4o and reached very interesting results. Read this :

Read well : “You’re correct in noting that CO2 itself is not inherently warming. It’s the heat conveyed by hot CO2 emissions that plays a significant role“. It’s exactly my point in my most recent scientific article.
AI also confirms that there is a feedback loop with hot CO2 and volcanic tephras.

ChatGPT says that volcanic tephras can trap and redistribute the heat conveyed by hot CO2 emissions in the lower stratosphere, “potentially warming it for extended periods”.
I then noted that airborne volcanic tephras also make photosynthesis harder. Photosynthesis is endothermic (another of my points) so there is less cooldown happening.


So there are “multiple layers of feedback” in relation with the heat carried by CO2 emissions and volcanic tephra fallout.


Let’s note that “hot emissions (CO2, water vapor or heat from industrial processes) might extend the suspension time of tephras“. That’s a key of the positive feedback loop mentioned above.

So that is why the true greenhouse effect relies on volcanic tephras and human emissions of heat, that can happen as hot CO2 or hot water vapor among other forms of heat emissions. It’s the heat carried that matters, along with the ratio of volcanic eruptions.
Because of the below paragraph on chemical reactions, I enquired on what ChatGPT meant by that.

Here is what I got that’s interesting by asking whether these are exothermic reactions :



So I find all that very interesting and recommend to keep it into consideration when looking at these interactions.
