Hammershaft's comment is disturbing to me, as that is how the lines in the graph appear to me as well.
We've already reached and are now starting to exceed:
The global average temperature during the Last Interglacial period, which peaked around 125,000 years ago, was about 0.5–1.5°C warmer than pre-industrial levels.In all seriousness, wish there was more happening to fix this.
A third of the Arctic’s vast carbon sink now a source of emissions, study reveals - https://www.theguardian.com/environment/2025/jan/21/third-of...
Wildfires offset the increasing but spatially heterogeneous Arctic–boreal CO2 uptake - https://www.nature.com/articles/s41558-024-02234-5
It's predicated on thermodynamics, heat equations, and the fact that CO2 is an insulator and that CO2 in the atmosphere has measurably increased as a direct result of fossil fuel extraction.
eg: Manabe, Wetherald 1967.

This directly contradicts another opinion upthread:
> The proxies we have for ancient periods don't allow us to state very much about what rates of warming looked like
although that was from the person that incorrectly, although confidently, claimed:
> the CO2-driving argument is predicated on null-warming in the 1800s
They do seem confused about multiple causes, effects, etc.
The contradiction that you see escapes me. Please explain how the fact that our proxies don't allow us to talk about decade- or century-level temperature movements 50 million years ago contradicts the statement CO2 is a lagging indicator of temperature change through most of the geologic record.
Also, you say I am confused about something. Perhaps. Say in precise language what you think that is, and I will try to clear things up.
