The carbon concentration is at around 430ppm in 2025.
The carbon concentration was at around 415ppm in 2018, when I started climate activism.
The carbon concentration was at around 335ppm in 1976, when I was born.
The historically stable carbon concentration at around 280ppm was still an (incorrect) fact in the textbooks my father was taught at school in the 1960s.

The world is accelerating towards climate breakdown.
